Abstract

Beneficial effects of social interaction on aging have been studied in humans and other species. We found that short-lived Drosophila mutants of the antioxidant enzyme Cu/Zn superoxide dismutase displayed a robust lifespan extension, with improved stress resistance and motor ability, upon cohousing with active flies of longer lifespan or younger age. Genetic, surgical, and environmental manipulations revealed motor and sensory components in behavioral interactions required for the lifespan extension induced by cohousing. Our results provide a definitive case of beneficial social interaction on lifespan and a useful entry point for analyzing the underlying molecular networks and physiological mechanisms.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
