Evolving roughly 27 different times in the long history of fish, bioluminescence -- the biological production of light -- is one of the flashier survival tools used for luring prey, communication, and ...

By squeezing terahertz light beyond its usual limits, researchers have exposed hidden quantum "jiggles" inside a ...

Here’s what you’ll learn when you read this story: In quantum field theory, a vacuum is never completely empty. Electromagnetic particles like electrons and positrons are always passing through in ...

The Mamyshev oscillator (MO) is a type of fiber laser capable of producing high-energy laser pulses at a tunable repetition rate. It is a mode-locked laser which uses light travelling within a ...

Scientists pushed photons across the universe to test the speed of light—and found Einstein’s cosmic speed limit still holds ...

Physicists from Trinity College Dublin believe new insights into the behavior of light may offer a new means of solving one of science's oldest challenges—how to turn heat into useful energy. Their ...
