Reining In a Chaotic Fluid

Reining In a Chaotic FluidFluid flows mimicking biological flows can be controlled in the lab using a feedback system, which could be useful in robotics and other technologies. By Mark BuchananO rdinary fluids can flow when driven by pressure or gravity, but biological fluids, such as those inside cells, generate complex flows through internal sources of chemical energy.Flows of such "active fluids" could be extremely useful in robotics and other areas of engineering, but controlling them remains difficult.Now researchers have
