Continuing the recent run of interesting observations arising from the ability to assess epigenetic age, researchers here show that a hibernating species shows no uptick in epigenetic age over the period of hibernation. The metabolism of hibernation has been a topic of minor interest for some years in the context of aging and mechanisms of aging. The metabolic state of hibernation seems favorable in many of the same ways that are observed in states like calorie restriction, but perhaps for distinct reasons.
