The Large Hadron Collider (LHC), a 27 kilometer (17 mile) long particle accelerator straddling the border of Switzerland and France, is nearly set to begin its first particle beam tests. The European Organization for Nuclear Research (CERN) is preparing for its first small tests in early August, leading to a planned full-track test in September - and the first planned particle collisions before the end of the year. The final step before starting is the chilling of the entire collider to -271.25 C (-456.25 F)

It’s thought that there are some fifty-four thousand licensed batches of radioactive materials in the U.S. that could be used in a dirty bomb.

In October, 2005, a radiation sensor at the Port of Colombo, in Sri Lanka, signalled that the contents of an outbound shipping container included radioactive material. The port’s surveillance system, installed with funds from the National Nuclear Security Administration, an agency within the Department of Energy, wasn’t yet in place, so the container was loaded and sent to sea before it could be identified.

Those who came of age during the era of Three Mile Island and Chernobyl are probably too young to remember the happy days when "our friend the atom" promised electricity too cheap to meter and cars that would run forever without a fill-up. With atom-powered subs like the Nautilus cruising under the polar icecap in the mid-1950s, could anyone doubt that atom-powered rocketships, airplanes, and even automobiles would be far behind?
