New fibre optic record allows 50,000,000 movies to be streamed at once

A Southwest Research Institute-led study found that protons and heavy ions react differently to solar magnetic reconnection events, revealing a more complex magnetic engine powering the solar wind. Magnetic reconnection converts magnetic energy into explosive kinetic energy, powering solar events and causing space weather that impacts Earth. Magnetic reconnection energizes protons and heavy ions, sending them shooting out from the sun at high speeds.

In a first for the field, materials scientists from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have interfaced two materials to artificially generate a highly conductive ferroelectric charged domain wall. Led by associate professor of materials science and engineering Arend van der Zande and graduate student Shahriar Muhammad Nahid (now a postdoc at Stanford) and published in Advanced Materials, their approach highlights the versatility of charged domain w

Anna spends most of her workday typing on her laptop. After a few hours, she starts rubbing her wrists as her pain sets in. A glance at her desk reveals the painkillers that she uses to ease her discomfort. And for John, his neck pain sets in every time he listens to the news about a potential economic crisis and his stress levels start to rise.

Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field rotates. The other comes from the shape of the wavefront itself, which can twist like a corkscrew as it travels. This second form, known as orbital angular momentum, has attracted wide interest because it allows light to encode information, interact with matter in new ways, and probe physical and biological systems. Despite this promise, producing well-defined twisted light
