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 ...

Yushun Zeng squishes cancer cells in a petri dish at work. No, not with his ungainly, macroscopic human fingers. Zeng, an engineering graduate student at the University of Southern California, has ...

A collaboration between researchers from Virginia Tech and Oak Ridge National Laboratory (ORNL) in the US has built a chip-scale device that can trap and control sound waves in a way that mimics the ...

A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant ...

Patterned elastic plate guides ultrasonic waves and traps different frequencies at separate bulk locations, enabling compact ...

For every action, there is an equal and opposite reaction. What goes up, must come down. Physical laws like these govern all of the natural world — except for the tiny internal components of today’s ...

Time crystals, a collection of particles that "tick"—or move back and forth in repeating cycles—were first theorized and then discovered about a decade ago. While scientists have yet to create ...

For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small distances between two crystals in a vacuum. When you purchase through links on our site, we may ...

The top layer represents the location of the sound source and the path of sound propagation (A). The bottom layers represent convergence zones with different sound propagation paths (B-F). Sound waves ...
