Physicists at New York University have built a time crystal powered entirely by sound waves, and lab tests suggest the ...

Sound is usually treated as the most familiar of physical phenomena, the background noise of daily life rather than a frontier of fundamental physics. Yet in laboratories around the world, carefully ...

Mechanical engineers have demonstrated a set of prototypes for manipulating particles and cells in a Petri dish using sound waves. The devices, known in the scientific community as 'acoustic tweezers, ...

The acoustic properties of an ultracold fermion gas have been measured either side of the superfluid transition temperature in an experiment that has been described as “near perfect” and “beautiful”.

Researchers have uncovered a way to control material behavior using sound. In a study ...

On the rise. Signs of convection are seen in the motion of hot gas under the influence of a gravity-like acoustic force in a spherical glass container. The images were recorded 15, 40, and 140 ...

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 ...
