💧 WATER CONSERVATION PRIORITISED UNDER MGNREGA

Theme: Government Policies & Interventions | Rural Development | Sustainable Water Management.

📰 Context

The Central Government has amended the Schedule of the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA), 2005, to prioritise water conservation and harvesting works in rural areas.
The Ministry of Rural Development (MoRD) notified this policy change on September 23, 2025.

⚙️ Key Highlights of the Amendment

🔹 New Focus: Rural water assets — check dams, percolation tanks, ponds, and recharge wells.
🔹 Minimum Share: 60% of MGNREGA works must now relate to agriculture and water conservation.
🔹 Groundwater Stress Priority: Over-exploited and semi-critical blocks will receive preferential funding.
🔹 Integrated Implementation: Linked with the Jal Shakti Abhiyan, Atal Bhujal Yojana, and PM Krishi Sinchai Yojana.

💦 Objectives

✅ Strengthen water resilience and sustainable rural livelihoods.
✅ Reduce dependence on monsoons and enhance farm productivity.
✅ Create durable community assets to tackle drought and climate stress.
✅ Promote convergence between environmental regeneration and employment.

🧭 UPSC Mains Relevance

GS Paper 2: Welfare schemes for vulnerable sections; issues in implementation.

GS Paper 3: Conservation of natural resources, Environmental impact and rural development synergy, Climate change adaptation through water management.

🎯 UPSC Prelims Pointers

• Implementing Ministry: Ministry of Rural Development (MoRD).

• Legal Backing: Section 16, Schedule I of the MGNREGA, 2005.

2025 NOBEL PRIZE IN MEDICINE

Theme: Science & Technology | Biotechnology | Human Physiology

🧠 Context

The 2025 Nobel Prize in Physiology or Medicine was awarded to Mary E. B. Runkow (USA), Frederick Ramsdell (USA), and Shimon Sakaguchi (Japan) for discovering Regulatory T Cells (Tregs) — the “police cells” that prevent the immune system from attacking the body’s own tissues.

⚙️ Key Discovery

🔹 Regulatory T Cells (Tregs): A subset of white blood cells that maintain immune tolerance — preventing the immune system from damaging self-tissues.
🔹 Gene Identified: FOXP3 — the master gene that controls Treg development.
🔹 Function: Tregs suppress overactive immune responses that can cause autoimmune diseases such as type-1 diabetes, rheumatoid arthritis, multiple sclerosis, and lupus.
🔹 Mechanism: They act as “brakes” of the immune system — balancing attack and restraint.

🔍 UPSC Mains Relevance (GS Paper 3)

• Science & Technology: Developments in biotechnology & health research.

• Health Sector: Understanding autoimmune disorders & immune regulation.

• Applications: Future scope in immunotherapy, organ transplantation, and cancer treatment.

🎯 UPSC Prelims Relevance

Possible MCQ Angles:
1️⃣ 2025 Nobel Prize awarded for discovery of Regulatory T Cells (Tregs).
2️⃣ FOXP3 gene is associated with development of immune tolerance.
3️⃣ Function of Tregs → prevent immune system from attacking self-tissues.
4️⃣ Shimon Sakaguchi first identified Tregs in the 1990s.
5️⃣ Autoimmune diseases arise when immune tolerance fails.

💡 Significance

✅ Deeper understanding of immune balance → better treatment of autoimmune diseases.
✅ Foundation for next-generation cell-based immunotherapies.
✅ May lead to customised immune modulation in cancer & organ transplant medicine.
✅ Reinforces India’s focus on immunology under National Biotech Development Strategy 2025.

⚖️ Ethical Dimensions (GS4 Link)

• Balancing medical innovation with safety & equity.

• Ethical trials in gene therapy & immune modulation.

• Access to immunotherapies in low-income nations.

🧩 Conclusion

This Nobel-winning discovery unravels one of biology’s deepest puzzles — how the immune system knows when to fight and when to stand down. It opens the path to curing autoimmune diseases through precision immunology.
