"The wandering spider boasts one of the world’s most sensitive vibration detectors: It can pick up the slightest rustling of a leaf from several meters away. Now, scientists have developed similar sensors that can detect simple human speech. The technology could lead to wearable electronics for speech recognition, health monitoring, and more."

A new nanotechnology device mimics a dog’s nose so closely that it can detect explosives and other substances. According to ScienceDaily, their goal is to make “portable, accurate, and highly sensitive” explosive-sniffing devices that “could become as commonplace as smoke detectors in public places.”

"A fruit fly's sense of smell could potentially be used to sniff out bombs and drugs, according to a new study. Fruit flies (Drosophila melanogaster) can detect smells such as those from wine, which the insects are naturally attracted to because it smells like their favorite food, fermenting fruit. Now, new research shows that their keen "noses" could with just as much accuracy identify odors from illicit drugs and explosive substances as well."
