In children’s brain scans, scientists uncovered signs of multiple sclerosis before the kids showed any symptoms of the disease.

Snail not extinct after all; results too good to be true?; mice need myelin production for motor learning; keeping the brain young; the evolution of archaea

The production of new myelin in the brain—a function of non-neuronal glial cells—may be necessary for motor learning, a mouse study shows.

New oligodendrocytes in the adult mouse brain appear to remodel existing myelin sheaths, which may fine-tune the speed of nerve impulses.

In a Phase I trial, researchers show that neural stem cells transplanted into humans can differentiate and begin producing myelin.
