By swimming together, [bacteria] can generate forces in the fluid that are large enough to counterbalance friction, such that the bacterial suspension behaves as a superfluid.
"While this phenomenon has been observed experimentally, a detailed theory about how it works has been missing," says Dr. Aurore Loisy, Research Associate in Applied Mathematics & Theoretical Physics at the University of Bristol.
