Advances in age-old questions.

Drosophila melanogaster is an ideal model organism for various types of aging studies. They are easy to maintain, relatively inexpensive, have short life cycles, provide large sample sizes, and can be genetically manipulated via various methods for testing. The 49(th) Annual Drosophila Research Conference, held in San Diego, CA (April 2-6, 2008), had over 30 poster presentations and eight platform talks devoted to physiology and aging, and seven presentations in a longevity and functional senescence workshop. The data presented via these avenues included life span manipulation, physiological related genes, candidate aging genes, gene expression, signaling, and using D. melanogaster as a model for age related disease, to name a few. This report provides highlights of some of the information presented in the poster, platform and workshop presentations.
