For the first time, physicists have simulated what objects moving near the speed of light would look like — an optical ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

Neuroscientists are zeroing in on how special kinds of brain cells help us see things that aren't actually there.

In a world first, Chinese scientists have successfully carried out satellite laser ranging between Earth and the Moon in broad daylight. This achievement marks a monumental leap in space exploration, ...

Researchers set a record by guiding light in 45-meter-long air wave-guides. It's not at every university that laser pulses powerful enough to burn paper and skin are sent blazing down a hallway. But ...

An innovative experiment flying aboard NASA's Psyche mission just hit its first major milestone by successfully carrying out the most distant demonstration of laser communications. The tech demo could ...

Long tubes, strong magnets, and bright lasers. Is that all it takes to entice the shyest particles in the universe to reveal themselves? Physicists working on the ALPS II experiment certainly hope so, ...

Glow-in-the-dark coughs and sneezes? In the coronavirus era, this is what it takes for scientists to figure out which masks work best at stopping aerosol droplets from spreading after a cough or a ...

Scientists are probing topological insulators with circularly polarized light to reveal their many secrets. These exotic materials have potential for quantum computing and other technologies. They ...

It's not at every university that laser pulses powerful enough to burn paper and skin are sent blazing down a hallway. But that’s what happened in UMD’s Energy Research Facility, an unremarkable ...
