Making light 'feel' a magnetic field like an electron would
Unlike electrons, particles of light are uncharged, so they do not respond to magnetic fields. Despite this, researchers have now experimentally made light effectively "feel" a magnetic field within a complicated structure called a photonic crystal, which is made of silicon and glass.

New chip opens door to AI computing at light speed
University of Pennsylvania engineers have developed a new chip that uses light waves, rather than electricity, to perform the complex math essential to training AI. The chip has the potential to radically accelerate the processing speed of computers while also reducing their energy consumption.

Using air to deflect lasers
Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original quality of the beam, reports an interdisciplinary research team in the journal Nature Photonics. The researchers have applied for a patent for their method.

Butterfly-inspired films create vibrant colors while passively cooling objects
On a hot summer day, white clothing feels cooler than other colors due to reflecting—not absorbing—sunlight. Other colors like blue or black, will undergo a heating effect as they absorb light. To circumvent this heating effect in colored cooling films, researchers drew inspiration from nanostructures in butterfly wings.
