Powerful Tool Crunches Commutes

Websites for commuters are nothing new, but researchers in Sunnyvale, Calif., have developed an advanced system with a twist: in addition to tracking traffic congestion, the program crunches data from 14,000 sensors, in some cases every 30 seconds, to decipher evolving rush-hour patterns.

How Media's Representation of 'Nanotechnology" Is Shaping Public's Opinion

A professor is analyzing how "nanoscience" and "nanotechnology" are being defined and presented by the media. This information is important, he explains, because the media plays a major role in "framing" issues, such as a new technology's "promise" or "threat," in the public mind.
