š¢ What can a 194-year-old tortoise teach us about aging?
Researchers studying Jonathan, the worldās oldest known terrestrial animal, have identified genetic variations and DNA methylation patterns that may help scientists investigate how some animals live exceptionally long lives.
The findings highlight potential roles for mitochondrial processes, DNA repair, and gene regulationābut researchers caution that the study does not prove what caused Jonathanās extraordinary age or offer a treatment for human aging.
