rchives (PRELIMS  Focus) Greenfield Airports Context: The Andhra Pradesh government has drawn up plans to develop greenfield airports at Srikakulam, Bhogapuram, Tuni–Annavaram, Tadepalligudem, Ongole, Dagadarthi, Kuppam and Nagarjuna Sagar. About Greenfield Projects: A greenfield airport is a new aviation facility built from scratch on previously undeveloped land. India’s first Greenfield airport built in the northeastern region is Pakyong Airport, located in Sikkim. The development of Greenfield airports is regulated by the Greenfield Airports (GFA) Policy, 2008. As per the Policy, a State Government or an Airport Developer, willing to establish an airport is required to send a proposal to the Ministry of Civil Aviation (MoCA) for 2-stage approval i.e. ‘Site-Clearance’ followed by ‘In-Principle’ approval. Advantages of Greenfield Projects: Engineers do not have to spend time tearing down old buildings, making the construction process faster and more efficient. Enhances regional and international air travel. Helps decongest existing airports in urban areas. Encourages investment and trade in surrounding regions. Can be planned with eco-friendly measures like green energy and sustainable construction. Source: THE HINDU Collegium System Context: The Supreme Court Collegium headed by Chief Justice of India B.R. Gavai on Monday recommended the elevation of the Chief Justices of the Bombay and Patna High Courts, Justices Alok Aradhe and Vipul Manubhai Pancholi, respectively, as top court judges. Appointment of judges in HCs and SC: The Judges of the Supreme Court are appointed by the President under clause (2) of Article 124 of the Constitution. Judges of the higher judiciary are appointed through the collegium system. The term “collegium” is not mentioned in the Indian Constitution but has been established through judicial pronouncements. Salaries, allowances, privileges, leave, and pension of Supreme Court judges are determined by Parliament. The Salaries, Pension, and Allowances of the Supreme Court Judges are charged upon the Consolidated Fund of India. After retirement, a judge of the Supreme Court is prohibited from practicing law in any court in India or pleading before any government authority. Evolution of Collegium System: First Judges Case (1981): It declared that the “primacy” of the CJI’s (Chief Justice of India) recommendation on judicial appointments and transfers can be refused for “cogent reasons.” Second Judges Case (1993): It introduced the Collegium system, holding that “consultation” really meant “concurrence”. It added that it was not the CJI’s individual opinion, but an institutional opinion formed in consultation with the two senior-most judges in the Supreme Court. Third Judges Case (1998): SC on the President’s reference (Article 143) expanded the Collegium to a five-member body, comprising the CJI and four of his senior-most colleagues. Source: THE HINDU Salwa Judum Context: A group of 18 retired judges of the Supreme Court and High Courts have penned a joint statement against Home Minister Amit Shah’s remarks on the Supreme Court’s Salwa Judum judgment, saying that such “prejudicial misinterpretation” will have a “chilling effect on the judges of the Supreme Court, shaking the independence of the judiciary”. About Salwa Judum: Meaning “Peace March” or “Purification Hunt” in the language of the Gonds, the Salwa Judum was a militia specifically mobilised with the intention of countering the Left-Wing Extremism (LWE) or naxalism in the Chhattisgarh region. It consisted of local tribal youth mobilized for resistance against outlawed armed naxalites. The group was reportedly backed by government machinery in Chhattisgarh. There were reports that Salwa Judum forcibly recruited minor boys for its armed forces. According to a survey by the Forum for Fact-finding Documentation and Advocacy (FFDA), over 12,000 minors were being used by the Salwa Judum in the southern district of Dantewada. The Salwa Judum displaced large numbers of villagers. They even killed those that refused to leave, accusing them of being naxalite collaborators. Following a number of petitions, the Supreme Court ordered the state government in 2008 to refrain from allegedly supporting and encouraging the Salwa Judum. In 2011, the Supreme Court of India in a case filed by Nandini Sundar and others declared the militia to be illegal and unconstitutional, and ordered its disbanding. However, despite the order, the Salwa Judum remains a part of the auxiliary force of the state police. Other government initiatives to control Left-Wing Extremism (LWE): SAMADHAN doctrine is the one-stop solution for the LWE problem. It encompasses the entire strategy of government from short-term policy to long-term policy formulated at different levels. SAMADHAN stands for- S- Smart Leadership A- Aggressive Strategy M- Motivation and Training A- Actionable Intelligence D- Dashboard Based KPIs (Key Performance Indicators) and KRAs (Key Result Areas) H- Harnessing Technology A- Action plan for each Theatre N- No access to Financing The national strategy to counter LWE was formed in 2015 as a multipronged approach to combat LWE. Its main aim was to ensure participatory governance and protection of the rights of local tribals, inter alia. Operation Green Hunt was started in 2009-10 and massive deployment of security forces was done in the naxal-affected areas.

Source: THE HINDU Invasive plants Category: ENVIRONMENT Context : A new international study shows that invasive plants and animals have caused over $2.6 trillion in global damage since 1960, with costs in India severely underreported. Key Points Global Impact: Plants, arthropods, and mammals are the most damaging groups, affecting agriculture, forestry, fisheries, and infrastructure. India’s Blind Spot: Management costs are underreported by over 1,100%, reflecting weak documentation and funding. Drivers of Costs: Losses stem from both economic damage and expenses for detection, control, and eradication. Gaps: India lacks robust data, funding, and coordinated strategies, worsening ecological and financial risks. Way Forward: Experts urge stronger policies, better data systems, and global cooperation for prevention and management. Learning Corner: Invasive Species of India Invasive Alien Species (IAS) are non-native plants, animals, or microbes introduced—intentionally or accidentally—that spread rapidly, harm native biodiversity, disrupt ecosystems, and cause economic loss. India, with its rich biodiversity, is especially vulnerable. Examples of Major Invasive Species in India Plants Lantana camara – A hardy shrub from Central/South America; invades forests, suppresses native plants. Parthenium hysterophorus (Congress Grass) – From tropical America; affects agriculture, causes skin allergies and respiratory issues. Eichhornia crassipes (Water Hyacinth) – Aquatic weed from the Amazon; clogs water bodies, reduces oxygen, harms fisheries. Prosopis juliflora (Vilayati Babool) – From South America; dominates drylands, displaces native grasses. Animals Common Carp & Tilapia – Non-native fishes that outcompete local species, affecting inland fisheries. African Catfish (Clarias gariepinus) – Aggressive predator, threatens native fish diversity. Apple Snail (Pomacea canaliculata) – Damages paddy fields and aquatic vegetation. Insects / Others Papaya Mealybug (Paracoccus marginatus) – Destroys papaya and other crops. Fall Armyworm (Spodoptera frugiperda) – Major pest in maize, spreading rapidly in India.

The Piprahwa gems, sacred relics linked to Lord Buddha and discovered in 1898 at the Piprahwa stupa in Uttar Pradesh, were repatriated from Hong Kong to India in July 2025. These treasures include bone fragments, gem-inlaid reliquaries, gold ornaments, and ritual offerings enshrined by the Buddha’s Sakya clan. Once held by the Peppé family after colonial excavations, around 300 gem-encrusted artefacts resurfaced for auction in Hong Kong with an estimated value of $13 million before the Government of India intervened to secure their permanent return. The relics were ceremonially welcomed back, with plans to place them on public display at Piprahwa, Siddharthnagar. This repatriation is seen as a landmark in heritage diplomacy, marking the restitution of one of India’s most precious Buddhist treasures once thought lost to private collections. Learning Corner: Piprahwa Gems are sacred Buddhist relics discovered in 1898 at the Piprahwa stupa in Siddharthnagar, Uttar Pradesh. They include bone fragments, gem-studded reliquaries, gold ornaments, and ritual offerings, believed to have been enshrined by the Sakya clan of Lord Buddha. Discovery: Unearthed by British civil officer W.C. Peppé during colonial-era excavations. Significance: Considered among the earliest archaeological evidence directly linked to Lord Buddha and his relics. Heritage Journey: While most relics were deposited in the Indian Museum, Kolkata in 1899, some gems remained with the Peppé family and later surfaced in international auctions.

Source: THE INDIAN EXPRESS Direct Action Day Category: HISTORY Context: Static question. Can be directly asked in prelims The Great Calcutta Killing (August 16–19, 1946), triggered by the Muslim League’s call for Direct Action Day, witnessed one of the deadliest communal riots in India’s history, with 5,000–10,000 people killed. The violence between Hindus and Muslims engulfed Calcutta, marked by rioting, arson, and brutal reprisals. The violence exposed the deepening divide between communities, worsened by political tensions between the Muslim League and the Congress over Partition. Chief Minister H.S. Suhrawardy was widely blamed for failing to control the situation, as Calcutta effectively split along religious lines—a grim preview of the Partition bloodshed in 1947.  Learning Corner: Direct Action Day (16 August 1946) Background: Post–World War II, Britain prepared to leave India but Hindu–Muslim tensions escalated. The Cabinet Mission Plan (1946) had failed, particularly due to disagreement over grouping of provinces. The Muslim League, led by Muhammad Ali Jinnah, demanded a separate Pakistan. The Call: Jinnah announced 16 August 1946 as “Direct Action Day” to press for Pakistan. The League urged Muslims to demonstrate peacefully, but communal propaganda sharpened divides. Events: The day sparked the Great Calcutta Killings (16–19 August 1946). Riots left around 4,000 dead and thousands injured/displaced. Violence spread to Noakhali (Bengal), Bihar,

This move narrows statutory protection, making approvals for mining, infrastructure, and other development projects in tiger habitats easier. Earlier, NTCA had assured that all scientific data—such as telemetry studies, tiger conservation plans, and wildlife movement models—would be considered, but the new stance reduces scope. Conservationists warn this undermines landscape connectivity vital for tiger movement, gene flow, and survival. NTCA’s own earlier reports had stressed that least-cost routes were only the bare minimum, while broader corridors also required attention. The change benefits several pending projects but raises concerns about long-term tiger conservation and habitat security.

rchives (PRELIMS  Focus) SN 2023zkd Category: SCIENCE AND TECHNOLOGY Context:  Astronomers have observed a new type of supernova triggered by the violent interaction between a massive star and a black hole in a binary system, named SN 2023zkd. A massive star, at least 10 times the Sun’s mass, was locked in a tight orbit with a stellar-mass black hole. Over years, the black hole’s gravity stripped away the star’s outer hydrogen layer, exposing helium and causing abnormal brightening. As the orbit decayed, the gravitational stress reached a tipping point, leading to a supernova explosion that released more energy in a second than the Sun will emit in its lifetime. The black hole then consumed much of the stellar debris, becoming more massive. This is the first strong evidence that black holes can directly trigger supernovae in massive stars, not just influence them through accretion or mergers. It reshapes our understanding of how massive stars die and how black holes grow. The event was detected thanks to an AI-based system, which flagged unusual activity and prompted rapid follow-up observations. Archival data showed years of brightening prior to the explosion, confirming the gradual mass transfer process. The discovery highlights the role of black holes in catalyzing stellar deaths, the power of AI in astronomy, and provides new insights into the complex evolution of binary star systems. Learning Corner: Supernova A supernova is the catastrophic explosion of a star, resulting in a sudden, extremely bright outburst that may briefly outshine an entire galaxy. It represents the final evolutionary stage of certain stars and plays a critical role in enriching the interstellar medium with heavy elements (like iron, gold, uranium). Supernovae are key to the cosmic cycle of matter and are important markers for measuring cosmic distances (Type Ia). Types of Supernovae Type I Supernova Occurs in binary star systems, where a white dwarf accretes matter from its companion until it reaches the Chandrasekhar limit (~1.4 solar masses). Results in a thermonuclear explosion with no hydrogen lines in spectrum. Subtypes: Type Ia – Used as “standard candles” in cosmology for distance measurement. Type Ib and Ic – Collapse of massive stars stripped of hydrogen (Ib) and both hydrogen + helium (Ic). Type II Supernova Results from the core-collapse of a massive star (> 8 solar masses) after nuclear fuel exhaustion. Spectrum shows strong hydrogen lines. Produces either a neutron star or a black hole. Significance Enriches galaxies with heavier elements (stellar nucleosynthesis). Creates neutron stars, pulsars, or black holes. Provides tools to study dark energy and cosmic expansion (Type Ia).  SN 2023zkd: A New Class of Supernova Discovery & Uniqueness: Detected in July 2023 by the Zwicky Transient Facility, SN 2023zkd was not a typical stellar explosion. It is believed to be the strongest evidence of a black hole–triggered supernova, caused by the gravitational interaction between a massive star and its black hole companion. AI-based Early Detection: An AI system (Lightcurve Anomaly Identification and Similarity Search – LAISS) flagged its unusual light pattern months in advance, enabling astronomers to track the event in detail. Strange Pre-Explosion Behavior: The star displayed four years of continuous brightening before its final detonation, a highly unusual precursor not seen in ordinary supernovae. Double-Peaked Light Curve: Instead of one brightness peak, SN 2023zkd showed two separate re-brightening events after explosion—likely from the blast colliding with earlier ejected gas and then with more distant material. Cause of Explosion: Scientists suggest that as the star orbited closer to the black hole, intense gravitational stress stripped its mass and eventually triggered the explosion. Another theory is that the black hole shredded the star, and the debris collisions mimicked a supernova. In both cases, the black hole grew more massive. Scientific Significance: SN 2023zkd provides a new model of stellar death, showing how compact objects like black holes can induce supernova-like events. It also highlights the growing role of AI in astronomy for early detection and classification of rare cosmic phenomena. Source: REUTERS GST reforms Category: ECONOMICS Context : S&P Global Ratings has noted that India’s planned GST reforms, despite lowering tax rates and causing an initial revenue loss, are expected to boost long-term revenues by driving higher consumption. Estimates suggest a shortfall of about ₹85,000 crore initially, but rising demand could eventually add nearly ₹2 lakh crore in revenue. The reforms—moving towards a simpler two-slab structure of 9% and 18%—are expected to improve compliance, make accounting fairer, and support economic growth. HSBC adds that the GST revamp, along with a possible S&P credit upgrade and changes in global trade tariffs, could strengthen India’s fiscal discipline and investment climate. The success of these reforms, however, will depend on effective execution, coordination with the GST Council, and adjustments in revenue-sharing arrangements. Learning Corner: GST Council Constitutional Body: Established under Article 279A of the Constitution (via the 101st Constitutional Amendment Act, 2016). Composition: Chairperson: Union Finance Minister Members: Union Minister of State (Finance/Revenue) + Finance Ministers of all States & UTs with legislatures. Decision-Making: Decisions taken by 75% majority of weighted votes: Centre: 1/3rd weightage States: 2/3rd weightage Functions: Recommend GST rates, exemptions, thresholds, model laws, and special provisions for states. Decide on revenue sharing, dispute resolution, and simplification of compliance.

Data: U.S. labour market weakness, sharp rise in core inflation, and surge in producer prices. Global Impact Bonds Persistent inflation erodes value of long-dated bonds. If U.S. stagflation persists, G7 bond markets will be correlated → global sell-off in bonds. Pension funds and insurers especially vulnerable to inflation. Wall Street Investors expect U.S. growth to slow. Stagflation is now one of the two main concerns for global asset managers. Tech stocks remain strong, but small-cap indices are vulnerable. Currencies Stagflation → weaker U.S. dollar due to slower growth + higher inflation. Could benefit euro in relative terms. Global Spillover Since 1990, world stocks fell by ~15% whenever U.S. manufacturing data showed contraction + high prices. Even if stagflation is U.S.-centric, ripple effects will hit global portfolios. Learning Corner: Concepts of Inflation  Concept Key Feature Example Demand-Pull Inflation Excess demand pushes prices up (“too much money chasing too few goods”) Festive season demand in India Cost-Push Inflation Higher production costs passed to consumers Oil price hike → transport cost rise Stagflation Stagnant growth + high unemployment + high inflation U.S. in 1970s oil crisis Core Inflation Excludes food & fuel (volatile items) RBI tracks for monetary policy Headline Inflation Overall CPI including all items Retail inflation data released monthly Creeping Inflation Slow rise (1–3% annually) Normal inflation in stable economies Walking/Mild Inflation Moderate rise (3–10% annually) Growing economy with healthy demand Galloping/Hyperinflation Very high inflation (triple digits) Zimbabwe in 2000s, Germany in 1920s Disinflation Decline in rate of inflation (prices still rise but slower) CPI falling from 6% → 4% Deflation Fall in general price levels (negative inflation) Great Depression (1930s) Reflation Policy-driven inflation to boost demand Fiscal stimulus packages Imported Inflation Inflation caused by global price rise in imports India’s fuel-driven inflation Source:  THE HINDU S&P Rating Category: ECONOMICS Context: S&P Global Ratings raised India’s sovereign rating from BBB- to BBB after ~20 years.

rchives (PRELIMS  Focus) Coral reefs Category: ENVIRONMENT Context:  In Tamil Nadu’s Gulf of Mannar, a large-scale coral restoration programme has been carried out by the Suganthi Devadason Marine Research Institute (SDMRI) Process: Scientists identify degraded reefs for transplantation. Concrete frames and other substrates are deployed. Coral fragments from healthy reefs are transplanted onto these structures. Over time, the corals grow, forming new reefs. Scale of restoration: 5,550 artificial substrates deployed. 51,183 coral fragments transplanted. Around 40,000 sq. m. of degraded reefs restored. Cost: $111.7 per sq. m. of reef restored. Survival rates: Coral survival improved significantly — from 56.6% (2002–2004) to 71.6% (2015–2019). In Vaan Island alone, live coral cover rose from 31.6% to 42.1%. Impact: Coral species diversity restored (20 genera transplanted). Increased fish biomass and marine biodiversity. Local communities benefit via improved fisheries. Challenges: Climate change (warming seas, acidification). Natural disasters (2004 tsunami, 2016 coral bleaching). Anthropogenic pressures (fishing, pollution). Way forward: Scaling up restoration, continuous monitoring, community participation, and stricter protection measures. Learning Corner: Methods of Coral Restoration Coral Gardening (Nursery Method) Involves growing coral fragments in underwater or land-based nurseries. Once they mature, corals are transplanted back to degraded reefs. Suitable for branching and fast-growing species like Acropora. Larval Propagation (Sexual Reproduction Method) Collects coral gametes (eggs and sperm) during spawning events. Fertilized larvae are cultured in controlled environments, then settled on artificial substrates. Ensures genetic diversity and resilience against climate change. Coral Transplantation Direct transfer of corals from healthy sites to degraded reefs. Works as an emergency intervention, but may damage donor sites. Artificial Reefs (Substrate-based Restoration) Use of concrete blocks, metal frames, ceramic tiles, or eco-engineered substrates to provide stable attachment surfaces for coral growth. Enhances fish aggregation and reef resilience. Cryopreservation & Assisted Breeding (Emerging Techniques) Cryopreservation of coral sperm/larvae for future restoration. Selective breeding and assisted evolution to enhance stress tolerance (e.g., heat or disease resistance). Source: THE HINDU Connexin proteins Category: SCIENCE AND TECHNOLOGY Context : The term can directly asked in Prelims Summary Discovery: Researchers identified Connexin proteins (Cx37 and Cx40) as key to rapid blood flow coordination. These proteins form gap junctions that link artery walls, allowing electrical-like signals to travel faster than chemical messengers. In mice, these signals moved fuel-delivery instructions across vessels at nearly the speed of neurons firing. Findings: Gap junction signalling enables arteries to widen quickly and in sync, ensuring timely delivery of blood to active brain regions. Blocking connexins slowed the signal, proving their role in high-speed vascular coordination. Significance: Helps explain how the brain prevents lapses in attention or function. Offers insights for disease research—loss of gap junction function in aging or small vessel disease may impair brain blood flow. Valuable for AI-guided brain models, stroke research, and drug delivery strategies. Learning Corner: Connexin Proteins Connexins are a family of membrane proteins that form gap junction channels between adjacent cells. Each gap junction is made of two hemichannels (connexons), and each connexon consists of six connexin subunits. These channels allow direct intercellular communication by permitting the passage of ions, metabolites, and signaling molecules. More than 20 types of connexins are identified in humans (e.g., Connexin43, Connexin26). Functions Cell–cell communication: Essential for coordination of cellular activities. Electrical coupling: Maintains synchronized contraction in cardiac and smooth muscle. Developmental regulation: Plays roles in embryonic growth, tissue differentiation. Metabolic cooperation: Enables nutrient and signal sharing between cells. Source:  THE HINDU E20 petrol Category: POLITY Context: India launched E20 petrol (20% ethanol-blended fuel) in 2023, with a target of E20 nationwide by 2025 (advanced from 2030). Summary Vehicle Owners’ Reaction: New vehicles from 2023 carry E20-compatible stickers. Older vehicles may face mileage drops and higher maintenance costs. Surveys show ~77% of vehicle owners in some districts opposed the shift due to cost concerns. Economic & Environmental Impact: Reduced carbon dioxide emissions by 700 lakh tonnes (Ministry of Petroleum and Natural Gas). Boosts India’s rural economy by supporting sugarcane farmers. However, heavy reliance on sugarcane raises concerns over water use, food security, and ecological stress. Global Dimension: The U.S. has pushed India to relax ethanol import restrictions; trade issues remain contentious. Ethanol production in India is largely domestic, supported by government policies and financial incentives. EV Transition vs Ethanol: Ethanol blending seen as a bridge fuel toward cleaner energy. EV adoption in India is slower due to high costs, inadequate charging infrastructure, and global supply chain issues (e.g., rare earth imports from China). Ethanol helps reduce emissions in the short run while EV ecosystem matures. Challenges: Dependence on water-intensive sugarcane. Limited diversification into maize and other biofuel crops. Vulnerability to trade policies and international market fluctuations. Balancing ethanol promotion with the long-term EV transition. Learning Corner: Ethanol Blending in India  Ethanol Blended Petrol (EBP) Programme launched in 2003, scaled up in 2013. Aim: Reduce dependence on crude oil imports, cut carbon emissions, support farmers, and promote cleaner fuel. Target: 20% blending (E20) by 2025-26 (advanced from 2030). Current Status (as of 2025) 12% national blending average achieved in 2023-24. Some states (like Maharashtra, Uttar Pradesh, Karnataka) have achieved >12% blending. India has become the 3rd largest producer of ethanol after USA and Brazil. Feedstocks for Ethanol Sugar-based: Sugarcane juice, B-heavy molasses, C-molasses. Starch-based: Maize, broken rice. Other sources: Damaged food grains, surplus rice from FCI. Second-generation (2G) ethanol: Agricultural residues like rice straw, wheat straw, bagasse. Government Initiatives National Policy on Biofuels (2018): Promotes 1G & 2G ethanol, biodiesel, advanced biofuels. Ethanol Interest Subvention Scheme: Soft loans for distillery capacity expansion. SATAT Scheme: For compressed biogas, complementing ethanol. GOBARdhan Scheme: Linking waste to wealth for rural bioenergy. PM-PRANAM Scheme (2023): Encourages alternative fertilizers & biofuels.

rchives (PRELIMS  Focus) Alaska Summit 2025 Category: INTERNATIONAL Context:  U.S. President Donald Trump is set to meet Russian President Vladimir Putin in Anchorage, Alaska, in a high-stakes attempt to negotiate an end to the Ukraine war. This is the first U.S.-Russia leaders’ meeting since June 2021. Europe sees the summit as crucial with Ukraine’s fate and continental security at stake. What Trump Wants: A ceasefire and a “win” that boosts his global image. To showcase himself as a deal-maker capable of ending conflicts. Recognition through a peace achievement, possibly even linked to a Nobel Peace Prize narrative. What Putin Wants: Recognition of Russia’s annexations and security buffer in Ukraine. A halt to NATO’s eastward expansion and security guarantees. Western sanctions relief, while keeping occupied territories under Russian control. What Zelenskyy Wants: No compromise on Ukraine’s sovereignty or territorial integrity. Continued Western military and financial support. A durable peace deal that does not force Ukraine to give up territory. European Stake: EU leaders (France, Germany, UK) emphasize unity against Russia. Europe fears that U.S.-Russia talks may sideline European interests, just like in 1945 when post-war Europe was decided without French input. India’s Concerns: India is indirectly impacted by U.S. sanctions on Russia, particularly affecting energy imports and fertilizer supplies. U.S. has imposed a 25% tariff penalty on India for Russian oil purchases and a 25% tariff on Indian exports to the U.S. New Delhi hopes Trump emerges with a “win” that stabilizes the situation, as prolonged instability hurts its economy and geopolitical balancing.

rchives (PRELIMS  Focus) Dhirio Category: CULTURE Context:  Goa’s traditional bullfighting, and recent demands by MLAs across party lines to legalise it. Key Points: Historical & Cultural Significance: Traced back to the Harappan civilisation and Portuguese era. Traditionally held after harvest season as community entertainment. Bulls fight until one falls or flees, sometimes causing serious injuries. Events attract large crowds, including politicians and dignitaries. Current Ban: Prohibited under the Prevention of Cruelty to Animals Act, 1960 after a fatal 1996 incident. High Court banned all animal fights, but events still occur clandestinely, often publicised through private channels. Popular for betting, including among the Goan diaspora. Legalisation Debate: Proponents: Claim no cruelty, compare it to regulated sports like boxing, argue it boosts tourism and rural economy. Opponents (animal rights activists): Call it violent, cruel, and primarily for gambling; oppose exceptions for dhirio. Government Response: Goa CM Pramod Sawant has promised to examine the issue. Previous attempts to legalise under regulated frameworks have been discussed but not implemented. Learning Corner: Traditional Bullfighting in India: Jallikattu (Tamil Nadu): Bull-taming sport held during Pongal festival; participants attempt to grab a bull’s hump and hold on. Dhirio (Goa): Bull-versus-bull fights, banned under the Prevention of Cruelty to Animals Act, 1960; proponents seek regulated revival. Kambala (Karnataka): Though not bullfighting, involves buffalo races in waterlogged fields during the harvest season. Traditional Sports in India: Mallakhamba (Maharashtra & MP): Gymnastics and wrestling techniques performed on a wooden pole or rope. Thang-ta (Manipur): Martial art combining armed combat with sword and spear. Vallam Kali (Kerala): Snake boat races during Onam. Silambam (Tamil Nadu): Weapon-based martial art using bamboo staffs.

Source: THE INDIAN EXPRESS Plate tectonics Category: GEOGRAPHY Context : This can directly be asked in prelims Scientific Significance: Originated along the boundary between the Indian and Eurasian Plates. This region, especially the Eastern Himalayas, is highly seismically active, with plate convergence rates varying from 10 to 38 mm/year. The earthquake’s mixed thrust and strike-slip motion made it unique compared to typical Himalayan quakes. Caused major surface ruptures, mountain collapses, and altered landscapes permanently. Geological Context: The Great Assam Earthquake was caused by collision of continental plates, creating a complex tectonic zone. The Eastern Himalayas differ from the central arc, as structures here involve multiple faults linked to the Assam syntaxis. Past data shows large quakes in the area in 1548, 1596, 1697, and medieval events between 1262–1635. Implications for the Future: The region remains the most seismically active in the Himalayas and could generate another 1950-scale quake. Predicting timing, location, and magnitude remains impossible with current knowledge. Urban expansion, infrastructure, and population density make a future quake potentially more devastating. Learning Corner: Plate Tectonics  Plate tectonics is the scientific theory that the Earth’s outer shell (lithosphere) is divided into large, rigid plates that float on the semi-molten asthenosphere beneath. These plates move slowly due to convection currents in the mantle caused by heat from Earth’s interior. Key Points: Major Plates: Pacific, Eurasian, African, Indo-Australian, North American, South American, and Antarctic, along with smaller plates. Plate Boundaries: Convergent: Plates move towards each other → mountain building, subduction zones, volcanoes. Divergent: Plates move apart → mid-ocean ridges, seafloor spreading. Transform: Plates slide past each other → earthquakes. Geological Impact: Explains distribution of earthquakes, volcanoes, mountain ranges, ocean trenches, and continental drift. Driving Forces: Mantle convection, slab pull, and ridge push.
