ScienceDaily (Nov. 3, 2009) — An international team of physicists at Los Alamos National Laboratory has succeeded in using intense laser light to accelerate protons to energies never before achieved. Using this technique, scientists can now accelerate particles to extremely high velocities that would otherwise only be possible using large accelerator facilities. Physicists around the world are examining laser particle acceleration and laser produced radiation for potential future uses in cancer treatment.

What if virtually every cellular handset on the planet enjoyed accurate location awareness? That’s the question I pondered after meeting with GloPos, a startup that’s about to leave stealth mode whose self-learning software algorithm enables any basic GSM or CDMA cellular phone to provide extremely precise locational data without using GPS—or even Wi-Fi, for that matter. The patent-pending technology offers positioning to within 1 to 40 meters, including indoor and underground locations.

University of California, San Diego (UCSD) structural engineers have announced that a violent simulated reproduction of the Northridge earthquake shook a seven-story structure at the UCSD Jacobs School of Engineering’s Englekirk Structural Engineering Center, and resulted in only minor cosmetic damage to the building. The experiment, along with earlier shakes, was conducted to test a revolutionary new theory that mid-rise concrete apartment, condominium and hotel structures can be built to survive powerful earthquakes using less steel reinforcement than currently required by California building codes.
