I’m not so sure that this is an “anti-aging breakthrough”, as I don’t think too many people die from cell replicative senecence (i.e. the Hayflick limit isn’t a key reason we die when we do), but probably helpful in some area. And, this study is in yeast.
The paper, if someone has access make a PDF and post.
Reprogramming cellular dynamics is used to study and delay the onset of aging in yeast
