RHIC experiment results of forming Quark-Gluon Plasma and a possible bubble was news few months ago. I cannot find any follow up news after that. Does anybody know anything new in this front? I am especially interested to hear about the bubble formed.
Edit: The following are some links about this story.

Did a bubble actually formed? What have they found about the bubble? I want more scientific details than one would expect from a newspaper article.
