| Archaeology: Inequality has deep roots in Eurasia A study of 64 archaeological sites across four continents shows that the growth of agricultural and political systems provoked economic disparities, more so in Eurasia than in North America. | Cancer immunotherapy: The dark side of PD-1 receptor inhibition Inhibiting the protein PD-1 can activate T cells that trigger immune responses against tumour cells. But it emerges that, in mice, this immunotherapy exacerbates a cancer that involves the T cells themselves. | Microbiota: A high-pressure situation for bacteria Analyses in mice suggest that dietary salt increases blood pressure partly by affecting some of the microbes that inhabit the gut. The implications of this work for hypertension warrant further study in humans. | Visualization of chemical modifications in the human 80S ribosome structure A high-resolution structure of the human ribosome determined by cryo-electron microscopy visualizes numerous RNA modifications that are concentrated at functional sites with an extended shell, and suggests the possibility of designing more specific ribosome-targeting drugs. | A Jurassic gliding euharamiyidan mammal with an ear of five auditory bones The fossil of a gliding mammal from the Jurassic period sheds light on both the evolution of gliding and the development of the middle ear, as it has a previously unseen five-ossicle auditory system. | Salt-responsive gut commensal modulates TH17 axis and disease High salt intake changed the gut microbiome and increased TH17 cell numbers in mice, and reduced intestinal survival of Lactobacillus species, increased the number of TH17 cells and increased blood pressure in humans. | Solar abundance ratios of the iron-peak elements in the Perseus cluster High-resolution X-ray spectra show near-solar abundances of chromium, manganese and nickel with respect to iron in the Perseus cluster, suggesting that the progenitors of type Ia supernovae could be near- and sub-Chandrasekhar-mass white dwarfs. | Quantitative microbiome profiling links gut community variation to microbial load Quantitive microbiome profiling reveals that total microbial load is an important determinant of enterotypes and may be a key driver of microbiota alterations in patients with Crohn’s disease. | Structural basis of nucleotide sugar transport across the Golgi membrane Crystal structures of the nucleotide sugar transporter Vrg4 are reported in both the substrate-free and the bound states. | Genome sequence of the progenitor of the wheat D genome Aegilops tauschii OPEN A combination of advanced sequencing and mapping techniques is used to produce a reference genome of Aegilops tauschii, progenitor of the wheat D genome, providing a valuable resource for comparative genetic studies. | Greater post-Neolithic wealth disparities in Eurasia than in North America and Mesoamerica Analyses of house-size distributions in the Old and New World showed that wealth disparities increased with the domestication of plants and animals and with increased sociopolitical scale. | PD-1 is a haploinsufficient suppressor of T cell lymphomagenesis Loss of the PD-1 receptor promotes the development of T cell non-Hodgkin lymphomas by modulating oncogenic signalling pathways, and blocking these pathways reduces tumourigenesis. | IL11 is a crucial determinant of cardiovascular fibrosis | A non-canonical Notch complex regulates adherens junctions and vascular barrier function | Erratum: The neuropeptide NMU amplifies ILC2-driven allergic lung inflammation | Corrigendum: RNA m6A methylation regulates the ultraviolet-induced DNA damage response | | Tidal tomography constrains Earth’s deep-mantle buoyancy An estimate of Earth’s deep-mantle buoyancy is derived from GPS-based measurements of body tide deformation and shown to be dominated by dense material possibly related to subducted oceanic plates or primordial rock. Harriet C. P. Lau, Jerry X. Mitrovica, James L. Davis et al. | Regeneration of the entire human epidermis using transgenic stem cells Autologous transgenic epidermal stem cell cultures are used to reconstitute almost the entire epidermis of a patient with severe junctional epidermolysis bullosa. Tobias Hirsch, Tobias Rothoeft, Norbert Teig et al. | A single-cell survey of the small intestinal epithelium Profiling of 53,193 individual epithelial cells from the mouse small intestine identifies previously unknown cell subtypes and corresponding gene markers, providing insight into gut homeostasis and response to pathogens. Adam L. Haber, Moshe Biton, Noga Rogel et al. | Dynamics of P-type ATPase transport revealed by single-molecule FRET Single-molecule fluorescence resonance energy transfer is used to identify the rate-limiting step and new intermediates in the conformational cycle of the Listeria monocytogenes calcium transporter LMCA1. Mateusz Dyla, Daniel S. Terry, Magnus Kjaergaard et al. | Inflammation-induced IgA+ cells dismantle anti-liver cancer immunity IgA+ B cells expressing programmed death ligand 1 (PD-L1) and interleukin 10 accumulate in the inflamed livers of humans and mice with non-alcoholic fatty liver disease where they promote the progression to hepatocellular carcinoma by limiting the local activation of PD-1-expressing CD8+ T cells. Shabnam Shalapour, Xue-Jia Lin, Ingmar N. Bastian et al. | | Haze heats Pluto’s atmosphere yet explains its cold temperature Modelling results find that the temperature of Pluto’s atmosphere is regulated by haze particles rather than gas molecules, suggesting that Pluto should be brighter than previously thought at mid-infrared wavelengths. Xi Zhang, Darrell F. Strobel, Hiroshi Imanaka | Granular materials flow like complex fluids The relaxation dynamics of granular materials is more like that of complex fluids than that of thermal glass-forming systems, owing to the absence of the ‘cage effect’. Binquan Kou, Yixin Cao, Jindong Li et al. | Reductions in global biodiversity loss predicted from conservation spending Empirical two-part models describe the relationship between conservation spending, human development pressures and biodiversity loss and can inform sustainable development strategies by predicting the effects of financing decisions on future biodiversity losses. Anthony Waldron, Daniel C. Miller, Dave Redding et al. | Parallel palaeogenomic transects reveal complex genetic history of early European farmers In European Neolithic populations, the arrival of farmers prompted admixture with local hunter-gatherers over many centuries, resulting in distinct signatures in each region due to a complex series of interactions. Mark Lipson, Anna Szécsényi-Nagy, Swapan Mallick et al. | Ubiquitination and degradation of GBPs by a Shigella effector to suppress host defence A Shigella flexneri type III secretion system effector targets cellular proteins for degradation via the ubiquitin/proteasome pathway, suggesting that such effectors help to overcome defences against bacterial infection. Peng Li, Wei Jiang, Qin Yu et al. | Collective emission of matter-wave jets from driven Bose–Einstein condensates Sufficiently strong modulation of the interaction strength in a Bose–Einstein condensate induces inelastic atom–atom scattering and causes collective emission of matter-wave jets from the condensate. Logan W. Clark, Anita Gaj, Lei Feng et al. | Locomotor speed control circuits in the caudal brainstem In the mouse caudal brainstem, functionally distinct neuronal subpopulations, which are distinguishable by neurotransmitter identity, connectivity and location, regulate locomotion parameters. Paolo Capelli, Chiara Pivetta, Maria Soledad Esposito et al. | BCAT1 restricts αKG levels in AML stem cells leading to IDHmut-like DNA hypermethylation The mechanistic basis for the role of the metabolic enzyme BCAA transaminase 1 (BCAT1) in acute myeloid leukaemias. Simon Raffel, Mattia Falcone, Niclas Kneisel et al. | A ubiquitin-dependent signalling axis specific for ALKBH-mediated DNA dealkylation repair A signalling mechanism in human cells for sensing DNA damage induced by alkylation involves ubiquitin-dependent recruitment of the alkylation repair complex ASCC to the vicinity of the damage and co-localization with transcription and splicing factors. Joshua R. Brickner, Jennifer M. Soll, Patrick M. Lombardi et al. | Structure and assembly of the Ebola virus nucleocapsid Application of cryo-electron tomography and subtomogram averaging to determine the structure of the Ebola virus nucleocapsid within intact viruses and recombinant nucleocapsid-like assemblies.
