  • Life deep beneath Antarctica’s ice shelves

    Researchers have accidentally discovered living under the ice shelves of the Antarctic — in extremely cold and harsh conditions.

    Life beneath the Antarctic

    • Scientists have discovered sessile sponges — a pore bearing multicellular organism and other alien species — attached to the sides of rock beneath the ice sheets.
    • The unidentified species are estimated to be related to sponges, ascidians (sea squirts), hydroids, barnacles, cnidarian or polychaete. All of these look like bristle worms.
    • Scientists are yet to discover how these organisms access food.
    • They would use Environment Deoxyribonucleic acid (e-DNA) technology in future to identify the organisms.

    Organisms discovered

    Sponges

    • Sponges are the members of the phylum Porifera.
    • They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells.

    Ascidians

    • Ascidians, or sea squirts, are invertebrate chordates that belong to the earliest branch in the chordate phylum.
    • Ascidians are found all over the world, usually in shallow water with salinities over 2.5%.

    Hydroids

    • Hydroids are a life stage for most animals of the class Hydrozoa, small predators related to jellyfish.
    • Some hydroids such as the freshwater Hydra are solitary, with the polyp attached directly to the substrate.

    Barnacles 

    • Barnacles are a highly specialized group of crustaceans.
    • A barnacle is a type of arthropod related to crabs and lobsters.

    Cnidarians

    • Cnidarians, also called coelenterate, any member of the phylum Cnidaria (Coelenterata), a group made up of more than 9,000 living species.
    • Mostly marine animals, the cnidarians include the corals, hydras, jellyfish, Portuguese men-of-war, sea anemones, sea pens, sea whips, and sea fans.

    Now take this chance to revise your biology basics on various phyla. It will be beneficial for state PSC exams. UPSC has also begun puzzling us on core biology questions.

    Defying old theories

    • The discovery has left many of them baffled for it contradicts earlier theories of non-survival of life in such extreme conditions.
    • Until now, scientists believed that sea life decreased with an increase in the depth of the Antarctic ice floor.

  • NASA’s Perseverance rover makes historic Mars landing

    NASA’s rover Perseverance, the most advanced astrobiology laboratory ever sent to another world has landed safely on the floor of Jezero Crater on Mars.

    Last week, separate probes launched by the UAE (Hope Mission) and China (Tianwen-1) reached Martian orbit. NASA has three Mars satellites still in orbit, along with two from the European Space Agency.

    Perseverance Rover

    • The Perseverance rover weighs less than 2,300 pounds and is managed by NASA’s Jet Propulsion Lab.
    • It is a part of the mission named ‘Mars 2020’.
    • The rover’s mission will be to search for signs of past microbial life. It will also collect samples of Martian rocks and dust, according to the release.
    • All of NASA’s previous Mars rovers — including the Sojourner (1997), Spirit and Opportunity (2004) and Curiosity (exploring Mars since 2012) — were named in this way.

    Objectives of the mission

    • Looking for habitability: identify past environments capable of supporting microbial life.
    • Seeking bio-signatures: seek signs of possible past microbial life in those habitable environments, particularly in special rocks known to preserve signs over time.
    • Caching samples: collect core rock and regolith (“soil”) samples and store them on the Martian surface.
    • Preparing for humans: test oxygen production from the Martian atmosphere.

    Major components

    (a) Looking for underground water

    • Perseverance will carry the Radar Imager for Mars’ Subsurface Experiment (RIMFAX).
    • The instrument will look for subsurface water on Mars – which, if found, will greatly help the case for a human mission or the cause of a human settlement on Mars.

    (b) Testing a helicopter

    • The Mars Helicopter is a small drone. It is a technology demonstration experiment: to test whether the helicopter can fly in the sparse atmosphere on Mars.
    • The low density of the Martian atmosphere makes the odds of actually flying a helicopter or an aircraft on Mars very low.

    (c) Producing oxygen on Mars

    • Perseverance will have an instrument – MOXIE, or Mars Oxygen In-Situ Resource Utilization Experiment – that will use 300 watts of power to produce about 10 grams of oxygen using atmospheric carbon dioxide.
    • Should this experiment be successful, MOXIE can be scaled up by a factor of 100 to provide the two very critical needs of humans: oxygen for breathing, and rocket fuel for the trip back to Earth.

  • Govt liberalized Geospatial Data Policy

    In sweeping changes to the country’s mapping policy, the government has announced liberalisation of norms governing the acquisition and production of geospatial data.

    Q.What do you mean by Geo-Spatial Data? What are its economic and strategic significance?

    What is the news?

    • The Ministry of Science and Technology has released new guidelines for the Geo-spatial sector in India.
    • It deregulated the existing protocol and liberalizes the sector to a more competitive field.

    What is a Geo-Spatial Data?

    • Geospatial data is data about objects, events, or phenomena that have a location on the surface of the earth.
    • 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.
    • Geospatial data combines location information, attribute information, 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 geospatial data in daily life with various apps such as food delivery apps like Swiggy or Zomato, e-commerce like Amazon or even weather apps.

    What is the present policy on geospatial data?

    • 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.
    • Private companies need to navigate a system of permissions from different departments of the government as well as the defence and Home Ministries, to be able to collect, create or disseminate geospatial data.

    Why has the government deregulated geospatial data?

    • This system of acquiring licenses or permission, and the red tape involved, can take months, delaying projects, especially those that are in mission mode – for both Indian companies as well as government agencies.
    • The deregulation eliminates the requirement of permissions as well as scrutiny, even for security concerns.
    • Indian companies now can self-attest, conforming to government guidelines without actually having to be monitored by a government agency- these guidelines, therefore, place a great deal of trust in Indian entities.
    • There is also a huge lack of data in the country which impedes planning for infrastructure, development and businesses which are data-based.
    • The mapping of the entire country that too with high accuracy, by the Indian government alone could take decades.
    • The government, therefore, felt an urgent need to incentivise the geospatial sector for Indian companies and increased investment from private players in the sector.
    • Large amounts of geospatial data are also available on global platforms, which makes the regulation of data that is freely available in other countries, untenable.

    What next?

    • While for decades, geospatial data has been a priority for strategic reasons and for internal and external security concerns.
    • This priority has seen a shift in the past 15 years – geospatial data has now become imperative for the government in planning for infrastructure, development, social development as well as the economy.
    • More and more sectors such as agriculture, environment protection, power, water, transportation, communication, health (tracking of diseases, patients, hospitals etc) are relying heavily on this data.
    • There has also been a global push for open access to geospatial as it affects the lives of ordinary citizens.

    Expected impacts

    • By liberalizing the system, the government will ensure more players in the field, the 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 geospatial 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.
    • There is also likely to be an increase in public-private partnerships with the opening of this sector with data collection companies working with the Indian government on various sectoral projects.
    • The government also expects an increase in investment in the geospatial sector by companies, and also an increase in export of data to foreign companies and countries, which in turn will boost the economy.

  • ISRO collaborates to build alternative to Google Maps

    The ISRO has joined hands with MapmyIndia to combine their geospatial expertise and build holistic solutions by leveraging their geoportals.

    Note various geo-spatial solutions of ISRO mentioned in the newscard.

    What is the Project?

    • It combines the power of MapmyIndia’s digital maps and technologies with ISRO’s catalogue of satellite imagery and earth observation data.
    • Indian users would not be dependent on foreign organisations for maps, navigation and geospatial services, and leverage made-in-India solutions instead.

    Various components

    The collaboration will enable them to jointly identify and build holistic geospatial solutions utilising the ISRO’s earth observation datasets such as-

    • IRNSS (Indian Regional Navigation Satellite System) called NavIC (Navigation with Indian Constellation, is India’s own navigation system, developed by ISRO.
    • Bhuvan is the national geo-portal developed and hosted by ISRO comprising geospatial data, services and tools for analysis.
    • VEDAS (Visualization of Earth observation Data and Archival System) is an online geo-processing platform using an optical, microwave, thermal and hyperspectral EO data covering applications particularly meant for academia, research and problem solving, according to ISRO.
    • MOSDAC (Meteorological and Oceanographic Satellite Data Archival Centre)is a data repository for all the meteorological missions of ISRO and deals with weather-related information, oceanography and tropical water cycles.

    About MapmyIndia

    • MapmyIndia is an Indian technology company that builds digital map data, telematics services, location-based SaaS (Software as a service) and GIS AI services.
    • The company was founded in 1992 and is headquartered at New Delhi with regional offices in Mumbai and Bengaluru and smaller offices across India.
    • Its map covers all 7.5 lakh villages, 7500+ cities at street and building-level, connected by all 63 lakh kilometres of road network pan India and within cities, in total providing maps for an unparalleled 3+ crore places across India.

  • Mechanophotonics: Manipulating light through crystals

    Crystals are normally rigid, stiff structures, but researchers from the University of Hyderabad have shown how crystals can be sliced and even bent using atomic force microscopy. They have named this technique as “mechanophotonics”.

    The newscard discusses an out of the box technology which if brought to reality in practical use, can create immense disruptions in the technology market.

    Manipulating light through crystals

    • Manipulating them with precision and control comes in very useful in the field of nanophotonics, a qualitative, emerging field.
    • The aim is to go beyond electronics and build-up circuits driven entirely by photons (light).

    If the technique can be successfully developed, this can achieve an unprecedented level of miniaturisation and pave the way to all-optical-technology such as pliable, wearable devices operated by light entirely.

    What Indian researchers have achieved?

    : Bending light path

    • Light, when left to itself moves along straight paths, so it is crucial to develop materials and technology that can cause its path to bend along what is required in the circuits.
    • This is like using fibre optics, but at the nanoscale level using organic crystals.
    • The Hyderabad group has demonstrated how such crystals can be lifted, bent moved, transferred and sliced using atomic force microscopy.

    : How?

    • Researchers add a crucial piece to the jigsaw puzzle of building an “organic photonic integrated circuit” or OPIC.
    • Generally, millimetre- to centimetre-long crystals were bent using hand-held tweezers.
    • This method lacks precision and control. Also, the crystals used were larger than what was required for miniaturisation.
    • The atomic force microscopy (AFM) cantilever tip could be used to lift a crystal, as crystals tend to stick to the tip due to tip–crystal attractive forces.
    • Thus they demonstrated the real waveguiding character of the crystal lifted with a cantilever tip.

    In 2014, for the first time, the group led by Rajadurai Chandrasekar of the Functional Molecular Nano/Micro Solids Laboratory in University of Hyderabad demonstrated that tiny crystals could be lifted and moved with precision and control using atomic force microscopy.

    What is Atomic Force Microscopy (AFM)?

    • AFMs are a type of electron microscope used for the observation at an atomic level.
    • It is commonly used in nanotechnology.
    • The AFM works by employing an ultra-fine needle attached to a beam.
    • The tip of the needle runs over the ridges and valleys in the material being imaged, “feeling” the surface.

  • Novel Open Reading Frames (NORF)

    A team from the University of Cambridge set out to find whether new genes emerge in the genome of living organisms and if they do, how they do so. They have now catalogued 1,94,000 novel regions.

    Genes/Genomes/DNA/RNA is all-time favourite of UPSC. You can easily find 1-2 questions every year since 2017 in Prelims.

    Novel genomic regions

    • The ‘novel’ genomic regions cannot be defined by our current ‘definition’ of a gene.
    • Hence, researchers call these novel regions – novel Open Reading Frames or as nORFs.
    • Researchers found that the mutations in nORFs do have physiological consequences and a majority of mutations that are often annotated as benign have to be re-interpreted.

    What novel did the researchers find?

    • nORF regions were uniquely present in the cancer tissues and not present in the control tissue.
    • They found that some nORF disruptions strongly correlated with the survival of patients.
    • nORFs proteins can form structures, can undergo biochemical regulation like known proteins and be targeted by drugs in case they are disrupted in diseases.
    • The researchers also identified these nORFs in Plasmodium falciparum, the parasite which causes the deadliest form of malaria.

    Connected to disease

    • The research found that these regions are also broadly involved in diseases.
    • The nORFs were seen as dysregulated in 22 cancer types.
    • Dysregulated is a term which means that they could either be mutated, upregulated, or downregulated, or they could be uniquely present.

  • [pib] FASTag declared mandatory

    Ministry of Road Transport & Highways has decided that all lanes in the fee plazas on National Highways shall be declared as “FASTag lane of the fee plaza”.

    Fastag went unnoticed this year. The RFID technology deployed in this holds an intuition for its relevance in CS prelims and many forthcoming exams.

    What is ‘FASTag’?

    • FASTags are stickers that are affixed to the windscreen of vehicles and use Radio Frequency Identification (RFID) technology to enable digital, contactless payment of tolls without having to stop at toll gates.
    • The tags are linked to bank accounts and other payment methods.
    • As a car crosses a toll plaza, the amount is automatically deducted, and a notification is sent to the registered mobile phone number.

    How does it work?

    • The device employs Radio Frequency Identification (RFID) technology for payments directly from the prepaid or savings account linked to it.
    • It is affixed on the windscreen, so the vehicle can drive through plazas without stopping.
    • RFID technology is similar to that used in transport access-control systems, like Metro smart card.
    • If the tag is linked to a prepaid account like a wallet or a debit/credit card, then owners need to recharge/top up the tag.
    • If it is linked to a savings account, then money will get deducted automatically after the balance goes below a pre-defined threshold.
    • Once a vehicle crosses the toll, the owner will get an SMS alert on the deduction. In that, it is like a prepaid e-wallet.

  • Dickinsonia fossil discovered in Bhimbetka

    Researchers have found the first-ever fossil in India of a Dickinsonia —the Earth’s ‘oldest animal’, dating back 570 million years — on the roof of what’s called the ‘Auditorium Cave’ at Bhimbetka.

    Dickinsonia

    • Dickinsonia is an extinct genus of basal animal that lived during the late Ediacaran period in what is now Australia, Russia and Ukraine.
    • The individual Dickinsonia typically resembles a bilaterally symmetrical ribbed oval.
    • Its affinities are presently unknown; its mode of growth is consistent with a stem-group bilaterian affinity, though some have suggested that it belongs to the fungi or even an “extinct kingdom”.
    • The discovery of cholesterol molecules in fossils of Dickinsonia lends support to the idea that Dickinsonia was an animal.

    What are the new findings?

    Like the awe-inspiring rock shelters themselves, this fossil was discovered by chance.

    • Dickinsonia fossils have shown that they could exceed four feet in length but the one found in Bhimbetka is 17 inches long.
    • Eleven feet above the ground, almost blending with the rock and easily mistaken by laymen for prehistoric rock art, they found imprints of the Dickinsonia.
    • It is believed to be one of the key links between the early, simple organisms and the explosion of life in the Cambrian Period, about 541 million years ago.

    Cambrian Explosion and Dickinsonia

    • The ‘Cambrian Explosion’ is the term given to the period of time in history when complex animals and other macroscopic organisms such as molluscs, worms, arthropods and sponges began to dominate the fossil record.
    • Researchers from Australian found the Dickinsonia fossil since its tissue contained molecules of cholesterol a type of fat that is the hallmark of animal life.

    Do you know?

    Cosmogenic nuclide dating is deployed to determine time of earliest human culture. India’s oldest stone-age tools, up to 1.5 million years old, are at a prehistoric site near Chennai.

    About Bhimbetka

    • The Bhimbetka rock shelters are an archaeological site in central India that spans the prehistoric Paleolithic and Mesolithic periods, as well as the historic period.
    • It exhibits the earliest traces of human life in India and evidence of Stone Age starting at the site in Acheulian times.
    • It is located in the Raisen District in Madhya Pradesh about 45 kilometres (28 mi) south-east of Bhopal.
    • It is a UNESCO World Heritage Site that consists of seven hills and over 750 rock shelters distributed over 10 km (6.2 mi).
    • At least some of the shelters were inhabited more than 100,000 years ago.
    • Some of the Bhimbetka rock shelters feature prehistoric cave paintings and the earliest are about 10,000 years old (c. 8,000 BCE), corresponding to the Indian Mesolithic.
    • These cave paintings show themes such as animals, early evidence of dance and hunting.
    • The Bhimbetka rock shelters were found by V S Wakankar 64 years ago. Since then, thousands of researchers have visited the site, but this rare fossil went undetected.

  • Einsteinium: the mysterious element named after Albert Einstein

    The University of California has reported some of the properties of element 99 in the periodic table called “Einsteinium”, named after Albert Einstein.

    Try this PYQ:

    Q.The known forces of nature can be divided into four classes, viz, gravity, electromagnetism, weak nuclear force and strong nuclear force.

    With reference to them, which one of the following statements is not correct? (CSP 2012)

    (a) Gravity is the strongest of the four

    (b) Electromagnetism act only on particles with an electric charge

    (c) Weak nuclear force causes radioactivity

    (d) Strong nuclear force holds protons and neutrons inside the nuclear of an atom.

    Einsteinium

    • 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.
    • With this new study published in the journal Nature last week, for the first time researchers have been able to characterize some of the properties of the element.

    The discovery of the element

    • 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.
    • The blast produced an explosion that was about 500 times more destructive than the explosion that occurred at Nagasaki.
    • Subsequently, the fallout material from this explosion was sent to Berkeley in California for analysis which identified over 200 atoms of the new element.

    Properties of the element

    • Einsteinium has a half-life of 20 days.
    • Because of its high radioactivity and short half-life of all einsteinium isotopes, even if the element was present on Earth during its formation, it has most certainly decayed.
    • This is the reason that it cannot be found in nature and needs to be manufactured using very precise and intense processes.
    • Therefore, so far, the element has been produced in very small quantities and its usage is limited except for the purposes of scientific research.
    • The element is also not visible to the naked eye and after it was discovered, it took over nine years to manufacture enough of it so that it could be seen with the naked eye.
