A study demonstrates that graphene-based materials can be used to efficiently convert high-frequency signals into visible light, and that this mechanism is ultrafast and tunable. These outcomes open ...

Researchers have successfully demonstrated a spectrometer that is orders of magnitude smaller than current technologies and can accurately measure wavelengths of light from ultraviolet to the ...

Spring is galaxy season for many amateur astronomers. However, when looking through an eyepiece instead of a camera for astrophotography, you might think of this as the season of pale gray smudges ...

The Sun emits electromagnetic radiation across a broad spectrum, including visible, infrared, microwave, radio, ultraviolet, X-ray, and gamma-ray wavelengths. Visible light, comprising wavelengths ...

Under Chairman Ajit Pai, the Federal Communications Commission’s (FCC) work on light-touch regulation and spectrum allocation has made a big difference in helping advance next-generation technologies.

Arable land is at an all-time premium. Since the last ice age, humans have cleared one-third of the earth’s forests and two-thirds of its wild grasslands, much of it for agriculture. And as the world ...
