Myotonic dystrophy type 1 (DM1) is the most common form of adult-onset muscular dystrophy, affecting about 1 in 8,000 people. While it is well known for causing muscle weakness and stiffness, DM1 also ...

A new 3D model shows that Duchenne gene therapy can repair muscle fibers but fails to shut down the signals that drive scarring.

Using zebrafish larvae, biologists have discovered neural mechanisms that suppress slow muscle activity in fish swimming at high speeds. In vertebrate muscles, there are slow and fast muscle fibers.
