Scientists Convince a Mouse's Organ to Roll Back Its Own Aging

In a new study, researchers got a specially bred mouse to reverse the course of aging in its thymus. The mouse was engineered so that its thymus would express a specific gene upon exposure to a specific chemical. From there, the induced activity of the gene caused the mouse's thymus to reverse its age-related degradation. The research is far, far away from being useful as a medical intervention. But, this sort of gene-targeted medicine, using the body's own systems to repair itself, is a promising pathway.
