Researchers have broken a centuries-old law of physics, putting us on a path towards making better energy-harvesting devices, such as solar cells. Atoms at temperatures beyond absolute zero may be a ...

A thermal metasurface is made of a single layer of nanostructured silicon (gray) on top of glass (blue) and a metal mirror (gold). The nanostructured surface is specifically tailored so that it ...

Radiation is energy that moves from one place to another in a form that can be described as waves or particles. We are exposed to radiation in our everyday life. Some of the most familiar sources of ...

The NWS notes that tule fog, a special kind of radiation fog, occurs each winter in the Central Valley of California. The Weather Network, a Canadian weather information service, says tule fog is ...
