From EurekAlert, news of more good research work on the genetic underpinnings of the aging process. This whole process is much like unraveling a ball of tangled yarn. Scientists know some of the basic mutations that extend lifespan, and now they are much closer to understanding how these mutations actually work. This latest set of results was for the humble roundworm, but is still very applicable to further research in humans. It is very exciting to see our understanding of the mechanisms of aging advancing in such leaps and bounds in a few short years!
