Researchers pinpoint brain region linked to placebo effect

Researchers have pinpointed a brain region central to the machinery of the placebo effect, the often controversial phenomenon in which a person's belief in the efficacy of a treatment such as a painkilling drug influences its effect.

Cancer risk from radiation during cardiac CT scans studied

An analysis based on computerized simulation models suggests that the lifetime risk of cancer associated with radiation exposure from a computed tomography (CT scan) coronary angiography varies widely, with the risk greater for women and younger patients, according to a study in the July 18 issue of JAMA .
