Life-extending mutation preserves fly hearts

Abstract: Slowing the aging clock keeps the heart ticking strong, according to new work in flies. Insects with a life-stretching genetic alteration maintain robust heart rates and withstand cardiac stress better than do normal insects. The work shows that a mechanism that stalls aging in the entire organism also hinders deterioration of particular tissues.
