Three Penn State researchers have shown that certain combinations of elemental atoms have electronic signatures that mimic the electronic signatures of other elements. According to the team's leader A. Welford Castleman Jr., Eberly Distinguished Chair in Science and Evan Pugh Professor in the Departments of Chemistry and Physics, "the findings could lead to much cheaper materials for widespread applications such as new sources of energy, methods of pollution abatement, and catalysts on which industrial nations depend heavily for chemical processing." http://www.physorg.com/news181225307.html Physics Mon, 28 Dec 2009 15:00:12 EST news181225307 Just like teenagers at a prom, proteins are tended by chaperones whose job it is to prevent unwanted interactions among immature clients.

It's Latin for "solid Earth." Most of the time, at least from our perspective here on the ground, Earth seems to be just that: solid. Yet the Earth beneath our feet is actually in constant motion. It moves through time and space, of course, along with the other objects in the universe, but it moves internally as well. http://www.physorg.com/news181194545.html Space & Earth Mon, 28 Dec 2009 03:50:49 EST news181194545 A sudden worldwide increase in an antibiotic-resistant bacterium is cause for concern, according to a review in f1000 Medicine Reports. http://www.physorg.com/news180933360.html Medicine & Health Mon, 28 Dec 2009 03:50:05 EST news180933360 The premise that hunger makes food look more appealing is a widely held belief - just ask those who cruise grocery store aisles on an empty stomach, only to go home with a full basket and an empty wallet. http://www.physorg.com/news181194023.html Medicine & Health Mon, 28 Dec 2009 03:41:16 EST news181194023 Using disinfectants could cause bacteria to become resistant to antibiotics as well as the disinfectant itself, according to research published in the January issue of Microbiology.
