Gamma-ray spectroscopy of the superheavy nucleus ${}^{256}$Rutherfordium reveals details of its nonspherical shape and internal structure—the heaviest element for which such information has been obtained.

Colliding matter waves from a Bose-Einstein condensate violate a relation called the Cauchy-Schwarz inequality, proving that such interactions must be considered quantum mechanically.

A new model for DNA-covered nanoparticles predicts their stable crystal structures and may one day help in finding the optimal building blocks for self-assembling materials.

A new resonant emission component from solitons that had been ignored has now been identified and studied.

Majorana’s geometrical representation of quantum spin as points on a sphere offers an intuitive approach to understanding quantum systems with multiple components.

New experiments on an organic ferroelectric verify that its electric polarization is driven primarily by an electron shift, rather than the ion shift that characterizes most other ferroelectrics.

Symmetry considerations point to a universal mechanism responsible for superconductivity in the iron pnictides and iron chalcogenides.

Two groups use different approaches to realize artificial magnetic fields for atoms trapped in a one-dimensional optical lattice.
