Scientists reveal how beta-amyloid may cause Alzheimer's

Scientists at the Stanford University School of Medicine have shown how a protein fragment known as beta-amyloid, strongly implicated in Alzheimer's disease, begins destroying synapses before it clumps into plaques that lead ...

Worms may shed light on human ability to handle chronic stress

New research at Rutgers University may help shed light on how and why nervous system changes occur and what causes some people to suffer from life-threatening anxiety disorders while others are better able to cope.

Neuroscience

How neurons get wired

Two different versions of the same signaling protein tell a nerve cell which end is which, UA researchers have discovered. The findings could help improve therapies for spinal injuries and neurodegenerative diseases.
