In day-to-day life, light seems intangible. We walk through it and create and extinguish it with the flip of a switch. But, like matter, light actually carries a little punch—it has momentum. Light ...

People keep searching for “burning laser hacks,” but that’s a fast way to get hurt or start a fire. This video breaks down ...

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 ...

With a powerful laser zap, scientists have blasted toward a milestone for nuclear fusion. A fusion experiment at the world’s biggest laser facility released 1.3 million joules of energy, coming close ...

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 ...

The field of nuclear fusion has seen some exciting advances of late, with scientists demonstrating how fuels can be heated to the temperatures needed for the necessary reactions to take place. All are ...

The universe is filled with magnetic fields. Understanding how magnetic fields are generated and amplified in plasmas is essential to studying how large structures in the universe were formed and how ...

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 ...

An experiment at Lawrence Livermore National Laboratory’s (LLNL’s) National Ignition Facility (NIF) appears to have approached fusion ignition as it recreated the extreme temperatures and pressures at ...

The latest dark matter experiment kicks off this week, as physicists aim to identify the universe's most enigmatic particles. Reading time 2 minutes Long tubes, strong magnets, and bright lasers. Is ...

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 ...
