What's this super-aging butterfly’s longevity secret?
Summary
NPR’s Shortwave explores the secret longevity of Heliconius butterflies, which live 25 times longer than other species by consuming pollen. Science journalist Katie Wu explains that while pollen aids their lifespan, these butterflies possess unique biological adaptations to process it, unlike other insects. The episode also compares this to bats, which extend life through hibernation and controlled immune responses. Ultimately, Wu suggests that while healthy habits help, humans face an evolutionary cap on lifespan that cannot be easily bypassed by simple dietary hacks.
