Super-sniffer mice could detect land mines and decode human olfactory system

Researchers at Hunter College, part of the City University of New York, have created super-sniffer mice that have an increased ability to detect a specific odor, according to a study published July 7 in Cell Reports. The mice, which can be tuned to have different levels of sensitivity to any smell by using mouse or human odor receptors, could be used as land-mine detectors or as the basis for novel disease sensors.
