Ultra high-frequency sound transmits energy through flesh and other materials that block light or heat used in conventional 3D printing. Stephen Shankland worked at CNET from 1998 to 2024 and wrote ...

Researchers at Concordia University have devised a way to solidify liquid into plastic, creating a 3D-printing option that could be used to implement medical implants directly inside a patient's body.

Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency ...

It was an idea born out of curiosity in the physics lab, but now a new type of 'laser' for generating ultra-high frequency sound waves instead of light has taken a major step towards becoming a unique ...
