Has the deconfinement phase transition been seen?
New results from the NA49 experiment at CERN suggest that the onset of the transition to deconfined quarks and gluons has been observed at the lower end of the SPS energy region.
Deuteron-gold collisions clarify 'jet quenching' results
New measurements at RHIC provide further insight into heavy-ion collisions at high energies.
ALICE prepares for still higher energies
Collisions of lead ions at the LHC will take heavy-ion physics into a new high-energy regime.
On the trail of dark energy
One of the most remarkable discoveries of recent years is that the universe appears to be dominated by some form of "dark energy", as Eric Linder explains.
mSUGRA celebrates its 20th year
The SUGRA20 conference recently celebrated the 20th anniversary of the invention of minimal supergravity grand unification, or mSUGRA, as Paul Frampton and Pran Nath describe.
The tale of the Hagedorn temperature
Johann Rafelski and Torleif Ericson recall Rolf Hagedorn's discovery of a limiting temperature - in effect a melting point for hadrons - and its influence on the physics of strong interactions.
Frontier techniques for particle physics and beyond
