Research conducted by scientists at MIT has produced a laser-based light and sound system that can send communications to a single, specific target in a number of different settings. The system relies on photo acoustics — sound waves that result from the interaction of light and matter.

This selective audio streaming capability holds promising applications in many fields and is the feature of this week’s Technology Spotlight.
