In nematodes, a metabolite induced by the cold links low temperatures to a body-wide signal that promotes longevity. This signalling system is also seen in human cells.

Temperature is a crucial factor that affects ageing and lifespan. For instance, a moderately low ambient temperature or a lowered core body temperature can extend lifespan in various organisms, from nematode worms to mice1. Writing in Nature, Lee et al.2 identify a metabolic switch that activates a longevity program in response to moderately low temperature.
