Roasting coffee beans a dark brown produces valued antioxidants: UBC food...

Food scientists at the University of British Columbia have been able to pinpoint more of the complex chemistry behind coffee's much touted antioxidant benefits, tracing valuable compounds to the roasting process. Lead author Yazheng Liu and co-aut...

Chemists document workings of key staph enzyme — and how to...

CHAMPAIGN, Ill. -- Researchers have determined the structure and mechanism of an enzyme that performs the crucial first step in the formation of cholesterol and a key virulence factor in staph bacteria. Chemists at the University of Illino...

Look: What your reaction to someone’s eye movements says about your...

It goes without saying that conservatives and liberals don't see the world in the same way. Now, research from the University of Nebraska-Lincoln suggests that is exactly, and quite literally, the case. In a new study, UNL researchers measured bot...

University of Toronto physicists create supernova in a jar

A team of physicists from the University of Toronto and Rutgers University have mimicked the explosion of a supernova in miniature. A supernova is an exploding star. In a certain type of supernova, the detonation starts with a flame ball buried d...

Study improves accuracy of models for predicting ozone levels in urban...

A team of scientists has, for the first time, completely characterized an important chemical reaction that is critical to the formation of ground-level ozone in urban areas. The team's results indicate that computer models may be underestimating ozo...

Brown University chemists simplify biodiesel conversion

PROVIDENCE, R.I. [Brown University] -- As the United States seeks to lessen its reliance on foreign oil, biodiesel is expected to play a role. According to the National Renewable Energy Laboratory, a branch of the Department of Energy, biodi...

Powerful supercomputer peers into the origin of life

Supercomputer simulations at the Department of Energy's Oak Ridge National Laboratory are helping scientists unravel how nucleic acids could have contributed to the origins...

Researchers Turn Off Severe Food Allergies in Mice

Johns Hopkins scientists have discovered a way to turn off the immune system’s allergic reaction to certain food proteins in mice, a discovery that...

UCLA physicists control chemical reactions mechanically

UCLA physicists have taken a significant step in controlling chemical reactions mechanically, an important advance in nanotechnology, UCLA physics professor Giovanni Zocchi and colleagues report. Chemical reactions in the cell are catalyzed by e...

MIT researchers create new self-assembling photovoltaic technology that repairs itself

CAMBRIDGE, Mass. -- Plants are good at doing what scientists and engineers have been struggling to do for decades: converting sunlight into stored energy, and doing so reliably day after day, year after year. Now some MIT scientists have succe...
