Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves. Water, ...

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 ...

A new tool that assesses the level of danger posed by tsunamis in real-time has been made operational on a global scale. The early warning system, Global Real-time Early Assessment of Tsunamis (GREAT) ...

Physically, sound is just pressure moving through a medium. If you harness that pressure correctly, you can actually push things around using nothing but sound. That's exactly what researchers at ...

An international team of scientists has developed a new analysis of how sound waves behave, revealing surprising effects that ...

Optical neural networks may provide the high-speed and large-capacity solution necessary to tackle challenging computing tasks. However, tapping their full potential will require further advances. One ...

Gayle Anderson learns about Sonic Fire Tech, a startup company founded by former NASA engineers, that uses a patented technology to extinguish wildfires using sound waves. Company officials claim the ...
