A GENE discovered by scientists in fruit flies may help experts unlock the secrets of ageing.

The insects have their own equivalent of a key human ageing gene called WRN, researchers have discovered, and experts hope that studying it will help them understand important aspects of the human ageing process.

Flies with damage to the gene share key features with people afflicted by the rapid ageing condition Werner syndrome.

The scientists, led by Dr Lynne Cox from Oxford University, showed that DNA became rearranged, with genes being swapped between chromosomes.
