Higher levels of stress, hostility and depressive symptoms are associated with significantly increased risk of stroke or transient ischemic attack (TIA) in middle-age and older adults, according to new research. A TIA is...

New light has been shed on the complex processes of nerve cell growth, showing that a particular protein plays a far more sophisticated role in neuron development than previously thought. Specifically, the research sheds...

The child known as the 'Mississippi baby' -- an infant seemingly cured of HIV that was reported as a case study of a prolonged remission of HIV infection in the New England Journal of Medicine last fall -- now has detect...

Nuclear engineers have developed a small, portable and inexpensive radiation detection device that should help people all over the world better understand the radiation around them, its type and intensity, and whether or...
