Prion infection of neurons increases the free cholesterol content in cell membranes

A new study published in the online open access journal BMC Biology suggests that disturbances in membrane cholesterol may be the mechanism by which prions cause neurodegeneration and could point to a role for cholesterol in other neurodegenerative diseases.

Staging mock cardiac and respiratory arrests expose weaknesses in hospital emergency response for children

Staging mock cardiac and respiratory arrests - "code" situations in hospital parlance - easily expose common failures in rapid response with CPR and other life-saving care for children and also set up powerful incentives to sharpen emergency skills and move fast to use them, suggests a study from the Johns Hopkins Children's Center.
