Biologically active fluids, such as bacterial suspensions or cytoskeletal extracts with molecular motors and ATP, are a source of intriguing problems in the physics of complex fluids. They are composed of particles that with internal machinery that take up energy from their surroundings and actively move the surrounding medium. My talk will review recent results on thin fluid films and drops of active fluids, and possibly the dynamics of a single stiff filament in an active film.
