Mechanical engineers have devised a diagnostic platform that uses sound waves to spin an individual drop of water up to 6000 revolutions per minute. These speeds separate tiny biological particles ...

It's the sound of water droplets falling one after another, maybe from a leaky faucet or through a cracked ceiling. It's the kind of sound that can keep you up all night. University of Cambridge ...

This blue-glowing water is being spun around by nothing but sound waves. Reaching speeds up to 6,000 RPM, this centrifuge forms the basis for a new type of inexpensive, point-of-care biomedical test.
