It is unclear whether the superconducting pairing in moiré graphene is driven primarily by electronic interactions. Now, by tuning the electrostatic environment, the authors show that these interactions may play a crucial role in both mediating the pairing and screening it.

Physical networks can learn to accomplish tasks on the fly by adjusting their internal parameters. Now it is shown that such physical learning can be achieved in metamaterials that can learn to change shape.

Synchrotron experiments show that the anomalous hyper-diffusive atomic motion in metallic glasses corresponds to a regime of medium-length-scale order, resulting from internal stresses developed throughout the glass transition.

Controlling the rotational motion of nanoscale objects by trapping and cooling is a prerequisite for exploring quantum rotational phenomena. Now, two orthogonal librational modes of a levitated nanorotor are cooled into their quantum ground state.

Theoretical descriptions of surface wetting so far cover only equilibrium situations and therefore do not describe active matter. Now a formalism for the description of the wetting of a surface by self-propelled particles is presented.

Odd-parity spin-triplet superconductivity remains difficult to establish experimentally. Now, several distinct magnetic-field-tuned superconducting states—including a possible topological helical phase—have been identified in YbRh₂Si₂.

Fifty years ago, the theoretical concept behind free-electron lasers was proposed. Since then, these light sources, operating from millimetre to X-ray wavelengths, have been indispensable for many areas of science.

Early radiography methods, such as conventional X-ray scans, gave physicians only limited information about what happens inside the body. Rachel Toth tells us how this case was cracked with computed tomography.

The information contained in the nomination process for the Nobel Prize highlights the ever-changing meaning of scientific recognition.

Quantum technologies could be transformative for healthcare. Alex Jones, Ian Gilmore and Peter Knight discuss the role of metrology in the adoption of these technologies.
