Understanding why and how damage to our genes accumulates with age is the first step towards preventing this part of aging. This article from ScienceDaily describes some very clever work that advances our knowledge of the way in which genes are damaged in cells with worn telomeres. A separate article at the LEF News notes an advance in understanding why DNA repair becomes less efficient in older cells. All in all, very interesting stuff. The path to doing something about blocking the genetic mutations that lead to age-related conditions is becoming clearer with each year of funded research.
