Ovaries Play a Role in Mammalian Aging
From the LEF News, a fairly brute-force study concludes that we should be looking into the functions of the ovaries in mammals for more clues to biochemical controls involved in the aging process. Scientists have already determined that a small number of genetic changes (which lead to differences in biochemical processes in the body) extend life in nemotode worms, flies and mice. This research is complementary, indicating other avenues of investigation. It's certainly a sign of the times that it seems crude to be performing experimental transplants rather than genetic therapy or biochemical assays.
