New Approach Assesses Risk Of Water-borne Pathogen Disease UCSD School of Medicine, along with the University Peruana Cayetano Heredia in Lima, Peru, have developed a novel approach for assessing the risk to humans of acquiring leptospirosis -- a severe, water-borne disease that is the common cause of severe jaundice, renal failure and lung hemorrhage in urban areas throughout the developing world -- from environmental water exposure. Geologist Analyzes Earliest Shell-covered Fossil Animals The fossil remains of some of the first animals with shells, ocean-dwelling creatures that measure a few centimeters in length and date to about 520 million years ago, provide a window on evolution at this time, according to scientists. Their research indicates that these animals were larger than previously thought. Now in Broadband: Acoustic Imaging of the Ocean Researchers have developed two advanced broadband acoustic systems that they believe could represent the acoustic equivalent of the leap from black-and-white television to high-definition color TV. For oceanographers, this could mean a major upgrade in their ability to count and classify fish and to pinpoint tiny zooplankton amid seas of turbulence. Alzheimer's Disease: Amyloid Precursor Protein -- Good, Bad Or Both? New data about amyloid precursor protein, or APP, a protein implicated in development of Alzheimer's disease, suggests it also may have a positive role -- directly affecting learning and memory during brain development. So is APP good or bad? Researchers say both, and that a balance of APP is critical. Smooth Deployment For Second MARSIS Antenna Boom The second 20-metre antenna boom of the MARSIS instrument on board Mars Express was successfully -- and smoothly -- deployed, confirmed today by the ground team at ESA's European Space Operations Centre. 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. Blogger Jailed for Slamming Islam Outspoken criticism of Muslim extremists and Egypt's president earns an Egyptian man a four-year prison sentence. By the Associated Press. New key factor identified in the development of Alzheimer's disease A small protein found in the gene- ß -amyloid precursor protein, APP, has been identified as a novel factor for the development of Alzheimer's disease related endosome abnormalities, which have also been tied previously to the loss of brain cells in Alzheimer's disease. Eating Walnuts With High-fat Meals Helps To Protect Arteries Against S New research shows that consuming a handful of raw walnuts along with meals high in saturated fat appears to limit the ability of the harmful fat to damage arteries. Adding olive oil, however, does not provide the same type of vascular protection. The research, conducted at the University of Barcelona's Hospital Clínico, appears in the Oct. 17, 2006, edition of the Journal of the American College of Cardiology. 'Bloodbot' Helps Keep Canadian Blood Clean A unique robotic device is helping University of Alberta researchers confirm that hemophiliacs in Canada are receiving clean, safe blood.
