    Longitude Prize on Antimicrobial Resistance (AMR)

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Longitude Prize, AMR

    Why in the News?

    Sysmex Astrego, a Sweden-based diagnostic company, won the £10 million Longitude Prize for developing a high-tech UTI (Urinary Tract Infection) test called the PA-100 AST System. 

    What is Antimicrobial Resistance?

    • Antimicrobial Resistance (AMR) occurs when bacteria, viruses, fungi, and parasites change so that medicines no longer work against them.
    • This makes infections harder to treat and can lead to more severe illness and even death.
    • AMR can occur naturally through genetic changes or when one type of microorganism picks up resistance from another.
    • It can also occur randomly due to mutations or when resistant genes spread between different organisms.
    • The main reasons for AMR are antibiotics incorrectly or too often, not having access to clean water and good hygiene, not doing enough to prevent infections, and people not knowing how to use antibiotics properly.

    Global Impact of AMR

    • Global Threat: Antibiotic-resistant infections caused nearly 1.3 million deaths in 2019, with projections to exceed cancer-related deaths by 2050.
    • Economic Impact: The global economy faces potential losses of up to 4 trillion by 2030 and 100 trillion by 2050 due to the AMR crisis.

    About the Longitude Prize

    • The Longitude Prize, valued at £8 million (₹85 crore), was recently awarded for its profound implications in combating antimicrobial resistance (AMR).
    • The prize launched in 2014, aims to revolutionize infection management globally.
    • Historical Context:  
      • Origins: Established in 1714 to solve the maritime longitude problem, demonstrating the critical need for accurate navigation.
      • Modern Application: The 21st-century Longitude Prize addresses pressing global challenges like AMR, incentivizing innovative solutions.
    • Goal of the Prize:
      •  Aims to replace current lab-based diagnostic methods with rapid tests that guide targeted antibiotic therapies, combating AMR effectively.

    About PA-100 AST System 

    • Technology Breakthrough: Developed by Sysmex Astrego, this system uses a phenotypic test that identifies UTI bacteria and performs antibiotic susceptibility testing in under 45 minutes.
    • Operation: A single-use cartridge processes less than half a milliliter of urine, using microfluidic traps and phase-contrast imaging in a shoe box-sized reader instrument.
    • Clinical Impact: Provides rapid “sensitive” or “resistant” results for antibiotics, aiding doctors in immediate, accurate treatment decisions at the point of care.

    Current Challenges in UTI Diagnosis

    • Limited Accuracy: Current options include urine dipstick tests for quick results but limited accuracy (50-60%) and lab cultures with 2-3 day turnaround times.
    • Impact on Treatment: Delayed diagnosis often leads to empirical antibiotic use, contributing to antibiotic resistance worldwide.

    Significance for India

    • Healthcare Burden: In India, millions seek treatment for UTIs annually, impacting lives and healthcare systems significantly.
    • Potential: Rapid, accurate point-of-care tests could revolutionize UTI management globally, saving lives and reducing healthcare costs.

    PYQ:

    [2014] Can overuse and free availability of antibiotics without a Doctor’s prescription be contributors to the emergence of drug-resistant diseases in India? What are the available mechanisms for monitoring and control? Critically discuss the various issues involved.

    [2019] Which of the following are the reasons for the occurrence of multi-drug resistance in microbial pathogens in India?

  • Air Pollution

    India is the World’s Second Largest emitter of Nitrous Oxide

    Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Nitrous Oxide pollution

    Why in the News?

    • India ranks as the world’s second-largest contributor (after China) to nitrous oxide (N2O), a potent greenhouse gas (GHG), accounting for approximately 11% of global man-made emissions in 2020 as per data published in the journal Earth System Science Data.
      • The top five country emitters by volume of anthropogenic N2O emissions in 2020 were China (16.7%), India (10.9%), the United States (5.7%), Brazil (5.3%), and Russia (4.6%).

    About Nitrous Oxide

    • Nitrous oxide (N2O), a colourless and odourless gas, is a potent greenhouse gas, 300 times more powerful than CO2. Despite its small atmospheric fraction, it ranks third in concentration after CO2 and methane (CH4). It’s a crucial target for environmental research and efforts to mitigate climate change impacts.

    Sources of Emission:

    1. Natural Sources: N2O is naturally produced in processes such as microbial nitrogen cycling in soil and water bodies, volcanic activity, and biomass burning.
    2. Anthropogenic Activities: Human activities significantly contribute to N2O emissions, with the primary sources being:
    • Agricultural practices, including the use of nitrogen-based fertilizers and animal manure.
    • Industrial processes such as combustion of fossil fuels and wastewater treatment.
    • Combustion of biomass and waste.
    • Use of nitrous oxide in medical and dental procedures (as a sedative) and in food packaging.

    Impact on Climate Change:

    • Greenhouse Gas: N2O is a potent greenhouse gas with a global warming potential (GWP) much higher than that of carbon dioxide (CO2).
    • Ozone Depletion: In addition to its role in climate change, N2O also contributes to ozone depletion in the stratosphere, further exacerbating environmental concerns.

    Environmental and Health Effects:

    • Environmental Pollution: N2O emissions can lead to pollution of soil, water bodies, and air, affecting ecosystems and human health.
    • Health Risks: While N2O is relatively non-toxic at ambient levels, prolonged exposure or high concentrations can pose health risks, including respiratory issues and neurological effects.

    Global Nitrous Oxide Emissions

    • Atmospheric Concentration: The concentration of atmospheric N2O reached 336 parts per billion in 2022, about 25% above pre-industrial levels.
    • Next to Carbon Emissions: In comparison, the concentration of carbon dioxide was 417 parts per million in 2022.
    • Persistent Lifespan: Once emitted, N2O stays in the atmosphere for longer than the average human lifespan (117 years), making its climate and ozone impacts long-lived.
    • Contribution to Climate Change: These emissions are responsible for 6.4% of the effective radiative forcing of greenhouse gases and have added about 0.1°C to current global warming.
    • Impact of Nitrogen Fertilizers: N2O emissions from human activities have increased by 40% in the past four decades, with agricultural production using nitrogen fertilizers and animal manure contributing 74% of total anthropogenic N2O emissions in the last decade.

    Call for Action and Future Outlook

    • Scientists warn that anthropogenic N2O emissions must decline by at least 20% relative to 2019 levels by 2050 to align with net-zero emission pathways consistent with the Paris Agreement.
    • Nitrogen fertilizers, which are heavily subsidized in India, contribute significantly to N2O emissions. Urgent reforms are needed to promote alternative production systems and mitigate emissions.

    India’s Policy Initiatives to Curb Nitrogen Pollution

    • Nutrient-Based Subsidy (NBS) (2010): This policy encourages the adoption of controlled-release fertilizers to enhance nutrient management efficiency.
    • Soil Health Cards (2015): Provided to farmers, these cards offer insights into soil nutrient levels and tailored fertilizer recommendations, promoting balanced nutrient application.
    • Bharat Stage (BS VI) Emission Standards (2016): These stringent regulations for vehicles and industries aim to reduce the emission of nitrogen oxides and particulate matter, thereby mitigating air and water pollution.
    • Nano Urea (2021): Marketed by the Indian Farmers Fertiliser Cooperative Limited (IFFCO), Nano Urea is a patented fertilizer approved for commercial use, designed to curb excessive and indiscriminate conventional urea use while boosting crop yields.

    PYQ:

    [2016] Why does the Government of India promote the use of ‘Neem-coated Urea’ in agriculture?

    (a) Release of Neem oil in the soil increases nitrogen fixation by the soil microorganisms

    (b) Neem coating slows down the rate of dissolution of urea in the soil

    (c) Nitrous oxide, which is a greenhouse gas, is not at all released into the atmosphere by crop fields

    (d) It is a combination of a weedicide and a fertilizer for particular crops

    N332-GT5 and eOD-GT8: Advancements in HIV Vaccine Development

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: N332-GT5, eOD-GT8, HIV-AIDS

    Why in the News?

    Researchers at the Duke Human Vaccine Institute have successfully induced broadly neutralising antibodies (bNAbs) against HIV (human immunodeficiency virus) through vaccination for the first time.

    About HIV/AIDS:

    • Emergence: The first cases of AIDS (Acquired Immunodeficiency Syndrome) were reported in the early 1980s, primarily among gay men in the United States.
    • Discovery of HIV: In 1983-1984, scientists identified HIV (Human Immunodeficiency Virus) as the cause of AIDS.
    • Global Spread: HIV/AIDS quickly became a global pandemic, affecting millions of people worldwide.

    Causes:

    • HIV is transmitted through contact with certain body fluids of an infected person, including blood, semen, vaginal fluids, and breast milk.
    • Common modes of HIV transmission include unprotected sexual intercourse, sharing needles or syringes, and from mother to child during pregnancy, childbirth, or breastfeeding.

    Symptoms:

    • Acute HIV Infection: Many people experience flu-like symptoms, such as fever, headache, fatigue, and swollen lymph nodes, within 2-4 weeks after infection.
    • Asymptomatic Stage: After the initial symptoms subside, HIV often enters a latent stage where individuals may not experience any symptoms for years.
    • Progression to AIDS: Without treatment, HIV gradually weakens the immune system, leading to the development of opportunistic infections and cancers. This advanced stage is known as AIDS and is characterized by severe immune deficiency.

    Vaccines Development:

    • Challenges: Developing an HIV vaccine has been challenging due to the virus’s ability to mutate rapidly and evade the immune system.
    • Vaccine Candidates: Numerous vaccine candidates have been tested over the years, but none have yet been successful in providing robust protection against HIV infection.
    • Hope for the Future: Despite setbacks, advances in vaccine development, such as the identification of promising candidates like N332-GT5 and eOD-GT8, offer hope for eventually achieving an effective HIV vaccine.

    How B cells and mRNA play distinct roles in the context of HIV infection?

    1.    B cells (B lymphocytes):

    • B cells are a type of white blood cell crucial for the immune response.
    • In HIV infection, B cells participate in the adaptive immune response by producing antibodies specific to HIV antigens.
    • These antibodies can neutralize HIV particles, tag infected cells for destruction by other immune cells, and contribute to the immune memory against HIV.

    2.    mRNA (messenger RNA):

    • mRNA is a molecule that carries genetic information from DNA to the ribosomes, where proteins are synthesized.
    • In the context of HIV, mRNA is involved in the replication process of the virus.
    • HIV uses its RNA genome to produce viral mRNA, which directs the synthesis of viral proteins necessary for the assembly of new virus particles.
    • Understanding HIV mRNA is crucial for developing antiviral therapies that target viral replication, such as mRNA-based vaccines or mRNA inhibitors.

    N332-GT5 and eOD-GT8: The New Vaccines in Making

    • N332-GT5: This vaccine candidate targets a specific region on the surface of the HIV virus known as the N332 glycan site. By engaging B-cells that have the potential to produce bNAbs against this site, N332-GT5 aims to stimulate the immune system to generate a protective response against a wide range of HIV strains.
    • eOD-GT8: Similarly, eOD-GT8 is designed to target another region on the HIV virus, known as the eOD protein. By leveraging nanoparticles as carriers, eOD-GT8 aims to enhance the immune system’s ability to recognize and neutralize HIV, ultimately leading to the production of bNAbs.

    What are Broadly Neutralizing Antibodies (bNAbs)?

    • In the 1990s, scientists discovered that some HIV-infected individuals produced bNAbs, which neutralize many viral strains.
    • bNAbs target viral protein areas crucial for infectivity, making them less likely to change.
    • Despite their effectiveness, bNAbs take years to develop, by which time HIV has often evolved to escape them.

    Developing bNAb-Based Vaccines

    • The goal is to make the immune system produce bNAbs quickly in response to a vaccine.
    • Germline targeting involves three steps:
      1. Identify and engage B-cells capable of producing bNAbs.
      2. Use a booster to guide these cells to produce stronger bNAbs.
      3. Refine bNAbs to neutralize a wide range of HIV strains.

  • Special Category Status and States

    Bihar’s call for Special Category Status | Explained

    Prelims Only | Polity | Mains Paper 2: Federalism

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Specific criteria qualify a State for special category status

    Mains level: Special category status benefits to States like Bihar

    Why in the News?

    Bihar Chief Minister Nitish Kumar has renewed the State’s persistent call for special category status from the Centre, which would boost the State’s share of tax revenues from the Central government.

    How does the ‘Special Category’ Status benefit the states like Bihar?

    • Increased Central Funds: States with special category status receive a higher share of central funds for government schemes, typically 90% from the Centre, compared to 60%-80% for other states.
    • Tax-Related Concessions: These states enjoy various tax concessions that can attract investments and boost economic development.
    • Financial Aid for Development: The additional funds can be used to address developmental gaps, improve infrastructure, and support welfare programs.

    Criteria for Special Category status:

    • Geographic Disadvantages: States with challenging terrains such as hilly or difficult terrain.
    • Low Population Density or High Tribal Population: States with a considerable proportion of tribal population or low population density.
    • Economic and Social Backwardness: States that are economically and socially disadvantaged.
    • Strategic Location: States that share international borders or have strategic significance.

    Why has Bihar’s demand been a long-standing issue?

    • Economic Backwardness: Bihar has one of the lowest per capita incomes in India and lags behind in several human development indicators.
    • Fiscal Challenges: The bifurcation of the state leading to the formation of Jharkhand, frequent natural disasters, and insufficient water resources for irrigation have adversely affected Bihar’s fiscal situation.
    • Political Reiteration: Successive Bihar governments have continuously demanded special status to help the state’s development.

    What are the political implications of granting ‘Special Status’ to Bihar?

    • Increased Bargaining Power: Granting special status could enhance Bihar’s political leverage with the central government, especially in coalition politics.
    • Precedent for Other States: Granting special status to Bihar could lead to similar demands from other states, potentially creating financial burdens for the Centre.
    • Electoral Promises and Alliances: Political parties may use the promise of special status as an electoral tool to gain or maintain power, as seen with the Congress party’s manifesto promise in 2024.
    • Centre-State Relations: The decision could impact the dynamics of center-state financial relations and influence the federal structure of revenue distribution in India.

    Conclusion: The Central government should establish a transparent and well-defined framework for granting special category status, taking into account various economic, geographic, and social parameters. This framework should be periodically reviewed to ensure it remains relevant and fair to all states.

    2025 to be International Year of Quantum Science and Technology

    Prelims Only | Science Tech | Mains Paper 3:

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Quantum Theory and related Researches, National Quantum Mission (NQM)

    Why in the News?

    • The United Nations has designated 2025 as the ‘International Year of Quantum Science and Technology’ to increase public awareness about the significance of quantum science and its applications.
      • This initiative, led by Mexico and supported by nearly 60 countries, aims to promote activities at all levels to highlight the importance of quantum science and technology worldwide.

    International Year of Quantum S&T

    • Growing Relevance: Quantum science and technologies, especially quantum computing, have gained prominence in public discourse due to their potential transformative impact on various fields.
    • Anniversary of Heisenberg’s Work: The proclamation coincides with the upcoming centenary of Werner Heisenberg’s groundbreaking paper on quantum mechanics, published in 1925.
    • Support from International Bodies: The proclamation has received endorsements from various international organisations, including the International Union of Pure and Applied Physics and the International Union of Pure and Applied Chemistry.

    What does one mean by Quantum?

    • “Quantum” refers to the smallest discrete unit of any physical quantity involved in an interaction according to quantum theory.
    • In classical physics, many properties, such as energy and momentum, are thought to be continuous and infinitely divisible.
    • However, in quantum mechanics, certain properties, like energy levels and the behaviour of particles, are quantised, meaning they can only exist in specific discrete amounts or levels.

    What is Quantum Theory?

    • Quantum theory is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles.
    • Quantum mechanics differs from classical physics in that energy, momentum, and angular momentum.

    Development in Quantum Theory So Far

    • Planck’s assumption: In 1900, Planck made the assumption that energy was made of individual units or quanta.
    • Albert Einstein’s theory: In 1905, Albert Einstein theorized that not just the energy, but the radiation itself was quantized in the same manner.
    • Louis de Broglie theory: In 1924, Louis de Broglie proposed that there is no fundamental difference in the makeup and behaviour of energy and matter; on the atomic and subatomic level either may behave as if made of either particles or waves. This theory became known as the principle of wave-particle duality: elementary particles of both energy and matter behave, depending on the conditions, like either particles or waves (wave-particle duality).
    • Heisenberg proposed: In 1927, Werner Heisenberg proposed that precise, simultaneous measurement of two complementary values – such as the position and momentum of a subatomic particle – is impossible. Contrary to the principles of classical physics, their simultaneous measurement is inescapably flawed; the more precisely one value is measured, the more flawed will be the measurement of the other value. This theory became known as the uncertainty principle, which prompted Albert Einstein’s famous comment, “God does not play dice.”

    What is Entanglement?

    • Entanglement was another of several weird properties exhibited by these tiny particles.
    • Two particles, having ‘interacted’ with each other at some stage, were found to have got ‘entangled’ in a way that the behaviour of one produced an instantaneous reaction in the other even if the two were no longer connected in any way and were separated by very large distances.
    • The entanglement property opened up new technological possibilities first time that it was possible to ‘teleport’ the quantum states of a particle to another location without the particle moving anywhere and without a medium.

    What is Superposition?

    • It’s a phenomenon where, a particle exists simultaneously at multiple locations, known as superposition.
    • The chance of finding the particle at any given place was dictated by probabilistic calculations, and once it was found, or observed, at one location, it ceased to exist at all other places.

    What is Quantum Computing?

    • Quantum computing is a new and super powerful way of doing computer stuff.
    • Instead of using regular computer bits that are either 0 or 1, quantum computers use special bits called qubits that can be both 0 and 1 at the same time, thanks to a thing called “quantum superposition.”
    • This allows them to do lots of calculations all at once, making them really fast at solving certain types of problems.
