  • Why is India seeking Self-sufficiency in Pulses?

    Why in the News?

    India, though the world’s largest producer and consumer of pulses, continues to face chronic supply-demand imbalance, threatening food security and farm incomes.

    Introduction  

    • The Union Cabinet (1 October 2025) approved the â‚č11,440 crore “Mission for Atmanirbharta in Pulses”, a 6-year programme (FY26–FY31) to achieve self-sufficiency in pulse production.
    • The initiative responds to surging imports of $5.5 billion in FY25, the highest ever, amid stagnating domestic yields and acreage.
    • India, though the world’s largest producer and consumer of pulses, continues to facea  chronic supply-demand imbalance, threatening food security and farm incomes.

    Value Addition: Pulses and their Production in India

    • Overview: Pulses are edible seeds of leguminous plants (family Fabaceae), cultivated for dry grains such as gram, tur, urad, masoor, and moong.
    • Nutritional Role: Rich in protein, fiber, micronutrients, and amino acids; low in fat and vital for nutritional security.
    • Agro-Climatic Range: Grown in both kharif and rabi seasons, requiring 20–27°C temperature and 25–60 cm rainfall.
    • Production Share: India produces ~25 million tonnes, accounting for 25% of global output, yet consumes 27%, making it the largest producer, consumer, and importer.
    • Crop Composition: As per FY2024, Gram (~40%), Tur/Arhar (15–20%), Moong/Urad (8–10%) dominate; pulses occupy 20% of grain area but only 7–10% of total foodgrain output.
    • Regional Spread: Major producers are- Madhya Pradesh, Maharashtra, Rajasthan, UP, Karnataka.
    • Crop Share: Pulses occupy 20 % of grain area but yield only 7–10 % of output; gram 40 %, tur 15–20 %, moong/urad 8–10 %.

    Why Farmers shifted away from Pulses?

    1. Price Disparity: Market prices often 14–28% below MSP, due to cheap imports (e.g., yellow peas from Canada at â‚č3,000/quintal vs MSP â‚č5,875).
    2. Import Competition: Duty-free imports from Canada, Australia, Mozambique, Myanmar suppress domestic demand.
    3. Policy Bias: Procurement, subsidies, and irrigation facilities favour rice and wheat, not pulses.
    4. Low Productivity: Pulses mostly grown on rain-fed, marginal lands, highly vulnerable to droughts, erratic monsoons, and poor irrigation.
    5. Market Risk: Weak procurement and delayed payments reduce confidence in government price support.
    6. Limited R&D: Poor availability of improved seed varieties and inadequate extension support for pest management and soil health.

    Key Structural Challenges:

    1. MSP and Procurement Gaps: Inconsistent purchase operations discourage adoption of pulses over cereals.
    2. Climatic Vulnerability: Rain-fed dependence leads to high risk from El Niño, floods, or dry spells.
    3. Low Yields: National average at 740 kg/ha, below global mean of 949 kg/ha and far below Canada/USA (1,800+ kg/ha).
    4. Small Landholdings: Over 85% small and marginal farmers lack capital for irrigation and mechanisation.
    5. Soil and Pest Constraints: Nutrient deficiency, salinity, and frequent pest attacks hinder productivity.
    6. Institutional Weakness: Fragmented R&D ecosystem and weak integration between seed research, extension, and procurement systems.

    Import Trends and Dependence:

    • Import Bill Growth: From $1.6 billion (FY21) to $5.5 billion (FY25) i.e a 3.4× surge.
    • Sources: Australia and Canada (peas), Myanmar, Tanzania, Mozambique (tur/arhar).
    • Volume: 7.3 million tonnes imported in 2024-25 surpassing the 2016-17 record.
    • Drivers: Stagnant domestic output (~25 Mt for five years) and rising urban consumption.
    • Top Importers: Canada, Russia, Australia, Mozambique, Tanzania, Myanmar, USA.

    Economic and Social Dimensions:

    • Production Rise: From 19.2 Mt (FY14) to 24.4 Mt (FY24), yet consumption still exceeds supply.
    • Consumption Growth: Rising incomes and protein awareness push demand upward.
    • Trade Imbalance: India remains both largest producer (25 %) and largest importer (14 %) of global pulses.

    Benefits of Pulses Cultivation:

    1. Environmental Sustainability: Pulses require less water and lower chemical inputs than cereals.
    2. Soil Fertility: Through biological nitrogen fixation, they enrich soil nitrogen, improving yield for subsequent crops.
    3. Reduced Fertilizer Use: Lower dependence on synthetic urea reduces subsidy burden and emissions.
    4. Soil Structure and Water Retention: Root systems enhance porosity, carbon content, and microbial biodiversity.
    5. Pest and Disease Management: Crop rotation with pulses suppresses soil-borne pathogens and reduces pesticide dependency.
    6. Carbon Sequestration: Residue incorporation increases soil organic carbon, mitigating greenhouse gas emissions.
    7. Economic Efficiency: Arvind Subramanian Committee (2016) estimated a â‚č13,000/ha higher social benefit for Tur vis-Ă -vis rice cultivation due to water and emission savings.

    Way Forward:

    1. Seed Innovation: Intensify research through ICAR–IIPR and utilise India’s 70,000 germplasm accessions for high-yielding, climate-resilient strains.
    2. Area Expansion: Promote rice-fallow pulse rotation in eastern India and intercropping systems in semi-arid regions.
    3. Assured Procurement: Scale up NAFED and NCCF-led MSP operations, ensuring timely payments.
    4. Infrastructure Support: Strengthen warehousing, milling, and processing hubs near production clusters.
    5. Import Rationalisation: Impose variable tariffs to protect domestic farmers from global price volatility.
    6. Sustainability Integration: Incentivise pulse cultivation under carbon farming and sustainable agriculture missions.

    PYQ Relevance:

    [UPSC 2017] Mention the advantages of the cultivation of pulse because of which the year 2016 was declared as the International Year of Pulses by the United Nations.

    [UPSC 2020] With reference to pulse production in India, consider the following statements:

    1. Black gram can be cultivated as both kharif and rabi crop.

    2. Green gram alone accounts for nearly half of pulse production.

    3. In the last three decades, while the production of kharif pulses has increased, the production of rabi pulses has decreased.

    Which of the statements given above is/are correct?

    (a) 1 only * (b) 2 and 3 only (c) 2 only (d) 1, 2 and 3

     

    Linkage: Pulses imports often strain the Balance of Payments (BoP) and affect food inflation (a topic tested in 2024 Mains). Achieving self-sufficiency saves foreign exchange and helps manage domestic price volatility.

     

  • Are workers’ rights being eroded?

    Introduction / Context

    • Recent Disasters: In 2025, three major industrial accidents — the Sigachi Industries chemical blast in Telangana (June 30), the Gokulesh Fireworks explosion in Sivakasi (July 1), and the Ennore Thermal Power Station collapse in Chennai (September 30) — killed nearly 60 workers within three months.
    • Scale of the Problem: According to the British Safety Council, one in four fatal workplace accidents globally occurs in India, though actual figures are higher due to underreporting in informal sectors.
    • Structural Failure: These tragedies expose a systemic breakdown in safety enforcement, where profit maximisation overrides worker protection.

    Why Workplace Accidents Occur

    1. Preventable Failures: Most industrial accidents occur due to negligence in hazard prevention such as poor equipment design, absence of alarms, and lack of maintenance.
    2. Telangana Case: The chemical reactor was operated at twice its safe limit, safety alarms failed, and untrained contract workers were deployed without records or protection.
    3. ILO Findings: The International Labour Organization (ILO) attributes most accidents to cost-cutting by managements, not random chance or individual mistakes.
    4. Human Error Myth: Employers blame workers for “human error”, but systemic issues like excessive work hours, fatigue, and exploitative conditions are the root causes.
    5. Lack of Safety Oversight: The absence of mandatory inspections and safety officers allows hazardous practices to continue unchecked.

    Evolution of Workplace Safety Laws in India

    1. Colonial Roots: The first Factories Act of 1881 was enacted under British rule to regulate working hours and conditions in textile mills.
    2. Post-Independence Framework: The Factories Act of 1948 became the foundation of India’s occupational safety regime, covering licensing, rest periods, and machine maintenance.
    3. Bhopal Legacy: The 1987 Amendment followed the Bhopal Gas Tragedy, introducing stricter safety clauses but failing in enforcement due to bribery and falsified records.
    4. Compensation Mechanisms: The Workmen’s Compensation Act (1923) and Employees’ State Insurance Act (1948) provide for injury and income loss but remain financially inadequate.
    5. Lack of Criminal Accountability: Employers rarely face criminal charges for fatal negligence; compensation is often paid through government relief funds, not company liability.

    Post-Liberalisation Deregulation and Impact

    1. Shift in Policy: Since the 1990s, India’s industrial policy has prioritised labour flexibility over worker protection.
    2. Self-Certification: States like Maharashtra (2015) allowed industries to self-certify compliance, effectively dismantling inspection-based oversight.
    3. Ease of Doing Business: Safety rules are now portrayed as regulatory hurdles, diluting mandatory standards for inspection and reporting.
    4. Contract Labour Expansion: Informal and outsourced workforces dominate hazardous sectors, operating without registration or legal protection.
    5. Erosion of State Capacity: Labour departments have been underfunded and depowered, reducing preventive enforcement to mere paperwork.

    The Occupational Safety, Health and Working Conditions (OSHWC) Code, 2020

    1. Purpose: Consolidates 13 older laws including the Factories Act (1948), Mines Act (1952), and Contract Labour Act (1970) into one unified framework.
    2. Scope: Applies to all workplaces with 10 or more workers and covers mines, docks, and factories.
    3. Employer Duties: Mandates risk-free work environments, medical check-ups, and welfare amenities, with provisions for National and State Safety Boards.
    4. Penalties: Prescribes monetary penalties for violations and limited punishment for accidents causing death.
    5. Criticism: The Code converts safety from a statutory right to administrative discretion, weakening enforceability and inspection mechanisms.

    Other Key Labour Codes:

    1. Code on Wages (2019): Ensures minimum wages, equal pay for equal work, and timely payment, reducing wage-related exploitation.
    2. Industrial Relations Code (2020): Governs strikes, layoffs, and retrenchments, focusing on maintaining employer–employee harmony under managerial control.
    3. Social Security Code (2020): Extends healthcare, pension, and insurance benefits to gig and platform workers, integrating fragmented welfare laws into one structure.

    Current Trends and Emerging Risks

    1. Extended Working Hours: Post-pandemic, States have increased daily limits and reduced rest periods, heightening fatigue-related risks.
    2. Case Example: Karnataka (2023) made longer shifts permanent, undermining rest and recovery norms critical to accident prevention.
    3. Informalisation: Over 90% of India’s workforce operates informally, with no safety records or accident insurance, leaving families uncompensated.
    4. Weakened Enforcement: Inspections replaced by self-reporting allow companies to evade accountability for safety violations.
    5. Outcome: India remains among the world’s most dangerous industrial economies, with preventable deaths treated as operational costs.

    Institutional and Governance Failures:

    1. Policy Shift: The State’s role has shifted from enforcer to facilitator, prioritising investment over worker welfare.
    2. Diluted Inspections: Labour departments, understaffed and politically pressured, no longer conduct surprise or independent audits.
    3. Token Punishment: Accident inquiries result in minor fines or temporary closures, not criminal prosecutions.
    4. Moral Blindness: Treating workplace deaths as “inevitable” reflects a moral and administrative collapse in valuing human life.

    Way Forward: Restoring Safety as a Fundamental Right

    1. Safety as Right: Workplace safety must be reinstated as a non-negotiable constitutional right, not a regulatory privilege.
    2. Reinforce Inspection: Mandatory and surprise inspections must replace self-certification to ensure compliance.
    3. Criminal Liability: Employers responsible for preventable deaths must face criminal prosecution, not ex gratia settlements.
    4. Economic Logic: Studies confirm that safe workplaces increase productivity and profitability, contradicting industry claims of cost burdens.
    5. Moral Imperative: Until the State enforces accountability, transparency, and legal deterrence, India’s workers will remain collateral casualties of deregulated growth.

     

    [UPSC 2024] Discuss the merits and demerits of the four ‘Labour Codes’ in the context of labour market reforms in India. What has been the progress so far in this regard?

    Linkage: The topic of the erosion of workers’ rights is highly important for the upcoming UPSC Mains, particularly because it connects statutory, economic, and social issues, making it a favorite for analytical questions

     

  • Metal-Organic Frameworks (MOFs) wins Chemistry Nobel Prize, 2025

    Why in the News?

    The 2025 Nobel Prize in Chemistry has been awarded to Richard Robson, Susumu Kitagawa, and Omar Yaghi for pioneering the creation of metal–organic frameworks (MOFs).

    Metal-Organic Frameworks (MOFs) wins Chemistry Nobel Prize, 2025

    What are Metal–Organic Frameworks (MOFs)?

    • Overview: They are crystalline materials composed of metal ions linked by organic molecules, forming a three-dimensional porous network capable of selectively trapping and storing gases, vapours, or liquids.
    • Structure: Metal ions serve as nodes or connectors, while organic ligands (carbon-based linkers) create scaffold-like frameworks with very high surface area and controllable pore size.
    • Porosity: MOFs possess some of the highest porosity among solids, often exceeding 7,000 square metres per gram, enabling the storage of large volumes of gases within minimal material.
    • Flexibility: Organic linkers can be chemically modified, allowing custom design for specific interactions, such as selective gas capture or catalysis.
    • Thermal and Chemical Stability: Advanced MOFs remain stable up to 300–400°C and can withstand diverse chemical environments, suitable for industrial and environmental use.
    • Bonding Principle: Based on coordination chemistry, MOFs combine metal rigidity with organic flexibility, enabling precise control over molecular architecture.
    • Functionality: Their open channels permit easy adsorption and desorption, making MOFs reusable, durable, and efficient for a range of scientific and industrial applications.

    Applications of MOFs:

    • Water Harvesting: Capture moisture from arid air and release it upon heating — enabling portable water generation in desert regions.
    • Carbon Capture: Their selective pores allow efficient CO₂ capture and storage, aiding climate change mitigation.
    • Hydrogen and Methane Storage: Act as solid sponges essential for fuel cells and clean energy systems.
    • Pollutant Filtration: Remove PFAS (Per- and Polyfluoroalkyl Substances), heavy metals, and organic contaminants from water sources.
    • Food Preservation: Absorb ethylene gas emitted by fruits, slowing ripening and extending shelf life.
    • Catalysis and Sensing: Serve as heterogeneous catalysts and chemical sensors for trace-level detection in industrial settings.
    • Clean Energy Systems: Integrated into batteries, fuel cells, and supercapacitors for energy storage due to high conductivity and surface area.

    Scientific Development:

    • Richard Robson (University of Melbourne, 1970s): He pioneered the idea of linking metal atoms and ligands into extended frameworks, though early models were fragile.
    • Susumu Kitagawa (Kyoto University): Built porous coordination polymers, the first to demonstrate that gases could diffuse through molecular cavities—a defining MOF feature.
    • Omar Yaghi (University of California, Berkeley, 1990s): Created robust, heat-resistant MOFs, standardised synthesis techniques, and coined the term “Metal–Organic Framework” in a 1995 Nature paper.
      • Breakthrough Achievement: Yaghi’s team designed copper- and cobalt-based MOFs stable up to 350°C, capable of hosting guest molecules without collapse.

  • Why Indian capital needs to invest domestically?

    Introduction:

    India faces a critical policy challenge — balancing the long-term gains of global trade with the short-term risks of unemployment, stagnant wages, and inequality among vulnerable populations. The existing economic system prioritises private capital accumulation over mass welfare, requiring a realignment of capitalism toward inclusivity and public interest.

    Amid global trade disruptions, tariff wars, and falling external demand, Indian capital must reinvent itself, collaborate closely with the government, and anchor domestic economic stability through investment, innovation, and equitable growth.

    Evolution of Indian Capital and the Need for Reorientation:

    • Protected Growth Era: Historically, Indian capital thrived under state protection before liberalisation, leveraging tariff barriers and inward-looking policies to earn supernormal profits in closed domestic markets.
    • Global Expansion Phase: Liberalisation in the 1990s enabled Indian firms to expand globally, acquiring foreign assets and establishing international linkages. This evolution created a few industrial conglomerates that dominate key sectors.
    • Shift Toward Public-Interest Capitalism: With global trade slowing and protectionism rising, these firms must now redefine their role — from being beneficiaries of state incentives to partners in public-interest growth.
    • Reinvention of Capitalism: Capitalism, as history shows, can adapt and evolve. The moment demands an inclusive capitalism that balances private profit with national development goals.

    Global Trade, Demand, and Economic Vulnerabilities

    • Determinants of Demand Expansion: Economic history identifies three drivers of mass-market expansion, creation of a wage-labour class, productivity gains from industrial production, and rising personal incomes leading to higher demand.
    • Neglect of Aggregate Demand: Growth of aggregate demand is vital for sustaining production and profits, yet most policy frameworks underestimate its role, assuming supply automatically creates demand.
    • Domestic vs. External Demand: In a globalised economy, demand comprises domestic and external components. While early industrial policies relied on internal markets, the post-reform phase emphasised exports.
    • Vulnerability to Global Shocks: Today’s volatile global trade marked by tariffs and supply-chain distortions, has weakened external demand. Thus, strengthening domestic consumption through higher wages, internal investment, and industrial diversification is the pragmatic path forward.

    The Role of Domestic Capital in Stimulating Growth

    1. Reviving Private Investment

      • Stagnation in Private Capex: Despite record corporate profits, private investment has stagnated, with the state driving capital formation through public infrastructure and fiscal stimulus.
      • Rise in Public Investment: Public capex surged from â‚č3.4 lakh crore (FY20) to â‚č10.2 lakh crore (FY25) — a CAGR of 25%, primarily in railways, roads, and communications.
      • Outward vs. Inward Investment: Private capex remains subdued even as outward FDI by Indian firms has grown 12.6% annually (2019–2024), indicating stronger foreign than domestic investment appetite.
      • Strategic Redirection Needed: A strategic reversal is required — redirecting capital toward domestic expansion, capacity building, and industrial diversification.

    1. Ensuring Moderate Wage Growth

      • Profit–Wage Imbalance: The Economic Survey 2024–25 highlighted a growing imbalance — corporate profits at a 15-year high versus stagnant real wages.
      • Falling Real Incomes: Rating agencies project real wage growth to fall from 7% (FY25) to 6.5% (FY26), weakening purchasing power and domestic demand.
      • Labour Market Precarity: Contractualization and weakened collective bargaining in formal sectors have reduced labour’s share of income, intensifying inequality.
      • Need for Wage-Linked Growth: Sustainable growth requires balanced profit–wage dynamics, linking productivity with equitable income distribution to expand internal demand.

    1. Expanding R&D and Innovation:

      • Low R&D Spending: India’s gross expenditure on R&D (GERD) stands at 0.64% of GDP, far below that of the U.S., China, Japan, and South Korea, where private enterprise funds over 70% of total R&D.
      • Weak Private Contribution: In India, the private sector contributes only 36%, with concentration in a few industries, pharmaceuticals, IT, defence, and biotechnology.
      • Innovation as a Structural Imperative: To ensure long-term competitiveness, Indian firms must increase basic and applied research spending, moving beyond short-term, profit-driven innovation cycles.

    Way Forward: Aligning Private Capital with Public Purpose

    • Need for Coordination: The global economic uncertainty necessitates coordinated policy–business action to safeguard growth.
    • Government’s Supportive Role: The government has built a supportive framework through fiscal incentives, simplified regulation, infrastructure development, and credit facilitation. Yet, without active private participation, momentum will stall.
    • Reorientation of Corporate Priorities: Indian capital must realign its priorities:
      • National Responsibility: Treat national economic stability as a collective responsibility, not merely a policy backdrop.
      • Domestic Reinvestment: Reinvest profits domestically to generate employment and strengthen demand.
      • Wage-Led Expansion: Commit to wage-led growth, ensuring equitable income distribution.
      • R&D Commitment: Integrate R&D-driven innovation as a structural pillar of industrial policy.
    • Conclusion: A partnership model — where the state provides the framework and domestic capital drives inclusive, innovation-led expansion — can secure both growth resilience and social legitimacy in the post-globalisation era.

    PYQ Relevance:

    [UPSC 2023] Do you agree that Indian capitalism needs re-orientation towards inclusive and sustainable growth?

     

    Linkage: The issue aligns with GS-III themes: Indian Economy and issues relating to growth, inclusive development, investment models, and effects of liberalisation on the economy.

    It also fits Essay Paper topics like “Capitalism without conscience is a peril to society” or “Economic self-reliance and global interdependence must coexist.”

    The debate concerns how Indian private capital can become a stakeholder in inclusive growth amid protectionism, global trade uncertainty, and sluggish domestic demand.

     

  • Physics Nobel Prize for Quantum Tunneling

    Why in the News?

    The 2025 Nobel Prize in Physics has been awarded to John Clarke, Michel Devoret, and John Martinis for their discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.

    nobel

    Discovery of Macroscopic Quantum Effects:

    • Essence of the Discovery: John Clarke, Michel Devoret, and John Martinis proved that quantum effects—tunnelling and energy quantisation—can occur in macroscopic electrical circuits, not just in atoms or particles.
    • Experiments (UC Berkeley, 1984–85): Demonstrated that superconducting circuits, visible to the naked eye, act as quantum systems when isolated from external disturbances.
    • Observed Phenomena:
      • Macroscopic Quantum Tunnelling: Electric current “jumps” through an insulating barrier even when classical physics predicts no flow.
      • Energy Quantisation: The circuit holds only discrete energy levels, behaving like an artificial atom that exchanges energy in fixed quanta.
    • Scientific Breakthrough: First experimental proof that quantum mechanics governs engineered large-scale systems, forming the foundation of quantum computing.

    The Josephson Junction:

    • Structure: Two superconductors separated by a thin insulating layer, allowing the passage of Cooper pairs paired electrons that move as a single quantum entity.
    • Mechanism: Though insulators block current in classical systems, Cooper pairs tunnel through the barrier, producing a supercurrent without resistance.
    • Key Berkeley Findings:
      • The phase difference across the junction behaved as a quantum variable, showing discrete energy states.
      • Spontaneous tunnelling of current produced measurable voltage, confirming macroscopic quantum tunnelling.
    • Outcome: The Josephson junction became the first laboratory model of macroscopic quantum behaviour and the prototype for superconducting qubits used in today’s quantum computers.

    Significance:

    • Redefined Quantum Boundaries: Established that quantum laws are universal, applying from electrons to circuits of billions of atoms when quantum coherence is preserved.
    • Foundation for Quantum Computing: Provided the conceptual basis for superconducting qubits, now central to Google, IBM, and TIFR quantum processors.
    • Technological Impact: Enabled innovations in quantum sensors, precision metrology, and quantum communication through microwave-to-optical conversion.
    • Philosophical Insight: Resolved the scale question of how large a system can remain quantum,  proving that superconducting isolation preserves coherence even at macroscopic levels.
    • Legacy: Bridged the quantum–classical divide, converting a theoretical boundary into experimentally verified reality, launching the modern quantum technology era.

  • The Nobel laurates’ work has redefined the immune system itself

    Introduction

    For decades, the immune system was viewed as a binary apparatus either attacking foreign invaders or remaining silent toward the body’s own cells. This year’s Nobel laureates, Mary Brunkow, Fred Ramsdell, and Shimon Sakaguchi, dismantled that simplistic view by uncovering the critical role of regulatory T-cells (Tregs) and the FOXP3 gene in maintaining self-tolerance. Their findings fundamentally redefined how scientists perceive immune regulation and opened the path for precision immunotherapy — one of modern medicine’s most promising frontiers.

    The Science of Self-Tolerance: Why It’s in the News

    The Nobel Committee’s recognition of research on regulatory T-cells (Tregs) and FOXP3 marks a watershed moment in immunology. For the first time, the prize acknowledges discoveries that explain how the immune system prevents itself from attacking the body. The work explains why autoimmune disorders like Type 1 diabetes, rheumatoid arthritis, and lupus occur when this “self-check” mechanism fails. It also connects molecular immunology to emerging therapies for cancer and transplantation. This is a landmark shift from viewing immunity as mere “defence” to seeing it as a balance of activation and restraint, a concept that has redefined global biomedical research.

    How the Nobel-winning Discovery Unfolded

    1. Early Understanding: In the 1990s, immunologists believed that self-reactive T-cells were deleted during their maturation. However, this could not explain why some autoreactive T-cells still existed in healthy people.
    2. Sakaguchi’s Breakthrough (1995): Identified a subset of CD4âș T-cells whose removal in mice led to multiple autoimmune disorders. Restoring them prevented disease — proving they act as regulators of immune overreaction.
    3. Discovery of FOXP3 Gene: Brunkow and Ramsdell, working in an industry lab (Celltech Chiroscience), traced severe autoimmune disease in male “scurfy” mice to a gene mutation on the X chromosome. They named it FOXP3.
    4. Human Correlation: Soon, mutations in FOXP3 were linked to lethal autoimmune syndromes in boys, confirming its pivotal role in human immune regulation.

    How These Discoveries Transformed Immunology

    • Redefining the Immune System: The immune system is now seen not as an on/off mechanism but as a dynamic ecosystem that balances activation (attack) with restraint (tolerance).
    • New Therapeutic Frontiers:
      1. Autoimmune Diseases: Efforts are underway to expand or stabilise Tregs to curb harmful immune activation without broad immunosuppression.
      2. Transplant Medicine: Infusion of engineered Tregs improves graft acceptance and reduces rejection rates.
      3. Cancer Research: Selective depletion or reprogramming of tumour-associated Tregs enhances anti-tumour immunity without triggering autoimmunity.

    From Lab to Life: The Translational Challenge

    1. Incremental Progress: Immunologists warn against overestimating breakthroughs. The immune system has multiple overlapping control layers, making clinical translation slow.
    2. High Cost Barrier: Cell-based therapies remain expensive, leading to inequitable access between high- and low-income populations.
    3. Ethical and Policy Dilemmas: Who gets access first? How do we regulate genetic manipulation or Treg engineering? These questions highlight the intersection of science, ethics, and public policy.

    Private Sector and Scientific Innovation

    1. Industrial Discovery: The fact that Brunkow and Ramsdell made their discoveries in an industry setting (Celltech Chiroscience) underscores the potential of private-sector-led innovation in fundamental science.
    2. Public–Private Synergy: It reinforces how collaborations between academic research and biotech industry can accelerate discovery and application, a model India can emulate in its biotechnology policy framework.

    Broader Implications for India and Global Health

    1. Indian Relevance: India’s growing burden of autoimmune diseases (such as lupus, celiac, and thyroiditis) highlights the need for indigenous immunogenetic research.
    2. Policy Perspective: Translating such research into affordable therapies aligns with National Biotechnology Development Strategy and Ayushman Bharat’s preventive healthcare goals.
    3. Global Impact: These discoveries open a new era of personalised immunotherapy, integrating molecular biology, bioethics, and equitable access.

    Conclusion

    The 2025 Nobel Prize reminds the world that progress in science often lies not in creating new weapons against disease but in understanding balance, the balance within nature and within ourselves. The discovery of Tregs and FOXP3 has rewritten textbooks, inspired therapies, and expanded our conception of what “self” and “immunity” truly mean. For policymakers and scientists alike, it represents the future, a fusion of molecular precision, ethical responsibility, and social justice.

    PYQ Relevance

    [UPSC 2021] The Nobel Prize in Physics of 2014 was jointly awarded to Akasaki, Amano and Nakamura for the invention of Blue LEDs in the 1990s. How has this invention impacted the everyday life of human beings?

    Linkage: Both the 2014 Nobel for Blue LEDs and the 2025 Nobel for Treg–FOXP3 discovery represent paradigm shifts where scientific breakthroughs moved from lab theory to real-world transformation — the former revolutionised energy efficiency, while the latter is redefining human health and immune regulation.

  • SC to examine Constitutional Validity of Securities Transaction Tax (STT)

    Why in the News?

    The Supreme Court of India has agreed to examine a petition challenging the constitutional validity of the Securities Transaction Tax (STT) imposed under the Finance Act, 2004.

    Legal Context of this Case:

    Petitioner: Aseem Juneja – contends that STT violates fundamental and economic rights.

    Bench: Headed by Justice J.B. Pardiwala; formal notice issued to Union Ministry of Finance.

    • The plea invokes Article 265 — “No tax shall be levied or collected except by authority of law.”
    • The Court will assess reasonableness, equity, and proportionality in transaction-based taxation.
    • A ruling against STT may impact â‚č30,000-crore annual revenue and require redesign of securities taxation.

    SC to examine Constitutional Validity of Securities Transaction Tax (STT)

    What is the Securities Transaction Tax (STT)?

    • About: A direct tax levied on purchase and sale of securities through recognised stock exchanges.
    • Introduction: Under the Finance Act, 2004, to ensure transparency and curb tax evasion in capital markets.
    • Objective: Replace complex capital-gains tracking with a small, upfront levy to counter under-reporting and increase tax buoyancy.
    • Administered by: Central Board of Direct Taxes (CBDT), Ministry of Finance.
    • Scope: Applies to-
      1. Equity shares of listed companies
      2. Derivatives (futures & options)
      3. Equity-oriented mutual funds and ETFs.
    • Purpose:
      • Simplify tax collection from capital market participants.
      • Create a traceable, automated tax mechanism.
      • Generate steady revenue while discouraging speculative trading.
    • Nature: A transaction-based tax (TBT) collected automatically at the time of trade, irrespective of overall profit or loss.
    • Distinctive features:
        • Applies even on loss-making trades payable merely for conducting a transaction.
        • Non-refundable and non-adjustable, unlike TDS.
        • Raises transaction costs for high-frequency traders.
    • Imposition of STT:
      • Mode of collection: Automatically deducted by stock exchanges on every taxable trade and deposited into the government account; Ensures near-universal compliance and minimal evasion.
      • Rate & coverage: Varies across instruments and between buy/sell transactions; Periodically revised through Union Budgets.

    Key Grounds of Challenge:

    • Violation of Fundamental Rights:
      1. Article 14 (Equality): Unequal treatment; tax imposed irrespective of gain or loss.
      2. Article 19(1)(g) (Right to Trade): Penalises the act of trading itself.
      3. Article 21 (Livelihood & Dignity): Non-refundable levy burdens small traders.
    • Double Taxation: Traders already pay Capital Gains Tax on profits; STT adds a second layer on the same transaction.
    • Arbitrariness / Lack of Proportionality: Taxing even unprofitable transactions violates the principle of reasonable classification and fiscal fairness.
    • No Refund or Adjustment Mechanism: Absence of provision similar to TDS refunds; creates permanent loss even when income is negative.
    • Changed Circumstances: With digital audit trails, PAN-linked demat accounts, and near-complete transparency, the original rationale (to curb evasion) may no longer hold.
