We study the spatiotemporal patterns that emerge when an active nematicfilm of microtubules and molecular motors is encapsulated within a shape-changing lipid vesicle. Unlike in equilibrium systems, where defects are largely static structures, in active nematics defects move spontaneously and can be described as self-propelled particles. The combination of activity, topological constraints and vesicle deformability produces a myriad of dynamical states.","authors_text":"Andreas R. Bausch, Etienne Loiseau, Felix C.
