Palo Alto recently showed that transfusing the protein-rich blood of young mice into the parched veins of old mice can reverse the effects of aging in the latter population. Scientists who conducted the experiments reported that older mice saw dramatic improvements to their hearts, muscles, and brains. Because mice share certain proteins with humans, there’s hope that experiments with humans will yield similar results. To learn more about the experiments, check out the links here and here.
