AI Safety & Policy: OpenAI chief scientist Jakub Pachocki argues AI development should slow and governments must coordinate, while former Anthropic researcher Jacob Coxon warns systems could become hard to control; meanwhile Trump dismisses extinction fears, framing the real risk as losing the AI race to China. Bioweapons Misuse: Anthropic says it blocked multiple Claude attempts tied to potentially dangerous biological research, highlighting the fine line between legitimate science and weaponizable work. Underwater Energy: Chinese researchers report perovskite solar cells can power submerged devices at 10 meters depth for years, enabling longer-lasting marine sensors. Mars Habitability Clue: NASA’s Perseverance finds white clay (kaolinite) in Jezero Crater, pointing to long-lasting warm, wet conditions. Health & Environment: Florey Institute links prenatal exposure to the plasticiser DEHP with epigenetic changes tied to higher autism/ADHD symptoms; separate work finds scalding hot drinks may raise oesophageal cancer risk. Tech for Security & Forensics: A new model (VIB-NER) improves detection of unseen threat terms in cyber reports, and another system identifies phone models from audio recordings. STEM & Institutions: Liberty Science Center breaks ground on a $40m expansion; Ontario Science Centre faces science-department layoffs; UAB buys part of Southern Research campus to expand research space.
