How Learning Influences Smell The smell of an odor is not merely a result of chemical detection but is also influenced by what the smeller learns about the odor. Now, researchers have discovered how such "perceptual learning"about an odor influences processing of information from the purely olfactory chemical detection system. Evidence Of Gut Parasite Found In Dinosaur University of Colorado at Boulder researchers have discovered what appears to be the first evidence of parasites in the gut contents of a dinosaur, indicating even the giants that roamed Earth 75 million years ago were beset by stomach worms. Breakthrough In Eye Cancer Treatment Scientists at St. Jude Children's Research Hospital have demonstrated in a mouse model a new, locally applied treatment for the eye cancer retinoblastoma that not only greatly reduces the size of the tumor, but does so without causing the side effects common with standard chemotherapy. Engineers Designing Protective Wall To Shield Bridges From Terrorist A Government officials have acknowledged the transportation system's vulnerability to terrorist attacks. Bridges are among the most vulnerable. Because of this reality, researchers at the University of Missouri-Columbia are working with federal highway officials to develop a new technology that can protect bridges against such attacks. Frequency Of Atlantic Hurricanes Doubled Over Last Century, Climate Ch About twice as many Atlantic hurricanes form each year on average than a century ago, according to a new statistical analysis. The study concludes that warmer sea surface temperatures and altered wind patterns associated with global climate change are fueling much of the increase. National Center for Education Statistics: Crime and Safety Surveys (CS Compilation of school crime and safety data and reports, including the annual Indicators of School Crime and Safety (2002 to the present), and surveys of principals, teachers, and students. Includes reports on student discipline, victimization, gangs, bullying, weapons, drugs, and other school violence and crime topics. From the National Center for Education Statistics, U.S. Department of Education. Scientists Map Structure Of DNA-doctoring Protein Complex Mobile DNA, which inserts foreign genes into target cells, is a powerful force in the march of evolution and the spread of disease. Working with the lambda virus and E. coli bacteria, Brown University biologists have solved the structure of a six-protein complex critical to performing this gene-grafting surgery. The technique they developed could be used to reveal the structure of other critical protein complexes, landing the work on the cover of Molecular Cell. Steroid Medications Don't Work In Treating Lower Respiratory Infection The use of steroid medication to treat bronchiolitis -- a common viral lower respiratory infection in infants -- does not prevent hospitalization or improve their respiratory symptoms, according to a recent study. The findings resolve controversy from prior research and are expected to help guide treatment for the most common cause of infant hospitalization. Scientists Use Technology To Tackle Food-Borne Illnesses According to estimates from the U.S. Centers for Disease Control and Prevention, food-borne pathogens account for 76 million illnesses, 325,000 hospitalizations and 5,000 deaths in the United States each year. As the food industry continues to globalize, food safety is expected to remain a significant public health issue. In 2000, UW-Madison made a commitment to help tackle this complex problem by hiring an interdisciplinary group of researchers with expertise in food safety. Suicide In One Partner Substantially Increases Suicide Risk In The Oth Suicide in one partner significantly increases the risk of suicide in the other, finds a large study in the Journal of Epidemiology and Community Health. But there are gender differences, the research shows.
