The first experiments to study the quark-gluon plasma at the LHC reveal that even at the hottest temperatures ever produced at a particle accelerator, this extreme state of matter remains the best example of an ideal liquid.

A recent theory of high-energy bottom quark jet quenching in nuclear collisions accentuates the novelty of heavy quark jet dynamics in strongly coupled quark-gluon plasmas discovered at the Relativistic Heavy Ion Collider.
The insights of a provocative connection between general relativity and quantum field theory, called the AdS/CFT correspondence, have been extended to rotating black holes that can occur astrophysically.
Quantum field theoretic extensions of Einstein’s theory of gravity tend to suffer from incurable infinities, but a theory called supergravity may actually avoid them—against expectations held for almost 30 years.
