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 ...

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 ...

Scientists have found a competitor to the lightning rod — one of the most tried and true methods of controlling where lightning strikes. The new method is far more expensive, but it allowed scientists ...

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 ...

MIT researchers have built a nanoscale photonic device shaped like a tiny ski jump that launches laser light directly off a ...

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 ...

Tubular laser beams can create what amount to fiber-optic cables made of thin air, researchers report in a study to appear in Physical Review X. Laser-heated air can efficiently transmit light signals ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...
