A pill which could ward off ageing has come a step closer after tests of a rejuvenating drug that prolongs healthy life.
Scientists found that activating a protein called sirtuin 1 (SIRT1) extended the lives of mice and delayed the onset of age-related diseases.
They believe their experiments could lead to drugs that help to keep people younger and healthier.
SIRT1 and its sister protein SIRT2 are known to play a important roles in metabolism across a wide range of species.
