  • Although acceptor-doped barium zirconate is a promising conductor for electrolysers or fuel cells, our understanding of the relationship between proton motion and conductivity is limited. Our simulations now suggest a generic nanoscale percolation mechanism for high mobility in other oxides.

  • Strain can modify properties, but to prevent cracking is limited to films below a critical thickness. Here, by inserting atomic layers into a ferroelectric superlattice, chemical pressure is generated in thicker films, with enhanced figure of merit for tuneable millimetre-wave dielectrics.

  • In a murine model of acute colitis, hyaluronic acid–bilirubin-based nanomaterials have been shown to modulate immune response and the gut microbiome, as well as restore the epithelial barrier.

  • Photonic crystals with optical bandgaps across the entire visible spectrum are generated by reconfiguring three-dimensional blue phase liquid crystalline lattices into long-lived metastable non-cubic structures using sequences of electric pulses.

  • We are updating our editorial policies to further encourage authors to make their data publicly accessible. Publishing Extended Data figures and source data online will also ensure that data are given a more prominent role.

  • Epithelial layers under compression avoid buckling by active contraction, but only up to a well-defined threshold at 35% strain, beyond which buckling occurs.

  • Mild Lewis and Brønsted acid sites within the confined porous structure of a Nb–Al-containing zeolite work in co-operation to efficiently break down bio-based γ-valerolactone to butenes.

  • A transparent, high-permittivity elastomeric dielectric material shows potential for light-emitting soft robots and stretchable optoelectronics that can self-heal.

  • Lamin mutations responsible for muscular dystrophy are shown to reduce nuclear envelope stability, resulting in mechanically induced nuclear envelope rupture, DNA damage and activation of DNA damage response pathways that lead to muscle cell death. Preventing nuclear envelope damage by reducing cytoskeletal forces on the nucleus improves muscle fibre health and function.
