In this issue, K. Domen et al. review visible-light-responsive photoanodes for highly active, stable water oxidation. What are the recent advances and remaining issues? In Minireviews, J. Adamcik and R. Mezzenga summarize amyloid polymorphism in the protein-folding and aggregation energy landscape; X. Chen at al. discuss stimuli-responsive NO release for synergistic cancer therapy. In his Editorial, P. R. Schreiner writes on chemistry and scientific truth in post-factual times.

In the Communications section, Y.-F. Song et al. report the aggregation of giant cerium–bismuth tungstate clusters into a 3D porous framework with high proton conductivity (see picture). H. Zhang et al. developed highly elastic organic crystals for flexible optical waveguides, and B. M. Stoltz et al. succeeded in the enantioselective synthesis of vicinal all-carbon quaternery centers via iridium-catalyzed allylic alkylation.
