New directions in hypernuclear physics

The experimental study of hypernuclei is coming of age. A Perspective in this issue discusses the new methods, current and upcoming experiments.


    • Peoples’ movements are linked with the spread of epidemics — but not always in simple ways. In the past two years, new datasets and analyses have shed fresh light on how to relate mobility and contagion.

    • Chemically active, flexible sheets convert chemical energy into the flow of the surrounding fluid, which, in turn, transforms the sheet’s shape. This Perspective describes how this feedback produces shape-changing 3D objects, coupled oscillators exhibiting spatiotemporal coordination and the rotation of chemically driven gears.

    • Microwave impedance microscopy, a scanning probe technique that measures local conductivity and permittivity with minimal sample preparation, has become a mature tool with fundamental and practical applications. This Technical Review describes its working principles, applications and future opportunities.

    • Nanoscopic chiroptics studies the spin-dependent asymmetric light–matter interactions at the nanoscale, where the asymmetry can stem from the intrinsic properties of materials, structures or light. This Perspective establishes an overarching framework for nanoscopic chiroptics across the spatial, moment and integrated spatial–momentum dimensions, and discusses applications enabled by this approach.

  • December 2021 closes our third year of publication. To celebrate, we look at the links between our review-type articles, and think about what articles we might publish next.

  • Forty years ago saw the introduction of stochastic resonance — the counter-intuitive idea that noise may help a nonlinear system respond to a weak signal.

  • In 1961, Rolf Landauer noted that erasing one bit of information has a thermodynamics cost. This observation explained Maxwell’s demon paradox and was influential in the early days of quantum computing.

  • Integrated approaches with advanced machine learning techniques are becoming necessary to take full advantage of the advanced experimental capabilities of next-generation synchrotrons. Yijin Liu and colleagues discuss the emergence of synergistic machine-and-data intelligence in synchrotron technology, and how it may accelerate scientific discovery.
