UPSC CSE Why

4) Semeru Volcano – Why Eruptions Differ What happened • Mount Semeru in Indonesia erupted, spewing large ash clouds and debris. Issue raised • Why some eruptions are gentle (Hawaiian type) while others are explosive (Semeru type). Current context • Magma composition determines explosivity: – Runny magma lets gases escape → mild eruptions – Thick magma traps gases → violent explosions and tephra blasts Why it matters • Helps understand volcanic hazards in the Ring of Fire region. • Supports disaster preparedness in vulnerable Asian populations. 5) Expansion of Stone Quarries in Kerala What happened • After Kerala banned river-sand mining in 2016, stone quarrying increased sharply. • New research shows quarry areas expanded by over 170 percent in one year. Issue raised • Quarrying now happens near ecological hotspots and protected areas. • Concerns about biodiversity loss and river-basin instability. Current context • M-sand made from crushed rock became the dominant construction material after river sand ban. • Demand for sand keeps rising with urbanisation. Why it matters • Quarry expansions threaten sensitive Western Ghats ecology. • Highlights trade-off between development and environmental protection. 6) Pharmacogenomics – Tailored Prescriptions What happened • Article explains how genetic testing allows doctors to personalise medication based on individual metabolic differences. Issue raised • Standardised “one-dose-fits-all” prescribing causes adverse reactions, ineffective dosing and avoidable hospitalisations. Current context • Genetic variations affect how patients metabolise drugs like antidepressants, anti-clotting agents, and pain medicines. • Some countries already integrate pharmacogenomics into routine care. • India is beginning to explore adoption. Why it matters • Can reduce adverse drug reactions and improve treatment success. • Represents the shift from population-based to precision-based medicine.

More in the next message 1) Colombo Security Conclave – Maritime Safety & Counter-Terrorism What happened • India hosted the 7th NSA-level Colombo Security Conclave (CSC) meeting in New Delhi with Maldives, Mauritius, Sri Lanka, Bangladesh, Seychelles and Malaysia. • Discussions focused on regional security cooperation. Issue raised • Growing challenges in the Indian Ocean: terrorism, radicalisation, trafficking, cyber threats, and maritime crimes. • Need for coordinated action among member states. Current context • Recent attacks, including attempted terror activity in Delhi and cybercrimes, pushed the need for stronger coordination. • Mauritius was accepted as a full CSC member. • Maldives attended at a high level despite strained ties. Why it matters • CSC has become a key Indian Ocean security grouping. • India uses CSC to strengthen its maritime influence and push cooperative security architecture in the region. 2) India’s Indigenous Gene-Editing Tool (CRISPR Cas9) What happened • CSIR-IGIB transferred India’s indigenous CRISPR gene-editing tool to the Serum Institute of India for clinical trials. • The first trial will target sickle cell disease. Issue raised • Imported CRISPR therapies cost over ₹18 crore, making them inaccessible. • India needs low-cost genetic treatments for tribal populations where sickle cell disease is common. Current context • The tool, named “Bira-101,” is ready for Phase I trials. • It uses a locally developed CRISPR system with Indian patents. • Works differently from the global therapy “Casgevy,” which is extremely expensive. Why it matters • Can reduce cost of genetic treatment by 10–20 times. • Strengthens India’s biotech self-reliance and aligns with affordable healthcare goals. 3) Small vs Big Car Debate – New Emission Norms What happened • India proposed Phase-III Corporate Average Fuel Efficiency (CAFE) norms from FY28. • Carmakers are split on whether the standards unfairly burden small-car manufacturers. Issue raised • Weight-based formula means small cars must improve efficiency more than heavier SUVs. • Small-car makers argue this raises costs and could hurt affordability. Current context • Maruti fears small cars like Alto or Wagon R may become unviable. • Tata argues the norms are achievable but costly. • Manufacturers want adjustments to prevent price hikes. Why it matters • India’s budget-car market is crucial for low-income buyers. • Stricter rules push the industry toward cleaner but more expensive vehicles.

1. Gustav Klimt portrait sold for $236 million What happened? * A Gustav Klimt portrait (“Portrait of Elisabeth Lederer”) sold at Sotheby’s, New York for $236.4 million, a record for a modern artwork. Issue raised * The painting helped its Jewish subject survive the Nazis by convincing them she “descended from Klimt.” * Raises questions on provenance, Nazi-era art transfers, and restitution. Current context * Only two full-length portraits by Klimt remain privately owned. * This piece came from the Lauder family collection; multiple Klimt works from the same collection were also auctioned. * High global interest in artworks rescued from wartime histories. Why it matters * Highlights the ongoing value and historical baggage of Nazi-era artworks. * Shows how art markets are strongly driven by rarity + wartime narratives. * Adds to discussions around restitution, ownership, and stolen cultural property. 2. Attribution science & linking disasters to emitters What happened? * Article explains attribution science, which studies how climate change influences extreme weather events. * Delhi’s severe air pollution and Cyclone Remal aftermath used as examples. Issue raised * It is difficult to assign exact responsibility (emitters → disasters). * Limitations in modelling, sparse local data, and overlapping pollution sources create uncertainty. Current context * India plans to expand capacity in extreme-event attribution. * Global warming is projected to exceed 2°C; more extreme events expected. * Governments, insurers, and courts increasingly rely on attribution science for accountability and compensation. Why it matters * Attribution will shape future climate litigation, liability for emissions, and compensation for victims. * Helps governments justify climate adaptation budgets. * Important for India, which faces rising climate-related losses.

1. ‘Parasocial’: Cambridge Word of the Year The story so far: * Cambridge Dictionary selected “parasocial” as the 2025 Word of the Year due to rising AI companionship trends. * Definition updated to include “possibility of a relationship with AI.” Key points: 1. Term coined in 1956 by sociologists Horton & Wohl for one-sided spectator–performer relationships. 2. Now includes relationships with celebrities, influencers, AI bots, and digital characters. 3. Social media deepens illusion that fans “know” the celebrity closely. 4. Parasocial ties aren’t harmful by default; issues arise when they replace real interactions. 5. AI companions and chatbots turning from novelty to social necessity is the new concern. 6. Reflects a global shift towards loneliness + digital substitutes for connection. 2. Ginkgo-toothed Beaked Whale Spotted The story so far: * Scientists recorded the rare ginkgo-toothed beaked whale (Mesoplodon ginkgodens) in the wild near Baja California, Mexico. Key points: 1. Part of 24 species of beaked whales—2nd most diverse cetacean group after dolphins. 2. Known from very limited stranding records; rarely observed alive. 3. Grows up to 17.3 ft; both sexes look similar. 4. Has a robust, heavily scarred body**—indicating low aggression among males. 5. Beaked whales are the **deepest-diving mammals, surfacing only briefly. 6. Extremely shy & easily frightened, especially when approached by boats. 3. ‘Agentic AI’: Tech’s New Buzzword The story so far: * “Agentic AI” is the industry’s newest pitch, claiming systems that can plan, act, and learn autonomously. Key points: 1. Goes beyond chatbots—meant to behave like autonomous teammates performing multi-step tasks. 2. MIT & Boston Consulting Group report defines it as a new class of systems. 3. Tech giants (Amazon, Google, IBM) expect agents to manage tasks like shopping, bookings, scheduling. 4. Promise: break down high-level goals into steps and act on them. 5. Concern: marketing hype often exceeds actual capability; AI agents still depend on user-set preferences. 6. Researchers caution that “agentic” is being used loosely; concept has existed in academia for decades. 4. Amendments Planned for Plant Variety Act (PPV&FRA) The story so far: * Centre plans amendments to PPV&FRA Act; stakeholder consultations underway. Key points: 1. Proposed changes to definition of “variety needs” & “combination of genotypes”; aligning with draft Seeds Bill 2019. 2. Discussions include revising definition of “breeder” to include public/private sector institutions. 3. Importance of trait testing under DUS guidelines is being stressed. 4. Concerns: misuse of DUS tests for registering community-developed seeds under private names. 5. Farmers fear monopolisation of seeds & loss of community control. 6. Groups demand mandatory registration of all community-developed seeds to protect collective rights.

Pre & Mains Notes

1. Solar Storms & Auroras What happened * Solar storms caused auroras to appear unusually far south in the Northern Hemisphere. * Auroras occur when charged solar particles interact with Earth’s atmosphere. Why now * Sun is in the peak phase of its 11-year activity cycle. * Multiple recent coronal mass ejections increased geomagnetic activity. Effects * Mostly visual phenomenon, but strong storms can disrupt power grids, satellites, radio and air traffic control. * Historic example: 1859 Carrington Event caused telegraph fires. 2. US Stops Minting Pennies What happened * US Mint produced its last batch of pennies after 232 years. * Production ended due to rising minting costs and reduced utility. Why discontinue * Cost of minting (3.69 cents) exceeds value (1 cent). * Digital payments and inflation reduced demand. What next * About 250 billion pennies remain in circulation. * Existing pennies continue as legal tender. 3. Ricin Toxin Alleged Terror Plot Case details * Gujarat ATS arrested three men accused of trying to produce ricin. * They allegedly planned attacks and surveyed multiple sites. About Ricin * Derived from castor seeds. * Highly potent; 1 mg can be lethal. * Prevents protein synthesis in cells, causing multi-organ failure. Challenges * Hard to detect early due to delayed symptoms. * No antidote; treatment is only supportive. Weaponisation history * Considered in World War attempts but difficult to stabilise. * Used in 1978 in the killing of Bulgarian writer Georgi Markov. 4. Tamil Nadu’s Transgender Healthcare Reforms Why important * Transgender persons face discrimination, lack of trained providers, and exclusion from public health schemes. TN’s initiatives * Gender-affirming surgeries available since 2008. * Transgender Welfare Board (2008) and Protection of Rights Act services. * Training of Gender Guidance Clinics. * Inclusion of transgender care under public insurance (CMCHIS-PMJAY). * Removal of income cap for insurance; simplification of documents. Impact * Over 5,200 individuals enrolled under schemes. * More than 600 gender-affirming surgeries funded. Remaining challenges * Need for comprehensive primary-to-tertiary care. * Better grievance systems and mental health services. * Need for accountable, trained facilities. 5. Draft Seeds Bill, 2025 Key provisions * Replaces Seeds Act, 1966 and Seeds Control Order, 1983. * Regulates quality of seeds and planting materials. * Ensures access to high-quality seeds at affordable prices. Enforcement * Minor violations decriminalised. * Strong penalties retained for serious offences. * Seed dealers required to register with State government. Concerns * Farmer unions fear bill favours private seed companies. * Demands for wider consultation. Industry view * Seen as modernization of seed regulation. 6. Hepatitis A and UIP Inclusion Why reconsider Hepatitis A * Growing outbreaks in multiple States. * Fewer children exposed early; immunity gaps increasing. * Acute liver failure in adults rising. Vaccine availability * Safe, long-lasting indigenous vaccines exist. * Protection lasts 15–20 years; often lifelong. Epidemiology * Hepatitis A now affects older groups who face more severe disease. * Outbreaks linked to sanitation lapses and antibody decline. Why inclusion makes sense * High disease burden. * Cost-effective control compared to other diseases. * Existing infrastructure allows easy rollout. * Aligns with UIP’s evidence-based phased expansion.

Pre & Mains Notes

1) Bihar Elections: How Exit Polls Are Conducted What Happened? Exit polls were conducted during the final phase of the Bihar elections. These polls estimate how people voted based on interviews taken as voters exit polling stations. Why It Matters? Exit polls influence public perception before results and help understand voter behaviour, turnout patterns, and election trends. Data Point Exit polls in India date back to 1957. Agencies are mandated by the ECI to release poll results only after voting in all phases is complete. Impact Exit polls are not always accurate. Smaller, more representative samples often outperform larger random samples. 2) What’s at Stake in Iraqi Parliamentary Polls? What Happened? Iraq held parliamentary elections with 329 seats at stake and unusually low voter enthusiasm. Why It Matters? The election is crucial for Iraq’s political stability, economic recovery, and managing U.S.-Iran tensions. The next government must also deal with Iran-backed militias. Impact The elected parliament will pick a president and prime minister, shaping Iraq’s governance for years. 3) Discord Between Supreme Court & Centre over Tribunals What Happened? The Supreme Court heard petitions challenging the Tribunals Reforms Act, 2021, triggering sharp exchanges with the Centre. Why It Matters? Tribunals impact judicial independence. The Centre’s move to reintroduce provisions struck down earlier has raised constitutional concerns. Impact Long delays and vacancies make tribunals “virtually defunct”, affecting dispute resolution efficiency. 4) Why Do Astronauts Wear Pressurised Suits? Why It Matters? Without atmospheric pressure, bodily fluids can boil, lungs can expand dangerously, and death can occur in minutes. Data Point Gaganyaan astronauts will use Russia’s Sokol KV2 suit, used in over 128 Soyuz missions. Impact Pressurised suits ensure survival during rapid decompression, fire, extreme heat, or cabin pressure failure. 5) What Do Forensic Experts Do After Blasts? What Happened? Forensic teams examined a major explosion near Delhi’s Red Fort, collecting samples within 30 minutes. Why It Matters? Blast forensics help determine cause: accident or intentional attack; using evidence analysis, heat patterns, chemical traces, and device remnants. Data Point Experts use tests like laser-based scene mapping, flashpoint testing, DNA tests, and thermo-chemical examination. Impact Multiple forensic divisions must collaborate to identify the attacker, reconstruct events, and present evidence in court. 6) Why India’s Road Safety System Keeps Failing What Happened? Supreme Court took note of two mass-casualty crashes (Rajasthan & Telangana), highlighting systemic failures. Why It Matters? - India has one of the world’s highest road fatalities — 1.7 lakh+ deaths in 2023. - Many states have no structured training, weak enforcement, poor road engineering, and no trauma response systems. Impact Crash deaths remain high because survival depends on post-crash care, not just prevention. 7) Tuberculosis Incidence Falling in India: WHO Report What Happened? India saw a 21% annual decline in TB incidence from 2015–2024, one of the best global performances. Why It Matters? India accounts for a major share of global TB cases; rapid decline is crucial for global elimination goals. Data Point * TB incidence: 237 → 187 per lakh * Treatment coverage: 53% → 92% * Missing cases: 15 lakh → <1 lakh * TB mortality: 28 → 21 per lakh Impact India’s TB Mukt Bharat Abhiyan has screened 19 crore people, detecting 24.5 lakh TB cases, accelerating elimination.
