“We can use the sound waves to apply just the right amount of pressure in the right places to the stem cells, to trigger the change process,” said Leslie Yeo, co-lead researcher on the study.

The content discusses the fundamentals of acoustics, focusing on sound refraction, the anatomy of the ear, and how sound waves are perceived. It explains how sound travels through the ear, the ...

A team of researchers is proposing a radical new technique for killing cancer cells using low-intensity ultrasound waves. The work is still at an early stage but cell tests have shown sound waves ...

Manipulating and detecting ultrahigh frequency sound waves: 1,000 times higher resolution ultrasound images possible Date: June 11, 2014 Source: DOE/Lawrence Berkeley National Laboratory Summary ...

Researchers have revealed how high-frequency sound waves can be used to build new materials, make smart nanoparticles and even deliver drugs to the lungs for painless, needle-free vaccinations.

The way the cells responded depended on the frequency, intensity and pattern of the sound wave. The response also varied based on the type of cell. The most significant finding of the study was ...

When two ultrasonic beams of slightly different frequencies, such as 40 kHz and 39.5 kHz, overlap, they create a new sound wave at the difference between their frequencies – in this case 0.5 kHz ...
