Nature Study: Cold Activates BH2 Metabolic Network That Extends Worm Lifespan
The Facts
- A paper by Lee et al. in Nature (2026) reports a metabolic switch that activates a longevity program in response to moderately low temperature. Nature only
- The paper is titled 'Cold activates a BH2 metabolic network promoting longevity and proteostasis'. Nature only
- Nature's accompanying news-and-views piece states that worms live longer in cool conditions thanks to a muscle-derived molecule. Nature only
- Prior research cited by Nature shows that moderately low ambient temperature or lowered core body temperature can extend lifespan in organisms ranging from nematode worms to mice. Nature only
Context
A Nature commentary highlights a new study by Lee et al. identifying a metabolic switch through which moderately low temperature activates a longevity program in nematode worms. The commentary says a muscle-derived molecule is involved, and the paper links a BH2 metabolic network to longevity and proteostasis.
The available text is a paywalled excerpt, so details of methods, results and the molecule's identity are not provided.
