The authors introduce a method to control swimming bacteria by a liquid crystal environment. The paper shows that a liquid crystal nematic patterned as a spiral vortex causes an individual-to-collective transition as the bacterial concentration increases, in which non-polar swimming of individual bacteria is replaced by a unipolar circular swirling of condensed swarms.
