First time accepted submitter titan1070 writes "French scientist Dr. Spitzer and his colleagues have been working on a device that can sense faint traces of TNT and other explosives being smuggled into airports and other transportation methods. the hope for this device is that it will surpass the best bomb finder in the business, the sniffer dog. From the article: ' While researchers like Dr. Spitzer are making progress — and there are some vapor detectors on the market — when it comes to sensitivity and selectivity, dogs still reign supreme. “Dogs are awesome,” said Aimee Rose, a product sales director at the sensor manufacturer Flir Systems, which markets a line of explosives detectors called Fido. “They have by far the most developed ability to detect concealed threats,” she said. But dogs get distracted, cannot work around the clock and require expensive training and handling, Dr. Rose said, so there is a need for instruments.'"
