Yeast exposed to Mars-like stressors—including perchlorate salts and shock waves analogous to meteorite impacts—survived in part by assembling ribonucleoprotein condensates in their cells. Read now: https://t.co/EmytqIvRGb @labrajyaguru @rajgodhuli @riyaDhage2910 @iiscbangalore

An AI-powered satellite survey finds fewer than 600,000 wildebeest in the Great Migration—half the long-cited 1.3M—showing how new monitoring tools refine population estimates. In @Mongabay: https://t.co/9sl5AHxarE In PNAS Nexus: https://t.co/ITtUukFzGZ

Postwar Britain’s natural experiment finds maternal sugar access in pregnancy linked to higher education & lower adult BMI—effects stronger in those genetically prone to higher sugar intake. In @TechExplorist: https://t.co/gFJ0X82N07 In PNAS Nexus: https://t.co/MMlkuhhIrQ

How is AI changing the future of chemistry? Discover how machine learning is advancing molecular design, reaction prediction, and materials development in the PNAS Special Feature Machine Learning in Chemistry: https://t.co/zOj4tMFtGx

In this week’s Advanced Articles: We delve into how dialogues with large language models reduce conspiracy beliefs even when the AI is perceived as human, examine how activation of orexin neurons changes reward-based decision-making strategies, and more: https://t.co/YZx4pQjk0T

Researchers asked people to indicate where on their bodies they felt the urge to move and where they felt pleasure when listening to music. The urge to move was felt more in the head, arms, and legs, and pleasure more in the chest and abdomen. Read now: https://t.co/9fumbrr25V
