Sound is usually treated as the most familiar of physical phenomena, the background noise of daily life rather than a ...

A unique X-ray technique allowed scientists to film soundwaves’ propagation in a diamond crystal. A world first, their results pave the way for ultra-fast imaging of solid materials such as metals, ...

Acoustic frequency filters, which convert electrical signals into miniaturized sound waves, separate the different frequency bands for mobile communications, Wi-Fi, and GPS in smartphones. Physicists ...

Researchers have succeeded in directing floating objects around an aquatic obstacle course using only soundwaves. Their novel, optics-inspired method holds great promise for biomedical applications ...

Helium leaks are hard to detect, since it is odorless, colorless, tasteless, and does not react with other chemical ...

Save your breath: A new way to make bubbles requires only sound waves. Scientists made the bubbles in levitated drops of liquid, held aloft with sound waves. Tweaking the sound waves caused the ...

Researchers in Switzerland have found a way of using sound waves to manipulate objects in disordered environments such as liquids. Instead of trapping the objects as conventional optical and acoustic ...
