TORONTO, ON. – For the first time ever, an international team of experts has probed every known death on the world's tallest mountain, shedding some light on what makes Mount Everest one of the most dangerous places on earth.
The team's surprising findings shatter commonly-held beliefs about the prevalence of deaths caused by avalanches, falling ice and pulmonary oedema (lung problems) and highlight severe weather deterioration as a major factor in deaths.
JACKSONVILLE, Fla. – Using a three-dimensional (3D) image-guided system to help place screws in the spines of patients results in safe and accurate surgery with a decrease in the number of misplaced screws, and subsequent injuries, seen in more traditional operations, say neurosurgeons at Mayo Clinic in Florida.
A Princeton University scientist will present new evidence today demonstrating that sugar can be an addictive substance, wielding its power over the brains of lab animals in a manner similar to many drugs of abuse.
Geneva/Hanoi/New York - More than 2000 children die every day as a result of an unintentional, or accidental injury, and every year tens of millions more worldwide are taken to hospitals with injuries that often leave them with lifelong disabilities, according to a new report by the World Health Organization (WHO) and UNICEF.
Measures imposed to reduce exposure to nuts are often based on irrational fears of nut allergies and are becoming increasingly sensationalist, according to a doctor on bmj.com today.
A peanut on the floor of a school bus leading to evacuation and decontamination for fear that it might be eaten by the 10 year old passengers, and schools declaring themselves "nut free" by banning nuts, peanut butter, homebaked goods and any foods without ingredient labels, are just some examples cited in this article.
An international research team led by Massachusetts General Hospital (MGH) investigators has conducted the first detailed analysis of deaths during expeditions to the summit of Mt. Everest. They found that most deaths occur during descents from the summit in the so-called "death zone" above 8,000 meters and also identified factors that appear to be associated with a greater risk of death, particularly symptoms of high-altitude cerebral edema. The report, which will appear the December 20/27 issue of the British Medical Journal has been released online.
The economic cost of death due to cancer is high in the United States, regardless of whether researchers estimate the economic impact in lost work productivity or in a more global measure using the value of one year of life, according to two studies published online December 9 in the Journal of the National Cancer Institute.
CHAMPAIGN, Ill. — Much more cross-gender bullying – specifically, unpopular boys harassing popular girls – occurs in later elementary school grades than previously thought, meaning educators should take reports of harassment from popular girls seriously, according to new research by a University of Illinois professor who studies child development.
Philip C. Rodkin, a professor of child development at the U. of I.'s College of Education, said that while most bullies are boys, their victims, counter to popular conception, are not just other boys.
CHAMPAIGN, Ill. — Traditional classroom teaching in higher education could learn a thing or two from online teaching, otherwise known as e-learning, according to a University of Illinois professor who studies computer-mediated communication, information exchange and the Internet.
Caroline Haythornthwaite, a professor in the Graduate School of Library and Information Science, says that the value of e-learning has been underrated at the college level, and that some of its methods and techniques can augment traditional classroom learning.
(PHILADELPHIA) – A new study from the Abramson Cancer Center and Department of Psychiatry in the University of Pennsylvania School of Medicine shows that smokers who carry a particular version of a gene for an enzyme that regulates dopamine in the brain may suffer from concentration problems and other cognitive deficits when abstaining from nicotine – a problem that puts them at risk for relapse during attempts to quit smoking. The findings, newly published in the journal Molecular Psychiatry, pave the way to identify novel medications to treat nicotine addiction.
(Santa Barbara, Calif.) –– The results of a new U.S.–U.K. study published in this week's journal Nature Nanotechnology show that ordinary people in both countries hold very positive views of nanotechnologies and what the future of these technologies might bring. Participants in both countries indicated a significantly higher comfort level with energy applications of nanotechnologies than with applications used in health treatments.

UCB today announced findings from new studies of the once-daily antiepileptic drug (AED) Keppra XR™ (levetiracetam) extended-release tablets comparing tolerability vs. levetiracetam immediate release and reporting on additional dosing schedules. The data were among five studies that were presented at the 62nd annual meeting of the American Epilepsy Society in Seattle.
Keppra XR was approved by the U.S. Food and Drug Administration in September 2008 for use as adjunctive treatment for people with partial-onset seizures who are 16 years of age and older.
INDIANAPOLIS — Cholinesterase inhibitors, used to treat cognitive symptoms of Alzheimer's disease, are also a safe and effective alternative therapy for the behavioral and psychological symptoms of dementia, according to a study that appears in the December 2008 edition of Clinical Interventions in Aging.
Seattle, December 8, 2008 – Epileptologists are constantly searching for non-invasive or minimally invasive ways to uncover and describe the brain down to its most fundamental cellular and molecular detail and function. Their goal is to achieve the ability to locate and treat the specific cells, neurons or network that start the train of events that produce seizures. Another is to restore cognitive function after possible injury from continuous seizures.
