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, ...

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 ...

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.
