Making sure the internet delivers European researchers have developed affordable test suites that businesses can use to check whether their software will work with the next-generation internet. Mother's vitamin D status during pregnancy will affect her baby's dental health Low maternal vitamin D levels during pregnancy may affect primary tooth calcification, leading to enamel defects, which are a risk factor for early-childhood tooth decay. Mimic molecules to protect against plague Bacteria that cause pneumonic plague can evade our first-line defences, making it difficult for the body to fight infection. In fact, a signature of the plague is the lack of an inflammatory response. Now, scientists have discovered a way to protect against death following infection with plague bacteria, by using molecules that can mimic the pathogens. According to research published in the July issue of Microbiology, these molecules make antibiotics more effective and can even be used to protect against other diseases. Malaria on the increase in the UK A huge rise in the numbers of UK residents travelling to malaria endemic areas, combined with a failure to use prevention measures, has significantly increased cases of imported falciparum malaria in the UK over the past 20 years, according to a study published on BMJ.com. Workers scramble to clear embarrassing algae sludge China scrambled Thursday to clear tonnes of algae that is covering a third of the Olympic sailing course and causing huge embarrassment for authorities trying to promote a "Green Games." Some psych patients wait days in hospital ERs (AP) -- When staffers at a Brooklyn hospital spotted a middle-aged woman lying face-down on a waiting room floor last month, it hardly seemed like cause for alarm. New study points to agriculture in frog sexual abnormalities A farm irrigation canal would seem a healthier place for toads than a ditch by a supermarket parking lot. But University of Florida scientists have found the opposite is true. In a study with wide implications for a longstanding debate over whether agricultural chemicals pose a threat to amphibians, UF zoologists have found that toads in suburban areas are less likely to suffer from reproductive system abnormalities than toads near farms - where some had both testes and ovaries. Prevalence of religious congregations affects mortality rates LSU associate professor of sociology Troy C. Blanchard recently found that a community's religious environment - that is, the type of religious congregations within a locale - affects mortality rates, often in a positive manner. These results were published in the June issue of Social Forces, a leading journal in the field of sociology. Ridding meat of E. coli You may be able to enjoy a rare hamburger soon, thanks to a discovery made by a team of University of Alberta researchers. Resveratrol found to improve health, but not longevity in aging mice on standard diet Scientists have found that the compound resveratrol slows age-related deterioration and functional decline of mice on a standard diet, but does not increase longevity when started at middle age. This study, conducted and supported in part by the National Institute on Aging (NIA), part of the National Institutes of Health, is a follow-up to 2006 findings that resveratrol improves health and longevity of overweight, aged mice. The report confirms previous results suggesting the compound, found naturally in foods like grapes and nuts, may mimic, in mice, some of the effects of dietary or calorie restriction, the most effective and reproducible way found to date to alleviate age-associated disease in mammals. ... |
