Toward super-fast motion of vortices in superconductors An international team of scientists from Austria, Germany, and Ukraine has found a new superconducting system in which magnetic flux quanta can move at velocities of 10 to 15 km/s. This opens access to investigations of the rich physics of non-equilibrium collective systems and renders a direct-write Nb-C superconductor as a candidate material for single-photon detectors. The results are published in Nature Communications.

Histone H3-H4 tetramer found to be a copper reductase enzyme A team of researchers at the University of California has found that the histone H3-H4 tetramer is a copper reductase enzyme. In their paper published in the journal Science, the group describes two experiments they carried out that showed that histones are involved in reducing copper inside of cells. Johannes Rudolph and Karolin Luger with the University of Colorado at Boulder have published a Perspective piece in the same journal issue giving an outline of research involving histones and describing the work done by the team in California.

Rare-metal abundance points to a missing companion star for the supernova Cassiopeia A The massive star that exploded to form the supernova known as Cassiopeia A most likely had a companion star that has yet to be spotted, a spectroscopic analysis by RIKEN astrophysicists suggests. This will provide fresh impetus to efforts to locate the companion.
