Light can behave in very unexpected ways when you squeeze it into small spaces. In a new paper in the journal Science, Mark Brongersma, a professor of materials science and engineering at Stanford ...

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 ...

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 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 ...

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 ...

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 ...
