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”.

A new University of Mississippi study shows that some sound waves don't just move forward—they also move slightly to the side. Understanding this movement could help researchers develop more precise ...

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.

Development for the tire industry has focused on minimizing friction between car and road. The key to high-speed concepts such as Hyperloop, is the elimination of friction in transportation. Which is ...

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 ...

Save your breath: A new way to make bubbles requires only sound waves. Scientists made the bubbles in levitated drops of liquid, held aloft with sound waves. Tweaking the sound waves caused the ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

The interference of sound waves is not just of academic interest. For instance, it is the operating principle of noise-cancelling headphones. These create their own sound vibrations, which are tuned ...
