Science and Technology for UPSC 2018

These the compiled science and technology notes for UPSC 2018



It is the Indo-Oman Air Exercise.   The fourth edition of BRIDGE is going to be held at Air Force Station at Jamnagar.   The Royal Air Force of Oman (RAFO) is participating with its F-16 Air defence fighters and this is the first time that RAFO F-16s are participating in an air exercise outside the Gulf Countries.


Three years after the national vaccine advisory body recommended the introduction of the measles-rubella vaccine (MR) in the Universal Immunisation Programme (UIP), the vaccine is all set to be introduced from next month in five states and Union territories as a part of the basket of preventive medications that every child born in India is entitled to. The UIP basket already has ten vaccines of which measles is one; once MR is introduced, monovalent measles will be discontinued.

About the disease:

Rubella, or German measles, is a contagious viral infection that causes a distinctive red rash. Though there are no statistics on its prevalence, the health ministry says the disease is endemic in India.

  • It spreads when an infected person coughs or sneezes and can also be passed on from mother to the newborn.
  • Experts say more than two lakh children in India are born deaf, blind, or with heart or brain damage every year due to the congenital rubella syndrome.


The basket of vaccines in India’s Universal ImmunisationProgramme (UIP) was static for many years — until the entry of the Pentavalent vaccine [Diphtheria, Tetanus, Pertussis, Hepatitis B, and Haemophilus B (HIB)], and Japanese Encephalitis vaccines.   There have been regular additions to the basket since. Two new vaccines — Measles- Rubella (MR) and Pneumococcal Conjugate — are lined up for launch in January and February respectively, and a third,Rotavirus Vaccine, will become part of the UIP in 5 states — from February.

What is Pneumococcal Conjugate Vaccine (PCV)?

PCV is a mix of several bacteria of the pneumococci family, which are known to cause pneumonia — hence ‘conjugate’ in the name. Pneumonia caused by the pneumococcus bacteria is supposed to be the most common.   Pneumonia and diarrhoea have long been responsible for the most child deaths in India — approximate estimates say pneumonia is responsible for about 20% of under-5 child mortality in India, of which half are of pneumococcal origin.

What is Rotavirus?

Rotavirus infections are the most common cause of diarrhoea in children. The rotavirus vaccine first became a part of UIP in April 2016.   An estimated 1 lakh children die every year of the disease.   The vaccine is currently being administered

in HP, Haryana, Odisha and AP. From February, it will be a part of UIP also in Assam, Tripura, Rajasthan, Madhya Pradesh and Tamil Nadu.

  • After India, other South East Asian countries opting for fractional doses of IPV: WHO

According to a latest report by WHO, amid a global shortage of injectable inactivated polio vaccine (IPV) polio vaccine, countries in the South East Asian region have now opted for fractional doses of IPV, first adopted by India, to tackle these “challenging conditions”. WHO also observed that by introducing fractional doses of IPV, nations are not only saving vaccine cost but also not compromising on the protection that it provides to the children against polio.


India and the US have signed a Memorandum of Understanding (MoU) for close cooperation and exchange of information pertaining to cyber security. The MoU was signed between Indian Computer Emergency Response Team (CERT-In) and US CERT.

The MoU intends to promote closer co-operation and the exchange of information pertaining to the Cyber Security in accordance with the relevant laws, rules and regulations of each economy and this Memorandum of Understanding (MoU) and on the basis of equality, reciprocity and mutual benefit.


Earlier United States and India signed an MoU in July, 2011 to promote a closer cooperation and timely exchange of information between the organizations of their respective Governments responsible for Cyber Security. Since, 2011 regular interactions between CERT-In and US CERT are taking place to share the information and discuss cyber security related issues. In continuation to the cooperation in cyber security areas both have renewed the MOU.

About CERT-In:

CERT-In (the Indian Computer Emergency Response Team) is a government-mandated information technology (IT) security organization. CERT-In was created by the Indian Department of Information Technology in 2004 and operates under the auspices of that department.

  • The purpose of CERT-In is to respond to computer security incidents, report on vulnerabilities and promote effective IT security practices throughout the country.
  • According to the provisions of the Information Technology Amendment Act 2008, CERT-In is responsible for overseeing administration of the Act.


India has officially become an Associate member of CERN with the Indian government completing its internal approval procedures in respect of the agreement it had signed with CERN on November 21, 2016.

An Agreement was signed in November 2016 to admit India to CERN as an Associate member. But India had to “notify CERN of its final approval for the Agreement to enter into force” and become an Associate member.

Key facts:

As an Associate member India will have full access to all data generated at CERN. As there are many experiments in CERN, there will be plenty of information available.

  • As an Associate member, India can participate in all experiments.
  • Also, whenever any CERN facilities get upgraded and go through maintenance, it will provide opportunities for Indian industries to participate. Indian industry will be entitled to bid for CERN contracts, which will allow it to work in areas of advanced technology.
  • Since Indian scientists will become eligible for staff appointments, it will also enhance the participation of young scientists and engineers in operation and maintenance of various CERN projects.

About CERN:

CERN is the world’s largest nuclear and particle physics laboratory, where scientists and engineers are probing the fundamental structure of the Universe by using the most sophisticated scientific instruments and advanced computing systems.

CERN is based in Geneva on the French-Swiss border. The CERN convention was signed in 1953 by the 12 founding state. India and CERN:

In 1991, India and CERN signed a Cooperation Agreement, setting priorities for scientific and technical cooperation. India and CERN have signed several other protocols since then. But India’s involvement in CERN began in the 1960s with researchers from the Tata Institute of Fundamental Research, Mumbai participating in experiments at CERN. In the 1990s scientists from Raja Ramanna Centre for Advanced Technology, Indore too got involved in CERN experiment. Researchers from TIFR, Raja Ramanna Centre for Advanced Technology and other institutes built components for an accelerator (LEP) and detectors (L3, WA93 and WA89). India was granted Observer status to the CERN Council in 2002.


The Union Cabinet has given its approval to the proposal for India’s taking full membership of the International Vaccine Institute (IVI) Governing Council. The move involves payment of annual contribution of US $ 5,00,000 to the International Vaccine Institute (IVI), Seoul, South Korea.

Background: In the year 2007, with the approval of Cabinet, India joined IVI. India is a long-term collaborator and stake-holder of IVI. In December, 2012 the Board of Trustees (BOT) of IVI approved the formation of its new governance structure. As per the new governance structure of IVI, a member State has to contribute to the IVI by paying a portion of its core budget. Since India is classified in Group-I, it has to pay an annual contribution of US $ 50,000.

About IVI:

International Vaccine Institute (IVI), Seoul, South Korea, established in 1997 on the initiatives of the UNDP, is an international organization devoted to developing and introducing new and improved vaccines to protect the people, especially children, against deadly infectious diseases.

  • Created initially as an initiative of the UN Development Programme (UNDP), IVI began formal operations as an independent international organization in 1997.
  • Currently, IVI has 40 countries and the World Health Organization (WHO) as signatories to its Establishment Agreement.
  • The Institute has a unique mandate to work exclusively on vaccine development and introduction specifically for people in developing countries, with a focus on neglected diseases affecting these regions.


A global coalition to create new vaccines for emerging infectious diseases, designed to help give the world an insurance policy against epidemics was recently launched at the World Economic Forum in Davos, Switzerland. The coalition is named- Coalition for Epidemic Preparedness Innovations.About CEPI:

CEPI, Coalition for Epidemic Preparedness Innovations, is a “public-private coalition that aims to derail epidemics by speeding development of vaccines”.

With an initial investment of US$460m, CEPI – the Coalition for Epidemic Preparedness Innovations will seek to outsmart epidemics by developing safe and effective vaccines against known infectious disease threats that could be deployed rapidly to contain outbreaks, before they become global health emergencies.

CEPI will initially target the MERS-CoV, Lassa and Nipah viruses, which have known potential to cause serious epidemics. It aims to develop two promising vaccine candidates against each of these diseases before any epidemic, so these are available without delay if and when an outbreak begins. CEPI will also scope out potential support for vaccines against multiple strains of the Ebola and Marburg viruses, and Zika.

To achieve all these goals, CEPI will need significant additional investment, and the initial CEPI funders are calling for other governments and philanthropic organisations to join them in helping to protect the world against future epidemics. CEPI is looking to complete its fundraising by the end of 2017.

CEPI also hopes to shorten the time it takes to develop new vaccines to protect against viruses that emerge suddenly as public health threats, as Zika did recently, by capitalising on exciting developments in adaptable vaccine technology and investing in facilities that could respond quickly to previously unknown pathogens.


Researchers have shown that the regulation of G Protein-Coupled Receptors (GPCRs) by new drugs can be simpler than generally thought — it can be mediated by engaging only the end of the receptor, which is called the tail of the receptor.

Significance of these findings: With this, discovering new drugs that bind to G Protein-Coupled Receptors (GPCRs), which are central to almost every physiological process in our body such as vision, taste, immune response and cardiovascular regulation, becomes easier.

Background: Nearly 50% of prescription drugs currently available in the market for the treatment of blood pressure, heart failure, diabetes, obesity, cancer and many other human diseases target GPCR receptors. All these drugs bind to their respective receptors and either activate or stop their signalling.

What is G protein coupled receptor?

G-protein-coupled receptors (GPCRs) are the largest and most diverse group of membrane receptors in eukaryotes. These cell surface receptors act like an inbox for messages in the form of light energy, peptides, lipids, sugars, and proteins.

How GPCRs operate?

Receptors found on the cell surface receive signals and transmit them to inside the cells. A part of the receptor is embedded in the cell membrane and the other part protrudes outside the membrane and inside of the cell.

The part of the receptor that protrudes outside the membrane changes its shape whenever a stimulus in the body binds to it. In response to this change in the outside part of the receptor, a corresponding change happens in the shape of the receptor that is positioned inside the cell.

This change in the shape of the receptor positioned inside the cell allows it bind to other proteins called effectors. These effectors cause specific effects in the cell, referred to as cell signalling, which leads to physiological changes in our body.

About the new method: General understanding is that effector proteins have to simultaneously bind at two sites — the tail of the receptor and the core of the receptor — for the drug to become effective in pulling the receptor inside the cell.

Through specific engineering of the receptor researchers basically disrupted one of the two binding sites, namely the core of receptor. They found that even without the second site, the protein was able to pull the receptor inside the cell by binding just to the tail of the receptor.

There is a key region in the core which the researchers genetically deleted thereby making the core of the receptor ineffective.


Irish scientists have recently identified a new human organ that has existed in the digestive system for hundreds of years.

Key facts:

Named as the mesentery, the organ connects the intestine to the abdomen and had for hundreds of years been considered a fragmented structure made up of multiple separate parts.

Mesentery is a fold of the peritoneum which attaches the stomach, small intestine, pancreas, spleen, and other organs to the posterior wall of the abdomen.

During the initial research, the researchers have found that the mesentery, which connects the gut to the body, was one continuous organ.

Better understanding and further scientific study of the mesentery could lead to less invasive surgeries, fewer complications, faster patient recovery and lower overall costs.


Khanderi, the second Scorpene submarine under Project-75 being built at Mazgaon Docks Limited (MDL) in Mumbai is all set to be launched.

Key facts:

Khanderi is named after the Island fort of Maratha forces, which played a vital role in ensuring their supremacy at sea in the late 17th century.

The state-of-the-art features of this Scorpene class submarine include superior stealth and the ability to launch a crippling attack on the enemy using precision guided weapons. The attack can be launched with torpedoes, as well as tube-launched anti-ship missiles, whilst underwater or on surface. The stealth features will give it an invulnerability, unmatched by many submarines.

The submarine is designed to operate in all theatres, including the tropics. All means and communications are provided to ensure interoperability with other components of a Naval Task Force.


The LIGO India project is likely to be commissioned in 2024. The LIGO India centre, which will study cosmic gravitational waves, will only be the third one in the world. However, this would require Indian universities to churn out young researchers trained in the science, according to the announcement made by LIGO Laboratory.

About LIGO India:

The LIGO (Laser Interferometer Gravitational-wave Observatory) is a massive observatory for detecting cosmic gravitational waves and for carrying out experiments. The objective is to use gravitational-wave observations in astronomical studies.

The project operates three gravitational-wave (GW) detectors. Two are at Hanford in the state of Washington, north-western US, and one is at Livingston in Louisiana, south-eastern US. The proposed LIGO India project aims to move one advanced LIGO detector from Hanford to India.

LIGO research is carried out by the international LIGO Scientific Collaboration (which includes the GEO Collaboration and the Australian Consortium for Interferometric Gravitational Astronomy) and the Virgo Collaboration in Europe.

LIGO India will be set up as a joint scientific collaboration between LIGO laboratories of the California Institute of Technology (Caltech), Massachusetts Institute of Technology (MIT), the US, and three lead Indian institutions, namely, the Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune, Institute for Plasma Research (IPR), Gandhinagar, and Raja Ramanna Centre for Advanced Technology (RRCAT), Indore.

What are Gravitational Waves? Gravitational waves are the ripples in the pond of spacetime. The gravity of large objects warps space and time, or “spacetime” as physicists call it, the way a bowling ball changes the shape of a trampoline as it rolls around on it. Smaller objects will move differently as a result – like marbles spiraling toward a bowling-ball-sized dent in a trampoline instead of sitting on a flat surface.

Why they are useful? These waves will be particularly useful for studying black holes (the existence of which was first implied by Einstein’s theory) and other dark objects, because they’ll give scientists a bright beacon to search for even when objects don’t emit actual light.

With this, mapping the abundance of black holes and frequency of their mergers could get a lot easier.

Since they pass through matter without interacting with it, gravitational waves would come to Earth carrying undistorted information about their origin.

They could also improve methods for estimating the distances to other galaxies.

Why it is difficult to detect these waves?

The reason that gravitational waves have been so difficult to detect is that their effects are tinier than tiny. In fact, the signals they produce are so small that scientists struggle to remove enough background noise to confirm them.


Researchers have made a new ‘alien’ life-form with an expanded genetic code. The modified E.coli bacteria was made by scientists who introduced DNA molecules not found in nature to a common bacterium.

The E. coli bugs are able to grow and reproduce as normal despite containing two extra letters in their genetic code, paving the way for entirely new artificial life forms to be created.

The newly created bacteria now holds on to its human-created X and Y bases while it grows and divides, much like the natural A, C, G and T bases. The key, researchers say, was to tweak existing techniques.


The Indian Space Research Organisation’s Propulsion Research Complex has successfully conducted the stage level test of GSLV MK III’s cryogenic upper stage C-25.

The cryogenic upper stage of the GSLV is the large C-25, the most difficult component of the launch vehicle to be developed. It will be powered by the indigenously developed CE-20 engine.


Aiming to find important clues to the earliest history of the solar system, NASA has announced two missions — one to explore Jupiter’s mysterious Trojan asteroids and the other to study a unique metal asteroid.

The missions, known as Lucy and Psyche, were chosen from five finalists and will proceed to mission formulation, with the goal of launching in 2021 and 2023, respectively.

About mission Lucy:

Lucy will visit a target-rich environment of Jupiter’s mysterious Trojan asteroids. Lucy, a robotic spacecraft, is scheduled for October 2021 launch. It is slated to arrive at its first destination, a main belt asteroid, in 2025. From 2027 to 2033, Lucy will explore six Jupiter Trojan asteroids.

These asteroids are trapped by Jupiter’s gravity in two swarms that share the planet’s orbit, one leading and one trailing Jupiter in its 12-year circuit around the sun.

The Trojans are thought to be relics of a much earlier era in the history of the solar system, and may have formed far beyond Jupiter’s current orbit.

This is a unique opportunity because the Trojans are remnants of the primordial material that formed the outer planets, they hold vital clues to deciphering the history of the solar system. Lucy, like the human fossil for which it is named, will revolutionize the understanding of our origins.

About Psyche mission:

The Psyche mission will explore one of the most intriguing targets in the main asteroid belt – a giant metal asteroid, known as 16 Psyche, about three times farther away from the sun than is the Earth.

This asteroid measures about 130 miles (210 kilometers) in diameter and, unlike most other asteroids that are rocky or icy bodies, is thought to be comprised mostly of metallic iron and nickel, similar to Earth’s core.

The mission will help scientists understand how planets and other bodies separated into their layers – including cores, mantles and crusts – early in their histories.

Psyche, also a robotic mission, is targeted to launch in October of 2023, arriving at the asteroid in 2030, following an Earth gravity assist spacecraft maneuvre in 2024 and a Mars flyby in 2025.


By combining data from several telescopes around the world including India’s Giant Metrewave Radio Telescope (GMRT) in Pune, astronomers have discovered a cosmic double whammy unlike any ever seen before.

Key facts:

By combining data from NASA’s Chandra X-ray Observatory, the Giant Metrewave Radio Telescope (GMRT) in Pune and other telescopes, researchers found what happens when matter ejected by a giant black hole is swept up in the merger of two enormous galaxy clusters.

The two phenomenon have combined to create a stupendous cosmic particle accelerator. This cosmic double whammy is found in a pair of colliding galaxy clusters called Abell 3411 and Abell 3412 located about two billion light years from Earth.

Scientists determined that as the shock waves travel across the cluster for hundreds of millions of years, the doubly accelerated particles produce giant swirls of radio emission.

This discovery solves a long-standing mystery in galaxy cluster research about the origin of beautiful swirls of radio emission stretching for millions of light years, detected in Abell 3411 and Abell 3412 with the GMRT.

This result shows that a remarkable combination of powerful events generate these particle acceleration factories, which are the largest and most powerful in the Universe.

About GMRT:

The Giant Metrewave Radio Telescope (GMRT), located near Pune in India, is an array of thirty fully steerable parabolic radio telescopes of 45 metre diameter, observing at metre wavelengths.

It is operated by the National Centre for Radio Astrophysics, a part of the Tata Institute of Fundamental Research, Mumbai.

At the time it was built, it was the world’s largest interferometric array offering a baseline of up to 25 kilometres (16 mi).

One of the aims for the telescope during its development was to search for the highly redshifted 21-cm line radiation from primordial neutral hydrogen clouds in order to determine the epoch of galaxy formation in the universe.


China is setting up the world’s highest altitude gravitational wave telescopes in a Tibet prefecture close to the Line of Actual Control (LAC) with India, with a budget of $18.8 million.

Key facts:

The telescope aims to detect the faintest of echoes resonating from the universe, which may reveal more about the Big Bang theory.

The telescope, located 5,250 meters above sea level, will detect and gather precise data on primordial gravitational waves in the Northern Hemisphere.

It is expected to be operational by 2021.

The telescope will be located at Ngari. Ngari, with its high altitude, clear sky and minimal human activity is said to be one of the world’s best spots to detect tiny twists in cosmic light.

  • GM mosquito trials to control dengue, chikungunya launched

Outdoor caged trials by Oxitec to demonstrate the efficiency of genetically modified mosquitoes to suppress wild female Aedes aegypti mosquito populations that transmit dengue, chikungunya and Zika were launched on January 23 in Dawalwadi, Badnapur, in Maharashtra’s Jalna district.


Dengue is estimated to infect 5.8 million people in India every year, costing the country over $1B annually. Outbreaks of chikungunya, a viral disease for which no treatment is available, have been increasingly reported in India. Both diseases are transmitted by local populations of Aedes aegypti mosquitoes.


India’s first dedicated space observatory, ASTROSAT, has captured the rare phenomenon of a small six-billion-year-old “vampire” star “preying” on a bigger celestial body. Scientists say the smaller star, also called a “blue straggler,” feeds off its companion star by sucking out its mass and energy, causing its eventual death.

Why is it called a vampire star?

The most popular explanation is that these are binary systems in which the smaller star sucks material out of the bigger companion star to become a blue straggler, and hence is called a vampire star.

The small star becomes bigger, hotter and bluer, which gives it the appearance of being young, while the ageing companion burns out and collapses to a stellar remnant.


ASTROSAT is India’s first dedicated multi wavelength space observatory. This scientific satellite mission endeavours for a more detailed understanding of our universe.

ASTROSAT is designed to observe the universe in the Visible, Ultraviolet, low and high energy X-ray regions of the electromagnetic spectrum simultaneously with the help of its five payloads.

Astrosat aims at understanding the high energy processes in binary star systems containing neutron stars and black holes, to estimate magnetic fields of neutron stars, to study star birth regions and high energy processes in star systems lying beyond the Milky Way galaxy.

This mission has put ISRO in a very exclusive club of nations that have space-based observatories. Only the United States, European Space Agency, Japan and Russia have such observatories in space.


Agni-IV, the Long Range Surface to Surface Ballistic Missile with a range of 4,000 kms was successfully flight tested recently.

The missile is developed by the Defence Research and Development Organisation under the Integrated Guided Missile Development Program.

Agni IV is nuclear capable, with a payload capacity of one tonne of high-explosive warhead.

The sophisticated surface-to-surface missile is equipped with modern and compact avionics to provide high level of reliability.

The most accurate Ring Laser Gyro based Inertial Navigation System (RINS) and supported by highly reliable redundant Micro Navigation System (MINGS), ensures the vehicle reaches the target within two digit accuracy.

The re-entry heat shield can withstand temperatures in the range of 4000 degrees centigrade and makes sure the avionics function normally.

The Agni-IV had undergone one failed and five successful tests over the last five years, with the last one being conducted in November 2015.


The Pinaka Rocket converted to a Guided Pinaka was successfully test-fired from Launch Complex-III, ITR, Chandipur recently.

The Pinaka Rocket Mark-II, which evolved from Pinaka Mark-I is equipped with a navigation, guidance and control kit and has been transformed to a Guided Pinaka. This conversion has considerably enhanced the range and accuracy of Pinaka.

The Guided Pinaka is developed jointly by ARDE Pune, RCI Hyderabad and DRDL Hyderabad. ITR Chandipur provided the range and launch support.


Zero-rating platforms offer free access to a limited number of sites through select telecom providers.

Those who wanted unrestricted access to the entire internet would still have to pay, but the poor would have access to a few useful sites offered by them.   Facebook’s Free Basics is an example.


  • Blazars

NASA’s Fermi Gamma-ray space telescope has identified the farthest gamma-ray blazars, a type of galaxy whose intense emissions are powered by super-sized black holes.These luminous galaxies, known as blazars are the most distant ever detected and are expected to shed light on the cosmic evolution of black holes. Blazars constitute roughly half of the gamma-ray sources detected by Fermi’s Large Area Telescope (LAT).

  • Lagrange Points: Parking Places in Space

– A Lagrange point is a location in space where the combined gravitational forces of two large

bodies, such as Earth and the sun or Earth and the moon, equal the centrifugal force felt

by a much smaller third body.

– The interaction of the forces creates a point of equilibrium where a spacecraft may be

“parked” to make observations.

– There are five Lagrange points around major bodies such as a planet or a star. Three of

them lie along the line connecting the two large bodies.

The first point, L1, lies between Earth and the sun and gets an uninterrupted view of the

sun and free from the occurrence of eclipses.

India’s Aditya Satellite is placed at L1 point.

  • Non-fumigated wheat

– From March 31, 2017, the wheat imports to India must be fumigated with methyl bromide at the port of origin, else, the cargo would be disallowed from entering Indian shores.

What is fumigation?

– Fumigation is a method of pest control that completely fills an area with gaseous pesticides (or fumigants) that suffocates or poisons the pests within.

It is mainly used to control pests in buildings (structural fumigation), soil, grain, and produce.

– It is also used during processing of goods to be imported or exported to prevent transfer of exotic organisms.

Why is India insisting on fumigation?

– It is seen as the most effective way to kill all pests, insects and nematodes.

– Substitution is a costly proposition and a tricky one in colder climates.

– Instead of methyl bromide, aluminium phosphide can be used as a fumigant.

– But what can be done in 16 hours with methyl bromide takes three days with aluminium phosphide and the cost also increases three times.

plant quarantine order

– The Plant Quarantine (Regulation of Import into India) Order, 2003 has a stipulation that all imports of agricultural produce be fumigated with methyl bromide.

  • – However, the developed nations are agitated over this stipulation.

– The reason being Methyl bromide is forbidden in developed nations, and its use was restricted by the Montreal Protocol due to its role in ozone depletion.

– In the past, if fumigation is not done at the port of origin, the consignments can be fumigated at Indian ports on paying a penalty of around of $375 per tonne against the normal fee of $75 per tonne.

– But, from March 31, fumigation will have to be done only at the port of origin.


The main payload was the Cartosat-2D, weighing over half the total weight.

The others were two Indian nanosatellites (INS-1A and INS-1B) and 101 nanosatellites

belonging to research facilities in USA, Kazakhstan, Israel, The Netherlands,

Switzerland, and the UAE.

– Most of the nanosatellites were from a California-based company, which called them “doves”.

– Russia’s Dnepr rocket carried 37 payloads in 2014. Therefore the current mission carried almost 3 times the record number of satellites launched in a single mission.

What is a Cartosat?

– Cartosat-2D is an Earth observation satellite in a sun-synchronous orbit.

– It is the fifth of the Cartosat-2 series of satellites.

– It is used to produce high-resolution images of the Indian landmass for applications like rural and urban management, coastal land use and regulation, monitoring of road networks or water pipelines, and for building various kinds of land information systems.

– A Sun-synchronous orbit is a geocentric orbit that combines altitude and inclination in such a way that the satellite passes over any given point of the planet’s surface at the same local solar time.

  • Ekuverin

– It is the joint military exercise conducted between India and Maldives. Held in  Belagavi, Karnataka.

  • Kamov 226T

– Hindustan Aeronautics Limited and Russian defence firms have finalized the Joint Venture agreement for collaboration in the production of light weight multi-role ‘Kamov 226T’ helicopters in India

– The Kamov 226T is a twin-engine light but multi-role chopper offers services for both military and civilian purposes.

– The helicopters will replace India’s ageing fleet of Cheetah and Chetak

  • ADHD

– Attention deficit hyperactivity disorder (ADHD) is a mental disorder of the neuro developmental type.

– It is characterized by problems paying attention, excessive activity, difficulty controlling behavior which is not appropriate for a person’s age.

– These symptoms begin by age six to twelve, are present for more than six months.

  • Scientists for the first time have successfully implanted world’s smallest pacemaker dubbed as Micra Transcatheter Pacing System (TPS) in a patient in United States.

The pacemaker about size of large vitamin capsule is for patients with bradycardia, a condition characterised by a slow heart rate, usually fewer than 60 beats per minute.

Key Facts

TPS provides the most advanced pacing technology. It was recently approved by the US Food and Drug Administration.It is one-tenth the size of a traditional pacemaker and is the only leadless (wireless) pacemaker approved for use in the US. It can be delivered through a catheter and implanted directly into the heart.Unlike traditional pacemakers, it does not require cardiac wires (leads) or a surgical pocket under the skin to deliver a pacing therapy.


The Food and Agricultural Organization (FAO), a United Nations agricultural agency has called for International collaboration on wheat rust to curb threat to global supplies.

According to studies produced by scientists in collaboration with FAO, wheat in Africa, Asia and Europe is increasingly threatened by fresh groups of wheat rust.

Key Facts

The studies have showed emergence of two new groups or races of both yellow rust and stem rust in various regions of the world.They highlight urgent need for early detection and rapid action to keep the wheat rust under control which spread rapidly over long distances by wind.

What is Wheat Rust?Yellow rust is a fungal disease which turns leaves yellowish and stops the photosynthesis. It is caused by the Magnaporthe oryzae fungus and was discovered in Brazil in 1985. The fungus attacks the leaf of the crop and eats its chlorophyll, thereby affecting the plant’s growth. It can cause up to 20% yield loss. In recent times, due to temperature rise caused by climate change has contributed to the spread of the fungus.

  • Scientists from US and India have found that consumption of litchi fruit on an empty stomach can result in very low blood glucose level and acute encephalopathy leading to seizures and coma, and causes death in Children in many cases. Litchi fruit contains the toxins hypoglycin A and methylenecyclopropyl-glycine (MCPG). Its consumption and skipping evening meals causes very low blood glucose level (less than normal 70 mg/dL) and acute encephalopathy in children.

  • India’s first dedicated space observatory, ASTROSAT has captured the rare phenomenon of a small six-billion-year-old vampire star preying on a bigger celestial body. The vampire star phenomenon is observed when smaller star sucks material (mass and energy) out of the bigger companion star, causing its eventual death. It is also called a blue straggler as small star becomes bigger, hotter and bluer, giving it the appearance of being young, while the ageing companion burns out and collapses to a stellar remnant.


Astrosat is India’s first dedicated multi-wavelength space observatory launched in September 2015. It is one of the major scientific missions of ISRO after the highly acclaimed Chandrayaan-I and Mangalyaan. It is placed at low earth equatorial orbit at altitude of 650 km. It has ability to observe celestial bodies like cosmic X-Ray sources and distant stars in different wavelengths simultaneously.

  • CRISPR/Cas9n : Tuberculosis-Resistant Cows

A team of researchers from China has successfully utilized an innovative form of the genome-editing technique CRISPR to insert a new gene into the cow genome, rendering the animals much more resistant to tuberculosis. Researchers used a novel version of the CRISPR system called CRISPR/Cas9n to successfully insert a tuberculosis resistance gene into the cow genome.

How was this done?

  1. the investigators inserted the NRAMP1 gene into the genome of bovine fetal fibroblasts—cells derived from female dairy cows—using the CRISPR/Cas9n technology.
  2. These cells were then used as donor cells in a process called somatic cell nuclear transfer (therapeutic cloning), where the nucleus of a donor cell carrying the new gene is inserted into an egg cell, known as an ovum, from a female cow.
  3. The ova were nurtured in the lab into embryos before being transferred into mother cows for a normal pregnancy cycle.
  • NASA’s Juno

NASA’s Juno spacecraft recently made its fourth flyby over Jupiter’s mysterious cloud tops. At the time of its closest approach (called perijove), Juno was at about 4,300 km above the planet’s cloud tops. Juno was launched in 2011 on a mission to study Jupiter’s composition and evolution. It’s the first spacecraft to orbit Jupiter since Galileo. Juno spacecraft successfully entered Jupiter’s orbit recently, after a five year journey. At the end of its mission, Juno will dive into Jupiter’s atmosphere and burn up — a “deorbit” maneuver that is necessary to ensure that it does not crash into and contaminate the Jovian moons Europa, Ganymede and Callisto.

The broadcast regulator Trai has recommended introduction of digital terrestrial transmission for broadcast services in a phased manner and complete shut down of analog transmission by end of 2023.There are a number of advantages of digital terrestrial television. The platform  can be adapted to handle new forms of content.Frequency use is much more efficient, allowing for the transmission of 20 to 30 SD channels in the spectrum occupied by a single television channel in an analog signal.DTT offers better quality of images and sound as compared to analog signals.A combination of DTT transmitters at a single location can provide consumers with a range of content options, including radio and video feeds of various qualities.The DTT transmitters have lower power requirements than traditional analog transmitters. The signals can be received easily by moving vehicles and mobile phones.Luxembourg was the first country to shift from analog TV in 2006. Countries in the Americas and Europe followed suite. China is expected to shift by 2018, and Brazil has plans to shut off analog TV towers by 2023.

  • Scientists develop high-quality graphene from soybean

In a breakthrough, scientists have used the humble soybean to make the world’s strongest material graphene commercially more viable.

How was it developed?

Previously, graphene was grown in a highly-controlled environment with explosive compressed gases, requiring long hours of operation at high temperatures and extensive vacuum processing.

Scientists at Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia have developed a novel “GraphAir” technology which eliminates the need for such a highly-controlled environment.The technology grows graphene film in ambient air with a natural precursor, making its production faster and simpler.


Graphene is a carbon material that is one atom thick. Its thin composition and high conductivity means it is used in applications ranging from miniaturised electronics to biomedical devices.

These properties also enable thinner wire connections; providing extensive benefits for computers, solar panels, batteries, sensors and other devices. The potential applications of graphene include water filtration and purification, renewable energy, sensors, personalised healthcare and medicine, to name a few.Graphene has excellent electronic, mechanical, thermal and optical properties as well. Its uses range from improving battery performance in energy devices, to cheaper solar panels.

  • NASA discovers 7 Earth-like planets

US space agency NASA has announced that scientists researching outer space have found the existence of another ‘solar system’ – seven Earth-like planets orbiting a small star in galaxy 40 light years away – opening up the most promising hunting ground so far for life beyond. The Spitzer Space Telescope has found that the planets are as large as Earth and at least three of them are in a “habitable zone”. Almost all of them are rocky and three are likely to have water. Because they are located outside of our solar system, these planets are scientifically known as exoplanets.

Key facts:

This star system is less than 40 light-years from Earth, or 235 trillion miles away, in the constellation Aquarius. At the hub is a small, faint star known as Trappist-1.

  • Rossby waves,

Scientist recently discovered that large scale planetary waves that meander through the atmosphere high above Earth’s surface have been also found to exist on the Sun. From 2011 scientists had the unprecedented opportunity to see the Sun’s entire atmosphere fromNASA’s Solar Dynamics Observatory (SDO), which is placed between the Sun and the Earth.It was supplemented by measurements from NASA’s Solar TErrestrialRElations Observatory (STEREO) mission, which included two spacecraft orbiting the Sun.

  • NASA‘s Jet Propulsion Laboratory (JPL) have successfully located ISRO‘s Chandrayaan-1.

They used ground-based radar technology, i.e., sending microwave beams and listening to echoes, to track the lost device orbiting the moon. Indian Space Research Organisation (ISRO) lost communication with Chandrayaan-1 on August 29, 2009, barely a year after it was launched on October 22, 2008.

  • The NGT has suspended the environmental clearance given to the India-based Neutrino Observatory (INO) which was to come up in the West Bodi Hills in Theni district in Tamil Nadu. To be located 5 km below the Earth surface, this observatory would be used to detect and study neutrinos, one of the fundamental particles of the universe.

The order of the NGT has forced the INO to seek fresh environmental clearance, and approval of the National Board for Wildlife. The latest problem has been triggered by the NGT‘s assessment that the INO site lies at a distance of 4.9 km from a national park in Kerala Idduki district(Mathikettan Shola National Park), at least 100 m inside the 5 km radius beyond which projects do not need National Board for Wildlife approval. Under the guidelines laid down by the Environment Ministry, any project that falls within 5 km from an inter-State boundary or within a notified national park or a sanctuary has to be considered a Category ‘A’ project that involves a number of processes before an EC is granted.

In this case, the MoEF had called it a Category ‘B’ project, for which an Environmental Impact Assessment is not necessary, but the department processed it as an additional measure.

Neutrinos from the sun are falling on us by the trillions every second.

Former President APJ Abdul Kalam said about how neutrinos could be used to recognize the signs of nuclear proliferation from a remote location. He also guessed how neutrinos could help in the search of dark matter and dark energy. 

About neutrino :Detected for the first time in 1959,

They are the second most abundant particles in the world, after photons.

These high-energy particles are produced in natural radioactive decays and all sorts of nuclear reactions happening in nuclear power reactors, particle accelerators or nuclear bombs.

But the most common source of neutrinos are celestial phenomena i.e., the birth and death of stars,

collisions and explosions happening in space.

The core of the Sun is an important source of neutrinos.

They are electrically neutral and almost massless, these neutrinos have an extremely low

tendency to interact with other objects. scientists have to go deep underground to set up special detectors in a bid to catch the faint signals of neutrinos in an environment that is relatively free from ‗noise‘ and disturbance.

  • WHO recently came out with its maiden list of antibiotic-resistant ―priority pathogens. A superbug is a strain of bacteria that has developed extreme AMR(Antimicrobial resistance) i.e become resistant to all available antibiotic drugs.

  • Leptospirosis

It is a zoonotic disease i.e spread from animals to humans, caused by bacteria of the genus Leptospira.

It is commonly known a rat fever and it affects both humans as well as other animals.

The infection is generally transmitted to humans by water that has been contaminated by animal urine

which comes in contact with unhealed breaks in the skin, the eyes, or with the mucous membranes.

. Severe form of leptospirosis is known as Weil’s disease.

  • National Science Day is celebrated all over India with great enthusiasm on 28th of February every year in order to commemorate the invention of the Raman Effect in India by the Indian physicist, Sir ChandrasekharaVenkata Raman on the same day in the year 1928. For his great success in the field of science in India, ChandrasekharaVenkata Raman was awarded and honored with the Nobel Prize in the Physics in the year 1930.

Raman’s experiment:

The violet light of the solar spectrum is isolated with a violet filter and passed through the liquid sample. Most of the light emerging from the liquid sample is the same color as the incident violet beam: the so-called Rayleigh scattered light (the scattering of light by particles in a medium, without change in wavelength. It accounts, for example, for the blue colour of the sky, since blue light is scattered slightly more efficiently than red).

However, Raman, along with K S Krishnan was able to show that some of the scattered light was a different color, which they could isolate by using a green filter placed between the observer and the sample.

  • DRDO recently conducted the successful launch of the interceptor missile Advanced Area Defence (AAD) from Abdul Kalam Island, Odisha.

Key facts:

The AAD is part of the two-layered Ballistic Missile Defence system developed by the DRDO, the research and development wing of the Defence Ministry, with the Hyderabad-based Research Centre Imaarat (RCI). The endo-atmospheric missile is capable of intercepting incoming targets at an altitude of 15 to 25 kms. The BMD consists of two interceptor missiles, the PrithviDefence Vehicle (PDV) for exo-atmospheric ranges and the Advanced Area Defence (AAD) missile for endo-atmosphere or lower altitudes.

  • Defence Metallurgical Research Laboratory (DMRL), Hyderabad, a premier research laboratory of Defence Research and Development Organization (DRDO) and Jindal Stainless (Hisar) Limited (JSHL) have signed the Licensing Agreement for Transfer of Technology of High Nitrogen Steel (HNS) for armour applications.

About High Nitrogen Steel:

High nitrogen steels (HNS) are a new class of high alloy martensitic, austenitic or duplex grades with up to 0.9 mass% of N in solid solution. They are applied e.g. to stainless tools and bearings, in chemical engineering and for high strength non-magnetic components.

HNS is not only tough but also has good strength. In addition to being non magnetic as well as corrosion resistant, the HNS cost is about 40% less compared to Rolled Homogenous Armour Steel (RHA).

  • Defence Research and Development Organisation (DRDO) recently handed over three of its products for induction into the Indian Army.

The products are namely (i) Weapon Locating Radar (WLR), SWATHI, (ii) NBC Recce vehicle and (iii) NBC Drugs.


Weapon Locating Radar (WLR), SWATHI, developed by DRDO’s Electronics & Radar Development Establishment (LRDE), provides fast, automatic and accurate location of all enemy weapons like mortars, shells and rockets firing within in its effective zone of coverage and simultaneously handles multiples projectiles fired from different weapons at different locations.

  • T6P

Using a novel route, an Indian researcher has been able to increase wheat grain yield by 20% and also improve the resilience of wheat to environmental stress such as drought.

How was it done?

By using a precursor that enhances the amount of a key sugar-signalling molecule (trehalose-6-phosphate (T6P)) produced in wheat plant, the researcher has been able to increase the amount of starch produced and, therefore, the yield. The T6P molecule stimulates starch synthesis, which in turn, increases the yield. Since the pathway of T6P molecule is the same in other plants, the yield can potentially be increased by using suitable precursors.

  • Scientists have discovered a chemical in the zebra fish brain that helps reveal how it regrows its retina, a finding that can potentially cure blindness in humans. the levels of GABA (gamma aminobutyric acid), a neurotransmitter, best known for its role of calming nervous activity, drop when the unique self repair process kicks in. Thus, blocking the chemical (GABA) could lead to new treatments for AMD (age-related macular degeneration), the most common cause of blindness and and retinitis pigmentosa.
  • artificial intelligence called “deep neural networks”.

These have been a major part of the game-changing technology behind self-driving cars and Go-playing bots that surpass human performance.  The deep neural network mimics the working of the mammalian visual cortex, known as convolutional neural network (CNN), which breaks the field into overlapping regions. The features found in each region are hierarchically combined by the network to build a composite understanding of the whole picture. Researchers have developed a “deep-learning” algorithm that can read the Indus script from images of artefacts such as a seal or pottery that contain Indus writing.

  • Scientists have found that a special sweet spot in the eye called ‘fovea’ plays a crucial role in humans being able to focus on computer screens and also read, an ability which is unique to Homo sapiens. Located near the optic nerve, the fovea is at its best for fine tasks like reading. Compared to the peripheral retina, however, the fovea is less able to process rapidly changing visual signals.
  • Coal Bed Methane (CBM) is an unconventional form of natural gas found in coal deposits or coal seams. CMB is formed during the process of coalification, the transformation of plant material into coal. It is considered a valuable energy resource with reserves and production having grown nearly every year since 1989. Varied methods of recovery make CBM a stable source of energy.

CBM can be recovered from underground coal before, during, or after mining operations. It can also be extracted from “unminable” coal seams that are relatively deep, thin or of poor or inconsistent quality. Vertical and horizontal wells are used to develop CBM resources. Extraction requires drilling wells into the coal seams and removing water contained in the seam to reduce hydrostatic pressure and release absorbed (and free) gas out of the coal.

India’s CBM potential:  Coalbed Methane (CBM), an unconventional source of natural gas is now considered as an alternative source for augmenting India’s energy resource. India has the fifth largest proven coal reserves in the world and thus holds significant prospects for exploration and exploitation of CBM.

In order to harness CBM potential in the country, the Government of India formulated CBM policy in 1997 . The Cabinet Committee on Economic Affairs has given its approval for marketing and pricing freedom to the Coal Bed Methane (CBM) Contractors to sell the CBM at Arm’s Length Price in the domestic market. According to the policy, while discovering the market price for Arms Length Sales, the Contractor has to ensure a fully transparent and competitive process for sale of CBM with the objective that the best possible price is realized for the gas without any restrictive commercial practices.

  • Li-Fi,

Scientists have developed a new wireless Internet based on infrared rays that is reportedly 100 times faster than existing Wi-Fi networks. A light-based system, also known as ‘Li-Fi,’ could make wireless networks much more secure.Current Wi-Fi uses radio signals with a frequency of 2.5 or five gigahertz. The new system uses infrared light with wavelengths of 1,500 nanometres and higher. The wireless network not only has a huge capacity — more than 40 Gigabits per second (Gbit/s) — but does away with the need to share Wi-Fi as every device gets its own ray of light. The wireless data comes from a few central ‘light antennas’, which can be mounted on the ceiling, that are able to precisely direct the rays of light supplied by an optical fibre. The antennas contain a pair of gratings that radiate light rays of different wavelengths at different angles (‘passive diffraction gratings’). Changing the light wavelengths also changes the direction of the ray of light. A safe infrared wavelength is used that does not reach the retina in the eye. If a user is walking about and a smartphone or tablet moves out of the light antenna’s direction, then another light antenna takes over. The network tracks the precise location of every wireless device using its radio signal transmitted in the return direction. Different devices are assigned different wavelengths by the same light antenna and so do not have to share capacity.

Trade Mark Rules 2017

The Trade Mark Rules, 2017 have been notified by the government. These Rules, which replace the erstwhile Trade Mark Rules 2002, will streamline and simplify the processing of Trade Mark applications.

Some salient features of the revamped Rules are as follows:

Number of Trade Mark (TM) Forms have been reduced from 74 to 8.

To promote e-filing of TM applications, the fee for online filing has been kept at 10% lower than that for physical filing.

Based on stakeholders feedback, the fees for Individuals, Start-ups and Small Enterprises have been reduced from that proposed in the draft Rules – i.e. only Rs 4,500 as against Rs 8,000 for e-filing of TM applications proposed at the draft stage.

Modalities for determination of well-known trademarks have been laid out for the first time.

The provisions relating to expedited processing of an application for registration of a trade mark have been extended right upto registration stage (hitherto, it was only upto examination stage).

Over all fees have been rationalized by reducing the number of entries in Schedule I from 88 to just 23.

Modalities for service of documents from applicants to the Registry and vice-versa through electronic means have been introduced to expedite the process; e-mail has been made an essential part of address for service to be provided by the applicant or any party to the proceedings so that the office communication may be sent through email.

Hearing through video conferencing has been introduced.

The Trade Marks Registry was established in India in 1940 and presently it administers the Trade Marks Act, 1999 and the rules made thereunder. It acts as a resource and information Centre and is a facilitator in matters relating to trademarks in the country.

  • India generates 5 Lakh tonnes of E-waste annually and is the fifth largest producer of e-waste globally. Indian Institute of Science (IISc) researchers have found a novel way to recycle the mounting pile of electronic waste more efficiently and in an environmentally friendly manner.The new approach is based on the idea of crushing e-waste into nanosize particles using a ball mill at very low temperature ranging from -50 to -150 degree C.

 This way of recycling does not require chemicals to separate different metals.

 The crushed material when mixed with water helps to separate different metals by using gravity.

 Unlike the present techniques, it helps to segregate the metals in one phase making the recycling process much simpler.

 Although, it uses high energy, it is scalable and environment friendly.

  • In March 2017, Scientists of Large Hadron Collider accelerator at CERN (European Organisation for Nuclear Research) found five new sub-atomic particles.

 The newly discovered particles are high-energy versions of the omega-c baryon, a particle made up of two strange quarks and one charm quark

 Omega-c-zero is a part of the same family of protons and neutrons, the so-called baryons, because they have three quarks, the fundamental building blocks of matter.

 These particle states are named, according to the standard convention, Omega-c-zero (3000), Omega-c-zero (3050), Omega-c-zero (3066), Omega-c-zero (3090) and Omega-c-zero (3119). The numbers indicate their masses in megaelectronvolts (MeV).

 Characteristic numbers are used to identify the properties of a specific particle and the determination of their theoretical significance.

  • Orchid owners of Himachal Pradesh have, recently, installed the anti-hail storm gun through collective mobilisation of funds.

An anti-hail cannon is a shock wave generator intended to disrupt the formation of hailstones in the atmosphere in the beginning stage.

 An explosive charge of acetylene gas and air is fired in the lower chamber of the machine and the resulting energy passes through the neck and develops a shock wave.

 The shock wave travels at the speed of sound through cloud formations. It splits up the ice bearing layers of the cloud and it is observed that it either comes down as rain or a thin sleet that does not damage the fruit.

  • Cold Atom Laboratory (CAL)

NASA is planning to send an experimental instrument called Cold Atom Laboratory (CAL) on board SpaceX CRS-12 to International space Station to create coldest spot known in the universe.

Aim of the experiment is to study matter at temperatures far below anything found naturally.

About Cold Atom Laboratory (CAL)

This ice chest-sized box has been developed by NASA’s Jet Propulsion Laboratory. The box will have lasers, a vacuum chamber and an electromagnetic “Knife” to cool atoms to 100 Pico Kelvin (one ten-billionth of a degree above absolute zero). At such low temperature all activities of atom theoretically stops.  When atoms are cooled to such low temperatures, they form a distinct form of matter called Bose-Einstein condensate. In such state matter behave less like particles and more like waves. Observing atoms in Bose-Einstein condensate form in earth is extremely difficult because of gravity which continuously pulls the atoms towards the ground. This prevents atoms from holding on to

their wavelike form for longer period to be observed.  However in space ultra-cold atoms can hold on to their wave likeforms longer because of no gravity. Studying these hyper-cold atoms will provide new insights intodark matter and gravity.  Better understanding of superfluids may help in more efficient

transfer of energy.

  • It was revealed that Uber used Greyball, a tool to systematically deceive law enforcement officials in cities where its service violated regulations.

About Greyball

 It is a software tool which Uber designed to help it identify users who violate the terms of service of its app, preventing them from securing rides.

 Uber used this tool to avoid authorities in markets where its service faced resistance by law enforcement or was banned.

 The tool allowed Uber to show images of “ghost” Uber cars on the app or show that no cars were available.

 Greyball used geolocation data, credit card information, social media accounts and other data points to identify individuals they suspected of working for city agencies and blocking their request so that they cannot fine the cab when it reaches to pick them up after booking.

  • The Delhi High court allowed generic drug manufacturers to export patented drugs for the purposes of development, clinical trials and regulatory clearances.


 Bayer had moved the high court to restrain two Indian pharmaceutical companies from exporting generic versions of drugs abroad-

Against Natco Pharma from selling invention Sorafenib, used in treatment of kidney cancer

Against Alembic from selling Rivaroxaban, which is a blood thinner.

 Bayer’s argument was that the compulsory licenses granted for production of these two drugs were for sale within India only and not abroad.


 The court noted that Section 107A of the Patents Act permitted sale of a patented product during the term of the patent but only for the purpose of obtaining regulatory approvals for making and marketing the patented product after the expiry of the patent.

 Section 107A of the Patents Act explains what will not constitute infringement of a patent, and includes selling of a patented invention for the purposes of development.

 The Court also held that absence of law in the destination country to ensure that patented drug is used for the purpose it was originally exported cannot become a ground for barring manufacturing and exporting of a drug.

 The judgement will help Indian drug companies to get regulatory approval before the end of the patent duration.

  • human papillomavirus (HPV) trial in India

A long-drawn legal battle over collusion by the Health Ministry with international NGOs to test experimental drugs onIndians has landed before a Constitution Bench of the Supreme Court.

In 2009, a prominent international NGO had launched a $3.6 million human papillomavirus (HPV) trial in India and tested two vaccines on 16,000 tribal girls in A.P. and Gujarat, apparently without informed consent from the girls‘ parents.

After allegations were made that the girls had suffered adverse effects, the 72nd Parliamentary Standing

Committee Report, implicated the DCGI for licensing the vaccines without adequate research on safety and efficacy; the Health Ministry for not questioning violations in the licensing process; the ICMR for promoting adrug even before it was approved and the NGO for setting up a trial without following basic protocol.

The committee found commercial interests were influencing government policy, and that authoritiesacted as willing facilitators to the foreign institutions.

The committee recommended that henceforth, trials ought to be conducted only in the 330 medical colleges thathave emergency facilities.

It also sought an investigation into the illegal approval of drugs and of doctors who submitted ‗ghost letters‘recommending drugs for approval.

The NGO and the drug companies involved have dismissed the allegations as baseless and oppose the court‘sreliance on the report.

Because of a legal hurdle, the parliamentary report cannot even be looked at by the Supreme Court. Thus, the issue was referred to a Constitution Bench this week.

In 2005, an important change in the Drugs and the Cosmetics Act allowed phase II trials (where the efficacyand safety of an experimental drug is tested) for the first time in India.

It allowed drugs discovered abroad by multinational pharmac companies to be tested on Indians.

But clinical trials in India have been accompanied by large-scale criminality as doctors, officials and pharmacompanies understand well enough that India is a cesspool of corruption where clearances can be had for apittance.

While there have been many cases since, the underbelly of India‘s clinical trial industry came to the spotlight in2005 when 3,300 patients were subjected to 90 clinical trials that followed no protocols at a hospital in MadhyaPradesh.

In American law, such violations automatically attract the criminal charge of battery. In India, the poor don‘tcount at all.

Clinical trials ought to be done under calibrated statutory regimes. But, despite several crimes of enormousproportion where the poor are tested as guinea pigs, nothing has ever been done.

  • Vigyan 2030: Science and Technology as the Pivot for Jobs, Opportunities and National Transformation.

top administrators in Indian science submitted a detailed project report to Prime Minister

Narendra Modi.

The report said: that the stature of Indian science is a shadow of what it used to be because of decades ofmisguided interventions.We have lost self-confidence and ambition and the ability to recognise excellence amongst our own and we oftenchose the mediocre at every level.One of its key recommendations is to have an independent science and technology authority that will have two parallel arms.SPARK (Sustainable Progress through Application of Research and Knowledge), as the body is tentatively named,will be overarching yet have ―light touch governance.

A discovery arm: that can organise the expertise of various organisations across states and regions to solve abasic research problem.

A delivery arm: that will closely work with industry and evolve public private partnerships.

Such an authority will directly report to the Prime Minister.



  • Influenza is an acute viral infection of the respiratory tract which is considered to be one of the lifethreateninginfectious diseases.The virus can be transmitted by direct contact with infected individuals, via contaminated objects. An unexpected emergence of a new and highly virulent influenza virus strains can result in a world-widepandemics with high morbidity and mortality – such as the ―avian flu‖ in 1997 and ―swine flu‖ in 2009.

the types of Influenza?

Influenza is caused by three types of RNA viruses called influenza types A, B and C (considered different genera),which all belong to the family Orthomyxoviridae.

The disease, colloquially called “flu” in humans, is generally caused by the viruses A and B.

Subtypes of influenza A and B viruses can be further characterized into strains. There is a plethora of differentstrains of influenza B viruses and of influenza A subtypes, and new strains of influenza viruses can appear andreplace older strains.

Influenza type A viruses are known to infect people, birds, pigs, horses, whales, seals and other animals, but wildbirds represent the natural hosts for these viruses.

Only a fraction influenza A subtypes (i.e. H1N1, H1N2 and H3N2) are currently in general circulation amongpeople.

Influenza B viruses are responsible the same spectrum of disease as influenza A. And, influenza B viruses donot cause pandemics.

Influenza C viruses are different in comparison to influenza A and B. They cause a mild respiratory illness and arenot thought to cause epidemics.

Why have H1N1 cases shot up?

The spread of influenza virus declines when the temperature shoots up.

But this year, despite the summer temperature crossing 40 degrees Celsius in some parts of the country, the number of H1N1 cases and occasional deaths have not stopped.

According to the WHO, since December 2016, H1N1, H3N2 and Influenza B have been circulating in


During September 2016-February 2017, H3N2 has been predominant in most countries, with only ―low levels ofthe H1N1 viruses circulating in the northern hemisphere, says the WHO.

H1N1 had claimed 160 lives in the country between January 1 and March 26, 2017. The highest number of deaths was reported from Maharashtra.


  • Aspergillus tubingensis is a fungus, which ordinarily lives in the soil. In laboratory trials, the researchers found that it also grows on the surface of plastics. It secretes enzymes onto the surface of the plastic, and these break the chemical bonds between the plastic molecules, or polymers. The fungus was found in Pakistan.


  • scientists have developed ‘grassoline’ — a biofuel derived from grass that could one day power aircraft. Researchers investigated methods that can disintegrate and treat grass until it can be used as a fuel. Due to its vast abundance, grass is the perfect source of energy.


How was it done?

To improve its biodegradability, the grass is pre-treated at first.

Then bacteria are added which convert the sugars in the grass into lactic acid and its derivatives.

This lactic acid can serve as an intermediate chemical to produce other compounds such as biodegradable plastics (PLA) or fuels.

The lactic acid was then converted into caproic acid, which was further converted into decane. Decane can be used in aviation fuel.


  • The High Energy Accelerator Research Organisation (KEK) has completed the much-awaited ‘rolling-in’ of the Belle-II experiment in Tsukuba, Japan.

Belle II is an upgraded detector to allow the experiment to record the enormous numbers of particle processes that are produced by the SuperKEKB accelerator.

This experiment is designed to study violations of the Standard Model and dark matter. The Belle II experiment will accumulate 50 times more data than the previous experiment, Belle, and pursue violations of the symmetry between particles and anti-particles as well as new laws of physics. It is a grand collaboration of 700 scientists from 23 countries. Belle-II has a significant Indian participation both on experimental and theoretical sides.


  • Oxytocin, often referred to as “the love hormone,” is involved in a broader range of social interactions than previously understood.

Key facts:

The new study pinpoints a unique way in which oxytocin alters activity in a part of the brain called the nucleus accumbens, which is crucial to experiencing the pleasant sensation neuroscientists call “reward.”

Oxytocin has also been dubbed the hug hormone, cuddle chemical, moral molecule, and the bliss hormone due to its effects on behavior, including its role in love and in female reproductive biological functions in reproduction.

Oxytocin is a hormone that is made in the brain, in the hypothalamus. It is transported to, and secreted by, the pituitary gland, which is located at the base of the brain. It acts both as a hormone and as a brainneurotransmitter. The release of oxytocin by the pituitary gland acts to regulate two female reproductive functions: Childbirth and Breast-feeding.


  • frog species-Hydrophylax bahuvistara

Researchers have found that skin mucus secreted by a colourful, tennis ball-sized frog species-Hydrophylax bahuvistara, found in Kerala can be used to develop an anti-viral drug that can treat various strains of flu.

Key facts:

The secretion from frog contains peptide, or chain of amino acids. The researchers have named the newly identified peptide “urumin” after the urumi, a sword with a flexible blade that snaps and bends like a whip. Urumin is not toxic to mammals, but “appears to only disrupt the integrity of flu virus”. It seems to work by binding to a protein that is identical across many influenza strains, and in lab experiments, it was able to neutralise dozens of flu strains.


  • Indian Navy recently successfully test fired BrahMos Land Attack Supersonic Cruise Missile from a ship. This variant of Long Range BrahMos Missile was fired from Indian Naval Ship Teg, a Guided Missile Frigate, on a target on land.

Key facts:

BrahMos Missile has been jointly developed by India and Russia, and its Anti Ship variant has already been inducted into Indian Navy.Land Attack variant of BrahMos Missile provides Indian Naval Ships the capability to precisely neutralise selected targets deep inland, far away from coast, from stand-off ranges at sea. The missile has a range of 400km.


  • carbon nanotube (CNT) textiles

Researchers have developed thin carbon nanotube (CNT) textiles that exhibit high electrical conductivity and a level of toughness about 50 times higher than copper films, currently being used in electronics.

How was it prepared?

Tough nano-architectured conductive textile are made by capillary splicing of Carbon nanotubes.

Beginning with catalyst deposited on a silicon oxide substrate, vertically aligned carbon nanotubes were synthesised via chemical vapour deposition in the form of parallel lines of 5 micrometre wide, 10 micrometre in length, and 20-60 micrometre in heights.


  • artificial womb filled with clear liquid

Scientists have successfully tested an artificial womb filled with clear liquid on pre-natal lambs.

A fluid environment is critical for foetal development. The foetus — breathing liquid, as it would in the womb — lies in a clear-plastic sack filled with a synthetic amniotic fluid. It is designed to continue what naturally occurs in the womb. The umbilical cord is attached via tubes to a machine outside the bag, which removes CO2 and adds oxygen to blood passing through it. There are no mechanical pumps — it is the foetus’ heart that keeps things moving. Sheep have long been used in experiments for prenatal treatment, especially because lung development is highly similar.


  • Researchers at the U.S. Naval Research Laboratory (NRL) developed the nickel-zinc (Ni-Zn) batteries in which a three-dimensional Zn “sponge” replaces the powdered zinc anode, or positively charged electrode, traditionally used. Previous zinc-based rechargeable suffer from a major drawback: Repeated cycles of charging and discharging cause zinc atoms to pile up on one of the electrodes. That causes the growth of “dendrites,” tiny zinc spears that can pierce other parts of the battery, causing it to short-circuit and fail.



v  Scientists say they have detected an atmosphere around an Earth-like planet for the first time. Scientists studied a world known as GJ 1132b, which is 4-times the size of our planet and lies 39 light years away.


v  NASA has made the next big announcement about Saturn: The Cassini team found evidence of hydrothermal vents on Enceladus’s ocean floor. Hydrothermal vents are fissures in the rocky core of Enceladus. They release water that has been heated by geothermal activity, and the jets of hot water carry minerals and nutrients that could support life.

v  China’s first cargo spacecraft-Tianzhou-1 cargo resupply spacecraft, docked successfully with the Tiangong-2 space lab recently, marking a major step towards Beijing’s goal of establishing a permanently manned space station by 2022.

About Tiangong-2:

The Tiangong-2 space laboratory, or Heavenly Palace 2, was home to two astronauts for a month last October in China’s longest ever manned space mission.

v  The United States believes the Syrian government employed a sarin-like nerve agent in recent deadly attack in the country’s northwest. Originally conceived as a pesticide, sarin was used by Iraqi dictator Saddam Hussein’s regime to gas thousands of Kurds in the northern town of Halabja in 1988. Inhaled or absorbed through the skin, the gas kills by crippling the respiratory center of the central nervous system and paralysing the muscles around the lungs.

What is Space Debris/Orbital Debris?  Space debris encompasses both natural (meteoroid) and artificial (man-made) particles. Meteoroids are in orbit about the sun, while most artificial debris is in orbit about the Earth. Hence, the latter is more commonly referred to as orbital debris.

Kessler syndrome The term is associated with Space Debris, which used to describe a self-sustaining cascading collision of space debris in LEO (Low Earth Orbit). In April 2017, various space agencies such as NASA, European Space Agency in Washington raised the concern regarding increasing space debris.

Committee on the Peaceful Uses of Outer Space, and Inter-Agency Space Debris Coordination Committee (IADC) advocates Global mitigation measures takes many forms ; including preventing the creation of new debris, designing satellites to withstand impacts by small debris, and improving operational procedures such as using orbital regimes with less debris, and predicting and avoiding collisions.

Committee on the peaceful uses of Outer space  It is an ad-hoc committee under United Nation set up by the General Assembly in 1959 to govern the exploration and use of space for the benefit of all humanity: for peace, security and development.  The committee encouraging space research programmes, and studying legal problems arising from the exploration of outer space

International Space debris Committee It is an international governmental forum for the worldwide coordination of activities related to the issues of man-made and natural debris in space to facilitate opportunities for cooperation in space debris research, to review the progress of ongoing cooperative activities, and to identify debris mitigation options.

NASA has successfully launched its stadium sized super-pressure balloon from Wanaka, New Zealand  This is the third consecutive year when NASA launched the long-duration, heavy-lift super-pressure balloon. About Super Pressure Balloon Technology  The balloon is made from polyethylene film which is stronger and more durable with a potential to float continuously for 100 or more days in the southern hemisphere’s mid-latitude band.  It also carries a payload (cosmic ray fluorescence detector) weighing 2495 kg by International Extreme Universe Space Observatory on a Super Pressure Balloon (EUSO-SPB).  Themain purpose of this mission is to test and validate super pressure balloon technology having long duration flight.  The detector will also help in detecting high energy cosmic rays originating from outside our galaxy system which when interact with nitrogen molecules present in earth’s atmosphere creates a UV Fluorescene lights. This will help in solving the source of these mysterious high energy particles




v  With aim to match the pace of fast changing nature of war, the ministry of defence has released the Joint Doctrine of Armed Forces stressing on the need for synergy amongst the three Services namely Army, IAF and Navy and hone strategy for inter-operability to achieve the political and military objectives in an effective manner.

This doctrine is the second in the series after its first version was released in 2007. It included the lessons learnt over the past ten years and is aligned with the doctrines of individual Services.



The Joint Doctrine will serve as a cornerstone document for application of Military Power in a synergized manner and also establish a broad framework of concepts and principles to understand approach to joint planning and conduct of operations across all the domains of conflict.

Taking the strategic scenario into account, the doctrine said India will have to have deterrent capabilities to protect its interests on the Line of Actual Control (LAC) facing China and Line of Control (LOC) with Pakistan. The document noted that while conflicts the world over for gaining territorial control were diminishing, India, however, has to protect its territory as the LAC and LOC are disputed.

It also mentioned proxy war in Jammu and Kashmir and volatile situation in Af-Pak region is another major challenge for India while describing Radicalisation of youth in some states through social media was another contemporary challenge facing national security, the document said adding management of digital environment is priority area.

The doctrine also talked about the steps initiated for establishment of the “Defence Cyber Agency”, “Defence Space Agency” and “Special Operations Division”.

The doctrine has added surgical strikes, even those across the border, among the nation’s possible responses to terrorist attacks.

The Government has approved Rs. 2,256 crore outlay for Project Saksham to bolster the information technology network for the new GST regime.

Project Saksham is the name given to CBEC’s IT Infrastructure Project. This IT Infrastructure project will enable not just the implementation of Goods and Services tax (GST) but also support all existing services in Customs, Central Excise and Service Tax.

In addition, it will also enable extension of the Indian Customs Single Window Interface for Facilitating Trade (SWIFT) and other taxpayer-friendly initiatives under Digital Indian and Ease of Doing Business of CBEC.

It will enable setting up of an information exchange mechanism with GSTN through the use of pre-agreed Application Programming Interface (API) or other secure methods of message exchange.


  • Internet Service Provider (ISP) ACT Fibernet has announced the launch of 1Gbps (gigabits per second) wired broadband internet services in Hyderabad, making the `City of Pearls’ India’s first `Giga City’.


  • The Union Cabinet has given its approval for setting up of Indian Institute of Petroleum and Energy (IIPE) at Visakhapatnam in Andhra Pradesh as “an Institute of National Importance” through an Act of Parliament.

The Institute will have the governance structure as well as legal mandate to grant degrees in a manner similar to that enjoyed by IITs. A separate Act will also impart the required status to the Institute to become a “Centre of Excellence” in petroleum and energy studies.


  • The second spell of Hindu new year and harvest festivals falls are being celebrated across the country:

Bengalis celebrate Poila Boishakh.

Malayalis celebrate Vishu.

Tamilians celebrate Puthandu.

Assamese celebrate Rongali Bihu.

Punjabis celebrate Baisakhi.

Odia celebrates Maha Vishuba Sankranti.



  • The GBU-43/B – dubbed the ‘Mother of all bombs’ – has been dropped on an Islamic State complex in Afghanistan by the US forces.

The Moab or GBU-43/B is the world’s largest non-nuclear weapon.



  • Nepal and China are planning to hold the first-ever joint military exercise- Sagarmatha Friendship-2017, with a special focus on combating terror and disaster management.



  • Scientists have developed a novel way to 3D-print objects using glass, an advance that could be used to make very small optical components for complex computers.

The process is known as Stereolithography. Stereolithography is a form of 3D-printing technology used for creating models, prototypes, patterns and production parts in a layer by layer fashion using photopolymerisation, a process by which light causes chains of molecules to link, forming polymers.

The material, which remains a liquid, is washed out in a solvent bath, leaving only the desired cured structure. The polymer still mixed in this glass structure is subsequently removed by heating.


  • Survey of India launched a new web portal called ‘Nakshe’ on its 250th anniversary recently. The New Policy envisages two series of maps- the Defence Series Maps (DSMs) and the Open Series Maps (OSMs).  The DSMs will be for exclusive use for defence forces and authorized Government Departments. Their policy would be determined by the Ministry of Defence.  Policy on OSMs will be the responsibility of Survey of India/Department of Science and Technology.

Topographic maps or Open Series Maps (OSM) would be available for free download on the ‘Nakshe’ portal. Maps would be available in pdf format on 1:50000 scale through Aadhar enabled user authentication process. Aadhar is there to make sure that only Indians are able to access them.

Survey of India : It is the principal mapping agency of India formed in 1767 headquartered in Dehradun.  It prepares map for both civilian and military purposes.  It is headed by Surveyor General of India.  It is the oldest scientific department in India functioning under the Department of Science and Technology.

  • DATA EXCLUSIVITY This refers to exclusive rights, granted over the pharmaceutical test data submitted by companies to drug regulatory authorities for obtain market authorisation. It means that information concerning a drug’s safety and efficacy is kept confidential for a period of, say, five or ten years.  It is a form of legal monopoly protection for a drug, over and above the patent protections. This is given expressly to compensate for the investment made during clinical trials. It implied that regulators cannot approve a similar drug with similar data for the next five years.

TRIPS plus measures It means going beyond the TRIPS provisions. TRIPS plus provisions are frequently pushed as a part of free trade agreements between developed and developing countries. Some such provisions are:

  1. Data exclusivity – one of the most worrying demands in RCEP negotiations.
  2. Patent term extensions are given to compensate the company for delays in processing patent applications. A patent term extension will give another five-year monopoly to the innovator company.

Many developed countries have even signed Anti-Counterfeiting Trade Agreement (ACTA) which establishes international standards for IPR enforcement outside WTO and WIPO. It is beyond the mandate of TRIPS agreement and would prevent drug regulators to use the data, submitted by Originator Company, for approving bioequivalent versions of the same drug, which would prevent generics from entering into market. It would prolong monopoly even after expiry of 20-year period and will lead to evergreening of patents negating the impact of Section 3(d) of patent act and blocking of compulsory licensing.  Even for establishing bioequivalence, clinical trials would be repeated on human subjects which is immoral and unethical.  Giving exclusivity just on the basis of money spent would set bad precedent for other industries which may now claim IP-like rights.


  • Scientists have developed a light-weight, paper-based device that can harvest energy from body movements to power sensors and watches.  The finding is based on triboelectricnanogenerators (TENGs) system which makes the energy through Triboelectrification. Triboelectricnanogenerator (TENG) is based on organic material to convert mechanical energy into electricity. It is a sensor that directly converts a mechanical triggering into a self-generated electric signal for detection of motion, vibration, mechanical stimuli, physical touching, and biological movement.  It can be applied to harvest all kinds of mechanical energy available in our daily life, like motion, walking, rotation, wind, automobile, flowing water, etc.
  • National Council of Science Museums (NCSM) under Ministry of Culture has set up a Science City at Kolkata and Regional Science City at Pushpa Gujral Science City at Kapurtala, Punjab andGujarat Science City at Ahmadabad, Gujarat have also been set up.

About Science Cities Scheme

It provides for setting up of Science Cities in all the states of the country. States desirous of setting up a Science City under this Scheme have to provide land, share the cost of setting up of

facilities and maintain a corpus for its upkeep and maintenance.

GSAT – 9

South Asia Satellite GSAT-9 was launched by GSLV-F09 on Friday, May 05, 2017 from Sriharikota. GSAT-9 is a Geostationary Communication satellite realised by India. The primary objective of GSAT-9 is to provide various communication applications in Ku-band with coverage over South Asian countries.


NASA has released a new movie sequence showing a close view of Saturn‘s atmosphere as the Cassini spacecraft swooped over the ringed planet during the first of its Grand Finale‘ dives. Cassini-Huygens was a joint project between NASA, the European Space Agency and the Italian Space Agency.

Lunar Palace

 Chinese students will live in a laboratory simulating a lunar-like environment for up to 200 days as Beijing prepares for its long-term goal of putting humans on the moon.  The volunteers will live in the sealed lab (dubbed the “Yuegong-1”, or “Lunar Palace”) to simulate a long-term, self-contained space mission with no input from the outside world.  Human waste will be treated with a bio-fermentation process, and experimental crops and vegetables grown with the help of food and waste by products.

NASA’s  “bioregenerative life support system”

NASA scientists are developing an inflatable cylindrical greenhouse for outer space. The Prototype Lunar/Mars Greenhouse project uses what’s called “bioregenerative life support system” that mimics Earth’s environment to be able to grow plants outside our planet. The prototype involves an inflatable, deployable greenhouse to support plant and crop production for nutrition, air revitalisation, water recycling and waste recycling.


Kodaikanal Solar Observatory

 Every day, since 1904, staff at the Kodaikanal Solar Observatory in Tamil Nadu have aimed their telescope at the sun, freezing the images of its disc. While spectroheliograms‘ were taken at the Kodai observatory since 1902, it was in 1909 that the data was used to discover the Evershed effect – that gases in sunspots flowed radially outwards.


Solibacillus kalamii

 Jet Propulsion Laboratory  of NASA for work on interplanetary travel, discovered the new bacteria on the filters of the International Space Station (ISS) and named it Solibacillus kalamii to honour the late President. Even as it orbits the earth some 400 kilometres above, the ISS is home to many types of bacteria and fungi.  These spore formers tend to withstand high radiation and also produce some useful compounds protein-wise which will be helpful for biotechnology applications.







The Army carried out a successful test of the advanced BrahMos Block III Land Attack Cruise Missile (LACM) in the Andaman and Nicobar Islands on May 3, 2017.

  • 3D Bio-Printer

Researchers have successfully generated cartilage tissue using a 3D bioprinter, an advance that could lead to new treatments for osteoarthritis.  Previously, Scientists have found a new bio-ink for 3D printing with stem cells that allows printing of living tissue known as bio-printing.  The new bio-ink contains two different polymer components: a natural polymer extracted from seaweed and a sacrificial synthetic polymer used in the medical industry.


  • Methane into Methanol

Researchers have developed a one-step process that uses water to convert methane to methanol.  Methane has been identified as a greenhouse gas. Whereas, Methanol, on the other hand, has been considered a good alternative to gasoline for use in automobile engines.

 It is currently made using a variety of techniques and basic materials including coal, natural gas and even municipal waste.  In this new effort, water is used to oxidize methane over a bed of copper containing zeolite — the unique structure of the mineral lets the water behave as an oxidant. The team claims the process is 97% efficient, emitting only methanol and hydrogen.


  • Immunotherapy

 Scientists have discovered a simple and practical way to kill cancer cells by using light to steer immune cells to attack the tumours. Immunotherapy is different from radiation or chemotherapy. Instead of directly killing cancer cells, immunotherapy tells the immune system to act in certain ways by stimulating T cells to attack the disease. But the problem is that immunotherapy can cause the immune system to overreact or under-react.  Recently, scientists have conducted a study to understand and develop light-sensitive molecules (channelrhodopsin) that could efficiently guide T cells towards tumours.


  • Combustible Ice

Combustible ice is a frozen mixture of water and concentrated natural gas. Technically known as methane hydrate, it can be lit on fire in its frozen state and is believed to comprise one of the world‘s most abundant fossil fuels.  Commercial development of thisfrozen fossil fuel has now moved closer to reality after Japan and China successfully extracted the material from the sea floor off their coastlines.  Large-scale production, if not done properly, could flood the atmosphere with climate-changing greenhouse gases.  Methane hydrate has been found beneath seafloors and buried inside Arctic permafrost and beneath Antarctic ice.


  • Zika virus in Gujarat

 WHO has reported the first three ―laboratory-confirmed cases of Zika virus disease in India — all from Bapunagar area of Ahmedabad. Zika virus is a member of the virus family Flaviviridae.It is spread mostly by the bite of an infected Aedes species mosquito (Ae. aegypti and Ae. albopictus).

 Its name comes from the Zika Forest of Uganda, where the virus was first isolated in 1947.

 It can be passed from a pregnant woman to her fetus. Infection during pregnancy can cause certain birth defects. There is no vaccine or medicine for Zika.  Zika infection during pregnancy can cause a birth defect of the brain called microcephaly and other severe brain defects. It is also linked to other problems, such as miscarriage, stillbirth, and other birth defects. There have also been increased reports of Guillain-Barré syndrome, an uncommon sickness of the nervous system, in areas affected by Zika.


  • Ransomware

 It is malware that encrypts the files on an infected system and then demands a ransom to decrypt them, with escalation in the demand over time. The ransom demand is in Bitcoins, the cyber cryptocurrency that is hard to trace. The Wanna Cryptor 2.0 ‗ransomware‘, aka WannaCry, spreads using a flaw in older Microsoft Windows systems.




CLUSTERED REGULARLY INTERSPACED SHORT PALINDROMIC REPEATS (Crispr) and its associated protein (Cas9) have been resulted in speculation about a new technology race between the US and China. Scientists all over the world are now able to carry out gene editing at costs much lower than ever before, and much more accurately.

 The enhanced tinkering with DNA can be used to achieve end goals as diverse as enhancing crop quality and disease resistance, treating genetic diseases, and even addressing the associated risk of antibiotic resistance through a Crispr pill that substitutes antibiotics.

India can be an attractive destination for a number of multinational pharma companies because of the advances in nanotechnology and bioinformatics in place. They can either outsource some part of their research or buy the siRNA products or nano-carriers for RNA delivery from India.

 This polymeric molecule—essential for regulation and expression of genes—has already been the subject of research, in areas such as RNA interference (RNAi) and antisense technology.


What are RNAi& antisense technology?

RNAi: It is a gene silencing technology that inhibits protein synthesis in target cells using double-stranded RNA. RNAi has huge significance within the Indian context, considering the deep-seated resistance over the years to Bt cotton and other GM seeds.  Recently, GM mustard received regulatory approval from the genetic engineering appraisal committee, only to get stalled later on account of a petition filed before the Supreme Court.

 So,RNA-reliant solutions could be a viable alternative.

 Also, RNAi technologies are now known to formulate drugs capable of reducing cholesterol levels by half.  This technology also finds immense importance in treating acute viral infections like AIDS.


Antisense Technology: It achieves the same result as RNAi, but only through single-stranded RNA.

 Antisense technology has shown promising results in producing a variety of tomato with increased shelf-life commonly known as FlavrSavr.


The future could potentially be witness to the use of antisense technology to target cancer.


 India faces two major challenges hindering progress in RNAi and antisense technologies.

1.Lack of efficient and targeted delivery vehicles: While some Indian institutes have developed drug delivery vehicles capable of delivering proteins, much less has been done to develop vehicles capable of carrying silencing reagents such as small interfering RNA (siRNA).

(India has a programme: programme on nano-biotechnology)

2.Minimal development of silencing reagents: They ensure significant, specific, consistent and lasting knockdown of the target gene.  The drug controller general of India (DCGI) has granted its nod to the first-ever clinical trial of siRNA therapy in India, in 2016.  The number of such trials is negligible when compared to the total number of clinical trials in our country.


JUNE 2017





• GSLV Mk III is a three-stage heavy lift launch vehicle developed by ISRO. The vehicle has two solid strap-ons, a core liquid booster and a cryogenic upper stage. GSLV Mk III is designed to carry 4 ton class of satellites into Geosynchronous Transfer Orbit (GTO) of 36,000 km; or about 10 tons to Low Earth Orbit (LEO) of up to 800 km., which is about twice the capability of GSLV Mk II.• The indigenous GSLV-Mark III will make a bid to breach a heavy-lift rocket club. The U.S., Russia, Europe, China and Japan are already there.  The success of the first full flight of Mk III will mean that soon, Indian communication satellites can be lofted into space from within the country. First developmental flight of GSLV MK III D1 successfully placed GSAT -19 in Geosynchronous Transfer Orbit on June 05 2017. Launch of GSAT-19, is perhaps ISRO’s most important mission in the last three decades. This is bigger in technological significance than even the hugely popular Chandrayaan or Mangalyaan space missions. But ever since the cancellation of the original Russian deal of cryogenic engine ( with ToT), ISRO got down to develop the cryogenic technology on its own at the Liquid Propulsion Systems Centre at Thiruvananthapuram. What is a Cryogenic engine?

Cryogenics is the science that addresses the production and effects of very low temperatures.  A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel or oxidizer. That is, its fuel or oxidizer (or both) are gases liquefied and stored at very low temperatures. Amongst all rocket fuels, hydrogen is known to provide the maximum thrust. But hydrogen, in its natural gaseous form, is difficult to handle, and, therefore, not used in normal engines in rockets like PSLV. However, hydrogen can be used in liquid form. The problem is hydrogen liquefies at very low temperature, nearly 250 degrees Celsius below zero. To burn this fuel, oxygen also needs to be in liquid form, and that happens at about 90 degrees Celsius below zero. Creating such a low-temperature atmosphere in the rocket is a difficult proposition, because it creates problems for other material used in the rocket.




Cartosat-2E launched on 23 June.

ISRO is set to launch Cartosat – 2E along with 30 other satellites in PSLV C-38. It is  Indian remote sensing (IRS) satellite that can send pictures from an orbit 505 km above the earth.  Cartosat is a series of earth observation satellites placed in Polar Sun Synchronous Orbit (PSSO). The imageries from Cartosat-2 series satellite will useful for cartographic applications, urban and rural applications, coastal land use and regulation, utility management like road network monitoring, water distribution, creation of land use maps, change detection to bring out geographical and manmade features and various other Land Information System (LIS) and Geographical Information System (GIS) applications. It will provide useful space-based data for decision makers in Smart City and AMRUTH projects. It has a resolution of 0.6 metres, which means it can spot even smaller objects within a square of 0.6 m by 0.6 m.

Once this satellite becomes operational, it would be handed over to the defence forces, which have their own infrastructure, which includes ground stations, and trained manpower to access data. The co-passenger satellites include 29 Nano satellites from 14 countries—Austria, Belgium, Chile, Czech Republic, Finland, France, Germany, Italy, Japan, Latvia, Lithuania, Slovakia, the United Kingdom and the United States of America—besides a nano satellite from India.




It is one of the nano-satellites from India sharing space in PSLV C-38 mission which carries CARTOSAT and 29 other nano-satellites from 14 countries. NIUSAT was designed and developed by the Noorul Islam University in Tamil Nadu. This nano-satellite is built for disaster management and crop monitoring,



KalamSat, named after former president of India APJ Abdul Kalam, is the world’s smallest and lightest satellite built by students from Tamil Nadu.  This is the first time that an Indian student’s experiment has been carried out by NASA.  It weighs about 64 grams which is lighter than a smart phone and made of reinforced carbon fibre polymer.  It is 3D printed satellite and it is for the first time that 3-D printing technology is being used in space. The main role of the satellite will be to demonstrate the performance of 3D-printed carbon fibre.




NASA-ISRO Synthetic Aperture Radar satellite (NISAR) is the world’s most expensive earth imaging satellite.  NISAR is dual frequency RADAR, it is an L-band and S-band RADAR. It is the first such satellite using dual frequency RADAR.  The S-band is being built by ISRO and L-band by NASA. It is expected that the NISAR satellite will be launched in 2021 from India using the Geo-synchronous Satellite Launch Vehicle (GSLV).  One of the main purposes of the mission is to observe Earth and establish a general pathway for future joint missions for Mars exploration.  It will take weekly snapshots of earth that will provide time lapse images of the motion of tectonic plates, ice sheets and changes in vegetation over land in agriculture and forests.  NISAR will provide a means of resolving highly spatial and temporally complex processes ranging from ecosystem disturbances, to ice sheet collapse and natural hazards including earthquakes, tsunamis, volcanoes, and landslides.


Hottest planet in the Universe

Scientists have discovered the hottest known planet “KELT-9b” located 650 light years from Earth.

• The Jupiter-like planet orbits a massive star KELT-9 and is warmer than most stars in the universe.

• The ultraviolet radiation from the star it orbits is so brutal that the planet may be evaporating away under the intense glare, producing a glowing gas tail.  It is tidally locked to its star as the moon is to Earth. The day side of the planet is perpetually bombarded by stellar radiation, and, as a result, the planet is so hot that molecules such as water, carbon dioxide and methane cannot form there.


Third gravitational wave detection

• The LIGO detectors in the U.S. have detected yet another merger of two black holes.  Named GW170104, this signal marks the third confirmed detection of gravitational waves coming from a binary black hole merger.  At LIGO, the detection has revealed not merely a black hole merger, but also the alignment of the spins of the black holes. This can shed light on the way the black holes might have formed.

LIGO: The Laser Interferometer Gravitational-Wave Observatory is a large-scale physics experiment and observatory with the mission to directly observe gravitational waves of cosmic origin.  These waves were first predicted by Einstein’s general theory of relativity in 1916.  Their existence was indirectly confirmed when observations of the binary pulsar PSR 1913+16 in 1974. The Nobel Prize in Physics 1993 was awarded to Hulse and Taylor for this discovery. Two large observatories were built in the United States with the aim of detecting gravitational waves by laser interferometry.


LIGO-India, or INDIGO, is a planned collaborative project between the LIGO Laboratory and the Indian Initiative in Gravitational-wave Observations (IndIGO) to create a world-class gravitational-wave detector in India. A site in the Hingoli district (Maharashtra) has been selected.


NASA Missions

NICER: NASA will launch the world’s first mission devoted to studying rapidly spinning neutron stars. Neutron stars are the remnants of massive stars that, after exhausting their nuclear fuel, exploded and collapsed into super-dense spheres about the size of New York City. Although neutron stars emit radiation across the spectrum, observing them in the energetic X-ray band offers the greatest insights into their structure and the high-energy phenomena that they host, including starquakes, thermonuclear explosions, and the most powerful magnetic fields known in the cosmos.

Sounding Rocket: NASA is set to launch a sounding rocket which will release blue-green and red artificial clouds.

  • keratitis

Scientists at the Hyderabad-based CSIR-Centre for Cellular and Molecular Biology (CSIR-CCMB) have developed a novel way to treat fungal keratitis. Treating keratitis infection is currently a challenge because it is difficult to maintain a therapeutic dose at the corneal surface for long periods as blinking and tear formation washes off the drug. To address this challenge, scientists have developed protein-based nanoparticles that encapsulate the drug.

Keratitis is the inflammation of the eye, which starts with redness and itching and might eventually lead to blindness. Keratitis can be caused by both bacteria and fungi. Fungi attach themselves to the cornea and release enzymes that break down the corneal proteins for their nutritional requirements.

In the process the cornea also gets inflamed. Corneal damage causes wound and scar formation leading to severe visual impairment. It is estimated that about 30% of keratitis cases in India lead to blindness.


  • China has unveiled the world’s first train that runs on virtual tracks. The new train is part of China’s attempts to develop “intelligent rail express system”.


  • WHO has revised antibiotics protocol to curb antibiotic resistance. This is the biggest revision of the antibiotics section in the essential medicines list (EML). WHO has divided the drugs into three categories — access, watch and reserve.

The ‘access’ category includes commonly used antibiotics. They will be available at all times as treatment for a wide range of common infections.

The ‘watch’ group covers antibiotics that are recommended as first or second choice treatment for a small number of infections. Prescription of these drugs should be reduced to avoid further development of resistance.

The ‘reserve’ category includes antibiotics that are considered last-resort options, and used only in the most severe circumstances such as for life-threatening infections due to multidrug-resistant bacteria.

Importance  The new list will help health system planners and doctors ensure that people who need antibiotics have access to them, and they get the right one, so that the problem of resistance doesn’t get worse.




Plants have evolved to endure drought stress with morphological, physiological, and biochemical adaptations: 1. Drought resistance (DR) is a broader term applied to plant species with adaptive features which enables plants to escape, avoid and tolerate drought stress. 2. Drought escape (DE) is the ability of a plant species to complete its life cycle before the onset of drought. Thereby, plants do not experience drought stress, as they are able to modulate their vegetative and reproductive growth according to water availability. Eg rapid plant growth during wet season and little growth during the dry season. 3. Drought avoidance (DA) involves the ability of plants to maintain relatively higher tissue water content, despite the water scarcity in the soil (saving for a deficit day).

Drought tolerance (DT) involves the plant enduring low water content on its tissues through various adaptive traits.



Researchers in Hyderabad based LV Prasad Eye Institute (LVPEI) have successfully grown miniature eye-like organs that closely resemble the developing eyes of an early-stage embryo. These were produced using induced pluripotent stem (iPS) cells. Stem cells of a healthy eye have been used for restoring vision when only one eye is damaged. But when the damage is present in both eyes, the only way to restore vision is by using the healthy cells taken from a related or unrelated donor. Patients have to be on immune suppressants lifelong when cells are transplanted from donors. However, immune suppressants are not required when corneal cells grown using the patient’s own skin cells are used for restoring vision. Immuno suppressants are a class of drugs that suppress the immune response through various mechanisms. In organ transplantation, they are used to prevent the body from either recognition or attacking the foreign organ.

A disease that was known for its presence only in urban areas gradually spread across the country. According to the National Vector Borne Disease Control Programme (NVBDCP) In 2016, the number of cases were 1,29,166 and 245 deaths.



A Study at DNA Fingerprinting and Diagnostics, Hyderabad has come up with new insights on Leukemia.

What is Leukemia?

 Leukemia is cancer of the blood or bone marrow which produces blood cells. A person who has leukemia suffers from an abnormal production of blood cells.Acute leukemia crowds out the good cells more quickly than chronic leukemia. Treatment requires holistic approach of financial support, psychological support and a patient trackingsystem.

What is the status of leukemia in India?

 Acute leukemia cases are recorded across India. There are nearly 25,000 children diagnosed with cancer in India every year and around 9000 of these haveleukemia. There would be 90,000 children with leukemia in a decade in India. The data of those children who are treated are missing.

What are the findings of the study?

 Mixed Lineage Leukemia (MLL) protein is closely associated with leukemia (blood cancer) in children and   adults.  The protein plays a crucial role in cell division by regulating chromosome segregation.The absence of MLL itself gives rise to genomic instability and makes the cell prone to cancer.Efforts has been made to discover the essential cellular functions of MLL.

Scientists have developed the  sharpest laser with record-breaking precision that can help make optical atomic clocks more precise as well as test Einsteins theory of relativity.

Ideally, laser light has only one fixed wavelength or frequency. In practice, the spectrum of most types of lasers can, however, reach from a few kHz to a few MHz in width, which is not good enough for numerous experiments requiring high precision. Researchers have now developed a laser with a linewidth of only 10 miliHertz (mHz) — closer to the ideal laser than ever before.

Significance of this discovery: This precision is useful for various applications such as optical atomic clocks, precision spectroscopy, radioastronomy and for testing the theory of relativity.

  • Debug Fresno (California USA)

The project, called Debug Fresno, is being undertaken by Verily, a subsidiary of Alphabet, Google’s holding company. The goal is to cut the numbers of Aedesaegypti mosquitoes — the species responsible for spreading zika, dengue and chikungunya. For 20 weeks, the company plans to release a million of the sterile, non-biting male mosquitoes in two neighbourhoods in Fresno county. The male mosquitoes are bred and infected with Wolbachia, a bacterium that is naturally found in at least 40% of all insect species.In a phenomenon called cytoplasmic incompatibility, matings between Wolbachia-infected males and uninfected females result in embryo lethality or low hatch rates.



In a first, scientists have produced human antibodies in the laboratory using a technique that could usher the rapid development of new vaccines to treat a wide range of infectious diseases. Antibodies are produced by the body’s B cells to fight off infections by bacteria, viruses, and other invasive pathogens. When an individual B cell recognises a specific pathogen-derived “antigen” molecule, it can proliferate and develop into plasma cells that secrete large amounts of antibody capable of binding to the antigen and fending off the infection. Note: antigen is toxin.

About the new technique:

In addition to encountering a specific antigen, B cells need a second signal to start proliferating and developing into plasma cells. Researchers provided this second signal by short DNA fragments called CpG oligonucleotides, which activate a protein inside B cells named TLR9.


  • The Double Asteroid Redirection Test (DART)

Is being designed and would be built and managed by the John Hopkins Applied Physics Laboratory is moving from concept development to preliminary design phase. DART would be NASA’s first mission to demonstrate what’s known as the kinetic impactor technique – striking the asteroid to shift its orbit – to defend against a potential future asteroid impact. The target for DART is an asteroid that will have a distant approach to Earth in October 2022, and then again in 2024. The asteroid is called Didymos– Greek for “twin” -because it is an asteroid binary system that consists of two bodies: Didymos A, about 780 metres in size, and a smaller asteroid orbiting it called Didymos B, about 160 metres in size. ART would impact only the smaller of the two bodies, Didymos B.



Scientists have successfully encoded a movie in the DNA of a living cell, where it can be retrieved at will and multiplied indefinitely as the host divides and grows. It is the latest and perhaps most astonishing example of the genome’s potential as a vast storage device. they used a powerful new gene editing technique, Crispr, to slip this sequence into the genome of a common gut bacteria, E. coli.Despite the modification, the bacteria thrived and multiplied. The film stored in the genome was preserved intact with each new generation of progeny.



  • THE CORONA: nanoflares

The corona is heated to millions of degrees, yet the lower atmospheric layers like the photosphere – the visible surface of the Sun – are only heated to a few thousand degrees. Scientists are not sure how this inversion happens. One theory proposes micro explosions, termed nanoflares – too small and frequent to detect individually, but with a large collective effect – might release heat into the coronaThe corona is the outermost layer of the Sun, starting at about 1300 miles (2100 km) above the solar surface (the photosphere). The temperature in the corona is 500,000 K (900,000 degrees F, 500,000 degrees C) or more, up to a few million K. The corona cannot be seen with the naked eye except during a total solar eclipse, or with the use of a coronagraph. The corona does not have an upper limit.


  • National Payments Corporation of India (NPCI),

  • CubeSats:

With rapid developments in miniaturisation of technologies CubeSats — which typically weigh about two kilograms — are poised to take over the sky in the future to carry out tasks like imaging and remote-sensing currently performed by heavier satellites which are expensive to build and launch. However, today’s CubeSats cannot totally replace their larger counterparts as they are incapable of changing orbit or performing complex manoeuvres.

new propulsion system:

A dedicated propulsion system that is also compact and not power hungry has been the aim of CubeSat builders in several laboratories to exploit their full potential. Called a “Film-Evaporation MEMS Tunable Array”, or FEMTA thruster, it uses capillaries thinner than human hair through which the propellant water can flow. Small heaters located near the ends of the capillaries turn the water into vapor, which, on escape from these tiny tubes, provides the thrust. The minuscule capillaries act like valves that can be turned on and off by activating the heaters.


  • the new state- ELECTRONIC NEMATIC STATE:

The high-magnetic-field state of the heavy fermion superconductor CeRhIn5 revealed a so-called electronic nematic state. In the new state, the material’s electrons are aligned in a way to reduce the symmetry of the original crystal, something that now appears to be universal among unconventional superconductors. The appearance of the electronic alignment, called nematic behavior, in a prototypical heavy-fermion superconductor highlights the interrelation of nematicity and unconventional superconductivity, suggesting nematicity to be common among correlated superconducting materials.


A nematic state is most well known in liquid crystals, wherein the molecules of the liquid are parallel but not arranged in a periodic array. Nematic-like states have been observed in transition metal systems near magnetic and superconducting phase transitions. The occurrence of this property points to nematicity’s correlation with unconventional superconductivity. The difference, however, of the new nematic state found in CeRhIn5 relative to other systems is that it can be easily rotated by the magnetic field direction.


  • Karnataka has launched the much-touted cloud seeding project- named Varshadhare.

The biofuel cells are equipped with an enzyme that oxidises the lactic acid present in human sweat to generate current.


  • Researchers at the Indian Institute of Technology (IIT) Guwahati have successfully created an implantable bioartificial pancreas model grown within a 3D silk scaffold. The pancreas encapsulates insulin-producing cells and is capable of naturally producing insulin in a sustained manner.

How was it created?

Scientists coated the scaffold containing beta cells with a semi-permeable membrane barrier. The membrane allows insulin produced to be released into the blood stream but does not allow the immune cells to cross the membrane and kill the islet cells. To ensure that the implant is not rejected by the body’s immune system, drugs that suppress the immune system were embedded in the scaffold.

If successful in animal and human trials, it can be used for treating people with type 1 diabetes. Type 1 diabetes arises when the body  immune system kills the insulin-producing beta cells. Since type 1 diabetes patients do not have insulin-producing beta cells, the researchers have turned to stem cells to produce beta cells.



  • The Indian Space Research Organisation (ISRO) says it plans to launch a full-fledged niche Earth observation (EO) satellite — called the Hyperspectral Imaging Satellite or HySIS — using a critical chip it has developed. With this satellite, it can see in 55 spectral or colour bands from 630 km above ground.

What is Hyspex imaging?

Hyspex’ imaging is said to enable distinct identification of objects, materials or processes on Earth by reading the spectrum for each pixel of a scene from space. ISRO first tried it out in an 83-kg IMS-1 experimental satellite in May 2008. The same year, a hyperspectral camera was put on Chandrayaan-1 and used to map lunar mineral resources. Very few space agencies have such a satellite;

A German environmental satellite called EnMAP is due to be launched on an Indian booster in 2018.


Hyperspectral or hyspex imaging is said to be an EO trend that is being experimented globally. Adding a new dimension to plain-vanilla optical imagers, it can be used for a range of activities from monitoring the environment, crops, looking for oil and minerals all the way up to military surveillance — all of which need images that show a high level of differentiation of the object or scene.


  • China has demonstrated a world first by sending data over long distances using satellites which is potentially unhackable, laying the basis for next generation encryption based on so-called quantum cryptography. Last year, China launched a quantum satellite into space. Using this satellite, Chinese researchers at the Quantum Experiments at Space Scale (QUESS) project, were now able to transmit secret messages from space to Earth at a further distance than ever before.

The technology is called quantum key distribution (QKD). Typical encryption relies on traditional mathematics and while for now it is more or less adequate and safe from hacking, the development of quantum computing threatens that. Quantum computing refers to a new era of faster and more powerful computers, and the theory goes that they would be able to break current levels of encryption. QKD works by using photons — the particles which transmit light — to transfer data.

QKD allows two distant users, who do not share a long secret key initially, to produce a common, random string of secret bits, called a secret key. Using the one-time pad encryption this key is proven to be secure to encrypt and decrypt a message, which can then be transmitted over a standard communication channel.

The encryption is “unbreakable” and that’s mainly because of the way data is carried via the photon. A photon cannot be perfectly copied and any attempt to measure it will disturb it. This means that a person trying to intercept the data will leave a trace. Any eavesdropper on the quantum channel attempting to gain information of the key will inevitably introduce disturbance to the system, and can be detected by the communicating users.



  • Project Brainwave

Software giant Microsoft has announced its Project Brainwave deep learning acceleration platform for real-time artificial intelligence (AI). The ‘Project Brainwave’ uses the massive field-programmable gate array (FPGA) infrastructure that Microsoft has been deploying over the past few years. With the help of ultra-low latency, the system processes requests as fast as it receives them. The system architecture reduces latency, since the CPU does not need to process incoming requests, and allows very high throughput, with the FPGA processing requests as fast as the network can stream them. The system has been architected to yield high actual performance across a wide range of complex models, with batch-free execution.

Real-time AI is becoming increasingly important as cloud infrastructures process live data streams, whether they be search queries, videos, sensor streams, or interactions with users.


  • Gobindobhog rice, a speciality from Burdwan district of West Bengal, has got the geographical indication (GI) status.





 After 20 years in Space, NASA‘s Cassini Spacecraft has made its final death plunge in Saturn recently. It is a well planned demise to prevent any damage to Saturn‘s ocean bearing moons Titan and Enceladus. Cassini was launched from Cape Canaveral, Florida in 1997 and it arrived in Saturn in 2004.

 It is a joint NASA-European space agency mission. It is the fourth space probe to visit Saturn (pioneer 11, Voyager1, Voyager 2) and the first to enter orbit. Its design includes a Saturn Orbiter and a Lander called ―Huygens for the moon Titan. The European Huygens landed on Saturn‘s big moon Titan in 2005. This was the first landing ever accomplished in the outer solar system.

Black Planet

Astronomers have discovered a black planet using hubble space telescope.

It is formally called as WASP-12b, an exoplanet that reflects almost no light, making it appear essentially pitch black. It orbits its parent star WASP-12A, about 1400 light year away.Its albedo is 0.064, whereas the albedo of earth is 0.3 and moon is 0.12.

v  Astronomers working for Stephen Hawking’s Breakthrough Listen (BL) project detected a mysterious signal in a distant galaxy and termed it a possible extra-terrestrial communication which sparked a controversy. They reportedly picked up 15 fast radio bursts (FRBs) from a source unknown and are not sure if they came from neutron stars, black holes or extraterrestrial lives across the universe.

What is a fast radio burst?

In radio astronomy, a fast radio burst (FRB) is a high-energy astrophysical phenomenon of unknown origin manifested as a transient radio pulse lasting only a few milliseconds. Fast radio bursts are bright, unresolved (pointsource-like), broadband (spanning a large range of radio frequencies), millisecond flashes found in parts of the sky outside the Milky Way. Unlike many radio sources the signal from a burst is detected in a short period of time with enough strength to stand out from the noise floor.

v  Scientists are developing an ultra-thin spacecraft that can remove space debris – which potentially threaten satellites or astronauts – by enveloping junk in the Earth’s orbit and dragging it through the atmosphere, causing it to burn up. The Brane Craft, being developed by US-based Aerospace Corporation, is a flexible and less than half the thickness of a human hair.


v  In December 2016, Japan sent H-II Transfer Vehicle Kounotori 6 (HTV6) into space to deliver supplies to the ISS. The same cargo ship was also supposed to complete another mission during its return journey – clean up space debris. However, the experimental Japanese probe failed in its mission to clear space junk from the Earth’s orbit.

Incidents so far:

In 2013, Russian satellite, Blits, was damaged after colliding with debris created when China shot down an old weather satellite in 2007.

v  NASA’s Cassini has completed a final, distant flyby of Saturns’s giant moon Titan. This distant encounter is referred to informally as “the goodbye kiss” by mission engineers, because it provides a gravitational nudge that sends the spacecraft toward its dramatic ending in Saturn’s upper atmosphere.With this, the spacecraft’s mission is all set to when it enters the planet’s atmosphere and disintegrates. In its final hours, Cassini will relay as much data as it can back to Earth before it dies. NASA hopes the data collected from the final descent will allow scientists to understand more about the planet’s atmosphere and interior.



Launched in 1997, the Cassini mission — a cooperation between NASA, the European Space Agency and the Italian Space Agency — has sent back thousands of stunning images and made numerous discoveries about the ringed planet and its moons.

About Cassini Mission:

Cassini–Huygens is an unmanned spacecraft sent to the planet Saturn. Cassini is the fourth space probe to visit Saturn and the first to enter orbit. Its design includes a Saturn orbiter and a lander for the moon Titan. The lander, called Huygens, landed on Titan in 2005. The spacecraft was launched on October 15, 1997. This was the first landing ever accomplished in the outer Solar System.


v  Over 70 years after Indian astrophysicist and Nobel laureate Subrahmanyan Chandrasekhar predicted that rapidly rotating stars would emit polarised light, scientists in Australia have observed the phenomenon for the first time. Researchers from the University of New South Wales (UNSW) in Australia and University College London in the UK used a highly sensitive piece of equipment to detect the polarised light from Regulus, one of the brightest stars in the night sky. The equipment provided unprecedented insights into the star, which is in the constellation Leo, allowing the scientists to determine its rate of spinning and the orientation in space of the star’s spin axis.



In 1946, Chandrasekhar predicted the emission of polarised light from the edges of stars, prompting the development of sensitive instruments called stellar polarimeters to try to detect this effect. In 1968, other researchers built on Chandrasekhar’s work to predict that the distorted, or squashed, shape of a rapidly rotating star would lead to the emission of polarised light, but its detection has eluded astronomers until now.

Polarized light:

Optical polarisation is a measure of the orientation of the oscillations of a light beam to its direction of travel.

It is being jointly developed by the DRDO and the private sector.  The development is being done through a consortium based model, similar to that adopted for the pinaka multi-barrel rocket launch system.  The Army has not inducted any new artillery gun since the Bofors in the 1980’s.  Last year, India signed a contract for 145 M-777 Ultra-Light Howitzers from the US.





Recent Indian study finds that it is possible to forecast the outbreak of the dengue.  _Study focuses on changes in a factor called extrinsic incubation period (EIP) of the dengue virus, by taking into account daily and monthly mean temperatures different climatic zones.  _The EIP is the time taken for incubation of the virus in the mosquito.  _During this period, after the mosquito draws blood that is rich in viruses, it escapes the gut and passes through the mosquito‘s body and reaches its salivary glands.

 _Once this happens, the mosquito is infectious and capable of transmitting the virus to a human host.


What are the outcomes of the study?

 _Climatic conditions play an important role in EIP.  _Lower temperatures (17-18°C) result in longer EIPs thereby leading to decreased virus transmission.  _From 17 to 30°C, dengue transmission increases fourfold, feeding increases because of the enhanced metabolism of the mosquito, leading to shorter EIPs.  _A further increase in temperature beyond 35°C is detrimental to the mosquito‘s survival.  _There is a strong correlation between rainfall and dengue numbers, they propose an increase in breeding grounds for mosquitoes.



  • Switching over to VoLTE

With the VoLTE revolution kick started by the Reliance Jio, Indian telecom players are battling to retain their competitive position in the market.

What is VoLTE?

Voice over Long-Term Evolution (VoLTE) is a standard for high-speed wireless communication for mobile phones and data terminals. Under the earlier LTE, the infrastructure of telecom players only allows transmission of data while voice calls are routed to their older 2G or 3G networks. Thus under LTE, one cannot access the 4G data services while on a call. On the other hand, VoLTE, a technology update to the LTE protocol, allows voice calls to be packaged‘ and carried through LTE networks. This would mean 4G data accessibility even during calls.


What are the benefits of VoLTE?

 _VoLTE allows voice service being delivered as data flows within the LTE data bearer. VoLTE is an Internet Protocol Multimedia Subsystem (IMS) specification. _IMS enables a variety of services

to operate seamlessly on the network rather than having to switch to different applications for voice or video. The various benefits of VoLTE thus include:

  1. high definition voice quality, superior to the previous networks.
  2. faster, better and wider data connectivity.
  3. network would pick up 2G or 3G signals when VoLTE is unavailable, ensuring connection with both voice and data.
  4. video calls directly from the mobile number; this could avoid the necessity for applications such as Skype or Viber.
  5. asVoLTE counts voice calls as data usage, billing will be in terms of data consumption rather than minutes of usage.
  6. better battery life as battery consumption due to switching and searching for a network from 4G to 3G to place a call is not required under VoLTE.
  7. VoLTE thus facilitates a range of services such as video calling, file transfer, real time language translation and voice mail services.

What are the challenges?

 _The service might be limited to mobile phones that are equipped with software to allow VoLTE function. Also, there is a possibility for call drops in the initial stages of implementation. Due to costs and complexity involved in the infrastructure, mobile phones and telecom operators may find it hard for adopting it immediately.  _Also, the incumbent operators are still dependent on revenue from voice, making them hesitant to switch over to VoLTE.  _These factors could prove them uncompetitive in the market.  _From the consumer end, the present free voice calls under VoLTE are not sure to continue with gradual change in pricing plans in future.



  • Fourth Gravitational Wave

 A fourth gravitational wave has been detected with help from Italy-based equipment Virgo detector.

  • In order to facilitate the smooth roll-out of machine-to-machine (M2M) communications utilizing licence exempt airwaves, sectoral regulator Telecom Regulatory Authority of India (Trai) has recommended delicensing of a chunk of spectrum in a few bands.

Important recommendations made:

Allocation of spectrum: Spectrum allocation should be technology and service neutral and no separate spectrum band should be allocated exclusively for M2M services. However, in order to facilitate the smooth roll-out of M2M services utilizing licence exempt spectrum, 1 MHz of spectrum at 868 MHz (867-868) and a chunk of 6 MHz of spectrum at 915-935 MHz is recommended to be delicensed. Delicensng the V-band (57-64 GHz) on various occasions may be done on priority.

Composition of M2M apex body: Regulatory authorities whose sector would get impacted by M2M communications like Trai, Central Drugs Standard Control Organization, National Highways Authority of India, Inland Waterways Authority of India, Central Electricity Regulatory Commission etc and Ministry of Law and Justice should be members in M2M apex body formed by Department of Telecommunications (DoT).

Registration: M2M service providers should register with DoT and all access service providers and unified licence holders using licenced spectrum shall be allowed to provide M2M services. All unified licence virtual network operators shall be accordingly be allowed to provide M2M connectivity and DoT may amend the licence condition for the same.

What is M2M?

M2M is the basis for automated information exchange between machines and can impact various industry verticals like smart city, smart grid, smart water, smart transportation, smart health etc. The government has also recognized the potential of M2M and emphasized the same in National Telecom Policy 2012.



  • The government has set up a high level forum to evaluate roadmaps and formulate a strategy to adopt 5G in the country by 2020.5G is a wireless communication technology. It is the next generation mobile networks technology after 4G LTE networks.

 The final standard for 5G will be set up by the International Telecommunications Union (ITU).

Advantages of 5G

 As per the OECD (Organization for Economic Cooperation and Development) Committee on Digital Economic Policy, 5G technologies rollout will help in increasing GDP, creating employment and

digitizing the economy.

 The 5G technology will offer far greater upload and download speed available today. This will help cloud systems to stream software updates, music, and navigation data to driverless cars. In other words, it will help aid incorporate Artificial Intelligence in our lives.

 It will enable Smart devices to exchange data seamlessly providing the ecosystem for Internet of Things (IoT).


 India lacks a strong backhaul to transition to 5G. Backhaul is a network that connects cells sites to central exchange. As of now 80% of cell sites are connected through microwave backhaul, while under 20% sites are connected through fiber. The former has bandwidth issues as it uses traditional bands while the latter provides low latency and unlimited capacity (a prerequisite for 5G).

 The Indian market is yet to adapt to 4G completely and has not fully evolved to experience an AI revolution.

Way Forward

 Fiberization of Backhaul must be carried out for the smooth adoption of 5G.

 Regulatory issues must be revisited in order to overhaul the spectrum licensing regime.

 5G capable technology must be deployed on a large scale in order to prepare for its adoption.

CSIR have developed an artificial leaf that absorbs sunlight to generate hydrogen fuel from water. Mechanism  _Artificial leaf is an ultra-thin wireless device that consists of semi-conductors stacked in such a manner as to simulate the natural leaf system.  _When visible light strikes the semi-conductors electrons move in single direction thus producing electric current which almost instantaneously splits water into hydrogen.  _A palm size artificial leaf can produce six litres of hydrogen fuel per hour thus making it extremely environment friendly. Significance  _Artificial leaf can help provide Sustainable solutions of Hydrogen generation, as current methods of Hydrogen generation emits a lot of carbon dioxide.  _The hydrogen produced can be used to power fuel cells which give energy and their only by-product is water.  _It will boost India’s green energy development as the only input for artificial leaf is Sunlight which is abundantly available in India.  _In future a car fuelled by hydrogen generated from the artificial leaf process can become a reality thus paving the way for Greener transport solutions in India. Bionic Leaf uses solar energy to split water molecules into oxygen and hydrogen, and hydrogen-eating bacteria to produce liquid fuels from CO2.


  • Kyasanur Forest Disease (KFD) or “monkey fever”,

Scientists have traced the source of a re-emerging disease, Kyasanur Forest Disease (KFD) or “monkey fever”, to cashew plantations in Goa. What is monkey fever?  _It is caused by Kyasanur forest disease virus (KFDV), a member of the virus family Flaviviridae, which also causes yellow fever and dengue.  _It was first detected in 1957 in Shimoga, Karnataka and is endemic to South Asia.  _Monkey fever is so named because it primarily affects black-faced langurs and red-faced bonnet monkeys and result in death. Even when the monkey dies still the KFD virus gets transmitted through ticks thriving on monkeys.  _The Hard ticks (Hemaphysalisspinigera) are the reservoir of KFDV. These ticks are known to thrive in the Western Ghats and transmit the disease to humans.

Nobel prize 2017

Rainer Weiss, Barry C. Barish‘s and Kip Thorne‘s were jointly awarded the Nobel Prize for physics for their contribution to the LIGO-VIRGO project and its detection of gravitational waves. What is project about?

Research – Laser Interferometer Gravitational Wave Observatory – LIGO was built in the US to detect gravitational waves.In collaboration with Italy based VIRGO observatory, LIGO detected gravitational waves for the first time in 2015. Since then, the LIGO-VIRGO collaboration has detected such signals four times.

Significance – The first detection made in 2015 revealed the merger of two black holes – 1.3 billion years ago.

 Hence, gravitational wave observations could unravel many more mysteries pertaining to the early days of the universe‘s existence.

 Gravitational wave astronomy is hence a science of the near future whereby black holes, neutron stars may be mapped.

 The advantage of having multiple detectors is that the location of the source can be determined more accurately.  More observatories are in the pipeline to add to the current 3 of which 2 belongs to LIGO & 1 to VIRGOThe Japanese KAGRA detector is set to go online in 2019 and LIGO India set to join by 2024.


Jeffrey C. Hall, Michael Rosbash & Michael W. Young are to be jointly awarded the 2017 ―Nobel Prize for Medicine. The award is for their work in discovering the mechanisms controlling the internal clocks in living organisms.

What is their research about?

 The trio‘s work was in ‗Chrono Biology‘ – A science that examines periodic phenomena in living organisms in relation to nature.  They made significant contributions in unravelling the genetic coding and protein pathways that regulate the circadian rhythm.  This rhythm is what tells us when it is time to eat, sleep or wake up – even when we have no bedside alarm.


What were the achievements of the trio?

 Isolation of a gene called Period

in fruit-flies that disrupted its circadian clock was the most important achievement.

PER – A protein named ‗PER‘ that serves as a functional communicator for the ‗Period Gene‘ was discovered.  PER was found to accumulate at night & diminish during the day.

Timeless – A second gene called ‗Timeless‘ that acts through its ‗TIM protein‘ in conjunction with ‗PER‘ was also identified.

 This was found to cause the seesawing of cellular protein levels.

Doubletime – A third gene called ‗Doubletime‘ was discovered to be the regulator of the frequency of the oscillations.


Richard.H.Thaler, an American received Nobel Prize for his behavioural Economic theory. What are the bases of economic theories?

 Most economic theories are based on a certain set of assumptions without which it would be difficult to talk in a coherent fashion about any theory; these assumptions simplify the complex everyday reality.

 So an economic model could assume that economic agents have perfect information or that the transaction costs are zero.

 In a similar vein, one of the dominant assumptions has been about economic agents being rational.

 That is to say, they only act in self-interest, but often  there are gaps between the behaviour as predicted by the model and as it is in reality.


What is the finding of Thaler?

 He has refined economic analysis by taking into account three psychological traits

Limited rationality – It underlines that it is not realistic to assume that individuals could be completely rational and think of all possible effects of their choices.

 Thaler built on this insight to come up with his theory of mental accounting, which describes how people organise, formulate and evaluate financial decisions.

 For instance, this tendency to create separate mental accounts for day-to-day expenses and holiday expenditure explains why individuals might not dip into their long-term savings and instead use a credit card to tide over some imbalances in daily expenses.

Perceptions about fairness – Full rationality assumption of traditional theories cannot explain behaviour when it deviates to accommodate an individual‘s sense of fairness.

 Through large experiments, Mr Thaler shown how people can set aside personal gain and concern themselves with questions of fairness.

 For instance, Consumers judge negatively a company which is seen to be unjustly raising prices in times of pressure.

Lack of self-control – Actual human behaviour has shown that people may, contrary to notions of rationality, choose something that goes against their interest.

 For instance, a smoker who chooses to yield to an immediate temptation instead of favouring better health in the longer term.


Why Thalers contribution is significant?

 His contribution goes to the very heart of economic modelling and has a profound impact on many areas of economic research.

 Since field of economics concerns itself with how human behaviour explains the deviations from the established theoretical model, it has wide-ranging impact.

 Studying the so-called ―irrationalities has implications for

1. Financial behaviour – Something like unjustified market volatility

2. Marketing – The ―buy two get one free schemes providing a sense of having gained.

3. Public policy making – Wherein politicians ―nudge individuals towards a societal improvement.

  • Two Teams from IIT Hyderabad and IIT Bombay are working on achieving promising results on skin cancer Nanoparticle formulation of a chlorophyll-rich biomolecular extract of an Indian medicinal plant Anthocephalus cadamba combined with a near-infrared dye has been found to selectively kill skin cancer cells. The plant extract is toxic to cancer cells as there is enhanced generation of reactive oxygen species (ROS) while the dye aids in the destruction of cancer cells through photothermal therapy. On being irradiated with near-infrared light, the dye gets heated up and facilitates the release of the extract from polymer membrane. After 4-5 minutes of irradiation, about 80% of cancer cells were killed


  • Scientists in India have discovered a 152 million-year-old fossil of an Ichthyosaur – an extinct marine reptile – in the western state of Gujarat.The fossil (5.5 m) was found inside rocks from the Mesozoic Era, which ran between 252 and 66 million years ago, in the Kutch desert.

Specimen can be identified with Ophthalmosauridae, a family of ichthyosaurs that lived in the oceans between 165 and 90 million years ago.

Ichthyosaur: Often misidentified as “swimming dinosaurs”, they first appeared in the early Triassic period. The name means fish-lizard, although the creature has been classified as a reptile since the mid-19th Century.The creature was noted for its sharp, robust teeth. Ichthyosaurs became extinct before the dinosaurs, dying out in the early part of the late Cretaceous period .

Space Activities Bill 2017

The government of India has come up with Space Activities Bill 2017, a draft law meant to regulate the space sector.


Department of Space(DoS) is the nodal agency for space activities in India which include:

o Space Infrastructure: spacecraft for various applications and associated ground infrastructure

o Space Transportation systems: various class of launch vehicles and associated ground infrastructure Space applications: for various national requirements through establishment of necessary ground infrastructure and coordination mechanisms.

 Space activities in India till now have been governed by Satellite Communication Policy, 2000 (which enacted a framework to provide licenses to private sector players to operate communication satellites over India) and the Remote Sensing Data Policy, 2011.

 However apart from these two policies, there has been no formal law in the country that provided any framework for creating a private space venture.

 Internationally, the outer space activities are governed by relevant chapters of international law in general and by United Nations’ (UN) Treaties and principles evolved under UN Committee on Peaceful Uses of Outer Space (UNCOPUOS) in particular


Need for a Space Law

 There has been a growing interest of private sector in the space activities with startups like TeamIndus, Bellatrix Aerospace and Astrome Technologies planning their own space-based products and services.

 The involvement of the emerging private sector becomes crucial as the current manpower of ISRO is not sufficient to meet the increasing demands of satellite launches.

 ISRO has been trying to build the private industrial capabilities in the country to support its activities. Recently, it invited single or combined bids from private players to build up to 18 spacecraft a year.

 But apart from Satellite communication and Remote Sensing Policy, there has been no formal law in the country that provided any framework for creating a private space venture.

 The new Bill encourages the participation of private sector agencies in space activities in India under the guidance and authorisation of the government through the Department of Space.


Salient Features of the Draft Law

 The provisions of this Act shall apply to every citizen of India and to all sectors engaged in any space activity in India or outside India.

 A non-transferable licence shall be provided to any person carrying out commercial space activity through an appropriate mechanism.

 The government will maintain a register of all space objects (any object launched or intended to be launched around the earth).

 It will provide professional and technical support for commercial space activity and regulate the procedures for conduct and operation of space activity through a regulatory body.

 If any person undertakes any commercial space activity without authorisation they shall be punished with imprisonment up to 3 years or fined more than ₹1 crore or both.



Erroneous Definition of Space Activity – As per the definition of space activity in the bill even data companies handling satellite imagery or universities operating ground facilities for their microsatellites may also need a licence. This might adversely affect the operations of hardware and internet companies.


Non-specification of Regulator – As the bill hasn’t specified an independent regulator for the space sector, making DoS the regulator will amount to conflict of interest because DoS is also a service provider through ISRO as well as a commercial operator through Antrix.

One Blanket Law for All Space Activities – Space activities have not been segregated and putting them all under one blanket licence can hinder their efficient functioning.

Non-differentiation of Liabilities – The liabilities of upstream activities such as spaced operations and launch and those of downstream activities such as space-based products/services on the ground are different. However, it hasn’t been defined separately and has been passed on to the players involved.

Non-clarity on Pollution – Pollution to the environment of outer space including celestial bodies has not been defined clearly.



Scientists have recently discovered the most ancient spiral galaxy in the universe that existed 11 billion years ago.  The discovery was made by Australian National University  (ANU) and Swinburne University of Technology using a technique that combines gravitational lensing with the Near-infrared Integral Field Spectrograph (NIFS).  The galaxy, known as A1689B11, existed just 2.6 billion years after the Big Bang, when the universe was only one fifth of its present age.  In a spiral galaxy, the stars, gas and dust are gathered in spiral arms that spread outward from the galaxy’s center.   Spiral galaxies are exceptionally rare in the early universe, and this discovery opens the door to investigating how galaxies transition from highly chaotic, turbulent discs to tranquil, thin discs like those of our own Milky Way galaxy





Small, collaborative robots, or cobots, are gaining currency across the world, as also in India. Several firms, be it Bajaj Auto or Aurolab, have benefited from the adoption of cobots and are planning to add more to their shop floors.

What is a cobot?

A cobot is intended to work hand-in-hand with humans in a shared workspace. This is in contrast with full-fledged robots that are designed to operate autonomously or with limited guidance. They support and relieve the human operator of his excess work.

Benefits of Cobots:

Cobots are easy to use, flexible and safe. Unlike industrial robots, cobots don’t need fencing for the protection of workers in the shop floor.


  • researchers at the Columbia University Medical Center (CUMC) in the U.S. have modified an ordinary laboratory strain of human gut microbe Escherichia coli into the world’s smallest data recorder. Researchers have converted this natural bacterial immune system enabling the bacteria to not only record their interactions with the environment but also time-stamp the events.

How was it created?

Researchers created the microscopic data recorder by taking advantage of CRISPR-Cas, an immune system in many species of bacteria. CRISPR-Cas copies snippets of DNA from invading viruses so that subsequent generations of bacteria can repel these pathogens more effectively.

As a result, the CRISPR locus of the bacterial genome accumulates a chronological record of the bacterial viruses that it and its ancestors have survived. When those same viruses try to infect again, the CRISPR-Cas system can recognise and eliminate them.

Potential applications:

This discovery has formed the groundwork for a new class of technologies that use bacterial cells for everything from disease diagnosis to environmental monitoring. Such bacteria, swallowed by a patient, might be able to record the changes they experience through the whole digestive tract, yielding an unprecedented view of previously inaccessible phenomena.

Other applications could include environmental sensing and basic studies in ecology and microbiology, where bacteria could monitor otherwise invisible changes without disrupting their surroundings.

Recently, scientists have discovered a new species of parasitic plant and named it Gleadovia konyakianorum, after the Naga Tribe Konyak.

About the new plant

 It has been found in the semi evergreen forest of Nagaland at  an altitude of 1500-1600m above the sea level.   It grows up-to a height of 10cm and has yellow leaves and  white tubular flowers.

 It is a holoparasite which doesn’t have chlorophyll but has a  well-developed vascular system.

 It extracts nutrition with the help of haustorium (a specialised  structure with which the parasite attaches itself to the tissue of  host plant and derive nutrition) from Strobilanthes plants growing on the bank of streams.

The main threat to this species of parasitic plant is habitat destruction caused by illegal felling of trees.

The International Union for Conservation has described its status as ‘data deficient’ as the species have not been reported anywhere else.

 The other three species of Gleadovia genus are found in Manipur, Uttarakhand and China

Parasites are the organisms which live in or on other organisms and survive by deriving nutrients from the host. Types of Parasites:

Holoparasite – are those which depend completely on the host for their nutritional needs.

Hemiparasites – are those which are capable of both photosynthesis and parasitism.

  • The Telecom Regulatory Authority of India (TRAI) has come out in strong support of Net neutrality in a series of recommendations following a long process of consultations on the issue.

The recommendations assume international significance in the heated globe-spanning debate, with the United States’ Federal Communications Commission expected to remove existing guidelines ensuring net neutrality come December.




Kepler 90i

NASA has recently announced that it found another solar system with 8 planets. The historic discovery was made by new scientific analysis of data obtained by the Kepler space telescope. Kepler 90 is the first star to host as many planets as our own solar system.

Use of Deep learning neural networks:

The new exoplanets have been discovered using a deep learning neural network — an artificial intelligence tool that mimics the workings of a human brain.

 Scientists “trained” their computer to analyse light readings made by NASA’s Kepler Space Telescope, which are archived and made available for anyone to use. During its mission from 2009 to 2013, the Kepler Space Telescope surveyed nearly 200,000 stars, with 35,000 possible planet signals. The network was made to learn to identify true signals using 15,000 previously vetted signals.

 They then studied the weaker signals recorded from 670 star systems that had multiple known planets orbiting them, finally coming up with this discovery. The network also identified another Earth-sized exoplanet, Kepler 80g, orbiting the star Kepler 80. This is a very stable system in which Kepler 80g and four of its neighbours are locked together in a so-called resonant chain.


What is Deep Learning?

Deep learning is a machine learning technique that teaches computers to do what comes naturally to humans: learn by example. In deep learning, a computer model learns to perform classification tasks directly from images, text, or sound. Deep learning models can achieve state-of-the-art accuracy, sometimes exceeding human-level performance. Models are trained by using a large set of labeled data and neural network architectures that contain many layers.


Deep learning is a key technology behind driverless cars, enabling them to recognize a stop sign, or to distinguish a pedestrian from a lamppost. It is the key to voice control in consumer devices like phones, tablets, TVs, and hands-free speakers. Deep learning is getting lots of attention lately and for good reason. It’s achieving results that were not possible before.

What’s the Difference Between Machine Learning and Deep Learning?

 Deep learning is a specialized form of machine learning. A machine learning workflow starts with relevant features being manually extracted from images. The features are then used to create a model that categorizes the objects in the image. With a deep learning workflow, relevant features are automatically extracted from images. In addition, deep learning performs “end-to-end learning” – where a network is given raw data and a task to perform, such as classification, and it learns how to do this automatically.

 Another key difference is deep learning algorithms scale with data, whereas shallow learning converges. Shallow learning refers to machine learning methods that plateau at a certain level of performance when you add more examples and training data to the network.

 A key advantage of deep learning networks is that they often continue to improve as the size of your data increases.


v  Earth in its yearly motion around the Sun passes through a debris trail left behind by a comet. The debris heats up at it enters Earth’s atmosphere and burns up in bright burst of light, it is called meteor shower.

Usually meteor shower happens due to the debris left behind by a Comet. However, it can happen due an asteroid as well such as in the case of Geminid Shower.  Geminid Meteor shower is the dust particle of constellation of Gemini. Earth passes through the path of 3200 Phaethon every year. 3200 Phaethon  is an Apollo Asteroid and has characteristics close to a comet. • Sometime the orbits of an asteroid intersect with the orbit of Mars and Earth. The earth orbiting asteroids are called Apollo Asteroids.

• It will provide an opportunity for India to emerge as a leader in the Indian Ocean, forging cooperation among South Asian and African countries.

• The Centre will cater to the increasing worldwide need to build technical and management capacity in marine and coastal sustainability issues as well as efficient management and response to marine natural hazards.


v  US government recently declassified information about ―Advanced Aerospace Threat Identification Program (AATI).This has revived long subdued interests in Unidentified Flying Objects (UFO) and Alien life-forms.

v  Chinese satellite which was sent to the skies to look for evidence of the annihilation or decay of dark matter particles in space has detected unexpected and mysterious signals in its measurement of high-energy cosmic rays, bringing scientists closer to proving the existence of the invisible matter. The mysterious dark matter is believed to comprise a quarter of universe.

The satellite, Dark Matter Particle Explorer (DAMPE), also called Wukong or “Monkey King”, has measured more than 3.5 billion cosmic ray particles with the highest energy up to 100 tera-electron-volts (TeV), including 20 million electrons and positrons, with unprecedented high energy resolution


v  Sentinel- 5P, a European satellite tracking the levels air pollutants around the world has beamed back new views of the Earth’s atmosphere, including images of pollution drifting away from power plants in India. The worst of this pollution runs from north of Patna in Bihar to south of Raipur in Chhattisgarh. The Sentinel-5P satellite is designed to make daily global maps of the gases and particles that pollute the air. Sentinel-5P is the latest spacecraft in a fleet of Earth observers being commissioned by the European Union and the European Space Agency. It was launched into an 824 kilometre high orbit by a Russian rocket on October 13 this year. When fully operational, the new Sentinel will be an extremely powerful tool to monitor air quality.

It carries an instrument called Tropomi – a spectrometer that observes the reflected sunlight coming up off the Earth, analysing its many different colours. This helps detect the presence of trace gases such as nitrogen dioxide, ozone, sulphur dioxide, methane, and carbon monoxide in the atmosphere.


v  NASA’s flying observatory Sofia is preparing for its 2018 campaign, which will include, among others, observations of celestial magnetic fields, star-forming regions, comets and Saturn’s giant moon Titan. This will be the fourth year of full operations for Sofia, short for Stratospheric Observatory for Infrared Astronomy, with observations planned between February 2018 and January 2019.

Significance of the observations:

Scientists believe that the observatory’s investigations will help them understand how magnetic fields affect the rate at which interstellar clouds condense to form new stars. These observations could also help them learn whether the luminosity of these active black holes is driven by star formation or accretion of material onto the central black hole. Sofia will also conduct observations to better understand how methane levels change with seasons on Mars. Water vapor blocks infrared light energy and 99% of the world’s water vapor exists below 39,000 feet. So, the higher altitude you fly, the drier it gets and the more optimal it is for infrared observation

About Sofia:

What is it? Sofia is a Boeing 747SP jetliner modified to carry a 100-inch diameter telescope. It is a joint project of NASA and the German Aerospace Centre, DLR. SOFIA is designed to observe the infrared universe.

  • X, a division owned by Google’s parent company Alphabet and one that deals in experimental technologies, has signed a MoU with Andhra Pradesh government to setup developmental centre in Visakhapatnam and to create a high speed internet network that doesn’t require special cabling.

About the project:

No cables will be used. Instead of cables, the X internet network will use “Free Space Optical Communications, aka FSOC, technology”. This network will power internet in 13 districts through 2 thousand FSOC links. The X centre in Visakhapatnam will be its first development centre outside the US.

What is FSOC technology?

FSFC is an optical communication technology that uses light to wirelessly transmit data to telecommunication and internet applications. The technology remained outside the commercial applications for long owing to distance, speed, and efficiency related problems.

How FSOC technology works?

FSOC links use beams of light to deliver high-speed, high-capacity connectivity over long distances, just like fiber optic cable, but without the cable. And because there’s no cable, this means there’s none of the time, cost, and hassle involved in digging trenches or stringing cable along poles. FSOC boxes can simply be placed kilometres apart on roofs or towers, with the signal beamed directly between the boxes to easily traverse common obstacles like rivers, roads and railways.


Less than 20% of people in Andhra Pradesh currently have access to broadband connectivity. The state government has committed to connecting 12 million households and thousands of government organizations and businesses by 2019 – an initiative called AP Fiber Grid.

About Google X:

Founded by Google in 2010 as Google X with an aim to work on finding solutions to the world’s large problems, this American semi-secret advanced technology lab facility became an independent Alphabet company and was renamed as X after Google was restructured into Alphabet in the year 2015. It has been working on several projects including driver-less car, product delivery through flying vehicles, Project Loon, Google glass among other technologies.

Recently, computers at some offices of the West Bengal State Electricity Distribution Company Limited were crippled by ‘WannaCry’ virus, a global ransomware. Ransomware is a type of malicious software designed to block access to a computer system until a sum of money is paid.

  • Scientists have developed a new type of neural network chip that can dramatically improve the efficiency of teaching machines to think like humans. The network is called- Reservoir Computing System.

How was it created?

Researchers from University of Michigan in the US created their system using memristors, which require less space and can be integrated more easily into existing silicon-based electronics. Memristors are a special type of resistive device that can both perform logic and store data.

How it works?

 Researchers used a special memristor that memorises events only in the near history. Inspired by brains, neural networks are composed of neurons, or nodes, and synapses, the connections between nodes.

 To train a neural network for a task, a neural network takes in a large set of questions and the answers to those questions. In this process of what’s called supervised learning, the connections between nodes are weighted more heavily or lightly to minimise the amount of error in achieving the correct answer.

 Once trained, a neural network can then be tested without knowing the answer. For example, a system can process a new photo and correctly identify a human face, because it has learned the features of human faces from other photos in its training set.


Significance of the system:

Reservoir computing systems built with memristors can skip most of the expensive training process and still provide the network the capability to remember. This is because the most critical component of the system – the reservoir – does not require training.

When a set of data is inputted into the reservoir, the reservoir identifies important time-related features of the data, and hands it off in a simpler format to a second network. This second network then only needs training like simpler neural networks, changing weights of the features and outputs that the first network passed on until it achieves an acceptable level of error.


The system can predict words before they are said during conversation, and help predict future outcomes based on the present.


  • bio-CNG

To promote the use of clean fuel, the oil ministry plans to set up bio-CNG (compressed natural gas) plants and allied infrastructure at a cost of Rs7,000 crore. The oil ministry will be working with state-run oil and gas retailers to set up the plants over the next two years. The government’s plan is to make India a gas-based economy.

What is Bio- CNG?

Bio-CNG is a purified form of biogas with over 95% pure methane gas. It is similar to natural gas in its composition (97% methane) and energy potential. While natural gas is a fossil fuel, bio-CNG is a renewable form of energy produced from agricultural and food waste. Bio-CNG is being looked at as an environment-friendly alternative to diesel.
