Summary

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. Reports on pages 104 and 107 show that a signaling pathway that tunes the worm life-span also operates in flies. A third article, published online today by Science (www.sciencexpress.org), reports that a gene related to a member of this pathway likewise influences aging in yeast.
