Have you noticed you're sleeping a little longer? Maybe you're experiencing a shift in appetite — craving more sweets or pasta. In autumn, our bodies sense the change in light as the dark winter ...

Abstract: Conical refraction (CR) is a phenomenon observed when light is transformed into a hollow slanted cone propagating along an optical axis of a biaxial crystal and emerges as a cylinder of ...

What just happened? A Microsoft-backed research team has set a new benchmark for optical fiber performance, developing a hollow-core cable that posts the lowest optical loss ever recorded in the ...

Sun halos typically occur when high-level clouds are blown over the island from the immediate surroundings under favourable wind conditions, according to the National Environmental Agency. The ...

Refraction is the change in the direction of light due to a change in its speed as it enters a different medium. While the speed of light is constant in a vacuum, it decreases in denser materials, ...

It's a lovely summer weekend morning. We relax in our living room with the sunlight coming gently through the windows. We glance outside and can see the green leaves and watch birds in the yard. We ...

Ive may be long gone from his role at Apple, but the company is believed to be still working toward his vision of a device which would look like a single slab of glass. The company’s first major step ...

When light passes through a material, the spatial arrangement of the material’s atoms can cause the light to undergo reflection, refraction, dispersion, or diffusion. Researchers from Heriot-Watt ...

Scientists have long sought to control light in ways that appear to defy the laws of Nature Credit: Lancaster University Scientists have found a way to achieve negative refraction—where light bends ...
