Physicists observe antihelium-4 nucleus, the heaviest antinucleus yet
(PhysOrg.com) -- In 1932, scientists observed the first antimatter particle, a positron (or antielectron). Since then, scientists have observed heavier and heavier states of antimatter: antiprotons and antineutrons ...

From two-trillion-degree heat, researchers create new matter -- and new questions
(PhysOrg.com) -- A worldwide team of researchers have for the first time created a particle that is believed to have been in existence immediately after the creation of the universe - the so-called "Big Bang" ...

The perfect liquid -- now even more perfect
Ultra hot quark-gluon-plasma, generated by heavy-ion collisions in particle accelerators, is supposed to be the "most perfect fluid" in the world. Previous theories imposed a limit on how "liquid" fluids can ...
