| 4. | Talented bacteria make food poisoning unpredictable (Sun, 05 Sep 2010 00:00:00 EDT)
(Society for General Microbiology) While we are often exposed to bacteria in our food which could cause food poisoning, we don't always become ill -- why should this be so? Professor Colin Hill who is presenting his work at the Society for General Microbiology's autumn meeting in Nottingham today describes how bacteria use different tricks to aid their survival inside the body, helping to explain why food poisoning can be so unpredictable. |

| 5. | Backstabbing bacteria: A new treatment for infection? (Sun, 05 Sep 2010 00:00:00 EDT)
(Society for General Microbiology) Selfish bacterial cells that act in their own interests and do not cooperate with their infection-causing colleagues can actually reduce the severity of infection. The selfish behaviour of these uncooperative bacteria could be exploited to treat antibiotic-resistant infections, according to research being presented at the Society for General Microbiology's autumn meeting today. |

| 10. | MIT moves toward greener chemistry (Fri, 03 Sep 2010 00:00:00 EDT)
(Massachusetts Institute of Technology) Phosphorus, a mineral element found in rocks and bone, is a critical ingredient in fertilizers, pesticides, detergents and other industrial and household chemicals. Once phosphorus is mined from rocks, getting it into these products is hazardous and expensive, and chemists have been trying to streamline the process for decades. |

| 13. | Magnetism's subatomic roots (Fri, 03 Sep 2010 00:00:00 EDT)
(Rice University) Theoretical physicists from Rice University have created a new model that helps define the subatomic origins of ferromagnetism -- the everyday "magnetism" of compass needles and refrigerator magnets. The model, which is detailed in a new paper in the Proceedings of the National Academy of Sciences, was created to explore the inner workings of ferromagnetic compounds that are related to high-temperature superconductors. |

| 18. | UCLA chemists, engineers achieve world record with high-speed graphene transistors (Thu, 02 Sep 2010 00:00:00 EDT)
(University of California - Los Angeles) A UCLA team led by Xiangfeng Duan has developed a new fabrication process for high-speed graphene transistors using a nanowire as the self-aligned gate. This new technique does not produce any appreciable defects in the graphene during fabrication, so the carrier mobility is retained. Also, by using a self-aligned approach with a nanowire as the gate, the group was able to overcome alignment difficulties previously encountered and fabricate short channel devices with unprecedented performance. |
