The New Take on Aging: Your Body Is Actively Working Against You

This article in Scientific American reports on a study published in Cell that found certain genes in C. elegans that appear to switch on the aging process. (You can see where this is going, can't you?) The story quotes Marc Tatar, a biologist not involved in the research, as saying, "The take-home message is that aging can be slowed and managed by manipulating signaling circuits within cells." Stuart Kim from Stanford was senior author on the paper.
