dmm"Gene Therapy-Mediated Partial Reprogramming Extends Lifespan and Reverses Age-Related Changes in Aged Mice"
A Feb 24 paper seems to claim an impressive result in "wild-type" mice via a partial cellular reprogramming protocol, which includes cyclic administration of doxycycline for temporal control of reprogramming, and which does not seem to be particularly cancer-inducing (that's usually a big problem with cellular reprogramming).. 124-week male mice, Doxycycline-treated controls average survival till 133 weeks, treatment group average survival till 142.5 weeks (for a human something like this would roughly double remaining life expectancy of a 75-year old male from about 10 more years to about 20 more years if equally efficient).
It would be nice if this turns out to be a real breakthrough (we have learned from experience to be very skeptical about claims in this field of study).

(One should always be skeptical about all this, but this one is also promising.)
