A unique X-ray technique allowed scientists to film soundwaves’ propagation in a diamond crystal. A world first, their results pave the way for ultra-fast imaging of solid materials such as metals, ...

Scientists at MIT have directly captured signs of “second sound” in a superfluid for the first time. This bizarre phenomenon occurs when heat moves like sound waves through an unusual state of matter.

Researchers have succeeded in directing floating objects around an aquatic obstacle course using only soundwaves. Their novel, optics-inspired method holds great promise for biomedical applications ...
