In this issue, S. Sánchez et al. review chemically powered micro- and nanomotors. What where the major advances in the first ten years of catalytic nanomotors research until now? In a Minireview, U. Meierhenrich et al. discuss molecular chirality in meteorites and interstellar ice, for example on board ESA’s Rosetta mission. In her Editorial, Roberta Sessoli looks at the opportunities available for Italian chemical research.

In the Communications section, H. Liu et al. describe extracellular electron transfer from living microbes and its regulation by surface wettability (see picture). E. L. Chaikof et al. present targeted antithrombotic protein micelles, and K. T. Holman et al. squeezed xenon atoms into cryptophane-111 at up to 300 °C in the solid state. L. J. Murray et al. succeeded in dinitrogen activation upon reduction of a triiron(II) complex. J. Jin and D. W. C. MacMillan show how ethers can be directly α-arylated through a combination of photoredox C–H functionalization and the Minisci reaction.
