  • When a system is driven across a second-order phase transition, defects can form because it cannot respond quickly enough to the new conditions. The Kibble–Zurek mechanism explains this physics, and has now been invoked for Ising-type domains.

  • The Magnus effect refers to rotating objects developing a lift force when travelling through a fluid. It normally vanishes at microscopic length scales but now a very large Magnus effect is demonstrated for spinning colloids in viscoelastic fluids.

  • Local thermodynamic measurements of a twisted transition metal dichalcogenide heterostructure reveal competition between unconventional charge order and Hofstadter states. This results from the presence of both flat and dispersive electronic bands, whose energetic ordering can be experimentally tuned.

  • A trilayer copper oxide superconductor, which exhibits the highest superconducting critical temperature as a function of the number of copper–oxygen planes, is shown to have unusual doped hole distribution and interaction between the planes.

  • Wrinkling of cell nuclei is associated with disease. During development, the nucleus behaves like a sheet of paper and the wrinkling amplitude can be manipulated without changing its pattern.

  • Hubbard excitons are elusive quasiparticles that are predicted to form in strongly correlated insulators. Detecting their internal structure and dynamics clarifies the involvement of spin fluctuations in their binding and recombination processes.

  • Claims of a room-temperature, ambient-pressure superconductor recently kicked up a storm on social media. As the dust settles, we take stock of what this experience can teach us.

  • Originally invented to improve cornering techniques in race driving, speed traps contribute to road safety. Robert Wynands introduces us to tools of traffic metrology.
