• Security: NATGRID now processes 45,000 queries monthly and links 21 database categories; facial recognition carries 15% false-positive rate.
• Climate: India's absolute emissions rose to 3.35 Gt CO2e in 2024 despite hitting the 50% non-fossil capacity target ahead of schedule.
• Science: Thwaites Glacier's fracture length doubled from 165 km (2002) to 335 km (2022); full collapse could raise sea levels by 65 cm.
• Governance: DGMS (Directorate General of Mines Safety) celebrated its 125th Foundation Day. Census 2027 will be India's first fully digital census.
• Technology: ISRO launched EOS-N1 (Anvesha), a hyperspectral Earth observation satellite, on PSLV-C62.

NATGRID (National Intelligence Grid) is expanding access from central agencies to state police at the Superintendent of Police rank.

• Database categories linked: 21, covering travel records, financial transactions, telecom data and identity documents.
• Processing volume: Approximately 45,000 queries monthly as of January 2026.
• NPR integration: Now links to the National Population Register covering 119 crore residents.
• GANDIVA: An AI tool that reduces the time to link a suspect to data from days to minutes.
• Concerns raised: NATGRID operates through executive orders without a statutory framework. About 15% false-positive rate in facial recognition raises wrongful detention risks. Analysts argue parliamentary oversight is needed.
• Context: The Personal Data Protection Act's absence until 2023 (Digital Personal Data Protection Act 2023 was passed) meant NATGRID operated without a data rights framework for years.

India achieved two of its Paris Agreement targets ahead of schedule but absolute emissions continue to rise.

• Emissions intensity reduction: 36% by 2020. Updated target: 45% by 2030 (from 2005 baseline). Target achieved early.
• Non-fossil capacity: 50% of installed electricity capacity achieved. Target (40 to 50%) met ahead of 2030 deadline.
• Absolute emissions: Rose to 3.35 Gt CO2e in 2024. Absolute emissions growth is the challenge even as intensity falls.
• Coal dependency: 219 GW of coal-based power installed, contributing over 65% of electricity.
• Battery energy storage: Under 0.3 GWh installed against multi-gigawatt needs for grid stabilisation.
• Net-zero target: 2070.
• Paris Agreement context: India's NDC targets are intensity-based, not absolute. Prelims examiners test the distinction.

New research on Thwaites shows accelerating fracture growth.

• Location: West Antarctica, Amundsen Sea region.
• Size: Approximately the size of the United Kingdom.
• Fracture growth: The main fracture line doubled from 165 km in 2002 to 335 km in 2022. The rate of growth has accelerated.
• Sea-level risk: Complete collapse of Thwaites alone could raise global sea levels by approximately 65 cm. If it destabilises the West Antarctic Ice Sheet, the total rise could reach several metres.
• Warm water intrusion: Ocean warming causes warm water to penetrate under the glacier base, melting from below. This is faster and harder to reverse than surface melting.

The Census of India 2027 has several historic firsts.

• Number: The 16th Census of India, the 8th since independence.
• Two phases: House Listing (April to September 2026) and Population Enumeration (February 2027).
• Digital first: Data collected via mobile apps. Citizens can self-enumerate online 15 days before the enumeration period.
• Caste data: Electronic caste data collected for the first time since 1931. The last Social Economic and Caste Census (SECC) was in 2011 but was not a full census.
• Census-as-a-Service (CaaS): Datasets will be released in machine-readable formats for researchers and planners.
• Significance: Census data determines delimitation, welfare allocation and political representation. The delay from 2021 has created planning gaps.

The Directorate General of Mines Safety celebrated 125 years of operation in 2026.

• Established: 1902 (during British India).
• Headquarters: Dhanbad, Jharkhand.
• Ministry: Ministry of Labour and Employment.
• Mandate: Regulates safety in coal mines, metalliferous mines and oil mines.
• Legal basis: Mines Act 1952, which replaced earlier colonial mining legislation.
• Functions: Safety inspections, accident investigation and occupational health oversight.

ISRO launched the EOS-N1 satellite, named Anvesha, on the PSLV-C62 mission from Sriharikota.

• Type: Hyperspectral Earth observation satellite.
• Hyperspectral capability: Identifies materials across hundreds of narrow spectral bands, compared to multispectral satellites that use only a few broad bands. This allows identification of specific minerals, vegetation stress and military camouflage.
• Payloads: 18 co-passenger payloads carried alongside the primary satellite.
• Applications: Strategic surveillance, precision agriculture, urban mapping and environmental monitoring.
• Developer: ISRO, aligned with DRDO requirements for strategic surveillance.

The 1996 treaty expires in December 2026 and renewal discussions are active.

• Duration: 30 years from signing. Renewable by consent of both parties.
• Mechanism: Ten-day rotation formula for the dry season (January to May). Each side alternates priority access to Ganga flows.
• Allocation formula: Based on average flows recorded between 1949 and 1988 at Farakka.
• Emergency provision: Consultations triggered if flows drop below 50,000 cusecs at Farakka.
• Governance: Joint Committee with equal representation from both countries. Reviews every 5 years.
• Regulated at: Farakka Barrage in West Bengal. Monitored at Hardinge Bridge on the Bangladesh side.

NASA's IXPE mission studied polarisation patterns of X-rays from EX Hydrae, a white dwarf binary system.

• Distance: Approximately 200 light-years. Located in the constellation Hydra.
• Type: Intermediate polar, meaning the white dwarf has a moderate magnetic field that disrupts the accretion disc partially.
• Chandrasekhar limit: The maximum mass a white dwarf can have is approximately 1.4 solar masses. Above this, it collapses into a neutron star or explodes as a Type Ia supernova.
• Finding: Hot gas columns rise thousands of kilometres above the white dwarf surface at the magnetic poles, detected through X-ray polarisation by IXPE.

India became the first country to produce bio-bitumen at commercial scale.

• Institutions: CSIR-CRRI (Central Road Research Institute), New Delhi and CSIR-IIP (Indian Institute of Petroleum), Dehradun.
• Process: Pyrolysis converts agricultural residues (primarily rice straw) into bio-oil, which replaces 20 to 30% of conventional petroleum bitumen.
• Trial site: A 100-metre stretch on the Jorabat-Shillong Expressway (NH-40) in Meghalaya.
• Benefits: Reduces road construction cost, extends road service life and addresses stubble burning by creating an economic value for rice straw.
• Stubble burning link: Farmers burn rice straw because the residue has no value. Bio-bitumen creates demand for straw, potentially reducing burning.

Static linkage: Road infrastructure, stubble burning, circular economy.

• Weimar Triangle: France, Germany and Poland. Named after the city of Weimar where the first foreign ministers' meeting was held in 1991. Promotes European integration and coordinates EU foreign policy, especially on Russia and Eastern Europe.
• Victoria bushfires: Temperatures exceeding 40°C in January 2026. Victoria sits in southeastern Australia, bordered by New South Wales, South Australia, Tasman Sea and Southern Ocean.
