A gene from 100-year-olds could help kids who age too fast

Scientists have discovered that a “longevity gene” found in people who live beyond 100 can reverse heart aging in models of Progeria, a devastating disease that causes children to age rapidly. By introducing this supercentenarian gene into Progeria-affected cells and mice, researchers restored heart function, reduced tissue damage, and slowed aging symptoms. The discovery opens the door to new therapies inspired by the natural biology of long-lived humans—possibly reshaping how we treat both rare diseases and normal aging.
