Cold activates a chemical network that extends lifespan in worms

Experiments in worms found that boosting production of a cold-induced molecule in muscle promoted longevity and reduced protein clumping at normal or elevated…Experiments in worms found that boosting production of a cold-induced molecule in muscle promoted longevity and reduced protein clumping at normal or elevated temperatures.
