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 ...

Futuristic control of structure in some materials is being made possible by a physics loophole.

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 ...

An exhaustive search involving thousands of experiments has revealed that a material’s ability to absorb and dissipate energy when impacted is determined principally by the behaviour of sound waves 1.

DURHAM, N.C. - Mechanical engineers at Duke University have demonstrated a set of prototypes for manipulating particles and cells in a Petri dish using sound waves. The devices, known in the ...

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”.

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 ...
