(PhysOrg.com) -- It is very difficult to overestimate the importance of colloidal suspensions. Besides being an integral part of our everyday life (food, cosmetics, drugs), they also serve as an excellent model system for basic science. http://phys.org/news224932752.html Physics Wed, 18 May 2011 11:10:01 EST news224932752 (PhysOrg.com) -- Using large-scale computer simulations, researchers at the Georgia Institute of Technology have identified the most important factors affecting how molecules move through the crowded environment inside living cells. The findings suggest that perturbations caused by hydrodynamic interactions – similar to what happens when the wake from a large boat affects smaller boats on a lake – may be the most important factor in this intracellular diffusion. http://phys.org/news206085880.html Biology Tue, 12 Oct 2010 07:06:38 EST news206085880
