Life span: getting the signal from the nervous system.

Abstract excerpt

Life span is determined by both environmental and genetic influences. The importance of genes is illustrated by the fact that single gene mutations extend life span in nematodes, fruit flies and mice. Recent reports reveal that the life span of Caenorhabditis elegans is controlled by insulin-like signals from the nervous system. Hormones that control life span have recently been identified in fruit flies and...
