Contemplating the Olm

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

From LiveScience: "Blind salamanders once thought to be baby dragons can live at least as long as most people, scientists now find. Adults of this species live nearly 69 years on average, with a predicted maximum age of more than 100 years, three times longer than related species Surprisingly, the long-lived amphibian doesn't seem to have an especially low metabolism nor unusual levels of protective antioxidant molecules to explain why it lives so long. As such, this salamander could help uncover mechanisms that could help keep us young. The olm or proteus (Proteus anguinus) lives in the limestone caves of southern Europe. ... Zoologists have been intrigued by the olm for centuries because of its longevity, as it often lives more than 70 years in zoos. The salamander's longevity is especially unusual given its tiny size. ... So why might the olm have such an outstanding life span? It might live a long time by not living very much at all. ... Although the olm does not have a remarkably low metabolic rate, it is extremely inactive during its life." Examining animals that are long-lived in comparison to similar species may give more of an insight in the biology of aging. Studies of naked mole-rats are proving fruitful, for example.
