ScienceMag – Naked mole rats defy the biological law of aging
If you are thinking that he has to give up good looks for longevity, then think again. I am sure he is pretty to his mom and to his lady friends. Or else they would not exist and still be making babies.
Scientists have long noted that naked mole rats—burrowing rodents with wrinkled, pink skin and large protruding teeth that live in large, subterranean colonies—show few signs of aging and far surpass the life span expected of a rodent this size. Mice in captivity live at most 4 years; based on their size, naked mole rats would not be expected to live past 6 years. Instead, some live beyond 30 years, and even at that age breeding females stay fertile.
Comparative biologist Rochelle Buffenstein has studied the animals for more than 30 years and has, quite literally, collected a lifetime’s worth of data. For each animal in her care, she recorded the date of birth and when it died, and whether it was killed for an experiment or given away to other researchers.
