The microRNA lin-4, which was previously found to play a role in developmental timing in C. elegans, also regulates lifespan in the worm, according to research from the lab of Yale University's Frank Slack.

The findings, published in the Dec. 23 issue of Science, suggest the existence of a "developmental clock" controlling aging, and may ultimately lead to human therapies for various age-associated disorders.
