A spacecraft that never runs out of fuel sounds like science fiction, but a team at Texas A&M University has taken a small, literal step toward that goal. In experiments conducted at the university’s ...

Scientists have advanced metasurface technology by developing a new design that simultaneously projects holographic images and creates special diffraction patterns with ten-fold rotation symmetry of ...

Unlike ordinary rainbows, fogbows only appear in humid conditions. Here’s the science behind them—and where you have the best chance of seeing one. A rare fog bow arches over North West England's ...

Vacuum ultraviolet (VUV, 100–200 nm) light sources are indispensable for advanced spectroscopy, quantum research, and semiconductor lithography. Although second harmonic generation (SHG) using ...

Could another prominent Front Range peak get a new name? Not yet. The Colorado Geographic Naming Advisory Board on Jan. 27 declined to advance a proposal to change the name of Longs Peak in Rocky ...

Focusing water waves is a potential technology improving the power generation of wave energy converters. Two semi-ellipsoidal reflectors, including long-axis opening and short-axis opening, were ...

AlGaN-based deep ultraviolet light-emitting diodes (DUV-LEDs), as a novel solid-state ultraviolet light source, compared with the traditional ones, have competitive advantages over traditional UV ...

The formation of a rainbow requires the observer to be between the sun and falling rain, with the rain in front and the sun behind. Sunlight passes from behind the observer, refracts as it enters each ...

Oct 9 (Reuters) - Reflection AI, a startup backed by Nvidia, said on Thursday it has raised $2 billion in a new funding round that values the company at $8 billion, as investor interest in artificial ...

Experiential learning, very simply put, is a process of learning by intentional and thoughtful doing, which can allow for a deeper understanding of yourself and your work. This is in stark contrast to ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...
