1. Suncatcher: Google moonshot to move data centres to space What happened * Google announced Project *Suncatcher*, a long-term research initiative to explore solar-powered data centres in space by 2027. Issue raised * Rising energy, water and climate costs of terrestrial data centres powering AI and cloud computing. Current context * Data centres face criticism for fossil fuel dependence, water depletion and vulnerability to outages and disasters. * Advances in rockets, satellite tech and space computing have reduced launch and experimentation costs. Way forward / Why it matters * Space-based data centres could offer constant solar energy and data sovereignty advantages. * Challenges include latency, cybersecurity, maintenance, costs and Outer Space Treaty constraints. 2. N-power Bill introduced; permits private operators, limits supplier liability What happened * Government introduced the Nuclear Power Bill in Lok Sabha to allow private participation in nuclear power and cap supplier liability. Issue raised * Existing Civil Liability for Nuclear Damage Act discouraged private and foreign investment due to high supplier liability. Current context * India aims to expand nuclear energy for clean baseload power to meet climate and energy security goals. * Small Modular Reactors and advanced nuclear technologies require private sector involvement. Way forward / Why it matters * Bill aligns India with global nuclear liability norms. * Raises concerns on safety, accountability and public trust in nuclear expansion. 3. Does India need to upgrade its biosecurity measures? What happened * Experts flagged gaps in India’s biosecurity framework amid rapid advances in biotechnology. Issue raised * Existing systems focus more on biosafety than preventing deliberate misuse of biological agents. Current context * India is signatory to the Biological Weapons Convention. * Increased access to biotech tools raises risks from non-state actors, lab leaks and bio-terrorism. Way forward / Why it matters * Need for unified national biosecurity framework integrating health, agriculture, environment and security. * Strong biosecurity is critical for public health, livestock safety and national security.

Lunacrete concrete for the Moon What happened • Scientists developed lunar concrete using moon regolith for future lunar habitats. Issue raised • Conventional cement requires water which is scarce on the Moon. Current context • Lunacrete uses regolith with sulphur or microwave heating. • Can withstand extreme lunar temperatures. • Important for long term lunar missions by US and China. • Part of space habitation and extraterrestrial infrastructure. 5. Big Shot Nubian ibexes in Negev desert What happened • Photograph captured Nubian ibexes navigating steep rocky terrain in Israel’s Negev desert. Issue raised • Survival of desert species in fragile arid ecosystems. Current context • Nubian ibex is adapted to extreme desert environments. • Highlights biodiversity in West Asian deserts. • Relevant for conservation and climate adaptation studies.

PYQ related to Volcanism with detailed explanation.

Revise with CSEWhy😊 Topic : Volcanism 1. Definition • Volcano: Opening releasing magma, gases and pyroclasts due to internal pressure. 2. Key Terms • Magma: Molten rock below • Lava: Molten rock on surface • Vent: Eruption pathway • Crater: Summit depression • Caldera: Large collapsed depression • Fissure: Linear crack • Pyroclasts: Solid ejecta • Hotspot: Stationary mantle plume • Volcanic gases: Water vapour, CO₂, sulphur compounds, nitrogen compounds 3. Types of Lava • Basaltic: Low silica, fluid, gentle • Andesitic: Medium silica, moderate • Rhyolitic: High silica, viscous, explosive 4. Volcano Types with Examples • Shield: Broad, basaltic. Example Mauna Loa • Composite: Layered, explosive. Example Mt Fuji • Cinder cone: Pyroclastic. Example Paricutin • Lava dome: Viscous dome. Example Mt Pelee dome • Fissure: Linear cracks. Example Deccan Traps • Caldera: Collapse. Example Yellowstone 5. Distribution • Ring of Fire about 75 percent of volcanoes • Divergent boundaries: Iceland • Convergent boundaries: Andes, Japan • Hotspots: Hawaii, Reunion 6. Some more facts • Deccan Traps are fissure flood basalts • Andesite forms at subduction zones • Hotspots remain fixed, plates move • Higher silica increases viscosity and explosiveness • Volcanic soils are highly fertile • Volcanoes emit sulphur dioxide and nitrogen oxides affecting climate • Sulphur aerosols cause short term global cooling • Most active volcanoes occur at convergent boundaries.

1) GPS Jamming & Spoofing Incidents Rising in Aviation What Happened * Global aviation is reporting a sharp rise in GPS/GNSS interference—especially around conflict zones (Middle East, Eastern Mediterranean, Arctic) and recently near major Indian airports including Delhi. * These disruptions affect aircraft navigation, timing and routing. Issue Raised * Jamming: Overpowering a GNSS receiver with strong radio interference, making navigation temporarily unusable. * Spoofing: Deliberately sending counterfeit GNSS signals to mislead the aircraft about position/time. Current Context * MoCA informed Parliament of repeated interference cases around the Delhi airport. * Airlines worldwide reported a 200% rise in GPS signal-loss events (2021–24). * Spoofing is becoming a major safety risk, capable of causing navigational confusion in cockpit systems. Why it Matters for India / UPSC * Safety concerns for civil aviation. * Need for redundancy systems & protected navigation infrastructure. * GNSS vulnerabilities impact national security and aviation reliability. 2) How Mangroves’ Cells Help Plants Survive Saltwater What Happened * New study (Current Biology) reveals specific cell-level traits that allow mangroves to tolerate high salinity. Issue Raised * Saltwater kills most terrestrial plants, but mangroves survive due to specialised cellular adaptations. Current Context * Scientists analysed 34 mangrove species across 17 plant families: * Smaller & more compact cells * Thicker cell walls for mechanical strength * Specialised epidermal cells for salt expulsion * Waxier roots in some species to exclude salt * Mangroves also excrete salt through leaf glands. Why it Matters for India / UPSC * Helps develop salt-tolerant crops (critical under climate change & sea-level rise). * Mangrove ecosystems protect coasts, support biodiversity, and prevent erosion. 3) Sacred Claims: The Preah Vihear Temple Dispute (Thailand–Cambodia) What Happened * Ongoing border tensions over the Preah Vihear temple, a UNESCO World Heritage site, revived by recent political statements. Issue Raised * Dispute centres on ownership of the plateau surrounding the temple, though ICJ had already ruled. Current Context * Temple built by Khmer kings (9th–12th century), dedicated to Shiva. * ICJ rulings: * 1962: Temple belongs to Cambodia. * 2013: Cambodia also owns the entire promontory; Thailand must withdraw security forces. * Border clashes have occurred intermittently, sometimes killing dozens and displacing thousands. Why it Matters for India / UPSC * Example of international boundary disputes + role of ICJ in conflict resolution. * Illustrates how colonial-era cartography fuels modern tensions. * Important for GS-1 (World Heritage), GS-2 (IR), and Essay.
