Scientists from Israeli universities did tests to try to stop and reverse ageing. The researchers said the tests were simple - they used oxygen to slow down what happens to cells as they age. The scientists said two processes related to ageing and illnesses slowed down. The scientists did tests on 35 adults over the age of 64 five times a week for three months. The study is published in a magazine called "Ageing".
A professor explained how important the research is. He says the ageing process can be reversed. He says we may be able to stop cells from shortening and that if we can do this, the cells will not age. Researchers are trying to develop drugs to make cells longer so cells do not age. The professor added: "The study gives hope, and opens the door for a lot of young scientists to target ageing as a reversible disease."
