NASA created a haunting audio clip of sound waves rippling out of a supermassive black hole, located 250 million light-years away. The black hole is at the center of the Perseus cluster of galaxies, ...
Using a series of standing ultrasound waves, it is possible to suspend small particles at the sound pressure nodes. The acoustic axis of the ultrasound beam is parallel to gravity, which also ...
The system uses sound waves to move particles and other tiny things, like cells, without a scientist having to physically manipulate them. The idea of using sound waves in such a way is not ...
Developing antiviral therapeutics and vaccines requires close study of the viruses that cause disease. But how can these small germs be isolated from complex biological samples like saliva?
