Mystery muscle boost leads to super-mice
From USAToday.com

Throwing a genetic switch helps mice grow more of a mysterious muscle fiber that lets them run farther and longer than normal mice, a paper in the January issue of the journal Cell Metabolism reports.

A team at Harvard Medical School was able to increase the activity of a gene called PGC-1 beta in the mice.

The gene increases the growth of a little-understood muscle fiber called IIX, which is very efficient and very quick.

Usually a muscle fiber is one or the other.

The more IIX fibers in a muscle, the longer and harder it can work.

This could lead to drugs that change the composition of muscle, boosting strength and endurance in patients with muscle-wasting conditions, such as paraplegia and muscular dystrophies, says Bruce Spiegelman, who led the research.

that last paragraph seems to be tacked on to the end of any research done in this field lately, almost to the point that it's losing any credibility as a "lifesaver" for those diseases or as a viable alternative or supplement for bodybuilding (even though they don't claim that as a result, but you know there are guys thinking about it). I haven't heard any real news about any of them panning out to be efficient ways of helping out these conditions. has anyone else? they just keep saying it could be a possibility in the future.

Yeah, science is for douchebags. You tell 'em, benchdude.

you obviously have no clue about the point I was making.
