A newly developed imaging technique has enabled scientists to map microscopic fiber networks in the brain, muscles, and bones ...

A simple light-based method is uncovering hidden fiber networks inside the brain and body, even in tissue slides over 100 years old.

Building your fast-twitch muscle fibers can help you get stronger and faster. This type of muscle fiber is responsible for the fast, explosive movements used in activities like sprinting, jumping, and ...

When you picture different athletes—marathon runners, gymnasts, and Olympic weightlifters, for example—you likely categorize them instinctively by their height, size, and build. But the differences in ...

Researchers building a model of muscle damage in a cultured system found that components leaking from broken muscle fibers activate ''satellite cells,'' which are muscle stem cells. While attempting ...
