Scientists Create Clock So Powerful It Can Measure Spacetime and Gravity

New Technology Uses Lasers to Transmit Audible Messages to Specific People

Researchers have demonstrated that a laser can transmit an audible message to a person without any type of receiver equipment. The ability to send highly targeted audio signals over the air could be used to communicate across noisy rooms or warn individuals of a dangerous situation such as an active shooter. In The Optical Society (OSA) journal Optics Letters, researchers from ...
