N2 - Living liquid crystals: One of very few experimental models to study non-equilibrium dynamic systems • Two-steps transition from a uniform equilibrium "dead" nematic to non-equilibrium living nematic: first to banding/stripe instability, then to topological turbulence with nucleating and annihilating pairs of disclinations • Director guides bacteria along predesigned trajectory • Bacterial velocity in LC is of the same order of magnitude as in water, despite 3,000 higher viscosity; broader distribution of velocities in LCLC potentially associated with the director relaxation • Attractive interactions: Side-by-side in planar cells and end-to-end in homeotropic cells • Fluid jets concentrated and extended by LC along the axis of the bacteria; as a result, bacteria can transport cargo.
