• Nobel Chemistry: Omar Yaghi, Susumu Kitagawa and Richard Robson win for Metal-Organic Frameworks, ultra-porous materials with applications in carbon capture, water harvesting and drug delivery.
• Labour: NITI Aayog released a roadmap for AI in inclusive development. India has 490 million informal workers contributing about 50 per cent of GDP.
• Agriculture: e-NAM expanded its tradable commodities list by nine, bringing the total to 247.
• International Solar: The 8th ISA General Assembly is scheduled for 27-30 October in New Delhi. India's solar capacity now exceeds 110 GW.
• Defence: The AMRAAM air-to-air missile sale from the United States to Pakistan entered the news cycle. India's domestic ASTRA BVR missile provides a comparable capability.

The 2025 Nobel Prize in Chemistry was awarded to Susumu Kitagawa (Kyoto University, Japan), Richard Robson (University of Melbourne, Australia) and Omar Yaghi (University of California, Berkeley, USA/Jordan).

• Discovery: Metal-Organic Frameworks (MOFs), crystalline, three-dimensional porous structures built by linking metal ions with organic molecules.
• Pioneering contributions: Robson (1970s-80s) conceptualised porous molecular networks; Kitagawa (1990s) proved that MOFs could absorb and release gases with exceptional flexibility; Yaghi (2000s) stabilised the frameworks and developed "reticular chemistry", a systematic approach to designing MOFs atom by atom.
• Extraordinary porosity: one gram of a MOF can have a surface area equivalent to several football fields.
• Applications: CO₂ capture from industrial exhausts; water extraction from arid air (a desert water-harvesting technology); hydrogen and methane storage for fuel cells; removal of PFAS chemicals and heavy metals from water; targeted drug delivery in pharmaceutical applications.
• Prize amount: approximately SEK 11 million.

NITI Aayog released a roadmap titled "AI for Inclusive Societal Development," addressing how artificial intelligence can reach informal workers.

• Scale of informality: 490 million informal workers; they contribute approximately 50 per cent of India's GDP.
• Conditions: 80 per cent of rural workers lack formal contracts; women make up 55 per cent of informal labour; 75 per cent of informal workers earn below Rs 10,000 per month; only 12 per cent access organised markets; 70 per cent lack digital literacy.
• Platform workers: 7.5 million platform workers (2022 estimate) with no labour law protections.
• AI's projected role: PwC projects a $957 billion GDP boost from AI-driven productivity by 2035.
• Key recommendation: a "Digital ShramSetu Mission", an AI-integrated platform combining social security registration, skilling and livelihood access for informal workers.
• Labour and Employment Policy Evaluation Index (LEPEI): a proposed metric to track outcomes across schemes.

GS area: Agriculture (Agricultural Markets)

The National Agriculture Market (e-NAM) added nine new commodities, bringing its total tradable commodities to 247.

• e-NAM launch: 14 April 2016.
• Purpose: connect state-level APMC mandis into a unified national market via a common online trading platform.
• New additions: Green Tea, Tea, Ashwagandha Dry Roots, Mustard Oil, Lavender Oil, Mentha Oil, Virgin Olive Oil, Lavender Dried Flower and Broken Rice.
• Significance of new additions: the inclusion of Ashwagandha (an ayurvedic herb with global export demand) and essential oils (Lavender, Mentha) reflects the push to formalise high-value specialty crop markets.

GS area: International Relations (Multilateral, Energy)

The 8th Assembly of the International Solar Alliance is scheduled for 27 to 30 October 2025 at Bharat Mandapam, New Delhi.

• ISA origin: co-founded by India and France at COP21 in Paris in 2015.
• HQ: Gurugram, Haryana, the first international organisation headquartered in India.
• Members: 124 member and signatory countries; more than 90 full members.
• Goals: mobilise $1 trillion in solar investments by 2030; energy access for 1 billion people; 1,000 GW of solar capacity globally.
• Africa Solar Facility: based in Ahmedabad. Target: leverage $200 million by 2026 to mobilise $2 to 4 billion for African solar projects.
• STAR-C: Solar Technology and Application Resource Centres, technical assistance hubs established in member countries.
• India's solar progress: 110.9 GW installed capacity; ranked third globally. Record 23.83 GW added in 2024-25.

The United States cleared a sale of AIM-120 AMRAAM air-to-air missiles to Pakistan.

• AMRAAM full name: Advanced Medium-Range Air-to-Air Missile.
• Type: beyond-visual-range, radar-guided, fire-and-forget.
• Developer: US Air Force and Raytheon; entered service in the 1980s.
• Range: up to 160 kilometres in the latest C8 and D3 variants.
• Speed: Mach 4; compatible with F-15, F-16, F-35, Eurofighter Typhoon and Gripen.
• India's counterpart: the ASTRA BVR missile, developed by DRDO. Range 80 to 110 kilometres; speed Mach 4-plus; carried by the Su-30 MKI and the Tejas.
• Strategic context: following the May 2025 India-Pakistan air standoff, any enhancement of Pakistan's air-to-air missile inventory has direct strategic implications for India's air defence planning.

• Designation: India's largest greenfield airport project.
• Phase 1 capacity: 20 million passengers per year, expandable to 90 million.
• Cargo capacity: 0.5 million metric tonnes, expandable to 3.25 million.
• Runways: two parallel Code F runways of 3,700 metres each.

• Wheat MSP 2025-26: Rs 2,585 per quintal. Increase of Rs 160 per quintal or 6.6 per cent. CACP-projected A2+FL cost: Rs 1,239 per quintal. The MSP is 109 per cent above the A2+FL cost. CACP (Commission for Agricultural Costs and Prices) recommends MSPs; procurement is by FCI.
• Atacama Desert, rare bloom: Unusual winter rains triggered a rare "Desierto Florido" (Flowering Desert) bloom in northern Chile. The Atacama is the driest non-polar desert globally with about 2 mm of annual rainfall.
• Gender-Affirming Care: WHO classifies gender-affirming care as medically necessary. The Transgender Persons (Protection of Rights) Act, 2019 is India's legal framework. More than 31 per cent of transgender persons in India have attempted suicide, according to a 2024 health survey.
