  • The field of high-valent uranium chemistry has been dominated by the linear uranyl moiety [UO2]2+ and its imido analogues. A family of tetrakis(imido)uranate dianions has now been developed that displays four uranium–nitrogen multiple bonds. Their geometry is dictated by cation coordination and steric factors rather than electronic ones.

  • Chemical experiments on californium are stymied by isotope availability and radioactivity considerations, but are advanced here with synthesis and characterization of an organometallic complex.

  • Multi-electron redox chemistry is important in transition-metal-mediated processes, but is rarely observed with uranium due to its propensity to undergo single-electron reactions. Now, uranium can use its electrons, coupled with those stored in redox-active ligands, to perform multi electron reduction of organoazides and form uranium tris(imido) derivatives.

  • Disruption of lignin biosynthesis has been proposed as a way to improve forage and bioenergy crops, but it can result in stunted growth and developmental abnormalities; here, the undesirable features of one such manipulation are shown to depend on the transcriptional co-regulatory complex Mediator.

  • Gene-specific changes in DNA methylation are promising biomarkers, but sensitive quantitative detection of these epigenetic marks remains challenging. Li et al. adapt the so-called BEAMing technology to enable high-throughput digital quantification of gene methylation in clinical samples.
