In the new device, an array of 256 speakers, each about 1 centimeter wide, faces another, identical speaker array across a distance of 23 centimeters. The speakers emit sound waves at frequencies too ...

An elegantly simple experiment with floating particles self-assembling in response to sound waves has provided a new framework for studying how seemingly lifelike behaviors emerge in response to ...

Acoustofluidics elegantly merges acoustics with fluid mechanics, enabling precise manipulation of fluids and particles on both micro and nanoscales. This interdisciplinary field plays a crucial role ...

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.

Conventional wisdom in physics dictates that sound waves are massless fluctuations in pressure that travel through materials like air, water, and eardrums — and can’t travel through empty space.

Developing antiviral therapeutics and vaccines requires close study of the viruses that cause disease. But how can these small germs be isolated from complex biological samples like saliva?
