This article from the Scotsman is a little more clear about the implications of the recent RAD51D discoveries. Many news outlets have been reporting this as a major breakthrough in the fight against aging, which isn't the case. It is an important step, and opens up new avenues for cancer and aging research, "but to imply that it might lead to a way of keeping people forever young was completely misleading. Halting the ageing process of cells would run the risk of leaving people ravaged with cancer." Biogerontologist Aubrey de Grey suggests that tackling cancer will be the hardest part of his proposed plan to defeat aging.
