Metasurfaces are ultrathin optical components engineered with arrays of nanoscale structures that can control light in ways that are difficult for conventional optics. Unlike traditional optical components, which typically ...

It is common for solar panels to be shaded by trees, clouds, birds or buildings. For thin-film solar technologies, however, such shading can cause shaded areas to develop reverse-bias stress (negative voltage), which can ...

Underwater environments are among the harshest operating conditions for electronic devices. Divers and underwater robots depend on sensors to navigate, communicate and handle objects, but conventional sensors are fragile, ...

No wires. No actuators. Shine light on the metal surface, and it rises like a button. KAIST researchers have developed a metal structure that changes shape using light, without any light-absorbing coating. This technology ...

An aircraft powered by a megawatt-class hybrid-electric engine developed in collaboration with NASA and built by GE Aerospace, demonstrated flight of an innovation that can inform new generations of fuel-saving aircraft power ...

A new modeling study finds that weak AI regulation may be worse than no regulation at all when it comes to the safety of AI products and services.

A research team led by Kyunghan Lee, a professor in the Department of Electrical and Computer Engineering at Seoul National University College of Engineering, has developed an artificial intelligence system, "Ouroboros," ...

Large language models (LLMs), the computational algorithms underpinning ChatGPT, Gemini and other artificial intelligence (AI)-powered conversational platforms, are now widely used worldwide. These models can rapidly answer ...

Optical see-through augmented reality (AR) glasses are designed to overlay digital information onto the real world, but improving the realism of virtual objects often comes at a cost. Existing occlusion technologies physically ...

Tech firms are racing to roll out advanced smartphones that use artificial intelligence to do everything from ordering food to composing messages with a simple voice command.

Concrete is the most widely used building material on Earth, and producing it is one of the largest single sources of carbon emissions. One promising way to reduce its environmental footprint is to 3D-print concrete, laying ...

Another powerful new artificial intelligence model from China took the U.S. tech industry by surprise Friday, the latest sign that Chinese startups that publicly release their "open-source" AI technology are making the California ...
