...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...

A full body X-ray scan can reveal carefully concealed plastic weapons or liquid explosives that metal detectors miss.

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).

In something resembling a crossover between a Woodstock reunion and an academic conference, several hundred of them - interspersed by the rare business suit - gathered at a church in downtown Prague to celebrate an act of courage they jointly undertook 30 years ago. In 1977, a decade after Soviet tanks had crushed the last flowering of free expression on their city's streets, these men and women signed Charter 77, a human-rights declaration demanding freedoms suppressed by the totalitarian communist regime...
