| 3. | Mechanism uncovered behind Salmonella virulence and drug susceptibility (Thu, 29 Jul 2010 00:00:00 EDT)
(University of Washington) Researchers have discovered a novel mechanism in Salmonella that affects is virulence and its susceptibility to antibiotics. The mechanism changes the bacteria's production of proteins in a previously unheard of manner. It allows Salmonella to selectively change its levels of certain proteins to respond to inhospital conditions. Although the mechanism had not been recognized before, scientists found evidence of a similar mechanism in all five kingdoms of life. The mechanism appears to have been conserved throughout the course of evolution. |

| 4. | Resting brain activity associated with spontaneous fibromyalgia pain (Thu, 29 Jul 2010 00:00:00 EDT)
(Wiley-Blackwell) A recent study from researchers at Massachusetts General Hospital and University of Michigan provides the first direct evidence of linkage between elevated intrinsic (resting-state) brain connectivity and spontaneous pain intensity in patients with fibromyalgia. This research shows an interaction of multiple brain networks, offering greater understanding of how pain arises. Details of the study appear online and in the August issue of Arthritis & Rheumatism, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology. |

| 7. | Memory's master switch (Thu, 29 Jul 2010 00:00:00 EDT)
(American Friends of Tel Aviv University) A new study led by Dr. Inna Slutsky of Tel Aviv University describes GABA (γ-Aminobutyric acid), a natural molecule that occurs in the brain, which could be the main factor in regulating how many new memories we can generate. The understanding of these mechanisms might lead to the development of new memory enhancers and new treatments for neurodegenerative diseases such as Alzheimer's. |

(Tufts University) Tougher than a bullet-proof vest yet synonymous with beauty and luxury, silks spun by worms and spiders are a masterpiece of nature whose properties have yet to be fully replicated in the laboratory. But scientists have begun to unravel the secrets of silk. Tufts biomedical engineers report that silk-based materials have been transformed from commodity textile to a growing web of high tech applications. |

(Carnegie Mellon University) Carnegie Mellon University has developed a new fluorescent biosensor that could aid in the development of an important class of drugs that target a crucial class of proteins called G protein-coupled receptors (GPCRs). GPCRs are popular drug targets because of the pivotal role they play in cells' communication circuits responsible for regulating functions critical to health, including circuits involved in heart and lung function, mood, cognition and memory, digestion and the inflammatory response. |
