In this issue, W.-J. Xiao et al. review visible-light-induced organic photochemical reactions through energy-transfer pathways. What are the most recent advances in this field? In Minireviews, W. Kong et al. discuss the construction of quaternary stereocenters by palladium-catalyzed cascade reactions, and J. Song et al. summarize antimonene research. In their Essay, K. E. Cordova and O. M. Yaghi advocate building a global culture of science, and share their relevant experience in Vietnam.

In the Communications section, S. Ghosh et al. present hydrogen-bonding-regulated supramolecular nanostructures and their impact on multivalent binding (see picture). W. Tan et al. describe the regulation of protein activity and cellular functions mediated by molecularly evolved nucleic acids. T. T. Perkins et al. quantify the initial unfolding of bacteriorhodopsin and thereby reveal retinal stabilization, and J. S. Figueroa et al. succeeded in the photolytic reductive elimination of white phosphorus from a mononuclear cyclo-P₄ transition metal complex.
