  • Stellar Mid-life Crisis: What ails the middle-aged Sun?

    Stars like our Sun can go through a mid-life crisis, according to new research carried out by scientists from IISER Kolkata.

    Stellar Middle Age

    • At about 4.6 billion years of age, the sun is middle-aged, that is, it will continue to live for roughly the same period.
    • There are accurate methods for estimating the age of the Sun, such as by using radioactive dating of very old meteorites that have fallen on the Earth.
    • However, for more distant stars which are similar in mass and age to the Sun, such methods are not possible.
    • One of the methods used is called gyrochronology.
    • There is a relationship between rotation rate and age, that is the rotation rate of a star slows down with age.

    How does it occur?

    • When the stellar wind escapes from the star, it carries away with it a part of the angular momentum of the star, which results in its slowing down.
    • The stellar wind has two drivers: one is the high temperature of the outer atmosphere of stars – the corona – which results in an outward expansion and hence plasma winds that emanate out.
    • The other is the magnetic field.
    • The magnetic field actually heats the corona and so when magnetic activity is strong the winds are strong and since wind carries away the internal (rotational) angular momentum of the star, it slows down its rotation.
    • This is called magnetic braking.
    • As the star ages, due to this mechanism, its rotation slows down and this relationship is used in gyrochronology to estimate the age of the star.

    Impact

    • This can lead to dramatic changes in their activity and rotation rates.
    • The study also provides an explanation for the breakdown of the long-established relation between rotation rate and age in middle-aged sunlike stars.
    • However, there is a breakdown of the gyrochronology relationship, because, after midlife, a star’s rate of spin does not slow down with age as fast as it was slowing down earlier.
    • Another intriguing fact is that the Sun’s activity level has been observed to be much lower than other stars of similar age.

  • [pib] Digital Payment Solution: e-RUPI

    The Prime Minister has launched e-RUPI, a person and purpose-specific digital payment solution.

    What is e-RUPI?

    • e-RUPI is a cashless and contactless instrument for digital payment.
    • It is a QR code or SMS string-based e-Voucher, which is delivered to the mobile of the beneficiaries.
    • The users of this seamless one-time payment mechanism will be able to redeem the voucher without a card, digital payments app, or internet banking access, at the service provider.
    • It has been developed by the National Payments Corporation of India on its UPI platform, in collaboration with the Department of Financial Services, Ministry of Health & Family Welfare, and National Health Authority.

    How does it work?

    • e-RUPI connects the sponsors of the services with the beneficiaries and service providers in a digital manner without any physical interface.
    • It also ensures that the payment to the service provider is made only after the transaction is completed.
    • Being pre-paid in nature, it assures timely payment to the service provider without the involvement of any intermediary.

    Benefits offered

    • It is expected to be a revolutionary initiative in the direction of ensuring a leak-proof delivery of welfare services.
    • Even the private sector can leverage these digital vouchers as part of their employee welfare and corporate social responsibility programs.

    Answer this PYQ in the comment box:

    Q.Which of the following is the most likely consequence of implementing the ‘Unified Payments Interface (UPI)’?

    (a) Mobile wallets will not be necessary for online payments.

    (b) Digital currency will totally replace physical currency in about two decades.

    (c) FDI inflows will drastically increase.

    (d) Direct transfer of subsidies to poor people will become very effective

  • First group insolvency proceeding points to larger weakness in IBC

    Context

    National Company Law Appellate Tribunal (NCLAT) stayed the approval granted by the Mumbai bench of the National Company Law Tribunal (NCLT) to the resolution plan for the Videocon Group.

    Concerns with resolution plan

    • Resolution plan submitted by Twinstar Technologies, provided for payment of Rs 2,962 crore — a mere 4.15 per cent of Videocon’s total admitted debt of Rs 64,838 crore.
    • Payment of debt not in fair and equitable manner:  Under the IBC (Section 30(2)(b)), the resolution plan must provide for payment of debts amongst creditors in a “fair and equitable” manner.
    • However, in the plan submitted by Twinstar, unsecured assenting financial creditors and operational creditors are getting a paltry 0.62 per cent and 0.72 per cent of their admitted dues.
    • Even the secured assenting and dissenting financial creditors had to settle for only 4.9 per cent and 4.56 per cent of their respective dues.
    • Confidentiality obligation concerns: Twinstar’s bid of Rs 2,962 crore is close to the liquidation value of the Videocon Group estimated at Rs 2,568 crore, thereby raising legitimate suspicion and concern over the confidentiality of the resolution process.
    • The I&B Regulations, 2016 state that the resolution professional must maintain the confidentiality of the fair market value and liquidation value of the corporate debtor and can only disclose the same to the CoC members after the resolutions plan have been submitted.
    • Time delay: Status-quo ante has been restored until the next date of hearing by which time more than three years would have passed since the Videocon group was admitted into insolvency proceedings.
    • This is way beyond the statutory timeline of 330 days.

    Confidentiality rules need to be revised

    • The CoC members must, on receipt of the information, issue an undertaking of confidentiality.
    • But no such obligation falls on the resolution professional.
    • Further, Section 29(2) of the code provides that the resolution professional must disclose all “relevant information” to the resolution applicant and it is for the resolution applicant to ensure compliance with confidentiality obligations.
    • Again, there is no such duty imposed on the resolution professional.
    • Even under Section 25 of the code, titled “Duties of resolution professional”, the specific duty to maintain confidentiality of sensitive information is absent.
    • Clearly, the current regime does not have much deterrence value so as to ensure solemn adherence to confidentiality.

    Conclusion

    Videocon was one of the first test cases to examine the prospects of insolvency jurisprudence in India and the first one, for group insolvency proceedings.  However, almost four years and a 95 per cent haircut later, the call for an immediate course correction couldn’t be louder.

    Back2Basics: Operational creditor and financial creditors

    • When a corporate defaulter is brought under the resolution process (Corporate Insolvency Resolution Process or CIRP), there can be two types of creditors to whom the corporate should give back money –
    • (1) the entities who gave loans or funds to the corporate.
    • (2) the entities from whom the corporate bought inputs and other services.
    • The financial creditors are basically entities (lenders like banks) that have provided funds to the corporate.
    • Their relationship with the entity is a pure financial contract, such as a loan or debt security.
    • On the other hand, business and other entities that have provided inputs and other materials and services and to whom the defaulted corporate owes a debt are called as operational creditors.
    • Both have claims on the defaulted corporate or the defaulted corporate owe payments to both these categories.
    • Rights for these categories under the resolution process are also different.
    • The IBC gives a clear preference to the claims of the financial creditors over the operational creditors through several procedures.

    Haircut

    • A haircut is the difference between the loan amount and the actual value of the asset used as collateral.
    • It reflects the lender’s perception of the risk of fall in the value of assets.
    • But in the context of loan recoveries, it is the difference between the actual dues from a borrower and the amount he settles with the bank.

  • [pib] Near-Surface Shear Layer (NSSL) of Sun

    Indian astronomers have found a theoretical explanation for the existence of the Near-Surface Shear Layer (NSSL) of the Sun for the first time.

    What is a Near-Surface Shear Layer?

    • It was long known the Sun’s equator spins faster than the poles.
    • However, a peek into the internal rotation of the Sun using sound waves revealed the existence of an intriguing layer where the rotation profile of the Sun changes sharply.
    • The layer is called as a near-surface shear layer (NSSL), and it exists very close to the solar surface, where there is an outward decrease in angular velocity.

    What have researchers found?

    • They have used an equation called the thermal wind balance equation to explain how the slight difference in temperature between solar poles and equator, called thermal wind term.
    • It is balanced by the centrifugal force appearing due to solar differential rotation.
    • They have noted that if this condition is true near the solar surface, it can explain the existence of NSSL, which is inferred in helioseismology (technique of using sound waves to peek inside the Sun) based observation.

    Why study NSSL?

    • Understanding NSSL is crucial for the study of several solar phenomena like sunspot formation, solar cycle, and it will also help in understanding such phenomena in other stars.

  • [pib] What are PRIDE Guidelines?

    The Union Ministry for Science & Technology has released “Biotech-PRIDE (Promotion of Research and Innovation through Data Exchange) Guidelines” developed by the Department of Biotechnology (DBT).

    Biotech-PRIDE

    • These guidelines aim at providing a well-defined framework and guiding principle to facilitate and enable sharing and exchange of biological knowledge, information and data.
    • They will facilitate this and enable the exchange of information to promote research and innovation in different research groups across the country.
    • They will be implemented through the Indian Biological Data Centre (IBDC) at Regional Centre for Biotechnology supported by the Department of Biotechnology.

    Creating a national repository: Bio-Grid

    • Other existing datasets/ data centres will be bridged to this IBDC which will be called Bio-Grid.
    • This Bio-Grid will be a National Repository for biological knowledge, information and data.
    • It will be responsible for enabling its exchange, developing measures for safety, standards and quality for datasets and establishing detailed modalities for accessing data.

     Why need such guidelines?

    • India ranks number 4 amongst the top 20 countries contributing biological databases.
    • The Government invests a large number of public funds for biosciences to gain deep insights into intricate biological mechanisms and other processes and for translation.

  • The epoch of cyberweapons

    Context

    The controversy over the use of Pegasus spyware for snooping highlights the threats posed by cyber-weapons.

    The emergence of the cyber weapons epoch

    • Cyberattacks on institutions such as banks and on critical infrastructure have proliferated to an alarming extent, signaling the emergence of the cyber weapon epoch.
    • Privacy has been eroded and the Internet has become a powerful weapon in the hands of those seeking to exploit its various facets.
    • Fifth dimension of warfare: Cyber is often touted as the fifth dimension of warfare — in addition to land, sea, air and space.

    The domain of everyday life

    • Cyber, as the domain of military and national security, also co-exists with cyber as a domain of everyday life.
    • The war is no longer out there.
    • It is now directly inside one’s drawing-room, with cyberweapons becoming the weapon of choice.
    • Israelis today dominate the cyber domain along with the Chinese, Russians, Koreans and, of course, the Americans.
    • The linkage between sabotage and intrusive surveillance is but a short step.

    Cyberattacks during the past decades

    •  Beginning with the 2007 devastating cyberattack on Estonia’s critical infrastructure, this was followed by the Stuxnet worm attack a few years later on Iran’s nuclear facility.
    • The Shamoon virus attack on Saudi Aramco occurred in 2012.
    • In 2016, a cyberattack occurred on Ukraine’s State power grid; in 2017 there was a Ransomware attack (NotPetya) which affected machines in as many as 64 countries.
    • United Kingdom’s National Health Service fell prey to the Wannacry attack the same year.
    • The series of attacks happened this year on Ireland’s Health Care System and in the United States such as ‘SolarWinds’, the cyber attack on Colonial Pipeline and JBS, etc.

    What are the threats posed by cyberattacks?

    • Cyberweapons carry untold capacity to distort systems and structures — civilian or military.
    • Cyberweapons also interfere with democratic processes, aggravate domestic divisions and, above all, unleash forces over which established institutions or even governments have little control.
    • As more and more devices are connected to networks, the cyber threat is only bound to intensify, both in the short and the medium term.
    • What is especially terrifying is that instruments of everyday use can be infected or infiltrated without any direct involvement of the target.
    • The possibilities for misuse are immense and involve far graver consequences to an individual, an establishment, or the nation.
    • It is not difficult to envisage that from wholesale espionage, this would become something far more sinister such as sabotage.

    Way forward

    • Deeper understanding:  Dealing with ‘zero day’ vulnerabilities require far more thought and introspection than merely creating special firewalls or special phones that are ‘detached’ from the Internet.
    • Recognising the mindset: What is needed is a deeper understanding of not only cyber technologies, but also recognising the mindsets of those who employ spyware of the Pegasus variety, and those at the helm of companies such as the NSO.
    • Short-term remedies are unlikely to achieve desired results.
    • No use of AI: Artificial Intelligence (AI) is often seen as a kind of panacea for many of the current problems and ills, but all advances in technology tend to be a double-edged sword.
    • If truth be told, AI could in turn make all information warfare — including cyber related — almost impossible to detect, deflect or prevent, at least at the current stage of development of AI tools.

    Conclusion

    All this suggests that security in the era of ever-expanding cyberweapons could become an ever-receding horizon.

    Back2Basics: Zero-day vulnerability

    • The term “zero-day” refers to a newly discovered software vulnerability.
    • Because the developer has just learned of the flaw, it also means an official patch or update to fix the issue hasn’t been released.
    • So, “zero-day” refers to the fact that the developers have “zero days” to fix the problem that has just been exposed — and perhaps already exploited by hackers.

  • Why cloudbursts could become more frequent?

    Recently, cloudbursts have been reported from several places in J&K, Ladakh, Uttarakhand and Himachal Pradesh. A

    What is a Cloudburst?

    • Cloudbursts are short-duration, intense rainfall events over a small area.
    • According to the IMD, it is a weather phenomenon with unexpected precipitation exceeding 100mm/h over a geographical region of approximately 20-30 square km.

    What causes Cloudburst?

    • A study published last year studied the meteorological factors behind the cloudburst over the Kedarnath region.
    • They analyzed atmospheric pressure, temperature, rainfall, cloud water content, cloud fraction, cloud particle radius, cloud mixing ratio, total cloud cover, wind speed, wind direction, and relative humidity during the cloudburst, before as well as after the cloudburst.
    • The results showed that during the cloudburst, the relative humidity and cloud cover was at the maximum level with low temperature and slow winds.
    • It is expected that because of this situation a high amount of clouds may get condensed at a very rapid rate and result in a cloudburst.

    Impact of climate change

    • Several studies have shown that climate change will increase the frequency and intensity of cloudbursts in many cities across the globe.
    • As temperatures increase the atmosphere can hold more and more moisture and this moisture comes down as a short very intense rainfall for a short duration.
    • This results in flash floods in the mountainous areas and urban floods in the cities.
    • Also, there is evidence suggesting that globally short duration rainfall extremes are going to become more intense and frequent.

  • [pib] 14 Indian Tiger Reserves get Global CA/TS recognition

    The Environment Ministry has released the names of the 14 tiger reserves that had received the accreditation of the Global Conservation Assured|Tiger Standards (CA|TS), an accreditation tool agreed upon by tiger range countries.

    Conservation Assured | Tiger Standards (CA|TS)

    • CA|TS has been agreed upon as an accreditation tool by the global coalition of Tiger Range Countries (TRCs) and has been developed by tiger and protected area experts.
    • Officially launched in 2013, it sets minimum standards for effective management of target species and encourages the assessment of these standards in relevant conservation areas.
    • CA|TS is a set of criteria that allows tiger sites to check if their management will lead to successful tiger conservation.
    • The Global Tiger Forum (GTF), an international NGO working on tiger conservation, and World Wildlife Fund India are the two implementing partners of the National Tiger Conservation Authority for CATS assessment in India.

    Which are the 14 reserves?

    The 14 tiger reserves which have been accredited are:

    • Manas, Kaziranga and Orang in Assam,
    • Satpura, Kanha and Panna in Madhya Pradesh,
    • Pench in Maharashtra,
    • Valmiki Tiger Reserve in Bihar,
    • Dudhwa in Uttar Pradesh,
    • Sunderbans in West Bengal,
    • Parambikulam in Kerala,
    • Bandipur Tiger Reserve of Karnataka and
    • Mudumalai and Anamalai Tiger Reserve in Tamil Nadu

    Significance

    • CATS accreditation is a global recognition of good tiger governance.
    • This recognition means a lot in the context of adaptation to climate change, sustainability of ecosystem services, and safeguarding disruption of zoonotic cycles, through an umbrella species approach.
    • The aspects monitored for accreditation include the importance and status of a reserve, management, community participation, tourism, protection, habitat management, and tiger populations.

  • How to exit farming risk trap

    Context

    The farmers’ protest against farm laws brings into focus the factors afflicting agriculture in India.

    Issues of Indian agriculture

    • Some 50 years after the Green Revolution, an all-India agricultural landscape is characterized by relatively low productivity levels that co-exist with high levels of variation in crop yields across our farming districts.
    • Excessive control: Various government agencies have a say on all aspects of the farmer’s livelihood — the latest count includes 13 central and countless state ministries and agencies.
    • These agencies oversee rural property rights, land use, and land ceilings; commodity prices, input subsidies, and taxes, infrastructure, production, credit, marketing and procurement, public distribution, research, education, trade policy, etc.
    • Poor policies: The result has been a mix of arbitrary and conflicting policy interventions by both the central and state government agencies.
    • Poor provision of basic public goods: This, combined with poor and varying levels of provision of basic public goods, including irrigation explains the poor state of Indian agriculture.

    Risk-to-return in agriculture

    • The following figures indicate the median (typical) district-level yield (in tonnes-per-hectare) for four major crops — rice, wheat, maize, and cotton — along with the geographic variability of this yield (risk) across all reporting districts for each year from 1966 to 2018.
    • Combining these two values — median district yield and its geographic variability across all farming districts — provides us a measure of the all-India level of risk-to-return, in percentage terms.

    Lessons from risk-to-return profile

    • One, the large gap in rice and wheat yields that opened up between Punjab and Haryana and the farm districts in the rest of the country remains far from being closed.
    • Limited mobility of ideas: There is severe unevenness in the provision of common goods across districts — irrigation, roads, power, etc.
    • There is also the absence of well-functioning markets for agricultural land, crops, and inputs, the slow labour reform, and the poor quality of education.
    • These two factors have worked to reduce overall resource mobility within and across our farming districts.
    • Most importantly, they have limited the mobility of ideas and technology needed to increase productivity and reduce the variation of yield across districts.
    • Decentralization failed: As a result of lack of mobility, the real promise of a decentralized system — of experimentation, of learning from each other, and the adoption of best practices and policies — has failed to materialize.
    • Distortion due to subsidies: Various input subsidies and minimum price guarantee procurement schemes provided by the state have worked to worsen the overall levels of productivity and the risk in agriculture, generating adverse effects for all of us, through the degradation of our water resources, soil, health, and climate.
    • At the same time, these policies have tightened the trap our farm households find themselves in.
    • Thus, as is evident in the next chart, outside of rice and wheat, the risk-to-return levels are even higher in the case of maize and cotton, including for Punjab.
    • As a result, the farm households of Punjab and Haryana fear both, the loss of state support for rice and wheat and the higher risks implied by a switch to other crops.

    Way forward

    • Minimize risk: The guiding principle for three farm laws must be to create conditions that allow farm households to maximize their income while minimizing the overall level of risk in Indian agriculture.
    • Freedom of choice: Farmers must be made free to determine the best mix of resources, land, inputs, technology, and organizational forms for their farms.
    • More freedom: Farmers, just as entrepreneurs in the non-farm sector, must be allowed to enter and exit agriculture, on their own terms and contract with whomever they wish.
    • Allow entry of corporates: Entry of the large or small private corporates in the Indian agricultural stream will help the Indian farmer, along with the rest of us, move to a low-risk, high-return path of progress.

    Conclusion

    The more we delay the needed reforms, the more difficult it will prove to be for all of us to extract ourselves out of these risk-laden currents of agriculture.
