For the first time, scientists have incorporated multiple human and natural factors into a climate projection model. They predict that increased carbon dioxide in the atmosphere, due to changes in the carbon cycle, combined with a decrease in human-produced sulphates, may cause accelerated global warming during the 21st century, as compared with simulations without these feedback effects. Results of the study, completed by Chris D. Jones and colleagues at the Met Office’s Hadley Centre

Provides more information than conventional x-rays or other scanning methods

Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory, in collaboration with researchers at Rush Medical College, have demonstrated the effectiveness of a novel x-ray imaging technology to visualize soft tissues of the human foot that are not visible with conventional x-rays. The technique, called Diffraction Enhanced Imaging (DEI), provides all of the information imparted by conventio

Ravi Kane Receives Grant From the National Institutes of Health

Ravi Kane, assistant professor of chemical engineering at Rensselaer Polytechnic Institute, is designing brand-new molecules that may one day fend off an HIV infection. Bolstering the body’s molecular defenses is a novel method that may lead to highly effective treatments for HIV, the virus that can lead to AIDS.

Kane has received a two-year, $150,000 grant from the National Institute of Allergy and Infectious Di

After almost 50 years of nuclear materials production at the 586-square-mile Hanford Site in southeastern Washington, there are more than 700 waste sites with the potential to release contaminants to the soil and groundwater. These sites vary significantly in their inventories of radioactive and chemical contaminants and potential for contaminants to migrate through the soil to the groundwater and the Columbia River. Understanding which waste sites have the most significant impact and the cumulative

In the same way dishwashing detergents clean greasy dishes, scientists are using detergent-like surfactants to clean contaminated regions underground.

Cleaning up contaminated soil and groundwater is estimated to cost trillions of dollars in North America. The problem requires many different approaches because there are hundreds of different types of contaminants and the soils and geology differ from place to place. One approach that has shown promise for some situations can be viewed

University of Colorado at Boulder researchers have discovered four new kingdoms of life in the high alpine environment of Colorado, findings that have potential applications in the fields of agriculture and global change.

Doctoral student Allen Meyer and Professor Steven Schmidt of the environmental, population and organismic biology department discovered the new microbe kingdoms in barren, boulder-filled tundra slopes west of Boulder.

At altitudes of 11,000 feet to 13,000 feet in
