Current members (11): Brazil, China, Egypt, Ethiopia, India, Indonesia, Iran, Russia, Saudi Arabia, South Africa, UAE. Scale: members together account for 49.5% of world population, 40% of global GDP and 26% of global trade. Partner Country category: 10 states admitted in 2025 — Belarus, Bolivia, Cuba, Kazakhstan, Malaysia, Nigeria, Thailand, Uganda, Uzbekistan, Vietnam. India's 2026 theme: "Building for Resilience, Innovation, Cooperation and Sustainability." 18th Summit: New Delhi, 12–13 September 2026; India's Chairship began 1 January 2026 and spanned over 350 meetings across 25 cities. Lineage — from a four-country dialogue to an 11-member bloc 2009: first BRIC Summit at Yekaterinburg, prompted by the 2008 financial crisis and calls for a more representative IMF/World Bank. 2011: South Africa admitted, forming BRICS. January 2024: Egypt, Ethiopia, Iran, Saudi Arabia and the UAE became full members. January 2025: Indonesia joined as the 11th member; a separate Partner Country track was created the same year. India has chaired the grouping before in 2012 (New Delhi, Delhi Declaration), 2016 (Goa) and 2021 (virtual, BRICS@15) — this is its fourth Chairship.

Why it matters BRICS functions as a platform for emerging economies to coordinate positions on global economic governance, including reform of the IMF, World Bank and WTO, and to advance South-South cooperation across development, finance and technology. Outcomes flagged under India's 2026 Chairship New cooperation platforms in agriculture (Centres of Excellence on Agro-Ecology, Digital Agriculture Network, AGRIN), health (Healthy Lifestyle Mission, Mental Health Training Hub with NIMHANS as coordinator) and MSMEs/startups (Cooperation Portal, Incubator Network, Startup Innovation Fund). Economic-architecture items: a Global Value Chains Action Plan 2026–2030, in-principle approval of a Customs mutual-assistance agreement, a Logistics Supply-Chain Cooperation Framework and an MoU on standardisation. Energy and urban items: Guiding Principles on Energy Storage and Smart Grids, and a BRICS Urban Mobility Hub with voluntary principles for climate-resilient urban infrastructure. The critical view Most outcomes listed are voluntary, consensus-based platforms rather than binding commitments, and BRICS continues to include members with sharply divergent positions on trade, sanctions and security — a structural constraint on converting its economic weight into unified diplomatic action. ✎ Mains Practice Question "BRICS has grown in scale but its ability to convert economic weight into coordinated global influence remains limited." Examine this statement with reference to the grouping's expansion since 2006 and India's role as a recurring Chair. 15 marks · 250 words EconomyGeneral Studies Paper III 02 Pradhan Mantri Matsya Sampada Yojana Completes Six Years GS-III · Economy — Agriculture & Allied SectorsPrelims + MainsPIB Delhi · Ministry of Fisheries, Animal Husbandry and Dairying The Pradhan Mantri Matsya Sampada Yojana, launched in 2020 to modernise India's fisheries value chain, completed six years on 10 September 2026 with a record ₹2,500 crore allocation for 2026–27. ▤ Scheme at a Glance Launched: 2020–21, building on the earlier Blue Revolution scheme. Total outlay: ₹20,750 crore; BE 2026–27 allocation ₹2,500 crore. Nodal Ministry: Ministry of Fisheries, Animal Husbandry and Dairying (Department of Fisheries). Structure: umbrella scheme with a Central Sector (CS) component and a Centrally Sponsored Scheme (CSS) component. Key sub-scheme: Pradhan Mantri Matsya Kisan Samridhi Sah-Yojana (PM-MKSSY), 2023-24 to 2026-27, outlay ₹6,000 crore, for formalisation, insurance and institutional finance. Coverage: approved projects worth ₹21,394.88 crore (Central share ₹9,510.89 crore) as of 11 August 2026, across States, UTs and implementing agencies. Stated targets: the Government cites 58 lakh direct and indirect jobs created in fisheries and aquaculture-related activities (government figure). Lineage PMMSY builds on the Blue Revolution scheme, extending it from a production-focused programme into a full value-chain intervention covering infrastructure, exports, digital governance and fisher welfare.

Infrastructure and digital push Cold-chain and marketing infrastructure worth ₹2,797 crore approved, including 775 cold storages/ice plants, 24 wholesale fish markets, 117 retail fish markets and over 28,000 fish transportation units. 2,195 Fish Farmers Producer Organisations supported (₹544.86 crore) to strengthen collective bargaining power. 100 coastal villages identified as Climate Resilient Coastal Fishermen Villages, at ₹200 lakh per village under the Central Sector component. The National Fisheries Digital Platform, launched under PM-MKSSY in September 2024, had recorded over 37 lakh registrations as of 8 September 2026, enabling access to credit, insurance and traceability. Institutions & terms to know Recirculatory Aquaculture System (RAS): filters and recirculates water for intensive fish farming with minimal land and water use. Bio-floc technology: recycles nutrients using beneficial microbes; needs little water exchange, sometimes called "green soup" aquaculture. National Fisheries Development Board (NFDB): institution strengthened under the CS component of PMMSY. The critical view The government's job and income figures are self-reported targets rather than independently verified outcomes, and the fisheries sector still faces recurring concerns over deep-sea fishing regulation, overexploitation of coastal stocks and the livelihood security of small and traditional fishers who may not fully access scheme benefits designed around formal registration and institutional credit. ✎ Mains Practice Question Discuss the role of the Pradhan Mantri Matsya Sampada Yojana in transforming India's fisheries value chain. What structural challenges remain in ensuring the scheme's benefits reach small and traditional fishers? 15 marks · 250 words 03 Government Amends E-Commerce Rules to Strengthen Consumer Protection GS-III · Economy — E-Commerce & Consumer ProtectionPrelims + MainsPIB Delhi · Department of Consumer Affairs, Ministry of Consumer Affairs, Food & Public Distribution The Department of Consumer Affairs has notified the Consumer Protection (E-Commerce) (Amendment) Rules, 2026, tightening disclosure and grievance-redressal norms for e-commerce entities, effective from 1 January 2027. ▤ Scheme at a Glance Instrument: Consumer Protection (E-Commerce) (Amendment) Rules, 2026, amending the E-Commerce Rules, 2020. Statutory basis: Consumer Protection Act, 2019. Nodal authority: Department of Consumer Affairs. Effective date: 1 January 2027. Grievance context: the National Consumer Helpline received 17,71,622 grievances in 2025, of which about 29% (5,11,196) related to e-commerce. Lineage — from the 2020 Rules to the 2026 Amendment The E-Commerce Rules, 2020 first created a regulatory framework for unfair trade practices in online retail. The 2026 amendment responds to gaps exposed by newer business models — search manipulation, undisclosed sponsored listings and dark patterns — that the original Rules did not squarely address. Figure 5 — From the 2020 Rules to the 2026 Amendment ConsumerProtection Act, 2019(parent statute)E-Commerce Rules,2020(base framework)Amendment Rules,2026search, dark patterns,price history, NCH tie-upIn force from 1 January 2027 The 2026 amendment adds new disclosure and grievance obligations on top of the 2020 base framework, effective 1 January 2027. Key changes Search results: entities barred from manipulating search results in ways that mislead users or distort relevance to the query entered. Sponsored listings: must carry clear, prominent disclosure. Price reductions: both the reduced and the "prior price" (lowest price in the preceding 30 days) must be shown. Dark patterns: compliance with the 2023 Dark Patterns Guidelines, a yearly self-audit, and a displayed compliance certificate. Disclosures: best-before dates, return/refund/warranty/delivery/payment terms, and importer/country-of-origin details for imported goods. Consent and fees: consumer data cannot be used for specified purposes without express consent; bundled fees for unrelated services are barred, subject to a loyalty/membership exception. Grievance redressal: every e-commerce entity must become a partner in the National Consumer Helpline's convergence process, and share complaint copies with complainants. Institutions & terms to know National Consumer Helpline (NCH): the central grievance-aggregation mechanism the Rules now formally integrate e-commerce entities into. Dark Patterns Guidelines, 2023: issued under the Central Consumer Protection Authority framework; the 2026 Rules now make yearly self-audit against them mandatory for e-commerce entities. The critical view The Rules rely substantially on self-audits and self-certification for dark-pattern compliance rather than independent verification, and a 15-month lead time before the January 2027 commencement gives platforms room to adapt disclosures without necessarily changing underlying design practices; enforcement capacity at the Central Consumer Protection Authority will determine how effective the changes prove in practice. ✎ Mains Practice Question Examine the key changes introduced by the Consumer Protection (E-Commerce) (Amendment) Rules, 2026. How far do they address the problem of "dark patterns" and opaque pricing in online retail?

ImportantOpinionGS-II · Education & Human Resource DevelopmentMains-orientedThe Hindu · Parley A New York City moratorium on generative AI in public schools up to Class 8 has revived a debate that India is yet to settle through policy — should young children be kept away from AI tools in the classroom, or taught to use them under guardrails? ◈ Background & Context New York City's mayor announced a one-year moratorium on most generative AI tools for public school students up to Class 8, for the 2026–27 academic year, on the reasoning that young children need human connection and independent problem-solving rather than algorithmic assistance. India's Central and State governments are separately piloting AI tools in government schools, partly to address teacher shortages in rural areas. India does not yet have a settled, binding policy position on generative AI use by younger school students. The case against a blanket ban Children today are already AI-literate through everyday use of search engines, email and games, so excluding AI from the classroom does not remove their exposure to it. A rules-based approach — think first, write it, then verify with AI, rather than asking AI for the answer directly — can preserve the "struggle" of learning while still using the tool. AI-enabled apps can personalise instruction, for example flagging mispronounced words for a struggling reader or suggesting a more visual way to teach a concept a student has not grasped. The case for caution and restriction Over-reliance risks weakening independent thinking during the primary and elementary years, when cognitive and neuroplastic development is most active. Educationists describe a "liminal space" — the productive struggle between not knowing and understanding — as essential to learning; letting AI short-circuit that struggle removes a formative part of education. AI tools can also carry embedded bias: a reading-fluency app was reported to mark correctly-read words as errors when spoken in Indian or other Asian accents, illustrating a real limitation of algorithmic assessment. A one-year moratorium alone may be too short a window to design proper guardrails around classroom AI use. Where both positions converge Neither side in the debate favours AI replacing teachers. The shared position is that AI should extend a teacher's capacity — for lesson preparation, differentiated instruction and administrative tasks — while the human relationship between teacher and student remains central, particularly at the primary level. Institutions & terms to know AI hallucination: the tendency of generative AI to produce plausible-sounding but factually incorrect output — cited as a reason teachers must verify AI-generated teaching material. India's AI-in-education pilots: government-school and rural pilot projects aimed at using AI to supplement teacher shortages, referenced as the live Indian policy context. ✎ Mains Practice Question "AI should extend the teacher, not replace her." Discuss this view in the context of generative AI use by young students, and outline the safeguards India's school education policy should consider. 10 marks · 150 words 02 Twenty-Five Years On, America's Response to 9/11 and Its Continuing Costs Core TopicOpinionGS-II · IR — International Events, Terrorism & Security PolicyPrelims + MainsThe Hindu · Op-Ed Twenty-five years after the 11 September 2001 attacks, a former U.S. Senate staffer argues that Washington's policy response — two prolonged wars, expanded surveillance powers and a permanent security apparatus — did more lasting damage to the United States than the attacks themselves. ◈ Background & Context The 11 September 2001 attacks killed 2,977 people and were quickly attributed to Al Qaeda. The article distinguishes between the U.S. response in Afghanistan — where military action followed the attacks with few realistic alternatives — and the invasion of Iraq, which it characterises as a war of choice unrelated to the attackers. The U.S. subsequently expanded state surveillance and detention powers, created the Department of Homeland Security and Immigration and Customs Enforcement (ICE), and adopted expanded interrogation practices for military detainees. The piece places the more recent U.S. military action against Iran in the same lineage of open-ended, poorly defined interventions launched in the post-9/11 security posture. Costs identified Legal and institutional: expanded surveillance and detention authority, and new security institutions that reshaped domestic policing and immigration enforcement. Human and financial: two decades-long wars costing trillions of dollars, with the great majority of casualties being Iraqi and Afghan civilians, and, per the article, more American service members killed in these wars than were killed in the original attacks. Opportunity cost: resources devoted to prolonged wars are contrasted with other risks — disease, climate change, and other threats — that the piece argues received comparatively less sustained attention and funding. Social cost: the brief post-attack sense of national unity is contrasted with today's more polarised political climate, and with continuing profiling of people perceived as being from South Asian or Muslim backgrounds at airports and government buildings. Why it matters for India's GS syllabus The piece is a useful lens for the "effect of policies and politics of developed and developing countries on India's interests" component of GS-II, and for comparative study of how counter-terrorism law-making (India's own UAPA amendments, NIA strengthening) parallels or diverges from the post-9/11 U.S. legal expansion. The critical view The argument is a first-person, opinion-based retrospective rather than a comparative policy study; it does not weigh counterfactual costs of inaction in Afghanistan, and its claim about the Iran conflict is presented without the same level of detail as its account of Iraq, so the comparison across the three interventions is not evenly evidenced. Institutions & terms to know Department of Homeland Security (DHS): U.S. federal department created after 9/11 to coordinate domestic security functions. Immigration and Customs Enforcement (ICE): U.S. federal agency created as part of the same post-9/11 reorganisation. ✎ Mains Practice Question "The policy response to a terrorist attack can cause more lasting damage than the attack itself." Examine this proposition with reference to the post-9/11 United States, and draw out lessons for the design of counter-terrorism law in democracies. 15 marks · 250 words

The memorandum followed a Parliamentary Committee on Public Undertakings report noting NHPC's concern that Gram Sabha consent requirements were delaying its projects. The Campaign for Survival and Dignity (CSD), a national platform of Adivasi and forest-dweller groups, has called the Ministry's position factually and legally untenable. The statutory position MoTA was assigned responsibility for "all matters including legislation relating to the rights of forest dwelling Scheduled Tribes on forest lands" through a March 2005 amendment to the Government of India (Allocation of Business) Rules, 1961. Section 11 of the FRA, 2006 designates MoTA as the nodal authority for implementing the Act, including rules and guidelines on Gram Sabha consent before forest clearance under the Forest (Conservation) Act, 1980. The Supreme Court's Niyamgiri judgment [(2013) 6 SCC 476] affirmed free, prior and informed consent of Gram Sabhas as a prerequisite for forest clearance. Figure 1 — Where Gram Sabha consent sits in the forest-clearance process FRA rightsrecognition(MoTA, nodal)Gram Sabhaconsent (FPIC)Niyamgiri, 2013Stage-II forestclearanceForest (Conservation)Act, 1980MoTA's 31 August OM disputes its own role at this consent step CSD argues the sequence — rights recognition, Gram Sabha consent, then clearance — is settled law that the August memorandum contradicts. The critical view CSD cites government data that roughly 3,05,945 hectares of forest land were approved for non-forest use between 2008-09 and 2022-23 without full FRA compliance, disputing the claim that consent requirements are the main cause of project delays. The Parliamentary Committee has also suggested lowering the consent threshold from 100% to 70–75%, a proposal CSD calls a misreading of Gram Sabhas' statutory powers. Institutions & terms to know Free, Prior and Informed Consent (FPIC): the Gram Sabha consent standard affirmed in the Niyamgiri case. Stage-I / Stage-II clearance: the two-stage approval process for forest diversion under the Forest (Conservation) Act, 1980. PESA, 1996: read alongside FRA as the constitutional basis for Gram Sabha authority over forest governance. ✎ Mains Practice Question Examine the statutory basis for Gram Sabha consent in forest diversion decisions under the Forest Rights Act, 2006. What risks does diluting this requirement pose for tribal rights and forest governance? 15 marks · 250 words 02 MHA Proposes New Chapter K Under Article 371 for Ladakh GS-II · Polity — Special Provisions, UT GovernancePrelims + MainsThe Hindu The Union Home Ministry has proposed a directly elected body for Ladakh through a new constitutional provision under Article 371, tentatively called Chapter K, though civil society representatives say no detailed draft has yet been shared. ◈ Background & Context Ladakh became a Union Territory without a legislature in 2019 after losing special status along with the erstwhile State of Jammu and Kashmir under the reorganisation following the reading down of Article 370. At a 9 September meeting, MHA officials told the Leh Apex Body (LAB) and Kargil Democratic Alliance (KDA) that the proposed body would be directly elected, with legislative powers over land, culture, language, forests, environment and natural resources. The ministry did not share a written draft on the body's wider legislative, executive or financial powers. Figure 2 — Jammu & Kashmir and Ladakh, post-2019 reorganisation Ladakh (Leh and Kargil districts) has been a separate Union Territory without a legislature since the 2019 reorganisation. Boundary depiction consistent with Government of India norms; reproduced for educational use. Where the demands stand The LAB and KDA have been separately demanding full statehood and inclusion of Ladakh under the Sixth Schedule, which grants autonomous district councils in tribal areas. Activist Sonam Wangchuk has warned of a fresh agitation from 19–24 September if the Centre does not give assurances within a week, linking the dates to the anniversary of the September 2025 violence in Leh. A planned Kargil–Leh padyatra, timed to the community's "Martyrs' Month" observance, was postponed after the Centre scheduled talks. Institutions & terms to know Article 371: enables special provisions for specific States/regions; a new Chapter K would extend this framework to Ladakh. Article 240: empowers the President to make regulations for certain Union Territories, referenced as the residual subject-matter basis for the proposed body. Sixth Schedule: provides autonomous district councils with legislative and judicial powers in specified tribal areas of the North-East — the alternative framework Ladakh groups are also seeking. The critical view Civil society representatives note that the September proposal largely repeats what was discussed at an earlier 22 May meeting, without a written draft defining the body's actual legislative, financial or executive powers — leaving the scope of the promised autonomy unclear more than a year after Ladakh's Sixth Schedule demand gained national attention. ✎ Mains Practice Question Discuss the constitutional options available to grant greater legislative autonomy to Union Territories without a legislature, with reference to the demands raised by Ladakh. 15 marks · 250 words Science & TechnologyGeneral Studies Paper III 03 CosmoCube: A Lunar Far-Side Satellite to Detect the Universe's First Radio Signal GS-III · S&T — Space Technology, AstronomyPrelims + MainsScience Desk report Researchers led by the Royal Astronomical Society have proposed CosmoCube, a suitcase-sized satellite that would use the Moon's far side as a shield from Earth's radio noise to detect the faint 21-centimetre signal from the universe's earliest, starless period. ▤ Mission at a Glance Target signal: the 21-cm radio line emitted by neutral hydrogen, dating to more than 13.5 billion years ago. Shielding mechanism: the Moon's far side blocks Earth-originated radio interference (FM radio, telecom, satellites) that swamps the signal on Earth. Orbit profile: around 40 minutes shielded per 2-hour lunar orbit; a proposed 2-year mission could gather roughly 1,000 hours of usable data. Timeline: the team states the mission could be ready for launch in about five years, subject to funding (researcher projection). Competing pressure: the U.S. and India are among countries planning missions to the lunar far side, which could add radio interference to the same region. Why the early universe is hard to observe After the Big Bang, the universe entered a roughly 150-million-year "cosmic dark age" before the first stars formed. Neutral hydrogen from this period produces the faint 21-cm signal, but Earth's ionosphere blocks the relevant low frequencies, and human radio transmissions overwhelm what does get through. Figure 3 — CosmoCube, artist's impression CosmoCube would use a lightweight radio antenna and repeatedly check its own position to separate genuine cosmic signal from spacecraft-generated interference. Image courtesy Surrey Space Technology Ltd; reproduced with credit for educational use. Figure 4 — Timeline of the cosmic dark age and reionization CosmoCube targets the period between roughly 380,000 years and 1 billion years after the Big Bang, when the universe transitioned from dark and neutral to reionized. Image courtesy NASA / WMAP Science Team; reproduced for educational use. Institutions & terms to know PRATUSH: India's own planned mission to study the cosmic dark age using a similar radio-astronomy approach, cited alongside CosmoCube. Epoch of Reionization: the period when the first stars and galaxies ionised the surrounding neutral hydrogen, ending the cosmic dark age. 21-cm hydrogen line: the specific radio wavelength emitted by neutral hydrogen, used to trace conditions before the first stars formed. The critical view The mission remains a proposal without confirmed funding or a launch contract, and its own five-year timeline is a project estimate rather than a commitment; the article itself flags that growing lunar far-side traffic from multiple countries' missions could erode the very radio-quiet environment the mission depends on. ✎ Mains Practice Question Discuss the scientific rationale for using the Moon's far side for radio astronomy, with reference to missions such as CosmoCube and India's PRATUSH. 10 marks · 150 words 04 Mercury May Be Shrinking 30% Faster Than Previously Estimated GS-III · S&T — Planetary SciencePrelims-orientedAP wire report A study by researchers at the German Aerospace Center's Institute of Space Research finds that Mercury's diameter may have shrunk by as much as 14 miles (23 km) — about 30% more than earlier estimates — as its iron core cools and contracts. ◈ Background & Context Mercury, the solar system's smallest and innermost planet at roughly 3,000 miles (4,900 km) across, has been contracting since its formation 4.5 billion years ago as its oversized iron core cools, tightening the crust like a girdle. Researchers compared maps of surface faults (signs of contraction) with newer maps of surface roughness, finding fewer shrinkage wrinkles in the roughest areas — suggesting some wrinkles are hidden under impact debris. The BepiColombo spacecraft (a joint European–Japanese mission) is expected to enter Mercury orbit in November 2026 and could confirm the revised shrinkage estimate with its laser altimeter. Only two prior missions have visited Mercury: NASA's Mariner 10 (1970s) and MESSENGER (2010s), whose data underpinned earlier shrinkage estimates. Institutions & terms to know BepiColombo: joint ESA–JAXA mission en route to Mercury, expected to enter orbit in November 2026. MESSENGER: NASA's 2010s Mercury orbiter mission whose data is being reassessed in this study. ✎ Mains Practice Question What does the ongoing contraction of Mercury reveal about planetary thermal evolution, and how do orbiter missions like BepiColombo help verify such findings? 10 marks · 150 words Environment & EcologyGeneral Studies Paper III 05 Rare East Asian Herb Recorded in India for the First Time, in Arunachal Pradesh GS-III · Environment — Biodiversity, New Species RecordsPrelims-orientedThe Times of India, Dehradun Researchers from the Wildlife Institute of India and the Uluberia Botanical Institute Herbarium have documented Ophiopogon japonicus, an East Asian medicinal herb, in Arunachal Pradesh's West Kameng district — the species' first confirmed record in India. ▤ The finding Species: Ophiopogon japonicus (Thunb) Ker Gawl, family Asparagaceae; common name dwarf lilyturf or mondo grass. Location: moist, shaded forest floor at 2,185 m, along the Shergaon–Gyuto monastery road, West Kameng district. Native range: China, Japan, Korea and Nepal, typically at 200–2,800 m elevation. Prior Indian records: seven other Ophiopogon species already recorded in India; an 1830s Kumaon specimen attributed to N. Wallich's catalogue was never taxonomically confirmed. Published in: a peer-reviewed Springer Nature journal, led by Dr. Ayan Kumar Naskar. Figure 5 — Ophiopogon japonicus habitat The species is identified by its grass-like leaves and blue, berry-like fruits. Representative field image; reproduced for educational use. Why it matters The find extends the species' known distribution into the Eastern Himalaya, a botanically under-surveyed region, and adds to India's recorded flora. The plant's tuberous roots (Ophiopogonis Radix, or Maidong) have long been used in traditional Chinese medicine, with reported anti-inflammatory, antioxidant, immunomodulatory and cardioprotective properties in rhizome extracts (researcher-reported, not independently verified here). Researchers flag threats to the population from its roadside habitat, including road construction and landslides, and have called for further surveys across the north-east. ✎ Mains Practice Question Discuss the significance of new species records from under-surveyed regions like the Eastern Himalaya for biodiversity conservation policy in India. 10 marks · 150 words Internal Security & SocietyGeneral Studies Paper I / II / III 06 Doctors' Body Flags Misplaced Protein Anxiety Fuelled by Social Media GS-I/II · Society — Health & NutritionMains-orientedThe Hindu A White Paper by the Physicians Association for Nutrition, India (PAN-India), released around National Nutrition Week, argues that India's protein discourse has become fixated on grams and product marketing rather than overall dietary adequacy. ▤ The numbers ICMR-NIN recommendation: about 0.83 g protein per kg body weight per day for a healthy adult — roughly 50 g for a 60-kg adult. Higher-need groups: children in growth phases, breastfeeding women, sportspersons and older adults may need up to 2 g/kg/day. National Nutrition Week: observed 1–7 September; the White Paper is titled "Rethinking Protein in Plant-Based Diets." The paper's key arguments It challenges the common claim that animal protein is "complete" and plant protein "incomplete" — plant foods contain all nine essential amino acids, only in different proportions. In a varied, adequate-calorie diet, specific proteins need not be combined at every single meal; traditional pairings like rice-dal or roti-chana remain useful but are not strictly necessary at each sitting. Protein supplements are not routinely necessary for healthy adults, though they may help athletes, older people with poor appetite, or those on GLP-1 weight-loss medications, which carry a muscle-loss side effect. Why it matters The paper's release coincides with new FSSAI food-labelling mandates and comes as social media increasingly substitutes for professional dietary advice — clinicians cited cases of self-directed high-protein diets causing dangerous potassium and phosphorus levels in patients with kidney disease. ✎ Mains Practice Question "Nutrition advice on social media often substitutes for, rather than supplements, professional guidance." Discuss this concern with reference to India's current protein discourse. 10 marks · 150 words 07 When an AI Chatbot Becomes the First Confidant in a Mental Health Crisis GS-I/II · Society — Mental Health, Technology & GovernanceMains-orientedThe Hindu Psychiatrists report that a growing share of patients, particularly younger ones, turn to AI chatbots before consulting a professional when in emotional distress, raising concerns about delayed care and reinforced hopelessness in suicide-risk situations. ▤ The numbers A U.S. survey of 1,009 people aged 12–21 (JAMA Pediatrics) found 19.2% had used AI chatbots for mental health advice in 2025; nearly 43% of these used them at least monthly, and 5.8% daily or almost daily. Nearly two-thirds of these users had not told anyone about the practice. Among over 620,000 analysed ChatGPT conversations, 4.9% broadly touched on mental health, though only 0.21% met a strict definition of an identifiable person seeking mental health help. In one clinical setting, psychiatrists estimated 60–70% of patients discuss personal problems with AI before speaking to a professional. Where the risk lies Chatbots are reported to be better at recognising very low- and very high-risk situations, but weaker at distinguishing intermediate suicide-risk levels — a concern since distress is often expressed indirectly.
