Two bacterial enzymes confer resistance to common herbicide, say MU researchers
— 10:26 GMT | BiologyIn an article in the Nov. 23 issue of the journal The Proceedings of the National Academy of Science, researchers with Dow AgroSciences and the University of Missouri report on two bacterial enzymes that, when transformed into corn and soybeans, provide robust resistance to the herbicide 2,4-D. The discovery may soon provide Missouri corn and soybean growers a solution to the growing problem of herbicide-resistant weeds…
Scientists find industrial pollutants in Eastern Lake Erie carp
— 10:23 GMT | EnvironmentResearchers from Upstate New York institutions, including the University at Buffalo, have documented elevated levels of two industrial pollutants in carp in eastern Lake Erie, adding to the body of scientific work demonstrating the lasting environmental effects of human activity and waste disposal on the Great Lakes…
Defence mechanism against bacteria and fungi deciphered
— 10:20 GMT | HealthUnder standard laboratory conditions, the human beta-defensin 1 (hBD-1), a human antibiotic naturally produced in the body, had always shown only little activity against microbes. Nevertheless the human body produces it in remarkable quantities. The solution to the puzzle was the investigation process itself, as the research group led by Dr Jan Wehkamp at the Dr Margarete Fischer-Bosch Institute for Clinical Pharmacology of the Stuttgart-based Robert Bosch Hospital found out…
Preventing tooth decay in the youngest American Indians

Researchers discover how to tame hammering droplets
— 10:05 GMT | TechnologyA water hammer can occur when a valve is suddenly opened or closed in a pipe carrying water or steam, causing a pressure wave to travel down the pipe with enough force that it can sometimes cause the pipes to burst. Now, new research shows that a similar effect takes places on a tiny scale whenever a droplet of water strikes a surface…
Mindfulness meditation training changes brain structure in 8 weeks
— 10:02 GMT | HealthParticipating in an 8-week mindfulness meditation program appears to make measurable changes in brain regions associated with memory, sense of self, empathy and stress. In a study that will appear in the January 30 issue of Psychiatry Research: Neuroimaging, a team led by Massachusetts General Hospital (MGH) researchers report the results of their study, the first to document meditation-produced changes over time in the brain's grey matter…
