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 ...

The range of materials that concrete contains scatters normal sound waves, making clear imaging difficult to obtain.

3D printing typically involves depositing layers of molten plastic, laser-melting powdered metal, or using UV light to harden gelatinous resin. A new technique takes yet another approach, however, by ...

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.

Concrete structures like roads and bridges require nondestructive testing methods to identify interior defects without destroying their structure. Most methods send sound waves into the material and ...

The idea of growing organs or tissues for medical use still sounds like science fiction — and indeed, it's an incredibly difficult thing to do. 3D-printing technology has shown some promise in the ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Scientists have now used Japan's extensive network of Global ...

Global Navigation Satellite System (GNSS) receivers help with precise location tracking and can detect disturbances in the upper atmosphere (ionosphere) by measuring delays and changes in ...
