Research opens up new directions for studying prion diseases in humans

The mysterious, highly infectious prions, which cause the severe destruction of the brain that characterizes "mad cow disease" and several human brain degenerative disorders, can be rendered harmless in the laboratory by a slight alternation of the three-dimensional conformation or shape of the prion protein's structure.

Excessive sleepiness in adolescents may indicate more than just lack of sleep

A new technical report from the American Academy of Pediatrics (AAP) and the National Center on Sleep Disorders Research (National Heart, Lung, and Blood Institute, NIH) says that although sleepiness is rather common in this age group, pediatricians should pay special attention to patients who exhibit evidence of excessive sleepiness because it could indicate an underlying medical or mental health condition.
