Solving the mystery of ageing

Why do we get older? When do we die and why? Is there a life without ageing? For centuries, science has been fascinated by these questions. Now researchers from Kiel (Germany) have examined why the polyp Hydra is immortal – and unexpectedly discovered a link to ageing in humans. The study carried out by Kiel University together with the University Medical Center Schleswig-Holstein (UKSH) will be published this week in the Proceedings of the National Academy of Sciences of the United States of America (PNAS). It was funded by the German Research Foundation DFG.
