Advances in nanotechnology have enabled the creation of ultra-black materials capable of absorbing virtually the entire ...

Yes, you should. I know that feels counterintuitive, but let’s start by pondering this question: Why do people in the United ...

Even after more than a century of research, one of the greatest mysteries about our Sun continues to remain unsolved.

We’re just beginning to decode this faint optical “signature of life” and what it could reveal about health, disease, and the future of medicine.

I love watching the sun rise and set. The color shifts and ombres are unique. I'm always glad that I can see them, and miss them when I can't see them, to the point that at times my digital ...

The following is an extract from our Lost in Space-Time newsletter. Each month, we dive into fascinating ideas from around the universe. You can sign up for Lost in Space-Time here. My first encounter ...

Purple doesn’t actually exist in the visible light spectrum because it’s a nonspectral color created when your brain compensates for the conflicting signals from red and blue wavelengths hitting your ...

On TikTok, you'll find content creators touting red light therapy's benefits for skin care, hair growth, joint pain, sleep, longevity, inflammation — even period cramps. As one TikTok creator who goes ...

Physicists at CU Boulder have demonstrated a new kind of vacuum ultraviolet laser that is 100 to 1,000 times more efficient than existing technologies of its kind. The researchers say the device could ...

Blue light is a high-energy part of visible light from the sun, screens, and light-emitting diode (LED) bulbs. Your cornea and lens don’t block blue light the way they block ultraviolet (UV) rays.

Thanks to modern LED bulbs, light is cheaper than ever to make—except for one particular kind. Three University of Chicago scientists have announced an innovative way to create infrared light, which ...

Dark matter can’t be seen, so simulations like this one show what dark matter might look like if it were visible. The universe is packed with riddles, but few are as stubborn or as fascinating as dark ...
