What: The Atal Pension Yojana (APY) completed 10 years in 2025 — launched on 9 May 2015 and made operational from 1 June 2015. It is a voluntary, defined-benefit pension scheme for workers in the unorganised sector, administered by the Pension Fund Regulatory and Development Authority (PFRDA) under the National Pension System (NPS) architecture. Eligibility: Indian citizens aged 18–40 years with a savings bank account. Importantly, income taxpayers have been ineligible to enrol since 1 October 2022. Subscriber base grew from 1.54 crore (March 2019) to 7.65 crore (April 2025), with a corpus of ₹45,974.67 crore. PFRDA is a statutory body under the PFRDA Act, 2013, chaired by Sivasubramanian Ramann and headquartered in New Delhi.

How: APY provides guaranteed pension amounts of ₹1,000 to ₹5,000 per month at age 60, depending on the subscriber’s age at joining and monthly contribution amount. The government co-contributes 50% of the subscriber’s contribution (or ₹1,000 per year, whichever is lower) for eligible subscribers who joined before 31 March 2016 — an incentive for early adoption. On the subscriber’s death, the corpus is returned to the nominee. The scheme specifically targets self-employed workers, domestic workers, and daily wage earners who lack access to formal pension benefits.

Why: APY is a high-frequency UPSC Prelims topic across GS-2 (social security, welfare schemes) and GS-3 (financial inclusion). Exam-ready facts: launch date (9 May 2015), operational date (1 June 2015), eligibility age (18–40), income taxpayer exclusion (1 Oct 2022), enrolment milestone (7.65 crore as of April 2025), corpus (₹45,974 crore), and administering body (PFRDA). Distinguishing APY from NPS (for government/private sector employees) and PM-SYM (Pradhan Mantri Shram Yogi Maan-Dhan, also for unorganised workers) is a common comparative MCQ pattern.

What: ITER (International Thermonuclear Experimental Reactor) is the world’s largest nuclear fusion project, being built in Cadarache, southern France. It aims to produce 500 MW of fusion power from a 50 MW input — a 10:1 energy gain ratio — demonstrating the scientific and technological feasibility of fusion energy. First plasma is targeted for 2033. India’s key contribution is the cryostat — a 30m × 30m vacuum vessel that houses the ITER Tokamak (the magnetic confinement chamber). India also built cryogenic pipelines (cryolines) carrying liquid helium at –269°C to maintain superconductivity in the magnets, in-wall shielding modules, and cooling water systems. Plasma inside the Tokamak is heated to 150 million °C — ten times hotter than the Sun’s core.

How: A Tokamak is a toroidal (doughnut-shaped) magnetic confinement device that uses powerful superconducting magnets to contain superheated plasma — the state in which hydrogen isotopes (deuterium and tritium) fuse to release enormous energy, replicating the process that powers the Sun. The concept originated in the Soviet Union in the 1960s. ITER is backed by 35 nations including the USA, China, Japan, Russia, the EU, India, and South Korea. The Central Solenoid — the world’s most powerful magnet — was completed and tested by the USA. India’s ITER participation is coordinated by the Institute for Plasma Research (IPR), Gandhinagar.

Why: ITER and nuclear fusion are growing UPSC GS-3 Science & Technology and energy topics with Mains essay potential. India’s specific contributions — cryostat (30m×30m), cryolines at –269°C, plasma heating to 150 million°C — are precision Prelims facts. The 500 MW output from 50 MW input ratio and 2033 first plasma target are exam-ready numbers. The Tokamak’s Soviet-origin, ITER’s multi-nation structure (35 nations), and IPR Gandhinagar’s coordination role are supporting static facts. ITER connects to India’s long-term clean energy ambitions and GS-3 themes of energy security and international scientific cooperation.

What: Garden Reach Shipbuilders & Engineers (GRSE), Kolkata — established in 1884 and led by CMD Commodore P.R. Hari — delivered INS Arnala, the first of eight Anti-Submarine Warfare Shallow Water Crafts (ASW SWCs), to the Indian Navy at L&T Shipyard, Kattupalli, Tamil Nadu. The vessel measures 77.6 m × 10.5 m and uses Diesel Engine-Waterjet propulsion. It carries approximately 88% indigenous content, reflecting the public-private partnership between GRSE and L&T. INS Arnala is named after the Arnala fort island off Vasai, Maharashtra. The Indian Navy’s Chief of Naval Staff (CoNS) is Admiral D.K. Tripathi (Indian Navy founded: 1950).

How: ASW SWCs are specialised vessels designed for Anti-Submarine Warfare (ASW) in littoral (shallow, coastal) waters — an environment where larger destroyers and frigates cannot operate effectively. INS Arnala’s missions include underwater surveillance using sonar systems, Search and Rescue (S&R) operations, and Limited Intensity Maritime Operations (LIMO) — small-scale engagements against non-state actors, smugglers, and intruders in coastal zones. The waterjet propulsion system provides high manoeuvrability in shallow waters compared to conventional propeller systems. GRSE received the Raksha Mantri Award 2022 for building the ‘most silent ship’ — a quality critical for ASW operations.

Why: GRSE, Indian Navy ship deliveries, and ASW capabilities are standard UPSC GS-3 (defence, indigenisation) and Prelims topics. Key facts: GRSE’s 1884 establishment, Kattupalli (L&T) delivery location, 88% indigenous content, 8-vessel series, Arnala fort naming origin, and waterjet propulsion. The ‘India’s first ASW SWC’ tag is a high-value Prelims identifier. The 88% indigenisation connects to Atmanirbhar Bharat in defence and India’s defence exports target (USD 5 billion by 2025) — strong Mains GS-3 content for answers on India’s defence industrial base.

What: Bengaluru-based Sarvam AI launched Bulbul v2, an advanced AI Text-to-Speech (TTS) model supporting 11 Indian languages: Hindi, Marathi, Punjabi, Odia, Tamil, Bengali, Telugu, Kannada, Malayalam, Gujarati, and English. It is an upgrade from Bulbul v1, which was released in August 2024. Key capabilities include fine-grained control over pitch, pace, and loudness; audio sample rates of 8–24 kHz; and smart normalisation for numbers, dates, and mixed-language text (code-switching). Sarvam AI offers India-first API pricing — making advanced multilingual voice technology accessible to Indian developers and enterprises at localised cost points.

How: TTS models convert written text into natural-sounding speech using neural network architectures trained on large volumes of annotated speech data. Bulbul v2’s smart normalisation addresses a specific Indian-language challenge: text often contains numerals, dates, abbreviations, and mixed Hindi-English (Hinglish) content that must be spoken naturally rather than letter-by-letter. The 8–24 kHz range covers both telephony (8 kHz) and broadcast-quality (24 kHz) use cases, making Bulbul v2 suitable for IVR systems, audiobooks, accessibility tools, and education platforms.

Why: India’s multilingual AI ecosystem — including Bhashini (government language platform), ULCA (Unified Language Contribution API), and private players like Sarvam AI — is an emerging UPSC GS-3 (AI, Digital India) and banking exam current affairs cluster. Sarvam AI and Bulbul v2’s 11-language coverage are testable current facts. The language list is exam-ready: Hindi, Marathi, Punjabi, Odia, Tamil, Bengali, Telugu, Kannada, Malayalam, Gujarati, English. This connects to India’s AI Mission (IndiaAI), the PM’s emphasis on mother-tongue technology access, and GS-2 themes of inclusive digital governance.

What: ‘The Johnson & Johnson Files’ is a book by Kaunain Sheriff M — National Health Editor of the Indian Express — published by Juggernaut Books (New Delhi). It investigates the ASR (Articular Surface Replacement) hip implant scandal involving DePuy Orthopaedics, a subsidiary of Johnson & Johnson (J&J). The ASR implants were introduced in 2003 and globally recalled in 2010 due to an alarmingly high failure rate and metal-on-metal toxicity — releasing cobalt and chromium ions into patients’ bodies. Approximately 4,700 Indian patients were affected. The book builds on a series of investigative reports published by the Indian Express in 2018–19.

How: In the United States, J&J settled with affected patients for USD 2.5 billion. In India, however, patients received little or no compensation — a stark contrast that forms the book’s central argument about India’s weak medical device regulation and patient protection framework. The scandal predated India’s Medical Devices Rules, 2017, which brought implants under formal regulatory oversight for the first time. The Central Drugs Standard Control Organisation (CDSCO) and its limitations in monitoring post-market device surveillance are central to the regulatory critique in the book.

Why: Books on contemporary governance failures are tested in UPSC Interview and GS-4 (ethics, accountability). The J&J scandal connects to GS-2 themes of health regulation, consumer protection, and the asymmetry between corporate accountability in developed vs developing countries. Medical Devices Rules 2017, CDSCO’s role, and post-market surveillance are GS-3 (pharmaceutical/medical sector regulation) Mains topics. Kaunain Sheriff M’s institutional affiliation (Indian Express) and the publisher (Juggernaut) are additional personality/book facts for competitive exam rounds.

What: Jochen Richard Mass (born 30 September 1946, Dorfen, Bavaria; died May 2025, Cannes, France; aged 78) was a German racing driver who competed in 105 Formula One Grands Prix between 1974 and 1982. His sole F1 victory came at the 1975 Spanish Grand Prix — a race stopped early due to an accident, making it a contested but officially counted win. He drove for teams including Team Surtees, McLaren, ATS, Arrows, and March, recording 1 win and 7 podium finishes across his F1 career.

How: Beyond F1, Mass had a distinguished endurance racing career. He won the 24 Hours of Le Mans in 1989 driving the Sauber C9, alongside co-drivers Manuel Reuter and Stanley Dickens. He accumulated 32 victories in the World Sportscar Championship — the second-highest tally of all time, behind only Belgian legend Jacky Ickx. He also won the European Touring Car Championship (ETCC) and the Spa 24 Hours in 1972, demonstrating versatility across racing disciplines.

Why: Obituaries of sporting legends are tested in banking and SSC exam GK rounds, particularly when connected to records and “firsts.” Mass’s 1975 Spanish GP win, his 1989 Le Mans victory (Sauber C9, with Reuter and Dickens), and his second-place all-time WSC wins record (32, behind Jacky Ickx) are precision facts for sports GK preparation. The Le Mans 24 Hours is a perennially tested event alongside its most famous winners — adding Mass to this list is useful for comprehensive motorsport GK coverage.
