New Way Deadly Food-borne Bacteria Is Spread A researcher has uncovered a previously unknown mechanism that plays an important role in the spread of a deadly food-borne bacterium. Poxvirus'Ability To Hide From The Immune System May Aid Vaccine Design The cowpox virus, a much milder cousin of the deadly smallpox virus, can keep infected host cells from warning the immune system that they have been compromised, researchers have found. The scientists also showed that more virulent poxviruses, such as the strains of monkeypox prevalent in Central Africa, likely have the same ability. Prenatal Cocaine Exposure Exerts Subtle Effects On Schoolchildren Children exposed to cocaine before birth show subtle but discernible differences in their ability to plan and problem-solve once they reach school age, University of Florida researchers report. Still, most fare far better in the first few years after birth than many experts once predicted. New Neuroimaging Study Identifies 'Brain Signature'For Cigarette Cravi A new brain imaging study shows that cigarette cravings in smokers who are deprived of nicotine are linked with increased activation in specific regions of the brain. Using a novel method of measuring brain blood flow, this study is the first to show how abstinence from nicotine produces brain activation patterns that relate to urges to smoke. Upgrade Your Cable Provider's DVR Your cable provider's DVRs are cheap compared to the alternatives, but the low cost comes at the expense of attractive features like a bigger hard drive. Luckily, with only a little risk, you can upgrade your DVR just like your computer.

 Gene Regions Beyond Protein Instructions Important In Disease Gene hunters at Johns Hopkins have discovered a common genetic mutation that increases the risk of inheriting a particular birth defect not by the usual route of disrupting the gene's protein-making instructions, but by altering a regulatory region of the gene. Although the condition, called Hirschsprung disease, is rare, its complex genetics mimics that of more common diseases, such as diabetes and heart disease. A Kiss Is Still A Kiss -- Or Is It? A new study suggests that men and women's views diverge widely on the significance of a kiss and the kiss can have profound consequences for romantic relationships, and can even be a major factor in ending one. In a recently published article, psychologists reveal that many college students have found themselves attracted to someone, only to discover after they kissed them for the first time that they were no longer interested. In a sample of 1,041 college students, researchers found only five who had never experienced romantic kissing and more than 200 who estimated having kissed more than 20 partners. 'Electronic Nose'Could Detect Hazards A tiny "electronic nose"that MIT researchers have engineered with a novel inkjet printing method could be used to detect hazards including carbon monoxide, harmful industrial solvents and explosives. Led by MIT professor Harry Tuller, the researchers have devised a way to print thin sensor films onto a microchip, a process that could eventually allow for mass production of highly sensitive gas detectors. New Way To Attack Inflammation In Graves' Eye Disease A small group of patients with severe Graves' eye disease experienced rapid improvement of their symptoms -- and improved vision -- following treatment with the drug rituximab. Inflammation around their eyes and damage to the optic nerve were significantly reduced. The same patients had not previously responded to steroids, a common treatment for Graves' eye disease. Engineers Designing Protective Wall To Shield Bridges From Terrorist A Government officials have acknowledged the transportation system's vulnerability to terrorist attacks. Bridges are among the most vulnerable. Because of this reality, researchers at the University of Missouri-Columbia are working with federal highway officials to develop a new technology that can protect bridges against such attacks.
