At its start, the universe was a superhot melting pot that very briefly served up a particle soup resembling a "perfect," frictionless fluid. Scientists have recreated this "soup," known as ...

Researchers have demonstrated the existence of a tetraneutron, a subatomic structure once thought unlikely to exist. Iowa State University researchers have helped demonstrate the existence of a ...

Powerful supercomputer simulations of high-energy collisions between atomic cores provide new insights about the complex structure of a superhot fluid called the quark-gluon plasma. At its start, the ...
