...SmartCheck machine is designed to scan a passenger’s body for guns and explosives and aims to increase the efficiency of secondary searches, which are conducted only after passengers have passed through the metal detector. The scanner provides those passengers selected for such searches with a less intrusive alternative to the pat-down or strip search. The machine is still in its testing stages, but is scheduled to eventually make its way into JFK and Los Angeles International airports...
...government believes that use of the scanner will greatly improve airline safety. A full body X-ray scan can reveal carefully concealed plastic weapons or liquid explosives that metal detectors miss. A 30-second scan in place of a pat-down or strip search would also greatly expedite travelers’ painfully slow passage through security...

Because X-rays pass through clothing, an ACLU officer, quoted in the New York Times, dubbed the scan a “virtual strip search,” claiming that the additional security of the scan is not worth the loss of passenger privacy...
This past fall, the instructors in Sociology 189, “Law and Social Movements,” used Turnitin.com to scan students’ work as part of a plagiarism-detection pilot program run by Harvard’s Instructional Computing Group (ICG).

So researchers are working on finding protein markers in the blood released by tumor cells that spread outside the colon; experts believe that cancer cells that venture outside the original tumor are equipped with special markers...
