UCLA Study Helps ER Physicians Identify Previously Undetectable Spinal
Patients with a cervical spine injury may harbor additional spinal damage not visible on regular x-rays. Researchers found more than a third of patients who were thought to have low-risk injuries actually have additional damage that may include significant fractures with the potential to produce serious spinal problems if not detected and treated properly. Enlarged Prostate Drug Allows For Less Invasive Prostate Biopsies
A drug that is currently used to treat an enlarged prostate may improve the accuracy of prostate biopsies, a pilot study shows. Serious Adverse Reactions To Smallpox Vaccine Appear To Be Limited
There was a low rate of life-threatening adverse reactions to the smallpox vaccine administered to potential first responders to a bioterrorism incident, possibly attributable to rigorous vaccine safety screening and educational programs, according to a study in the December 7 issue of JAMA. The Online NewsHour: Vote 2006
Background, news, and analysis about the November 2006 elections, with coverage of U.S. House and Senate and state governor races. Features profiles of candidates, reports related to the candidates and races, overviews of key issues (such as Iraq and gay marriage) and lesson plans and other material for students and teachers. From Online NewsHour, a Public Broadcasting Service (PBS) program. Polar Bears Threatened: Million Of Acres To Be Opened To Oil And Gas A
The US government issued its Final Notice of Intent for the Chukchi Lease Sale 193 opening approximately 29.7 million acres of the pristine Chukchi Sea to oil and gas activities on January 2. This controversial announcement comes just days before the U.S. Fish and Wildlife Service is due to decide if the polar bear should be listed under the Endangered Species Act due to severe habitat loss from melting sea ice in Alaska's Arctic Ocean caused by global warming. Pure Spin Currents In Silicon Generated, Modulated, And Electrically D
Scientists have generated, modulated and electrically detected a pure spin current in silicon, the semiconductor used most widely in the electronic device industry. This demonstration is a key enabling step for developing devices which rely on electron spin rather than electron charge, an emergent field known as "semiconductor spintronics."Progress in this field is expected to lead to devices which provide higher performance with lower power consumption and heat dissipation. NYPL Digital Gallery
This site "provides access to over 275,000 images digitized from primary sources and printed rarities in the collections of The New York Public Library [NYPL], including illuminated manuscripts, historical maps, vintage posters, rare prints and photographs, illustrated books, printed ephemera, and more."Searchable, or browsable by collection, such as art and literature, cities and buildings, industry and technology, and nature and science. Clean Air Interstate Rule
In March 2005, the Environmental Protection Agency (EPA) issued "the Clean Air Interstate Rule (CAIR), a rule that will achieve the largest reduction in air pollution in more than a decade."This site features background information and updates about the rule, which mostly affects states in the eastern half the United States through mandates to reduce sulfur dioxide (SO2) and nitrogen oxides (NOx) emissions. Includes the text of the rule and related charts. Smart Insulin Nanostructures Pass Feasibility Test, Study Reports
Biomedical engineers have announced pre-clinical test results demonstrating the feasibility of a smart particle insulin release system that detects spikes in glucose or blood sugar levels and releases insulin to counteract them. Designed to mimic functions of the pancreas which produces the blood-sugar regulating hormone insulin, the smart particle system stabilized blood sugar levels in animal models with suppressed pancreatic functions for up to six hours, researchers reported. It is an inhalable system. Tiny Superconductors Withstand Stronger Magnetic Fields
Ultrathin superconducting wires can withstand stronger magnetic fields than larger wires made from the same material, researchers now report. This finding may be useful for technologies that employ superconducting magnets, such as magnetic resonance imaging.
