Biologists identify pathways that extend lifespan by 500%

by Mount Desert Island Biological Laboratory, Phys.org

Scientists at the MDI Biological Laboratory, in collaboration with scientists from the Buck Institute for Research on Aging in Novato, Calif., and Nanjing University in China, have identified synergistic cellular pathways for longevity that amplify lifespan fivefold in C. elegans, a nematode worm used as a model in aging research.

The increase in lifespan would be the equivalent of a human living for 400 or 500 years, according to one of the scientists.

The Goldilocks Effect in Aging Research

by Salk Institute, Neuroscience News

Ever since researchers connected the shortening of telomeres–the protective structures on the ends of chromosomes–to aging and disease, the race has been on to understand the factors that govern telomere length. Now, scientists at the Salk Institute have found that a balance of elongation and trimming in stem cells results in telomeres that are, as Goldilocks would say, not too short and not too long, but just right.
