Researchers at the University of Hong Kong demonstrate negative light refraction with the natural magnetic material CrSBr – ...

Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as ...

By combining two fundamentally different microscopy techniques, researchers can now measure the optical properties of a ...

In this video, I use transparent water beads to create an awesome disappearing act right in my classroom. I fill a bowl with the beads, then pour in water until they seem to completely vanish. As I go ...

American Water Works — a supplier of drinking water and wastewater services to more than 14 million people — on Monday said hackers had breached its computer networks and systems, prompting it to ...

Abstract: The global navigation satellite system-interferometry reflectometry (GNSS-IR) has been considered commonly to be reliable for retrieving water level. However, the GNSS signal undergoes ...

A common property of water refraction is that the bottom of a pool appears closer than it actually is. In these two images we can see no difference between refraction being turned on and off. Note ...
