Physicist Paul Sorensen describes discoveries made at the Relativistic Heavy Ion Collider (RHIC), a particle accelerator at the U.S. Department of Energy's Brookhaven National Laboratory. At RHIC, scientists from around the world study what the universe may have looked like in the first microseconds after its birth, helping us to understand more about why the physical world works the way it does -- from the smallest particles to the largest stars.
Dmitri "Dima" Kharzeev has been awarded the Humboldt Research Award, a prestigious international award issued by the Alexander von Humboldt Foundation in Bonn, Germany, for scientific excellence in his field.
When heavy ions collide at high energies at Brookhaven's Relativistic Heavy Ion Collider, the components of the nuclei melt to form a hot soup of their constituent particles. A new model that describes the patterns of particles flowing out from this "quark-gluon plasma" suggests that the resistance to flow is close to the ideal limit used to define a "perfect" fluid.
