Wine molecule slows aging process
Called resveratrol, a wonder substance discovered by Harvard researchers seems to work in the same way as does drastic calorie cutting. Dramatic reduction of calories has been shown to increase the life span of mice, rats, and monkeys. Such diets are being tried in humans but results are not yet in. Severe dieting also cuts…

Eating less and living longer
Tantalizing evidence exists that cutting calories by 20 percent helps monkeys, who are close relatives, to live longer, healthier lives. And, in one nonscientific program, adults are reducing their caloric intake by as much as 30 percent in the hope of living healthfully (if not too happily) for 100 years or more. What if scientists…

New molecular model increases longevity and could allow you to eat cake, too
Scientists have known about the longevity benefits of caloric restriction since experiments in the 1930s showed that rats lived much longer if their food intake was severely restricted. Broadly speaking, the reason is stress. Although usually viewed as the enemy of good health, stress can actually boost longevity, driving an organism to slow down metabolism…

Cancer cells’ immortality may depend on longevity protein
A team of Harvard Medical School researchers has identified a protein that 10 percent of tumor cells use to attain an immortal state. By blocking the molecule, it may be possible to stop these cancer cells from proliferating. The approach might also be used as part of a two-pronged strategy to combat the remaining 90…
