Philadelphia, Pa. (January 7, 2013) - Athletes with concussions must be held out of practice or play until all symptoms have resolved, to avoid the risk of further injury during the vulnerable period before the brain has recovered.

Los Angeles, CA (January 07, 2013). France has been held up, worldwide, as the forerunner in using nuclear fission to produce electricity. However, a third of the nation's nuclear reactors will need replacing in the next decade, and public opinion has shifted toward reducing reliance on nuclear power. In a special issue of the Bulletin of the Atomic Scientists, published by SAGE four articles explore whether France has the means or desire to unplug from nuclear power.
Gastrointestinal bleeds which occur in the hospital, although rare, are a significant source of morbidity and mortality when they occur. Currently, the prophylactic use of acid-suppressive medication in non-critically ill patients in the hospital is not widely recommended. Despite this, these medications continue to be widely utilized for this purpose.
BOSTON -- Critically ill patients in hospital intensive care units (ICUs) are routinely prescribed acid-suppressive medications to reduce their risk of developing stress ulcers and gastrointestinal bleeding, both of which can result from being in a stressful environment and from being intubated. Over the years, this routine practice has often been extended to patients outside the ICU, despite a lack of evidence that this population is at significant risk of these complications.
When it comes to solving puzzles, animals in captivity are, well, different animals than their wild brethren.
Testing animals' ability to solve new problems has been historically conducted on animals in captivity. Only recently has a shift been made to run these tests on animals in their natural habitat. In a study appearing in Animal Behaviour, however, researchers at Michigan State University found vast differences in the problem solving skills between captive and wild spotted hyenas.
BLOOMINGTON and INDIANAPOLIS, Ind. -- Under the law, whistle-blowers are supposed to be protected from direct reprisals on the job, including discrimination. But what if they and their actions becomes the subject of a widely distributed email? Is that a form of retaliation?
Researchers at Warwick Medical School have discovered that recurrent pregnancy loss can be due to a dysfunctional monthly fertility window. The study, led by Professor Jan Brosens and Professor Siobhan Quenby of the Division of Reproductive Health, sheds new light on the mechanisms that determine the timing and duration of the fertility window and how that may increase the chances of miscarriage.
CAMBRIDGE, MA -- Many industrial plants depend on water vapor condensing on metal plates: In power plants, the resulting water is then returned to a boiler to be vaporized again; in desalination plants, it yields a supply of clean water. The efficiency of such plants depends crucially on how easily droplets of water can form on these metal plates, or condensers, and how easily they fall away, leaving room for more droplets to form.
Smartphones and tablets have become an integral part of our daily lives. The capabilities of these handily sized mini-computers seem almost boundless as we phone friends, shoot holiday snaps, lose ourselves in a new music download or access the internet to obtain the boarding card for our next fl ight in comfort. Does it not seem logical, then, that we should make use of these constant companions as the key to our cars, front doors or lockers as well? A few such solutions are already available, but what's still missing is widespread market acceptance.
Shopping is more than the rational exchange of goods against money. Emotions, however, do not only play a role when buying a red sports car or the fiftieth pair of shoes. At the stock exchange or during auctions, bidders also are often influenced by irrational motives. In the current issue of the International Journal of Electronic Commerce, KIT scientists point out that the end price of auctions depends on the framework conditions and the emotional pressure of the bidders (DOI 10.2753/JEC1086-4415170201).
Philadelphia, Pa. (January 3, 2013) – When initial computed tomography (CT) scans show bleeding within the brain after mild head injury, decisions about repeated CT scans should be based on the patient's neurological condition, according to a report in the January issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.
University of Cincinnati research is revealing how gender and civil status shaped devotional networks in 18th century colonial Latin America, and how economically independent, single women played a key role in shaping the spiritual economy of their communities. Brianna Leavitt-Alcántara, a UC assistant professor of history, will present her research on Sunday, Jan. 6, at the annual meeting of the Conference on Latin American History (CLAH), in New Orleans. The conference is held in conjunction with the 127th annual meeting of the American Historical Association.
DURHAM, N.C. -- You're standing in line somewhere and you decide to open a pack of gum. Do you share a piece with the coworker standing to one side of you, or with the stranger on the other?
Most humans would choose the person they know first, if they shared at all.
But bonobos, those notoriously frisky, ardently social great apes of the Congo, prefer to share with a stranger before sharing with an animal they know. In fact, a bonobo will invite a stranger to share a snack while leaving an acquaintance watching helplessly from behind a barrier.
MAYWOOD, Il. - Millions of Americans read physician ratings on websites such as Healthgrades.com, but such ratings are based on scores from an average of only 2.4 patients, a Loyola University Medical Center study has found.
The study of 500 randomly selected urologists found that 79.6 percent of physicians were rated by at least one of the 10 free physician-review websites researchers examined. Eighty-six percent of physicians had positive ratings, with 36 percent receiving highly positive ratings. Healthgrades had the most physician ratings.
In Ethiopia, where more than 1.2 million people are infected with HIV, disclosure of infection by patients is important in the fight against the disease. A new study led by a Brown sociology researcher investigates HIV-positive status disclosure rates among men and women in Africa's second most populous country.
