Humans have long turned to the dog for its nose,especially in its ability to hunt, track missing people, and searchfor drugs- But there is a new challenge： Bomb-detecting dogs now have to learn to find the increasingly common Improvised Explosive Devices (IEDs)(临时组装的爆炸装置） that can be assembledfrom materials not dangerousby themselves.“ So we’ re now asking dogs not just to find a needlein ahaystack (干草堆）一 now the problem is more like saying to the dog we needyou to find any sharpobject in the haystack, ” says Clive Wynne，a professor atArizona State University.
Wynne directs the study that develops methods to train dogs to identify a wide variety of ingredients that could be usedto make bombs. The dogs not only have to detect whether explosive materials are present,they also have to determine if the chemicals they smell could combine to form. an explosive mixture. The dogs needto learn that when combined with other elements, even sugar could be usedin abomb. “ we want the dogs to grasp the concept of ‘ this might explode ’”.
Wynne says the big problem is that IEDs arejust that---improvised and completely unsteady.A dog ’s nose canbe over a thousand times more powerful than a human ’s nose. Some agenciesspent billions of dollars over the last 15 yearstrying to createatechnical replacement for the noseof the dog, and at the end of all that they just had to admit “ No, we cannot get close ”. Wynne thinks his team candevelop bomb sniffing (嗅，闻）dogsthat can detect IEDs at a small part of that price. All it takes is patience.
