12:00 AM Carnegie Mellon researchers create fluorescent biosensor to aid in drug development
(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. |

12:00 AM Study finds respiratory symptoms more reliable indicator of H1N1, not fever alone
(Elsevier Health Sciences) New research shows that individuals with mild H1N1 infection may go undetected using standard diagnostic criteria, according to a study in the August issue of the American Journal of Infection Control, the official publication of the Association for Professionals in Infection Control and Epidemiology. The study concludes that coughing or other respiratory symptoms are more accurate in determining influenza infection than presence of a fever. |

12:00 AM Small increases in vaccine cost can cause large gaps in protection
(Harvard University) Public immunization efforts may be much more sensitive than previously realized to small changes in the perceived costs or risks of vaccination, scientists at Harvard University report this week. In some cases, the spread of vaccine avoidance via social networks can make the difference between a minor, localized outbreak and an epidemic four times as large. |

12:00 AM A breakthrough in tuberculosis research
(McGill University) The key to the fate of the macrophages is the balance between two kinds of eicosanoids. Eicosanoids are molecules that contribute to the control of our immune system. The genetic code of TB bacteria enables it to tip this balance in favor of necrosis, and human genetic analysis revealed that modification in eicosanoids production is associated with susceptibility or resistance to TB. Fortunately, drugs that target the production of eicosanoids are already in use for treating other inflammatory diseases, such as rheumatoid arthritis. |

12:00 AM Western diet link to ADHD
(Research Australia) A new study from Perth's Telethon Institute for Child Health Research shows an association between ADHD and a "Western-style" diet in adolescents. The research findings have just been published online in the international Journal of Attention Disorders. Leader of Nutrition studies at the Institute, Associate Professor Wendy Oddy, said the study examined the dietary patterns of 1800 adolescents from the long-term Raine Study and classified diets into 'Healthy' or 'Western' patterns. |

12:00 AM Nanomaterials poised for big impact in construction
(Rice University) Nanomaterials are poised for widespread use in the construction industry, where they can offer significant advantages for a variety of applications ranging from making more durable concrete to self-cleaning windows. But widespread use in building materials comes with potential environmental and health risks when those materials are thrown away. Those are the conclusions of a new study published by Rice University engineering researchers this month in ACS Nano. |

12:00 AM Why fad diets work well for some, but not others
(Genetics Society of America) Using fruit flies, researchers have found that genes interacting with diet, rather than diet alone, are the main cause of variation in metabolic traits, such as body weight. This helps explain why some diets work better for some people than others, and suggests that future diets should be tailored to an individual's genes rather than to physical appearance. |

12:00 AM Electronic cigarettes require more suction than conventional brands
(University of California - Riverside) Stronger suction is required to smoke "electronic cigarettes" than conventional brands, with possible adverse effects on human health, researchers at the University of California, Riverside report. Using a smoking machine to compare the smoking properties of eight conventional cigarettes with five e-cigarette brands, the researchers also found that in the case of e-cigarettes, the aerosol density dropped after the first ten puffs, requiring still stronger suction thereafter to produce aerosol. |
