Aging reversed through mitochondrial DNA replenishment

Researchers have reversed wrinkled skin and hair loss, hallmarks of aging, in a mouse model. When a mutation leading to mitochondrial dysfunction is induced, the mouse develops wrinkled skin and extensive, visible hair loss in a matter of weeks. When the mitochondrial function is restored by turning off the gene responsible for mitochondrial dysfunction, the mouse returns to smooth skin and thick fur, indistinguishable from a healthy mouse of the same age.

Maple trees are best known for their maple syrup and lovely fall foliage. But it turns out that the beauty of those leaves could be skin-deep — and that’s a good thing. Today, scientists report that an extract from the leaves may prevent wrinkles.
