Vibrations Reveal State of Bridge Ropes

To guarantee safety of bridges, regular inspections are required. However, visual methods allow the damage to be detected in a rather advanced state only. Other methods such as ultrasound, radiography, or magnet-inductive testing are time-consuming and expensive. And, the bridges have to be closed to traffic.

Army Envisions Smarter Robots In Its Future

Unmanned robots have already proven their worth on the battlefield, neutralizing improvised explosive devices, and more capable ones are coming in the future, according to the commander of U.S. Army Training and Doctrine Command. While robots and unmanned platforms will continue to provide valuable assistance to soldiers on the battlefield, there may even come a day when they can begin replacing soldiers, Gen. Robert W. Cone told reporters at the recent Association of the United States Army's Aviation Symposium. Cone's remarks sparked further discussion at a Jan. 22 media roundtable, co-hosted by the College of William & Mary and U.S. Army Training and Doctrine Command, known as TRADOC, held on the campus of W&M.

Laser Scientists Create Portable Sensor For Nitrous Oxide, Methane

Rice University scientists have created a highly sensitive portable sensor to test the air for the most damaging greenhouse gases. The device, created by Rice engineer and laser pioneer Frank Tittel and his group, uses a thumbnail- sized quantum cascade laser (QCL) as well as tuning forks that cost no more than a dime to detect very small amounts of nitrous oxide and methane.
