The actin cytoskeleton of eucaryotic cells undergoes constant remodeling. To shed light on the principles governing such dynamic reorganizations, a reconstituted active actin network is introduced. The structure formation in this minimal model system is the result of an intricate interplay of force exertion by motor filaments and the degree of connectivity in the network: a superdiffusive behavior, which is reminiscent of the intracellular dynamics in living cells, occurs only if these parameters are balanced.      «
