Lack Of Sleep Among New School-goers Leads To Behavioral, Cognitive Pr
The first investigation of developmental sleep duration patterns throughout childhood shows that children just beginning school and who get little sleep are more likely to have behavioral and cognitive problems in the classroom, according to a new study. The research also suggests that language acquisition and the consolidation of new words into memory could be significantly impeded by chronically shortened sleep duration throughout childhood. Science used to decode the secrets of Olympic skeleton sliding
Olympic skeleton athletes will hit the ice next month in Vancouver, where one-hundredths of a second can dictate the difference between victory and defeat. Using state-of-the-art flow measurements, engineers are employing science and technology to help the US skeleton team trim track times and gain an edge over other sliders. Epilepsy By The Numbers: New Brain Monitoring Method Would Pinpoint Ba
Scientists at the Evelyn F. and William L. McKnight Brain Institute of the University of Florida report they have found a mathematical way to translate complicated brain wave readings into simple terms to help doctors and nurses more easily identify babies at risk for epilepsy. MicroRNA Tweaks Protein That Controls Early Heart Development
Researchers at UT Southwestern Medical Center have discovered how a small molecule of RNA called microRNA - a chemical cousin of DNA - helps fine tune the production of a key protein involved in the early development of heart muscle. Postpartum Health Alliance (PHA)
"PHA is a non-profit, San Diego based organization with the purpose of promoting the emotional and physical well-being of parents and their children after childbirth."The site features a FAQ and a brochure that describes symptoms of abnormal baby blues, and postpartum depression, anxiety, and psychosis. The brochure includes a self-screening test for depression and anxiety. Also includes a bibliography and links to related sites. Galileo To Support Global Search And Rescue
The detection of emergency beacons will be greatly improved by the introduction of Europe's satellite positioning system, Galileo. The Galileo satellites will carry transponders to relay distress signals to search and rescue organizations. Cholesterol Byproduct Blocks Heart Health Benefits Of Estrogen
A byproduct of cholesterol metabolism interferes with the beneficial effects estrogen has on the cardiovascular system, providing a better understanding of the interplay between cholesterol and estrogen in heart disease. The results may explain why hormone replacement therapy fails to protect some postmenopausal women from heart disease. Could epilepsy open a window on the brain?
Guest science writer Michael Marshall tells sciencebase readers about the latest research into epilepsy. The Khmer Rouge Trial Task Force
The website of the Cambodian government task force for the "preparation of the proceedings for the trial of senior Khmer Rouge leaders"features an extensive FAQ on the Khmer Rouge regime, which "took power on 17 April 1975 and was overthrown on 7 January 1979. More than three million people perished."Also provides a chronology (starting in 1997), legislation, and other documents related to the task force and the trial. In Khmer, English, and French. Why Exertion Leads To Exhaustion
Researchers have discovered the dramatic changes that occur in our muscles when we push ourselves during exercise. We all have a sustainable level of exercise intensity, known as the "critical power."This level can increase as we get fitter, but will always involve us working at around 75-80 percent of our maximal capacity. This research shows why, when we go beyond this level, we have to slow down or stop altogether.
