Gene activity clocks estimate lifespan across species, matching epigenetic tools

AI Summary

Researchers have developed molecular clocks that estimate lifespan and molecular age across various mammalian species using epigenetic analysis. This study, analyzing over 11,000 samples, could support targeted longevity interventions.

Molecular clocks that can provide accurate estimates of both molecular age and lifespan across multiple mammalian species and tissue types are presented in an article published in Nature this week. An analysis of more than 11,000 human, rodent, and primate samples reveals conserved signatures of aging. This framework may aid the development of targeted interventions to improve longevity.
