For the first time, scientists pinpoint the brain cells behind depression
Researchers have identified two distinct brain cell types — mood-regulating neurons and immune-related microglia — that function abnormally in people with depression, marking the first time scientists have pinpointed specific cellular culprits behind the condition. The findings, drawn from donated brain tissue analyzed with advanced genetic tools, reveal concrete biological disruptions in mood and stress pathways. The discovery strengthens the case that depression is a measurable neurological condition and could open new doors for targeted treatments.

Nuclear war at Ukraine-Russia border could trigger years of global climate disruption and radioactive fallout
A new study warns that even a limited nuclear exchange along the Ukraine-Russia border could trigger years of global climate disruption through smoke and particulate matter blocking sunlight, causing widespread crop failures and temperature drops. Radioactive fallout would spread far beyond the conflict zone, affecting populations across multiple continents. The findings underscore that the consequences of regional nuclear conflict are not regional at all — they are a global catastrophe in waiting.

This new brain-like chip could slash AI energy use by 70%
Researchers have developed a neuromorphic chip using modified hafnium oxide that replicates how biological neurons simultaneously process and store information. The design eliminates the costly data-shuttling that makes conventional AI hardware so power-intensive, delivering potential energy savings of up to 70%. As AI infrastructure strains global power grids, the breakthrough could prove critical to making large-scale AI systems sustainable.

NASA eyes September for Roman Telescope launch
NASA's Nancy Grace Roman Space Telescope is on track for an early September 2026 launch, nearly a year ahead of the agency's contractual deadline of May 2027. The wide-field observatory is designed to tackle some of astronomy's biggest questions, from dark energy to exoplanet detection. An earlier launch window signals strong progress in development and gives scientists more time with one of the most powerful telescopes ever built.

New study presents the eLTER Framework of Standard Observations for long-term, integrated environmental monitoring
Europe's fragmented approach to environmental monitoring gets a structured overhaul with the eLTER Framework of Standard Observations, a harmonized system designed to standardize long-term data collection across the continent. Published in *Earth's Future*, the framework establishes consistent protocols for tracking essential ecosystem variables within the eLTER Research Infrastructure network. The move addresses a longstanding barrier to cross-site comparability, making large-scale environmental analysis significantly more reliable and actionable.
