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 ...

In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...

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”.
