In a breakthrough paper published in this week's issue of Science magazine, researchers from Sandia's Combustion Research Facility, the University of Manchester and Bristol University report direct measurements of reactions of a gas-phase Criegee intermediate using photoionization mass spectrometry. (visit www.youtube.com/SandiaLabs to see a short video of Sandia combustion chemists discussing the research.) Criegee intermediates — carbonyl oxides — are implicated in...

Feedback mechanism coordinates cellular respiration and the degradation of free oxygen radicals Oxygen-consuming organisms obtain energy through cellular respiration, which is the transformation of carbohydrates and oxygen into carbon dioxide and water. This process also produces toxic oxygen radicals which must be decomposed immediately, as they would otherwise cause damage to cells. Scientists from the Max Planck Institute for Molecular Genetics in Berlin have now discovered a mechanism,...

Obesity is growing at alarming rates worldwide, and the biggest culprit is overeating. In a study of brain circuits that control hunger and satiety, Yale School of Medicine researchers have found that molecular mechanisms controlling free radicals–molecules tied to aging and tissue damage–are at the heart of increased appetite in diet-induced obesity. Published Aug. 28 in the advanced online issue of Nature Medicine, the study found that elevating free radical levels in the...

Nitrogen-containing soil is a source of hydroxyl radicals that remove pollutants from the atmosphere Eutrophication harms the environment in many ways. Unexpectedly, nitrogen fertilizer may also be positive for the environment. And even acidic soils, promoting the destruction of forests, can have a positive effect. Researchers from the Biogeochemistry Department at the Max Planck Institute for Chemistry in Mainz found out that nitrogen fertilizer indirectly strengthens the self-cleaning...

Bitter cumin is used extensively in traditional medicine to treat a range of diseases from vitiligo to hyperglycemia. It is considered to be antiparasitic and antimicrobial and science has backed up claims of its use to reduce fever or as a painkiller. New research published in BioMedCentral's open access journal BMC Complementary and Alternative Medicine shows that this humble spice also contains high levels of antioxidants. Reactive oxygen species (ROS), also known as free radicals, are...

New method allows for more precise control over ATRP, a popular technique used for creating specialized plastics Scientists led by Carnegie Mellon University chemist Krzysztof Matyjaszewski are using electricity from a battery to drive atom transfer radical polymerization (ATRP), a widely used method of creating industrial plastics. The environmentally friendly approach, reported in the April 1 issue of Science, represents a breakthrough in the level of control scientists can achieve over the...

Fear of free radicals may be exaggerated, according to scientists from Karolinska Institutet. A new study, published in The Journal of Physiology, shows that free radicals act as signal substances that cause the heart to beat with the correct force. Free radicals are molecules that react readily with other substances in the body, and this can have negative effects on health in certain circumstances, through the damage caused to cells. Free radicals can be counteracted by substances known as...
