Scientists bioengineer a cellular speedometer

Researchers have discovered that Pseudomonas bacteria can detect the speed (shear rate) of flow regardless of the force. By linking the flow-detecting gene to one responsible for illumination, they have bioengineered a real-time visual speedometer: The faster the flow, the brighter the glow.
