From the Science Friday web site:
In work published this week in the journal Nature, researchers discuss how one gene found in yeast seems to play a role in regulating the organism's lifespan. The gene, named PNC1, appears to turn on in periods of calorie restriction, a condition that has been found to extend lifetimes in some organisms. The researchers said that a yeast strain whose genome contains five copies of PNC1 lives 70 percent longer than a 'normal' strain. We'll talk about what the find might mean, as well as other genetic clues to the aging process.
