Theorists calculated how the key ingredients of a phenomenon called the chiral magnetic effect should evolve over time in an expanding quark-gluon plasma. The theorists used the holographic principle to model the magnetic fields and other relevant characteristics needed for the effect. The results will help scientists interpret collision data and plan new searches for the chiral magnetic effect and the underlying quantum anomaly.

Future commercial fusion power plants will need to achieve temperatures of 100 million degrees C, which requires careful control of the plasma. Researchers have now achieved these temperatures on a compact spherical tokamak called ST40. The results are a step toward fusion pilot plants and the development of more compact, and potentially more economical, fusion power sources.

Physicists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC) have published the first observation of directed flow of hypernuclei -- short-lived, rare nuclei that contain at least one hyperon. The results may give insight into hyperon-nucleon interactions and the structure of neutron stars.
