Space & Policy: India’s Department of Space issued a memo telling major ISRO centres not to routinely accept resignations or voluntary retirements from Group ‘A’ scientists on key missions like Gaganyaan, tightening exit rules as a reported brain drain tops 100 people. Antarctic Discovery: A-84’s iceberg breakaway exposed a long-buried seafloor where a robotic dive livestreamed ancient sponges, giant jellyfish, and possible new species in lightless depths. Climate & Risk: Scientists warn an “invisible river” of water vapour above the Amazon could weaken or vanish, with knock-on effects for rainfall; meanwhile Europe’s heatwaves and wildfires keep driving record temperatures and excess deaths, and attribution science is fueling a new legal fight. Health & Biology: A study links the RBFOX1 gene network to depression and related traits; separate work reports THC/CBD easing agitation in late-stage dementia, while researchers describe how a tiny Andean leaf-eared mouse survives extreme high-altitude conditions. Wildlife & Earth: Genomics suggests koalas crashed about 100,000 years ago (not just after humans arrived), and a new Congo monkey species with orange lips was identified. AI for Science: China launched a national scientific corpus infrastructure to feed AI-driven research with structured, domain-ready data.
