High-tech contact lenses correct color blindness

Researchers have incorporated ultra-thin optical devices known as metasurfaces into off-the-shelf contact lenses to correct deuteranomaly, a form of red-green color blindness. The new customizable contact lens could offer ...

New 3-D display takes the eye fatigue out of virtual reality

There is a great deal of excitement around virtual reality (VR) headsets that display a computer-simulated world and augmented reality (AR) glasses that overlay computer-generated elements with the real world. Although AR ...

A better way to measure acceleration

You're going at the speed limit down a two-lane road when a car barrels out of a driveway on your right. You slam on the brakes, and within a fraction of a second of the impact an airbag inflates, saving you from serious ...

Reactive optical matter: Light-induced motion

Newton's third law dictates that forces between interacting particles are equal and opposite for closed systems. In a non-equilibrium environment, the third law can be defied, giving rise to "nonreciprocal" forces. Theoretically, ...

Laser-powered 'needle' promises pain-free injections

From annual flu shots to childhood immunizations, needle injections are among the least popular staples of medical care. Though various techniques have been developed in hopes of taking the "ouch" out of injections, hypodermic ...

Scientists discover how to distinguish beams of entangled photons

A team from the Faculty of Physics, MSU, has developed a method for creating two beams of entangled photons to measure the delay between them. In the future the results of the study may be used in high-precision measurements, ...
