New audio tech uses ultrasound to create isolated pockets of sound, enabling private listening without headphones.

Scientists have been unable to confirm the existence of time reflection due to the amount of energy required to create a ...

In the future, this method could also be used in technical applications with electromagnetic waves. Water, light and sound waves usually propagate in the same way forward as in a backward direction.

For centuries, the reflections of light or sound have been theorized. Scientists have always thought of another variable: ...

Blood glucose is usually measured using invasive methods involving pricking small needles into the skin. But people suffering ...

Today, modern technology called imaging uses things like sound waves, many types of light, and even streams of electrons to make images we can’t see with our eyes alone. These tools make the images we ...

Blood glucose is usually measured using invasive methods involving pricking small needles into the skin. But people suffering ...

Kyoto Prize winners came to San Diego for this year’s symposium. Kyoto Laureate John Pendry talked about the theory of ...

This special interference — or coherence — between photons results in a highly focused and uniform beam of light. Sound waves can be similarly coherent, and scientists have even created sound ...

Until now, this so-called cloaking had only been studied for waves such as light or sound. They report their results in Nature Communications. Making objects invisible is no longer a purely ...
