Excited by the prospect of future missions to the Jupiter system, Bruce Gibb explores the chemistry of Jupiter’s moons and wonders whether there could be life on Europa.

John Steele and Stephen Wallace discuss recent advances in the chemical and biotechnological synthesis of the prolific platform chemical adipic acid.

Lack of standardization, transparency and interaction creates information gaps in scientific publications. Through strategies such as voluntary information management, standardization of reaction set-ups, and smart screening approaches, this Perspective gives guidelines on how to improve data management in publications reporting chemical reactions, focusing on reproducibility, standardization and evaluation of synthetic transformations.

Nanopore label-free sequencing of DNA and RNA at the single-molecule level offers rapid readout, high accuracy, low cost and portability. This Review surveys technologies underpinning commercial and academic nanopore sequencing, and examines how underlying biochemical advances can fuel future developments in nanopore-based protein sequencing.

Understanding how membrane-bound styrene oxide isomerase (SOI) catalyses the Meinwald rearrangement—a Lewis-acid-catalysed isomerization of an epoxide to a carbonyl compound—can be useful as SOI represents a green alternative to chemical synthesis. Here, the catalytic mechanism of SOI was determined using cryo-EM, EPR spectroscopy, mutagenesis, functional assays and docking experiments.

Calcium difluoride is a source of fluorochemicals, but the reactivity of Ca–F moieties is not well understood. Now a library of molecular Ca–F complexes featuring unique structural motifs has been synthesized, including via fluorochemical defluorination. Studies of mono- and dinuclear systems provided structure–activity relationships for E–F bond formation.

Dimetallocenes are a narrow class of compounds represented by the homobimetallic examples dizincocene and diberyllocene. Now a heterobimetallic dimetallocene featuring lithium and aluminium centres has been synthesized. The Al–Li bond is shown to cleave upon reaction with N-heterocyclic carbenes and heteroallenes.

Chiral sulfur pharmacophores are crucial in drug discovery, but the controlled synthesis of sulfinamides with stereogenic-at-sulfur(IV) centres is a long-standing challenge. Now a method for the catalytic asymmetric synthesis of sulfinamides and sulfinate esters has been developed that features the acyl transfer sulfinylation of diverse nucleophiles, including aromatic amines and alcohols, using chiral 4-arylpyridine N-oxides as catalysts.

Fusicoccane diterpenoids are complex natural products with intricate tricyclic skeletons and intriguing biological activities. Now a chemoenzymatic strategy has been developed for modularly synthesizing a number of compounds from the family. This approach combines de novo skeletal construction and hybrid C–H oxidations, allowing the synthesis of ten different natural products.

The number of known high-oxidation-state transuranic compounds remains limited, and these typically feature high coordination numbers and/or multiply-bonded donor atoms. Now, a tetrahedral, pentavalent neptunium complex supported by four monoanionic ligands has been isolated and characterized. This complex is stable in the solid state and undergoes a proton-coupled electron transfer reaction in solution.

Serotonin is known by many names — in science as 5-hydroxytryptamine (5-HT) or enteramine, and in popular culture as the ‘feel good’ chemical or the ‘happy hormone’. Cameron Movassaghi and Anne Andrews discuss the knowns and unknowns of this well-studied yet elusive neurotransmitter.

Becoming an assistant professor brings with it several challenges, one of which is developing new relationships that can be professionally and personally beneficial. Shira Joudan reflects on getting to know people at a new institution, having different types of relationships, and how they help with happiness and success.

Ciro Romano, Jack I. Mansell, and David J. Procter have explored the versatility and selectivity of samarium diiodide, and its use as a radical relay catalyst.

Thomas Kruse and Søren Østergaard reflect on the development of the GLP-1 analogue, semaglutide, which is reshaping peptide therapeutics in type 2 diabetes, weight management, and beyond.
