• Elections: Model Code of Conduct violations surfaced ahead of Bihar polls, reviving calls for a statutory MCC backed by the Representation of the People Act.
• Climate: the UNEP Emissions Gap Report 2025 warned that current national pledges put the planet on track for 2.3 to 2.5 degrees Celsius of warming.
• Science: India's first 500 km quantum key distribution network went live, developed by a Bengaluru-based firm under the National Quantum Mission.
• Defence: INS Ikshak, the third Sandhayak-class survey vessel built at GRSE Kolkata, was commissioned with over 80 per cent indigenous content.
• Space: Maharashtra became the first Indian state to sign an agreement with Starlink for low-Earth-orbit satellite connectivity.

GS area: Polity (elections, governance)

Alleged welfare cash disbursals coinciding with polling dates in Bihar reignited the long-standing debate on giving the Model Code of Conduct legal teeth.

• Origin: the MCC was first introduced during the 1960 Kerala Assembly elections. It was adopted nationally in 1962 with all-party consensus.
• Revision: the Supreme Court's 2013 judgment in the Subramaniam Balaji case prompted revisions that distinguished permissible welfare from impermissible freebies.
• Current status: the MCC is a voluntary code enforced by the Election Commission of India under its plenary powers in Article 324. It has no statutory backing.
• Reform proposal: constitutional experts recommend enacting a statutory Model Code of Conduct Act linked to the Representation of the People Act, 1951. That would give the ECI coercive enforcement powers beyond moral suasion.
• Article 324: vests superintendence, direction and control of all elections in the Election Commission. This is the existing constitutional anchor for MCC enforcement.

The Bihar case is a reminder that India's most consequential election-time rule operates entirely on political goodwill rather than law.

GS area: Environment (climate change, international conventions)

The United Nations Environment Programme released its 16th annual Emissions Gap Report, the most authoritative annual measure of the distance between national climate pledges and what science requires.

• Warming trajectory: current Nationally Determined Contributions (NDCs) put the planet on a path to 2.3 to 2.5 degrees Celsius of warming. The Paris Agreement target is well below 2 degrees, with efforts towards 1.5 degrees.
• Required reductions by 2035: emissions must fall 35 per cent for a reasonable chance of staying within 2 degrees. They must fall 55 per cent for 1.5 degrees.
• The 1.5 degree ceiling: the report concluded the 1.5 degree limit is likely to be breached by 2035 on current trajectories.
• G20 performance: only 9 of the 20 G20 members are on track to meet even their existing, inadequate NDCs.
• Finance gap: climate finance needs to triple by 2030 to meet stated goals. Developed nations have still not delivered the $100 billion annual pledge made at Copenhagen in 2009.
• UNEP: the United Nations Environment Programme is headquartered in Nairobi, Kenya. It was established in 1972 following the Stockholm Conference.

GS area: Internal security, Governance (narcotics)

The Directorate of Revenue Intelligence led Operation White Cauldron, dismantling a clandestine psychotropic drug factory in Valsad, Gujarat.

• Substance: Alprazolam, a benzodiazepine-class psychotropic substance commonly misused for sedation. It is controlled under the NDPS Act, 1985.
• Location: Valsad district, Gujarat.
• Value: seizure estimated at Rs 22 crore.
• Arrests: four individuals detained.
• DRI: the Directorate of Revenue Intelligence functions under the Central Board of Indirect Taxes and Customs, Ministry of Finance. It is India's premier agency for narcotics and commercial fraud intelligence.
• NDPS Act, 1985: the Narcotic Drugs and Psychotropic Substances Act classifies and penalises the manufacture, trade and possession of controlled substances.

GS area: Internal security, Economy (financial crime)

The Financial Action Task Force released a 340-page global guidance document expanding its asset recovery framework well beyond its original anti-corruption focus.

• New scope: the guidance now covers fraud, cyber offences and money laundering in addition to corruption-linked proceeds.
• India cases cited: the Agri Gold ponzi scheme (Rs 6,000 crore restored to victims), the IREO realty scam (Rs 1,800 crore attached), and the BitConnect cryptocurrency fraud (Rs 1,646 crore seized).
• FATF basics: established in 1989 by G7 nations to combat money laundering. Headquartered in Paris. Now has 40 member jurisdictions.
• India's status: India is a full FATF member since 2010. The Enforcement Directorate and Financial Intelligence Unit are India's primary FATF-linked bodies.
• Significance: asset recovery is the enforcement end of anti-money-laundering policy. The guidance gives national agencies a common methodology for tracing, freezing and returning criminal proceeds.

GS area: Science and Technology, Economy (telecom)

Maharashtra became the first Indian state to sign an agreement with Starlink Satellite Communications Private Limited, a SpaceX subsidiary.

• Technology: Starlink uses a constellation of satellites in low-Earth orbit at approximately 550 kilometres altitude.
• Advantage: low-Earth-orbit satellites deliver latency as low as 25 milliseconds compared to geostationary satellites orbiting at 35,786 kilometres and generating latencies of 600 milliseconds or more.
• Application: the agreement targets connectivity for rural and remote areas where terrestrial fibre infrastructure is absent.
• Regulatory context: Starlink received conditional approval from TRAI and the Department of Telecommunications under the Telecommunications Act, 2023.
• Significance for India: India aims to achieve universal broadband coverage under the National Broadband Mission. Satellite internet is positioned as the last-mile solution for geographically difficult terrain.

GS area: Science and Technology

QNu Labs Private Limited, a Bengaluru-based company, demonstrated India's first 500-kilometre quantum key distribution (QKD) network over existing optical fibre.

• Funding: the Department of Science and Technology under the National Quantum Mission supported the development.
• How QKD works: quantum key distribution uses photons to transmit encryption keys. Any attempt to intercept or eavesdrop on the quantum channel disturbs the photons, alerting both communicating parties to the intrusion instantly.
• Range significance: a 500-kilometre operational range over commercial fibre makes intercity secure communication feasible without dedicated infrastructure.
• National Quantum Mission: launched in April 2023 with an outlay of Rs 6,003 crore over eight years. It targets quantum computing, communication, sensing and materials.
• Strategic relevance: QKD offers post-quantum cryptographic security for defence communications, banking and critical infrastructure.

GS area: Defence (navy, indigenisation)

INS Ikshak was commissioned as the third ship of the Sandhayak class of Survey Vessels (Large), built by Garden Reach Shipbuilders and Engineers in Kolkata.

• Indigenous content: over 80 per cent, reflecting the Make in India push in naval shipbuilding.
• Specifications: 110 metres long, 16-metre beam, 3,300 tons displacement. Crew of 231 sailors and 20 officers.
• Primary role: hydrographic surveying of ports, harbours, channels and coastlines to produce nautical charts.
• Secondary capability: the ship converts into a 40-bed hospital vessel for Humanitarian Assistance and Disaster Relief missions.
• Speed: 18 knots.
• GRSE: Garden Reach Shipbuilders and Engineers is a Defence Public Sector Undertaking under the Ministry of Defence. It has built corvettes, frigates and fast patrol vessels for the Indian Navy.

GS area: Science and Technology (space science)

An international gravitational-wave collaboration detected event GW250114, produced by the merger of two black holes approximately 1.3 billion light-years from Earth.

• Black holes involved: each had a mass roughly 30 times that of the Sun.
• Detectors: LIGO (Laser Interferometer Gravitational-Wave Observatory) in the United States, Virgo in Italy, and KAGRA in Japan jointly confirmed the event.
• Hawking's Black Hole Area Theorem: the total event horizon surface area of a system of black holes can never decrease. The post-merger black hole in GW250114 had a greater event horizon area than the sum of the two pre-merger black holes, providing fresh observational verification of the theorem.
• Historical context: LIGO first detected gravitational waves in 2015, ten years before this event. The 2015 detection earned the Nobel Prize in Physics in 2017.
• Gravitational waves: ripples in spacetime caused by accelerating masses. Predicted by Einstein's General Theory of Relativity in 1916.

GS area: Defence (military exercises, border management)

The Indian Army's Eastern Command conducted Exercise Poorvi Prachand Prahar near Mechuka in Arunachal Pradesh, close to the Line of Actual Control with China.

• Participants: Army, Navy and Air Force formations in a joint tri-service exercise.
• Innovation: first deployment of light combat formations under the new "Raise and Save" model, which prioritises agility and rapid induction over heavy mechanised forces in high-altitude mountain terrain.
• Technology tested: AI-enabled Intelligence, Surveillance and Reconnaissance systems for real-time battlefield awareness at altitude.
• Location significance: Mechuka is in the Upper Siang district of Arunachal Pradesh, close to the McMahon Line and the disputed LAC.
• Context: India has been accelerating border infrastructure and forward deployment capacity in eastern Arunachal following the 2020 Galwan Valley standoff.

GS area: International Relations (US polity)

The United States government shutdown crossed 36 days, surpassing the previous record of 35 days set during the 2018 to 2019 Trump administration shutdown.

• Constitutional requirement: the US Congress must pass appropriations legislation before the fiscal deadline. A shutdown occurs when Congress fails to do so and the President does not sign a continuing resolution.
• Impact: approximately 1.4 million federal employees were furloughed or working without pay.
• Historical frequency: there have been 22 federal shutdowns since 1976. The first was under President Gerald Ford in 1976.
• India comparison: India does not have a shutdown mechanism. The President promulgates a Vote on Account allowing government expenditure to continue if the budget is not passed before the financial year ends.

• Operation Saber Tooth: Central Bureau of Investigation completed a coordinated action against online investment fraud networks operating across South-East Asia, recovering Rs 180 crore in crypto assets linked to Indian victims.
• PM KUSUM expansion: the Ministry of New and Renewable Energy extended the PM Kisan Urja Suraksha evam Utthaan Mahabhiyan scheme to cover 3.5 lakh additional agricultural pump sets with solar power in 2025-26.
• Tamil Nadu mangrove drive: Tamil Nadu's Forest Department reported planting 22 lakh mangrove saplings along the Pichavaram and Muthupet coasts under the MISHTI scheme, the Mangrove Initiative for Shoreline Habitats and Tangible Incomes.
