A strange form of matter called a time crystal has fascinated physicists for about a decade. These systems move in repeating ...

Mathematicians and engineers have teamed up to show how ultrasound waves can organize carbon particles in water into a sort of pattern that never repeats. The results, they say, could result in ...

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 ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Nagoya University scientists and their collaborators have ...

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 ...

Mathematicians and engineers at the University of Utah have teamed up to show how ultrasound waves can organize carbon particles in water into a sort of pattern that never repeats. The results, they ...
