In this issue, S. R. White et al. review biomimetic self-healing. How did scientists, inspired by nature, create synthetic materials that can regenerate their mechanical integrity and specific functions after damage? In a Minireview, I. J. S. Fairlamb discusses redox-active NO_x ligands in palladium-mediated reactions. The Highlights deal with microbes living in human bodies (H. B. Bode) and iterative synthesis (J. Hartwig and A. Kirschning).

In the Communications section, C. J. Yang et al. demonstrate how to translate molecular recognition into a pressure signal to enable portable biomedical analysis (see picture). L. S. Cederbaum et al. describe a barrierless single-electron-induced cis-trans isomerization. P. Chen et al. succeeded in nickel-catalyzed cyclopropanation reactions with NMe₄OTf and n-BuLi, and C. A. Seipp et al. report on aqueous sulfate separation by crystallization of sulfate–water clusters.
