Mayo Clinic researchers have found that multiple exposures to anesthesia at a young age are associated with higher rates of attention-deficit/hyperactivity disorder.

Intermittent exercise with and without low oxygen concentrations can improve insulin sensitivity in type two diabetics, however exercise while under hypoxic conditions provides greater improvements in glycemic control than intermittent exercise alone, according to a recent study accepted for publication in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.

Heart failure is associated with a 30 percent increase in major fractures and also identifies a high-risk population that may benefit from increased screening and treatment for osteoporosis, according to a recent study accepted for publication in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.

The internet is awash with stories of how silver can be used to treat cancer. Now, lab tests have shown that it is as effective as the leading chemotherapy drug - and may have fewer side-effects.

Around the world coral reefs are facing threats brought by climate change and dramatic shifts in sea temperatures. While warming has been the primary focus for scientists and ocean policy managers, cold can also cause significant damage. Scientists at Scripps Institution of Oceanography at UC San Diego have shown that cool temperatures can inflict more damage in the short term, but heat is more destructive in the long run.

The disparity in stroke-related deaths among black and white children dramatically narrowed after prevention strategies changed to include ultrasound screening and chronic blood transfusions for children with sickle cell anemia, according to research presented at the American Stroke Association's International Stroke Conference 2012.

For patients with a type of irregular heart beat called atrial fibrillation, a new anti-clotting drug might be better at preventing clot-related strokes while minimizing the risk of causing a bleeding stroke. The research was presented at the American Stroke Association's International Stroke Conference 2012.

Occasional erratic heart rhythms appear to cause about one-fifth of strokes for which a cause is not readily established, according to research presented at the American Stroke Association's International Stroke Conference 2012.

Being anemic could more than triple your risk of dying within a year after having a stroke, according to research presented at the American Stroke Association's International Stroke Conference 2012.

Scientists working with Professor Bernd Kaina of the Institute of Toxicology at the Medical Center of Johannes Gutenberg University Mainz have demonstrated for the first time that certain cells circulating in human blood - so-called monocytes - are extremely sensitive to reactive oxygen species .

A new protocol, IPv6, is being introduced across the Web. Researchers at Universidad Carlos III of Madrid who are participating in the Trilogy project have defined technology that allows users of this protocol to access Internet contents that are currently only available to users entering the Web using IPv4 protocol.

Scientists at the Max Planck Institute for Chemical Ecology, Germany, are now using a procedure which brings forward ecological research on insects: They study gene functions in moth larvae by manipulating genes using the RNA interference technology (RNAi). RNAi is induced by feeding larvae with plants that have been treated with viral vectors. This method called "plant virus based dsRNA producing system" increases sample throughput compared to the use of genetically transformed plants.

Initial results of a multicenter study coordinated by researchers at Fred Hutchinson Cancer Research Center indicates that two investigational urine-based biomarkers are associated with prostate cancers that are likely to be aggressive and potentially life-threatening among men who take a "watchful waiting," or active-surveillance approach to manage their disease. Ultimately, these markers may lead to the development of a urine test that could complement prostate biopsy for predicting disease aggressiveness and progression.

According to a new analysis of hundreds of recorded office visits, doctors and nurse practitioners typically issued orders and asked closed or leading questions when talking to their HIV-positive patients about adherence to antiretroviral therapy. Attempts at problem-solving with patients who had lapsed occurred in less than a quarter of visits.

An international team of scientists led by Carnegie's Guillem Anglada-Escudé and Paul Butler has discovered a potentially habitable super-Earth orbiting a nearby star. The star is a member of a triple star system and has a different makeup than our Sun, being relatively lacking in metallic elements. This discovery demonstrates that habitable planets could form in a greater variety of environments than previously believed.
