Tired: a plague of locusts
Wired: a legion of cybernetically-enhanced locusts trained by the US military to sniff bombs
That’s the new goal, according to Stars & Stripes magazine:
Navy-funded researchers have discovered that a locust’s sensitive “horns” can distinguish between the scents of TNT and other explosives — a development that one day could herald the deployment of bomb-sniffing, electronically augmented bug swarms.
The research by a team from Washington University in St. Louis, published this month in the science journal “Biosensors and Biolectronics: X,” is the first proof of concept for a system that aims to tap into the antennae and brainpower of garden-variety bugs to create an advanced bomb-detection sensor.
The work is funded by two Office of Naval Research grants totaling more than $1.1 million, and biomedical engineering professor Barani Raman believes it has the potential to produce a biorobotic sniffer that would be leaps ahead of entirely man-made “electronic noses.”
In the Washington University study, which is available to read online, the locusts were able to distinguish between the smells of common explosive chemicals such as TNT, DNT, RDX, PETN and ammonium nitrate — all in less than a second. Which is, admittedly, pretty impressive.
Insects like locusts also offer benefits over, say, bomb-sniffing dogs, in that they already tend to swarm together, and don’t require a lot of food and care. There’s also less of an ethical concern — no one cares if you attach sensors and cameras to a bug, but even military dogs still inspire a certain protective instinct in their human companions that could discourage such technological enhancements (or the experimentation required to figure out how to use them best).
