  • WTO panel rules against India in IT tariffs dispute

     

    A World Trade Organization (WTO) panel has ruled that India has violated global trading rules in a dispute with the European Union (EU), Japan, and Taiwan over import duties on IT products.

    About World Trade Organization (WTO)

    Details
    Purpose Regulate and facilitate international trade between nations
    Establishment 1995
    Headquarters Geneva, Switzerland
    Membership 164 member countries as of 2023, representing over 98% of global trade
    Goal Promote free and fair trade by negotiating and enforcing rules and agreements governing international trade
    Agreements Administers a number of agreements, including GATT, SPS Agreement, and TRIPS Agreement
    Dispute Resolution Operates a dispute settlement system to resolve conflicts between member countries
    Technical Assistance Provides technical assistance and training to help developing countries participate more effectively in international trade
    Decision-Making Body Ministerial Conference, which meets every two years
    Director-General Chief executive responsible for overseeing the organization’s operations and activities
    Criticisms Some criticize the WTO for being undemocratic, favoring developed countries, and not doing enough to promote labor and environmental standards in international trade

     

    What was the case?

    • The case involved a dispute over India’s introduction of import duties ranging from 7.5% to 20% on a wide range of IT products, including mobile phones, components, and integrated circuits.
    • The EU, Japan, and Taiwan challenged these import duties in 2019, arguing that they exceeded the maximum rate allowed under global trading rules.
    • The recent ruling by the WTO panel found that India had violated these rules and recommended that India bring its measures into conformity with its obligations.

    WTO Panel’s Ruling

    • The WTO panel has ruled that India violated global trading rules by imposing these import duties.
    • The panel recommended that India bring these measures into conformity with its obligations.
    • While the panel broadly backed the complaints against India, it rejected one of Japan’s claims that India’s customs notification lacked “predictability”.

    Implications of the ruling

    • The EU is India’s third-largest trading partner, accounting for 10.8% of total Indian trade in 2021, according to the European Commission.
    • The ruling could have implications for trade relations between India and the EU, as well as Japan and Taiwan.
    • India may be required to lower or eliminate the challenged import duties.
    • It remains to be seen whether India will appeal against the ruling.
    • If it does, the case will sit in legal purgatory since the WTO’s top appeals bench is no longer functioning due to US opposition to judge appointments.

    Conclusion

    • The panel recommended that India bring such measures into conformity with its obligations, and it remains to be seen whether India will appeal against the ruling.
    • The case highlights the importance of complying with global trading rules and the role of the WTO in resolving trade disputes between countries.

     

  • What is Great Pacific Garbage Patch?

    pacific

    Central idea: The article reports on a recent study which found evidence that coastal life forms have colonized plastic items in the Great Pacific Garbage Patch, a vast area in the North Pacific Ocean where plastic waste has accumulated due to ocean currents.

    What is the Great Pacific Garbage Patch (GPGP)?

    Features
    Location North Pacific Subtropical Gyre (NPSG), north of the equator in the Pacific Ocean
    Currents Kuroshio, North Pacific, California, and North Equatorial currents, moving in a clockwise direction
    Sources Any trash that enters one of these currents from any of the 51 Pacific Rim countries
    Size Estimated to be 1.6 million sq. km
    Age More than 50 years old
    Plastic Content Estimated to contain 45,000-129,000 metric tonnes of plastic, predominantly in the form of microplastics
    Visible Objects Heavier, more visible objects that haven’t yet broken down into smaller particles accounted for 92% in 2018

     

    Findings of the new study

    • Researchers from Canada, the Netherlands, and the U.S. have reported that coastal life forms have colonized plastic items in the Great Pacific Garbage Patch.
    • From November 2018 to January 2019, they collected 105 pieces of plastic debris, the most heavily plastic-polluted ocean gyre on the globe.
    • Based on studying them, they reported that 98% of the debris items had invertebrate organisms.

    Plastic inflicting into a coastal organism

    • Organisms found on coasts were getting by on small floating islands of garbage out in the Pacific Ocean, which the researchers named the neopelagic community.
    • They found organisms belonging to 46 taxa, and 37 of them were coastal; the rest were pelagic. Among both coastal and pelagic organisms, crustaceans were the most common.
    • Nearly all taxa were of Northwest Pacific origin, including Japan.
    • Eight of the remainder were from East Asia and five specifically from Japan. Four items were from North America.
    • They found that 68% of the coastal taxa and 33% of the pelagic taxa reproduced asexually and that there was evidence of sexual reproduction among the hydroids and the crustaceans, among others.

    Implications of the findings

    • Marine plastic pollution has given rise to a new kind of standing coastal community in the open ocean.
    • The neopelagic community is not misplaced but lives on plastic items in the garbage patch, including reproducing there.
    • The finding recalls other studies that show the chemical bonding of plastic with rocks, sedimentary rocks embedded with plastic earrings in Brazil, and the formation of plastiglomerates in Hawaii.

     

    What is neopelagic community?

    • The neopelagic community refers to the group of organisms that inhabit the open ocean or the pelagic zone beyond the continental shelf.
    • It is characterized by deep waters with very few physical structures or substrate for organisms to attach to.
    • This community includes a wide variety of organisms, including zooplankton, fish, squid, and marine mammals, among others.
    • These organisms have adapted to survive in the open ocean environment, which can be quite challenging due to factors such as temperature fluctuations, limited food availability, and the absence of physical structures for shelter.
    • The neopelagic community is an important part of the global marine ecosystem, playing a key role in nutrient cycling and energy transfer between different levels of the food chain.

     

    GPGP and its impact on marine life

    • The GPGP has significant impacts on marine life due to the ingestion of plastic by marine animals, which can cause harm and even death.
    • Plastic can also entangle and suffocate marine animals, leading to the disruption of ecosystems.
    • The new study sheds light on the neopelagic community, which has adapted to living on plastic in the garbage patch.

    Plastic pollution and its environmental impact

    • Plastic pollution is a major environmental issue that affects land and water ecosystems worldwide.
    • Plastic waste can take hundreds of years to decompose, and even then, it breaks down into microplastics that can persist in the environment indefinitely.
    • The presence of plastic in the environment has negative impacts on biodiversity, ecosystem function, and human health.

    Conclusion

    • There are various solutions to plastic pollution, including reducing the use of single-use plastics, recycling, and promoting alternative materials.
    • Governments and industries can also take steps to reduce plastic waste, such as implementing policies and regulations that reduce plastic use and increase recycling.
    • Individual actions, such as reducing personal plastic consumption and properly disposing of plastic waste, can also make a difference.

     

  • What is Polar Crown Prominence (PCP)?

    crown

    Central idea: The article talks about an astrophotographer named Andrew McCarthy capturing an image of a plasma waterfall on the sun. The phenomenon is called Polar Crown Prominence (PCP).

    Polar Crown Prominence (PCP)

    • PCP is a solar phenomenon that occurs on the sun’s Polar Regions.
    • It is a type of solar prominence, which is a large, bright, gaseous feature that extends out from the sun’s surface.
    • A solar prominence is a large, bright, gaseous feature that extends out from the sun’s surface.
    • It is made up of ionized gas (plasma) that is held in place by magnetic fields.
    • Prominences are visible during total solar eclipses and can also be observed using specialized telescopes.
    • PCPs are often associated with sunspots, which are dark regions on the sun’s surface that are caused by magnetic activity.

    How are PCPs Formed?

    • PCPs are formed by the interaction of magnetic fields on the sun’s surface.
    • Magnetic fields are created by the movement of charged particles (plasma) in the sun’s interior.
    • When these magnetic fields interact, they can create regions of intense magnetic activity, such as sunspots.
    • PCPs are often associated with these regions of magnetic activity.

    Why are PCPs Important?

    • PCPs are important because they provide clues about the sun’s magnetic activity and how it affects the Earth’s environment.
    • Solar activity, including PCPs, can cause disturbances in the Earth’s magnetic field, which can lead to auroras and disruptions in communication systems.

     

     

  • India’s first Mangrove Pitta Birds Census conducted in Odisha

    pitta

    Central idea: The article talks about the first-ever census of mangrove pitta birds conducted in two coastal districts of Odisha, India.

    About Mangrove Pitta

    • The mangrove pitta (Pitta megarhyncha) belongs to the family of pittas, the Pittidae.
    • The mangrove pitta species is distributed in India, Bangladesh, Myanmar, Thailand, Malaysia, Singapore and Indonesia.
    • These pitta species have fragmented distribution and considered ‘Near Threatened’ by IUCN. These pittas are monotypic species.

    Focus of the Census

    • In this census, a total of 179 individual mangrove pitta birds were counted.
    • The census mainly focused on the mangrove patches along the coasts of Kendrapara and Jagatsingpur districts.
    • Information was collected on the distribution, habitat, and breeding of mangrove pittas along the coastal mangroves.
    • The census was carried out by point count method, either by walking in the forest or using country boats in the creeks.

  • Omicron evolved strategies to evade T Cell Immunity

    t cell

    Central idea: The SARS-CoV-2 virus has the ability to evade CD8 T cells, which are important in reducing the viral load and clearing the infection by detecting and killing infected cells.

    What is the news?

    • A recent study has revealed that the SARS-CoV-2 virus has the ability to modulate MHC I expression in host cells.
    • MHC I is crucial in alerting the immune system to virally infected cells.
    • The virus has evolved multiple strategies to inhibit MHC I expression, which is not seen in the case of the influenza virus.

    What is T Cell Immunity?

    • Like B cells, which produce antibodies, T cells are central players in the immune response to viral infection.
    • For your immune system to fight off any kind of invader, such as a virus, you need a kind of white blood cell called a B cell, which makes antibodies, and a similar-looking white blood cell called a T cell.
    • T cells can play different roles altogether.
    • They can act as “killer cells”, attacking cells which have been infected with a virus or another kind of pathogen, or they can act as “helper cells” by supporting B cells to produce antibodies.

    How do they function?

    • Alongside antibodies, the immune system produces a battalion of T cells that can target viruses.
    • Some of these, known as killer T cells (or CD8+T cells), seek out and destroy cells that are infected with the virus.
    • Others, called helper T cells (or CD4+T cells) are important for various immune functions, including stimulating the production of antibodies and killer T cells.
    • T cells do not prevent infection, because they kick into action only after a virus has infiltrated the body. But they are important for clearing an infection that has already started.
    • In the case of COVID-19, killer T cells could mean the difference between a mild infection and a severe one that requires hospital treatment.

     

     

  • In news: Pralay Ballistic Missile

    pralay

    India is going to buy 250 more Pralay ballistic missiles for the services to strengthen them on the northern borders, further boosting the firepower of the defence forces.

    Pralay Ballistic Missile

    • Pralay is a tactical missile developed from India’s K-series of submarine-launched ballistic missiles (SLBMs).
    • It has a range of 150-500 km and can carry warheads weighing between 350 to 700 kg.
    • The missile is a canisters road-mobile system, which enhances its mobility and allows for quick preparation and launch of the missile.
    • Pralay has the ability to perform manoeuvres in flight and follows a quasi-ballistic trajectory to maintain high speed, making it difficult for enemy missile defence systems to intercept.

    Classification

    • The Indian Defence Ministry has classified Pralay as a “conventional Surface-to-Surface missile”.
    • This distinguishes it from the Agni series of missiles, which have the capability to carry either conventional or nuclear warheads.

    Testing and launch

    • The missile was launched on a quasi-ballistic trajectory in one of the two tests, which enhances its effectiveness against enemy missile defence systems.
    • Satellite imagery of the test shows that Pralay is a canisterised road-mobile system, which adds to its mobility and flexibility in responding to evolving threats.

     

  • India’s Forex Reserves rise $6.30 bn to $584.75 bn

    forex

    India’s forex reserves increased by $6.306 billion to $584.755 billion last week, according to the Reserve Bank of India (RBI).

    Why discuss this?

    • In October 2021, India’s forex reserves reached an all-time high of $645 billion.
    • Since then, the reserves have been declining.

    What is Foreign Exchange (Forex) Reserve?

    • Foreign exchange reserves are important assets held by the central bank in foreign currencies as reserves.
    • They are commonly used to support the exchange rate and set monetary policy.
    • In India’s case, foreign reserves include Gold, Dollars, and the IMF’s quota for Special Drawing Rights.
    • Most of the reserves are usually held in US dollars, given the currency’s importance in the international financial and trading system.
    • Some central banks keep reserves in Euros, British pounds, Japanese yen, or Chinese yuan, in addition to their US dollar reserves.

    India’s forex reserves cover:

    1. Foreign Currency Assets (FCAs)
    2. Special Drawing Rights (SDRs)
    3. Gold Reserves
    4. Reserve position with the International Monetary Fund (IMF)

    Countries with the highest foreign reserves

    • Currently, China has the largest reserves followed by Japan and Switzerland.
    • India earlier overtook Russia to become the fourth-largest country with foreign exchange reserves. (Data from August 2022)
    1. China – $3,349 Billion
    2. Japan – $1,376 Billion
    3. Switzerland – $1,074 Billion
    4. Russia – $597.40 Billion

    Why are these reserves so important?

    • All international transactions are settled in US dollars and, therefore, required to support India’s imports.
    • More importantly, they need to maintain support and confidence for central bank action, whether monetary policy action or any exchange rate intervention to support the domestic currency.
    • It also helps to limit any vulnerability due to sudden disturbances in foreign capital flows, which may arise during a crisis.
    • Holding liquid foreign currency provides a cushion against such effects and provides confidence that there will still be enough foreign exchange to help the country with crucial imports in case of external shocks.

    Initiatives taken by the government to increase forex

    • To increase the foreign exchange reserves, the Government of India has taken many initiatives like AatmaNirbhar Bharat, in which India has to be made a self-reliant nation so that India does not have to import things that India can produce.
    • Other than AatmaNirbhar Bharat, the government has started schemes like Duty Exemption Scheme, Remission of Duty or Taxes on Export Product (RoDTEP), Nirvik (Niryat Rin Vikas Yojana) scheme, etc.
    • Apart from these schemes, India is one of the top countries that attracted the highest amount of Foreign Direct Investment, thereby improving India’s foreign exchange reserves.

  • NISAR to map Himalayas’ Seismic Zones

    nisar

    Central idea

    • The ISRO and the NASA have jointly developed a forthcoming satellite called NISAR.
    • It will map the most earthquake-prone regions in the Himalaya.

    What is NISAR?

    • NISAR stands for NASA-ISRO Synthetic Aperture Radar.
    • The mission aims to provide global measurements of the causes and consequences of land surface changes using advanced radar imaging.
    • The satellite is equipped with two types of synthetic aperture radars (SAR): L-band and S-band, which will allow for high-resolution, all-weather imaging of the Earth’s surface.
    • The NISAR satellite is expected to be launched in January 2024.

    How it will be used for earthquake monitoring?

    • It will generate data that can potentially give advance warning of land subsidence and identify places that are at greatest risk from earthquakes.
    • The geoscience community can use this to determine how strain is building up in various parts of the Himalayas.
    • Strain refers to the deformation that occurs in rocks when it is under pressure from other rocks.
    • Movements of continental plates that are sliding, colliding, or subducting against each other cause strain.
    • With a frequency of 12 days and the ability to provide images even under cloudy conditions, NISAR would be a valuable tool to study deformation patterns, such as in Joshimath.

    Strain Map already in place

    • In 2021, scientists from the Geological Survey of India published a “strain map” of the Himalayas based on data from 1,252 GPS stations along the Himalayas.
    • It identified regions that had the greatest odds of generating earthquakes of magnitude above 8 and their extent.
    • However, these many stations are still too few, and there’s only one satellite (Sentinel) that we rely on.
    • With NISAR, the costliest space mission ever, we can have a game-changer in earth-science observation.

     

    Seismic Zones of India

    nisar

    India is divided by Bureau of Indian Standards (BIS) into 4 seismic zones based on the level of seismicity and the frequency of earthquakes that occur in that particular region.

    These zones are as follows:

    1.      Zone 2: This is a low seismic zone comprising of areas with the lowest risk of earthquakes. It includes regions like the northeastern states of India, parts of J&K, Himachal Pradesh, and Uttarakhand.

    2.      Zone 3: This is a moderate seismic zone comprising of areas that are at moderate risk of earthquakes. It includes regions like Gujarat, Haryana, Delhi, parts of UP, Bihar, West Bengal, and parts of Jharkhand.

    3.      Zone 4: This is a high seismic zone comprising of areas that are at high risk of earthquakes. It includes regions like the A&N Islands, parts of Himachal Pradesh, J&K, Uttarakhand, and the entire northeastern region.

    4.      Zone 5: This is a very high seismic zone comprising of areas that are at the highest risk of earthquakes. It includes regions like the entire state of J&K, Himachal Pradesh, Uttarakhand, the entire northeastern region, parts of Gujarat, Rajasthan, Maharashtra, and the A&N Islands.

     

     

     

  • What is Magnetoresistance?

    magnet

     

    Researchers in the UK, led by Nobel laureate Andre Geim, have discovered magnetoresistance in graphene – a single-atom-thick layer of carbon atoms bonded in a honeycomb pattern – that further distinguishes this ‘wonder’ material.

    Graphene’s anomalous Giant Magnetoresistance (GMR)

    • Graphene displayed an anomalous giant magnetoresistance (GMR) at room temperature.
    • GMR is the result of the electrical resistance of a conductor being affected by magnetic fields in adjacent materials.
    • It is used in hard disk drives and magnetoresistive RAM in computers, biosensors, automotive sensors, micro-electromechanical systems, and medical imagers.

    What is GMR?

    • GMR is a phenomenon where the electrical resistance of a conductor is affected by magnetic fields in adjacent materials.
    • Say a conductor is sandwiched between two ferromagnetic materials (commonly, metals attracted to magnets, like iron).
    • When the materials are magnetised in the same direction, the electrical resistance in the conductor is low.
    • When the directions are opposite each other, the resistance increases.

    Significance of the finding

    • The magnetoresistance observed in the graphene-based device was almost 100 times higher than that observed in other known semimetals in this magnetic field range.
    • In the study, the magnetoresistance in monolayer graphene at 27º C held between two layers of boron nitride increased by 110% under a field of 0.1 tesla.
    • To compare, the magnetoresistance in these conditions increases by less than 1% in normal metals.
    • The team attributed this to the presence of a ‘neutral’ plasma and the electrons’ mobility.

    Try this MCQ

    Which of the following best describes magnetoresistance?

    (a) The magnetic resistance of a conductor to electrical current flow

    (b) The phenomenon where the electrical resistance of a conductor is affected by magnetic fields in adjacent materials

    (c) The ability of a conductor to produce a magnetic field when an electrical current is passed through it

    (d) The resistance of a magnet to demagnetization by an external magnetic field
