Physicists track sequential 'melting' of upsilons

Scientists using the Relativistic Heavy Ion Collider (RHIC) to study some of the hottest matter ever created in a laboratory have published their first data showing how three distinct variations of particles called upsilons ...

NASA's Psyche fires up its sci-fi-worthy thrusters

NASA's Psyche spacecraft passed its six-month checkup with a clean bill of health, and there's no holding back now. Navigators are firing its futuristic-looking electric thrusters, which emit a blue glow, nearly nonstop as ...

For Canadian researcher, it's a microscopic Christmas

There was Tiny Tim, and then the Little Drummer Boy—but they had nothing on the microscopic gingerbread house believed to be the smallest in the world and unveiled Wednesday by a Canadian researcher.

Research sheds light on how silver ions kill bacteria

The antimicrobial properties of silver have been known for centuries. While it is still a mystery as to exactly how silver kills bacteria, University of Arkansas researchers have taken a step toward better understanding the ...

Collisions of light produce matter/antimatter from pure energy

Scientists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy Office of Science user facility for nuclear physics research at DOE's Brookhaven National Laboratory—have ...

'Strange' glimpse into neutron stars and symmetry violation

New results from precision particle detectors at the Relativistic Heavy Ion Collider (RHIC) offer a fresh glimpse of the particle interactions that take place in the cores of neutron stars and give nuclear physicists a new ...
