Researchers explore wood smoke's threat to Great Lakes environment
The Great Lakes region has long been valued for its recreational opportunities, but there may be a price to be paid: A new study has found that wood smoke, most likely from campfires and residential fireplaces, is toxic to certain aquatic organisms in the lakes and is a source of air pollution in the region.

Radio waves stop marine pests dead in their tracks
A new method for killing zebra mussels, which cause millions of dollars in damage to boats and power plants, will be described during the national meeting of the American Chemical Society, the world's largest scientific society, in Chicago, August 26-30.

URI scientist receives research award from National Park Service

Measuring brain activity in people eating chocolate offers new clues about how the body becomes addicted
Using PET scans to measure brain activity in people eating chocolate, a team of U.S. and Canadian neuroscientists believe they have identified areas of the brain that may underlie addiction and eating disorders.

Whale of a Puget Sound problem lures UW researchers
As the fedeal government inches toward listing Puget Sound's orca whales for protection under the Endangered Species Act, University of Washington researchers have launched a multiyear effort to determine the cause of the marine mammals' plummeting population.

Implanted defibrillators: How well do they work?
Doctors say that while it had been believed that most patients who die of heart disease suffer from a progressive failure of the organ, more often patients die from an abrupt malfunction of the heart rhythm -- a condition that can be treated by an implantable defibrillator.

From silkworm silk, hybrid materials that surpass original
Researchers at Cornell University say they are well advanced in creating a polymer of silkworm silk that both mimics and improves on nature, they reported at the national meeting of the American Chemical Society at McCormick Place, Chicago.

Plastic tube may help treat paralysis
Canadian researchers have created a plastic tube that fits around the spinal cord and restores some movement in paralyzed rats.

'Imprinted' gels hold promise for future medical devices
Scientists at Purdue University are creating a biological sensor for glucose in research that ultimately may help to design

Counting single electrons in a carbon nanotube
By probing single-wall carbon nanotubes with an atomic force microscope, researchers at Cornell University have found new ways to cut and bend the tiny tubes, and have learned how to feel the force of a single electron as it hops on and off the tube, they reported at the annual meeting of the American Chemical Society.

Too much soy could lead to kidney stones
New research indicates that soybeans and soy-based foods, a staple in the diets of many health-conscious consumers, may promote kidney stones in those prone to the painful condition.

New chemistry being developed for delivery of neuroprotective drugs
One approach to treating neurodegenerative disease such as Parkinson's disease is to interfere with the chemistry involved.

Enzyme mimetic compound could reduce complications of diabetes
Severe, long-term complications of diabetes, a growing health problem that affects an estimated 16 million Americans, may be reduced with new treatments based on an 'enzyme mimetic' that has been shown to significantly improve the functioning of blood vessels and nerves in diabetic animal studies, as reported in the September issue of the British Journal of Pharmacology.
