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 ...

Muons are unstable subatomic particles that spontaneously and rapidly transform into other particles via a process known as ...

Physicists have built a tractor beam out of lasers that can both repel and attract objects across distances 100 times farther than previously possible. Michelle Starr is CNET's science editor, and she ...

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

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 ...

The ZEUS laser facility at the University of Michigan has roughly doubled the peak power of any other laser in the U.S. with its first official experiment at 2 petawatts (2 quadrillion watts). At more ...

Scientists at the Paul Scherrer Institute PSI have, for the first time, demonstrated a technique that synchronizes ultrashort ...

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 ...

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 ...
