This study identifies a human antibody fragment that recognizes i-motifs and shows that these DNA structures are present in the nuclei of human cells.

The archetypal hydride donor for unsaturated organics, LiAlH₄, has also been used in catalytic reductions. Indeed, LiAlH₄ has now been shown to be a precatalyst for imine hydrogenation under mild conditions.

The union of theory in chemical ecology with modern methods in chemistry has enhanced our understanding of phytochemical variation among and within plants. This Review outlines these theoretical frameworks and approaches for hypothesis testing, with a focus on chemically mediated plant–insect interactions.

Single-atom catalysts are heterogeneous materials featuring active metals sites atomically dispersed on a surface. This Review describes methods by which we prepare and characterize these materials, as well as how we can tune their catalytic performance in a variety of important reactions.

Ultrafast X-ray spectroscopies enable the investigation of fast chemical dynamics with time resolutions reaching the order of attoseconds. Processes such as spin crossover, structural deformations in excited states and dissociation reactions can now be studied through the use of short X-ray pulses produced by high-harmonic, free-electron-laser and synchrotron sources.
