Honey bee workers take on different tasks as they age. The authors study the individuals' social networks and show that interaction patterns predict task allocation and developmental trajectories.
Subduction is the primary driver of plate tectonics, yet we still do not fully understand how subduction zones initiate or the budgets of life-supporting elements recycled via subduction. At Nature Communications, we advocate for more transdisciplinary initiatives and collaborative projects, which are essential if we are to continue to bring new dynamics to subduction research.

High-yield, wafer-scale fabrication of ultralow-loss, dispersion-engineered silicon nitride photonic circuits
For widespread technological application of nonlinear photonic integrated circuits, ultralow optical losses and high fabrication throughput are required. Here, the authors present a CMOS fabrication technique that realizes integrate photonic microresonators on waver-level with mean quality factors exceeding 30 million and 1 dB/m optical losses.
Gallium nitride catalyzed the direct hydrogenation of carbon dioxide to dimethyl ether as primary product
The conversion of CO2 to valuable chemicals is still challenged by catalyst developments. Herein, the authors found that GaN is an efficient catalyst for selective CO2 hydrogenation to dimethyl ether as the primary product, in contrast to the traditional methanol-intermediate route over hybrid catalysts.
Efficient stimulus-responsive phosphorescence organic materials are attractive, but are extremely rare because of unclear design principles and intrinsically spin-forbidden intersystem crossing. Here, the authors present a facile strategy to achieve ultraviolet irradiation-responsive ultralong room-temperature phosphorescence in several simple amorphous polymer materials.
Compared to electromagnetic waves, the wavelength of spin waves is significantly shorter at gigahertz frequencies, enabling the miniaturisation of wave-based devices. Here, the authors present a magnonic Fabry-Pérot resonator allowing for nanoscale and reconfigurable manipulation of spin waves.
De novo design of self-assembling protein nanostructures and materials is of significant interest, however design of complex, multi-component assemblies is challenging. Here, the authors present a stepwise hierarchical approach to build such assemblies using helical repeat and helical bundle proteins as building blocks, and provide an in-depth structural characterization of the resulting assemblies.

Ocean warming and changing circulation as a result of climate change are driving down oxygen levels and threatening ecosystems. Here the author shows that though immediate cessation of anthropogenic CO2 emissions would halt upper ocean oxygen loss, it would continue in the deep ocean for 100 s of years.
Many trajectories for reaching climate change mitigation targets exaggerate the long-term need for CO2 removal (CDR) because they assume an exponentially increasing carbon price. Here the authors analyse alternative carbon price pathways that halt warming while limiting CDR, and may be easier to implement.
This study investigates the relation between El Nino and landslide impacts. The authors show how El Nino and La Nina can cause swings in exposure of population to landslides that are as large as those due to rainy-season/dry-season variability in key locations, particularly South America.
Wetland methane emissions contribute to global warming, and are oversimplified in climate models. Here the authors use eddy covariance measurements from 48 global sites to demonstrate seasonal hysteresis in methane-temperature relationships and suggest the importance of microbial processes.

The structure of human tumor suppressor p53 in complex with the antiapoptotic protein BCL-xL reveals the basis of the p53–BCL-xL interaction and provides insight into the mechanisms of p53-mediated mitochondrial apoptosis.
Photosystem II subunit S (PsbS) senses thylakoid lumen acidification when plants are exposed to excess light. Here the authors use NMR and IR spectroscopy to show that low pH causes repositioning of an amphipathic helix and folding of a loop involving critical pH sensing glutamate residues in PsbS.
Deletion of CTCF sites in the SHH locus alters enhancer–promoter interactions and leads to acheiropodia
Acheiropodia is associated with homozygous deletions in the LMBR1 gene around ZRS, an enhancer regulating SHH during limb development, but how these deletions lead to this phenotype is unknown. Here the authors use whole-genome sequencing, ChIP-seq, 4C-seq and DNA FISH to show that alterations in CTCF motifs are responsible via altered enhancer–promoter interactions.
Classical MHC expression by DP thymocytes impairs the selection of non-classical MHC restricted innate-like T cells
Conventional T cell subsets are selected in the thymus by peptide bearing MHC expressed by cortical epithelial cells, in contrast cortical thymocytes express non-peptide bearing MHC molecules including CD1d and MR1 and select iNKT and MAIT cell populations respectively. Here, the authors generate a novel inducible MHC class-I trasnactivator murine system and suggest the absence of peptide-MHC on thymocytes is involved in the selection of non-peptide specific lymphocytes.
Functional RNA secondary structure is important for the pre-mRNA processing including splicing, cleavage and polyadenylation, and RNA editing. Here the authors present a catalog of conserved long-range RNA structures in the human transcriptome by defining pairs of conserved complementary regions (PCCR) in pre-aligned evolutionarily conserved regions.

Enhanced influenza A H1N1 T cell epitope recognition and cross-reactivity to protein-O-mannosyltransferase 1 in Pandemrix-associated narcolepsy type 1
Narcolepsy type 1 (NT1) is a severe sleep disorder with strong association to the HLA type DQB1*0602 and increased incidence among children vaccinated with the Influenza A vaccine Pandemrix. Here the authors show that these children develop T and B cell autoimmunity against protein-O-mannosyltransferase 1 via cross-reactivity.
Defective viral genomes as therapeutic interfering particles against flavivirus infection in mammalian and mosquito hosts
Defective viral genomes (DVGs) can interfere with virus replication and provide a potential approach to control infection. Here, Rezelj et al. use a combined experimental evolution and computational approach to identify DVG sequences that optimally interfere with Zika virus infection and show antiviral activity in mice and mosquitoes.
The mechanisms by which platelets release sphingosine-1-phosphate (S1P) is not well characterized. Here the authors show that Mfsd2b is required for S1P release from both resting and activated platelets and that deletion of Mfsd2b impairs thrombotic functions of platelets.
Mortality outcomes with hydroxychloroquine and chloroquine in COVID-19 from an international collaborative meta-analysis of randomized trials
Hydroxychloroquine and chloroquine have been investigated as a potential treatment for Covid-19 in several clinical trials. Here the authors report a meta-analysis of published and unpublished trials, and show that treatment with hydroxychloroquine for patients with Covid-19 was associated with increased mortality, and there was no benefit from chloroquine.
Primary and secondary clarithromycin resistance in Helicobacter pylori and mathematical modeling of the role of macrolides
Clarithromycin is a macrolide antibiotic widely used for eradication of Helicobacter pylori infection. Here, Kocsmár et al. study clarithromycin resistance and previous macrolide consumption in 4,744 H. pylori-infected patients, shedding light into the sources of primary resistant cases and the role played by prior consumption of macrolides for non-eradication purposes.

Adverse climatic conditions are commonly reported to shape asylum migration, but their effect relative to other drivers is unknown. Here the authors compare climatic, economic, and political factors as predictors of future asylum flows to the EU and find that war and repression are the most important factors.
Efficiency stagnation in global steel production urges joint supply- and demand-side mitigation efforts
The effectiveness of large historical efforts for decarbonizing steel production is unclear. Here, the authors show that such efficiency gains were offset by a booming steel demand increase. This has led to a stagnating decarbonization progress over past decades, which jeopardizes realization of future climate targets.
The value assessment of job skills is critical for companies to select and retain the right talent and for individuals to develop them. Here the authors show that a data-driven method based on an enhanced neural network can assign meaningful value to job skills in a quantitative way and outperforms benchmark models for job salary prediction.
Recent technological, social, and educational changes are profoundly impacting our work, but what makes labour markets resilient to those labour shocks? Here, the authors show that labour markets resemble ecological systems whose resilience depends critically on the network of skill similarities between different jobs.
Precise knowledge of chemical composition and atomic structure of functional nanosized systems, such as metal clusters stabilized by an organic molecular layer, allows for detailed computational work to investigate structure-property relations. Here, we discuss selected recent examples of computational work that has advanced understanding of how these clusters work in catalysis, how they interact with biological systems, and how they can make self-assembled, macroscopic materials. A growing challenge is to develop effective new simulation methods that take into account the cluster-environment interactions. These new hybrid methods are likely to contain components from electronic structure theory combined with machine learning algorithms for accelerated evaluations of atom-atom interactions.
Equitable partnerships among the international volcano science community are important now more than ever, to cope with financial disparities and ultimately allow for worldwide volcano monitoring oriented to hazard mitigation.

Replication inside macrophages is crucial for systemic dissemination of Salmonella in hosts. In a Nature Communications article, Jiang et al. show that Salmonella stimulates glycolysis and represses serine synthesis in macrophages, leading to accumulation of host glycolytic intermediates that the bacteria use as carbon source and as cues for its replication.
Liver cancer typically arises after years of inflammatory insults to hepatocytes. These cells can change their ploidy state during health and disease. Whilst polyploidy may offer some protection, new research shows it may also promote the formation of liver tumours.
