    What are Fast Radio Bursts (FRB)?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Fast Radio Burst (FRB)

    Mains level: Not Much

    In a paper published in Nature, astronomers have reported a fast radio burst (FRB) whose characteristics are different from almost all other FRBs previously detected.

    Such news makes us think about alien and extraterrestrial life at the first. Do not get carried away with such thoughts. Its simply a space based phenomena.

    Fast Radio Burst (FRB)

    • FRBs are super intense, millisecond-long bursts of radio waves produced by unidentified sources in the distant cosmos.
    • They were first discovered in 2007 when scientists combed through archival pulsar data.
    • Pulsars refer to spherical, compact objects in the universe, which are about the size of a large city but contain more mass than the sun.
    • They often look like flickering stars but are not stars.

    Why in news?

    • The new study in Nature describes FRB 20190520B, first discovered in 2019.
    • What makes it different is that unlike many other FRBs, it emits frequent, repeating bursts of radio waves.
    • And between bursts, it constantly emits weaker radio waves.
    • FRB 190520B is co-located with a compact, persistent radio source and associated with a dwarf host galaxy of high specific star formation.

    Rhino reintroduction a hit in Assam Reserves

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Indian Rhino

    Mains level: Not Much

    The one-horned rhinos of western Assam’s Manas National Park, bordering Bhutan, are expected to have high life expectancy and significant growth in population, the 14th Assam rhino estimation census has revealed.

    Indian Rhino

    • The Indian rhinoceros also called the greater one-horned rhinoceros and great Indian rhinoceros is a rhinoceros native to the Indian subcontinent.
    • It is listed as Vulnerable on the IUCN Red List and Schedule I animal in the Wildlife Protection Act, 1972.
    • It once ranged across the entire northern part of the Indian Subcontinent, along the Indus, Ganges and Brahmaputra River basins, from Pakistan to the Indian-Myanmar border.
    • Poaching for rhinoceros horn became the single most important reason for the decline of the Indian rhino.

    Why in news?

    • The 14th Rhino Population Estimation / Census in Kaziranga National Park counted at least 2613 rhinos including calves, a jump of exactly 200 rhinos since the last census conducted in 2018.
    • Then at least 2413 Rhinos were counted in the national park.

    Threats to Rhinos

    • Ground rhino horn is used in traditional Chinese medicine to cure a range of ailments, from cancer to hangovers, and also as an aphrodisiac.
    • In Vietnam, possessing a rhino horn is considered a status symbol.
    • Due to demand in these countries, poaching pressure on rhinos is ever persistent against which one cannot let the guard down.

    Various protection moves

    • A rhino reintroduction programme under the Indian Rhino Vision 2020 was started in 2006.
    • This entailed the translocation of rhinos from Kaziranga National Park and Pobitora Wildlife Sanctuary besides orphans hand-reared at the Centre for Wildlife Rehabilitation and Conservation at Kaziranga.

  • Indian Navy Updates

    Next-Generation Corvettes for Indian Navy

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Corvettes

    Mains level: Indian navy modernization

    The Defence Acquisition Council (DAC) has given the Acceptance of Necessity (AoN) for the procurement of next-generation Corvettes for the Indian Navy at an approximate cost of Rs 36,000 crore.

    What is a Corvette?

    • A Corvette is the smallest class of naval ships and it falls below the warship class of a frigate.
    • These are highly agile ships and are categorised as missile boats, anti-submarine ships, coastal patrol crafts and fast attack naval vessels.
    • The word corvette itself is derived from French and Dutch origin.
    • During World War II, the term Corvette was used to describe vessels which had anti-submarine roles assigned to them.
    • Modern Corvettes can go up to 2,000 tons in displacement which helps in keeping them agile.

    What kind of Corvettes does the Indian Navy possess?

    • The Indian Navy at present has the Kamorta Class Corvettes, which are also known as Project 28.
    • These ships have an anti-submarine role and are manufactured at Garden Reach Shipbuilders and Engineers in Kolkata.
    • The four Kamorta Class Corvettes that the Indian Navy possesses are named INS Kamorta, INS Kadmatt, INS Kiltan and INS Kavaratti.
    • The first of these was commissioned in 2014 and the last one in 2020.

    What new capabilities will the new generation Corvettes have?

    • The next-generation Corvettes will be manufactured for various roles like surveillance missions, escort operations, deterrence, surface action group operations, search and attack and coastal defence.
    • It is worth noting that these roles will be in addition to the anti-submarine roles being already performed by the existing Corvettes in the Navy.
    • Corvettes will be constructed based on new in-house design of the Indian Navy using latest technology of ship buildings.
    • They would contribute to further the government’s initiative of Security and Growth for all in the region (SAGAR).

    Dostarlimab: The New Wonder Cancer Drug

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Dostarlimab

    Mains level: NA

    A trial on 18 colorectal cancer patients in the US found that cancer could be treated without chemotherapy or surgery. The world is sitting up and taking note of Dostarlimab, which has been called a wonder drug.

    What is Dostarlimab?

    • Dostarlimab is an experimental drug. It contains laboratory-produced molecules.
    • It acts as substitute antibodies. It is sold under the brand name Jemperli.
    • It was approved for medical use in the United States and the European Union in 2021.
    • Its side-effects include vomiting, joint pain, itching, rash, fever etc.

    What are the findings?

    • The trial showed that immunotherapy alone – without any chemotherapy, radiotherapy, or surgery that have been staples of cancer treatment.
    • It could completely cure the patients with a particular kind of rectal cancer called ‘mismatch repair deficient’ cancer”.
    • All 12 patients had completed the treatment and were followed for six to 25 months after.
    • No cases of progression or recurrence had been reported during the follow-up.
    • The response too was rapid, with symptoms resolving in 81% of the patients within nine weeks of starting the therapy.

    Is Dostarlimab actually very effective?

    • Dostarlimab is not a new drug but a combination of drugs that are already approved for use in immunotherapy.
    • There is a possibility that Dostarlimab may improve the outcome and survival rate in rectal cancer patients but to say it as a magic drug for cancer is completely going overboard.

    How does this drug cure?

    • PD1 is a protein that regulates immune function and can sometimes keep T cells from killing cancer cells.
    • The therapy in the trial used PD1 blockades, allowing T cells to kill cancer cells.
    • ‘Mismatch repair deficient’ cancer is most common among colorectal, gastrointestinal, and endometrial cancers.
    • Patients suffering from this condition lack the genes to correct typos in the DNA that occur naturally while cells make copies.
    • Immunotherapy belongs to a category called PD1 blockades that are now recommended for the treatment of such cancers rather than chemotherapy or radiotherapy.

    Will Indian patients get access to the drug?

    • At present, Indian doctors seem to be generally wary of prescribing Dostarlimab for their patients.
    • Experts have termed as optimistic the findings of an ongoing trial—a group of rectal cancer patients showed no signs of a tumour after taking the drug for six months.
    • None of the participants reported any severe side-effects either.
    • Yet, doctors say they want to assess the duration of the response.

    What do we know about the clinical trial?

    • Cancer was treated in all the patients and could not be detected by physical examination, endoscopy, positron emission tomography, or magnetic resonance imaging.
    • Thus, there is a thought that cancer can be treated without chemotherapy or surgery.

    Is it too early to celebrate?

    • Cancer specialists said initial signals show how precision medicine is building the future but they need to test more patients from different areas and other types of cancers.
    • The combination of drugs was administered to a small number of patients and for a specific type of cancer.

    RBI plans to link Credit Cards with UPI

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Features of UPI

    Mains level: Not Much

    The RBI has proposed to allow the linking of credit cards with the Unified Payments Interface (UPI).

    Integrating Credit Cards to UPI

    • The integration will first begin with the indigenous RuPay credit cards.
    • Both the RuPay network and UPI are managed by the same organisation – the National Payments Corporation of India (NPCI).

    What is UPI?

    • UPI is an instant real-time payment system developed by National Payments Corporation of India (NPCI) facilitating inter-bank transactions.
    • The interface is regulated by the Reserve Bank of India and works by instantly transferring funds between two bank accounts on a mobile platform.

    Why such move?

    • The linkage of UPI and credit cards could possibly result in credit card usage zooming up in India given UPI’s widespread adoption.
    • The integration also opens up avenues to build credit on UPI through credit cards in India, where in the last few years, a number of startups like Slice, Uni, One etc. have emerged.
    • The move could also be a push to increase adoption by banking on UPI’s large user base.
    • So far, UPI could only be linked to debit cards and bank accounts.
    • This will provide additional convenience to the users and enhance the scope of digital payments.

    What could be the hurdles?

    • There are some regulatory areas that would have to be addressed before the linkage happens.
    • For instance, it is not clear how the Merchant Discount Rate (MDR) will be applied to UPI transactions done through credit cards.
    • UPI and RuPay attract zero-MDR, meaning that no charges are applied to these transactions, which is a key reason behind the prolific adoption of UPI both by users and merchants.
    • The norm has faced pushback from the payments industry.
    • It has argued that it limits the aggregators’ ability to invest in and maintain the financial infrastructure of the payment ecosystem that they have built.
    • Applicability of zero-MDR on UPI could also be a reason why other card networks such as Visa and Mastercard may not have been onboarded to UPI for credit cards yet.

    Note: MDR is a fee that a merchant is charged by their issuing bank for accepting payments from their customers via credit and debit cards.

    What is the big picture?

    • UPI has become the most inclusive mode of payment in India with over 26 crore unique users and five crore merchants on the platform.
    • The progress of UPI in recent years has been unparalleled.
    • Many other countries are engaged with us in adopting similar methods in their countries.
    • In May, UPI processed 5.95 billion transactions worth over Rs 10 trillion, a record high since its launch in 2016.
    • NPCI is looking to soon process a billion transactions a day.

     

    Try this PYQ from CSP 2017:

    Q.Which one of the following best describes the term “Merchant Discount Rate” sometimes seen in news?

     

    (a) The incentive given by a bank to a merchant for accepting payments through debit cards pertaining to that bank

    (b) The amount paid back by banks to their customers when they use debit cards for financial transactions for purchasing goods or services

    (c) The charge to a merchant by a bank for accepting payments from his customers through the bank’s debit cards

    (d) The incentive is given by the Government to merchants for promoting digital payments by their customers through Point of Sale (PoS) machines and debit cards

    [pib] Children in Street Situations (CiSS) Application

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: CiSS Application

    Mains level: Child rights issue

    The National Commission for the Protection of Child Rights (NCPCR) has launched a “CiSS application” under the Baal Swaraj portal to help in the rehabilitation process of Children in Street Situations (CiSS).

    CiSS Application

    • The CiSS application is used for receiving data of children in street situations from all the states and union territories, tracking their rescue and rehabilitation process.
    • The initiative is taken under the direction of the Supreme Court of India.
    • The program embodies Article 51 (A) of the Constitution of India, as it provides a platform to the public and organizations catering to the welfare of the children to report any child in need of assistance.
    • The platform serves to collect data and report to the District Child Protection Officer (DCPO) for them to take necessary action.
    • It also provides a platform for professionals and organizations to provide any help that they can to children in need.
    • Help can be provided in the form of open shelters, counselling services, medical services, sponsorships, de-addiction services, education services, legal/paralegal services, volunteering etc.

    Its working framework

    • It categorizes any child under ‘Children in Street Situation’ if the child is living on the streets alone, living on the streets during the day, or living on the streets with the family.
    • The root cause of this phenomenon is the migration of families from rural to urban areas in search of a better standard of living.

    How does it work?

    It follows six stages framework for the rehabilitation of children.

    1. Collection of the child’s details, which is accomplished through the portal.
    2. Social Investigating Report (SIR)e. investigating the child’s background. This is done under the supervision of the District Child Protection Unit (DCPU) by the District Child Protection Officer (DCPO) by conversing and counselling the child.
    3. Formulating an Individual Care Plan (ICP) for the child.
    4. Child Welfare Committee (CWC) based on the SIR submitted to the CWC.
    5. Allocating the schemes and benefits that the beneficiary can avail of.
    6. A checklist is made for the evaluation of the progress i.e. (Follow Ups).

  • Climate Change Impact on India and World – International Reports, Key Observations, etc.

    Environmental Performance Index (EPI), 2022

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Environmental Performance Index

    Mains level: Western anti-India lobby

    India has objected to a report, called the EPI, 2022, that places the country last (along with Nigeria) on a list of 180 countries on managing climate change, environmental health, and ecosystem vitality.

    Environmental Performance Index

    • The report is prepared by researchers at the Yale and Columbia universities.
    • It provides a data-driven summary of the state of sustainability around the world.
    • Using 40 performance indicators across 11 issue categories, the EPI ranks 180 countries on climate change performance, environmental health, and ecosystem vitality.
    • These indicators provide a gauge at a national scale of how close countries are to established environmental policy targets.
    • The EPI offers a scorecard that highlights leaders and laggards in environmental performance and provides practical guidance for countries that aspire to move toward a sustainable future.

    Why the report is inherently biased?

    • The US placed itself at the 20th spot of the 22 wealthy democracies in the global west and 43rd overall.
    • The relatively low ranking has put all blame on the rollback policies during the Trump administration.
    • It goes on to preach that developing countries do not have to sacrifice sustainability for economic security.

    Understanding SEBI Rules on Passive Funds

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Passive Funds

    Mains level: Not Much

    The Securities and Exchange Board of India (SEBI) recently issued a circular on passive funds covering matters related to transparency, liquidity and operational aspects of exchange-traded funds (ETFs) and index funds.

    What are Passive Funds?

    • A passive fund is an investment vehicle that tracks a market index, or a specific market segment, to determine what to invest in.
    • Unlike with an active fund, the fund manager does not decide what securities the fund takes on.
    • This normally makes passive funds cheaper to invest in than active funds, which require the fund manager to spend time researching and analysing opportunities to invest in.
    • Tracker funds, such as ETFs (exchange traded funds) and index funds fall under the banner of passive funds.

    What is a passive ELSS scheme?

    • Passive funds mimic an underlying index. By contrast active funds are actively managed by fund managers.
    • The SEBI has now introduced a passive equity-linked saving schemes (ELSS) category, which will give taxpayers another investment option to avail of tax benefits.
    • According to the circular, the passive ELSS scheme will be based on any index comprising equity shares from the top 250 companies in terms of market capitalization.
    • Beginning 1 July, a fund house will be able to either have an active ELSS scheme or a passive ELSS scheme, but not both.

    What are the norms for debt ETFs?

    • Passive debt funds are now divided into three categories:
    1. Corporate debt funds with exposure to corporate bonds
    2. G-Sec funds investing in government securities, and
    3. Hybrid funds where allocation is a combination of corporate bonds and government securities
    • Currently, debt funds in the passive category invest only in AAA-rated instruments.
    • The Sebi circular introduces norms for each debt fund category, including portfolio exposure limits to each sector, the issuer (based on rating) and group.
    • Application of these provisions should help mitigate concentration risk in debt ETFs/ index funds.

    What about tracking error?

    • As per Sebi’s circular, passive funds must disclose ‘tracking error’ and ‘tracking difference’ in their monthly fact sheets.
    • These metrics indicate how different the performance of the fund is compared to its underlying index—an effort to keep investors better informed.
    • The circular specifies limits for tracking error and tracking difference, which passive funds must follow.

    What is the mandate on disclosing NAVs?

    • Because of poor liquidity for ETFs in the secondary market in India, ETF prices could differ widely from the net asset value (NAV) of the fund.
    • The NAV of the fund represents the value of the underlying asset of the ETF.
    • The Sebi circular mandates disclosure of NAV (indicative) on a continuous basis throughout the day on the stock exchange.
    • While the practice is already in existence, Sebi rules institutionalize it.
    • Checking the NAV can help one avoid making a transaction at a significant premium or discount.

    Can one execute ETF transactions directly?

    • Investors can buy or sell units of ETFs only on stock exchanges.
    • But, large buy or sell transactions can also be directly placed with the fund house.
    • Sebi now says orders greater than ₹25 crore alone can be placed for redemption or subscription directly with the asset management company (AMC).

    Sant Kabir: the extraordinary poet-saint of the Bhakti Movement

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Kabir, Bhakti Movement

    Mains level: NA

    President Kovind inaugurated the Sant Kabir Academy and Research Centre Swadesh Darshan Yojana and paid tribute to the Bhakti saint, Kabir at Maghar, his resting place in Uttar Pradesh.

    Kabir and the Bhakti Movement

    • The Bhakti movement, which began in the 7th century in South India, had begun to spread across north India in the 14th and the 15th centuries.
    • The movement was characterized by popular poet-saints who sang devotional songs to God in vernacular languages.
    • Most of the preaching were meant for abolishing the Varna system and promoting Hindu-Muslim unity.
    • They emphasized an intense emotional attachment with God.

    Who was Sant Kabir?

    • One school within the Bhakti movement was the Nirguni tradition and Sant Kabir was a prominent member of it.
    • In this tradition, God was understood to be a universal and formless being.
    • Many of the saints of the Bhakti movement came from the ranks of the lower to middle artisanal classes.
    • Kabir was an alleged ‘low caste’ weaver (Julaha), Raidas was a leather worker and Dadu a cotton carder.
    • Their radical dissent against orthodoxy and rejection of caste made these poet-saints extremely popular among the masses and their ideology of egalitarianism spread across India.

    His life

    • He was born in Varanasi and lived between the years 1398 and 1448, or till the year 1518 according to popular belief.
    • He was from a community of ‘lower caste’ weavers of the Julaha caste, a group that had recently converted to Islam.
    • He learned the art of weaving, likely studied meditative and devotional practices under the guidance of a Hindu guru and grew to become an eminent teacher and poet-singer.
    • Kabir’s beliefs were deeply radical, and he was known for his intense and outspoken voice which he used to attack the dominant religions and entrenched caste systems of the time.
    • He composed his verses orally and is generally assumed to be illiterate.

    His literary works

    • Kabir’s compositions can be classified into three literary forms – dohas (short two liners), ramanas (rhymed 4 liners), sung compositions of varying length, known as padas (verses) and sabdas (words).
    • There are myriad legendary accounts on the other hand, for which there exists less of a factual historical basis.

    Kabir’s critique of religion and caste

    • Kabir is in modern times portrayed as a figure that synthesized Islam and Hinduism.
    • While he did borrow elements from different traditions, he very forcefully proclaimed his independence from them.
    • He did not only target the rituals and practices of both Hinduism and Islam, but also dismissed the sacred authority of their religious books, the Vedas and the Quran.
    • He even combined Allah and Ram in his poems.
    • He sought to eradicate caste distinctions and attempted to create an egalitarian society, by stressing the notion that a Bhakt (devotee) was neither a Brahmin nor an ‘untouchable’ but just a Bhakt.

    Kabir’s legacy

    • Kabir’s own humble origins and his radical message of egalitarianism fostered a community of his followers called the Kabir Panth.
    • A sect in northern and central India, many of their members are from the Dalit community.
    • All regard Kabir as their guru and treat the Bijak as their holy scripture.
    • The Bijak contains works attributed to Kabir and is argued by historians to have been written in the 17th century.
    • Several of Kabir’s verses and songs form a vital part of the Guru Granth Sahib.
