Age-related decline of chaperone-mediated autophagy blunts the regenerative capacity of muscle stem cells, partly due to impaired glycolytic shift required for normal stem cell expansion.

Climate change can alter when and how animals grow, breed, and migrate, but it is unclear whether this allows populations to persist. This global study shows that shifts in seasonal timing are key to helping vertebrate species maintain population growth under global warming.

Humanity’s Last Exam, a multi-modal benchmark at the frontier of human knowledge, is designed to be an expert-level closed-ended academic benchmark with broad subject coverage.

Gram-negative bacteria use a multiprotein complex, LptB₂FGC, to transport lipopolysaccharides (LPS) to the outer membrane. Here, Fiorentino et al. present cryo-EM structures of the complex from Pseudomonas aeruginosa, revealing species-specific features and providing insights into LPS transport mechanisms.

Motion vision in many animals is split into pathways for bright (ON) and dark (OFF) edges, driven by luminance changes. Here the authors show how in Drosophila color selectively contributes to ON-motion, enhancing detection of saliently colored objects.
