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 ...

Experts at the BELLA Center used dual laser beams focused onto a sheet of gas to reach a milestone energy in laser-driven electron acceleration. Four members of the larger team gathered with the ...

The properties of dense helium (He) — which happens to be a principal constituent of giant gas planets like Jupiter — at thermodynamic conditions between those of condensed matter and high-temperature ...

Engineers working with the Pentagon’s advanced research arm and a Seattle startup say they are closing in on “infinite flight” for drones by zapping them with high powered lasers from the ground.

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 ...

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 ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. There’s a reason lightning rods haven’t changed much since ...

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 ...

Lightning rods have been used to guide lightning strikes for centuries, but now scientists have demonstrated something a bit more advanced than a humble metal stick. Beaming a high-powered laser into ...
