  • Species in news: Azhdarchid Pterosaurs

    Azhdarchid pterosaurs, the giant reptiles that flew in the skies nearly 65 million years ago, had necks longer than that of a giraffe (i.e. more than 6fts).

    What are pterosaurs?

    • Pterosaurs are reptiles that are close cousins of dinosaurs, the first animals after insects to evolve powered flight.
    • Some pterosaurs were as large as an F-16 fighter jet, while others were as small as a paper aeroplane.
    • Pterosaurs went extinct about 65-66 million years ago (end of the Cretaceous period) and while they did not leave any of their descendants behind.
    • One reason for this is that few pterosaurs lived in places where fossils tend to form, because of which their bones are preserved poorly.

    Revise the geological timescale from your NCERT textbook.

    Azhdarchid pterosaurs

    • They are one type of pterosaur and one of the distinguishing characteristics about them is how big they were, especially their long necks.
    • Some of these pterosaurs were the largest animals to have flown in the sky, with wingspans greater than 30 feet.
    • The name azhdarchid, as per a blog on Scientific American comes from Azhdarcho, a Central Asian form named by Russian ornithologist and palaeontologist in 1984.

    What have the researchers found?

    • Researchers involved in this study were curious about how the reptile’s long neck functioned and how it was able to support the pterosaur’s body, allowing them to capture and eat heavy prey animals.

  • [pib] National Internet Exchange of India (NIXI)

    The Ministry of Electronics & Information Technology (MeitY) has inaugurated three path-breaking initiatives for the National Internet Exchange of India (NIXI).

    What is NIXI?

    National Internet Exchange of India (NIXI) is a not-for-profit organization (section 8 of the Companies Act 2013) working since 2003 for spreading the internet infrastructure to the citizens of India through the following activities:

    1. Internet Exchanges through which the internet data is exchanged amongst ISP’s, Data Centers and CDNs.
    2. .IN Registry, managing and operation of .IN country-code domain and .à€­à€Ÿà€°à€€ IDN domain for India.
    3. IRINN, managing and operating Internet protocol (IPv4/IPv6).

    Which are the three new initiatives?

    (1) IPv6 Expert Panel (IP Guru) (https://nixi.in):

    • IP Guru is a group to extend support to all the Indian entities who are finding it technically challenging to migrate and adopt IPv6.
    • In addition to this, the IPv6 expert group will help in identifying & hiring an agency that will help end customer by providing necessary technical support to adopt IPv6.
    • This panel will guide all such Indian entities and help in increasing IPv6 adoption.

    Note: An Internet Protocol (IP) address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing.

    (2) NIXI Academy (https://training.nixi.in):

    • NIXI Academy is created to educate technical/non-technical people in India to learn and relearn technologies like IPv6 which are normally not taught in Educational Institutes.
    • NIXI academy comprises an IPv6 training portal which is developed with the help of various technical experts in order to provide mass training to the community.
    • The easy-to-use platform helps network operators and educators understand networking best practices, principles and techniques; manage Internet resources better; and use appropriate Internet technologies more effectively.

    (3) NIXI-IP-INDEX (https://ipv6.nixi.in):

    • NIXI has developed an IPv6 index portal for the Internet community.
    • NIXI-IP-INDEX portal will showcase the IPv6 adoption rate in India and across the world.
    • It can be used to compare the IPv6 Indian adoption rate with other economies in the world.
    • NIXI will populate this portal with web adoption in IPv6, IPv6 traffic etc. in the coming days.
    • This portal will motivate organisations to adopt IPv6, provide inputs for planning by technical organisations and research by academicians.

  • Indian Rhino Vision 2020

    The ambitious Indian Rhino Vision 2020 (IRV 2020) came to a close with the release of two rhinos — an adult male and a female — in Assam’s Manas National Park transported from Pobitora Wildlife Sanctuary about 185 km east.

    Try this PYQ:

    Q.Recently there was a proposal to translocate some of the lions from their natural habitat in Gujarat to which one of the following sites?

    (a) Corbett National Park

    (b) Kuno Palpur Wildlife Sanctuary

    (c) Mudumalai Wildlife Sanctuary

    (d) Sariska National Park

    What is IRV 2020?

    • In 2005, conservationists, alongside the Bodoland Territorial Council and the Government of Assam, came together to develop a long-term strategy to manage the species.
    • Their vision was ambitious; to build a 3,000-strong wild population of Greater one-horned rhinos by 2020, spread across seven sites in the state of Assam.
    • Thus the “Indian Rhino Vision 2020” (IRV2020) was born.

    Success of the IRV

    • Designed in 2005, the IRV2020 is believed to have achieved its target of attaining a population of 3,000 rhinos in Assam.
    • But the plan to spread the Rhinoceros unicornis across four protected areas beyond Kaziranga National Park, Orang National Park and Pobitora could not materialise.
    • Assam had at least five rhino-bearing areas till the 1980s.
    • Manas, in focus for the near-extinction of the pygmy hog, lost the World Heritage Site tag it received in 1985 along with Kaziranga from the UNESCO.
    • The translocated rhinos helped Manas National Park get back its World Heritage Site status in 2011.

  • [pib] Narrow-Line Seyfert 1 (NLS1) Galaxy

    Astronomers have discovered a new active galaxy identified as the farthest gamma-ray emitting galaxy that has so far been stumbled upon. This active galaxy called the Narrow-Line Seyfert 1 (NLS1) galaxy.

    Try this PYQ:

    Q.Recently, scientists observed the merger of giant ‘blackholes’ billions of light-years away from the Earth. What is the significance of this observation?

    (a) ‘Higgs boson particles’ were detected.

    (b) ‘Gravitational waves’ were detected.

    (c) Possibility of inter-galactic space travel through ‘wormhole’ was confirmed.

    (d) It enabled scientists to understand ‘singularity’.

    NLS1 Galaxy

    • Indian scientists have studied around 25,000 luminous Active galactic nuclei (AGN) from the Sloan Digital Sky Survey (SDSS).
    • They identified it as a gamma-ray emitting NLS1 galaxy, which is a rare entity in space.
    • It is about 31 billion light-years away, opens up avenues to explore more such gamma-ray emitting galaxies that wait to meet us.

    What makes it intriguing?

    • Ever since 1929, when Edwin Hubble discovered that the Universe is expanding, it has been known that most other galaxies are moving away from us.
    • Light from these galaxies is shifted to longer (and this means redder) wavelengths – in other words, it is red-shifted.
    • Scientists have been trying to trace such red-shifted galaxies to understand the early Universe.
    • Powerful relativistic jets, or sources of particles in the Universe travelling nearly at speed to light, are usually produced by AGN powered by large black holes and hosted in a giant elliptical galaxy.

    Why NLS1 is unique?

    • NLS1s are a unique class of AGN that are powered by the black hole of low mass and hosted in a spiral galaxy.
    • As of today, gamma-ray emission has been detected in about a dozen NLS1 galaxies, which are a separate class of AGN identified four decades ago.
    • All of them are at redshifts lesser than one, and no method was present to date to find NLS1 at redshifts larger than one.
    • This discovery opens up a new way to find gamma-ray emitting NLS1 galaxies in the early Universe.

  • [pib] E-SANTA: Electronic marketplace to connect Aqua farmers and buyers

    Union Commerce and Industry Ministry has inaugurated E-SANTA, an electronic marketplace providing a platform to connect aqua farmers and buyers.

    Note:

    Aquaculture also known as aquafarming is the farming of fish, crustaceans, mollusks, aquatic plants, algae, and other organisms. It involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish.

    Mariculture commonly known as marine farming refers to aquaculture practiced in marine environments and in underwater habitats, opposed to in freshwater.

    E-SANTA

    • The term e-SANTA was coined for the web portal, meaning Electronic Solution for Augmenting NaCSA farmers’ Trade-in Aquaculture.
    • It will enable the farmers to get a better price and the exporters to directly purchase quality products from the farmers enhancing traceability, a key factor in international trade.
    • National Centre for Sustainable Aquaculture (NaCSA) is an extension arm of Marine Products Export Development Authority (MPEDA), Ministry of Commerce & Industry.
    • It will raise income, lifestyle, self-reliance, quality levels, traceability, and provide new options for our aqua farmers.
    • The platform will change the traditional way of carrying out business from a word of mouth basis to become more formalized & legally binding.

    E-SANTA will RAISE the lives & income of farmers by:

    1. Reducing Risk
    2. Awareness of Products & Markets
    3. Increase in Income
    4. Shielding Against Wrong Practice
    5. Ease of Processes

    Its’ utility

    • E-SANTA is a Digital Bridge to end the market divide and will act as an alternative marketing tool between farmers & buyers by eliminating middlemen.
    • It will revolutionize traditional aqua farming by providing cashless, contactless and paperless electronic trade platform between farmers and exporters.
    • It can become a tool to advertise collectively the kind of products the buyers, fishermen & fish producing organisations are harvesting.

    How does it work?

    • E-SANTA is a completely paperless and end-to-end electronic trade platform between Farmers and exporters.
    • The farmers have the freedom to list their products and quote their price while the exporters have the freedom to list their requirements and also to choose the products based on their requirements.
    • This enables the farmers and buyers to have greater control over the trade and enables them to make informed decisions.
    • The platform provides a detailed specification of each product listing and it is backed by an end to end electronic payment system with NaCSA as an Escrow agent.
    • After crop listing and online negotiation, a deal is struck, advance payment is made and an estimated invoice is generated.

  • Monkeydactyl: the flying reptile with the ‘oldest opposable thumbs’

    Researchers have described a pterosaur species with opposable thumbs, which could likely be the earliest-known instance of the limb.

    Monkeydactyl

    • The pterosaur species were reptiles, close cousins of dinosaurs and the first animals after insects to evolve powered flight.
    • They evolved into various species; while some were as large as an F-16 fighter jet, others were as small as paper aeroplanes.
    • The new pterosaur fossil was discovered in the Tiaojishan Formation of Liaoning, China, and is thought to be 160 million years old.
    • It has now been described by an international team of researchers from China, Brazil, the UK, Denmark and Japan, and has been named Kunpengopterus antipollicatus, also dubbed “Monkeydactyl”.

    What has the team found?

    • “Antipollicatus” in ancient Greek means “opposite thumbs”, and it was attached to the name because the researchers’ findings could be the first discovery of a pterosaur with an opposed thumb.
    • Researchers suggested that K. antipollicatus could have used its hand for grasping, which is likely an adaptation for arboreal life.

    What makes it special?

    • Opposability of the thumb enables the species to “simultaneously flex, abduct and medially rotate the thumb” in a way that one is able to bring the tip of the thumb to touch the tips of the other fingers.
    • Along with humans, some ancient monkeys and apes also had opposable thumbs. Humans, however, have a relatively long and distally placed thumb, and larger thumb muscles.
    • This means that humans’ tip-to-tip precision grip when holding smaller objects is superior to non-human primates.
    • This is the reason that humans are able to hold a pen, unscrew an earring stopper, or put a thread through a needle hole.
    • The grasping hands of primates developed as a result of their life in the trees — an opposable thumb made it easier for the common ancestor of all primates to cling on to tree branches.

    Try this PYQ:

    Q.Some species of plants are insectivorous. Why?

    (a) Their growth in shady and dark places does not allow them to undertake sufficient photosynthesis and thus they depend on insects for nutrition

    (b) They are adapted to grow in nitrogen deficient soils and thus depend on insects for sufficient nitrogenous nutrition

    (c) They cannot synthesize certain vitamins themselves and depend on the insects digested by them

    (d) They have remained in that particular stage of evolution as living fossils, a link between autotrophs and heterotrophs

  • An aggressive vaccination drive holds the key to economic revival

    The article highlights the challenges posed by the second wave of covid and how aggressive vaccination could help dealing with the issue.

    Severe second covid wave in India

    • India’s daily new cases have surged past 1,50,000, much above the first peak.
    • In India’s first wave, the increase from 50,000 to about 1,00,000 cases took about 50 days; in the second wave, it’s taken just 13.
    • To start with, the second wave was more concentrated, with Maharashtra accounting for 60 per cent of cases.
    • While the top five states still account for about 65 per cent of cases, the reproduction (R) factor in almost 10 states is estimated to be two or higher, creating risks for a wider and more rapid spread, if unaddressed.

    Lessons from the first wave

    • Policymakers, businesses and households have all learnt from the first wave and with the private sector better adapted to “live with the virus”.
    • Therefore, the economic costs should hopefully not be comparable to the first wave. Yet, they may not be trivial either.
    • The five states that account for 65 per cent of new cases also account for almost 36 per cent of GDP.
    • As virus cases have grown and restrictions have been imposed, retail and recreational mobility across these five states, is down 10 per cent since mid-March.
    • Labour market surveys have also begun to show discernable impacts on both participation and unemployment rates.

    Implications of unequal recovery for developing countries

    • The IMF projects India’s FY22 growth at 12.5 per cent, this would still leave India about 8-9 per cent below the level of output that was projected pre-pandemic for the end of 2021-22.
    • The challenge for emerging markets is that, given the quantum of fiscal and monetary space expended in combating the first wave, space to respond to subsequent waves will be constrained.
    •  Owing to the fiscal support and pace of vaccinations the US will be the only large economy, apart from China, to surpass its pre-pandemic path.
    • This, resulted in increased US yields, tightened global financial conditions, induced dollar strength and triggered
    • All this makes it harder for emerging economies to respond expansively to domestic shocks.
    • In effect, the heterogeneity of the recovery across developed and emerging markets is imposing policy constraints on the latter which, ironically, will simply compound the economic divergence.

    Challenges for India

    • India’s fiscal space to respond to a second wave appears constrained due to the following two factors:
    • 1) In India’s case, consolidated public debt will approach 90 per cent of GDP.
    • 2) The consolidated public sector borrowing requirements are budgeted above 11 per cent of GDP in FY22.
    • The dependence on budgeted asset sales has only increased, both as a hedge to tax revenues that could be impacted from a second wave, and as a means of protecting expenditures.
    • It will be equally crucial to leaving enough space for higher MGNREGA demand and other safety nets on account of a second wave, even while protecting capital expenditures — which generate large multiplier effects on the economy.
    • Similarly, monetary policy is already very accommodative, and with core inflation sticky and elevated, global deflationary pressures entrenched, there are natural limits to the degree of more monetary accommodation.

    Aggressive vaccination is the key

    • Israel, the UK and the US have all demonstrated how aggressive vaccinations can bend the COVID-curve.
    • Therefore, the Indian government’s decision to approve a third vaccine and fast-track emergency approval for foreign-produced vaccines is unambiguously positive.
    • On the demand side, of an estimated 100-110 million population of seniors (60-plus) in India, only about 40 million have taken the vaccine over the last six weeks, suggesting a reluctance to get vaccinated.
    • But, in fact, it’s crucial to ensure the vulnerable — those whose probability of hospitalisation is the highest — are fully vaccinated to reduce pressure on the health infrastructure.

    Consider the question “What are the challenges posed to the developing countries by heterogeneity of recovery across the developed and developing countries?

    Conclusion

    Vaccinations should be construed as simultaneously delivering both a positive demand and supply shock (for the economy), and a negative demand shock (for health infrastructure), thereby providing the best chance to decisively break the trade-offs between lives and livelihoods that bedevilled emerging markets all of last year.

  • Why the Personal Data Protection Bill matters

    The existing data protection framework based on IT Act 2000 falls short on several counts. The Personal Data Protection Bill seeks to deal with the shortcoming in it. The article explains how the two differs.

    Need for new data protection regime

    • The need for a more robust data protection legislation came to the fore in 2017 post the Supreme Court’s landmark judgment in Justice K.S. Puttaswamy (Retd) v. Union of India.
    • In the judgment, the Court called for a data protection law that can effectively protect users’ privacy over their personal data.
    • Consequently, the Committee of Experts was formed under the Chairmanship of Justice (Retd) B.N. Srikrishna to suggest a draft data protection law.
    • The Personal Data Protection Bill, 2019, in its current form, is a revised version of the draft legislative document proposed by the Committee.

    Issues with the existing data protection framework

    • The Information Technology Act, 2000 governs how different entities collect and process users’ personal data in India.
    • However, entities could override the protections in the regime by taking users’ consent to processing personal data under broad terms and conditions.
    • This is problematic given that users might not understand the terms and conditions or the implications of giving consent.
    •  Further, the frameworks emphasise data security but do not place enough emphasis on data privacy.
    • As a result, entities could use the data for purposes different to those that the user consented to.
    •  The data protection provisions under the IT Act also do not apply to government agencies.
    • Finally, the regime seems to have become antiquated and inadequate in addressing risks emerging from new developments in data processing technology.

    How the new regime under Data Protection Bill 2019 is different

    • First, the Bill seeks to apply the data protection regime to both government and private entities across all sectors.
    • Second, the Bill seeks to emphasise data security and data privacy.
    • While entities will have to maintain security safeguards to protect personal data, they will also have to fulfill a set of data protection obligations and transparency and accountability measures.
    • Third, the Bill seeks to give users a set of rights over their personal data and means to exercise those rights.
    • Fourth, the Bill seeks to create an independent and powerful regulator known as the Data Protection Authority (DPA).
    • The DPA will monitor and regulate data processing activities to ensure their compliance with the regime.

    Concerns

    • Under clause 35, the Central government can exempt any government agency from complying with the Bill.
    • Similarly, users could find it difficult to enforce various user protection safeguards (such as rights and remedies) in the Bill.
    • For instance, the Bill threatens legal consequences for users who withdraw their consent for a data processing activity.
    • Additional concerns also emerge for the DPA as an independent effective regulator that can uphold users’ interests.

    Consider the question “What are the issues with the present framework in India for data and privacy protection? How the Personal Data Protection Bill seeks to address these issues?”

    Conclusion

    The Joint Parliamentary Committee that is scrutinising the Bill is expected to submit its final report in the Monsoon Session of Parliament in 2021 Taking this time to make some changes in the Bill targeted towards addressing various concerns in it could make a stronger and more effective data protection regime.

  • Shaphari Scheme

    Commerce Ministry wants to build confidence in quality, antibiotic-free shrimp products from India for the global market.

    Shaphari Scheme

    • The Marine Products Exports Development Authority (MPEDA) has developed a certification scheme for aquaculture products called ‘Shaphari’, a Sanksrit word that means the superior quality of fishery products suitable for human consumption.
    • The Shaphari scheme is based on the United Nations’ Food and Agriculture Organization’s technical guidelines on aquaculture certification.
    • It will have two components — certifying hatcheries for the quality of their seeds and, separately, approving shrimp farms that adopt the requisite good practices.
    • The certification of hatcheries will help farmers easily identify good quality seed producers.
    • Those who successfully clear multiple audits of their operations shall be granted a certificate for a period of two years.
    • The entire certification process will be online to minimize human errors and ensure higher credibility and transparency.

    Bolstering confidence in India’s Shrimp production

    • To bolster confidence in India’s frozen shrimp produce, the country’s biggest seafood export item, the Centre has kicked off a new scheme called ‘Shaphari’ to certify hatcheries and farms that adopt good aquaculture practices.
    • Frozen shrimp is India’s largest exported seafood item.
    • But a combination of factors had hurt export volumes in recent months, including container shortages and incidents of seafood consignments being rejected because of food safety concerns.
    • Some recent consignments sourced from Indian shrimp farms being rejected due to the presence of antibiotic residue and this is a matter of concern for exporters.
    • The National Residue Control Programme for food safety issues in farm produce and pre-harvest testing system is already in place.
    • But this certification was proposed as a market-based tool for hatcheries to adopt good aquaculture practices and help produce quality antibiotic-free shrimp products to assure global consumers.

    Frozen shrimp export potential

    • Frozen shrimp is India’s largest exported seafood item. It constituted 50.58% in quantity and 73.2% in terms of total U.S. dollar earnings from the sector during 2019-20.
    • India exported frozen shrimp worth almost $5 billion in 2019-20, with the U.S. and China its the biggest buyers.
    • Andhra Pradesh, West Bengal, Odisha, Gujarat and Tamil Nadu are India’s major shrimp producing States, and around 95% of the cultured shrimp produce is exported.

  • Indus and Ganges river dolphins are two different species

    Detailed analysis of South Asian river dolphins has revealed that the Indus and Ganges River dolphins are not one, but two separate species.

    About Gangetic Dolphin

    • The Gangetic river system is home to a vast variety of aquatic life, including the Gangetic dolphin (Platanista gangetica).
    • It is one of five species of river dolphin found around the world.
    • It is found mainly in the Indian subcontinent, particularly in Ganga-Brahmaputra-Meghna and Karnaphuli-Sangu river systems.
    • An adult dolphin could weigh between 70 kg and 90 kg. The breeding season of the Gangetic dolphin extends from January to June.
    • They feed on several species of fishes, invertebrates etc.

    Indus Dolphin is the divergent specie

    • Currently, they are classified as two subspecies under Platanista gangetica. The study estimates that Indus and Ganges river dolphins may have diverged around 550,000 years ago.
    • The international team studied body growth, skull morphology, tooth counts, colouration and genetic makeup and published the findings last month in Marine Mammal Science.

    Conservation status

    • The Indus and Ganges River dolphins are both classified as ‘Endangered’ species by the International Union for Conservation of Nature (IUCN).
    • It is the national aquatic animal and had been granted non-human personhood status by the government in 2017.
    • It is also protected under Schedule I of the Wildlife Protection Act (1972).
    • Vikramshila Gangetic Dolphin Sanctuary (VGDS) in Bihar is India’s only sanctuary for the Gangetic dolphin.
    • It has been categorised as endangered on the Red List of Threatened Species by the IUCN
    • Physical barriers such as dams and barrages created across the river, the declining river flows reduced the gene flow to a great extent making the species vulnerable.
