United States engineers have created a better way of detecting bombs and it involves labs.
Using a 3D printer, US engineers have created a fake dog nose which is 18 times better than current devices at sniffing out explosives, contraband and even cancer.
The artificial dog snout can be attached to current commercially produced bomb detectors, increase their sensitivity.
Normally, explosive sampling machines use one of two methods: a passive approach where samples are presented to the detector, or a suction approach, where the detector draws in nearby molecules.
Dogs use a different mechanism. They actively sniff – sucking and expelling air repeatedly, at a rate of approximately five sniffs per second.
