• Urban India: Only 37% of urban residents have easy access to public transport; the infrastructure gap is 1.65 lakh buses short of what cities need.
• Political finance: Ruling party received over 80% of reported corporate donations in FY25; electoral trust donations tripled after electoral bonds were struck down.
• Rural connectivity: PMGSY completes 25 years; its fourth phase targets 25,000 habitations over 62,500 km of new roads by 2029.
• Science: IISc's magnetic nanobots show early promise for targeted cancer therapy; Dr Ambarish Ghosh wins the 2025 New York Academy of Sciences Tata Sons Prize.
• History: The Communist Party of India marks its centenary; founded December 26, 1925 at Kanpur.

India's cities house roughly 36% of the national population in 2024. That share is projected to cross 50% in the 2050s. The infrastructure is not keeping pace.

• Public transport access: Only 37% of urban residents live within easy reach of a bus stop or metro station. The majority of city dwellers rely on private vehicles or informal transport.
• Bus fleet gap: Indian cities need approximately 2 lakh buses to meet demand. The operational fleet stands at around 35,000. The gap is roughly 83%.
• Economic weight: Urban India contributes 65 to 70% of national GDP. Congestion and poor connectivity impose a direct cost on that output.
• Transit-oriented development (TOD): TOD is an urban planning model that concentrates housing, offices and retail within walkable distance of transit nodes. Planners advocate it as the most cost-effective way to reduce car dependence.
• Municipal bonds: Indian cities are legally permitted to issue bonds for infrastructure financing. Take-up has been minimal because most urban local bodies lack the creditworthiness to attract investors.
• In-situ slum redevelopment: Upgrading slums at their existing location rather than relocating residents. Relocation breaks social networks and employment linkages; in-situ approaches retain them.

The urban bus shortage is not a surprise; it has been documented for over a decade. What has not happened is the fiscal architecture to fix it: robust property tax collection, transferable development rights and functional municipal bond markets.

The Supreme Court struck down the Electoral Bond Scheme in February 2024. The data on what followed is now becoming clear.

• Ruling party share: The ruling party received over 80% of total reported corporate political donations in FY25. Concentration of funding in the incumbent is a standard indicator of quid-pro-quo risk.
• Electoral trust surge: Donations routed through Electoral Trusts tripled after electoral bonds were scrapped. Electoral Trusts are registered legal entities that pool corporate donations and distribute them to parties; unlike electoral bonds, they require disclosure.
• Historical evolution: Corporate political finance in India moved from cash donations (banned in 2003) to Electoral Trusts (introduced 2013) to Electoral Bonds (2018 to 2024) and now back to Electoral Trusts as the primary formal channel.
• "Blind pool" proposal: Reformers propose routing all corporate donations through an independent constitutional body that would distribute funds proportionally to parties based on electoral performance. Neither donor nor recipient would know the other's identity.

The blind pool idea addresses the transparency problem but not the concentration problem. It does not cap total donations or equalise access to money across parties.

The Pradhan Mantri Gram Sadak Yojana was launched on December 25, 2000, on Atal Bihari Vajpayee's birth anniversary. It is now in its fourth phase.

• Scheme objective: PMGSY aims to provide all-weather road connectivity to eligible unconnected habitations. An all-weather road allows vehicle movement throughout the year, including the monsoon season.
• Cumulative progress: 8.25 lakh km of roads have been sanctioned. As of December 2025, 95% of the sanctioned length is complete.
• PMGSY-IV (2024 to 2029): The fourth phase targets connectivity to 25,000 habitations via 62,500 km of new roads.
• Technology tools: OMMAS (Online Management, Monitoring and Accounting System) tracks expenditure and progress. e-MARG is the management information system for road data. GPS-equipped vehicles monitor actual usage and condition.
• Funding: PMGSY is centrally sponsored. The Centre and states share costs; the ratio varies by category of state.

The Central Consumer Protection Authority imposed a penalty of Rs 11 lakh on a coaching institute for publishing misleading UPSC advertisements.

• CCPA: The Central Consumer Protection Authority was created under the Consumer Protection Act 2019. It can take suo motu cognisance of widespread harm to consumers and issue orders against false advertising.
• Misleading advertisement defined: Under the 2019 Act, a misleading advertisement is one that contains a false description, makes a false guarantee, or omits material information a consumer needs to make an informed decision.
• Digital and e-commerce coverage: The 2019 Act explicitly extends its protections to e-commerce and digital advertisements, a deliberate update from the 1986 Act which predated the internet.
• Coaching sector context: UPSC coaching institutes routinely advertise inflated success rates or claim unverified "toppers" associations. The CCPA action signals that these claims are legally actionable.

Village Defence Guards (VDGs) were launched in March 2022 by the Ministry of Home Affairs to augment security in conflict-affected areas.

• Composition: Each VDG group consists of up to 15 members drawn from ex-servicemen and trained civilians in the area.
• Remuneration: Group heads receive Rs 4,500 per month. Members receive Rs 4,000 per month. The payments come from the central government.
• Role: VDGs conduct day-and-night patrols and participate in search operations alongside security forces. They serve as a local intelligence and early-warning layer.
• Precursor model: The Salwa Judum in Chhattisgarh (2005 to 2011) was an earlier unofficial village defence experiment. The Supreme Court struck it down in 2011 (Nandini Sundar vs State of Chhattisgarh) as unconstitutional. VDGs are designed to be a formal, regulated alternative.

Researchers at the Indian Institute of Science (IISc), Bengaluru developed magnetic nanobots for targeted cancer therapy. The work earned Dr Ambarish Ghosh the 2025 New York Academy of Sciences Tata Sons Prize.

• Design inspiration: The nanobots are helical, modelled on bacteria that propel themselves by rotating flagella. The helix shape allows efficient movement through biological fluids.
• Guidance mechanism: External magnetic fields steer the nanobots through tissue to reach tumour sites. No internal power source is needed.
• Current stage: Validated on cell cultures and animal models. Human clinical trials have not begun.
• Therapeutic advantage: Targeted delivery means the drug or treatment reaches the tumour directly, reducing systemic toxicity compared with conventional chemotherapy.

India's primary market raised Rs 3.8 lakh crore through 701 IPOs in FY 2024-25, a record for a single year.

• IPO methods: A fixed-price issue sets the share price in advance. Book building, the dominant method in India, invites investors to bid within a price band; the final price is determined by demand.
• Investor categories in book building: Qualified Institutional Buyers (QIBs) receive up to 50% of shares. Non-Institutional Investors (NIIs) receive 15%. Retail Individual Investors (RIIs) receive 35%.
• SEBI oversight: SEBI sets the allotment norms, mandates the red herring prospectus and monitors for price manipulation. The surge in IPOs has prompted SEBI scrutiny of SME IPO quality.

The Communist Party of India was founded on December 26, 1925 at a congress in Kanpur. It is the oldest Marxist political party in India.

• Founders: M.N. Roy, S.A. Dange and others. M.N. Roy had already founded the Communist Party of Mexico and was in contact with the Comintern.
• Ideology: Marxism. The party aligned itself with the Soviet-led Communist International and campaigned for class struggle as the route to Indian independence.
• Peasant movements: CPI leaders organised the Tebhaga movement in Bengal (1946 to 1947), demanding that sharecroppers receive two-thirds rather than one-half of their harvest. They also led the Telangana armed uprising (1946 to 1951) against the Nizam of Hyderabad.
• Electoral milestone: E.M.S. Namboodiripad led the first elected Communist government in the world outside the Soviet bloc when the CPI won the 1957 Kerala Legislative Assembly elections.
• 1964 split: Disagreement over the Sino-Soviet dispute fractured the party. The faction closer to China's position formed the Communist Party of India (Marxist). The CPI remained Soviet-aligned.

Kilimanjaro is featured because of ongoing international coverage of its retreating ice cap, which is a standard climate change map item.

• Location: Northeastern Tanzania. It is a free-standing volcanic massif, not part of a mountain range.
• Height: 5,895 metres, making it Africa's highest peak and the world's tallest free-standing volcanic mountain.
• Volcanic structure: Three distinct volcanic cones: Kibo (5,895 m, the summit), Mawenzi (5,149 m) and Shira (3,962 m).
• UNESCO status: Kilimanjaro National Park is a UNESCO World Heritage Site.
• Ice cap loss: Kilimanjaro has lost more than 80% of its glacial ice since 1912. Scientists attribute the retreat primarily to reduced snowfall and sublimation driven by atmospheric warming.

Research on private jet travel entered policy discussions at the Loss and Damage forum. The carbon arithmetic is straightforward and prelims-testable.

• Emission quantum: A single private jet flight produces carbon emissions roughly equivalent to the total annual emissions of an average person in the developing world.
• Climate justice framing: The Loss and Damage mechanism adopted at COP27 (Sharm el-Sheikh, 2022) rests on the principle that those least responsible for emissions suffer the most. Private jet data makes that argument concrete.
• UNFCCC principle: The principle of Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC) recognises that countries (and implicitly individuals) have contributed differently to the problem and have different capacities to address it.
