  • Multiple scattering of light in complex and disordered media scrambles optical information. This Perspective showcases how this often detrimental physical mixing can be exploited to extract and process information for optical imaging and computing.

  • It is not immediately obvious whether photons retain the information they carry when they traverse a disordered or multimodal medium. This Perspective discusses the extent to which the quantum properties of light can be preserved and controlled.

  • This Perspective argues that an approach called extreme value theory is appropriate for understanding the so-called tail risk of epidemic outbreaks, in particular by demonstrating that the distribution of fatalities due to epidemic outbreaks over the past 2500 years is fat-tailed and dominated by extreme events.

  • The identification of superconductivity and strong interactions in twisted bilayer 2D materials prompted many questions about the interplay of these phenomena. This Perspective presents the status of the field and the urgent issues for future study.
