A Cross-Species Transcriptomic Aging Clock (opens in new tab)

If one can develop a single aging clock that works in much the same way in both mice and humans, could it be used to determine which of the interventions to treat aging that have been tested in mice are more likely to work well in humans? It is clearly the case that most of the established approaches to slowing the progression of aging, largely derived from manipulation of stress response mechanisms that clean up damage and improve cell function, produce much larger increases in life span in ...
