Science & Technology current affairs 2019
Following the current events and news in the area of science and technology is very very important for the general studies paper in the UPSC exam. In recent times questions are set on only those topics that have made news. Regular study of science from NCERT books or otherwise is no longer required. The idea is to follow the current affairs news related to science and technology and understand the science behind those issues. This is true for all levels of teh IAS exam - prelims, mains and also the interview.

- Chandrayaan 2: It is India's second lunar exploration mission after Chandrayaan-1. Developed by the Indian Space Research Organisation, the mission is planned to be launched to the Moon by a Geosynchronous Satellite Launch Vehicle Mark III. The Indian Space Research Organisation (ISRO) announced the launching of Chandrayaan-2,’ India’s second lunar mission’ which is scheduled to be launched between July 9th and 16th 2019. Chandrayaan-2 is India’s second lunar mission. It will be launched using India’s most powerful rocket GSLVMK-III RIN Satish Dhawan Space Centre in Sriharikota in Andhra Pradesh. It’s objective is to collect scientific information on lunar (moon) topography, mineralogy, elemental abundance, lunar exosphere and and signatures of hydroxyl and water-ice. It has three modules (a detachable self-contained unit of a spacecraft) namely Orbiter, Lander named Vikram and Rover named Pragyan.All these three modules have been made in India.
The Chandrayaan-2’s lander will touch down near Moon’s south pole on 6th September 2019.
Chandrayan-2 mission would make a soft landing on southern pole of the moon, which is still unexplored by any of the countries. This will not only be important but also historically significant as it would give ISRO the opportunity to name the site on the moon.
It is a folkloric ape-like creature taller than an average human, that is said to inhabit the Himalayan mountains. Indian Army Mountaineering Expedition to Mt Makalu claims to have discovered the footprints of snowman ‘Yeti’ the abominable snowman as it is known in legends, near the Makalu Base Camp by posting photographs of ‘ mysterious footprints’ that measure about 32×15 inches, on Twitter. But several scientists that are based at Dehradun-based Wildlife Institute of India (WII), who have worked in Nepal , also said the footprints could be those of a bear. Besides the Joint secretary of Nepal’s forest department Maheshwar Dakal said the Makalu-Barun National Park has a healthy population of the brown bear but they have no evidence that the Yeti exists in the area. ‘We cannot ascertain the presence of the Yeti unless we have the picture of yeti as a proof. The footprint does not explain all and could be of bear or snow leopard,’ Dakal said.
- IIT Madras: It is a public engineering institute that was set up in the year 1959 in Madras through an Act of Parliament. In a significant development, a research team from IIT Madras has developed a common unified script for nine Indian Languages. According to different sources, the script was developed taking cue from European languages, were several of them had the same (Roman letter–based) script. The team led by Srinivasa Chakravathy’s team at IIT Madras developed developed a unified script for nine Indian languages, named the Bharati script. The team has now gone a step further since developing the script: it has developed a method for reading documents in Bharati script using a multi-lingual optical character recognition (OCR) scheme. The team has also created a finger-spelling method that can be used to generate a sign language for hearing-impaired persons. In collaboration with TCS Mumbai, the researchers have found a way for persons with hearing disability to generate signatures using this finger-spelling technique.
Current Affairs in Science & Tech - April 2019
- Mars: It is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. NASA spacecraft has detected what's believed to be a ‘marsquake' on planet Mars. According to report from NASA, the space agency's InSight lander, which touched down on Mars in November after a seven-month journey, sensed the seismic signal on April 6. Mission scientists are still working to confirm the source of the faint trembling, though it appears to have come not from the wind or movement of the lander's robotic arm but from below the Martian surface. If confirmed, it would be the first seismic activity ever detected on Mars. 'We've been collecting background noise up until now, but this first event officially kicks off a new field: Martian seismology!' Bruce Banerdt, a geologist at NASA's Jet Propulsion Laboratory in Pasadena, California, and the principal investigator of the InSight mission, said in a statement. The 800-pound lander is parked on the Elysium Planitia, a broad, mostly rock-free plain just north of the Martian equator. The lander is designed to operate on the surface of Mars for two years, learning about the Martian interior as a way to boost our understanding of the formation of Mars and other rocky worlds, including Mercury, Venus, Earth and the moon.
- Genome Sequencing : It is the process of determining the complete DNA sequence of an organism's genome at a single time. In a bid to educate students about the usefulness of genomics, Council of Scientific and Industrial Research (CSIR) has decided to map the population diversity. According to a report, nearly 1,000 rural youth from the length and breadth of India will have their genomes sequenced by the Council of Scientific and Industrial Research (CSIR). Globally, many countries have undertaken genome sequencing of a sample of their citizens to determine unique genetic traits, susceptibility (and resilience) to disease. This is the first time that such a large sample of Indians will be recruited for a detailed study. The project is an adjunct to a much larger government-led programme, still in the works, to sequence at least 10,000 Indian genomes.
- Antibotics: They also known as antibacterials, are medications that destroy or slow down the growth of bacteria. With reports of adverse reactions after the usage of commonly-used antibiotics, the Central Drugs Standard Control Organisation (CDSCO) has now asked manufacturers to ensure that this information be made available to the general public. In a letter to drug manufacturers, CDSCO asked them to mention in leaflets inserted into drug packets or on promotional literature, information about the adverse reactions of these medicines. All of the seven formulations — antibiotics Cefotaxime, Ofloxacin and Cefixime; Tranexamic Acid, used to control bleeding; antipsychotic drug Quetiapine; anti-rheumatoid drug Sulfasalazine and the anti-epileptic medicine Sodium Valproate — have been instructed to warn patients of the new side effects. The letter was sent out by CDSCO on April 9.
- Homo luzonensis : It is an extinct species of the genus Homo. Researchers in the Philippines have discovered a species of ancient human Homo Luzonensis which was previously unknown to science. The small-bodied hominin, named Homo luzonensis, lived on the island of Luzon at least 50,000 to 67,000 years ago. The hominin—identified from a total of seven teeth and six small bones—hosts a patchwork of ancient and more advanced features. The landmark discovery, announced in Nature on Wednesday, makes Luzon the third Southeast Asian island in the last 15 years to bear signs of unexpectedly ancient human activity. Scientists have for a long, long time, felt that there is nothing Philippine islands. Homo luzonensis flips the script, and it continues to challenge the outdated idea that the human line neatly progressed from less advanced to more advanced species.
- Mitochondrial donation: It is an experimental IVF treatment involving an egg from the mother, sperm from the father and another egg from a female donor. A baby with DNA from three people has been born in Greece following this fertility treatment. The baby boy, weighing 2.9kg (6lb) was born. Both he and his mother, who is 32, are said to be in good health. The doctors behind the treatment, from Greece and Spain, said that the birth marks a historic advance – it is the first time an IVF technique involving DNA from three people has been used with the aim of addressing fertility problems. But UK experts criticised the decision to proceed with the treatment, which they said was not backed by evidence and involved unjustifiable risks.
- Stratolaunch aircraft: It is a world’s largest airplane which completed its first test flight. According to officials, the aircraft achieved its maximum speed of 189 miles per hour (302.4 km per hour). The plane developed by aerospace venture Stratolaunch (set up by the late Microsoft co-founder Paul Allen in 2011) flew for 2.5 hours over the Mojave Desert at altitudes up to 17,000 feet. The plane has a dual fuselage design and its wingspan is greater than the length of an American football field. As per the information provided on the Stratolaunch website, the test flight took off from Mojave Air and Space Port in California at 6:58 am Pacific Time (7:28 pm India time). As part of the initial flight, the pilots evaluated aircraft performance and handling qualities before landing successfully back at the Mojave Air and Space Port, Stratolaunch said in a statement. The test team conducted standard aircraft testing exercise including a variety of flight control manoeuvres to calibrate speed and test flight control systems. The Stratolaunch aircraft is designed to act as a flying launch pad for satellites and put payloads in orbit. With 117 meters wingspan and 73 meters nose-to-tail length, the company describes its aircraft as the world’s largest plane. While it does have the largest wingspan, it does not have the longest nose-to-tail length.
- Self destructive mechanism : It is new mechanism discovered by Chinese scientist. It is also known as death switch mechanism. According to officials, this mechanism will triggers infected cells to self-destruct, thus limiting the spread of the disease and keeping other parts of the plant healthy. This research can lead to a new generation of disease-resistant crops that use significantly less pesticide and are more environmentally friendly. The research was done by scientists from Tsinghua University and the Chinese Academy of Sciences' Institute of Genetics and Development Biology. Their findings were published in the journal Science. About 20 years ago, scientists discovered that plants, like animals, have robust immune systems that can protect them from pathogens including viruses, fungi, bacteria and parasites.
- Global Cooling Coalition : It is a new coalition launched at the first Global Conference on Synergies between the 2030 Agenda and Paris Agreement held at Copenhagen, Denmark. It is supported by the UN, Climate and Clean Air Coalition, the Kigali Cooling Efficiency Program and Sustainable Energy for All (SEforALL). This coalition includes environment ministers from Chile and Rwanda and foreign affairs from Denmark as well as heads of Danish engineering firms ENGIE and Danfoss and leaders from civil society, research and intergovernmental institutions. The Global Cool Coalition is a unified front that links action across the Kigali Amendment, Paris Agreement and Sustainable Development Goals.

JNU and BHU also found the place in the list at seventh and tenth positions respectively.
- Spacex Falcon : It is the most powerful and reusable heavy-lift launch vehicle designed and manufactured by SpaceX launches the world first commercial mission. The launch is considered as a key demonstration for billionaire entrepreneur Elon Musk's space company in the race to grasp lucrative military launch contracts. Roughly three minutes after clearing the launch pad, Falcon Heavy's two side boosters separated from the core rocket for a synchronised landing at the Cape Canaveral Air Force Station, just like it did for the rocket's debut last year. The middle booster, after pushing the payload into space, returned nearly 10 minutes later for a successful landing on SpaceX's seafaring drone ship waiting 645 kilometres off the Florida coast. A successful lift-off with Falcon Heavy's new military-certified Falcon 9 boosters was a crucial element in the race against Boeing-Lockheed venture United Launch Alliance and Jeff Bezos' Blue Origin to secure lucrative military contracts. Musk's SpaceX, working to prove the flight-worthiness of its rocket fleet one mission at a time, aims to clinch one-third of all US National Security Space missions — coveted contracts that are worth billions of llars. The US Air Force tapped SpaceX in 2018 to launch a classified military satellite, which cost it USD 130 million and in February added three more missions in a USD 297 million contract.
- Cafe Scientifique: It is a new initiative aimed making science relevant, powerful and important to the public. It is promoted by a group of science experts of the Hume Centre for Ecology and Wildlife Biology. It is targeted at younger generations. Various topics such as universe, climate change, evolution, genetics and human-animal relations will be discussed in every monthly gathering.CK Vishnudas an ornithologist and director of the centre said, 'first such initiative in the State, envisages to bring science back into popular culture by demystifying scientific research for the public and empowering non-scientists to comfortably assess science and technology issues, particularly those that impact social policy making. We are planning to organise meetings of science enthusiasts in the district every month at a café or a convenient place, where one or more scientists are invited to talk to the public about new developments in science.
- 5G : It is the latest generation of cellular mobile communications. It succeeds the 4G (LTE-A, WiMax), 3G (UMTS, LTE) and 2G (GSM) systems. 5G performance targets high data rate, reduced latency, energy saving, cost reduction, higher system capacity, and massive device connectivity. South Korea launched the world’s first nationwide 5G mobile networks. Three top telecom providers of the South Korea namely SK Telecom, KT and LG Uplus have begun their 5G services two days ago. Hyper-wired South Korea has long had a reputation for technical prowess, and Seoul had made the 5G rollout a priority as it seeks to stimulate stuttering economic growth. Along with the United States, China and Japan, South Korea had been racing to claim the title as the first to provide the ultra-fast network nationwide. Experts say 5G will bring smartphones near-instantaneous connectivity -- 20 times faster than 4G -- allowing users to download entire movies in less than a second. The technology is crucial for the future development of devices such as self-driving vehicles and is expected to bring about USD 565 billion in global economic benefits by 2034, according to the London-based Global System for Mobile Communications, an industry alliance.

Also, in case of no communication from Drugs Controller General of India, the application will be deemed to have been approved. As per the new rule the requirement of a local clinical trial may be waived for approval of a new drug if it is approved and marketed in any of the countries (EU, UK, Australia, Japan and US) specified by the Drugs Controller General with the approval of the government. The new rules will ensure patient safety and an ethics committee will monitor the trials and decide on the amount of compensation in cases of adverse events. Meanwhile, the Indian Society for Clinical Research (ISCR) said that the new Clinical Trial Rules are well balanced and will further the conduct of ethical and quality clinical trials in the country which, in turn, will benefit patients.
- Indian Space Research Organisation (ISRO): It is the space agency of the Government of India headquartered in the city of Bengaluru. ISRO will launch 29 satellites including the primary payload EMISAT, on the first of April. Polar Satellite Launch Vehicle, PSLV-C45 will take off from Satish Dhawan Space Centre in Sriharikota tentatively at 9:30 AM carrying the satellites onboard. EMISAT has been developed for monitoring radar network by India. An ISRO release says, EMISAT, weighing 436 kg, is intended for electromagnetic spectrum measurement. It will be placed in an orbit of about 753 km altitude. The customer payloads are from Lithuania, Spain, Switzerland and the US. They will be hurled into space at an altitude of about 505 km. After all the satellites are put into orbits, the fourth stage of the rocket will be propelled to a different elevation and will be used as a platform for different experiments by Indian institutions, including ISRO. Indian Institute of Space Science (IISc) and the Radio Amateur Satellite Corporation are the other two institutions that will have their devices on the experimental platform. Normally the rocket engine is left redundant as space debris once the launch mission is over. But ISRO uses it for such experiments for the second time in a series. During the last PSLV mission also it adopted the same innovative method.
- Bennu: It is a carbonaceous asteroid in the Apollo group discovered by the LINEAR Project on 11 September 1999. It is a potentially hazardous object that is listed on the Sentry Risk Table with the second-highest cumulative rating on the Palermo Technical Impact Hazard Scale. NASA scientists have found water, particles in Asteroid Bennu. NASA's OSIRIS-Rex mission found plumes erupting from the cosmic body’s surface — among a numerous other findings including evidence of water-bearing minerals. NASA spacecraft which will be returning to earth would be bringing a sample of asteroid in 2023. Bennu also revealed itself to be more rugged than expected, challenging the mission team to alter its flight and sample collection plans, due to the rough terrain. Bennu is the target of NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (Osiris-REx) mission, which began orbiting the asteroid on December 31 last year. Bennu, which is only slightly wider than the height of the Empire State Building, may contain unaltered material from the very beginning of our solar system. Speaking on the development ante Lauretta, Osiris-REx principal investigator at the University of Arizona said, ' The discovery of plumes is one of the biggest surprises of my scientific career. And the rugged terrain went against all of our predictions. Bennu is already surprising us, and our exciting journey there has just getting started.

- Indian Space Research Organisation (ISRO): It is the space agency of the Government of India headquartered in the city of Bengaluru. Its vision is to "harness space technology for national development while pursuing space science research and planetary exploration. ISRO is planning to launch an exclusive satellite for the home ministry to help it further strengthen its frontiers with Pakistan and Bangladesh among others. According to an official statement issued, the move is part of recommendations made by a task force on the use of space technology in improving border management which have been accepted by home minister Rajnath Singh. To execute the project in a time bound manner, a short, medium and long-term plan has been proposed for implementation in five years in close coordination with the ISRO and the defence ministry. Major recommendations of the report are to build capacity in border guarding forces to use space resources for security, operational planning and border infrastructure development. In short term, immediate needs of border guarding forces will be met by procurement of high resolution imagery and hiring of bandwidth for communications. In mid-term, one satellite is being launched by the ISRO for exclusive use of the MHA. ISRO's Polar Satellite Launch Vehicle (PSLV-C44)successfully injected Microsat-R andKalamsat-V2 satellites into their designated orbits. Microsat-R was successfully injected into intended orbit of 274 km. After injection, two solar arrays of the satellite were deployed automatically and ISRO Telemetry Tracking & Command Network (ISTRAC) at Bengaluru assumed control of the satellite. Subsequently , the fourth stage (PS4) of the vehicle was moved to a higher circular orbit of 453 km after two restarts of the stage, to establish an orbital platform for carrying out experiments. Kalamsat-V2, a student payload, first to use PS4 as an orbital platform, was taken to its designated orbit about 1 hour and 40 minutes after lift-off. This flight marked the first mission of PSLV-DL, a new variant of PSLV with two strap-on motors. In the previous PSLV launch on November 29, PSLV-C43 had successfully launched India’s HysIS as well as 30 customer satellites from abroad.

ISRO has launched hyperspectral imaging satellite (HySIS), an earth observation satellite, from the Sriharikota. Over 30 foreign commercial satellites will be launched along with primary payload HySIS by the PSLV C43 rocket. The satellite, which can see in 55 spectral or colour bands from 630 km above the ground, will be used for a range of applications like agriculture, forestry and assessment of coastal zones, inland waters, soil and other geological environments. Being an earth observation satellite, HySIS will also be used by the military for surveillance purpose. The optical imaging detector array chip in the HySIS satellite has been designed by Isro's Ahmedabad-based Space Applications Centre and manufactured by its electronic arm, Semi-Conductor Laboratory, Chandigarh. The hyspex technology is still an evolving science and has become a new global trend. Hyperspectral imaging combines the power of digital imaging and spectroscopy. It collects and processes information from across the electromagnetic spectrum. Hyspex imaging enables distinct identification of objects, material or processes on the Earth by reading the spectrum for each pixel of a scene from space. Soon after the HySIS launch on November 29, Isro will shift its eye to the European spaceport as its heaviest commercial satellite Gsat-11 weighing 5.7 tonnes will be launched from French Guiana on December 5 (December 4 evening according to Indian standard time). The high-throughput satellite, which carries 40 transponders in the Ku-band and Ka-band frequencies, is capable of "providing high bandwidth connectivity" with up to 14 gigabit per second (GBPS) data transfer speed. Gsat-11, which will help increase internet speed in the country, was earlier this year recalled from French Guiana in order to check for possible glitches. Isro felt the need to take the unusual step of recalling the satellite in April as a precaution especially after the failure of the Gsat-6A satellite mission around the same time.

- Social media : These are interactive computer-mediated technologies that facilitate the creation and sharing of information, ideas, career interests and other forms of expression via virtual communities and networks US scientists have developed a web-based tool to help monitor the prevalence of fake news on social media platforms like Facebook and Twitter. Developed by researchers at the University of Michigan in the US, the tool uses a Platform Health Metric called the Iffy Quotient, which draws data from two external entities: NewsWhip and Media Bias/Fact Checker. NewsWhip, a social media engagement tracking firm, collects URLs on hundreds of thousands of sites every day and then gathers information on which of those sites have engagements on Facebook and Twitter. Iffy Quotient queries NewsWhip for the top 5,000 most popular URLs on the two social media platforms. Then the tool checks to see if those domain names have been flagged by Media Bias/Fact Check, an independent site that classifies various sources based on their reliability and bias. The first report issued by the researchers confirms what was suspected about the 2016 US presidential election: the Iffy Quotient increased dramatically on both Facebook and Twitter during the election.

Bread wheat, or common wheat, is the most common species. Several other closely related species include durum, spelt, emmer, einkorn, and Khorasan wheat. Scientists have decoded the entire DNA of wheat for the first time. Researchers hope the findings will allow them to produce new low allergy varieties as well as crops that need less water. It is hoped the research will benefit sufferers from Coeliac disease - who become ill when eating gluten. It is the world's most widely-cultivated crop on Earth and detailing it was a far more complex task than that of the human genome. Wheat has 16 billion base pairs - the building blocks of DNA - five times more than the humans. More than 200 scientists from 73 research institutions including the UK's John Innes Centre worked on the mammoth task - the results of which are published in the journal Science. Wheat has 21 chromosomes, 107,891 genes and more than 4 million molecular markers.
- Cyclone warning centre: It is one of the most important functions of the Indian Meteorological Department. The Centre has proposed to set up a Cyclone Warning Centre in Thiruvananthapuram. New centre would further strengthen the present forecasting activity in IMD's existing office in Kerala. The ministry is also planning to set up another C-Band Doppler Weather Radar at Mangalore by end of 2019 which would cover the northern parts of Kerala. At present, there are two Doppler Weather Radars in the state -- at Kochi and Thiruvananthapuram. With these three radars, the entire state would be covered for monitoring of rainfall and severe weather events, and adequately warn the people well in advance. The IMD has developed many new models and tools from nowcasts (2-3 hours) to extended range forecasts (15-20 days' lead time). The MoES is also planning to organise an awareness and training workshop for the state disaster management authorities of all states and other stakeholders by next month, to brief and train them on the new tools and their use for effective decision making.
- Global Positioning System (GPS): It is a satellite navigation system used to determine the ground position of an object. Researchers from the Massachusetts Institute of Technology (MIT) have developed an in-body GPS system, called ReMix, which can identify the location of ingestible implants inside the body via low-power wireless signals. Scientists team expects that such implants can be used to track tumours by monitoring even slight movements. In the future, the implants may also help in dispensing drugs to a specific area in the body. ReMix is being developed by MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) in alliance with Massachusetts General Hospital (MGH). The in-body GPS system is based on a wireless technology that MIT previously developed to detect heart rate, breathing and movement. To validate the system, the researchers implanted a small marker in animal tissues. They used a wireless device that reflects radio signals off the patient to track the marker's movement. This marker does not transmit any signals of its own. It merely reflects those transmitted by the wireless device. As a result, the marker does not need a battery or any external source of energy.
- Laboratory of Conservation of Endangered Species: It is a first of its kind genetic resource bank, which could have far reaching implications in conservation and revival of extinct and endangered species in the near future. It was inaugurated at Centre for Cellular and Molecular Biology's (CCMB) Laboratory of Conservation of Endangered Species (LaCONES) facility. It is dubbed as National Wildlife Genetic Resource Bank and inaugurated by Union Minister for Science and Technology and Environment, Forest and Climate Change, Dr. Harsh Vardhan, the genetic bank will cryopreserve living cell lines, gametes and embryos of endangered wild animal species in India.

The 21,000-tonne barge will be towed in the summer of 2019 to the port of Pevek in the autonomous Chukotka region in Russia's extreme northeast, 350 kilometres north of the Arctic Circle. The barge can produce enough electricity to power a town of 2,00,000 residents, far more than the 5,000 who live in Pevek, Russia's northernmost town. It will be primarily used to power oil rigs as Russia pushes further north into the Arctic to drill for oil and gas and needs electricity in far-flung locations.
- Nipah Virus: Nipah Virus is a newly emerging zoonosis that causes a severe disease in both animals and humans. This virus was first identified in Malaysia and Singapore in 1998. At that time, it was primarily caused in pigs and through them got transferred to humans. Nipah Virus infected as many as 265 people then, out of which 40 per cent were taken under intensive care due to the infection having spread severely. As quoted by the WHO, the natural host of the virus are fruit bats of the Pteropodidae Family, Pteropus genus. Nipah Virus is usually associated with inflammation of the brain due to which severe days of fever can often lead to a state of confusion, disorientation and even persistent drowsiness. If not taken care of, these symptoms can even cause a coma in a span of 24-48 hours. There are many patients who show neurological, respiratory and pulmonary signs as well. Therefore, do not ignore any such signs.
- New frog species: Scientists from Karnataka have found a new frog species in a small industrial region in coastal Karnataka. The new frog named as Microhyla kodial after the city of Mangaluru (called kodial in the Konkani language) from where they spotted it two years ago.

The accidental break through could help solve the global plastic pollution crisis by enabling for the first time the full recycling of bottles. The new bacterium was found eating plastic at a waste dump in Japan. Scientists have now revealed the detailed structure of the crucial enzyme produced by the bug. Prof John McGeehan, at the University of Portsmouth, UK, who led the research said, What we are hoping to do is use this enzyme to turn this plastic back into its original components, so we can literally recycle it back to plastic. It means we won't need to dig up any more oil and, fundamentally, it should reduce the amount of plastic in the environment.
- Odilorhabins: It is new class of antibiotics, discovered by a team of scientists from the University of Illinois, Chicago (US). Odilorhabdins are produced by a symbiotic bacterium found in soil-dwelling nematode worms. Called Xenorhabdus nematophila, the bacterial symbiont produces toxins and immuno-modulators, enabling the nematode to colonize and kill insects. The bacteria further benefit the host nematode by releasing antibiotics that prevent the invasion of the insect's carcass by other competing bacteria and fungi.

Efforts are underway to establish the link with the satellite. The second orbit raising operation of GSAT-6A satellite has been successfully carried out by LAM Engine firing for about 53 minutes on March 31, 2018, in the morning.
- TRAI: The Telecom Regulatory Authority of India (TRAI) is a statutory body set up by the Government of India under section 3 of the Telecom Regulatory Authority of India Act, 1997. It is the regulator of the telecommunications sector in India. The Telecom Regulatory Authority of India (TRAI) has mooted a concept of open architecture-based public Wi-Fi grid to bring down the cost of internet by 90 per cent. This will allow small entrepreneurs like tea stalls, grocery shops and vendors to set up and maintain access points. Device manufacturers, payment companies, ISPs/telcos and consumer internet companies can provide the remaining pieces to set up public data offices (PDOs). The regulator's concept involves PDOs much like PCOs of yesteryears that galvanised connectivity. The PDOs will be companies, or even small merchants, interested in providing Wi-Fi hotspots to public either free or on payment model. According to the report submitted to telecom ministry, the products available for consumption should begin from sachet sized, that is, low denomination, as low as ₹2. It said users should be able to easily discover the network, do one-click authentication and payment and connect their devices in Wi-Fi hotspots.
Eel is any of more than 800 species of teleost fishes characterized by elongate wormlike bodies. Researchers have discovered three new kinds of species of eel along the northern Bay of Bengal. Describing the species, Anil Mohapatra, the scientist at Zoological Survey of India (ZSI) said, Dark brown with white dots on the dorsal side known as Gymnothorax pseudotile was discovered at the Digha coast of the Bay of Bengal. The other two species, Gymnothorax visakhaensis (uniformly brown) and Enchelycore propinqua (reddish brown body mottled with irregular creamy white spots), were discovered from the Visakhapatnam coast of the Bay of Bengal. While Gymnothorax pseudotile is about 1 feet to 1.5 feet long, Gymnothorax visakhaensis is about a foot long. Enchelycore propinqua is the smallest of them measuring less than a foot. A description of all the three new species was published in the journal Zootaxa.
World's smallest satellite - Japan successfully launched on the world's smallest satellite-carrying rocket following a failed attempt in January last year. According to a release from the Japan Aerospace Exploration Agency, 'The rocket about the size of a utility pole, measuring 10 meters in length and 50 centimeters in diameter, lifted off from the Uchinoura Space Center in Kagoshima Prefecture and delivered its payload to its intended orbit'. The No. 5 vehicle of the SS-520 series carried a microsatellite weighing about 3 kilograms developed by the University of Tokyo to collect imagery of the Earth's surface. The launch was aimed at verifying JAXA's technology used to launch small rockets made with commercially available components at lower cost amid growing global demand for microsatellites. The agency used components found in home electronics and smartphones for the rocket. JAXA launched the No. 4 vehicle on Jan. 15 last year, but terminated its flight shortly after liftoff due to a communications problem. The agency found that vibrations during liftoff caused a short circuit, leading to a loss of power in the data transmitter. For Saturday's launch, the agency made more than 40 improvements to prevent a recurrence.

- Scientists developed Device to detect Gastro-Intestinal Cancers
Scientists developed a prototype of an advanced multi-bending cholangioscope to detect and cure Gastro-Intestinal Cancers. Earlier, most patients used to visit a physician when the disease was in an advanced stage. This new equipment has a video camera and can bend easily. It could detect cancers of bile duct, liver and pancreas. It will help in detecting the disease in early stage.
The multi-bending peroral direct cholangioscope (PDCS) cannot be inserted free-hand into the bile duct. But a high success rate of direct insertion will be achieved if the endoscope is passed over a guide-wire and an anchoring balloon. In fact, pancreatic cancer is the third most prevalent gastro-intestinal cancer in India whereas liver cancer is the most common.
- Union Government Approved Project for National Optical Fibre Network Creation in Gram Panchayats

Our Milky Way in Midst of life crisis
Indian communication satellite GSAT-8 successfully launched
- Planetary scientist say that our Milky way is in its mid life crisis as a result of which it will slow down its process of production of stars in the next billion years. As per the aeronautics the galaxies are classified under two categories namely- energetic blue galaxies and the lethargic red galaxies. The blue galaxies produce stars at a massive rate while the other one are slowly dying. But a team of scientist from the Swinburne University of Technology says that our Milky Way falls into neither of the two categories. It is in fact a green valley galaxy that lays half way between the blue galaxy and the red galaxy.
- This is the first time ever that scientists have compared both the galaxies with our Milky Way as the Astrophysical Journal reported. Though we are in our own galaxy and to determine its state was a tough job to accomplish was reported by the Astrophysical Journal.
- India’s communication satellite GSAT-8 was launched successfully. The satellite was launched by Arianespace from Kourou in French Guiana. The satellite was launched to enable powerful services direct to our home. The satellite weighs 3100kg and is one the heaviest and high powered satellite developed by the Indian Scientist at the Bangalore- headquarters ISRO. The ISRO team that launched the satellite showed extreme pleasure at the successful launch of the satellite.
- "I am extremely delighted and happy to announce that ISRO successfully launched the satellite and we are happy to confirm that we have taken the charge of the satellite immediately after its injection into the orbit” ISRO Chairman K Radhakrishnan said.
