All objects emit heat in the form of infrared light. This effect is strongest in dry, clear air, especially on cloudless nights. As a result, objects can become colder than the surrounding air. For ...

Researchers have theorized a new mechanism to generate high-energy "quantum light," which could be used to investigate new properties of matter at the atomic scale. The researchers, from the ...

A team of physicists has just modeled an astonishing quantum phenomenon where ultra-powerful lasers generate light from vacuum. This work could soon be experimentally validated thanks to a new ...
