(From Wired). As if to say that it's dangerous for ethicists to write about fast-moving science, at least one research group has demonstrated that telomeres lengthen rather than shorten in cloned animals. This sort of back and forth on specific findings is characteristic of a young, active field of science - it is something we should be quite happy to see. Apparently contradictory studies usually indicate that scientists are closing in on a previously unknown complexity or mechanism that will explain these results. Since telomeres seem to be an important part of the biochemistry of aging, any and all additional knowledge will help serious anti-aging research.
