Negative pressure is a rare and challenging-to-detect phenomenon in physics. Using liquid-filled optical fibers and sound waves, researchers have now discovered a new method to measure it. In ...

Optical neural networks may provide the high-speed and large-capacity solution necessary to tackle challenging computing tasks. However, tapping their full potential will require further advances. One ...

For the first time, researchers measured singularities in combined light and sound waves moving faster than the speed of ...

It’s a question I’m sure was keeping you up at night: can you make an object spin with a sound wave? The answer, generally speaking, used to be no. Now, though, mechanical engineers have taken a look ...

Scientists Levitated a Particle Smaller Than a Virus and Made It Fire Like a Laser In A Nutshell Researchers at the University of Rochester and RIT built a new kind of laser that uses sound waves ...

Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely ...

Yushun Zeng squishes cancer cells in a petri dish at work. No, not with his ungainly, macroscopic human fingers. Zeng, an engineering graduate student at the University of Southern California, has ...

The Basilica of St. Mary is now aglow with “Luminiscence,” a sweeping light-and-sound experience that transforms the cathedral into a shifting canvas of stars, waves and sacred imagery — marking the ...

As a physical quantity pressure is encountered in various fields: atmospheric pressure in meteorology, blood pressure in medicine, or even in everyday life with pressure cookers and vacuum-sealed ...
