BioExplorers, an Israeli company, claims they can train mice to sniff out potential bomb threats.
BioExplorers have developed a system in which a human is hit by a small blast of air that is pushed into a chamber containing eight mice.
The mice then smell the air for potentially hazardous materials such as bombs. They can even detect money, reports AFP.
If the person has a bomb, the mice gather in a separate area to warn humans. The mice allegedly have a better sense of smell than dogs, who are traditionally used to sniff out bombs.
BioExplorers founder and chief technology officer Eran Lumbroso recently spoke at the Israel Homeland Security exhibition in Tel Aviv and said: "The idea began in 2000-2001, when there were many suicide bombings on [Israeli] buses. I was in the army at the time, and the idea emerged to use small animals instead of dogs in detecting suicide bombers."
Popular VideoCongress just passed a drug testing law that has a lot of people outraged. Do you think this is wrong?
“The mice can also be easily trained, and thanks to their small size, you can use a small group of them and have multiple sensors."
The mice reportedly work for four hours, then the next mouse shift takes over.
