HOT STUFF  A collision of two heavy ions produces an extremely hot, dense state of matter called quark-gluon plasma (illustration shown). Computer simulations indicate that swirling patterns could form in this material.

Complex swirls and vortices can appear in the souplike phase of matter that existed just moments after the Big Bang. Computer simulations show that this substance, called the quark-gluon plasma, can contain “the hottest smoke ring in nature,” says Xin-Nian Wang of Lawrence Berkeley National Laboratory, coauthor of a paper published in the Nov. 4 Physical Review Letters.
