Bed rest can harm, instead of help, in pregnancy complications, research suggests (October 29, 2010) -- Bed rest may not be the best option for preventing preterm labor and may even cause harm to the mother and baby, according to an integrative literature review. ... > full story
Three-dimensional maps of brain wiring (October 29, 2010) -- Scientists have developed a software tool that physicians can use to easily study the wiring of the brains of their patients. The tool converts MRI scans using special techniques to three-dimensional images. This now makes it possible to view a total picture of the winding roads and their contacts without having to operate. ... > full story
Researchers use math, maps to plot malaria elimination plan (October 29, 2010) -- An international team of researchers has used mathematical models and maps to estimate the feasibility of eliminating malaria from countries that have the deadliest form of the disease. ... > full story
Most preschool-age children exceed daily screen time recommendations, new study suggests (October 29, 2010) -- The American Academy of Pediatrics recommends that parents limit combined screen time from television, DVDs, computers and video games to two hours per day for preschool-age children. In a study soon to be published, researchers found that many children are exposed to screen time both at home and while at child care, with 66 percent exceeding the recommended daily amount. ... > full story
Is the shape of a genome as important as its content? (October 29, 2010) -- The complex associations between genes may be defined in part by the three-dimensional structure of the all of the chromosomes form together: the shape of the genome, according to researchers. By mapping out the structure of the fission yeast genome, they demonstrate how this non-random arrangement positions groups of genes together. This structure is not merely the shape of the genome, but also a key to how it works. ... > full story
Researchers build colony of colon cancer stem cells to test new approach to therapy (October 29, 2010) -- Researchers have devised a three-dimensional system in laboratory culture that mimics the growth patterns of colon cancer stem cells in patients. The assay, which uses green fluorescent "reporter" proteins to watch the process of stem cell differentiation, is designed to understand how these cancer stem cells behave, and to identify and test therapies that could halt production of the endless generations of new cancer stem cells that continually revive a tumor. ... > full story
Cancer: Key mechanism in the control of cell motility revealed (October 29, 2010) -- Scientists have identified a novel molecular mechanism in the control of cell motility. This research could eventually lead to the development of new cancer-treating drugs that could block the spread of tumors (metastasis). ... > full story
Not putting the clocks back this weekend would improve health, says expert (October 29, 2010) -- Not putting the clocks back this weekend but still putting them forward in the spring would be a simple and effective way to vastly improve our health and well-being, says an expert in the online British Medical Journal. ... > full story
Scientists uncover evolution of new virus, closely related to poliovirus (October 29, 2010) -- Scientists have completed the first major review of diagnostic methods and treatments for a rapidly evolving virus that causes hand, foot and mouth disease in children. The virus, called enterovirus 71, is closely related to poliovirus, and was first detected in California in the 1960s. Since then the virus has spread across Asia, affecting mostly children and some adults. Serious cases of the disease can include neurological disorders such as meningitis, paralysis and encephalitis. ... > full story
Organic solvent system may improve catalyst recycling and create new nanomedicine uses (October 29, 2010) -- Noble metals such as platinum and palladium are becoming increasingly important because of growth in environmentally friendly applications such as fuel cells. A new solvent system could improve the recycling of these metals. ... > full story
Olive oil protects liver from oxidative stress, rat study finds (October 29, 2010) -- Extra-virgin olive oil can protect the liver from oxidative stress. Researchers exposed rats to a moderately toxic herbicide known to deplete antioxidants and cause oxidative stress, finding that those rats fed on a diet containing the olive oil were partially protected from the resulting liver damage. ... > full story
Tighter regulations recommended on food advertisements during children's TV viewing times (October 29, 2010) -- Psychologists have called for tighter advertising regulations after a study revealed unhealthy foods are more likely to be advertised during children's peak viewing times than at any other point in the broadcasting schedule. ... > full story
