🚨 SPACE SCIENCE | NASA MAVEN MISSION MARS MAY HAVE LOST ITS ATMOSPHERE TO SOLAR WINDS — NASA JUST FOUND NEW EVIDENCE 🔴🛡️ ━━━━━━━━━━━━━━━━━━━━━━━ ☀️ THE DISCOVERY NASA’s MAVEN mission detected the Zwan-Wolf effect at Mars — a magnetic phenomenon earlier observed only near Earth. 🔬 During a powerful solar storm (Dec 2023), charged particles compressed Mars’s ionosphere, causing local particle density to drop by nearly 50%. 🧠 WHY IT MATTERS ✅ Shows even planets without a global magnetic field can experience complex magnetic interactions ✅ Helps scientists understand how solar wind stripped away Mars’s atmosphere and water ✅ Important for studying planetary habitability and future Mars missions 📚 UPSC Focus: Prelims: Solar Wind • CME • Magnetosphere • Ionosphere • MAVEN Mains (GS3): Space Technology • Planetary Science 📥 SAVE • REVISE • SHARE @CurrentScenario — UPSC with current edge

🧬 Scientists decoded 18,000-year-old human DNA. The findings are reshaping our understanding of human evolution. Researchers analysed the largest ancient genome dataset ever: 📊 Highlights: 🔹 15,836 ancient DNA samples 🔹 Compared with 6,400+ modern humans 🔹 Published in Nature (2025) 🔍 Key Findings: 🩸 Blood Groups Evolving B blood-group genes increased over 6,000 years, while A declined. ☀️ Skin Adaptation Lighter skin traits spread in low-sunlight regions to improve Vitamin-D synthesis. 🌾 Diet Changed Human Genes Gluten-related genes increased after agriculture became widespread. 🦠 Ancient Disease Resistance A gene linked to HIV resistance existed long before HIV emerged. 🇮🇳 India Angle: South Asians carry ancestry from Iranian farmers, Steppe herders and ancient indigenous populations. ⚛️ DNA Dating Method: Carbon-14 dating based on radioactive decay. 📚 UPSC Relevance: GS-3: Genetics • Biotechnology • Carbon Dating GS-1: Human Evolution @CurrentScenario

━━━━━━━━━━━━━━━━━━━━━━━ 🏛️ WHY INDIA’S CITIES STILL LACK POWER 📌 GS-2 | Federalism | Urban Governance ━━━━━━━━━━━━━━━━━━━━━━━ The 74th Amendment (1993) gave constitutional status to Urban Local Bodies. But real financial and administrative power never followed. 📊 Reality Check: 🇮🇳 ULB tax revenue → only 0.3% of GDP 🇮🇳 Cities still depend on States for funds and staff ⚠️ Why are ULBs weak? • States retain major control • Weak mayors, stronger bureaucracy • Poor urban finance systems 💡 Result: India’s growth engines remain the weakest tier of governance. 🇨🇳 China empowered cities to build large-scale infrastructure. 🇮🇳 Indian cities still struggle with basic civic services. ✅ Way Forward: → Fiscal devolution → Stronger elected mayors → Urban governance reforms 🖊️ Mains Line: “Indian federalism must go beyond Centre–State relations to include empowered cities.” 📚 UPSC Focus: 74th Amendment | Fiscal Federalism | Urban Reforms 📥 READ • SHARE • REVISE @CurrentScenario — UPSC with current edge
