coondoggie writes "A researcher working for the National Institute of Standards and Technology has demonstrated an optical technique for identifying tiny amounts of a broad range of molecules in the breath, potentially enabling a fast, low-cost screening tool for disease. In this approach, NIST researchers analyze human breath with "frequency combs," which are generated by a laser specially designed to produce a series of very short, equally spaced pulses of light. Each pulse may be only a few millionth billionths of a second long. The laser generates light as a series of very narrow frequency peaks equally spaced, like the teeth of a comb, across a broad spectrum. The tool sounds like yet another example of a Star Trek-like device making its reality debut. On Star Trek, Tricorders had multiple functions but the medical version used by Bones McCoy could scan a body and help diagnose and heal injured or sick patients. http://www.networkworld.com/community/node/25185"

It's clever, but is it art?
