Mice could soon replace dogs to sniff out bombs, explosives, drugs and even suicide bombers. An Israeli security company has now trained rodents to tip off guards when they detect explosives, drugs and other contrabands, virtually turning them into biological sensors. The security firm called ‘Tamar Group’ is the brainchild of former Israeli special forces officers, who claim that their breakthrough could transform the homeland security market. Boaz Hayun, CEO of the group, was quoted by Daily Mail as saying that mice were eventually chosen over dogs because of their keen noses and diminutive size. “Our system takes animals and turns them into biological sensors, using specially-trained laboratory mice and measuring their reactions to outside stimuli. “They are placed at the entry point in a security checkpoint or installation, and when they detect something that appears suspicious, the sensor records their physical reactions and communicates it to a computer that analyses the data and alerts the security personnel,” he said.
