Research on a modified protein around which DNA is wrapped sheds light on how gene regulation is linked to aging and longevity in nematodes, fruit flies and possibly humans. The research has implications for how gene expression is regulated, and could offer a new drug target for age-related diseases.

It's an inevitable side effect of longevity: your hair will turn gray. In this episode, Sophia Cai chats about the chemistry of your natural hair color, why it eventually turns white, and how scientists may be able to slow that graying down.

" The typical naked mole rat lives 25 to 30 years, during which it shows little decline in activity, bone health, reproductive capacity and cognitive ability. What is the secret to this East African rodent's long, healthy life?"

Calorie restriction has long been studied as a way to extend lifespan in animals. It has been associated with the ability to reduce the risks of cardiovascular and other diseases and to improve overall health. Now, researchers at Chang Gung University in Taiwan have found that calorie restriction can ...

Bowhead whales (Balaena mysticetus), denizens of Arctic seas, are known to live more than 200 years, yet they show few signs of the age-related ailments that plague other animals, including humans. Even the bowhead's closest cetacean relative, the much smaller minke whale, lives only 50 years. That suggests the larger whales (which have more than 1000 times as many cells as humans) have evolved some special natural mechanisms that protect them against cancer and aging.
