The secret to a long life? A protein that acts as a cellular ‘time machine’ is found to extend the lifespan of fruit flies by 20%

Biologists have turned back the clock on ageing in the cells of fruit flies, by increasing levels of a protein called Drp1.

This cellular time machine was found to lengthen the life-span of the insects by between 10 and 20 per cent.

Experts hope to develop drugs to mimic this effect in humans with age-related diseases including Alzheimer’s, extending¬†people’s life expectancy and giving them more healthy years towards the end of their lives.
