6 reportsEcology and microbiology provide the main comparison, while cell biology tests the interpretation. Reports address how living systems are studied and how cells regulate function, comparing competing models without treating agreement as proof of mechanism.
Shannon Lucid Set a Human Spaceflight Record on Mir
Shannon Lucid spent 188 days aboard Russia's Mir, tending life-science experiments and helping NASA understand the operational, psychological, and cultural demands of long-duration spaceflight.
A Fire Amoeba Sets a New Heat Limit for Complex Life
A NASA-supported study identifies an amoeba from California hot springs that reproduces at 63°C, remains active at 64°C and can recover after brief exposure to temperatures approaching 70°C.
Anthropic Blocks Claude Use in Suspected Bioweapons and Espionage Cases
Anthropic has reported five incidents where its Claude AI model was used in research with potential biological weapons implications and uncovered a Russian cyber operation using the same technology, raising urgent questions about AI safety and oversight
Microgravity Slows Digestion for Astronauts on the ISS, Study Finds
A new analysis of blood samples from 52 astronauts aboard the International Space Station reveals that microgravity alters gut function, slowing digestion and changing microbial activity in ways not fully explained by diet alone
Automated Mini-Labs Expand Space Station Research With Less Crew Time
Redwire's ADvanced Space Experiment Processors (ADSEPs) are enabling the International Space Station to run complex biological and materials science experiments with minimal astronaut involvement, advancing pharmaceutical and fundamental research in microgravity
Simulations Map Phase Separation in Disordered Protein Condensates
Researchers used computer simulations to analyze how intrinsically disordered proteins with prion-like domains cluster and undergo phase separation, revealing distinct regimes and highlighting challenges in measuring critical parameters
