Youth-drug can ‘reverse’ ageing in animal studies

December 20, 2013

US scientists have performed a dramatic reversal of the ageing process in animal studies. They used a chemical to rejuvenate muscle in mice and said it was the equivalent of transforming a 60-year-old’s muscle to that of a 20-year-old – but muscle strength did not improve. Their study, in the journal Cell, identified an entirely new mechanism of ageing and then reversed it. (BBC)
