Animals Focus Smell as Well as Vision

Animals can focus their sense of smell in much the same way as humans focus their eyes, helping them detect predators and search out food. Researchers at the University of Chicago found that rats adjust their sense of smell through sniffing techniques that bring scents to receptors in different parts of the nose. The sniffing patterns changed according to what kind of substance the rats were attempting to detect.
