What ‘Immortal’ Jellyfish and Famously Old Tortoises Tell Us about Aging

Animals’ lifespans can be far shorter or much longer than those of
humans. Scientists are researching creatures such as “immortal”
jellyfish and long-lived tortoises and digging deep into genetic
codes to figure out why animals age—and what we can do to improve
longevity in humans. João Pedro de Magalhães, chair of molecular
biogerontology at the University of Birmingham in England, lays out
the state of aging science.   Recommended reading: Follow
