Abstract: New work offers tantalizing clues about possible connections between life-span, DNA damage, and the health of chromosome ends. Although the newly discovered sequence of a longevity gene suggests that it controls the length of telomeres--chromosome caps that shrink each time a cell copies its DNA--the three teams that are independently studying it disagree about that potential function. Additional clues suggest that the gene has DNA-mending capabilities, which could be the key to its life-extending powers.
