Abstract: Science 292, 41-43 (2001).

Simple evolutionary arguments don't demand that organisms share mechanisms of aging, but new work is strengthening the case that common processes control the life-spans of biology's favorite model systems. Two reports in the 6 April 2001 issue of Science (pp. 104 and 107) show that a signaling pathway that tunes the worm life-span also operates in flies. A third article published in the 13 April issue of Science (p. 288) reports that a gene related to a member of this pathway likewise influences aging in yeast.
