The formation of patterns is a universal phenomenon that underlies fundamental processes in biology. An example are the concentration patterns of proteins, which direct vital cellular processes, including cell division, polarity, and movement. These protein patterns arise from the interplay of chemical reactions and the spatial transport of proteins. Transport can occur either passively (through diffusion) or actively (through flows). Unlike diffusion, transport by flows exhibits a clear preferred spatial direction.
