  Sniffing Dog Provides Cost-Effective Contamination Detection

  America's only dog that's trained to sniff mercury is able to detect as little as a half-gram, and is faster and cheaper than traditional lab analysis. Dogs' olfactory membranes are larger and 44 ... > more

  Mimicking Insects to Avoid Sinking Using Surface Tension

  A new robot made of ultralight carbon-fiber can stand or slowly walk on water. The principle it uses is borrowed from insects -- surface tension tends to prevent the water's surface from breaking, ... > more

  Entomologists Train Insects to Act Like Sniffing Dogs

  If rewarded with sugary water, wasps can be trained in minutes to follow specific smells. The olfactory sensors in their antennae can sense chemicals in the air in concentrations as tiny as a few ... > more
