Scientists Report Cellular Rejuvenation in 80-Year-Old Tissue, Raising New Questions About Whether Aging Can Be Reversed
Researchers have reported a striking laboratory result in which cells taken from an 80-year-old donor were made to behave more like those of a 19-year-old, reviving debate over whether biological aging can be slowed, partially reset, or even reversed. The finding is not a cure for aging, but it adds momentum to a fast-moving field that could reshape medicine, longevity science, and the economics of health in aging societies.
