Yes, this study comes with the standard “in mice” caveat. We don’t know if this would replicate in humans. It is interesting though if for no other reason than to illustrate that all calorie sources are not equivalent.
Here is our group’s latest paper in Science. We try to get at genetics of sex differences in lifespan:

In this study we mapped 7 chromosomal regions that modulate lifespan in mice. We are now up to about 35 regions. Of course the goal is to understand the actual processes modulated by each so-called “locus”.
