Alcohol In Bloodstream Associated With Lower Risk Of Death From Head I
Individuals with ethanol in their bloodstreams appear less likely to die following a moderate to severe head injury, according to a new report. Levels Of Prion Protein In Brain May Not Be Reliable Marker For Diseas
Rapid diagnostic testing used to check for the presence of prion diseases such as "mad cow disease"might fail to identify some highly infectious samples, researchers have found. Rehydrate -- Your RNA Needs It
Water, that molecule-of-all-trades, is famous for its roles in shaping the Earth, sustaining living creatures and serving as a universal solvent. Now, researchers at the University of Michigan and the Academy of Sciences of the Czech Republic have uncovered two previously unknown roles for water in RNA enzymes, molecules which themselves play critical roles in living cells and show promising medical applications. Ladybugs taken hostage by wasps
Are ladybugs being overtaken by wasps? An entomologist is investigating a type of wasp present in Quebec that forces ladybugs to carry their larvae. These wasps lay their eggs on the ladybug's body, a common practice in the insect world, yet they don't kill their host. New Assessment Quantifies Risks And Benefits Of Warfarin Treatment For
Warfarin therapy for patients with atrial fibrillation -- the most common type of significant heart rhythm disorder -- appears to be most beneficial for the oldest patients, those who have had a prior stroke and for patients with multiple risk factors for stroke. Virtual Colonoscopy Shows Cancer Outside The Colon
Computed tomographic colonography (CTC) depicts cancers and other clinically important conditions that would be missed with standard colonoscopy and at very little additional cost. New X-ray Source In Nearby Galaxy Spawns Mystery
Astronomers studying a nearby galaxy have spied a rare type of star system -- one that contains a black hole that suddenly began glowing brightly with X-rays. Though this type of star system is supposed to be rare, it's the second such system discovered in that galaxy, called Centaurus A. The discovery suggests that astronomers have more to learn about the lives and deaths of massive stars in galaxies such as our own. Fossil Patagonian Plants Show High Insect Feeding diversity 52 Millio
South America has the most biodiversity of any major region today and according to an international team of researchers, that biodiversity began at least 52 million years ago. "What defines terrestrial ecology is plant insect interactions,"says Dr. Peter Wilf, assistant professor of geosciences and the John T. Ryan Jr. Faculty Fellow. "But there is very little information about the history of insects eating plants in South America, despite the tremendous number of plant and animal species there today. This study provides the first window to the past on the South American continent's ancient diversity and abundance of insects on plants 52 million years ago." Necklace For Long-term And Robust Cardiac Monitoring In Daily Life
Scientists have developed a prototype of an electrocardiogram or ECG necklace. The technology enables long-term monitoring of cardiac performance and allows patients to remain ambulatory and continue their routine daily activities while under observation. The embedded beat detection algorithm copes with the artefacts inherent to ambulatory monitoring systems. Controlling x-rays with light: Step toward controlling how matter beha
Controlling x-rays with ultrashort slices of light is a step toward controlling how matter behaves, shaping x-rays with other x-rays, and eventually directing the paths chemical reactions can take. Working with the femtosecond beamline at Lawrence Berkeley National Laboratory's Advanced Light Source, a team of scientists shows how it can be done.
