Fruit flies’ mitochondria (green) when the animals were 10 days (top left), 28 days (top right) and 37 days old (both bottom images). At bottom right, the fly’s mitochondria returned to a more youthful state after UCLA biologists increased the fly’s level of a protein called Drp1.
Anil Rana, David Walker and UCLA colleagues showed that a seven-day, midlife intervention substantially prolongs both the health and the lifespan of the fruit flies.
