Designing efficient redox mediators for solar-to-fuel conversion is a challenge, requiring multi-electron transfer, suitable redox potential, and stable pH buffering. Here, the authors report polyoxometalate-based mediators with defect engineering, enabling reliable solar-to-fuel conversion.

China operates a national surveillance program for acute respiratory infections and sampled over 200,000 patients between 2009–2019. Here, the authors present results from this program and describe patterns by age, pathogen type, presence of pneumonia, and season.

Diarrhoea is a major cause of morbidity and mortality in China. Here, the authors present results from a large sentinel surveillance scheme from 217 hospitals in all 31 provinces in mainland China, including ~150,000 patients with acute diarrhoea and covering years 2009-2018.

Non-pharmaceutical interventions implemented to mitigate COVID-19 transmission are likely to have impacted spread of other infectious diseases. Here, the authors investigate changes in the incidence of 31 notifiable infectious diseases using surveillance data from China.

Conjugated polymeric molecules are promising electrode materials for batteries. Here the authors show a two-dimensional few-layered covalent organic framework that delivers a large reversible capacity of more than 1500 mAh g⁻¹ with the storage mechanism governed by 14-electron redox chemistry.

The dynamic kinetic asymmetric C−O cross-coupling has presented significant challenges and remains unexplored. Here, the authors report the dynamic kinetic asymmetric C−O cross-coupling of oximes and phenols via copper/BOX-catalysed enantioselective O-arylation with diaryliodonium salts.

The discovery of biomarkers remains challenging owing to a lack of methods sensitive enough to identify such rare molecules. Now, by simultaneously exploiting the catalysis and affinity of a DNAzyme, candidate biomarkers with low abundance in cancers can be pulled down for identification and validation.

The dicarbofunctionalisation of unactivated alkenes normally requires the use of exogenous strong coordinated directing groups. Here, the authors report a Ni(II)-catalysed dicarbofunctionalisation of unactivated alkenes with aryl/alkenyl boronic acids and alkyl halides as the coupling partners with a diverse range of native functional groups as the directing group.

Chronic rhinosinusitis with nasal polyps generally has a type 2 inflammatory eosinophilic profile but can have a treatment resistant neutrophilic phenotype. Here the authors characterise nasal polyps using single cell sequencing and spatial transcriptomics and show granzyme K⁺CD8⁺ T cells associated with neutrophilic inflammation which promote release of neutrophilic chemoattractants from fibroblasts.

The adsorptive separation of olefin–paraffin mixtures requires the development of robust adsorbents with high selectivity and adsorption capacity. Here the authors develop a physiosorbent featuring surface sieving carbon skins several nanometers in thickness, with molecular-selective pores centered at 3.6 Å, for separation of C₃H₆ and C₃H₈ with high dynamic selectivity.

Efficient catalysts for seawater electrolysis are crucial for sustainable hydrogen production but struggle with slow kinetics and low durability. Here, the authors report a molybdenum nitride catalyst that in situ generates ammonium groups, enhancing both performance and stability in natural seawater.

Cryptococcus neoformans causes opportunistic infection and potentially lethal immunopathology but therapeutic options are limited. Here the authors implicate myeloid derived suppressor cells during C. neoformans infection and suggest targeting arginase-1 production as a potential therapeutic strategy.

Synaptic pruning is important during development and synaptic plasticity. Here, the authors show that the dopamine D2 receptor (Drd2) in the anterior cingulate cortex regulates synaptic pruning, affecting LTD and behaviour in transgenic rats.

Methods to functionalize inert C–H bonds are a critical focus of synthetic organic chemistry. In this work the authors use computations and experiments to uncover the mechanisms of palladium-catalysed C–H lactonizations in aromatic carboxylic acids, and explain the origin of an observed preference for functionalization of a C(sp3)–H bond over a C(sp2)–H bond in a recent report.

Developing durable catalysts for carbon dioxide reduction to formate at commercial-scale current densities is challenging. This work reports that indium sulfide stabilized through zinc incorporation can produce formate efficiently and quickly at high current densities over long timescales.

The assembly of the Photosystem II proximal antenna CP47 remains a challenging question. Here the authors show that FPB1 and PAM68 act coordinately with Alb3 and the SecY/E translocon to facilitate the co-translational integration of specific regions of CP47 into thylakoids.

Shi et al. show that following adrenergic signalling, PKA phosphorylates AIDA, which in turn interacts with and promotes oxidation of UCP1 to regulate UCP1-dependent adaptive thermogenesis.

The authors report an Initial Upper Palaeolithic archaeological assemblage from China dating to 45,000 years ago that includes blade technology, tanged and hafted projectile points, long-distance obsidian transfer and the use of a perforated graphite disc.

Abnormal placentation is associated with recurrent spontaneous abortion (RSA) risk. Here the authors report that low embryonic villous succinate level associates with risk of RSA in patients, and increasing succinate levels is sufficient to reduce the incidence rate in a mouse model of spontaneous abortion.

‘Candidatus Methanoliparum’ overexpresses genes encoding alkyl-coenzyme M and methyl-coenzyme M reductases—markers of archaeal multicarbon alkane and methane metabolism—and thrives on a variety of long-chain alkanes and n-alkylcyclohexanes, and n-alkylbenzenes with long n-alkyl (C_≥13) moieties.

Immune profiling of the tumour microenvironment of soft-tissue sarcoma identifies a group of patients with high levels of B-cell infiltration and tertiary lymphoid structures that have improved survival and a high response rate to immune checkpoint blockade therapy.

A light-activated chloride pump that occurs naturally in bacteria can be transfected into neurons, thereby permitting inhibition of neural activity on a millisecond timescale. This complements an existing tool for activating neurons through a photoactivatable algal channel.

Maintaining food security by increasing smallholder production is a global sustainability concern. This study uses field trials on potatoes to demonstrate the positive impact of within-species diversification on yield, disease resistance and improved soil health.

Recently an iron catalyst was developed to catalyze an oxa-Diels-Alder reaction, whose mechanism is unclear yet. Here the authors combine DFT and molecular dynamics simulations with experimental studies to elucidate the unusual iron effect on kinetic isotope effect and dynamics in this reaction.

The medial prefrontal cortex (mPFC) is implicated in pain regulation, yet the underlying mechanisms are poorly understood. Here the authors establish a critical role for mPFC in regulating pain sensation and pain-related anxiety, mediated by activation of the cyclin-dependent kinase 5 signalling pathway.
