Exercise, typically beneficial for general health, can cause severe “crashes” for those with PEM. Health professionals are struggling to strike a balance between triggering these debilitating crashes and risking muscle mass and strength loss due to lack of exercise.

Neurons Generated from Skin Cells Without Stem Cell Step in Mice
Researchers from the Massachusetts Institute of Technology (MIT) have developed a method to convert skin cells directly into neurons, bypassing the induced pluripotent stem cell
