Pre & Mains Notes

1. Indian Army Upgrading Air Defence Radars • What happened: The Army is procuring 45 Low Level Light Weight Radars (Enhanced), 48 Air Defence Fire Control Radars (ADFCR-DD), and 10 Low Level Light Weight Radars (Improved) to plug gaps in its AD network. • Why relevant: Operation Sindoor (May 2024) exposed vulnerabilities when swarms of Pakistani drones infiltrated Indian airspace; highlighting new-age security threats. • Data point: ADFCR-DD can detect, classify, and transmit target data of small drones up to 10 km away. • Impact: Strengthens India’s defence against low-cost UAVs, deters asymmetric warfare tactics, and supports Atmanirbhar Bharat in defence R&D. • Exam hook: GS-III (Defence Technology, Security Challenges); Prelims (Radar Systems). 2. Scientists Discover Ant That Gives Birth to Two Species • What happened: Research shows Messor ibericus queens can produce offspring of a different species (Messor structor), overturning traditional ideas of species inheritance. • Why relevant: Challenges classical biology assumption that progeny always belong to the same species → opens debates on hybridisation, evolution, and genetics. • Data point: Study published in Nature; ~10% of eggs laid by Messor ibericus carried mitochondrial DNA of Messor structor. • Impact: Offers new insights into speciation, evolutionary biology, and potential analogies in higher organisms—broadening scientific understanding. • Exam hook: GS-III (Science & Tech – Genetics, Evolution); Essay (Science changing perception of life). 3. Sarnath: From Buddha’s First Sermon to Emblem of Republic • What happened: ASI will install a new plaque crediting Babu Jagat Singh (1787–88) for preserving Sarnath, ahead of a UNESCO evaluation for World Heritage listing (2025–26). • Why relevant: Sarnath is where Buddha delivered his first sermon (~528 BCE), later influencing India’s national emblem (Ashokan Lion Capital). • Data point: Excavations by Cunningham (1835–36) and Friedrich Oertel (1904–05) uncovered 476 artefacts and 41 inscriptions in one season. • Impact: Correcting colonial narratives; strengthens India’s civilizational identity and global Buddhist diplomacy. • Exam hook: GS-I (History & Culture), GS-II (UNESCO heritage diplomacy). 4. EU–India Strategic Partnership Upgrade • What happened: EU unveiled a “New Strategic EU–India Agenda” covering trade, tech, security, defence, and climate; FTA negotiations with India ongoing. • Why relevant: Comes amid EU concerns over India’s military ties with Russia, yet India is termed a “crucial partner” in balancing Indo-Pacific geopolitics. • Data point: The 14th round of India–EU FTA talks is scheduled for October 2025; aim is to seal trade deal by year-end. • Impact: A deeper EU–India axis could counterbalance China, diversify supply chains, and expand India’s global trade footprint despite Russia-related frictions. • Exam hook: GS-II (International Relations: India–EU), GS-III (Economy: Trade Agreements).
