By combining ultrasound with a concept called nonlinear acoustics, you can create sound that stays silent until it reaches a ...

What happens when a quantum physicist is frustrated by the limitations of quantum mechanics when trying to study densely ...

The “Helmholtz resonator” concept explains the frequencies of sound produced by clapping the hands together in different configurations.

Metamaterials are materials that possess exotic properties, and the metamaterial assembled at the École Polytechnique ...

“Second sound is the hallmark of superfluidity, but in ultracold gases so far you could only see it in this faint reflection ...

Blood glucose is usually measured using invasive methods involving pricking small needles into the skin. But people suffering ...

Imagine a world where sound becomes visible. In a room full of conversation, we would see soundwaves flowing from person to ...

Blood glucose is usually measured using invasive methods involving pricking small needles into the skin. But people suffering ...

To get around the constraints of quantum physics, researchers have built a new acoustic system to study the way the minuscule atoms of condensed matter talk together. They hope to one day build an ...
