WELL, BACK HERE, MIDDLE SCHOOL STUDENTS ARE LEARNING TO BEND LIGHT AND SOUND WAVES. IT’S NOT JUST FOR SUPERHEROES. EIGHTH GRADERS AT BEEDLE MIDDLE SCHOOL EXPLORED THE LUMINARIUM TODAY. THEY DISCOVERED ...

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 ...

In new research that will have implications for the development of computers, scientists have successfully stored light-based information in the form of sound waves. These sound recordings have been ...

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 ...

A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

Bengaluru: Indian Institute of Science (IISc) researchers have developed a non-invasive technique to measure blood glucose levels using polarised light and sound waves, offering hope for people with ...

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 ...
