Radioactive, a new biopic of Marie Curie, weaves together her personal story, her discoveries and the repercussions of her research into radioactivity.

An article in Nature Nanotechnology reports a retinal prosthesis made of semiconducting nanoparticles that can be injected into the eye to replace degenerated photoreceptors and restore vision.

An article in Nature Materials reports the control of the mechanical properties of a 2D magnet by changing its magnetization state, and of its magnetization by mechanical deformation.

An article in Angewandte Chemie International Edition reports water oxidation using a linear conjugated polymer photocatalyst.

Self-healable polymers are materials that recover after physical damage. In this Review, we discuss the physical and chemical approaches to make self-healing polymers, with a focus on similarities with biological systems.

Design of bone-tissue-engineering materials involves consideration of multiple, often conflicting, requirements. This Review discusses these considerations and highlights scalable technologies that can fabricate natural and synthetic biomaterials (polymers, bioceramics, metals and composites) into forms suitable for bone-tissue-engineering applications in human therapies and disease models.

Flat metasurface optics provides an emerging platform for combining semiconductor foundry methods of manufacturing and assembling with nanophotonics to produce high-end and multifunctional optical elements. This Review highlights the design of metasurfaces, recent advances in the field and initial promising applications.

Weyl fermions in solids exhibit unique features such as spin–momentum locking and a diverging Berry curvature corresponding to a magnetic monopole in momentum space. This Review surveys the transport phenomena, magnetic excitations and nonlinear optical effects observed in these systems.
