• Science Nobel: The Nobel Prize in Physiology or Medicine was awarded to Shimon Sakaguchi, Mary Brunkow and Frederick Ramsdell for the discovery of regulatory T cells and the FOXP3 gene.
• Wildlife: Project TOTR (Tigers Outside Tiger Reserves) was launched with Rs 88.7 crore for AI-based monitoring in 80 forest divisions across 17 tiger-range states.
• Social: The ILO State of Social Justice 2025 report found that the top 1 per cent control 38 per cent of global wealth and the gender wage gap will take 50 to 100 years to close at the current pace.
• Economy: India's total trade reached $1.73 trillion in the previous year, with services exports at a record $387.5 billion, according to the NITI Aayog Trade Watch report.
• Judiciary: A member of the PM's Economic Advisory Council publicly called the judiciary India's "single biggest hurdle to progress." A substantial counterargument was laid out in the editorial space.

The 2025 Nobel Prize in Physiology or Medicine was awarded jointly to Shimon Sakaguchi (Osaka University, Japan), Mary E. Brunkow (Institute for Systems Biology, USA) and Frederick J. Ramsdell (Sonoma Biotherapeutics, USA).

• Discovery: peripheral immune tolerance is maintained by a specialised subset of T cells called regulatory T cells (Tregs). Tregs suppress excessive immune responses and prevent the immune system from attacking the body's own tissues.
• FOXP3 gene: the master control gene that determines whether a T cell becomes a Treg. Brunkow and Ramsdell identified FOXP3. Sakaguchi showed that Tregs expressing FOXP3 are essential for self-tolerance.
• IPEX syndrome: in humans, the absence of functional FOXP3 causes Immune dysregulation, Polyendocrinopathy, Enteropathy, X-linked syndrome, a severe autoimmune condition that is usually fatal in infancy.
• Clinical applications: manipulating Tregs is now a treatment strategy in cancer immunotherapy (suppressing Tregs helps the immune system attack tumours), autoimmune diseases (enhancing Tregs prevents self-attack) and organ transplantation (enhancing Tregs prevents rejection).
• Prize amount: approximately SEK 11 million.

GS area: Environment (Wildlife Conservation)

The government launched Project TOTR (Tigers Outside Tiger Reserves) for 2025-2028 with a total outlay of Rs 88.7 crore.

• Coordinating agency: National Tiger Conservation Authority (NTCA). Implementation is through state forest departments.
• Coverage: 80 forest divisions across 17 tiger-range states. Focus states include Madhya Pradesh, Maharashtra, Karnataka, Uttarakhand, Assam, Kerala, Tamil Nadu, West Bengal and Arunachal Pradesh.
• Technology components: AI-based early warning systems and camera trap networks; GPS-enabled patrolling software; rapid response teams with local youth as Bagh Mitras.
• Associated launches:
  • Project Dolphin Phase II: river dolphin conservation.
  • Project Sloth Bear: first national framework specifically for sloth bears.
  • Project Gharial: conservation programme for the Critically Endangered gharial (Gavialis gangeticus).
  • Centre of Excellence for Human-Wildlife Conflict Management (CoE-HWC) at the Salim Ali Centre for Ornithology and Natural History (SACON) in Coimbatore.

Tigers are not confined to their named reserves. They disperse through corridors connecting reserves. TOTR addresses the governance gap where corridor-dwelling tigers fall outside the NTCA's core monitoring framework.

GS area: Society, International Organisations

The International Labour Organisation released its State of Social Justice 2025 report.

• Poverty reduction: extreme poverty fell from 39 per cent in 1995 to 10 per cent in 2025. Working poverty fell from 28 to 7 per cent over the same period.
• Child labour: the number of children aged 5 to 14 in child labour fell from 250 million to 106 million.
• Social protection coverage: over 50 per cent of the global population now has some form of social protection.
• Inequality persistence: the top 1 per cent control 20 per cent of global income and 38 per cent of global wealth.
• Gender wage gap: women earn 78 per cent of what men earn. At the current pace, closing this gap will take 50 to 100 years.
• Birth determinism: 55 per cent of income inequality is explained by the country of birth, a fact that exposes the limits of individual effort in a globalised economy.
• India: multidimensional poverty fell from 29 per cent in 2013-14 to 11 per cent in 2022-23; female labour force participation reached 37 per cent (PLFS 2024-25); 80 per cent of the workforce operates outside formal contracts.
• Key India schemes referenced: PM-KISAN, Ayushman Bharat, e-Shram, PMKVY, JAM Trinity (Jan Dhan-Aadhaar-Mobile).

GS area: Economy (Trade, International Relations)

The NITI Aayog's Trade Watch Quarterly Report for Q4 FY2024-25 released.

• Total trade: $1.73 trillion, a 6 per cent increase year-on-year.
• Exports: $823 billion; imports: $908 billion.
• Services exports: $387.5 billion, a record high. North America was the top destination at 25 per cent of exports, growing 25 per cent year-on-year.
• Import shifts: the UAE overtook Russia as India's second-largest supplier. Chinese imports surged.
• Significance: India's total trade crossing $1.7 trillion signals its entry into the upper tier of global trade economies. Services exports exceeding $380 billion demonstrate the growing weight of IT, financial services and professional services.

GS area: Polity (Judiciary), Ethics

A parliamentary discussion on passive euthanasia regulations prompted analysis of existing law and proposed reforms.

• Aruna Shanbaug v. Union of India (2011): the Supreme Court recognised passive euthanasia under strict judicial supervision for the first time.
• Common Cause v. Union of India (2018): the Supreme Court recognised the right to die with dignity as part of Article 21. Advance medical directives (living wills) were declared legally valid.
• 2023 modification: the Court simplified execution of living wills, a Judicial Magistrate First Class now attests the document; a primary medical board of three senior doctors reviews it; a secondary board involving the Chief Medical Officer also reviews; a seven-day cooling-off period applies.
• Article 21: the right to life and personal liberty. The Court extended its scope to include the right to a dignified death.
• Proposed reforms discussed: an Aadhaar-linked national portal for advance directives; hospital ethics committees empowered to decide within 48 hours without referring to magistrates.

GS area: Polity (Judiciary, Governance)

A member of the Prime Minister's Economic Advisory Council stated that the judiciary is the "single biggest hurdle to India's progress." The editorial debate that followed:

• Section 12A, Commercial Courts Act 2015: mandated pre-suit mediation for commercial disputes. This provision is poorly designed and rarely used, the criticism of delay in commercial justice partly reflects legislative failure, not judicial failure.
• Government as the largest litigant: the government at all levels is responsible for the largest share of pending litigation in India's courts. Reducing government litigation is a more controllable lever than restructuring the judiciary.
• Structural constraints: Indian judges hear 50 to 100 cases per day. Courts are chronically underfunded. The judge-to-population ratio in India (about 21 per million) is far below the global average.

• UNESCO Director-General: Khaled El-Enany of Egypt was elected as the new Director-General of UNESCO for 2025-2029 with 55 votes in the 58-member Executive Board.
• Black Sea geography: 4,36,000 square kilometres; bordered by Turkey, Bulgaria, Romania, Ukraine, Russia and Georgia. Connected to the Mediterranean via the Bosporus Strait, Sea of Marmara and Dardanelles Strait. The world's largest meromictic basin (anoxic lower layers due to no mixing with fresh surface water).
• Male Mahadeshwara Wildlife Sanctuary: Chamarajanagara district, Karnataka. Declared in 2013. At the intersection of Western and Eastern Ghats. Contiguous with the Biligiri Rangaswamy Tiger Reserve, Sathyamangalam Tiger Reserve and Cauvery Wildlife Sanctuary.
