(Independent-UK) Simon Calder - The Israeli security firm X-Test claims that mice can detect explosives far more effectively than humans, dogs or machines. Airport security checkpoints of the future may deploy small, furry creatures to trap terrorists. The firm's vice-president, Yuval Amsterdam, is a former bomb-disposal expert for the Israel Defense Forces. He says mice "are as good as dogs as far as their ability to sense, but they're smaller and easier to train. They're cheap, and you don't have to take them for a walk," he added. "Once they are trained, they become bio-sensors."
