New publication: "Active colloids in liquid crystals" by Oleg D. Lavrentovich. Click here to download the full article. Highlights: Liquid crystals enable electrokinetics with the velocity proportional to the field squared, Director distortions generate space charge in the presence of an electric field, Brownian motion in a liquid crystal is both anisotropic and anomalous, Bacterial trajectories in liquid crystals are controlled by the director, Living liquid crystals feature periodic band instability and topological turbulence.
