Over the past few decades, engineers have developed various devices that can create holograms, three-dimensional (3D) or ...

If you think breaking a Nature Valley granola bar makes a mess, try a photon. As fundamental particles, photons can’t really be cleaved into smaller pieces. But if you tried cracking a light particle ...

Researchers at Penn have created a hybrid light-matter particle that could dramatically speed up AI computing while using far less energy. The breakthrough may help replace some electronic computing ...

The speed of light in a vacuum has been known as both a universal constant and a hard speed limit for all matter in the universe ever since Albert Einstein published his special theory of relativity ...

Undulator-generated radiation and safety shielding in an LSW experiment. The combination of standard synchrotron radiation and safety shielding by themselves provides a convenient platform for ...

Our planet is under a constant bombardment of radiation—from space. Well, maybe it’s not as scary as that makes it seem. “Radiation” is a catchall term astronomers use for forms of light—including ...

A new particle has popped into existence at CERN’s Large Hadron Collider, a heavier proton-like particle that contains two charm quarks. Protons and neutrons are examples of a class of particles ...

The Sun unleashes a torrent of charged particles. Some of them slam into the Earth’s atmosphere, triggering breathtaking auroras in the night sky. But for equipment that’s orbiting our planet in outer ...

In July 2012, physicists at the Large Hadron Collider (LHC) in Europe triumphantly announced the discovery of the Higgs boson, the long-sought linchpin of the subatomic world. Interacting with Higgs ...
