A clinical trial found a reduction in seizures and improvement in related symptoms, including depression and anxiety, in patients with psychogenic nonepileptic seizures who were treated with cognitive behavioral therapy ...

Full implementation of the Affordable Care Act's national health insurance expansion could result in many more discretionary surgical procedures in the next few years based on how utilization changed after an earlier ins...

Women with long-term high blood pressure appear to be at an increased risk for the skin condition psoriasis, and long-term use of beta (²)-blocker medication to treat hypertension may also increase the risk of psoriasis...

Polyphenols -- compounds found in cocoa and other foods -- may help people with peripheral artery disease walk a little longer and farther before pain sets in. More research is needed to see whether long-term use of thes...

A runaway trolley is out of control. Ahead of it on the tracks are five people tied up and unable to move. You are too far away to untie the people, but if you act quickly, you could push a very large man in front of the...

Researchers have found that the risk of patient harm increased two-fold in 2006 -- the peak year that teaching hospitals nationwide embraced the pursuit of minimally invasive robotic surgery for prostate cancer.

People with mild to moderate Parkinson's disease who regularly walk for exercise may improve their motor function, mood, tiredness, fitness and some aspects of thinking abilities, according to a study. The study included...

Lung cancer patients could receive more precise treatment, and their progress could be better tracked, using a new high-tech method of non-invasive medical imaging analysis, according to a study. Genetic changes increasi...

Significant gaps in hepatitis C care identified in a new meta-analysis will prove useful as the U.S. health care system continues to see an influx of patients with the disease because of improved screening efforts and ne...

A novel intravaginal ring implanted with anti-retroviral drug tablets, or pods, demonstrated sustained and controlled drug release and safety over 28 days, according to a study. The ring, designed to prevent transmission...

Using computer-automated, time-lapse photography of embryos in the laboratory during in-vitro fertilization may improve embryo selection, potentially increasing the chances of pregnancy among women undergoing the procedu...

Researchers have identified a way to enhance regrowth of human corneal tissue to restore vision, using a molecule known as ABCB5 that acts as a marker for hard-to-find limbal stem cells. The research is also one of the f...

The first national model to investigate the bovine TB spread has been developed by researchers in England. The results derived from the model demonstrated that the majority of herd outbreaks are caused by multiple transm...

Neuroscientists leading the largest longitudinal adolescent brain imaging study to date have learned that a number of factors -- genetics, brain function and about 40 different variables -- can help scientists predict wh...

Researchers have shown for the first time that stem cells created using different methods produce differing cells. The findings provide new insights into the basic biology of stem cells and could ultimately lead to impro...

Adipose-derived stem cells, which can generate bone tissue, appear resistant to the toxicity of the chemotherapy drug methotrexate, which degrades bone in patients such as kids suffering from acute lymphoblastic leukemia...

Physicists at Queen Mary University of London have set up a new pitch drop experiment for students to explore the difference between solid and liquids.

Research to curb global warming caused by rising levels of atmospheric greenhouse gases, such as carbon dioxide, usually involves three areas: Developing alternative energy sources, capturing and storing greenhouse gases...

Researchers have developed a new design for the framework of columns and beams that support bridges, called "bents," to improve performance for better resistance to earthquakes, less damage and faster on-site constructio...

July 2012 is no longer the hottest month ever recorded in the United States. Here's why.

The parents of children with autism, who don't have the condition themselves, may have some of the traits of people with autism, a new study shows.

Researchers at the Cockrell School of Engineering at The University of Texas at Austin have created a new nonlinear metasurface, or meta mirror, that could one day enable the miniaturization of laser systems.
