Sound waves are used in many imaging applications, but they're often underpowered and hard to focus. But focus them into "sound bullets" and all sorts of interesting things happen. A paper published ...

What does the future of construction look like? Autonomous machines buzzing around a building site? Giant 3D printers extruding walls and floors? Looking forward even farther, researchers at the ...

Researchers have taken a novel approach to studying the interaction between certain topological metamaterials and sound wave propagation. The technique, described by IMDEA Materials' Dr. Johan ...

Gentle sound stimulation -- such as the rush of a waterfall -- synchronized to the rhythm of brain waves significantly enhanced deep sleep in older adults and tripled their ability to recall words, ...
