A new device for creating individual "phonons" — vibrational quanta — could give rise to the acoustic equivalent of lasers.

Doppler ultrasound blends physics and medical imaging to reveal the movement of blood through vessels and the heart. From diagnosing clots to assessing heart valve function, it’s a non-invasive tool ...

Doppler ultrasound works by measuring frequency shifts in sound waves as they bounce off moving red blood cells, translating them into waveforms that reflect blood flow patterns. In obstetrics, this ...

Acoustic metamaterials are a fast-evolving family of materials which manipulate sound waves in ever more advanced ways. Now, a team led by Changqing Xu at Nanjing Normal University in China has ...

Researchers at McGill University have developed a novel device that generates sound-like particles known as phonons at ...

The celestial objects were unknown until a little more than 60 years ago, but even the name is now part of our lexicon.

High-frequency ultrasound platform for preclinical imaging, supporting real-time visualization of small animal anatomy and ...

R. W. WOOD and one of us (Loomis) have described (Phil. Mag., 4, 417; September 1927) certain physical and biological effects observed with high frequency sound waves of great intensity. To obtain ...

MIT demonstrates that seeds sense the sound of rainfall—and sprout faster even while still beneath the surface.

In physics, a mechanical kink marks the point of transition between different internal states of a material. Researchers have now succeeded in creating a model in which they were able to move the kink ...

In a makeshift demonstration kitchen in Concord, California, cooking oil splatters in and around a frying pan, which catches ...

NASA wants to make supersonic travel quieter. On Thursday the agency released new footage of its X-59 jet, a ...
