A study of the thermoelectric properties of the doped insulator, strontium titanate, shows that it superconducts with the lowest charge density ever observed.

Adding impurities to a topological superfluid—a predicted state of matter believed to host Majorana particles—may be the best way to prove it exists.

Photoemission experiments put new constraints on the pairing mechanism in iron-based superconductors.

Ionization experiments with benzene and similar organic molecules show evidence for short-lived electronic couplings, which resemble the Cooper pairs that carry current in superconductors.

The combination of the Josephson effect and topological order provides a testing ground for the emergence of Majorana fermions in solid-state systems.

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