It'll be interesting to see if Google can expand the service fast enough to keep up this momentum. I like chatting it up in 140 characters or more and Google+ is just so light, fresh and fun. It's like Happy Hour all day long.
The discovery of this gene could explain why some people are better endurance runners than others, and if discovered in humans (or any other animal, for that matter), could be used to create a human that could run and run and run and run. Although, the absence of speed and power might not be worth it.But these behavioral quirks weren't quite enough to convince Khurana of the effect on muscles. Lack of the IL-15Rα gene could just be making the mice jittery or giving them extra energy. So the researchers dissected muscles from the longer-running mice. The muscles sported increased numbers of energy-generating mitochondria and more muscle fibers, indicating that they tired less easily. And when the researchers stimulated them with electricity, the muscles continued to contract for longer than normal, taking longer to use up their energy stores, the team reports in The Journal of Clinical Investigation.
