Cellular traffic: Modeling shows that factors beyond crowding affect how molecules interact within cells

(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.
