New CPR guidelines will be released this fall, in an effort to improve how doctors, paramedics and average bystanders do the job.

Cardiopulmonary resuscitation is crucial when people collapse with cardiac arrest, but it's hard to perform correctly.

Authorities ban 1,856 pounds of beef that were shipped to wholesalers in a half-dozen states under rules designed to protect consumers from mad cow disease

New research that allows scientists to fuse adult skin cells with embryonic stem cells has the potential to sidestep much of the controversy surrounding the issue by giving scientists a means to create useful stem cells without first having to create and destroy human embryos.

Harvard scientists say they were able to show in their early research that the fused cell "was reprogrammed to its embryonic state," according to preliminary results published on the Science magazine website.
