Squeezing polymers produces chemical energy but raises doubts about implant safety A polymer is a mesh of chains, which slowly break over time due to the pressure from ordinary wear and tear. When a polymer is squeezed, the pressure breaks chemical bonds and produces free radicals: ions with unpaired electrons, full of untapped energy. These molecules are responsible for aging, DNA damage and cancer in the human body. In a new study, Northwestern University scientists turned to squeezed...

Scientists have shown that a new molecule in the earth´s atmosphere has the potential to play a significant role in off-setting global warming by cooling the planet. In a breakthrough paper published in Science, researchers from The University of Manchester, The University of Bristol and Sandia National Laboratories report the potentially revolutionary effects of Criegee biradicals. These invisible chemical intermediates are powerful oxidisers of pollutants such as nitrogen dioxide...

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...
