Neutron scattering reveals extremely slow water in Dead Sea organism
— 17:45 GMT | BiologyExperiments carried out at the Institut Laue Langevin (ILL), in Grenoble, have led to the discovery of a new type of water behaviour within the cells of ancient organisms that live in the saturated salt waters of the Dead Sea…
Safer and more effective way to treat Crohn's disease
— 17:45 GMT | HealthAn international research study, published in The Lancet, has thrown into question the current method of treating Crohn's disease - opening the door to a safer and more effective treatment option for sufferers of the chronic disease…
Ingredient in yellow curry can reduce heart enlargement and may prevent heart failure
— 17:45 GMT | HealthEating curcumin, a natural ingredient in the spice turmeric, may dramatically reduce the chance of developing heart failure, researchers at the Peter Munk Cardiac Centre of the Toronto General Hospital have discovered…
New acute lung injury study finds benefits of autologous cell transplantation therapy
— 17:45 GMT | HealthA study published in this month's Anesthesiology highlights the potential of cell-based therapies for the treatment of acute lung injury and acute respiratory distress syndrome (ARDS). This discovery may represent a milestone in acute lung injury therapy, which is based on removing and then reintroducing cells from the same individual…
Modified electron microscope identifies atoms
— 17:45 GMT | PhysicsA new electron microscope recently installed in Cornell's Duffield Hall is enabling scientists for the first time to form images that uniquely identify individual atoms in a crystal and see how those atoms bond to one another. And in living colour…
Bacteria and nanofilters - the future of clean water technology
— 17:45 GMT | EnvironmentBacteria often get bad press, with those found in water often linked to illness and disease. But researchers at The University of Nottingham are using these tiny organisms alongside the very latest membrane filtration techniques to improve and refine water cleaning technology…
Astronomers discover largest-ever dark matter structures spanning 270M light-years
— 17:33 GMT | AstronomyA University of British Columbia astronomer with an international team has discovered the largest structures of dark matter ever seen. Measuring 270 million light-years across, these dark matter structures criss-cross the night sky, each spanning an area that is eight times larger than the full moon…
Novel link between excessive nutrient levels and insulin resistance
— 17:33 GMT | HealthFor quite some time now, scientists suspected the so-called hexosamine pathway - a small side business of the main sugar processing enterprise inside a cell - to be involved in the development of insulin resistance. But they could never quite put their finger on the underlying mechanism…
Genetic tags reveal secrets of memories' staying power in mice
— 17:33 GMT | HealthA better understanding of how memory works is emerging from a newfound ability to link a learning experience in a mouse to consequent changes in the inner workings of its neurones. Researchers, supported in part by the National Institutes of Health's National Institute of Mental Health (NIMH), have developed a way to pinpoint the specific cellular components that sustain a specific memory in genetically-engineered mice…
New devices less effective in thwarting brain aneurysm recurrence
— 17:33 GMT | HealthA retrospective analysis of 100 patients suffering from a ruptured brain aneurysm has found that expensive new coiling devices are no more effective than bare platinum coils at preventing aneurysms from recurring…
