Germ cell removal may promote longevity

The gonad is well known to be important for reproduction but also affects animal life span. Removal of germ cells - the sperm and egg producing cells - increases longevity of the roundworm Caenorhabditis elegans. However, the underlying molecular mechanisms were a mystery. Now scientists at the Cologne-based Max Planck Institute for Biology of Ageing, have discovered that germ cell removal flips a "molecular switch" that extends the life span by using components of a "developmental clock".
