Using the Super Proton Synchrotron, the team created beams of electron-positron pairs and passed them through a meter-long region of plasma. This setup served as a scaled laboratory version of a ...

Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Researchers at Princeton and North Carolina State University have developed a technique that substantially improves the ...

Modern LED technology promised safer roads. Instead, it's creating a blinding menace that regulators refuse to address.

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

Explore how a basic LED can be used as a tiny solar cell, generating measurable voltage under sunlight. This hands-on electronics project demonstrates the photoelectric effect using a multimeter to ...

A thought experiment that was at the heart of an argument between famed physicists Albert Einstein and Niels Bohr in 1927 has finally been made real. Its findings elucidate one of the core mysteries ...

Physicists have achieved record-breaking sensitivity in detecting the faintest traces of light dark matter using an innovative superconducting detector cooled near absolute zero. Their early results ...

TL;DR: This experiment may not revolutionize telecommunications, but it highlights how accessible these concepts have become outside traditional research labs. Using nothing more than an iPad, a solar ...
