bomb-sniffing bees

"LOS ALAMOS, NM - NOVEMBER 30: Tim Haarmann, principle investigator with the Stealthy Insect Sensor Project at Los Alamos National Laboratory, checks on his bomb-sniffing honey bees November 30, 2006 at Los Alamos National Laboratory in Los Alamos, New Mexico. Using Pavlovian-like techniques, researchers are taking advantage of the bees' keen sense of smell and their love of nectar to produce weapons in the war on terror." (from here)
