  • Species in news: Red Sea Turtles

    Turtle populations in the Red Sea could be turning overwhelmingly female because of a rise in sea temperatures caused due to anthropogenic climate change, a new study has showed.

    Try this PYQ:

    Q.Consider the following fauna of India:

    1. Gharial
    2. Leatherback turtle
    3. Swamp deer

    Which of the above is/are endangered?

    (a) 1 and 2 only

    (b) 3 only

    (c) 1, 2 and 3

    (d) None

    Red Sea Turtles

    • There are seven extant species worldwide, five of which can be found in the Red Sea: the green turtle, the hawksbill turtle, the loggerhead turtle, the olive ridley turtle and the leatherback turtle.
    • In order to maintain a 50:50 ratio of male and female in the population, a temperature of 29.2 degrees Celsius is pivotal.
    • Above this, hatchlings would be predominantly female.
    • The sand temperatures at four of the sites exceeded 29.2 degrees; leading the team to the conclusion that ‘feminization’ of the population could be already happening.

    Their significance

    • Marine turtles—as all top predators—have a prominent role in maintaining balanced and healthy ecosystems, in particular seagrass beds and coral reefs.
    • They also help in transporting nutrients towards naturally nutrient-poor ecosystems (the nesting beaches), and providing food and transportation for other marine species (e.g., barnacles and commensal crabs).
    • Marine turtles also play an important role in the economy of the tourism industry.

  • HL-2M Tokamak: The Artificial Sun of China

    China successfully powered up its “artificial sun” nuclear fusion reactor for the first time marking a great advance in the country’s nuclear power research capabilities.

    Scratch your school basics to answer 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.

    HL-2M Tokamak

    • The HL-2M Tokamak reactor is China’s largest and most advanced nuclear fusion experimental research device.
    • The mission is named Experimental Advanced Superconducting Tokamak (EAST).
    • Located in Sichuan province and completed late last year, the reactor is often called an “artificial sun” on account of the enormous heat and power it produces.
    • It uses a powerful magnetic field to fuse hot plasma and can reach temperatures of over 150 million degrees Celsius- approximately ten times hotter than the core of the sun.
    • Scientists hope that the device can potentially unlock a powerful clean energy source.

    Back2Basics: Nuclear Fusion

    • Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons).
    • Fusion is the process by which the sun and other stars generate light and heat. It is a nuclear process, where energy is produced by smashing together light atoms.
    • It is the opposite reaction of fission, where heavy elements like Uranium and Thorium are split apart.

    Nuclear Fusion Reaction

    • For a nuclear fusion reaction to occur, it is necessary to bring two nuclei so close that nuclear forces become active and glue the nuclei together.
    • Nuclear forces are small-distance forces and have to act against the electrostatic forces where positively charged nuclei repel each other.
    • This is the reason nuclear fusion reactions occur mostly in high density, high-temperature environment (millions of degree Celsius) which is practically very difficult to achieve under laboratory conditions.

  • Surveyor-2 Spacecraft

    NASA has confirmed that the Near-Earth Object called 2020 SO is the rocket booster that helped lift the space agency’s Surveyor spacecraft toward the Moon in 1966.

    Try this PYQ:

    Consider the following phenomena:

    1. Size of the sun at dusk
    2. Colour of the sun at dawn
    3. Moon being visible at dawn
    4. Twinkle of stars in the sky
    5. Polestar being visible in the sky

    Which of the above are optical illusions?

    (a) 1, 2 and 3

    (b) 3, 4 and 5

    (c) 1, 2 and 4

    (d) 2, 3 and 5

    What is Surveyor-2?

    • The Surveyor-2 spacecraft was supposed to make a soft landing on the Moon’s surface in September 1966, during which time one of the three thrusters failed to ignite.
    • As a result of this the spacecraft started spinning and crashed on the surface.
    • The aim of the mission was to reconnoiter the lunar surface ahead of the Apollo missions that led to the first lunar landing in 1969.
    • While the spacecraft crashed into the Moon’s surface, the rocket booster disappeared into an unknown orbit around the Sun.

    How was the object determined to be the rocket booster?

    • Astronomers track asteroids using telescope to determine if there are potentially hazardous asteroids that pose a threat to the planet.
    • Therefore, it is also important for them to be able to distinguish between natural and artificial objects that orbit around the Sun.
    • The rocket booster has come “somewhat close” to the Earth in the past few decades.
    • One approach to the Earth in late 1966 was so close that the object was thought to have originated from Earth.
    • In September, the NASA-funded telescope detected it.

  • Arecibo Radio Telescope

    A massive radio telescope at Puerto Rico’s Arecibo Observatory — one of the world’s largest — collapsed on after sustaining severe damage, following 57 years of astronomical discoveries.

    Try this PYQ:

    Which of the following is/are cited by the scientists as evidence/evidence for the continued expansion of the universe?

    1. Detection of microwaves in space
    2. Observation of redshirt phenomenon in space
    3. Movement of asteroids in space
    4. Occurrence of supernova explosions in space

    Codes:

    (a) 1 and 2 only

    (b) 2 only

    (c) 1, 3 and 4

    (d) None of the above can be cited as evidence.

    Arecibo Telescope

    • The Arecibo Observatory, also known as the National Astronomy and Ionosphere Center (NAIC), was an observatory in Arecibo, Puerto Rico owned by the US National Science Foundation (NSF).
    • It was the world’s largest single-aperture telescope for 53 years, surpassed in July 2016 by the Five-hundred-meter Aperture Spherical Telescope (FAST) in China.
    • The second-largest single-dish radio telescope in the world, it had withstood many hurricanes and earthquakes since it was first built in 1963.

    Its contributions

    • Being the most powerful radar, scientists employed Arecibo to observe planets, asteroids and the ionosphere.
    • It made several discoveries over the decades, including finding prebiotic molecules in distant galaxies, the first exoplanets, and the first millisecond pulsar.
    • In 1967, Arecibo was able to discover that the planet Mercury rotates in 59 days and not 88 days as had been originally thought.
    • In the following decades, it also served as a hub in the search for extraterrestrial life, and would look for radio signals from alien civilizations.
    • In 1993, scientists Russell Hulse and Joseph Taylor were awarded the Nobel Prize in Physics for their work on the observatory in monitoring a binary pulsar.
    • It provided a strict test of Einstein’s Theory of General Relativity and the first evidence for the existence of gravitational waves.

  • Australian Square Kilometre Array Pathfinder (ASKAP)

    A powerful new telescope ASKAP, in Australia has mapped vast areas of the universe in record-breaking time, revealing a million new galaxies and opening the way to new discoveries.

    Note all important telescopes in news and their features. Some of them are – Thirty Meter Telescope, Giant Metrewave Radio Telescope, Spitzer, Chandra etc.

    What is ASKAP?

    • ASKAP is a telescope designed over a decade ago and located about 800 km north of Perth.
    • It became fully operational in February 2019 and is currently conducting pilot surveys of the sky before it can begin large-scale projects from 2021 onward.
    • ASKAP surveys are designed to map the structure and evolution of the Universe, which it does by observing galaxies and the hydrogen gas that they contain.
    • One of its most important features is its wide field of view, because of which it has been able to take panoramic pictures of the sky in great detail.
    • The telescope uses novel technology developed by CSIRO- the Australian space agency, which is a kind of a “radio camera” to achieve high survey speeds and consists of 36 dish antennas, which are each 12m in diameter.
    • The survey team has been able to observe over 83 per cent of the sky visible from ASKAP’s site in Western Australia.

    Significance of the results

    • The present Rapid ASKAP Continuum Survey (RACS) taken by the ASKAP telescope is like a “Google map” of the Universe.
    • Mapping the Universe on such a scale enables astronomers to study the formation of stars and how galaxies and their supermassive black holes evolve and interact with each other.
    • Significantly, the images the telescope has taken are on average deeper and have better spatial resolution compared to those taken during other surveys of the sky.
    • The aim of the RACS survey is to generate images that will aid future surveys undertaken using the telescope.

  • Representation of Women in Judiciary

    Attorney-General has told the Supreme Court that more women judges in constitutional courts would certainly improve gender sensitivity in the judiciary.

    Q.Women judges could bring a more comprehensive and empathetic perspective of gender sensitivity in the judiciary. Discuss.

    Women in Judiciary: A dismal figure

    • The Supreme Court has only two women judges as against a sanctioned strength of 34 judges.
    • There has never been a female Chief Justice. This figure is consistently low across the higher judiciary.
    • There are only 80 women judges out of the sanctioned strength of 1,113 judges in the High Courts and the Supreme Court.
    • Only two of these 80 women judges are in the Supreme Court and the other 78 are in various High Courts, comprising only 7.2% of the number of judges.
    • There are six High Courts — Manipur, Meghalaya, Patna, Tripura, Telangana, and Uttarakhand — where there are no sitting women judges.

    A short timeline

    • The first female Judge appointed in Supreme Court was Justice M. Fathima Beevi from Kerala in 1987.
    • She was later followed by Justice Sujata V. Manohar from Maharashtra in 1994 and in the year 2000, Justice Ruma Pal was appointed from West Bengal.
    • And in the year 2010, Justice Gyan Sudha Misra from Bihar was appointed.
    • In 2014, Justice Ranjana Desai from Mumbai was appointed and currently, Justice R. Banumathi from Tamil Nadu is the only woman judge in Supreme Court.

    (Note: This data might be useful for State PSCs or other exams. UPSC aspirants need not remember this.)

    What did the A-G say?

    • Improving the representation of women could go a long way towards a more balanced and empathetic approach in cases involving sexual violence.
    • Judges need to be trained to place themselves in the shoes of the victim of sexual violence while passing orders, said the AG.
    • There is a dearth of compulsory courses in gender sensitization in law schools.
    • Certain law schools have the subject either as a specialization or as an elective.

    Why need more women in Judiciary?

    • The entry of women judges into spaces from which they had historically been excluded has been a positive step in the direction of judiciaries being perceived as being more transparent, inclusive, and representative.
    • By their mere presence, women judges enhance the legitimacy of courts, sending a powerful signal that they are open and accessible to those who seek recourse to justice.
    • They could contribute far more to justice than improving its appearance: they also contribute significantly to the quality of decision-making, and thus to the quality of justice itself.
    • Women judges bring those lived experiences to their judicial actions, experiences that tend toward a more comprehensive and empathetic perspective.
    • By elucidating how laws and rulings can be based on gender stereotypes, or how they might have a different impact on women and men, a gender perspective enhances the fairness of the adjudication.

  • [pib] E-Sanjeevani Telemedicine Service

    In a landmark achievement, eSanjeevani, Health Ministry’s national telemedicine initiative today completed 9 lakh consultations.

    Although telemedicine brings with it many benefits, there are some downsides to it as well. Discuss.

    What is E-Sanjeevani?

    • Ministry of Health & Family Welfare has launched two variants of eSanjeevani namely – doctor to doctor (eSanjeevani AB-HWC) in the hub and spoke model and patient to doctor (eSanjeevaniOPD).
    • E-Sanjeevani OPD (out-patient department) is a telemedicine variant for the public to seek health services remotely; it was rolled out on 13th of April 2020 during the first lockdown in the country.
    • It enables virtual meetings between the patients and doctors & specialists from geographically dispersed locations, through video conferencing that occurs in real-time.
    • At the end of these remote consultations, eSanjeevani generates electronic prescriptions which can be used for sourcing medicines.
    • Andhra Pradesh was the first state to roll out eSanjeevani AB-HWC services in November 2019.

    Benefits of telemedicine

    Telemedicine benefits patients in the following ways:

    • Transportation: Patients can avoid spending gas money or wasting time in traffic with video consultations.
    • No missing work: Today, individuals can schedule a consultation during a work break or even after work hours.
    • Childcare/Eldercare Challenges: Those who struggle to find care options can use telemedicine solutions.

  • 1.5x Formula for crops MSP calculation

    Talks between farmer unions and the government failed to reach a resolution. The main bone of contention in these talks is the Minimum Support Price (MSP) for crops, which farmers fear the new laws will do away.

    Try this:

    Q.There is also a point of view that agriculture produce market committees (APMCs) set up under the state acts have not only impeded the development of agriculture but also have been the cause of food inflation in India. Critically examine. (CSM 2014)

    What is MSP?

    • The MSP assures the farmers of a fixed price for their crops, well above their production costs.
    • MSP, by contrast, is devoid of any legal backing. Access to it, unlike subsidised grains through the PDS, isn’t an entitlement for farmers.
    • They cannot demand it as a matter of right. It is only a government policy that is part of administrative decision-making.
    • The Centre currently fixes MSPs for 23 farm commodities based on the Commission for Agricultural Costs and Prices (CACP) recommendations.

    Why in news yet again?

    • The Union Budget for 2018-19 had announced that MSP would be kept at levels of one and half times of the cost of production.
    • This year the govt. has increased the MSP for all mandated Kharif, Rabi and other commercial crops with a return of at least 50 per cent of the cost of production for the agricultural year 2018-19 and 2019-20.
    • This is the ambiguity from where this 1.5 times formula arrived at.

    How did the government fix the MSPs of crops before every planting season?

    • The CACP considered various factors while recommending the MSP for a commodity, including the cost of cultivation.
    • It also takes into account the supply and demand situation for the commodity; market price trends (domestic and global) and parity vis-à-vis other crops; and implications for consumers (inflation), environment (soil and water use) and terms of trade between agriculture and non-agriculture sectors.

    What changed with the 2018 budget?

    • The Budget for 2018-19 announced that MSPs would henceforth be fixed at 1.5 times of the production costs for crops as a “pre-determined principle”.
    • Simply put, the CACP’s job now was only to estimate production costs for a season and recommend the MSPs by applying the 1.5-times formula.

    How was this production cost arrived at?

    • The CACP projects three kinds of production cost for every crop, both at the state and all-India average levels.
    • ‘A2’ covers all paid-out costs directly incurred by the farmer — in cash and kind — on seeds, fertilisers, pesticides, hired labour, leased-in land, fuel, irrigation, etc.
    • ‘A2+FL’ includes A2 plus an imputed value of unpaid family labour.
    • ‘C2’ is a more comprehensive cost that factors in rentals and interest forgone on owned land and fixed capital assets, on top of A2+FL.

    Now try this PYQ:

    Q.The economic cost of food grains to the Food Corporation of India is Minimum Support Price and bonus (if any) paid to the farmers plus:

    (a) Transportation cost only

    (b) Interest cost only

    (c) Procurement incidentals and distribution cost

    (d) Procurement incidentals and charges for godowns

    Which production costs were taken in fixing the MSPs?

    • In 2018, then FM Arun Jaitley’s did not specify the cost on which the 1.5-times formula was to be computed.
    • But the CACP’s ‘Price Policy for Kharif Crops: The Marketing Season 2018-19’ report stated that its MSP recommendation was based on 1.5 times the A2+FL costs.

    What are the farmer’s demands?

    • Farm activists, however, had said that the 1.5-times MSP formula should have been applied on the C2 costs.
    • CACP considers A2+FL and C2 costs, both while recommending MSP. It reckons only A2+FL cost for return.
    • However, C2 costs are used by CACP primarily as benchmark reference costs (opportunity costs) to see if the MSPs recommended by them at least cover these costs in some of the major producing States.

  • What is the Emergency Use Authorization (EUA) for Drugmakers?

    The US drugmaker Moderna said it was applying for emergency use authorisation for its vaccine in India.

    Practice question for Mains:

    Q. What is Vaccine Nationalism? Discuss various ethical issues involved and its impact on vulnerable populations across the globe.

    Emergency Use Authorisation (EUA)

    • Vaccines and medicines, and even diagnostic tests and medical devices, require the approval of a regulatory authority before they can be administered.
    • In India, the regulatory authority is the Central Drugs Standard Control Organisation (CDSCO).
    • The approval is granted after an assessment of their safety and effectiveness, based on data from trials. In fact, approval from the regulator is required at every stage of these trials.
    • This is a long process, designed to ensure that medicine or vaccine is absolutely safe and effective.
    • The fastest approval for any vaccine until now — the mumps vaccine in the 1960s — took about four-and-a-half years after it was developed.

    Exceptions for emergency

    • In emergency situations, like the current one, regulatory authorities around the world have developed mechanisms to grant interim approvals.
    • However, there should sufficient evidence to suggest a medical product is safe and effective.
    • Final approval is granted only after completion of the trials and analysis of full data; until then, EUA allows the medicine or the vaccine to be used on the public.

    What is the process of getting a EUA in India?

    • India’s drug regulations do not have provisions for a EUA, and the process for receiving one is not clearly defined or consistent.
    • Despite this, CDSCO has been granting emergency or restricted emergency approvals to Covid-19 drugs during this pandemic — for remdesivir and favipiravir in June, and itolizumab in July.

    Associated risks

    • The public has to be informed that a product has only been granted a EUA and not full approval.
    • In the case of a Covid-19 vaccine, for example, people have to be informed about the known and potential benefits and risks.

    Not a compulsion

    • There has been an ongoing debate over whether people have the option of refusing to take the vaccine.
    • Incidentally, no country has made vaccination compulsory for its people.
    • Initially, all vaccines are likely to be deployed on emergency use authorizations only. Final approval from may take several months, or years.

  • Japan’s Hayabusa2 Probe

    Hayabusa2 Probe

    • Hayabusa2is an asteroid sample-return mission operated by the Japanese space agency, JAXA.
    • It follows on from the Hayabusa mission which returned asteroid samples in 2010.
    • It was launched on 3 December 2014 and rendezvoused with near-Earth asteroid 162173 Ryugu on 27 June 2018.
    • It surveyed the asteroid for a year and a half and took samples. It left the asteroid in November 2019.
    • It carries multiple science payloads for remote sensing, sampling, and four small rovers that investigated the asteroid surface to inform the environmental and geological context of the samples collected.
