This is true for all levels of teh IAS exam - prelims, mains and also the interview.This Week AffairsCurrent Affairs Quiz
Current Affairs in Science and Technology - June 2021
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.

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.

Recently, the scientists at ARCI and Sree Chitra Tirunal Institute of Medical Sciences (SCTIMST), Thiruvananthapuram, under the Department of Science & Technology (DST) have jointly developed new generation Iron-Manganese based alloys for biodegradable metal implants for use in humans.
The newly developed alloys are suitable for biodegradable stent and orthopedic implant applications.
Biodegradable materials like Fe, Mg, Zn, and polymer can participate in the healing process and then degrade gradually by maintaining the mechanical integrity without leaving any implant residues in the human body. According to the scientists, the newly developed alloys are alternatives to currently used metallic implants which remain permanently in the human body and can cause long-term side effects like systemic toxicity, chronic inflammation, and thrombosis.
TROGLOMYCES TWITTERI: It is a new species that has just been recently discovered using a Twitter image and thus has been named as Troglomyces twitteri. This new parasitic fungus was discovered by the biologist Sofia Reboleira of University of Copenhagen, Denmark while scrolling though Twitter where she stumbled upon a photo of a North American millipede shared by her US colleague Derek Hennen of Virginia Tech. There, she spotted a few tiny dots that struck her well-trained eyes.
Troglomyces twitteri: It is a type of parasitic fungus. It belongs to an order called Laboulbeniales. These tiny fungal parasites which look like tine larvae attack insects and millipedes. These fungi live on the outside of host organisms. In this case it was found living on the reproductive organs of millipedes. Laboulbeniales were first discovered in the middle of the 19th century.
Textiles Committee: It is a statutory body established in 1963 through an Act of Parliament and is under the administrative control of the Ministry of Textiles, Government of India.

Agappe Chitra Magna (ACM) Kit: It is a magnetic nanoparticle-based RNA extraction kit for use during testing for detection of COVID-19. The ACM kit is developed by the Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST) and manufactured by Kochi-based Agappe Diagnostics Ltd. It was validated by the National Institute of Virology and the approval of the kit was provided by the Central Drugs Standard Control Organization (CDSCO).
The ACM Kit uses an innovative technology for isolating RNA using magnetic nanoparticles to capture the RNA from the patient sample. The magnetic nanoparticle beads bind to the viral RNA and, when exposed to a magnetic field, give a highly purified and concentrated RNA. As the sensitivity of the detection method is dependent on getting an adequate quantity of viral RNA, this innovation enhances the chances of identifying positive cases.
Recently, the Government of India (GoI) announced the commercial launch of Agappe Chitra Magna. The commercial launch of the Made-In-India Medical kit seeks in helping to increase the rate of testing and bringing down its costs which is a crucial step for combating the pandemic. It will also reduce the dependence on imported kits and make COVID testing more cost-effective.
CACTus and CMEs:
Scientists have recently developed a new technique for tracking the huge bubbles of gas threaded with magnetic field lines that are ejected from the Sun, disrupting space weather and causing satellite failures, geomagnetic storms, and power outages.
The new technique will be used in India’s first solar mission Aditya-L1.
Coronal Mass Ejections (CMEs):
- The ejections from the Sun are technically called Coronal Mass Ejections (CMEs).
- These cause several disturbances to the space environment and thus forecasting their arrival time is very crucial.
- The forecasting accuracy is however hindered by limited CME observations in interplanetary space.
Computer Aided CME Tracking Software (CACTus):
- Computer Aided CME Tracking Software (CACTus) is a software-based on computer vision algorithm that was so far used to detect and characterize such eruptions automatically in the outer corona where these eruptions cease to show accelerations and propagate with an almost constant speed.
- However, due to the vast acceleration experienced by these eruptions, this algorithm could not be applied to the inner corona observations.
- This problem limited the capability to track the eruptions as CMEs accelerate in the lower corona.
- Furthermore, with the advancement in space technology, there has been a tremendous increase in the amount of data obtained from spacecraft.
- Thus, it can become a tedious task to identify and track the solar eruptions in a huge number of images if done manually.
CMEs Identification in Inner Solar Corona (CIISCO):
- Research led by Mr. Ritesh Patel, Prof. Dipankar Banerjee, and Dr. Vaibhav Pant from Aryabhatta Research Institute of observational sciences (ARIES), Nainital along with their collaborators from Royal Observatory of Belgium, has led to the development of an algorithm, CMEs Identification in Inner Solar Corona (CIISCO).
- CIISCO has been developed to detect and track the accelerating solar eruption in the lower corona.
- CIISCO was tested on various eruptions observed by space observatories, including Solar-Terrestrial Relations Observatory, PROBA2/SWAP, and Solar Dynamics Observatory launched by ESA and NASA, respectively.
- The parameters which are determined by CIISCO are helpful in characterizing these eruptions in the lower corona.
- When CIISCO will be implemented on the large volume of data available from space observatories, it will help in improving our understanding of eruptions in the inner corona.
- The research was published in the Solar Physics journal.
- Aditya-L1, the first solar mission of India, will observe the lower region of the solar corona. Thus, implementation of CIISCO on the Aditya-L1 data will provide new insight into the CME properties in this less explored region.
Science and Technology Empowered Committee:
A Science and Technology Empowered Committee for COVID-19 response have recently been constituted.
- This empowered committee has been constituted for manufacturing in high technology areas" in order to facilitate investments and promote manufacturing in technology-intensive sectors.
- The committee will be chaired by Vinod Paul (member, NITI Aayog) and K. Vijay Raghavan (Principal Scientific Adviser to the government).
- It said this committee would coordinate virus research among science agencies, scientists, industries and regulatory bodies.
- The Committee will work with the Department of Science & Technology (DST), Department of Biotechnology(DoB), Council of Scientific and Industrial Research (CSIR), Defence Research and Development Organization(DRDO) and Indian Institute for Science to take speedy decisions on research.
Plant-Insect Gene Transfer:
International teams led by researchers from the Chinese Academy of Agricultural Sciences in Beijing have recently identified the transfer of genes from plants to insects.
- Usually transfer of genes happen among the same family. For instance, the genes of a human parent get transferred to his or her child. However, this is not the case in the recent discovery.
- The Chinese scientists discovered that whiteflies use a plant gene to defend themselves against plant toxins.
About the Gene Transfer:
- The transfer of gene from one family to another is referred to as horizontal gene transfer. Here, in the recent discovery the transfer of gene is from the plant family to insect family.
- The Chinese scientists have found that the insect whiteflies use the stolen gene to degrade common toxins in plants.
- Plants use these toxins to defend themselves against insects.
- The incorporation of the plant gene in the whiteflies allow the insects to feed on the plants safely.
- The incorporated gene found was BtPMaT1.
- The whiteflies use this gene to neutralize the toxic compounds produced by the plants against them.
- According to the scientists, the whiteflies have incorporated the gene from the plants more than 35 million years ago.
- This is one of the main reasons why whiteflies still prevail as the major threat to agricultural crops. It is because of this that they have built a strong defence mechanism against the plants using this gene incorporation.
- Whiteflies are one of the major agricultural pests in the world.
- They are capable of attacking 600 different plants all over the world.
- Lately, these pests have acquired incredible adaptations to circumvent plant defences.
- Using this discovery, the Chinese scientists have now developed a strategy to counter back the super power of whiteflies.
- They have developed a new molecule that will interfere with the gene BtPMaT1.
Whiteflies Resistant Cotton:
- In 2020, the National Botanical Research Institute, Lucknow developed a Whiteflies resistant cotton variety.
- Cotton is one of the worst hit crops by whiteflies in India.
- Whiteflies are the greatest threat to agriculture in warm and tropical regions and also in green houses.
National Super Computing Mission (NSM):
India is fast emerging a leader in high power computing with the National Super Computing Mission (NSM).
- The NSM was launched to enhance the research capacities and capabilities in the country by connecting them to form a Supercomputing grid, with National Knowledge Network (NKN) as the backbone.
- The Mission is being jointly steered by the Department of Science and Technology (DST) and the Ministry of Electronics and Information Technology (MeitY).
- It is implemented by the Centre for Development of Advanced Computing (C-DAC), Pune, and the Indian Institute of Science (IISc), Bengaluru.
- This will include three systems of 3 Petaflops (PF) each and one system of 20PF as a national facility.
- Computing infrastructure has already been installed in four premier institutions and installation work is in rapid progress in 9 more.
- Completion in of Phase II of NSM in September 2021 will take the country’s computing power to 16 Petaflops (PF).
- Phase III, initiated this year, will take the computing speed to around 45 Petaflops.
- The three phases will provide access to High-Performance Computing (HPC) Facilities to around 75 institutions and more than thousands of active researchers, academicians working through Nation Knowledge Network (NKN) - the backbone for supercomputing systems.
List of supercomputers:
PARAM Shivay, the first supercomputer assembled indigenously, was installed in IIT (BHU), followed by PARAM Shakti, PARAM Brahma, PARAM Yukti, PARAM Sanganak at IIT-Kharagpur IISER, Pune, JNCASR, Bengaluru and IIT Kanpur respectively.
PARAM Siddhi - AI, the high-performance computing-artificial intelligence (HPC-AI) supercomputer, has achieved global ranking of 62 in TOP 500 most powerful supercomputer systems in the world, released on 16th November 2020.
Indian National Young Academy of Sciences (INYAS):
INYAS recently launched a multipronged nationwide mass awareness campaign to bust myths about Covid 19 vaccination programme.
The campaign will be carried out through COVACNEWS android-based mobile app.
- Indian National Young Academy of Sciences (INYAS) in the first and only recognized young scientist academy of India.
- It was founded by the Indian National Science Academy (INSA) council in 2014.
- Its vision is to promote Science education and networking among young scientists at National as well as International level.
Xenobots is the name given to new living robots that have been created using the stem cells of frogs by the scientists.
- The new creatures were designed on a supercomputer at UVM — and then assembled and tested by biologists at Tufts University
How were the Xenobots created?
- The scientists created Xenobots by micro engineering amphibian eggs with RNA.
- The biologists later removed the egg membrane after 24 hours.
- They then harvested the stem cell tissue from the embryo.
- The tissues then formed into spheres with tiny hair like structure called cilia.
- The cilia moved to propel the bots across a surface creating a Xenobot.
- Xenobots are made from frog cells.
- They have been named after the Xenopus laevis frog that supplied its cells to create the robot. Xenopus laevis is an African frog.
- These robots are to be used to detect diseases and deliver drugs to specific areas of the body.
- Xenobots are capable of healing themselves.
- They can record memories.
- Xenobots are less than 1 milli metre long.
- They are comprised of 500-1000 living cells.
- Xenobots come in different basic shapes and can scoot themselves in linear or circular directions.
- They are capable of joining up together to act collectively.
- They can move small objects by harnessing their cellular energy for a maximum of ten days.
How was the memory of the Xenobots created?
- The memory retaining capability of the Xenobots was propelled by a protein called EosFP.
- EosFP normally glows green. However, it emits red colour when exposed to a light of 390 nm wavelength.
- The cells of frog embryos with messenger RNA coding enabled the Xenobots to record when exposed to blue light (at around 390 nm of wavelength).
- The scientists tested the above function on ten Xenobots that were swimming around a surface where one spot was illuminated by the light of 390 nm of wavelength.
- After two hours, three of the bots emitted red light and the rest remained green. This provides a memory of their travel experience.
NASA's MARS ODYSSEY:
NASA's Mars Odyssey spacecraft marks 20 historic years of mapping red planet - Mars.
- NASA's Mars Odyssey spacecraft was launched 20 years ago on April 7.
- It has made it the oldest spacecraft still working at the Red Planet.
- The orbiter, which takes its name from Arthur C. Clarke's classic sci-fi novel "2001: A Space Odyssey", was sent to map the composition of the Martian surface in 2001 providing a window to the past so scientists could piece together how the planet evolved..
- Project Scientist Jeffrey Plaut of NASA's Jet Propulsion Laboratory in Southern California said that before Odyssey, we didn't know where water was stored on the planet.
- The feasibility of humans traveling to Mars was also the focus of an instrument aboard Odyssey that measured how much space radiation astronauts would have to contend with before it stopped working in 2003.
- The most complete global maps of Mars were made using Odyssey's infrared camera, called the Thermal Emission Imaging System, or THEMIS.
Rewaconodon Indicus: The Tiki Formation in Madhya Pradesh, a treasure trove of vertebrate fossils, has recently yielded a new species and two genera of cynodonts, small rat-like animals that lived about 220 million years ago.
- The researchers from the Indian Institute of Technology Kharagpur, used scanning electron microscopy to study about 10 teeth samples collected from the village of Tihki in Shahdol District, Madhya Pradesh.
- The results showed that they had found a new species, and they named it Rewaconodon indicus, indicating India, the country it was discovered from.
- The team also identified two new genera from the area.
- The first was named Inditherium floris, after India and the Latin word therium meaning beast. As the teeth had a flower-shaped crown, it earned the species name floris.
- The second was named Tikiodon cromptoni, after Tiki Formation and Greek word odon meaning tooth. The species name is after paleontologist A.W. Crompton.
- The Tiki Formation is a Late Triassic geologic formation in Madhya Pradesh.
- Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
- Phytosaur remains attributable to the genus Volcanosuchus have also been found in the Tiki Formation.
- The genera Tikiodon, Tikitherium and Tikisuchus and species Rewaconodon tikiensis, Hyperodapedon tikiensis and Parvodus tikiensis have been named after the Tiki Formation.
Disc-footed bat: Meghalaya has recently yielded India’s first bamboo-dwelling bat with sticky discs.
- The disc-footed bat (Eudiscopus denticulus) was recorded in Meghalaya’s Lailad area near the Nongkhyllem Wildlife Sanctuary, about 1,000 km west of its nearest known habitat in Myanmar.
- The disc-footed bat has raised Meghalaya’s bat count to 66, the most for any State in India.
- It has also helped add a genus and species to the bat fauna of India.
Whitest Paint: Engineers from Purdue University in the US have recently created what they are calling the whitest paint yet.
Buildings coated with this paint may be able to cool them off enough to reduce the need for air conditioning.
About the Whitest Paint:
- The team of researchers at the university created an ultra-white paint in October pushing the limits of how white paint can be.
- The older formulation was made of calcium carbonate, while the new one is made up of barium sulphate, which makes it whiter.
- The newer paint not only is whiter but also can keep surfaces cooler than the formulation that the researchers had previously demonstrated.
- If this new paint was used to cover a roof area of 1,000 square feet, it may be able to get a cooling power of 10 kilowatts.
- Typical commercial white paint gets warmer rather than cooler and that paints currently available in the market that are designed to reject heat reflect only 80-90 per cent of the sunlight and therefore, they can’t make surfaces cooler than their surroundings.
- The team has also claimed that this paint may be the closest equivalent to the blackest black paint called “Vantablack” that is able to absorb up to 99.9 per cent of visible light.
What makes the whitest paint so white?
Two features give the paint its extreme whiteness.
- The first feature is the paint’s very high concentration of a chemical compound called barium sulfate, which is also used to make photo paper and cosmetics white.
- The second feature is that the barium sulfate particles are all different sizes in the paint. How much each particle scatters light depends on its size, so a wider range of particle sizes allows the paint to scatter more of the light spectrum from the sun.
Absorption of light by different colours:
- One needs to note that whenever an object is seen by the eye, it is either because of sunlight or the artificial light in the room.
- This light is made up of seven different colours (Violet, Indigo, Blue, Green, Yellow, Orange and Red or VIBGYOR).
- Specifically, light is made up of wavelengths of different colours.
- For Example: If an individual is looking at a sofa that is green, this is because the fabric or material it is made up of is able to absorb all the colours except green.
- It implies that the molecules of the fabric reflect the green coloured wavelengths, which is what the eye sees.
- Therefore, the colour of any object or thing is determined by the wavelength the molecules are not able to absorb.
What determines which wavelength of light will be reflected and absorbed?
- The determination of which wavelength of light will be reflected and absorbed is dependent on how electrons are arranged in an atom (the building block of life, an atom is made up of electrons, protons and neutrons.
- These three particles make up everything that exists in the universe.
- In contrast, if an object is black, it is because it has absorbed all the wavelengths and therefore no light is reflected from them.
- This is the reason that darker objects, as a result absorbing all wavelengths tend to heat up faster (during absorption the light energy is converted into heat energy).
DuroKea Series: Union Minister of Education Ramesh Pokhriyal ‘Nishank’ virtually launched “World 1st affordable and long-lasting hygiene product DuroKea Series”, developed by IIT Hyderabad researchers.
- The researchers have developed innovative DuroKea long-lasting technologies to combat COVID-19 virus spreading.
- This next generation DuroKea antimicrobial technology starts at Rs. 189.
- It kills 99.99% of germs instantly and leaves behind the long-lasting protective nanoscale coating up to 35 days till next wash.
- The unique property of DuroKea range is to ensure instant killing (within 60 sec) and prolonged protection which is an immense necessity during this current pandemic situation.
- This revolutionary antimicrobial property of DuroKea products has been tested and certified by Indian Government accredited lab and field-tested at the IIT Hyderabad campus.
Space Station Crew-2 Mission With Four Astronauts Launched: Four astronauts were recently launched to the International Space Station (ISS) from Florida as part of collaboration between NASA and SpaceX under the Commercial Crew Program.
- The mission is called Crew-2 and is the second crew rotation of the SpaceX Crew Dragon and the first with international partners.
- Out of the four astronauts, two are from NASA and two are from the Japan Aerospace Exploration Agency (JAXA) and the European Space Agency (ESA).
- Shane Kimbrough and Megan McArthur from NASA will serve as the mission’s spacecraft commander and pilot, while Akihiko Hoshide and Thomas Pesquet will serve as mission specialists to the space station for a six-month science mission.
- Earlier, in May 2020, NASA’s SpaceX Demo-2 test flight lifted off for the ISS carrying astronauts Robert Behnken and Douglas Hurley.
- The aim of this test flight was to see if SpaceX capsules could be used on a regular basis to ferry astronauts to and from the ISS.
- Demo-2 was followed by the Crew-1 mission in November, which was the first of six crewed missions between NASA and SpaceX marking the beginning of a new era for space travel.
- Now, Crew-2 astronauts will join the members of Expedition 65. They will stay aboard the ISS for six months during which time they will conduct science experiments in low-Earth orbit.
- Their central focus during this time will be to continue a series of Tissue Chips in Space studies.
What are Tissue Chips?
- Tissue Chips are small models of human organs that contain multiple cell types that behave similarly to the human body. According to NASA, these chips can potentially speed up the process of identifying safe and effective drugs and vaccines.
About Commercial Crew Program:
- Development of the Commercial Crew Program began in the second round of the Commercial Crew Development program, which was rescoped from a technology development program for human spaceflight to a competitive development program that would produce the spacecraft to be used in the Commercial Crew Program.
- The main goal of this program is to make access to space easier in terms of its cost, so that cargo and crew can be easily transported to and from the ISS, enabling greater scientific research.
- Through this program, NASA plans to lower its costs by sharing them with commercial partners such as Boeing and SpaceX, and also give the companies incentive to design and build the Commercial Orbital Transportation Services (COTS).
- Secondly, by encouraging private companies such as Boeing and SpaceX to provide crew transportation services to and from low-Earth orbit, NASA can focus on building spacecraft and rockets meant for deep space exploration missions.
Unicorn: Scientists have discovered what may be the smallest-known black hole in the Milky Way galaxy and the closest to our solar system.
- The researchers have nicknamed it Unicorn.
- They said that the black hole is roughly three times the mass of our sun, testing the lower limits of size for these extraordinarily dense objects that possess gravitational pulls so strong not even light can escape.
- A luminous star called a red giant orbits with the black hole in a so-called binary star system named V723 Mon.
- The black hole is located about 1,500 light years - the distance light travels in a year, 5.9 trillion miles (9.5 trillion km) - from Earth. While it may be the closest one to us, it is still far away. By way of comparison, the closest star to our solar system, Proxima Centauri, is 4 light years away.
- Black holes like this one form when massive stars die and their cores collapse.
- The study is published in the Monthly Notices of the Royal Astronomical Society.
- The astronomers have named it Unicorn because V723 Mon is in the Monoceros constellation, which translates to unicorn, and partly because it is a very unique system" in terms of the black hole's mass and relative closeness to Earth.
What is a black hole?
A black hole is a place in space where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
There are three categories of black holes.
- The smallest, like 'the Unicorn,' are so-called stellar-mass black holes formed by the gravitational collapse of a single star.
- There are gargantuan 'supermassive' black holes like the one at our galaxy's center, 26,000 light-years from Earth, which is four million times the sun's mass.
- A few intermediate-mass black holes also have been found with masses somewhere in between.
MOXIE: The Perseverance rover of Mars 2020 Mission of NASA recently converted carbon dioxide into oxygen.
- This is for the first time that this has been achieved in another planet.
- This was achieved by MOXIE, an instrument placed in the front side of the rover.
- The Mars Oxygen In-Situ Resource Utilization Experiment is better known as MOXIE.
- MOXIE was designed by the Massachusetts Institute of Technology (MIT).
- It is also called “Mechanical Tree” because, it uses electricity and chemistry to split carbon molecules into carbon and oxygen. In due process, it produces carbon monoxide as a byproduct.
- It is capable of generating ten grams of oxygen in one hour.
- It produced five grams of oxygen in its first run. It is equal to ten minutes of breathable oxygen for an astronaut performing a normal activity.
- It was built with nickel-alloy. The alloy is heat-resistant and is designated to tolerate temperatures of 1,470 degrees Fahrenheit.
- It was covered with gold coating so that the heat radiated does not harm the rover.
- According to the scientists at MIT, one ton version of MOXIE is capable of producing twenty-five tonnes of oxygen.
Note: Earlier missions have proved the presence of ice in Mars.
Scientists believe that extracting oxygen from the Martian atmosphere, that is rich in carbon dioxide is more feasible than extracting oxygen from ice that is present in its under surface.
Perseverance carrying the Ingenuity helicopter landed on Mars on February 18, 2021. The helicopter recently made its successful flight. This was first flight in another planet.
Mars Mission- Ingenuity: Recently, NASA successfully flew its tiny experimental helicopter Ingenuity on Mars, the first powered flight on another planet and a feat a top engineer called "our Wright brothers' moment."
Data and images from the autonomous flight were transmitted 173 million miles (278 million kilometres) back to Earth where they were received by NASA’s array of ground antennas and processed more than three hours later.
- More than six years in the making, Ingenuity is just 19 inches (49 centimeters) tall, a spindly four-legged chopper.
- Its fuselage, containing all the batteries, heaters and sensors, is the size of a tissue box.
- The carbon-fiber, foam-filled rotors are the biggest pieces: Each pair stretches 4 feet (1.2 meters) tip to tip.
- Ingenuity also had to be sturdy enough to withstand the Martian wind, and is topped with a solar panel for recharging the batteries, crucial for surviving the minus-130 degree Fahrenheit (minus-90 degree-Celsius) Martian nights.
- Ingenuity was on autopilot for its entire flight, out of sight, direct control, or contact with the men and women on Earth who had ordered it aloft—because radio signals take too long to travel between the planets for any human operator to intervene.
- The mini 4-pound (1.8-kilogram) copter even carried a bit of wing fabric from the Wright Flyer that made similar history at Kitty Hawk, North Carolina, in 1903.
- NASA 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 acting administrator of NASA is Steve Jurczyk.
- Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, being larger than only Mercury.
- Mars is sometimes called the Red Planet. It's red because of rusty iron in the ground. Like Earth, Mars has seasons, polar ice caps, volcanoes, canyons, and weather.
- It has a very thin atmosphere made of carbon dioxide, nitrogen, and argon.
- Mars is named for the ancient Roman god of war. The Greeks called the planet Ares (pronounced Air-EEZ). The Romans and Greeks associated the planet with war because its color resembles the color of blood.
- Mars has two small moons.
Single Crystal Blades Technology: In a major technological breakthrough, the Defence Research and Development Organisation (DRDO) on Monday said it has developed single crystal blade technology and it has supplied 60 of them to the Hindustan Aeronautics Limited (HAL) for the company’s indigenous helicopter development program for helicopter engine application.
- It is part of a programme taken up by the Defence Metallurgical Research Laboratory (DMRL), a laboratory of the DRDO.
- The DRDO will develop total five sets 300 in number, of single crystal high pressure turbine (HPT) blades using a nickel-based super alloy.
- They supply of other 4 sets will be completed in due course.
- This single crystal blades technology has been developed by the Defence Metallurgical Research Laboratory (DMRL), one of the DRDO’s laboratories.
- A few countries such as the US, the UK, France and Russia have the capability to design and manufacture single crystal components.
What is the use of single crystal blades in helicopters?

Tianhe space station core module: China, on April 29, 2021, launched the Tianhe space station core module of its Space Station.
It is the latest in Beijing's increasingly ambitious space programme.
- The module that was launched is called Tianhe.
- The Space Station China is building is called Tiangong.
- China kick started the series of key launch missions that aim to complete the construction of the station by the end of next year.
- The Long March-5B Y2 rocket, carrying the Tianhe module, blasted off from the Wenchang Spacecraft Launch Site on the coast of the southern island province of Hainan.
- The launch begins the first of 11 missions necessary to construct and provision the station and send up a three-person crew by the end of next year.
- The astronauts will live on the station for six months at a time.
- Tianhe has a total length of 16.6 meters, a maximum diameter of 4.2 meters and a take-off mass of 22.5 tonnes, and is the largest spacecraft developed by China.
- The Tianhe module will act as the management and control hub of the space station Tiangong
- Tiangong means “Heavenly Space”.
- It is to begin its operations in 2022.
- Still 11 more modules are to be launched and assembled to complete the space station.
- According to the Chinese Government, the completed Space Station will look like the “Mir Station”. Mir was a Russian Space Station that orbited between 1980s and 2001.
- The Chinese Space Station, Tiangong will orbit the earth in the low earth orbit at a height of 400 to 450 kilometres.
- The lifespan of the space station is 15 years.
- It weighs more than 90 tonnes.
- The size of Tiangong Space Station will be a quarter the size of the International Space Station.
- The station is also expected to contribute to the peaceful development and utilisation of space resources through international cooperation, as well as to enrich technologies and experience for China's future explorations into deeper space.
- The Chinese space station was expected to be a competitor to the aging International Space Station (ISS) which is a modular space station in low Earth orbit.
- After International Space Station retires, Tiangong will be the only space station orbiting the earth.
International Space Station (ISS):
- The International Space Station (ISS) is a multinational collaborative project involving five participating space agencies which included NASA, (US), Roscomos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada).
- It is due to be retired after 2024, although NASA has said it could potentially remain functional beyond 2028.
Note: Russia has planned to launch its own space station in 2025.
Previous Chinese Mission
- In 2011, Chinese launched the Tiangong – 1. It was the first prototype module that laid groundwork for the permanently crewed station.
- In 2016, the second lab Tiangong – 2 was launched.
China's Lunar Missions
- The Chinese are also planning to build a separate lunar space station with Russia. This space station might either be placed in the orbit of the moon or on its surface.
- China's space programme has also recently brought back the first new lunar samples in more than 40 years and expects to land a probe and rover on the surface of Mars later next month.
‘NEO-01’ Clear Space Debris: The Chinese government has recently launched a robot prototype named as ‘NEO-01’, in the Earth’s low orbit, on its Long March 6 rocket.
- The 30kg robot prototype has been developed by Shenzhen-based space mining start-up ‘Origin Space’.
- The NEO-01, will also peer into deep space to observe small celestial bodies, was launched on along with a handful of satellites.
- It will pave the way for future technologies capable of mining on asteroids.
- Since the establishment of the world's first asteroid mining company Planetary Resources in 2009, more than a dozen firms across the world have entered the fledging sector, including 3D Systems of the United States and Japan's Astroscale.
- Unlike Astroscale's technology, which uses magnets to gather up space junk, NEO-01 will use a net to capture debris and then burn it with its electric propulsion system,
- China's main objective is to observe small celestial bodies in deep space and to experiment with space debris removal techniques.
- NEO-01 will use a large net to capture debris left behind by other spacecraft and then burn it using its electric propulsion system.
Zhurong: China has recently named its first-ever Mars rover “Zhurong” after an ancient fire god ahead of a landing attempt on the Red Planet in May.
The China National Space Administration (CNSA) revealed the name at the sixth China Space Day held in Nanjing.
The Chinese name for Mars, “Huoxing,” literally means “fire star.”
- Zhurong was the most popular of 10 shortlisted names for a public vote that opened in January, and that choice was backed by an expert panel and the CNSA itself.
- The rover carries panoramic and multispectral cameras and instruments to analyze the composition of rocks.
- Zhurong will also investigate subsurface characteristics with ground-penetrating radar if all goes according to plan.
Uranium-214: The scientists have recently created lightest form of Uranium.
The new found uranium is called the Uranium-214.
The researchers created the new uranium isotope at the Heavy Ion Research Facility in Lanzhou, China.
The discovery could reveal more about a weird alpha particle that gets ejected from certain radioactive elements as they decay.
- Uranium-214 is an isotope, or a variant of the element, with 30 more neutrons than protons, one fewer neutron than the next-lightest known uranium isotope.
- Neutrons have mass.
- The recently found uranium-214 is much lighter than more common uranium isotopes.
- This includes uranium-235, which is used in nuclear reactors and has 51 extra neutrons.
- It had a half-life of just half a milli-second. The half life of a radioactive sample is the time taken for half of the radioactive sample to decay.
- The most common isotope of uranium — called uranium-238.
- It has a half-life of about 4.5 billion years, which is about the age of Earth.
- This newfound isotope isn't just lighter than others, but it also showed unique behaviors during its decay.
- As such, the new findings will help scientists better understand a radioactive decay process known as alpha decay, in which an atomic nucleus loses a group of two protons and two neutrons — collectively called an alpha particle.
Note: The alpha particles are those particles that get ejected from radioactive elements as they decay.
- However, though scientists know that alpha decay results in the ejection of this alpha particle, after a century of study but they still don't know the exact details of how the alpha particle is formed before it gets ejected.
How was Uranium-214 created?
- A beam of Argon was projected on Tungsten inside a machine called a gas-filled recoil separator — in this case the Spectrometer for Heavy Atoms and Nuclear Structure, or SHANS.
- The researchers then added protons and neutrons to the material through a LASER beam to create Uranium-214.
- The scientists found that protons and neutrons of Uranium-214 interacted much more strongly than in isotopes with similar number of neutrons and protons.
- In other words, nuclear force in Uranium-214 was greater than the nuclear force in other isotopes.
8 extremely rare 'millisecond pulsars' discovered inside globular clusters
Millisecond pulsars: An international team of astronomers have recently discovered eight millisecond pulsars.
These pulsars were located within the dense clusters of stars, known as "globular clusters," using South Africa's MeerKAT radio telescope.
About Milli second Pulsars:
- Millisecond pulsars are neutron stars.
- They are extremely compact stars mainly made up of neutrons, and are amongst the most extreme objects in the universe.
- They pack hundreds of thousands of times the mass of the Earth in a sphere with a diameter of about 24 km.
- They spin at a rate of hundreds of rotations per second.
- They emit a beam of radio waves that are detected by the observer at every rotation, like a lighthouse.
- The formation of these objects is highly enhanced in the star-rich environments at the centers of globular clusters.
About the discovery:
- The Pulsar discovery comes from two international collaborations TRAPUM and MeerTIME.
- This is the first pulsar discovery using the MeerKAT antennas.
- Ridolfi and his colleagues used the MeerKAT telescope — an array of 64 individual satellite dishes run by the South African Radio Astronomy Observatory (SARAO).
- The astronomers directed the telescope towards nine globular clusters and they discovered new pulsars in six of them. Of these, six of them orbit around another star.
- The discovery will help the Globular Cluster Pulsar Survey of TRAPUM.
- MeerKAT Telescope
- It is a Karoo Array telescope with sixty-four antennas.
- It is also a radio telescope.
- It is located in the Northern Cape of South Africa.
- It is soon to be expanded to MeerKAT+ by installing twenty more antennas.
Mapping of Osteocytes: The researchers from the Garvan Institute of Medical Research have mapped the unique genetic profile of the skeleton's 'master regulator' cells, known as Osteocytes for the first time.
- The study published today in Nature Communications.
Key Findings of the study:
- The researchers have outlined the genes that are switched on and off in osteocytes.
- This will help in diagnosing bone diseases that have genetic component.
- For the first time, the researchers have pictured the whole landscape of osteocytes.
- They have found that majority of the genes that are active within osteocytes had no role in bones.
- This means that they only give commands.
- This discovery will help to understand what controls the skeleton actually.
- Osteocytes are the longest living bone cell, making up 90–95% of cells in bone tissue in contrast to Osteoclasts and Osteoblasts making up ~5% (40).
- They are oblate shaped bone cells.
- They are found in bone tissues.
- They live as long as the organism lives.
- There are more than 42 billion Osteocytes in human body.
- The Osteocytes do not divide.
- Their average half life is 25 years.
- The skeleton of the humans keeps changing structurally throughout his life.
- Osteocytes are the most abundant cell present in bones.
- Osteocytes form when osteoblasts become buried in the mineral matrix of bone and develop distinct features.
- These osteocytes form a network similar to the neurons in the brain.
- There are more than 23 trillion connections between 42 billion osteocytes.
- This network is responsible for monitoring bone health.
- It responds to ageing.
- They also send signals to other cells in the bone to build or break down an old bone.
- The diseases such as osteoporosis are caused due to imbalance in these processes.
Development of Bones:
- During Bone formation Osteoblast is left behind.
- Osteoblasts are cells that synthesize bones.
- The process of bone formation is still not known completely.
Mucormycosis-Black Fungus Infection in COVID: Mucormycosis, also known as black fungus infection is increasing among the COVID patients.
- The National COVID Task Force recently issued an advisory against Mucormycosis.
- This disease is rare but recently this disease has been increasing among COVID patients in Delhi, Gujarat and Maharashtra.
What is Mucormycosis?
- Mucormycosis sometimes also called zygomycosis is a disease that mainly affects the skin, lungs and brain.
- It is rare fungal infection.
- It is caused by a group of molds called Mucoromycetes which are found in soil, leaves, or rotting woods.
- The fungus can enter the body through breathing, open wounds or cuts.
- It mainly affects people who are on medication.
- The lungs or sinuses of the recovering COVID patients get affected after they inhale fungal spores from the air.
- However, it is not a major threat to those with a healthy immune system.
- It causes redness around the eyes, nose.
- Also, the person suffers from headache, fever, bloody vomits, shortness of breath, altered mental status.
- Mucormycosis is suspected when a person suffers from sinusitis, local pain on cheek bone, blackish discoloration over bridge of nose, chest pain, thrombosis, plural effusion, necrosis, blurred vision, etc.
How can it be diagnosed?
- You should see a doctor if you are experiencing the above symptoms post the COVID recovery.
- A definite diagnosis will be made by the identification of fungi in the patient's tissue.
- For this, a doctor may collect a sample of your nasal discharge.
- Mucormycosis might lead to loss of eyes or upper jaws.
- Such patients might require a surgery.
- The treatment of Mucormycosis includes infusion of saline, Amphotericin and other anti-fungal therapies.
Task Force Advisory:
- Advisory goes on to say that Mucormycosis, if uncared for, may turn fatal.
- To prevent disease, blood glucose level should be monitored post-Covid discharge
- The COVID Task Force has recommended to control hyperglycemia after discharge.
Why are COVID patients susceptible to Mucormycosis?
- The immunity level of a person recovering from COVID-19 is very low.
- The Mucoromycetes easily affects persons with very low immunity levels.
- It is especially common among COVID patients who are treated with steroids to reduce inflammation.
- Inflammation is a condition where a part of the body is swollen, reddened and is often painful due to an infection or reaction to injury.
OSIRIS-REx: The NASA Spacecraft called the “Osiris-Rex” has started a two year long journey back to the earth.
- The spacecraft reached asteroid Bennu in 2018.
- It then spent two years flying around it and collected rubbles.
Note: Rubbles are rough fragments of brick, stones.
- It will be the biggest cosmic haul for the U.S. since the Apollo moon rocks.
- While NASA has returned comet dust and solar wind samples, this is the first time it's gone after pieces of an asteroid.
- Japan has accomplished it twice, but in tiny amounts.
About the OSIRIS-Rex:
- The mission launched to study asteroid Bennu spent 2.5 years mapping its surface.
- In 2020, the scientists directed Osiris Rex to drop down and collect sixty kilo grams of regolith (top soil).
- They also found that the asteroid has lots of accessible water.
- The mission will help to understand the origin and evolution of solar system.
- Bennu — considered a broken chunk from a bigger asteroid — is believed to hold the preserved building blocks of the solar system.
- It is the most hazardous asteroids currently known to the earth. Meaning it has one in 2,700 chances of hitting the earth in the late 22nd century.
- It makes its closest approach to the earth once in six years.
- The size of Bennu also makes it approachable.
- Most of the asteroids spin very fast. This rapid spinning makes it difficult for the spacecrafts to collect samples.
- The returning pieces could shed light on how the planets formed and how life arose on Earth.
- They also could improve Earth’s odds against any incoming rocks.
However, Bennu is not the first mission on an asteroid.
- Japan had sent Hayabusa.
- It was launched in 2014 to collect samples from Ryugu.
- It reached Ryugu in 2018.
- It spent 18 months there and returned to the earth in December 2020.
- European Space Agency had sent Rosetta Mission to explore comet Churyumov-Gerasimenko in 2004.
- It was the first mission to orbit a comet.
- It was also the first mission to land a probe on its surface.
Smokeless Cremation: Indian Institute of Technology (IIT), Ropar has recently developed a prototype of a moveable electric cremation system.
This system is claimed to be using first of its kind technology that involves smokeless cremation despite using wood.
The cart has been developed in collaboration with a company Cheema Boilers Limited
About the system:
- The moveable electric cremation system uses half of the wood otherwise required for the cremation and still is eco-friendly because of the technology that uses combustion air system.
- It is based on wick-stove technology in which the wick when lighted glows yellow.
- This is converted into smokeless blue flame with the help of combustion air system installed over the wicks.
- The cremation system or incinerator heats up at 1044 degree Celsius which ensures complete sterilization.
Keeping in view the present pandemic situation if this system is adopted, then it may provide respectable cremation to the near and dear ones of those who cannot afford the financial burden of arranging wood.

- As United States (US) had imposed sanctions on Iran and the doors of business is completely closed to the country.
- The US had imposed anti terrorism trade sanctions and has been trying to slow down its nuclear programme for decades.
- Therefore, Iran must have got the US chips used in supercomputers illegally.
- Iran is using bitcoin mining facilities to buy required raw materials from US and other countries.
- Most of these are illegal under the sanctions imposed against the country.
In 2001, the Amirkabir University developed a 32-node PC based on Intel Pentium processors.
Again in 2007, the country had its hands on 216 AMD cores which in turn led to the most powerful supercomputer of all time.
- Iran also called Persia, and officially the Islamic Republic of Iran is a country in Western Asia.
- It is bordered to the northwest by Armenia and Azerbaijan,to the north by the Caspian Sea, to the northeast by Turkmenistan, to the east by Afghanistan and Pakistan, to the south by the Persian Gulf and the Gulf of Oman, and to the west by Turkey and Iraq.
- Its central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz, give it geostrategic importance.

Lunar Eclipse 2021: The First lunar eclipse of 2021 will take place on May 26, 2021.
- The moon on its journey around the earth will be passing through the earth’s shadow and will be totally eclipsed
- On May 26 evening, a rare celestial event will unfold its mesmerizing act when a Super Blood Moon will be seen in the eastern sky, just after a total lunar eclipse.
- It will be a super lunar phenomenon because three major events will be taking place all at once, namely 'Supermoon', 'Red Blood Moon' and a Lunar Eclipse.
- In India, the eclipse will only be visible partially at a few places in the eastern parts of the country while it will be best seen from Australia, parts of the United States, western South America, the Pacific and South-East Asia.
What’s a super moon?
- A super moon occurs when a full or new moon coincides with the moon’s closest approach to the Earth.
- The Moon’s orbit around Earth is not perfectly circular.
- This means the Moon’s distance from Earth varies as it goes around the planet.
- When full or new moon coincides with perigee of Moon to the Earth, super moon event occurs.
Note: The closest point in the orbit, called the perigee.
- A full moon that happens near the perigee is called a super moon because close proximity of moon makes it bigger and brighter in appearance than usual. Though, difference between super and normal moon is hard to notice.
What is lunar eclipse?
- A lunar eclipse happens when the Earth’s shadow covers all or part of the Moon.
- This event only happens during full moon.
- Lunar eclipse happens twice a year during which, moon comes in same horizontal plane as the Earth and Sun.
What is a full moon?
- When Moon and Sun are on opposite sides of Earth, full moon happens.
- This makes it possible to observe entire lit-up side of the moon.
What is a blood moon?
When moon gets completely covered by Earth’s shadow, it appears dark.
It does not get completely black but appears red. Because of this red colour, total lunar eclipses are called as red or blood moons.
Why does the moon appear red?
- Sunlight contains all colors of visible light.
- The particles of gas that make up Earth’s atmosphere are more likely to scatter blue wavelengths of light while redder wavelengths pass through.
- This is called Rayleigh scattering, and it’s why the sky is blue and sunrises and sunsets are often red.
- In the case of a lunar eclipse, red light can pass through the Earth’s atmosphere and is refracted – or bent – toward the moon, while blue light is filtered out.
- This leaves the moon with a pale reddish hue during an eclipse.
Smart Window Material: Indian Institute of Technology Guwahati (IIT Guwahati) researchers have recently developed smart window materials for automatic climate control of buildings.
- Such smart window materials would help in Climate control.
- The smart window material has been developed by Dr. Debabrata Sikdar, Assistant Professor in Electronics and Electrical Engineering department at IIT Guwahati along with his research scholar Ashish Kumar Chowdhary.
- According to the researchers, the smart window material designed by them can effectively control the amount of heat and light passing through it in response to an applied voltage and would ultimately help in developing efficient automatic climate control.
- The results of their study have recently been published in the journal, Solar Energy Materials and Solar Cells.
- The reason for developing this window was that there has been increased attention to sustainable architectural designs for better light and heat management in buildings in recent years, and deploying smart windows is the first step for such structures.
About Smart Windows:
- The design of smart windows is suitable for all-weather conditions.
- Smart window glasses have been designed using noble metals which can dynamically control the solar radiations.

A team of Scientists from Jawaharlal Nehru Centre for Advanced Scientific Research, an autonomous institute of the Department of Science & Technology (DST), Government of India (GoI) have found a method to mimic nature’s own process of reducing carbon dioxide in the atmosphere, namely photosynthesis, to capture excess carbon dioxide in the atmosphere.
The scientists from JNCASR designed and fabricated an integrated catalytic system based on a metal-organic framework (MOF-808).
The system comprising of a photosensitizer (molecules which absorb light and transfer the electron from the incident light into another nearby molecule) can harness solar power and a catalytic centre that can eventually reduce CO2.
The artificial photosynthesis (AP) method harnesses solar energy and converts the captured carbon dioxide to carbon monoxide (CO).
Then this CO can be used as a fuel for internal combustion engines.
The work described above has been accepted for publication in the journal ‘Energy& Environmental Science’ of Royal Society of Chemistry, UK.
Photosensitizers are molecules which absorb light (hν) and transfer the energy from the incident light into another nearby molecule.
It is chemically called “ruthenium bipyridyl complex ([Ru(bpy)2Cl2])”.
It also comprises of a catalytic part called rhenium carbonyl complex ([Re(CO)5Cl]).
Both of the molecular entities lie in the close proximity and are confined to a nano-space of the porous metal-organic framework system.
This helps in absorbing the CO2 at room temperature.
The catalyst has the capability to oxidize the water in order to produce oxygen.
This photocatalytic assembly is when assessed to reduce the CO2 under direct sunlight under a water medium, it produces CO.
About Artificial Photosynthesis:
Artificial photosynthesis is a chemical process that biomimics the natural process of photosynthesis to convert sunlight, water, and carbon dioxide into carbohydrates and oxygen.
The term artificial photosynthesis is commonly used to refer to any scheme for capturing and storing the energy from sunlight in the chemical bonds of a fuel (a solar fuel).
Photocatalytic water splitting converts water into hydrogen and oxygen and is a major research topic of artificial photosynthesis.
Light-driven carbon dioxide reduction is another process studied that replicates natural carbon fixation.
Difference between Natural photosynthesis and Artificial photosynthesis:
Natural photosynthesis is very inefficient in terms of solar-to-biomass conversion.
Artificial photosynthesis short-circuits the natural process by utilizing the most energetically efficient primary events of light capture, charge separation and charge transfer.
Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) is a multidisciplinary research institute located at Jakkur, Bangalore, India.
It is an autonomous institute which was established by the Department of Science and Technology (DST) of the Government of India, to mark the birth centenary of Pandit Jawaharlal Nehru.
Pt. Jawaharlal Nehru was the first prime minister of independent India.
State-owned Indian Oil Corporation Ltd. has recently entered into a joint venture with Israel-based battery technology startup Phinergy to develop aluminium-air technology based battery systems for electric vehicles and stationary storage, as well as hydrogen storage solutions.
IOC Phinergy Private Limited is an Israeli start-up company specialising in hybrid lithium-ion and aluminium-air.
Top automakers, including Ashok Leyland and Maruti Suzuki have already signed letters of intent with the newly formed joint venture to commercially deploy the battery solutions produced by IOC Phinergy.
Aluminium-air batteries are said to be a lower cost and more energy-dense alternative to lithium-ion batteries which are currently in widespread use for electric vehicles in India.
Aluminium-air batteries utilise oxygen in the air which reacts with an aluminium hydroxide solution to oxidise the aluminium and produce electricity.
The joint venture will manufacture Aluminum-Air systems in India to boost India's flagship programme - "Make in India" and recycle used Aluminum to strengthen India's energy security.
Aluminium-air battery-based electric vehicles are expected to offer much greater range of 400 km or more per battery compared to lithium-ion batteries which currently offer a range of 150-200 kilometres per full charge.
The aluminium plate in an aluminium-air battery is converted into aluminium trihydroxide over time and that aluminium can be reclaimed from aluminium trihydroxide or even traded directly for industrial uses.
Aluminium-air based batteries are also expected to be significantly cheaper than lithium-ion batteries, thereby reducing the cost of electric vehicle.
The joint venture aims to help India in its journey towards clean, sustainable, affordable, safe, and long-lasting energy options and facilitate much faster adoption of e-Vehicles in the country.
One of the key downsides of aluminium-air batteries is that they cannot be recharged like lithium-ion batteries.Therefore, large scale use of aluminium-air battery based vehicles would require the wide availability of battery swapping stations.
An aluminum air battery is not commercially produced, mainly due to the high production cost of the anode, As well as issues with corrosion of the aluminium anode due to the carbon dioxide in air.Because of this, use of this battery is restricted to mainly military applications.

Huntington disease (HD): It is a progressive genetic disorder that affects the brain. It causes uncontrolled movements, impaired coordination of balance and movement, a decline in cognitive abilities, difficulty in concentrating and memory lapses, mood swings and personality changes. The cause of this disease is due to mutation in a gene called HTT. The main function of HTT genes is the production of a protein called Huntingtin. They provide the instruction for making the protein. The mutation of HTT gene gives faulty instructions and as a result the normal functioning of the brain is disrupted resulting in Huntington disease.
Recently, a team of scientists from National Centre for Cell Science (NCCS) in Pune led by Dr. Amitabha Majumdar unravelled that the pathogenic protein called the Huntingtin Protein causes decrease in overall protein production. They found that Huntingtin protein in a diseased person interfered with the protein production of the cells and how faulty information was sent to the brain. They are also the cause of the reduced level of protein production of a normal cell.

Geo-spatial sector in India: The Ministry of Science and Technology Monday recently released new guidelines for the Geo-spatial sector in India.
- The guidelines deregulate existing protocol and liberalises the sector to a more competitive field.
- The move is aimed at liberalizing geospatial services.
About Geospatial Data:
- Geospatial data is a data about objects on the surface of the earth, both natural and manmade.
- The location may be static in the short-term, like the location of a road, an earthquake event, malnutrition among children, or dynamic like a moving vehicle or pedestrian, the spread of an infectious disease.
- Geo-spatial data combines location information, attribute information (the characteristics of the object, event, or phenomena concerned), and often also temporal information or the time at which the location and attributes exist.
- Geo-spatial data usually involves information of public interest such as roads, localities, rail lines, water bodies, and public amenities.
- The past decade has seen an increase in the use of geo-spatial data in daily life with various apps such as food delivery apps like Zomato or Swiggy, e-commerce like Amazon or even weather apps.
The present policy on geo-spatial data is as follows:
- There are strict restrictions on the collection, storage, use, sale, dissemination of geo-spatial data and mapping under the current regime.
- The policy had not been renewed in decades and has been driven by internal as well as external security concerns.
- The sector so far is dominated by the Indian government as well as government-run agencies such as the Survey of India and private companies need to navigate a system of permissions from different departments of the government (depending on the kind of data to be created) as well as the defence and Home Ministries, to be able to collect, create or disseminate geo-spatial data.
- Initially conceptualized as a matter solely concerned with security, geo-spatial data collection was the prerogative of the defence forces and the government.
- GIS mapping was also rudimentary, with the government investing heavily in it after the Kargil war highlighted the dependence on foreign data and the need for indigenous sources of data.
Expected impact of new guidelines:
- By liberalizing the system, the government will ensure more players in the field, competitiveness of Indian companies in the global market, and more accurate data available to both the government to formulate plans and administer, but also for individual Indians.
- Startups and businesses can now also use this data in setting up their concerns, especially in the sector of e-commerce or geo-spatial based apps – which in turn will increase employment in these sectors.
- Indian companies will be able to develop indigenous apps, for example an Indian version of google maps.
SANDES: The National Informatics Centre (NIC), under the Ministry of Electronics and Information Technology, has launched an instant messaging platform called Sandes (Sandes in hindi means message).

- GIMS, like other instant messaging apps in the market, uses a valid mobile number or email id to register the user for the first time. It also offers features such as group making, broadcast message, message forwarding and emojis.
- Although there is no option to transfer the chat history between two platforms, the chats on GIMS can be backed up to a users’ email.
- The instant messaging app, called Sandes, has an interface similar to many other apps currently available in the market.
- The need to build a home-grown messaging platform was felt by the government to ensure secure communication between people as they worked from home, following the nationwide lockdown imposed to contain the spread of Covid-19.
- The app can be used by central and state government officials for intra-organisational and inter-organisational communication.
- The Sandes app is also a part of the government strategy to encourage the use of India-made software so as to build an ecosystem of indigenously developed software and products.
- Sandes was initially launched for Android users and mainly for government officers. Later, the service was also extended to iOS users and it is now available for the common public as well.
- In 2020, the ministry of home affairs had issued the advisory for the government employees to not use the platforms like Zoom for official communications because of security concerns.
- Before that, the Computer Emergency Response Team (Cert-In) had also issued an advisory against Zoom with respect to the safety and privacy concerns.

Space Hurricane: The scientists have discovered a “space hurricane” for the first time.
These hurricanes usually occur in the lower atmosphere of the Earth.
It was never observed in the upper atmosphere.
Earlier, the space hurricane was detected in August 2014 during a retrospective analysis which was led by the researchers at Shandong University of China.
Its findings were published in February 2021 in Nature Communications
The tech of scientists from USA, Norway, China and United Kingdom (UK) observed and produced the image of space hurricane using the Defense Meteorological Satellite Program (DMSP) satellites and a 3D magnetosphere modeling.
The hurricane swirled for eight hours over the North Pole in the upper atmosphere of Earth.
The hurricane that was detected over North Pole comprises of plasma with multiple spiral arms.
It was spinning in an anticlockwise direction.
The hurricane had the diameter of 1,000 kilometres while in altitude it reached from 110 kilometres to 860 kilometres.
It had the speed of up to 2,100 metres per second.
How will the study of space hurricane help the scientists?
The study of space hurricane will help the scientists to understand the important space weather effects like disturbances in high frequency radio communication, satellite drag, satellite navigation, errors in over-the-horizon radar location and communication systems.
What is space Hurricane?
A space hurricane is a huge, funnel-like, spiral geomagnetic storm that occurs above the polar Ionosphere of Earth, during extremely quiet conditions.
They are related to the aurora borealis phenomenon, as the electron precipitation from the storm's funnel produces gigantic, cyclone-shaped auroras.
The hurricane results into the stunning effect that is a huge, cyclone-shaped glowing green aurora can be observed below it.
Scientists believe that they occur in the polar regions of planets with magnetic fields.
Note: The astronomers have spotted hurricanes in space on Mars, Saturn and Jupiter.
Recently a large tanker appeared to be floating off the south coast of England in an optical illusion caused by a rare weather phenomenon called the superior mirage.
The extraordinary optical illusion was spotted by David Morris who was walking along the coast by Falmouth in Cornwall. He captured it on camera.
About Superior Mirage:
A mirage is a naturally occurring optical phenomenon in which light rays bend via refraction to produce a displaced image of distant objects or the sky. The word comes to English via the French mirer, from the Latin mirari, meaning "to look at, to wonder at".
In contrast to a hallucination, a mirage is a real optical phenomenon that can be captured on camera, since light rays are actually refracted to form the false image at the observer's location.
There are two types of mirages. They are inferior mirage (meaning lower) and superior mirage (meaning higher).
An inferior mirage occurs when you have a dense layer of cold air sitting on above of your line of sight, with a layer of less dense warmer air below your line of sight.
A superior mirage is seen above a flat surface of much lower temperature than the air above it. Superior mirages occur because of the weather condition known as a temperature inversion. Passing through the temperature inversion, the light rays are bent down, and so the image appears above the true object, hence the name superior. Superior mirages tend to be more stable than inferior mirages, as cold air has no tendency to move up and warm air has no tendency to move down.
The mirage is common in the Arctic Circle but can only very rarely be seen during the UK in winter.

Vaccine Maitri Initiative: It is an initiative launched by India to gift COVID-19 vaccines to neighbouring countries. Under this initiative, Sri Lanka and Bahrain have recently received the COVID-19 vaccines from India.
The Vaccine Maitri initiative was launched by India on January 20 to gift COVID-19 vaccines to neighbouring countries.
About the initiative:
Sri Lanka has received 5 lakh Covid-19 vaccines from India and consignment of vaccines has also been sent to Bahrain. The country will receive 10,800 vaccines as a part of the “Vaccine Maitri” initiative.
Before Sri Lanka and Bahrain, under this initiative, India has already delivered over 5 million doses to 7 countries in the neighbourhood.
The 7 countries are-
- Nepal (1 million vaccines)
- Bangladesh (2 million vaccines)
- The Maldives (100,000 vaccines)
- Bhutan (150,000 vaccines)
- Myanmar (1.5 million vaccines)
- Mauritius (100,000 vaccines)
- Seychelles (50,000 vaccines)
Commercial supplies of Covishield have also been sent to Morocco, Brazil, (2 million doses each), and Bangladesh (5 million doses).

Sunflower seed-sized chameleon: A team of scientists have recently found a sunflower seed-sized subspecies of a chameleon in Madagascar.
The scientists discovered two miniature lizards, one male and the other female. The male lizard dubbed Brookesia nana or nano-chameleon is merely 13.5 mm (0.53 inches) long. This is the smallest of all the roughly 11,500 known species of reptiles.
The researchers believe the male chameleon could be the tiniest reptile on the planet.
Einsteinium: A team of scientists at the Berkeley Lab recently reported some of the properties of element 99 in the periodic table called “Einsteinium”, named after Albert Einstein. This new study published in the journal Nature.
It is for the first time that the researchers have been able to characterise some of the properties of the element.
- It was discovered in 1952 in the debris of the first hydrogen bomb (the detonation of a thermonuclear device called “Ivy Mike” in the Pacific Ocean).
- Since its discovery, scientists have not been able to perform a lot of experiments with it because it is difficult to create and is highly radioactive. Therefore, very little is known about this element.
- The most common isotope of the element, einsteinium 253 has a half-life of 20 days.
- It has been noted that due to high radioactivity of the element, most of it has decayed since the beginning of the Earth.
- The element is invisible to the naked eye.
This is the reason that it cannot be found in nature and needs to be manufactured using very precise and intense processes.
The discovery of the Einsteinium:
When Ivy Mike was detonated on November 1, 1952, as part of a test at a remote island location called Elugelab on the Eniwetok Atoll in the South Pacific, it produced an explosion that was about 500 times more destructive than the explosion that occurred at Nagasaki.
This isotope was identified by Albert Ghiorso and coworkers at Berkeley, California, in debris taken from the first thermonuclear (hydrogen bomb) explosion, “Ivy Mike,” in the South Pacific (November 1952).
The element was named after the German-born physicist Albert Einstein.
BL Lacertae: Indian Astronomers recently detected one of the strongest optical flares in one of the oldest astronomical objects that is a super massive black hole or blazar called BL Lacertae.
The analysis of the flare from this blazar which is one of the oldest astronomical objects can help trace the mass of the black hole and the source of this emission. It can also provide a lead to probe into mysteries and trace events at different stages of evolution of the Universe.
What are Blazers?
Blazars are feeding super-massive black (SMBH) holes in the heart of distant galaxies. Like other forms of active galactic nuclei (AGN), blazars are the most luminous and energetic objects in the known universe.
They emit jets of charged particles traveling nearly at the speed of light and are one of the most luminous and energetic objects in the Universe.
BL Lacertae blazar:
BL Lacertae blazar is situated 10 million light-years away and is among the 50 most prominent blazars that can be observed with the help of a relatively small telescope.
This blazar was predicted to be experiencing flares with the help of the Whole Earth Blazar Telescope (WEBT), an international consortium of astronomers.
The Blazers receive a lot of attention from the astronomical community because of their complicated emission mechanism.

New Laser Technology: scientists in China have developed a new laser technology that is the 'space junk identification system' that can measure the space junk accurately. The researchers found a new way of using lasers to find space junk in a way similar to how bats use echolocation to track their prey. A unique set of algorithms for the laser ranging telescopes has improved the success rate of space debris detection. Laser ranging technique uses laser reflection from the objects to measure their distance. However, it has proved tricky to exactly pinpoint the swift, small specks of space Junk.
Space Junk: Earth is surrounded by space junk. This junk is formed from fragments of old satellites to exploded spacecraft. The clutter is a potential hazard for current and future spaceflight. Even small pieces of space junk can damage satellites and spacecraft as they whiz around Earth at up to about 17,500 mph. According to NASA uncountable debris is as small as a marble while millions are too small to be traced and some are just paint flecks from spacecraft. Even these very tiny particles have caused damage to the windows of the International Space Station.
Annular eclipse: An annular solar eclipse happens when the Moon covers the Sun's center, leaving the Sun's visible outer edges to form a “ring of fire” or annulus around the Moon. The ring of fire marks the maximum stage of an annular solar eclipse.
The annular solar eclipse occured in 26 December 2019. The eclipse was witnessed by thousands of people, including children and the aged, especially in northern districts of Kerala, while in some places, due to the clouds, it was not visible. The rare spectacle was first visible at Cheruvathur in Kasaragod, in the state followed by places in Kozhikode and Kannur.
Hundreds of devotees also reached the Ganga Ghat in Uttar Pradesh's Varanasi for a holy dip in the river and offered special prayers on the occasion of solar eclipse.

At present, India is paying a huge sum to Russia for the training of the first set of four astronaut candidates for the first Gaganyaan mission of 2022. Currently, HSP work is split across various centres like Vikram Sarabhai Space Centre in Thiruvananthapuram and the U.R. Rao Satellite Centre in Bengaluru.
Goldilocks Zone: It is a Zone that refers to the habitable zone around a star where the temperature is just right which is not too hot and not too cold for liquid water to exist on an planet. Scientists are always looking for planets in the Goldilocks Zone to hone in their search for Earth-like planets that could contain life.
For the first time, American space agency NASA's planet-hunter satellite Transiting Exoplanet Survey Satellite (TESS) has discovered an Earth-sized world within the habitable range of stars, which could allow the presence of liquid water. The newfound exoplanet named "TOI 700 d", is relatively close to Earth- only 100 light-years away. This new found exoplanet has become a good place for the scientists for their follow-up observations by other instruments.
TESS: It refers to Transiting Exoplanet Survey Satellite. It is NASA's planet hunter satellite. It was designed and launched specifically to find Earth-sized planets orbiting nearby stars. It was launched in April 2018. The satellite hunts for planets using the "transit method," looking for telltale dips in stellar brightness caused by orbiting worlds crossing stars' faces from the satellite's perspective.
As per the reports of astronomers, based on Kepler space mission data in November 2013, there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarfs in the Milky Way, 11 billion of which may be orbiting Sun-like stars. Kelper is NASA's space telescope.
Dwarf galaxies: A dwarf galaxy is a small galaxy composed of about 100 million up to several billion stars, a small number compared to the Milky Way's 200–400 billion stars.
Recently, astronomers have found massive blackholes near the Dwarf galaxies. These black holes are more than 100 times smaller than our own Milky Way and are apparently 400,000 times the mass of our Sun. The scientists by studying these black holes and the differences of the black holes in the larger and smaller galaxies are hoping to know about the evolution of Black holes from the earlier times.

The project aims at sending the astronauts to a lower orbit of the earth and the spacecraft will have a capsule with adequate supply of oxygen and other essential material and facilities for the astronauts.
Indian flight surgeons for the ambitious human space mission Gaganyaan will be trained by France as per the announcement made on 21st January 2020. France is to train Indian flight surgeons to enable them to monitor the health of astronauts selected for the human space mission Gaganyaan. The training will be given for two-week. It is a critical aspect of the Gaganyaan project that is aimed at sending three Indians to space by 2022. The flight surgeons are the Indian Air Force (IAF) doctors specializing in aviation medicines who will be responsible for the health of astronauts before, during and after the flight.
France not only has a well-established mechanism for space medicine but also has the MEDES space clinic, a subsidiary of CNES, where space surgeons undergo training. The 4 shortlisted astronauts all test pilots from the IAF are currently in Russia for an 11-month training programme.
Naegleria fowleri: It is a single celled amoeba. It is also called the brain-eating Amoeba. It is usually found in warm fresh water. However, the climatic changes have helped the amoeba to spread even during winter. It multiplies rapidly at forty-six degree Celsius.
The amoeba is usually found in rivers, lakes and causes infection called Primary Amoebic Meningoencephalitis. It is also called PAM and can be fatal
Recently, Naegleria fowleri has been in news because this amoeba is now rapidly spreading in the US. The news comes after a mysterious disease called Eluru was discovered in the districts of Andhra Pradesh.
PAM: It stands for Primary Amoebic Meningoencephalitis. The symptoms of PAM start to occur after 24 hours the amoeba entered the human body. The most common early symptom of the infection is head ache. The other symptoms are dizziness, stiff neck, vomiting, fever, nausea, seizures, etc.
The amoeba enters the human body through nose. It reaches the brain from the nose, where it feeds on the brain tissues. The unique fact about the amoeba is that it does not cause harm to the human body if it enters through the mouth. Thus, a person does not get infected by PAM by drinking contaminated water.
The Amoeba enters the human body from inadequately chlorinated swimming pools, contaminated tap water.
FAST: It refers to the Five Hundred Metre Aperture Spherical Telescope. FAST is the world's largest Radio Telescope. China recently announced that it is opening its Five Hundred Metre Aperture Spherical Telescope to international scientists.

It is a multi-disciplinary research centre with extensive infrastructure for advanced research and development covering the entire spectrum of nuclear science, engineering and related areas. Previously, the Government of India (GoI) created the Atomic Energy Establishment, AEET with Homi J. Bhabha (also known as the "Father of Indian Nuclear Programme"), as the founding director on 3 January 1954. After Homi Jehangir Bhabha's death in 1966, the centre was renamed as the Bhabha Atomic Research Centre on 22 January 1967.
Recently, BARC has developed Eye Cancer therapy in the form of the first indigenous Ruthenium 106 Plaque for treatment of Ocular Tumours.
The handling of plaque is very convenient for the Surgeon and it has been acknowledged to be at par with the international standards.
So far the BARC plaques made in India through the Department of Atomic Energy have been used for seven cases for Ocular Cancer.
Ocular tumors: Ocular tumors are tumors inside the eye. They are collections of cells that grow and multiply abnormally and form masses.
Ruthenium-106: Ruthenium-106 is a radioactive form of the rare heavy metal ruthenium, which is a "platinum group" metal similar to platinum.
It is produced from the fission or splitting of uranium-235, the type of uranium used in nuclear fission reactors, so it's found in spent nuclear fuel.
It is used in medicine for cancer radiation therapy, especially for skin and eye tumours. It is also used in radioisotope thermoelectric generators that power satellites.
Proxima Centauri: Proxima Centauri is a small, low-mass star located 4.2 light-years away from the Sun. It is considered a close distance in cosmic terms. This object was discovered in 1915 by Robert Innes and is the nearest-known star to the Sun. Its mass is about an eighth of the Sun’s, and it is too dim to be seen with the naked eye from Earth.
Recently, astronomers running the world’s largest initiative at the $100 million Breakthrough Listen project, started by the legendary physicist Stephen Hawking picked up an “intriguing” radio wave emission from the direction of Proxima Centauri, the closest star to our Sun.
The news has sparked renewed interest in Proxima Centauri, one of whose planets is believed to revolve in the star’s habitable zone, giving rise to the possibility that it could have, or does, sustain life.
QRNG: It refers to Quantum Random Number Generator. The DRDO Young Scientist Laboratory for Quantum Technologies (DYSL-QT), a DRDO facility based in Mumbai, has recently developed a QRNG. It has the ability to detect random quantum events and convert those into a stream of binary digits.
The facility has developed a fiber-optic branch path based QRNG.
The branch path based QRNG is based on the principle that if a single photon falls on a balanced beam splitter, it will take either of the beam-splitter output paths randomly
As the path chosen by photon is random, the randomness is translated to sequence of binary digits, also called bits.
QRNG system developed by the laboratory has passed the global randomness testing standards including NIST and Die-harder Statistical Test Suites at the speed of ~150 kbps after post-processing.
With this development India has entered the club of countries who have the technology to achieve the generation of random numbers based on the Quantum phenomenon.
Random Numbers: Random numbers play an important role in many fields, such as quantum communication, scientific simulation, cryptography (key generation, key packaging, identity verification, etc.), lotteries and fundamental physics experiments.
The generation of genuine randomness is generally considered impossible with classical means. Quantum mechanics has the inherent potential to provide real random numbers, so it has become the first choice for scientific applications that require randomness.
DYSL-QT: It is one of the five YSLs (Young Scientist Laboratories) of the DRDO which are working on five different technologies.
The other four facilities are:
- Cognitive Technologies (DYSL-CT) Chennai
- Artificial Intelligence (DYSL-AI) Bengaluru
- Asymmetric Technologies (DYSL-AT) Kolkata
- Smart Materials (DYSL-SM) Hyderabad.
These 5 facilities were dedicated to the nation by Prime Minister in January this year.

Vanadium: Arunachal Pradesh is likely to become India’s prime producer of vanadium. The Geological Survey of India (GSI) found promising concentrations of vanadium in the palaeo-proterozoic carbonaceous phyllite rocks in the Depo and Tamang areas of Papum Pare district in Arunachal Pradesh.
This was the first report of a primary deposit of vanadium in India, with an average grade of 0.76% V2O5 [vanadium pentoxide].
Vanadium mineralization in Arunachal Pradesh is geologically similar to the “stone coal” vanadium deposits of China hosted in carbonaceous shale. This high vanadium content is associated with graphite, with a fixed carbon content of up to 16%.
Indian scenario: India is a significant consumer of vanadium, but is not a primary producer of the strategic metal. According to data provided by the GSI, India consumed 4% of about 84,000 tonnes of vanadium produced across the globe in 2017.
Global scenario: The largest deposits of vanadium of the world are in China, followed by Russia and South Africa. China, which produces 57% of the world’s vanadium, consumed 44% of the metal in 2017.
Vanadium: Vanadium is a by-product obtained from the processing of Vanadiferous magnetite ores. In its pure form, Vanadium is soft, ductile and grey in colour. It is a chemical element with the symbol V and atomic number 23.
It is a hard, silvery-grey, malleable transition metal which is rarely found in nature. It is recovered as a by-product from the slag collected from the processing of vanadiferous magnetite ores (iron ore).
Vanadium is a high-value metal used in strengthening steel and titanium. The addition of the alloy improves the tensile strength of steel and of the reinforcing bars that are used for tunnels, buildings, and bridges. The alloys made of vanadium are durable in extreme environments and temperatures and are also corrosion-resistant.

590 MW of Solar Power Plant: France and Spain have recently signed an agreement to build 590 MW of solar power plant. It will be the largest solar power plant in Europe. The agreement was signed between Danone of France and Iberdrola of Spain.
The 364 million USD project is to be located in the western province of Caceres located in Spain.The solar power plant is to supply power to 375,000 people per year. It will avoid emission of 245,000 tonnes of Carbon Dioxide.
The project is to begin supplying power in 2022.
Spain: According to a BloombergNEF report, Spain, at present is Europe’s busiest subsidy-free photo-voltaic market, and leads the sector’s booming growth in the region. It commissioned 2.9 GW in 2020, four times the 729 MW of capacity added in 2019.
France: A target to installing 18 to 20 gigawatt of solar power by 2023 has been set by France. In 2016, France as well as India laid the foundation of International Solar Alliance (ISA). Though France is not a country located in the tropics, it joined hands with India in ISA mainly because the Solar Alliance was framed and announced at the UN Framework Convention on Climate Change, 2015 (the Paris agreement conference) hosted by France.
Aim of ISA: The main aim of International Solar Alliance (ISA) is to bring about major decrease in cost of solar energy. This is to be achieved by involving countries rich in solar energy, that is, those countries that are located between the Tropic of Cancer and Tropic of Capricorn.
Solar Energy of India: India has set a target of achieving 100 gigawatt of solar power by 2022 and has been increasing its solar power capacity. As of November 2020, the installed solar power of India was 36.9 GW. India has established 42 solar parks to make land available to the promoters of solar plants.
Signal: Signal is a cross-platform centralized encrypted messaging service developed by the Signal Technology Foundation and Signal Messenger LLC.
The non-profit Signal Foundation was launched in 2018 with initial funding of $50 million from Brian Acton. It uses the Internet to send one-to-one and group messages, which can include files, voice notes, images and videos. It can also be used to make one-to-one and group voice and video calls.
Signal uses standard cellular telephone numbers as identifiers and secures all communications to other Signal users with end-to-end encryption.
Anveshak: Researchers at the Indian Institute of Science (IISc.) have developed a software platform from which apps and algorithms can intelligently track and analyze video feeds from cameras spread across cities. Such analysis will not only prove to be useful for tracking missing persons or objects, but also useful for “smart city” initiatives such as automated traffic control.
Key Features of the Platform:
Yogesh Simmhan, Associate Professor in the Department of Computational and Data Sciences (CDS), and his team developed ‘Anveshak’, which not only runs these tracking models efficiently, but also plugs in advanced computer vision tools and intelligently adjust different parameters, such as a camera network’s search radius, in real time.
Anveshak can be used to track an object across a 1,000-camera network. A key feature of the platform is that it allows a tracking model or algorithm to focus only on feeds from certain cameras along an expected route, and tune out other feeds.
Anveshak will be useful not only for tracking missing persons or objects, but also for “smart city” initiatives such as automated traffic control.
