Posted: 16 Nov 2015 09:06 AM PST

By studying mice without microbiota, scientists were able to demonstrate how the absence of microbiota has a remarkable effect against obesity.

Duchenne muscular dystrophy is a stem cell disease

Posted: 16 Nov 2015 09:06 AM PST

For nearly 20 years, scientists have thought that the muscle weakness observed in patients with Duchenne muscular dystrophy is primarily due to problems in their muscle fibers, but new research shows that it is also due to intrinsic defects in muscle stem cells. Muscle stem cells that lack the dystrophin gene can't sense their orientation and produce ten-fold fewer muscle precursor cells, which in-turn generate fewer functional muscle fibers.
