Bomb detector works better with fake dog nose on the end

Researchers 3D print model snout and fit it to machine programmed for dog-like quick sniffs instead of long breaths, discovering it is 16 times more sensitive

Struck by the legendary sniffing skills of man's best friend, scientists in the United States fitted a dog-inspired plastic nose to an explosives detector and reported that it worked 16 times better.

With the prosthetic nose, and programmed to take quick "sniffs" of the air rather a single long breath, the machine was 16 times much more sensitive in detecting molecules in the air, the team reported in the journal Scientific Reports.
