Climate Science Credibility Debate: Argo, CERES Data Shows Earth Energy Imbalance at 0.71 W/m²

IN-SPACe Releases Planned Re-entry Guidelines: Safety Threshold 1 in 10,000, Mandates Third-Party Liability Insurance

IN-SPACe has released new guidelines for planned re-entry of space objects, establishing a safety threshold of 1 in 10,000 risk to humans and mandating third-party liability insurance for private operators. This is crucial for India's human spaceflight mission Gaganyaan and the growing private space sector.

Climate Change Intensifies Clear Air Turbulence: 55% Rise in Severe CAT Over North Atlantic, DGCA Investigates Air India Incident

Climate change is making mid-flight turbulence, especially clear air turbulence (CAT), more frequent and severe. A 2023 study found severe CAT over the North Atlantic rose over 55% in four decades. For exam aspirants, this links climate change impacts to aviation safety, DGCA's regulatory role, and passenger safety protocols.

NALCO Sets Up Pilot Plants in Odisha for Rare Earth Recovery from Fly Ash & Red Mud - Critical Minerals Security

India moves towards self-reliance in rare earth elements (REE) critical for defence, electronics, and renewable energy. NALCO's indigenous pilot plants in Odisha recover REE from fly ash and red mud, reducing import dependence and advancing circular economy goals.

UK Met Office Forecasts Record El Nino >3°C; 2027 Likely Hottest Year on Record

The UK Met Office has forecast the strongest El Nino in over a century, with Pacific sea surface temperatures rising over 3°C above normal. This unprecedented event could make 2027 the hottest year globally, impacting global weather patterns including drier conditions in India and severe droughts in South America and the West Pacific.

ISRO Launches EOS-05: India's First Geosynchronous Earth-Imaging Satellite for Strategic & Disaster Monitoring

ISRO has successfully launched EOS-05, India's first earth-imaging satellite placed in geosynchronous orbit. Unlike polar-orbiting satellites, it can continuously observe the same area, making it invaluable for real-time disaster response (floods, cyclones, forest fires), agricultural monitoring, and strategic security applications. This marks a significant leap in India's space-based surveillance capabilities.

Candida auris Shows 90% Azole Resistance; Study Reveals Gene Duplication & Eagle Effect Challenging Antifungals

Fungal infections are rising due to global warming, with Candida auris emerging as a multidrug-resistant threat (30-40% mortality). New research from JNCASB and collaborators reveals that C. auris uses gene duplication (Erg11) and mutations (Fks1) to resist antifungals, and also exhibits the 'Eagle effect' where high drug doses paradoxically trigger compensatory chitin production, making the pathogen survive. This signals the end of the chemical arms race approach and calls for combination therapies and revised susceptibility testing limits.

India-Belgium Boost Defence Ties; SC Limits BCI Powers; WMO Warns Super El Niño; NASA Roman Telescope

Today's UPSC Key packs four high-yield stories: India-Belgium sign defence & semiconductor pacts, SC restricts Bar Council disciplinary powers to enrolled advocates only, WMO warns of a 'very strong' El Niño lasting till Feb 2027, and NASA’s Roman Telescope launched to study dark matter. Each has direct Prelims/Mains potential.

NPCIL Commences Fuel Loading at RAPP-8: 4th Indigenous 700 MWe PHWR in Fleet Mode

NPCIL has started initial fuel loading (IFL) at Unit 8 of Rajasthan Atomic Power Project (RAPP-8), a 700 MWe indigenous pressurised heavy water reactor (PHWR). This marks a major step in India's fleet-mode nuclear expansion, with commercial operation expected in 2026-27. For exams: understand PHWR technology, AERB's role, and the commissioning sequence (IFL → FAC → power generation).
