A national conference on obesity will explore questions such as: are schools responsible for helping students maintain a healthy weight?

Women's natural estrogen levels help protect against cognitive decline, UCSF/VA study says
Older women with high estrogen levels are less likely to suffer cognitive decline, says a new study from researchers at the University of California, San Francisco and the San Francisco Veterans Affairs Medical Center.

Coronary calcium scan may be important tool in identifying Type 1 diabetics who are at high risk for heart disease
A new report which will appear in next month's issue of the journal Diabetes indicates that a heart scan using electron beam computed tomography (EBCT) may be an important tool in identifying Type 1 diabetics who are at particularly high risk of developing heart disease.

Scientists create organic photovoltaic devices to convert light into electricity
Virginia Tech researchers from physics, chemistry, and chemical engineering are working with a local company to create thin films that convert light into electricity.

'Strikingly Similar' protein may be in Alzheimer's and Mad Cow Disease
A 'striking similarity' between proteins involved in the early stages of Alzheimer's disease and mad cow disease was described here today at the 220th national meeting of the American Chemical Society.

Improvement in controlling agricultural runoff still needed to prevent ecological disasters
Growing tomatoes using plastic mulch, raised beds, and drip irrigation controls soil moisture and prevents weeds, which reduces the need for herbicides and fertilizers, thus reducing contamination by these chemicals.

OHSU researchers capture cell transmissions on tape for first time
Researchers at Oregon Health Sciences University's Vollum Institute report they have successfully captured on videotape the transmission of vesicles at a synapse.

Scientists combine chemistry and bioremediation to clean cadmium from soil
Scientists at the US Department of Energy's Brookhaven National Laboratory have devised a way to combine chemical treatment with 'pollutant-busting' bacteria to remove cadmium from contaminated soil.

Brief exposure to nicotine makes lasting mark on the brain
By usurping a mechanism responsible for learning and memory, low levels of nicotine can quickly cause lasting changes in the brain's reward areas.

Major air pollution study launched
A national team of over 150 researchers has begun one of the most comprehensive air quality studies ever conducted in the US.

Chemists report new approach to synthetic fragments of medically important Heparin
Chemists at the University of Georgia have developed a new method of synthesizing the principal constituent units of Heparin, a widely used anti-coagulant that is thought to be involved in numerous biological processes with proteins.

Brown engineering and neuroscience group wins grant for brain study
Six Brown scientists plan to explore the function of the human brain using tiny electronics -- nanotechnology -- with a $4.25 million grant from the US Defense Department.
