Mice Trained to Rat on Terrorists (IsraelNationalNews.com) An Israeli start-up uses mice to sniff out explosives at security checkpoints. The company, named BioExplorers, is staffed by IDF Special Forces reservist soldiers and biologists. They say that mice have a keener sense of smell than dogs, and can be trained to identify the odor of explosive material as an unpleasant one.

"Bio Explorers systems are based on combining the hyper- sensitive olfactory capability of rodents with the care-free reliability of a hi-tech machine system," the firm explains on its website. "Many millions of years of evolution made the olfactory system of rodents incredibly sensitive, quick and specific as this is their main sense used for foraging, mating and avoiding predators."
