Wasps Better Than Dogs At Sniffing Out Bombs
boinx writes "Researchers have found that certain wasps can be trained in a matter of minutes to detect the odoriferous substance of your choice. All it takes is a PVC pipe, some wasps and a webcam. Check it out."
Similar stories have been reported in places like New Scientist (best example I could find at the moment) for several years. Often they just come to a conclusion that dogs, once trained, are far easier to handle than wasps and live a lot longer.
