Biologists have found that eliminating germline stem cells, the cells that make eggs and sperm, lengthens the life of fruit flies and alters insulin production. These findings suggest a provocative general principle at work: Molecular signals from the reproductive system affect aging and metabolism in animals -- and possibly in humans. The work also proposes a new mechanism of how this control may occur.

Continually revved up insulin production, the kind that results from overeating and obesity, slowly dulls the body's response to insulin. As a result, blood sugar levels start to creep up, setting the stage for diabetes-associated complications such as blindness, stroke and renal failure. To make matters even worse, chronically elevated blood sugar concentrations exacerbate insulin resistance.
