A ‘fountain of youth gene’ has been identified by scientists.
Experts have long been puzzled as to why young animals recover from injuries more quickly than adults.
The gene, Lin28a, is highly active in unborn children, but does less and less with age.
In tests on mice, it quickened the healing of wounds and sped up regrowth after a patch of fur was shaved.
It also helped repair tissues in the ear after they were injured.
