A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

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 ...

From vibrating strings to plasma waves in space, frequency and wave behavior influence phenomena all around us. Scientists, educators, and citizen volunteers are exploring how wave speed, wavelength, ...

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 ...

Acoustic metamaterials are a fast-evolving family of materials which manipulate sound waves in ever more advanced ways. Now, a team led by Changqing Xu at Nanjing Normal University in China has ...

What if you could listen to music or a podcast without headphones or earbuds and without disturbing anyone around you? Or have a private conversation in public without other people hearing you? Newly ...

Ocean waves have long been seen as having huge potential as a source of renewable energy. Waves produce an estimated 50 trillion to 80 trillion watts of power worldwide – nearly two to three times the ...
