Newly identified genetic marker involved in aggressive Alzheimer's disease
— 10:08 GMT | HealthA gene variation that appears to predict the rate at which Alzheimer's disease will progress has been uncovered by an international team of Alzheimer's disease experts, led by Washington University School of Medicine in St. Louis. Published in the open-access journal PLoS Genetics, the findings help determine how rapidly Alzheimer's patients may develop full-blown dementia after their diagnosis…
'Nanosprings' offer improved performance in biomedicine, electronics
— 10:08 GMT | TechnologyResearchers at Oregon State University have reported the successful loading of biological molecules onto 'nanosprings' - a type of nanostructure that has gained significant interest in recent years for its ability to maximise surface area in microreactors…
Avoiding dangerous climate change: An international perspective
— 10:08 GMT | EnvironmentThe world will need to make substantial reductions in greenhouse gas emissions below current levels over the next few decades if the worst impacts of dangerous climate change are to be avoided. This was a key conclusion from UK and US climate scientists at an international workshop on the UK AVOID program in Washington, DC exploring the most policy-relevant aspects of understanding dangerous climate change…
MIT researchers discover an unexpected twist in cancer metabolism
— 10:08 GMT | HealthIn a paper appearing in the Sept. 16 online edition of Science, Matthew Vander Heiden assistant professor of biology and member of the David H. Koch Institute for Integrative Cancer Research at MIT and researchers at Harvard University report a previously unknown element of cancer cells' peculiar metabolism. They found that cells can trigger an alternative biochemical pathway that speeds up their metabolism and diverts the byproducts to construct new cells…
Cardiac imaging breakthrough developed at the University of Western Ontario
— 10:08 GMT | HealthCardiologists and surgeons may soon have a new tool to improve outcomes for patients requiring pacemakers, bypass surgery or angioplasties. Research led by Dr James White and his colleagues at The University of Western Ontario has led to a new imaging technique, which provides a single, 3D high-resolution image of the heart revealing both its vasculature and the presence of scar tissue within the muscle. This novel imaging was performed using a 3-Tesla MRI at Western's Robarts Research Institute. The findings are published on-line in the Journal of the American College of Cardiology: Cardiovascular Imaging…
Placebo effect significantly improves women's sexual satisfaction, study shows
— 10:08 GMT | HealthMany women with low sex drives reported greater sexual satisfaction after taking a placebo, according to new psychology research from The University of Texas at Austin and Baylor College of Medicine…
Fat stem cells safe for breast reconstruction when cancer is dormant, says Pitt team
— 10:08 GMT | HealthFat-derived stem cells can be safely used to aid reconstruction of breast tissue after mastectomy as long as there is no evidence of active cancer, according to researchers at the University of Pittsburgh School of Medicine. Their findings are available in Tissue Engineering Part A…
Fast-track gene-ID method speeds rare disease search
— 10:05 GMT | HealthA University of Michigan-led research team has identified a gene responsible in some families for a devastating inherited kidney disorder, thanks to a new, faster method of genetic analysis not available even two years ago. The success offers hope that scientists can speed the painstaking search for the genes responsible for many rare diseases and test drugs to treat them…
Tornado-chasing becomes vacation choice, MU researchers find
— 10:02 GMT | EnvironmentInstead of heading to the coast for vacation, people are travelling to Tornado Alley. The number of people registering to get a closer look at tornadoes is growing as vacationers trade in their beach towels for a ride with storm chasers. Labelled 'Tornado Tourists' by a University of Missouri research team, these travellers are searching for an experience beyond just thrills…
