Researchers will report a new laser-based sensor that effectively detects buried objects even while the detector is in motion. This new device offers a significant improvement over existing ...

Tractor beams have hit the big time. A newly constructed device generates a beam of concentrated sound that, for the first time, exerts a continuous, perceptible tug on objects large enough to see.

No smoke, no mirrors, just sound was all scientists needed to levitate objects in midair. NPR reports that researchers at the University of Tokyo have discovered a new levitation technique through ...

Researchers have been pushing the capabilities of materials by carefully designing precise structures that exhibit abnormal properties that can control acoustic or optical waves. However, these ...

WASHINGTON -- Detecting landmines can be a challenging and slow process. Detecting them from a moving vehicle would make the process more speedy, but at the expense of accuracy. At the Optical Society ...
