Parental age effect on the longevity and healthspan of flies and worms

A new study found that the progeny of successive generations of old parents had significantly shorter lifespans than those from young parents in both Drosophila melanogaster and Caenorhabditis elegans. The researchers also discovered that switching to only one generation of younger parents improved the healthspan of the offspring.
