How cooler temperatures trigger a muscle-derived metabolic signal that sets off a whole-organism longevity program — a readable science feature worth opening.

Key Takeaways
- A specific muscle-derived metabolite increases in cold and triggers a systemic longevity program in nematodes.
- Cold-induced activation of a BH2-related metabolic network improves proteostasis and extends worm lifespan.
- The cold-triggered metabolic pathway and its longevity effects are conserved in human cells, suggesting translational potential.
