As thousands of vacationers hit the beach this summer, many of them will expose their unprotected bare limbs to direct UV sunlight, potentially putting them at risk of skin cancer later in life. To fight back, scientists...

By carefully controlling the position of an atomic-scale diamond defect within a volume smaller than what some viruses would fill, researchers have cleared a path toward better quantum computers and nanoscale sensors. Th...

A chance discovery about the 'wonder material' graphene -- already exciting scientists because of its potential uses in electronics, energy storage and energy generation -- takes it a step closer to being used in medicin...

Among people with type 2 diabetes, eating pistachios may reduce the body's response to the stresses of everyday life, according researchers. "In adults with diabetes, two servings of pistachios per day lowered vascular c...

In an effort to stem substance use, the US has invested heavily in the past decade in a brief screening-and-intervention protocol for alcohol and other drugs. But a new study casts doubt on whether that approach, which h...

Researchers are investigating antibodies to fight Ebola virus, including the three antibodies recently used to treat two American health care workers infected with the Ebola virus. Ebola virus causes an extremely virulen...
