A new — and reversible — cause of aging: A naturally produced compound rewinds aspects of age-related demise in mice

Researchers have discovered a cause of aging in mammals involving a series of molecular events that disables communication between the nucleus and mitochondria. By administering a molecule naturally produced by the human body, the communication network was restored in older mice. Subsequent tissue samples showed biological hallmarks comparable to much younger animals.
