The cover illustration is a stylized image, with a field of view of several millimetres, of cyclic AMP waves in populations of the single-cell micro-organism Dictyostelium discoideum on the surface of agar. These waves are 'target patterns' driven by pacemaker cells at their centres. Targets compete with rotating spirals during the stage of the life cycle of Dictyostelium in which travelling chemical waves induce chemotaxis towards wave centres and result in multicellular structures. We discuss recent progress in the study of this competition.
