The case for space as a model of accelerated aging

Astronauts in space experience accelerated aging, offering unique insights into how aging works and potential interventions to slow it.

Published in Nature Aging, this paper from Buck Institute makes the case that spaceflight recapitulates aging hallmarks on accelerated timelines through microgravity, radiation, circadian disruption, and isolation. It proposes astronauts as uniquely informative models for advancing healthspan research.
