But I was mistaken: A recent Taiwanese study demonstrated that taking multivitamins does indeed make people feel protected against [...]

Yes, Red Wine May Hold Some Answers. Recheck Dosage.

Sirtuin News For Mammals
The negative buzz about sirtuins recently grew louder when Science ran a lengthy news piece on Dec. 2 titled, “Aging Genes: The Sirtuin Story Unravels.” The article played up studies in lower organisms casting doubt on earlier high-profile reports that sirtuin enzmes play major roles in aging, which in turn challenged the idea that they [...]

One for the Record Book
Here’s a curious coincidence: The current world records for human longevity and for running the mile were both set back in the 20th century. The longest-lived human was France’s Jeanne Calment, who reached 122 years and 164 days of age before her death in 1997. In 1999, Morocco’s Hicham El Guerrouj ran the world’s fastest [...]

Yet another twist on sirtuins—with leaping ant queens
It’s not often that 33 scientists jointly pen a public complaint that an article in Science got things wrong. But in this week’s issue of Science nearly three dozen researchers working on sirtuins, the enzymes thought by many scientists to help induce the health- and longevity-promoting effects of calorie restriction (CR), complain in a letter [...]
