A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant ...

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. While ...

We can hear sounds because our ears turn sound vibrations from the air, into signals that are sent to our brain. We can’t hear all levels of sounds. Sound waves with very high frequencies are called ...

This experiment demonstrates how water affects sound waves and pitch. You'll discover how different water levels create different musical notes and learn about the relationship between mass, vibration ...

Researchers have used sound waves to turn stem cells into bone cells, in a tissue engineering advance that could one day help patients regrow bone lost to cancer or degenerative disease. Researchers ...
