For the first time, a quantum radiation reaction in strong electromagnetic fields has been demonstrated experimentally by ...

Cracking a 15 year physics mystery, researchers measured the precise size of a proton. In A Nutshell A team in Germany used an unprecedentedly precise laser measurement of hydrogen to pin down the ...

The vacuum ultraviolet region is the area of the electromagnetic spectrum lying between X-rays and visible light. It is ...

Physicists at the UK’s Central Laser Facility have recorded the first observation of quantum radiation reaction, detecting how electrons lose energy in ways that classical physics cannot explain when ...

Dozens of times over the last decade NASA scientists have launched laser beams at a reflector the size of a paperback novel about 240,000 miles (385,000 kilometers) away from Earth. They announced ...

At any given moment, trillions of particles called neutrinos are streaming through our bodies and every material in our surroundings, without noticeable effect. Smaller than electrons and lighter than ...

Some days really are longer than others. And now scientists know by precisely how much. Using a laser gyroscope, scientists have measured variations in Earth’s rotation rate smaller than a millionth ...

Physicists in China have demonstrated that a structure called an optical metasurface can individually trap up to 78,400 ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. A laser named after the most powerful god in ancient Greece is ...

researchers at Colorado University Boulder have used doughnut-shaped beams of light to take detailed images of objects too tiny to view with traditional microscopes. The researchers say that the new ...
