Current Affairs in Science and Technology - July 2020

DST: It refers to the Department of Science & Technology. DST is a department within the Ministry of Science and Technology in India. It was founded on 3 May 1971. It's responsibility is to promote new areas of science and technology and to play the role of a nodal department for organizing, coordinating and promoting Scientific and Technological activities in the country. It gives funds to various approved scientific projects in India. It also supports various researchers in India to attend conferences abroad and to go for experimental works. Minister of State Dr. Harsh Vardhan is the current head of the department, while Ashutosh Sharma is its present secretary. The DST now operates Open Access Policy.

Recently, the Secretary Prof Ashutosh Sharma of DST launched the official Logo to celebrate Golden Jubilee Commemoration Year of DST.

The newly launched logo will be printed on stationery items of DST, social, digital, and print documents. DST has been directed to use AI to the newly launched 50 Year logo by representing it on banners in conferences held in the institutes.

DST is observing Golden Jubilee Commemoration Year between the period 3rd May 2020 to 2nd May 2021 with activities like lecture series, bringing out publications, documentaries, updating Wikipedia pages of Survey of India, and Autonomous Institutions under DST etc.

Drones: A drone is an unmanned aerial vehicle (UAV) or uncrewed aerial vehicle. It is an aircraft without a human pilot on board and a type of unmanned vehicle. Essentially, a drone is a flying robot that can be remotely controlled or fly autonomously through software-controlled flight plans in their embedded systems, working in conjunction with onboard sensors and GPS. Abraham Karem who was born in Baghdad to a Jewish couple is regarded as the founding father of UAV (drone) technology. During WWII, Reginald Denny created the first remote-controlled aircraft called the Radioplane OQ-2. This was the first massed produced UAV product in the U.S and was a breakthrough in manufacturing and supply drones for the military.

Recently, India has become the first country to control locusts through drones after finalizing the protocols and getting all statutory approvals. Locust control operations are going on in Rajasthan, Madhya Pradesh, Punjab, Uttar Pradesh, Haryana, Gujarat and Maharashtra. In total 60 ground control teams of Locust Circle Offices and 12 drones are being used for the operations

Under the Make in India initiative, the Department of Agriculture, Cooperation & Farmers’ Welfare (DAC&FW), Agriculture Ministry has indigenously developed a vehicle-mounted Ultra-low volume (ULV) sprayer for locust control. Locust is a crop-threatening migratory pest that has entered the country through the India-Pakistan border.

Aerial spray by drones was used for locust control because the ground control vehicles sprayers have the ability to spray up to a height of 25-30 feet only. The tractor-mounted sprayers too have a limitation in reaching inaccessible areas and tall trees.

Project Platina: Project Platina is the World’s largest Convalescent Plasma Therapy Trial project. Project Platina was recently launched by the Chief Minister of Maharashtra Uddhav Thackeray. It was launched virtually at Nagpur’s government medical college.

The Indian Council of Medical Research (ICMR) has given the approval to conduct convalescent plasma therapy trials at 23 centres but as of now it will be done at 17 centres and 4 medical colleges of BMC in Mumbai. 

The project will help Maharashtra as it has been the worst-hit state in India to create a robust data for the use of Convalescent Plasma Therapy and also  help in establishing an infrastructure for plasma treatment in the state.

Convalescent plasma therapy (CPT): Plasma therapy or Convalescent Plasma Therapy (CPT) has been proved to be useful in fighting other coronavirus diseases, such as SARS and MERS. It aims to make use of the antibodies developed in the recovered patient against the infections.

Under this therapy, the whole blood or plasma will be obtained from those patients who have recevered from COVID-19 and then the blood is injected into critically ill patients so that the antibodies are transferred and boost their fight against the virus.

PULSE: It is a 3D printed device invented by NASA. This  new innovation has been named, 'PULSE'. The app works by alerting the wearer of the gadget to stop exposure to the risky activity. When a person, wearing the gadget gets their hand too close to the face (knowingly or unknowingly), PULSE triggers a beeping noise and alerts the wearer of the same.

The gadget is shaped like a pendant and it is to be worn around the neck. It works best when placed 6 inches below the chin. It has a tiny vibration motor in place. The haptic feedback from a vibration motor simulates a nudge, reminding the wearer to avoid touching these entryways in order to reduce potential infection", reads a statement released by the makers.

NASA: It is an acronym for National Aeronautics and Space Administration. NASA is an independent agency of the United States Federal Government responsible for the civilian space program, as well as aeronautics and aerospace research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA). It is headquartered in Washington, D.C., United States. The Administrator of NASA is Jim Bridenstine and the Deputy Administrator of NASA is James Morhard.

MeitY: It refers to the Ministry of Electronics and Information Technology. MeitY is an executive agency of the Union Government of the Republic of India. It was carved out of the Ministry of Communications and Information Technology on 19 July 2016 as a standalone ministerial agency responsible for IT policy, strategy and development of the electronics industry. The current Union Minister of Electronics & Information Technology is Ravi Shankar Prasad.

Recently, the Ministry of Electronics and Information Technology (MeitY) in partnership with Atal Innovation Mission – NITI Aayog launched a Digital India Aatmanirbhar Bharat App Innovation Challenge for Indian tech entrepreneurs and startups. The challenge will aim to help realise the vision of Prime Minister for building a Digital India.

This innovative challenge which will be open for tech entrepreneurs and startups will have two tracks. Track one will be the promotion of existing apps and track two will be the development of new apps.

Track 1: In the first part of the App Innovation Challenge has cash awards and incentives for apps. It is aimed at creating an ecosystem where Indian entrepreneurs and startups are inspired to ideate, incubate, build, nurture and sustain tech solutions that can serve not only the country, but also the world - “Make in India for India and the World”.

Under the challenge, innovators are invited to develop apps in 8 categories. They are Office Productivity & Work from Home, E-learning, Social Networking, Health & Wellness, News, Entertainment, Games and Business including Agritech and Fin-tech. The Innovation Challenge has been made available on innovating .mygov.in/app-challenge from 4th July 2020. Track-1 is likely to be completed in a month.

Track 2: Track 2 which is yet to be launched will begin when Track 1 is completed.  It aims to seek to identify Indian startups,entrepreneurs,companies and encourage them with ideation, incubation, prototyping, and roll out of applications. This track will run for a longer duration of time. The details about the exact duration of this phase will be issued soon by the Ministry.


Current Affairs in Science and Technology - June 2020

ANITA: It refers to Antarctic Impulsive Transient Antenna. ANITA is the first NASA observatory for neutrinos of any kind. It is a radio telescope to detect ultra-high energy cosmic-ray neutrinos from a scientific balloon flying over the continent of Antarctica. ANITA detects neutrinos pinging in from space and colliding with matter in the Antarctic ice sheet through the Askaryan effect.

Recently, NASA’s Antarctic Impulsive Transient Antenna(ANITA) have detected high energy particles from ice in Antarctica. The researchers believe that these particles are proof to parallel universe.

The high-energy particles usually move from space to earth (i.e. from top to bottom) but ANITA has detected an anomaly i.e. particles have been detected travelling bottom to top.

The ANTIA has so far made 4 major cosmic ray detections. The cosmic rays that are coming from the sky are reflected off the ice. However, two of these detections have proofs that they are generated from the ice below.

Askaryan effect: It is the phenomenon where a particle travelling at a velocity faster than light in a dense electric medium, produces shower of secondary charged particles. The dense electric medium can be ice, salt of lunar regolith. It is named after Gurgen Askaryan, a Soviet-Armenian physicist who postulated it in 1962.

Neutrinos: They are subatomic particles with no electric charge and with a very small mass. The mass of the neutrino is much smaller than that of the other known elementary particles.They are considered to be the second most abundant particle in the universe after photons or light particles.The direction from which they arrive points directly back to their original source. They are produced during natural radioactive decays and all sorts of nuclear reactions in nuclear power reactors, particle accelerators or nuclear bombs.

However, the most common sources of neutrinos are celestial phenomena which is natural nuclear reactions like the birth and death of stars, collisions, and explosions happening in space.

NASA: It is an acronym for National Aeronautics and Space Administration. NASA is an independent agency of the United States Federal Government responsible for the civilian space program, as well as aeronautics and aerospace research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA). It is headquartered in Washington, D.C., United States. The Administrator of NASA is Jim Bridenstine and the Deputy Administrator of NASA is James Morhard. 

Recently, NASA renamed its next-generation space telescope- Wide-Field Infrared Survey Telescope (WFIRST), after the space agency’s first chief astronomer Nancy Grace Roman. The WFIRST Telescope will now be called Nancy Grace Roman Space Telescope (or Roman Space Telescope, for short) which is set for launch in 2025.

Nancy Grace Roman: She is the US space agency’s first chief astronomer. She came to NASA in 1959, just 6 months after the agency had been established. She paved the way for space telescopes focused on the broader universe. She is considered as the mother of Hubble Space Telescope, which had launched 30 years ago. Through Roman's leadership, NASA launched four Orbiting Astronomical Observatories between 1966 and 1972.

TIANWEN-1: It is China's first Mars mission. China’s space program is planning to launch its first Mars mission named ‘Tianwen-1’ which is expected to land on the Red Planet’s surface in the first quarter of 2021.

 The Tianwen-1 mission will lift off on a Long March 5 rocket. It is expected to take off in late July, around the same time when NASA is launching its own Mars mission– the ambitious ‘Perseverance’ which aims to collect Martian samples and bring them back to Earth in a two-part campaign.

The success of the mission will make China the third country to achieve a Mars landing after the USSR and the United States.

Previous Mars missions:

China’s previous ‘Yinghuo-1’ Mars mission, which had piggybacked on a Russian spacecraft, had failed after it could not leave the Earth’s orbit and disintegrated over the Pacific Ocean in 2012.

The USSR in 1971 became the first country to carry out a Mars landing. It’s Mars 3 lander is able to transmit data for 20 seconds from the Martian surface before failing. The country made it’s second and Mars landing two years later in 1973.

The US holds the maximum records on Mars landings missions, the latest mission being the  ‘InSight’ in 2019 (launched in 2018).

The Mars Orbiter Mission (MOM), also called Mangalyaan is a space probe orbiting Mars since 24 September 2014. It was launched on 5 November 2013 by the Indian Space Research Organisation (ISRO).

Trojan Asteroid: These are Jupiter trojans, commonly called Trojan asteroids or simply Trojans . They are a large group of asteroids that share the planet Jupiter's orbit around the Sun. Relative to Jupiter, each Trojan librates around one of Jupiter's two stable Lagrange points: L4, lying 60° ahead of the planet in its orbit, and L5, 60° behind.

Recently, astronomers at the University of Hawaii's Institute for Astronomy (UH IfA) have spotted a new asteroid with a comet-like tail moving in the same orbit as Jupiter. It is described as something between an asteroid and a comet. The object has been called an active asteroid.

They are usually known as Trojan asteroids. However, it is the first one of its kind to be seen with a comet-like-tail. The object has been called an active asteroid because these objects appear to be asteroids at first, but later develop activity, such as tails, like that of comets.

The object was first discovered in June 2019 and given the name 2019 LD2. It was discovered using the university's Asteroid Terrestrial-impact Last Alert System (ATLAS), which was funded by NASA and developed to search space for objects that may pose threats to the Earth. It was discovered moving in the same orbit travelled by Jupiter around the sun. These asteroids follow the same orbit like that of a planet. But it remains 60 degrees ahead of or behind along the orbit.

The Jupiter Trojan asteroids orbit the Sun in two huge swarms, one swarm orbiting ahead of the planet (where 2019 LD2 was found) and one swarm orbiting behind it.

As per the researchers, the Trojan asteroids have been captured into these orbits by Jupiter's strong gravity. 2019 LD2 is the first-of-its-kind as because most Jupiter Trojans were captured billions of years ago.

Ultra Swachh: It is a disinfection unit named Ultra Swachh to disinfect a wide range of materials, including Personal Protective Equipment (PPEs), electronics items, fabrics, etc. It has been developed by Defence Research and Development Organisation (DRDO).

DRDO's Delhi based Institute of Nuclear Medicine & Allied Sciences (INMAS) developed this product with industry partner M/s Gel Craft Healthcare Private Ltd, Ghaziabad in compliance with International Standards of Industrial, Occupational, Personal and Environmental Safety.

The Ultra Swachh comes in two variants namely Ozonated Space and Trinetra Technology. Trinetra technology is the combination of Ozonated space and radical dispenser. Treatment is optimised with automation for quick disinfection cycle. The system uses an advanced oxidative process comprising of Ozonated Space Technology and uses the advanced oxidative process for disinfection process.

The system is double layered with specialised Ozone sealant technology assuring trapping of ozone for the necessary disinfection cycle. It also has catalytic converter to ensure environment friendly exhaust i.e. only oxygen and water.

SpaceX: Space Exploration Technologies Corp., trading as SpaceX, is an American aerospace manufacturer and space transportation services company. It was founded on 6 May 2002 by Elon Musk with the goal of reducing space transportation costs to enable the colonization of Mars. It is headquartered in Hawthorne, California. The SpaceX founder & CEO is Elon Musk. The current SpaceX president & COO is Gwynne Shotwell.

Recently, marking the beginning of a new era in the United States (US) space programme, NASA astronauts Robrt Behnken and Douglas Hurley docked the SpaceX capsule with the International Space Station (ISS). The two NASA astronauts made history on Saturday as they became the first Americans to launch on a US rocket from American soil to the space station in nearly a decade. 

The SpaceX’s Falcon 9 with Crew Dragon capsule – Endeavour  designed and built by Elon Musk’s SpaceX lifted off on May 30 at 3:22 p.m (1.50 am Sunday in India) from Pad 39A at NASA’s Kennedy Space Center at Cape Canaveral, Florida. It is the same launch pad, which was used during the Apollo mission to the moon a half-century ago. With this, SpaceX has become the first private company to fly astronauts into orbit.

Coro-bot: It is an ‘Internet-controlled’ robot developed by a 23 year old engineer Pratik Tirodkar from Thane. Coro-bot which is designed and created by him is the first of its kind that addresses the needs of the hospitals treating COVID-19 patients.

This robot can be operated from any part of the world through internet. It can deliver food, water, medicines and interact with the patients through a camera. Through a speaker, it can also advise patients on various precautions like sanitizing their hands before picking up anything from the robotic tray. It eliminates the need of physical presence or contact of nurses or ward boys with the patient.

The Coro-bot has three nozzles. The first nozzle is used to provide disinfectant bath for the robot himself, the second is used to spray sanitizers on both sides of the path and the third is used to disinfect the ground with UV light as the robot moves. It also has dispensers for water, tea and coffee.

The robot becomes the first in world to be operated using Internet of Things (IoT) technology in medical field.

Pratik Tirodkar: He is designer and creator of the first of its kind robot named Coro-bot. He is also the founder of a start up ‘PNT solutions’. He has developed other unique creations when he had barely stepped to college. This includes world’s first ‘Humanoid’ with 47 body (axis) movements, a robotic bird ornithopter for various outdoor applications, a mini packaging robot and several others.

This young genius has even given over a 100 guest lecturers to the brain students of IITs and NITs in the country.

3. Electric ferry boats (passenger boats)

Recently, India’s first solar-powered ferry, Aditya has been shortlisted for the Gustave Trouvé Award as the sole entrant from Asia. It has been shortlisted for  Electric ferry boats (passenger boats) category award.

Aditya:  Aditya is a solar-powered ferry operating between Vaikkom and Thavanakkadavu in the Indian state of Kerala. It is not only the first solar-powered ferryand but also the largest solar-powered boat in India. The boat was inaugurated by Kerala Chief Minister Sri. Pinarayi Vijayan and Central Cabinet Minister for Power, Renewable Energy, Sri. Piyush Goyal on 12 January 2017. The vessel was designed and built by NavAlt Solar and Electric Boats in Kochi, India. It is operated by the Kerala State Water Transport Department (KSWTD).

It is powered by a motor that can source energy from solar panels, batteries, and generators so the per km energy cost of Aditya is low and it does not create air and noise pollution. It operates 22 trips a day, covering a total of 66 km, carrying 75 passengers per trip. It covers a total distance of 66 km with just ₹180 per day energy cost. Till now the ferry has transported 11 lakh passengers, covering a distance of 70,000 with a zero carbon footprint.

Health Ministry: The Ministry of Health and Family Welfare is an Indian government ministry charged with health policy in India. It is also responsible for all government programs relating to family planning in India. The Minister of Health and Family Welfare holds cabinet rank as a member of the Council of Ministers. It was founded in 1976.The current Minister of Health and Family welfare is Harsh Vardhan.

Recently, Union Minister of Health and Family Welfare Dr Harsh Vardhan launched India's first mobile I-Lab (Infectious disease diagnostic lab). It is part of government Aatmnirbhar Bharat. It was built in a record time of 8 days from the date of receipt of Automotive Chassis, from Bharat Benz. The laboratory aims to promote and support the idea of becoming self sufficient in difficult times.

The Laboratory is to be deployed in remote, interior and inaccessible parts of the country. It has the capability to perform 25 Covid-19 RT-PCR tests per day, 300 ELISA tests per day and additional tests for TB and HIV.

Antarctica: Antarctica is the southernmost continent and site of the South Pole. it is a virtually uninhabited, ice-covered landmass. It is surrounded by the Southern Ocean. Most cruises to the continent visit the Antarctic Peninsula, which stretches toward South America. It’s known for the Lemaire Channel and Paradise Harbor, striking, iceberg-flanked passageways, and Port Lockroy, a former British research station turned museum. The peninsula’s isolated terrain also shelters rich wildlife, including many penguins. Antarctica is bigger than Europe and almost double the size of Australia. Most of Antarctica is covered in ice over 1.6 kilometres thick (1 mile). It is the coldest continent on Earth with the lowest recorded temperature reaching -89.2 degrees Celsius. Not only is Antarctica the coldest continent, it is also the driest, highest and windiest with winds reaching over 200mp.

Recently, in a new study published in the journal Nature has revealed that a mysterious fossil discovered in Antarctica in 2011 turned out to be a giant soft-shell egg from 68 million years ago.  It Measures upto 29 cm by 20 cm and it is the first fossil egg found in Antarctica and the largest soft-shell egg that the world has ever seen. 

A group of Chilean researchers from South American Nation Chile, during a scientific expeditiond, discovered a fossil 200 meters away from the spot where the fossil of a 10-meter long Mosasaur (an ancient reptile) was unearthed. This egg shaped fossil was discovered on the Seymour Island of Antarctica off the coast of Antarctica. The fossil, since then was kept in the Chilean National Museum of Natural History and was named ‘The Thing’ for almost a decade before being studied. Though, there was nothing left inside the egg to prove what animal it once carried but some scientists speculate that it was laid by a giant marine reptile.

Fossils: Fossils are the preserved remains, or traces of remains, of ancient organisms. Fossils are not the remains of the organism itself! They are rocks. It can be any preserved remains, impression, or trace of any once-living thing from a past geological age. For e.g., bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, Bones, shells, feathers, leaves and DNA remnants. A fossil can preserve an entire organism or just be a part of one.

LUS: It refers to an automated lung ultrasound (LUS) for COVID-19 screening and monitoring through cloud-based image analysis and scoring system. It has recently been developed by Indian Institutes of Technology (IIT), Palakkad.

The app is the first of its kind in India. It is now available for clinicians to perform automated analysis by just uploading the ultrasound video.

A nursing assistant (in the absence of a skilled clinician) by following a simple protocol of LUS, acquires the lung images and transfers the images to the cloud.

The images are analyzed over the cloud and scores are assigned according to certain criteria either for the type of infection or its severity.

The methodology would be extremely useful in time-critical COVID-19 working conditions, where clinicians have time limitations in manually evaluating ultrasound videos of all patients.

The approach is not only restricted to COVID-19 detection but also helps to identify other lung infections.

LUS has the additional advantage because it is easy to use, portable, repeatability, absence of radiation exposure, and it is of low cost.

BDS: It refers to the BeiDou Navigation Satellite System. The BDS is named after the Chinese term for Big Dipper. It is a Chinese satellite navigation system. The BDS has been designed to reach accuracy levels similar to those of GPS and Galileo Open Service by positioning accuracy within 10 meters, timing accuracy within 50 ns and velocity accuracy within 0.2 meters per second. China started developing the Beidou satellite system in the 1990s with the aim of being self-sufficient in navigation technology and having an alternative system to GPS.

Recently, China successfully launched the final member in its Beidou satellite system (BDS) for global coverage constellation. It was launched from the Xichang Satellite Launch center in Sichuan Province on 23 June 2020 by a Long March 3B rocket into the orbit. The satellite launched is a part of the third generation of the BeiDou Navigation Satellite System (BDS-3) and the 55th satellite of the whole Beidou system.

The launch marked the completion of the country's domestically developed BeiDou constellation, one of four global navigation networks alongside with the United States Global Positioning System GPS, Russia's GLONASS and the European Union's Galileo. BDS is being projected by Beijing as a rival to the American Global Positioning System (GPS).

BDS-1 also known as the first generation was a constellation of 3 satellites was launched with 3 working and one backup satellite between 2000 to 2003. The first satellite under this system was launched on 30th October 2000. The BDS started providing independent services over China in 2000.

BeiDou-2 also known as the second generation of the system became operational in China in 2011 with a partial constellation of 10 satellites in orbit. This system provides coverage in the Asia-Pacific Region. The first satellite under this system was launched on 13th April 2007.

BDS-3 also known as the third generation of the system was launched on 30 March 2015. The BDS-3 System satellite has a higher bandwidth, enabling enhanced communication. This system consists of 35 satellites. They are 3 Geosynchronous satellite, 3 Inclined Geosynchronous Satellite and 24 Medium Earth Orbits Satellite. Fifteen BDS-3 satellites were launched till October 2018. BDS-3 started providing global navigation services from December 2018 to countries that had signed the Belt and Road Initiative (BRI) of China.

ISRO: It is an abbreviation for the Indian Space Research Organizatin.  ISRO is the space agency of the Government of India (GoI) and was formed in 15 august 1969. It superseded the erstwhile “Indian National Committee For Space Research” (INCOSPAR) which was established in 1962 by the efforts of Independent India's first prime minister‚ Jawaharlal Nehru‚ and his close aide and scientist Vikram Sarabhai. In 1972, the Government of India had set up a Space Commission and the Department of Space (DOS), bringing ISRO under the DOS. ISRO then embarked on its mission to provide the Nation space based services and to develop the technologies to achieve the same independently. Its vision is to “harness space technology for natural development while pursuing space science research & planetary exploration”. ISRO built India’s first Satellite Aryabhata. It is headquartered in Bangalore, India. The current Chairman of ISRO is K sivan.

Recently, ISRO received a patent for its Liquid Cooling and Heating Garment (LCHG) that is suitable for space applications.

LCHG are made of biocompatible fabrics and components to provide a comfortable temperature and removal of sweat for astronauts, for use in space for protection from hot and cold environments. The patent garment has an outer layer that is made of polymeric fabric net and the inner layer of polymeric fabric tricoting that comes in contact with the wearer. The outer and inner layers are separated by tubes configured to circulate heat transfer through inlet and outlet valves. The garment permits the long term use without any impact on the wearer in terms of skin irritation or infection.

LCGH was invented by Srirangam Siripothu, Reshmi Balachandran, Saraswathi Kesava Pillai Manu, and Gurumurthy Chandrasekaran.

LCGH would provide a comfortable temperature to the astronauts wearing it in space. It can also be used in  military applications, fire fighting as well as for personal cooling and heating purposes for protection from extreme hot and cold environments of industrial areas.

ISRO has initiated the Human Space Flight Programme, Gaganyaan, to take humans to space by 2022. Under the programme, three astronauts are to orbit the earth at an altitude of 400 kilometres for 7 days. They are undergoing training in Russia.

Space Sector Reforms: The Union Cabinet recently has approved far reaching reforms in the Space sector. It was approved in the Cabinet meeting held under the chairmanship of Prime Minister Narendra Modi with an aim to boostprivate sector participation in the entire range of space activities.

The Cabinet decision comes weeks after Finance Minister Nirmala Sitharaman announced the opening up of the space sector for private entities.

Union Atomic Energy and Space Minister, Dr. Jitendra Singh informed that that government will constitute Indian National Space Promotion and Authorization Centre (IN-SPACE) for effective socio-economic usage of space technology.

The Public Sector Enterprise, New Space India Limited (NSIL) will endeavour to re-orient space activities from a supply driven model to a demand driven model, thereby ensuring optimum utilization of our space assets.

IN-SPACe will not only provide a level playing field for private companies to use Indian space infrastructure but will also guide them through encouraging policies and a friendly regulatory environment.

IN-SPACe will not be a separate institution but work as an extension into ISRO and these reforms will allow ISRO to focus more on research and development activities, new technologies, exploration missions and human spaceflight programme. The Department of Space comes under the PMO.

IISc Bangalore: It is the Indian Institute of Science located in Bangaluru city, in the Indian state of Karnataka. It is a public, deemed, research university for higher education and research in science, engineering, design, and management. The institute was established in 1909 with active support from Jamsetji Tata and Krishna Raja Wadiyar IV and thus is also locally known as the "Tata Institute". It was granted the deemed to be university status in 1958 and the Institute of Eminence status in 2018.

Recently, a research team at IISc Bangaluru developed nanozymes that destroy the cell membrane of bacteria by directly targeting its phospholipids. According to the former PhD students Kapudeep Karmakar and Kritika Khulbe, who conducted the research, the nanozymes developed by them can replace the antibiotics that have become ineffective as several bacteria have developed resistance to them by producing their own enzymes.

The study conducted by the Department of Inorganic and Physical Chemistry and the Department of Microbiology and Cell Biology was published in ACS Applied BioMaterials journal.

Nanozymes are nanomaterials that can behave like human enzymes. It can disintegrate the cell membranes of a range of diseases causing bacteria. This nanomaterial has been tested on several potentially pathogenic bacteria causing typhoid, gastroenteritis, dysentery, cholera and pneumonia. It was found that the nanozyme stopped growth and killed the microbes.

It also aims to create the first human settlement on red planet by 2117.
  • SoI:The Survey of India (SoI), which is country’s oldest department of central engineering agency for mapping and surveying the entire country, for the first time will deploy 300 drones for repairing unprecedented high resolution map of the country. It is affiliated to the Department of Science and Technology (DST). The aim is to map 75% of India’s geography— about 2.4 million sq km of the 3.2 million sq. km — within the next two years. Other than unprecedented detail, High-resolution maps will facilitate digitisation of land titles in villages. Currently the best SoI maps have a resolution of 1:250000, meaning a 1 cm on the map represent 2500 cm on the ground. The new maps being prepared will be of 1:500 resolution, meaning 1 cm will represent 500 cm. The drone mapping will not only help the SoI in getting unprecedented detail of country’s landscape but will also help in creating high resolution maps of land in villages facilitating digitisation of land titles there.
  • NCCCR&D:Water has been found by scientists in the atmosphere of an exoplanet called K2-18b. The exoplanet is twice the size and eight times the mass of Earth and hence, known as a super-Earth. Super-Earths are exoplanets that are larger than Earth but smaller than Neptune. The exoplanet orbits a red dwarf star, K2-18 and is 110 light-years away from Earth in the Leo constellation. It is the first planet outside the solar system in the habitable zone of its star.The K2-18b exoplanet completes one orbit around its star every 33 days.The super-Earth is much closer to its star than the Earth is to the sun. However, the red dwarf star is much cooler than the Sun. The discovery was published in a paper in a scientific journal, Nature Astronomy on September 11, 2019 by researchers from University College London (UCL). The paper revealed that scientists studied the atmosphere of K2-18b, a distant super-Earth and for the first time discovered water vapor in its atmosphere and temperature that could potentially support life. Though scientists have tagged exoplanet K2-18b as potentially habitable, it doesn’t mean that humans could live there. The research team used archived data collected by the Hubble Space Telescope between 2016 and 2017 that had captured starlight as it passed through the exoplanet’s atmosphere. When the researchers put the data through algorithms, they saw signs of water vapour in the atmosphere. The researchers also saw traces of hydrogen and helium in the atmosphere, two of the most abundant elements in the universe. The planet was first discovered by NASA's Kepler spacecraft in 2015.
  • Gaganyaan Mission :ISRO aims to launch its maiden Human Space Mission, Gaganyaan before the 75th anniversary of India’s independence in 2022. The Human Spaceflight Programme aims to carry three people to space to orbit the Earth for roughly about 7 days and bring them safely back to the ground. The crewed space mission is planned to be launched aboard ISRO’s GSLV Mk III in December 2021. So The Indian Space Research Organisation (ISRO) and Defence Research and Development Organisation (DRDO) signed a Memorandum of Agreement (MoU) for development of human-centric systems for the Human Space Mission to demonstrate its human space flight capabilities. The MoU was signed by a delegation of ISRO scientists, led by Human Space Flight Centre's Director, S Unnikrishnan Nair, with various DRDO labs in this regard, to provide technologies for human-centric systems and technologies specific to the Human Space Mission.

Farmers can download this mobile app on any android phone from Google Play Store. Farmers can get affordable access to cutting-edge technology at their doorsteps with the help of this mobile app. The issue of crop residue burning has become a major environmental problem causing health issues as well as contributing to global warming. There are some sustainable techniques like Composting, biochar production and mechanization that can help to curtail the issue while retaining the nutrients present in the crop residue in the soil. However, some steps by the government of India have taken to curtail this problem. Several measures and campaigns designed to promote sustainable management methods such as converting crop residue into energy have also started. In recent years, the alarming rise of air pollution levels caused by crop residue burning in the city of Delhi and other northern areas in India observed.

Twenty-five vans are being added in September 2019, which is also part of 100-day achievement of this government.
  • Samudrayaan Project:India, after Chandrayaan project is planning to explore the deep sea region with the 'Samudrayaan' project to undertake deep ocean mining .The 'Samudrayaan' is a pilot project of the Ministry of Earth Sciences for deep ocean mining for rare minerals. The 'Samudrayaan' project proposes to send men into the deep sea in a submersible vehicle for ocean studies. The project is expected to become a reality by 2021-22. The project has been undertaken by the National Institute of Ocean Technology (NIOT). NIOT Director MA Atmanand said that NIOT has similarly undertaken Samudrayaan as ISRO has envisioned carrying an astronaut to space under its 2022 'Gaganyaan' mission. Under the proposed 'Samudrayaan' project, three men will be sent into deep sea in a submersible vehicle to a depth of about 6000 metres to carry out various deep underwater studies. The submersible vehicle, which will be indigenously developed, would be capable of crawling on the sea bed at a depth of six-kilometer for 72 hours.The project will go deeper in phases with more trials and the ocean mining is expected to commence in 2022.The submarines deployed currently go only about 200 metres deep into the sea. The expenditure of the ambitious project is expected to be around Rs 200 crore. The significance of Samudrayaan project that if it id successful then India will join the league of developed nations in the exploration of minerals from oceans Developed countries have already carried out such missions. India could be the first developing country to undertake such a project. The 'Samudrayaan' will be a part of the Rs 6000 crore 'Deep Ocean’ mission that though has received in-principle approval but it is still awaiting final approval from the Union Finance Ministry. The final approvals are expected to come through in October 2019.
  • Chandrayaan-2: Chandrayaan-2 is an Indian lunar mission to explore the unchartered south pole of the celestial body by landing a rover. It is developed by the Indian Space Research Organisation (ISRO),after Chandrayaan-1.It consists of a lunar orbiter, the Vikram lander, and the Pragyan lunar rover, all of which were developed in India.The main scientific objective is to map the location and abundance of lunar water via Pragyan, and ongoing analysis from the orbiter circling at a lunar polar orbit of 100 × 100 km. The mission was launched to the Moon from the second launch pad at Satish Dhawan Space Centre on 22 July 2019 at 2.43 PM IST (09:13 UTC) by a Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III). The craft reached the Moon's orbit on 20 August 2019 and began orbital positioning manoeuvres for the landing of the Vikram lander. Vikram and the rover were scheduled to land on the near side of the Moon, in the south polar region at a latitude of about 70° south at approximately 1:50 am on 7 September 2019 and conduct scientific experiments for one lunar day, lasting two Earth weeks. However, at about 1:52 am IST, the lander deviated from its intended trajectory at around 2.1 kilometres (1.3 mi) from landing, and lost communication. Initial reports suggesting a crash have been confirmed by ISRO chairman K. Sivan, stating that the lander location had been found, and "it must had been a hard landing". The orbiter, part of the mission with eight scientific instruments, remains operational and will continue its seven-year mission to study the Moon. The Moon is the closest cosmic body at which space discovery can be attempted and documented. It is also a promising test bed to demonstrate technologies required for deep-space missions. Chandrayaan 2 attempts to foster a new age of discovery, increase our understanding of space, stimulate the advancement of technology, promote global alliances, and inspire a future generation of explorers and scientists. Moon provides the best linkage to Earth’s early history. It offers an undisturbed historical record of the inner Solar system environment. Though there are a few mature models, the origin of Moon still needs further explanations. Extensive mapping of lunar surface to study variations in lunar surface composition is essential to trace back the origin and evolution of the Moon. Evidence for water molecules discovered by Chandrayaan-1, requires further studies on the extent of water molecule distribution on the surface, below the surface and in the tenuous lunar exosphere to address the origin of water on Moon. The lunar South Pole is especially interesting because of the lunar surface area here that remains in shadow is much larger than that at the North Pole. There is a possibility of the presence of water in permanently shadowed areas around it. In addition, South Pole region has craters that are cold traps and contain a fossil record of the early Solar System.

  • Generic medicines:They are unbranded medicines which are equally safe and having the same efficacy as that of branded medicines in terms of their therapeutic value. The prices of generic medicines are much cheaper than their branded equivalent. Since the manufacture of these generic drugs do not involve a repeat of the extensive clinical trials to prove their safety and efficacy, it costs less to develop them. Generic drugs are, therefore, cheaper. However, because the compounds in the generic versions have the same molecular structure as the brand-name version, their quality is essentially the same. Since they are cheap, people who can afford branded drugs don’t buy them believing them to be of inferior quality. Chemists have to hand out exactly what’s written on the prescription and most doctors except in government hospitals don’t hand out generic drugs.
  • Sahiwal:This cattle is considered to be one of the best milch cattle breed of India. The breed derives its name from Sahiwal area in Montgomery district of Punjab in Pakistan. These animals are also known as “Lambi Bar”, “Lola”, “Montgomery”, “Multani” and “Teli”.

Spearheaded by Bitcoin, blockchains achieve consensus among distributed nodes, allowing the transfer of digital goods without the need for centralized authorisation of transactions.
  • AFRS:It stands Automated Facial Recognition System use by police officers across the country was recommended on June 28,2019 by the National Crime Records Bureau (NCRB). AFRS works by maintaining a large database with photos and videos of peoples’ faces. Then, a new image of an unidentified person — often taken from CCTV footage — is compared to the existing database to find a match and identify the person. The artificial intelligence technology used for pattern-finding and matching is called “neural networks”. NCRB has proposed integrating this facial recognition system with multiple existing databases. The most prominent is the NCRB-managed Crime and Criminal Tracking Network & Systems (CCTNS). Facial recognition has been proposed in the CCTNS program since its origin.
  • Bhabha Kavach: It is the name of India’s first Lightest and indigenous Bullet Proof Jacket ‘from Ordnance Factory Board which recently received the nod of MHA. Developed by OFB and MIDHANI this state-of-the-art jacket can withstand 7.62mm hard steel core or bullets fired from an AK-47 rifle, 5.56mm INSAS bullet and even the recently decommissioned 7.65mm bullet of self-loading rifle (SLR). It is half KG lesser than the prescribed weight of MHA along with the 360 Degree Protection and has achieved the protection level of NIJ III+. Bhabha Kavach only weighs 9.2kg and is a major breakthrough for the Indian armed forces.

IRNSS would provide two types of services, namely Standard Positioning Services available to all users and Restricted Services provided to authorised users. ISRO is in talks with processing chip manufacturers such as Qualcomm to substitute the existing Global Positioning System (GPS) with the Indian version of satellite navigation. It is a regional system and so its constellation will consist of seven satellites. Three of these will be geostationary over the Indian Ocean, i.e., they will appear to be stationary in the sky over the region, and four will be geosynchronous – appearing at the same point in the sky at the same time every day. This configuration ensures each satellite is being tracked by at least one of fourteen ground stations at any given point of time, with a high chance of most of them being visible from any point in India.
  • JATAN:It is software for Digitization of Archaeological Museum. Human Centres Design and Computing Group has developed JATAN which is a virtual Museum software which is used for creating the digital collections in various museums and digital archival tools that are used in background for managing the National Portal and Digital Repository for Indian Museums.
  • Microdot technology:It involves spraying the body and parts of the vehicle or any other machine with microscopic dots, which give a unique identification. These microdot can be read physically with a microscope and identified with ultra violet light source. The microdots and adhesive will become permanent fixtures/affixation which cannot be removed without damaging the asset, which is the vehicle itself. The Ministry of Road Transport & Highways has issued a draft notification amending Central Motor Vehicle Rules, allowing motor vehicles and their parts, components, assemblies, sub-assemblies to be affixed with permanent and nearly invisible microdots.

  • SKA:Which stands for Square Kilometre Array is the name of the world’s largest radio telescope which the scientists at Cambridge recently finished brain designing. It consists of a supercomputer that will process the enormous amounts of data produced by the SKA’s telescopes. The total compute power will be around 250 PFlops — that’s 25 per cent faster than IBM’s Summit, the current fastest supercomputer in the world. When complete, the SKA will enable astronomers to monitor the sky in unprecedented detail and survey the entire sky much faster than any system currently in existence. The Square Kilometre Array (SKA) project is an international effort to build the world’s largest radio telescope, with eventually over a square kilometre (one million square metres) of collecting area. Whilst 10 member countries are the cornerstone of the SKA, around 100 organisations across about 20 countries are participating in the design and development of the SKA. Location of SKA antenna dishes will be built in South Africa (in the Karoo), with outstations in other parts of South Africa, as well as in eight African partner countries, namely Botswana, Ghana, Kenya, Madagascar, Mauritius, Mozambique, Namibia and Zambia. Another part of the telescope, the low-frequency array, will be built in Western Australia.
  • Athena and LISA: These are the two future missions of ESA which the researchers have proposed to combine the observing power to study the effects when two supermassive black holes collide. Currently in the study phase, both missions are scheduled for launch in the early 2030s. Athena will be the largest X-ray observatory ever built, investigating some of the hottest and most energetic phenomena in the cosmos with unprecedented accuracy and depth. LISA will be the first space-borne observatory of gravitational waves—fluctuations in the fabric of spacetime produced by the acceleration of cosmic objects with very strong gravity fields, like pairs of merging black holes.
  • Akash-MK-1S: It is the name of missile which was successfully test fired by India from the integrated test range at Chandipur in Odisha. The surface-to-air anti-aircraft missile with a strike range of 25 km and capability to carry warhead of 60 kg. Akash weapon system has combination of both command guidance and active terminal seeker guidance.
  • RISAT-2B :It is the name of country’s newest microwave Earth observation satellite which rode to its orbit 557 km above the ground recently. With the successful pre-dawn launch of RISAT-2B satellite, the Indian Space Research Organisation (ISRO) has added another feather to its cap. Data that will come from the all-weather day-and-night satellite are considered to be vital for the Armed Forces as also agriculture forecasters and disaster relief agencies. Dubbed as a ‘spy’ satellite, RISAT-2B (Radar Imaging Satellite-2B) will replace its predecessor RISAT-2 which has been actively used by India to monitor activities in terror camps across the border in Pakistan to thwart infiltration bids by terrorists.
  • DRDO :It recently conducted maiden test of an indigenously developed Hypersonic Technology Demonstrator Vehicle (HSTDV). HSTDV is an unmanned scramjet demonstration aircraft. HSTDV is dual-use technology and can have multiple civilian applications. It can be used for launching satellites at low cost and can also be available for long-range cruise missiles of future.
  • Data localization :It is the act of storing data on any device that is physically present within the borders of a specific country where the data was generated. Data localization is necessary for India for securing citizen’s data, data privacy, data sovereignty, national security, and economic development of the country. Recommendations by the RBI, the committee of experts led by Justice BN Srikrishna, the draft ecommerce policy and the draft report of the cloud policy panel show signs of data localisation. The extensive data collection by technology companies, has allowed them to process and monetize Indian users’ data outside the country. Therefore, to curtail the perils of unregulated and arbitrary use of personal data, data localization is necessary. Digital technologies like machine learning (ML), artificial intelligence (AI) and Internet of Things (IoT) can generate tremendous value out of various data. It can turn disastrous if not contained within certain boundaries. The Srikrishna Committee wants to localise data for law enforcement to have easy access to data, to prevent foreign surveillance, to build an artificial intelligence ecosystem in India, and because undersea cables through which data transfers take place are vulnerable to attacks.
  • Anthrax :It is a disease caused by Bacillus anthracis, a germ that lives in soil. It affects animals such as cattle, sheep, and goats more often than people. People can get anthrax from contact with infected animals, wool, meat, or hides. It can cause three forms of disease in people. Anthrax does not spread directly from one infected animal or person to another; it is spread by spores. These spores can be transported by clothing or shoes. Anthrax can be contracted in laboratory accidents or by handling infected animals or their wool or hides.
  • AWaRe :It is an online tool aimed at guiding policy-makers and health workers to use antibiotics safely and more effectively. The tool, known as ‘AWaRe’, classifies antibiotics into three groups: Access — antibiotics used to treat the most common and serious infections. Watch — antibiotics available at all times in the healthcare system. Reserve — antibiotics to be used sparingly or preserved and used only as a last resort. Antibiotic resistance is already one of the biggest health risks and is estimated to kill 50 million by 2050 worldwide. The threat continues to escalate globally because more than 50 per cent of antibiotics in many countries are used inappropriately such as for treatment of viruses when they only treat bacterial infections or use of the wrong (broader spectrum) antibiotic.
  • ICANN & NASSCOM :Internet Corporation for Assigned Names and Numbers (ICANN) and NASSCOM (National Association of Software and Services Companies) have announced collaboration for working in developing standards and identifier technology that will feed into the global consultation for managing Internet-of-Things (IoT) devices and infrastructure using internet. The Internet Corporation of Assigned Names and Numbers (ICANN) is a non-profit organization that was set up in 1998 to oversee the administration of domain names. ICANN coordinates and ensures the smooth and secure functioning of the cybernetic framework. The global nature of the Web today means that there are constantly increasing numbers of Domain Names, Host Names, IP addresses and web sites that are emerging on a daily basis. ICANN oversees this interconnected network and ensures that computers across the internet can find one another through defined unique pathways and identifiers.

  • 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.
  • Yeti:
    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.

  • 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 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.

  • 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.

  • 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.

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.
