PASADENA, Calif.—Taking inspiration from a popular executive toy ("Newton's cradle"), researchers at the California Institute of Technology (Caltech) have built a device—called a nonlinear acoustic ...

Researchers at the California Institute of Technology (Caltech) have built a device that produces highly focused, high-amplitude acoustic signals dubbed "sound bullets." Called a nonlinear acoustic ...

A new machine inspired by a common office toy could one day allow doctors to zap cancerous tumors using "sound bullets," scientists say. Dubbed an acoustic lens, the device could also be used to ...

Acoustic lenses are employed in a variety of applications, from biomedical imaging and surgery to defense systems and damage detection in materials. Focused acoustic signals, for example, enable ...

Sound waves are commonly used in applications ranging from ultrasound imaging to hyperthermia therapy, in which high temperatures are induced, for example, in tumors to destroy them. In 2010, ...

A machine that fires powerful "sound bullets" made from concentrated noise could be used to treat cancer, say scientists. Two researchers have devised a prototype "acoustic lens" that focuses sound ...
