Policing BaghdadA new paper by MIT political sociologist Diane Davis draws surprising parallels between the challenges to establishing order and security in Baghdad in 2006, and those faced almost a century ago in Mexico City, right after the ouster of longtime dictator General Porfirio Diaz in 1910.
Davis' paper, "Policing, Regime Change and Democracy: Reflections From the Case of Mexico," also offers a cautionary tale to policymakers: Establishing........Go to the Media-blog (Added on 7/25/2006 6:33:59 PM)
Accelerating The Speed Of LightPhysicist Costas Soukoulis and his research group at the U.S. Department of Energy's Ames Laboratory on the Iowa State University campus are having the time of their lives making light travel backwards at negative speeds that appear faster than the speed of light. That, folks, is a mind-boggling 186,000 miles per second - the speed at which electromagnetic waves can move in a vacuum.
