Genetic engineering creates super mice

Scientific American article on researchers who were able to genetically engineer mice to grow more of a mysterious muscle fiber that lets them run farther and longer than normal mice.

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

Such animals may help to determine the role of this poorly understood type of fiber and to identify drugs capable of counteracting muscle-wasting diseases such as muscular dystrophy in people.
