    ligo

    India has given the final approval to build its biggest scientific facility, Laser Interferometer Gravitational-Wave Observatory (LIGO), in the Hingoli district of Maharashtra. The facility will join the global project to detect and study gravitational waves.

    Gravitation and General Theory of Relativity

    • Newton’s law of gravitation, proposed by Sir Isaac Newton in the 17th century, explains that the force that makes an object fall to the ground is also responsible for making heavenly bodies go around in their orbits.
    • However, the theory did not explain the existence of an attractive force between any two bodies or the instantaneous propagation of the gravitational force over large distances.
    • In 1915, Albert Einstein proposed the General Theory of Relativity, which altered our understanding of gravitation. Einstein proposed that space-time interacted with matter, was influenced by it, and in turn, and influenced events.
    • The curvature in space-time produced by matter was the reason other smaller bodies in the vicinity felt the gravitational pull.
    • General Relativity also predicted that moving objects would generate gravitational waves in space-time.

    About LIGO-India

    • LIGO-India will be the fifth node of this international network of gravitational wave observatories, and possibly the last.
    • The instrument is so sensitive that it can easily get influenced by events like earthquakes, landslides, or even the movement of trucks, and produce a false reading.
    • That is why multiple observatories are needed to revalidate the signals.
    • India’s involvement in LIGO is crucial to demonstrating its intent and capability to pull-off complex science projects independently.

    Significance

    • The detection and study of gravitational waves could help in understanding the universe’s structure, the origin of the universe, and the functioning of black holes.
    • The LIGO project also has huge spin-off benefits for India’s science and technology sector.

     

  • Physicists discover new Uranium Isotope

    uranium

    Physicists in Japan have discovered a new isotope of uranium, with atomic number 92 and mass number 241.

    Uranium

    • Uranium is a naturally occurring chemical element with the symbol U and atomic number 92.
    • It is a heavy metal that is radioactive and found in small quantities in rocks and soils worldwide.
    • Uranium has several isotopes, which are atoms that have the same number of protons but different numbers of neutrons.

    Isotopes of Uranium

    The most common isotopes of uranium are uranium-238 and uranium-235.

    1. Uranium-238: It is the most abundant isotope of uranium, accounting for over 99% of natural uranium. It has 92 protons and 146 neutrons in its nucleus. It is not fissile, which means it cannot sustain a nuclear chain reaction. However, it is fertile, which means it can absorb neutrons and undergo radioactive decay to produce other isotopes such as plutonium-239, which is fissile.
    2. Uranium-235: It is the second most abundant isotope of uranium, accounting for less than 1% of natural uranium. It has 92 protons and 143 neutrons in its nucleus. Unlike uranium-238, it is fissile, which means it can sustain a nuclear chain reaction. It is used as fuel in nuclear reactors and as the primary material for nuclear weapons.

    How are isotopes created?

    • Isotopes can be created through natural processes or artificial processes in a laboratory.
    • Isotopes are created through natural processes such as radioactive decay, cosmic ray interactions, and nuclear fusion reactions in stars.
    • For example, carbon-14 is created in the Earth’s upper atmosphere when cosmic rays interact with nitrogen atoms.
    • Isotopes can also be created artificially through nuclear reactions.
    • This involves bombarding atoms with particles such as protons, neutrons, or alpha particles, which can change the number of protons and/or neutrons in the nucleus.

    How uranium-241 was found?

    • To find uranium-241, the researchers accelerated uranium-238 nuclei into plutonium-198 nuclei using the KEK Isotope Separation System (KISS).
    • In a process called multinucleon transfer, the two isotopes exchanged protons and neutrons, resulting in nuclear fragments with different isotopes.
    • The researchers identified uranium-241 and measured the mass of its nucleus using time-of-flight mass spectrometry.
    • Theoretical calculations suggest that uranium-241 could have a half-life of 40 minutes.

    Significance of the discovery

    • The discovery is significant because it refines our understanding of nuclear physics, particularly the shapes of large nuclei of heavy elements and how often they occur.
    • This information helps physicists to design models for nuclear power plants and exploding stars.

    Also, what are Magic numbers?

    • There is a particular interest in ‘magic number’ nuclei, which contain a certain number of protons or neutrons that result in a highly stable nucleus.
    • Lead (82 protons) is the heaviest known ‘magic’ nucleus, and physicists have been trying to find the next element with magic numbers.
    • The researchers hope to extend their systematic mass measurements towards many neutron-rich isotopes, at least to neutron number 152, where a new ‘magic number’ is expected.

    Conclusion

    • The discovery of the new neutron-rich uranium isotope is a major breakthrough in nuclear physics, as it provides essential information for understanding the behavior of heavy elements.
    • The researchers’ aim to extend their measurements to other neutron-rich isotopes reflects their commitment to exploring the frontiers of nuclear science and to improve our understanding of the universe.
    • Discovering new magic number nuclei through these measurements could have practical applications in designing safer and more efficient nuclear power plants and understanding the properties of exploding stars.

     

  • The Statistical Genius: C. R. Rao

    rao

    Central idea: Indian-American statistician Calyampudi Radhakrishna Rao has been awarded the 2023 International Prize in Statistics, which is considered the Nobel Prize for statistics.  He is 102 YO.

    Who is C. R. Rao?

    • R. Rao, is an Indian-American mathematician and statistician.
    • He is currently professor emeritus at Pennsylvania State University and Research Professor at the University at Buffalo.
    • Rao has been honoured by numerous colloquia, honorary degrees, and festschrifts and was awarded the US National Medal of Science in 2002.
    • The American Statistical Association has described him as “a living legend whose work has influenced not just statistics, but has had far reaching implications for fields as varied as economics, genetics, anthropology, geology, national planning, demography, biometry, and medicine.”
    • The Times of India listed Rao as one of the top 10 Indian scientists of all time.

    Rao’s Groundbreaking Paper

    • The research paper, “Information and accuracy attainable in the estimation of statistical parameters,” was published in 1945 in the Bulletin of the Calcutta Mathematical Society.
    • The paper provided a lower limit on the variance of an unbiased estimate for a finite sample, which has since become a cornerstone of mathematical statistics.

    Key outcomes of his research

    Rao’s 1945 paper has three outcomes-

    1. Cramer-Rao inequality: It provides a lower limit on the variance of an unbiased estimate for a finite sample.
    2. Rao-Blackwell Theorem: It provides a method to improve an estimate to an optimal estimate.
    3. Information geometry: It is a new interdisciplinary area called “information geometry,” which integrated principles from differential geometry into statistics, including the concepts of metric, distance, and measure.

  • TEMPO: NASA device to Monitor Air Pollution from Space

    tempo

    SpaceX Falcon 9 rocket successfully launched carrying a new NASA device named Tropospheric Emissions Monitoring of Pollution (TEMPO) designed to monitor air pollutants and their emission sources across North America from space more comprehensively than ever before.

    What is TEMPO?

    • TEMPO is an instrument developed by NASA, which will enable scientists to monitor air pollutants and their emission sources from space, down to the neighbourhood level.
    • This instrument will measure pollution and air quality across greater North America on an hourly basis during the daytime.

    TEMPO’s special features

    • TEMPO is unique because it will be hosted on an Intelsat communications satellite in geostationary orbit, about 22,236 miles (35,786 km) above the equator.
    • This will allow the instrument to match the rotation of the Earth, meaning it will stay over the same location (North America) at all times.
    • It will be able to measure atmospheric pollution down to a spatial resolution of 4 square miles (10 square km), or neighbourhood level.

    Applications of TEMPO

    • TEMPO will have multiple applications from measuring levels of various pollutants to providing air quality forecasts and helping the development of emission-control strategies.
    • The data will be used by the US Environmental Protection Agency (EPA), the National Oceanic and Atmospheric Administration (NOAA), and other agencies responsible for tackling atmospheric pollution.

    Importance of the mission

    • According to the American Lung Association, more than 40% of the US population, 137 million people, live in places with unhealthy levels of particle pollution or ozone, and air pollution is blamed for some 60,000 premature deaths a year.
    • TEMPO will track pollutants like nitrogen dioxide, produced from the combustion of fossil fuels, formaldehyde, and ozone.

  • RBI’s Pause On Repo Rate Hike: Concerns Over Inflation And Global Pressures Remain

    RBI

    Central Idea

    • The RBI has decided to not increase the repo rate amid continuing hikes by important central banks such as the US Federal Reserve (Fed) and European Central Bank (ECB), and domestic inflation concerns. However, if incoming data point to rising inflation risks, this decision could prove to be only a pause in the rate hiking cycle.

    The RBI’s decision to pause on rate hikes

    • The RBI feels that money market rates have effectively risen more than the 250-basis-point yank in the repo rate since May 2022, and hence it decided to pause and assess the impact of rate hikes.
    • The key reason behind the MPC decision is the expectation of a decline in inflation to 5.2% in the current fiscal, driven by a healthy rabi crop, normal monsoon, moderating international commodity prices, and the impact of rate hikes.
    • The RBI acknowledges the upside risks and stated its readiness to fight any unexpected rise in inflation.

    Impact on GDP growth

    • The RBI expects GDP growth to slow to 6% from 7% this fiscal as slowing global growth, domestic interest rates, and messy geopolitics bite.
    • Slowing global growth will be net negative for India’s exports, and the growing dependence on commodity exports makes India more vulnerable to global growth volatility.
    • Fiscal 2024 will, therefore, test the resilience of India’s domestic demand amid rising interest rates.

    Reasons for the expected cooling of consumer inflation

    • Fuel inflation expected to reduce: Fuel inflation is expected to reduce to 3% from a high of over 10% in the current fiscal because some easing of crude oil prices is likely as global growth slows down.
    • Decline in core inflation: Slowing domestic growth will ease core inflation from very sticky levels of over 6% last fiscal to 5.5% in the current one. However, the decline in core inflation will be limited as input cost pressures have not dissipated. To protect their margins, firms will continue to pass on input costs to end-consumer. Services inflation will also continue to exert pressure as the rotation of consumption demand from goods to services continues.
    • Moderate food inflation: Food inflation, which has a high weightage in the Consumer Price Index and has driven headline inflation in the past, is projected to moderate to slightly below 5%, assuming a normal monsoon. However, food inflation has always been volatile and carries upside risks largely because of climate-related factors affecting agriculture output and prices.

    How slowing global growth will have a negative impact on India’s exports?

    • The impact of the growth slowdown in the US and Europe is deeper than the recovery in China: The US and Europe have a combined GDP that is twice that of China. Therefore, the impact of the growth slowdown in the US and Europe will be deeper than the recovery in China. This will have a negative impact on India’s exports to the US and Europe.
    • India’s exports to the US and Europe are more than to China by a factor of six: India exports more to the US and Europe than to China by a factor of six. Therefore, the negative impact of the growth slowdown in the US and Europe will be felt more by India than by China.
    • India’s growing dependence on commodity exports makes it more vulnerable to global growth volatility: India’s exports of petroleum products and steel are growing, and this makes India more vulnerable to global growth volatility. As global growth slows down, demand for commodities is likely to decline, which will have a negative impact on India’s exports.

    External vulnerabilities

    • India’s external vulnerability is expected to decline with a narrower current account deficit (CAD) and modest short-term external debt.
    • The CAD is expected to narrow to 2% of GDP this fiscal from an estimated 2.5% last fiscal.

    Conclusion

    • The RBI’s decision to pause on rate hikes is driven by expectations of a decline in inflation. However, inflation risks remain, and the impact of rate hikes on GDP growth is expected to be significant. India’s external vulnerabilities are expected to decline, but the banking turmoil playing out amid interest rate hikes by important central banks and elevated debt levels remains a risk. The RBI’s decision to pause on rate hikes will be closely watched, and further rate hikes may be necessary if inflation risks persist.

    Mains Question

    Q. Enumerate the factors that led RBI to pause on rate hikes, and discuss the potential risks and impacts on the Indian economy?

  • What is the Open-Source Seeds Movement?

    seed

    Central idea

    • The article discusses the concept of open-source software and its parallels with open-source seeds.
    • Richard Stallman pioneered the Free Software Movement and developed the General Public License (GPL) to protect users’ rights and prevent code misappropriation.
    • Farmers have been innovating and sharing seeds without intellectual property rights (IPR) claims for centuries.

    Backgrounder: Plant Breeders’ Rights

    • Plant breeders’ rights (PBR) granted exclusive rights to breeders and developers of new varieties.
    • Farmers’ rights were limited under this regime.
    • The TRIPS agreement established a global IPR regime over plant varieties.
    • The consolidation of the seed sector raised concerns about the freedom to innovate.

    Forms of IPR Protection in Agriculture

    • There are now two forms of IPR protection in agriculture: PBR and patents.
    • Together, they restrict farmers’ rights and the freedom to develop new varieties.
    • The use of genetically modified seeds and IP claims triggered many problems, including State intervention on Bt cotton seeds in India.
    • The decline of public sector breeding and the dominance of the private sector in the seed sector increased the need for alternatives.

    What are Open Source Seeds?

    • The success of open-source software inspired a solution for seeds.
    • In 1999, a Canadian plant breeder named T.E. Michaels suggested an approach to seeds based on the principles of open-source software.
    • In 2012, Jack Kloppenburg launched the Open Source Seeds Initiative (OSSI) in Wisconsin.
    • Agrecol launched another initiative in Europe, and similar programs have come up worldwide.

    Open Source Seeds Initiatives in India

    • In India, the Hyderabad-based Centre for Sustainable Agriculture (CSA), part of the Apna Beej Network, developed a model incorporated into an agreement between CSA and the recipient of the seed/germplasm.
    • CSA’s Open Source Seeds Initiative uses a contracts approach similar to Agrecol’s strategy.
    • The number of seed firms using open-source models and the crop varieties and seeds made available thereunder is small but growing.
    • India is yet to test and adopt it widely.

    Potential Applications of Open-Source Seeds

    • Open-source principles can help promote farmer-led participatory plant-breeding exercises.
    • Traditional varieties often lack uniformity and aren’t of excellent quality, but open-source principles can facilitate testing, improvisation, and adoption.
    • Open-source principles can be used in farmer-led seed conservation and distribution systems.
    • The government and other stakeholders can consider adopting this approach to more widely adopt traditional varieties.

  • Tribes in news: Idu Mishmis

    mishmi

    Central idea

    • The National Tiger Conservation Authority has proposed to notify Dibang Wildlife Sanctuary in Arunachal Pradesh as a tiger reserve, causing concerns among the Idu Mishmi community.
    • The Idu Mishmi community has a unique cultural relationship with the forest, particularly with tigers.
    • This article explains who the Idu Mishmis are, their relationship with the forest, the move to propose a tiger reserve, and the community’s resistance.

    Who are the Idu Mishmis?

    • The Idu Mishmi community is a sub-tribe of the larger Mishmi group, primarily living in the Mishmi Hills bordering Tibet in Arunachal Pradesh.
    • The tribe has strong ties with the flora and fauna of the region, particularly tigers, which are considered their “elder brothers” in their mythology.
    • Despite traditional hunting practices, the tribe follows a belief system of myths and taboos that restrict them from hunting many animals, including a complete prohibition on killing tigers.
    • This belief system has led to a unique model of wildlife conservation, according to anthropologists and researchers.

    Overturning Dibang WLS into Tiger Reserve

    • Plans to declare Dibang Wildlife Sanctuary as a tiger reserve have been ongoing for a while now.
    • The sanctuary, home to rare Mishmi takin, musk deer, goral, clouded leopards, snow leopards, and tigers, was notified in 1998.
    • The Wildlife Institute of India carried out a survey in 2014 to determine the presence of tigers in the area based on photographic evidence via camera trapping.
    • The study recorded the presence of tigers in the highest reaches of the Mishmi Hills, forming the basis of the proposal to declare the sanctuary as a tiger reserve.

    Why are the Idu Mishmis resisting the move?

    • The community’s access to the Dibang forests has not been impacted as a wildlife sanctuary, but many believe a tiger reserve would increasingly restrict access.
    • The upgrade to a tiger reserve would feature stricter security measures, such as a ‘Special Tiger Protection Force,’ which would hinder the community’s access to their forest lands.
    • The community has declared part of its forest land as a ‘Community Conserved Area,’ governed entirely by local populations, where they ban hunting, felling trees, and implement other conservation measures.
    • The community alleges that the Dibang WLS was created without their consent or knowledge.
