People Think Bottled Water Is Healthy ... Sort Of
A small study has shown that people tend to believe that bottled water is somehow healthier than water from the tap. However, the research, published in the open access journal BMC Public Health, also shows that people are unsure exactly what these benefits might be and that they are rarely the main reason for choosing bottled.

Meeting To Examine Human Behavior And The Threat Of Disease
As swine flu spread from Mexico to Texas and then fanned out farther in the United States, Americans began to alter their behavior. Families kept children home from school, postponed trips to the mall, and stayed home instead of eating out. In so doing, the American population may have inadvertently altered the behavior of the pathogen itself.

New Study Pinpoints Difference In The Way Children With Autism Learn New Behaviors
Researchers from the Kennedy Krieger Institute and Johns Hopkins University School of Medicine have collaborated to uncover important new insights into the neurological basis of autism. Their new study, published in the journal Nature Neuroscience, examined patterns of movement as children with autism and typically developing children learned to control a novel tool. The findings suggest that children with autism appear to learn new actions differently than do typically developing children. As compared to their typically developing peers, children with autism relied much more on their own internal sense of body position (proprioception), rather than visual information coming from the external world to learn new patterns of movement. Furthermore, researchers found that the greater the reliance on proprioception, the greater the child"s impairment in social skills, motor skills and imitation.

Carbon Monoxide Prevents Clotting

Researchers led by Drs. James F. George and Anupam Agarwal at the University of Alabama at Birmingham have found that carbon monoxide (CO) can protect against arterial clotting. They report their data in the July 2009 issue of the American Journal of Pathology. Carbon monoxide poisoning is extremely toxic; exposure prevents oxygen delivery to body tissues and is often fatal. However, inflamed or injured tissues upregulate heme oxygenase-1 (HO-1), a protein that both protects cells and produces CO, suggesting that low levels of CO may have protective effects. To determine if HO-1 and CO can protect against arterial clotting, Chen et al examined clotting mechanisms in mice that received arterial transplants. Absence of HO-1 in these mice resulted in significant mortality due to arterial clotting; however, treatment with a CO-releasing molecule both decreased clotting and improved survival. Drs. George, Agarwal, and colleagues conclude that HO-1/CO plays an "important role ò€¦[in] protection against vascular arterial thrombosis in murine aortic allotransplantation."
