UAB scientists discover the origin of a mysterious physical force

...llege London have studied this mysterious force in detail and have discovered where its origins lie. In the same way that a flag flutters in the direction the wind is blowing, at a microscopic level water molecules are gently attracted towards the direction in which an electric field is pointing. However, ...
