Kemi Oloyede reflects on the importance of having LGBTQ+ STEM events, and their role in combatting inertia in the scientific community.

Governments worldwide are committing more funding for scientific research in the face of the ongoing pandemic and climate crises. However, the funding process must be restructured to remove the barriers arising from conscious and unconscious biases experienced by minoritized groups, including women, and particularly women of colour.

The time between accepting a position as an assistant professor and taking the role is exciting and unique. But how much work is required before you even start? Shira Joudan ponders which tasks are necessary and how many times one should interrupt a very well-deserved break.

Matthew Horwitz, creator of the Synthesis Workshop video podcast, talks to Nature Chemistry about using podcasting as a driver of professional-level education in the chemistry community.

Crystals of hexachlorobenzene have now been shown to support the autonomous motion of water and particulate matter over their surface. Parallel microchannels present at the surface of the crystal gradually widen by sublimation, propelling droplets of condensed ambient water that can also transport microscopic amounts of material such as silver microparticles.

Stereogenic sp³-hybridized carbon centres are the principal building blocks of chiral organic molecules. Usually, these centres are configurationally fixed. Now, low-energy pericyclic rearrangements have been used to create rigid cage molecules with fluxional sp³-stereochemistry, influencing chiral information transfer. The sp³-carbon stereochemistry of the cages is inverted through strain-assisted Cope rearrangements.

The molybdenum nitrogenase catalytic cofactor is composed of seven high-spin Fe sites making it difficult to study spectroscopically. Now it has been shown that ⁵⁷Fe can be incorporated into a single site and that such site-selectively labelled samples provide insights into the cofactor’s electronic structure and the mechanism of biological nitrogen fixation.

The controlled functionalization of multihydrosilanes is challenging. Now, using a hydrogen-atom-transfer photocatalyst based on neutral eosin Y, a method for the diverse functionalization of hydrosilanes has been developed, enabling the stepwise on-demand decoration of silicon atoms. This approach is distinguished by its atom-, step-, redox- and catalyst-economy, metal-free nature, its versatility (>150 examples), modularity, selectivity and scalability.

The alkaloids crocagins are derived from a ribosomal peptide through a series of enzymatic post-translational modifications. A combination of biochemistry and structural biology techniques has now been used to elucidate this biosynthetic pathway, propose a mechanism for the formation of the tetracyclic core structure and enable genome mining for related natural products.

Aromatic polynitrogen units can display both high stability and high energy content. A hexazine anion has now been identified in a complex compound, K₉N₅₆, which is formed at high pressures and temperatures under laser-heating in a diamond anvil cell. The [N₆]⁴⁻ ring is planar and proposed to be aromatic.

Rahul Dev Mukhopadhyay and Kimoon Kim consider how cucurbiturils — pumpkin-shaped macrocycles — went from curiosities to compelling cavitands for a host of applications.

Winter brings a spike in mortality rates, but rather than simply having more parties to divert our attention, Bruce Gibb suggests that perhaps we should be looking to the misunderstood mushroom to give us a boost.

Methane hydrate clogs pipelines, is difficult to extract profitably, and exists in quantities sufficient to screw up Earth’s climate. Brett Thornton and Christian Stranne consider this confounding cage compound.

Amilra Prasanna (AP) de Silva talks to Nature Chemistry about his path in chemistry, from photochemistry to sodium sensors to logic gates, through connections between people and between two places that share more than it may seem, Sri Lanka and Northern Ireland.
