The Nobel Prize in Physiology or Medicine was awarded this year to three American scientists who solved a problem of cell biology with deep relevance to cancer and aging. The three will receive equal shares of a prize worth around $1.4 million.

Cutting daily calorie intake by 30 percent may put the brakes on the aging process, have beneficial effects on the brain, and result in a longer life span, according to a new 20-year study of monkeys published in the journal Science.

Mutations have been found to extend the lifespan of animals in the lab such as worms, fruit flies and mice, and appear to play the same role in humans. Professor Linda Partridge, director of the Institute of Healthy Ageing at University College London, said such research could help treat or delay many diseases simultaneously with medication.

A study of identical twins reveals the myriad environmental factors make us look older -- or, less frequently, younger -- than our age.
