So a fish gets on a treadmill…sounds like the beginning of a joke right? It is not; it is actually a new study in the fight to cure deafness.

Scientists start with a tank, add a current, some cylinders to create turbulence, a laser and a mirror to visualize the invisible currents, and of course fish and voila, a fish treadmill. As it turns out zebra fish can shut down all muscles and surf the eddies the turbulence creates. How do they do this? By a cluster of hair cells called the lateral line system that can detect the flow of water over their bodies. These hair cells are almost identical to human hair cells in the inner ear. Basically learning how a fish swims help scientists better understand how we hear. Click below to read more on this new research.
