PolygamousRanchKid writes with this quote from CNN about the future of airport security: "Earlier this year, the International Air Transport Association demonstrated its vision for the 'checkpoint of the future' — a series of neon-lit tunnels, each equipped with an array of eye-scanners, x-ray machines, and metal and liquid detectors. ... 'Known Travelers,' (those who have completed background checks with government authorities) for instance, will cruise through the light blue security corridor with little more than an ID check, while those guided through the yellow 'Enhanced' corridor will be subjected to an array of iris scans and sensitive contraband detectors. ... Feeling guilty? Got something to hide? A team of UK-based researchers claim to have developed a thermal lie-detection camera that can automatically spot a burning conscience. ... Professor Byeong-chun Lee, who established his reputation in 2005 as the driving force behind the world's first ever dog clone, has bought a new breed of super-sniffers to South Korea's Incheon Airport. They may look like an ordinary pack of golden Labrador Retrievers, but these dogs are all genetically identical to 'Chase,' a dog whose legendary snout kept him top of Incheon's drug-detection rankings right up until his retirement in 2007."
