C. elegans may provide the key to the fountain of youth

Interesting conclusion of research on the roundworm C. elegans by a group at the Massachusetts General Hospital led by Sean P. Curran and Gary Ruvkun suggest that while "people die, one part of them, at least in principle, is immortal."

"The finding may provide an explanation for the many recent experiments in which biologists have made laboratory organisms live longer by manipulating their genes. Most of these genes lie in what is known as the insulin-signaling pathway, which influences the body’s metabolism of fat and glucose.

When the pathway is disturbed, by deactivating one of its genes, the animal generally lives longer. The effect seems similar to the extension of life span enjoyed by laboratory mice when they are kept on a diet very low in calories."
