UCLA-led study shows that aging slows to a crawl when the animals hibernate

“Our results from different statistical approaches reveal that epigenetic aging essentially stalls during hibernation,” said lead author Gabriela Pinho, who conducted the study as a UCLA doctoral student advised by Daniel Blumstein and Robert Wayne, professors of ecology and evolutionary biology. “We found that the epigenetic age of marmots increases during the active season, stops during hibernation and continues to increase in the next active season.”
