Here are 10 animals that have some of the highest levels of testosterone and the impact it has on their behavior and characteristics.

Researchers at the University of Basel have developed a gene therapy that could potentially treat a rare and currently fatal ...

Engineers at Washington University in St. Louis have developed a new class of protein-based fibers modeled on the aligned structure of animal skeletal muscle, producing materials that resist ...

Researchers at UT Southwestern Medical Center have delivered proof of principle in a mouse study demonstrating that embryonic stem cells can be used to spur the development of dystrophin-producing ...

Accomplishing perhaps a world first, researchers at Columbia University and the UChicago-affiliated Marine Biological Laboratory have mapped the full-body muscular activity of an animal while it was ...

Hibernating animals are known to maintain their muscle mass during periods of hibernation, despite the lack of food during these periods. Typically, skeletal muscle undergoes severe atrophy and ...

High-force, high-repetition movements create microinjuries in muscle fibers. Muscle tissue responds by making repairs. But over time, with repetition of injury, healing capacity becomes overwhelmed, ...

Overuse injuries - think muscle strains, tennis elbow, and rotator cuff tears - are a considerable problem in the United States, especially among young athletes. But while commonly associated with ...

One of the downsides to getting older is that skeletal muscle loses its ability to heal after injury. New research from the University of Pittsburgh implicates the so-called "longevity protein" Klotho ...
