Bats are the longest-living mammals relative to body size, and a species called the greater mouse-eared bat lives especially long. Researchers now have unlocked some of this bat's longevity secrets, with hints for fighting the effects of aging in people.
Scientists said on Wednesday that unlike in people and most other animals, in this bat species the structures called telomeres located at the end of chromosomes, thread-like strands inside a cell's nucleus that carry genes determining heredity, do not shorten with age.
Only 19 mammal species are longer-lived than humans relative to body size. Eighteen of them are bats, some living more than four decades. The other is a weird African rodent called a naked mole rat.
