In this issue, S. Bräse et al. review propellanes. How did they evolve from a chemical curiosity to an area of interest in materials science, natural product synthesis, and medicinal chemistry? In their Minireview, O. S. Wenger et al. summarize work on earth-abundant Group 6 element isocyanide complexes as luminophores and photosensitizers with long-lived excited states. The Highlight deals with the cleavage of carbon–carbon bonds in benzene (J. A. Gladysz et al.). In his Essay, E. Meggers discusses the use of octahedral stereocenters in enzyme inhibition and asymmetric photoredox catalysis, and the life and scientific achievements of 1994 Chemistry Nobel Laureate George Olah are presented in the Obituary by G. K. Surya Prakash.

In the Communications section, L. Jiang et al. describe superamphiphilic silicon wafer surfaces and applications for uniform polymer film fabrication (see picture). J. N. Harvey et al. investigate the dynamics of the reaction of FeO⁺ and H₂ as a model for inorganic oxidation. S. Bhattacharjya et al. designed heme-cage β-sheet miniproteins, and J. Chen et al. present Li-CO₂ batteries with liquid-free electrolytes.
