Socializing with Youth Improves the Elderly's Health, Life Span
Mercredi 06 Août 2008 - 22:00 - 5 mois depuis - Presse spécialisée - Scientific American “Youth is a wonderful thing,” George Bernard Shaw once said. “What a crime to waste it on children.” Humor aside, recent research suggests that youthful energy may not be “wasted” after all. Through social interactions alone, the young can pass some of their vigor on to the elderly, improving the older generation’s cognitive abilities and vascular health and even increasing their life span.Although researchers have documented these benefits in mammals, such as rats, guinea pigs and nonhuman primates, the reason for the effect has remained unclear. Now biologist Chun-Fang Wu of the University of Iowa offers a genetic explanation in the May 27 issue of the Proceedings of the National Academy of Sciences. Wu and graduate student Hongyu Ruan found that the presence of youthful, active fruit flies doubled the life span of a group of flies with a mutation in Sod1, a gene that has been linked in humans to Alzheimer’s disease and amyotrophic lateral sclerosis (ALS), a motor-neuron disorder also known as Lou Gehrig’s disease.
