Researchers recently created an acoustic hologram, or a 3D sound field projected onto a 2D space, which can be used as acoustic tweezers, cages and twisters that manipulate objects as they levitate in ...

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 ...

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 ...

Sounds are caused by vibrations. When an object vibrates, it causes movement in air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. That vibration ...

"Wondering About Sound" is an educational film that explores the nature of sound and how it is created through vibrations. It explains that sounds can be high or low, loud or soft, and are caused by ...

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 ...

It may seem straight out of "Star Trek," but it's real: Scientists have created a sonic "tractor beam" that can pull, push and pirouette objects that levitate in thin air. The sonic tractor beam ...
