  • The image of a fluorescent object hidden behind an opaque layer can be retrieved non-invasively by exploiting the correlation properties of the speckle pattern produced by illuminating the object through the layer using laser light.

  • Exploiting the 'memory' properties of scattered light allows for single-shot imaging through thin opaque layers, including biological tissue.

  • The discovery of a new correlation between the incident field and the laser speckle created by multiple scattering takes us a step closer to imaging in turbid media.

  • An extension of the concept of a random walk is the Lévy flight, in which the moving entity can occasionally take unusually large steps. Pierre Barthelemy and colleagues show how such behaviour can be engineered into an optical material.

  • Metasurfaces can in principle provide a versatile platform for optical functionalities, but in practice designing and fabricating them to specifications can be difficult. Now, the realization of metasurfaces with engineered disorder allows for versatile optical components that combine the best features of periodic and random systems.

  • The modes of random lasers, by their very nature, are difficult to design and control. Here, Gaio, Saxena et al. demonstrate a laser based on a nanophotonic network, instead of random scatterers, which allows tailoring of the optical properties and the lasing output via the network topology.

  • Seeing—and consequently imaging—through turbid media such as fog is a difficult task, as multiple scattering scrambles the visual information. This Review summarizes techniques that physically or computationally reconstruct the images.
