"The disease typically results in a significant deterioration in quality of life for those with the illness and their families, and costs the Australian community around $2.5 billion dollars a year indirectly.

...ch as are present in high-fructose corn syrup. The results suggest that while appetite and food intake are influenced by the number of calories consumed earlier, the types of sugars consumed in those calories seem to make little or no difference. Some companies have made a sincere effort to put sucrose back...Scientists find brown fat master switch
...ed those cells to generate brown fat cells. "These results illustrate that the gene we identified can turn on a broad program of brown fat cell development when we insert it into precursors that otherwise would produce white fat," Spiegelman added. Lead author on the paper is Patrick Seale, PhD, in the Spieg...Mild stress in the womb may worsen risk of cerebral palsy
...l disabilityaccording to new research in mice. The results may be the first to demonstrate such effects of stress on animals in the womb. The new study, led by Pierre Gressens, MD, PhD, of Inserm in France, used a mouse model to test whether exposure to minimal but repeated stress throughout gestation woul...A first-principles model of early evolution

...d risk of ER+ breast cancer among these women. The results showed no overall association of breast cancer risk with the vegetable-soy pattern. Our study suggests the possibility that the meat-sweet pattern interacts with obesity to increase breast cancer risk, Tseng said. Low consumption of a western di...Piecing together the cyanobacteria puzzle

You can use this technology to look at things going on inside the cell, he said. This is going to change the way that w...Study provides new data about the laws governing embryo development in organisms

The results have enabled them to identify the most important system parameters and showed that the biological mechanism maintained its functionality in 91% of the cases analyzed. According to Miln and Buceta this study confirms the hypothesis that if this gene n...Fat horses face health problems

Thatcher and his colleagues believe the study results suggest that horse-owners should change some of the ways in which they care for their horses and hinted that horses could emerge as an important model for studying the health implications of human obesity. Obesity, over the past decade, has become...MIT, BU team builds viruses to combat harmful 'biofilms'

Our results show we can do simple things with synthetic biology that have potentially useful results, says first author Timothy Lu, a doctoral student in the Harvard-MIT Division of Health Sciences and Technology. Bacterial biofilms can form almost anywhere, e...New way to target and kill antibiotic-resistant bacteria found

The Italian family had no cases with two copies of the mutated gene. We would have expected to see cases with two copies of the mutate...Scientists follow familiar TRAIL to new cancer therapy

Taken together, results from these studies indicate that formation of higher-order homotetrameric complexes and recruitment of RXR are essential components of RARA-induced transformation and that RXR is a key member of the PML/RARA-associated oncogenic response that facilit...Penn researchers discover how microRNAs control protein synthesis
