Scientists in Israel say they have tests to successfully stop and the biological ageing process. The tests part of a joint project by Tel Aviv University and the Shamir Medical Center. The researchers the science behind their experiments very simple - they only oxygen to slow down and around what happens to cells as they age. They high-pressure oxygen on cells that were in a pressure chamber. The scientists said two processes to ageing and illnesses slowed down. The scientists tests on 35 adults over the age of 64 for 90 minutes a day, five times a week for three months. Their study was published in the magazine "Ageing" on November the 18th.

A lead scientist how important his team's research was. Professor Shai Efrati says the study shows that the ageing process can reversed at the cellular level. He says we may able to telomeres from shortening. Telomeres are inside cells. The shorter they , the more we age. If we can stop them shorter, cells will not age. Professor Efrati said: "Today telomere shortening is the 'Holy Grail' of the biology of ageing. Researchers around the world are to develop [drugs] that enable telomere lengthening." He added: "The study hope, and opens the door for a lot of young scientists to ageing as a reversible disease."
