High iron, copper levels block brain-cell DNA repair

No one knows the cause of most cases of Alzheimer's, Parkinson's and other neurodegenerative disorders. But researchers have found that certain factors are consistently associated with these debilitating conditions. One is ...

Schwann cells 'dine in' to clear myelin from injured nerves

Researchers reveal how cells in the peripheral nervous system (PNS) degrade myelin after nerve injury, a process that fails to occur in the central nervous system (CNS). The study appears in The Journal of Cell Biology.

Autism gene stunts neurons, but growth can be restored, in mice

Brown University researchers have traced a genetic deficiency implicated in autism in humans to specific molecular and cellular consequences that cause clear deficits in mice in how well neurons can grow the intricate branches ...

Scientists identify a genetic basis for healthy sleep

From organisms as simple as worms to those as complex as humans, sleep is a fundamental necessity. But although an estimated 50 to 70 million people in the United States suffer from a chronic sleep disorder, the genetic mechanisms ...
