In an effort to ferret out those trying to carry and conceal hidden bombs, drugs or other suspect materials, one Israeli company claims they have trained mice to sniff out any potential threats.

BioExplorers have developed a system where a person is hit by a small blast of air that is immediately pushed into a chamber where eight mice are waiting. The mice then smell the air for potentially hazardous or incendiary materials. They can even detect money.

If the person is a threat, the mice reportedly know to gather in a separate compartment as a means of alerting humans, AFP News learned.
