However, achieving superior performance under high-temperature and high-electric-field remains a huge challenge due to the increased leakage current and limited breakdown strength. Herein, a high-entropy driven multiscale optimization strategy is proposed for lead-free multilayer ceramic capacitors. This approach integrates multiple elements into both A- and B-sites at the atomic scale, engineers polymorphic domain coexistence at the phase scale, and introduces a uniform SiO2 coating layer on grain surfaces to form a core–shell structure while refining grain size at the grain scale. Furthermore, a SiO2 barrier layer is constructed between the electrodes and ceramics at the device scale. Remarkably, high-entropy BaTiO3-based Multilayer ceramic capacitors achieve an ultra-high energy density of 19.8 J·cm−3 and a high efficiency of 89.3% at 1421 kV·cm−1, along with an outstanding high-temperature energy storage performance. The high-entropy driven multiscale optimization strategy offers a universal approach to enhancing the overall energy storage performance of advanced dielectric capacitors.","PeriodicalId":19066,"journal":{"name":"Nature Communications","volume":"34 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2026-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149242010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Somitogenesis, the rhythmic segmentation of vertebrate embryos, is controlled by signalling gradients and oscillations in the presomitic mesoderm (PSM), but the underlying protein dynamics remain largely unknown. Here, we combine microfluidic synchronisation of mouse embryo tails with quantitative proteomics and transcriptomics to resolve spatiotemporal protein dynamics during somitogenesis. We identify proteins with dynamic expression during somitogenesis and reveal an antiparallel, dynamic R-Spondin/LGR signalling pattern that explains how Wnt oscillation amplitude increases despite declining Wnt ligand levels in the anterior PSM. Dynamic ligand expression is validated in mouse gastruloids, and perturbation of ligand dynamics reduces oscillation amplitude and impairs somite formation. Together, our findings identify R-Spondin as a dynamic amplifier of Wnt signalling oscillations and provide a mechanistic framework for understanding how protein dynamics regulate mammalian tissue patterning.","PeriodicalId":19066,"journal":{"name":"Nature Communications","volume":"96 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2026-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149241784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We validate EndoRare across four rare pathologies: calcifying fibrous tumor, juvenile polyposis syndrome, familial adenomatous polyposis, and Peutz-Jeghers syndrome. Experts judge the synthetic images clinically plausible, and data augmentation significantly improves downstream AI classifiers, increasing true positive rates at low false-positive rates.

Carbon fiber felts offer potential, yet weak inter-fiber bonding and poor conductivity limit the performance. We report a roll‑to‑roll laser processing strategy that uses a liquid precursor to form laser‑induced graphene at fiber‑fiber interfaces, creating conductive pathways and mechanical interconnections. This approach increases tensile strength from 4.1 to 32.2 MPa and electrical conductivity from 1224.0 to 15151.5 S/m. The resulting films demonstrate efficient electrothermal de‑icing and, after copper deposition, lightning strike protection with a damage area of 9657 mm² and depth of 0.4 mm, comparable to aluminum mesh but with 15% lower weight.

Here, a general strategy is presented for visualizing magnetic permeability as a spatially distributed, frequency-dependent field, instead of a uniform bulk parameter. Our framework reveals that high-frequency magnetic loss arises from coherent spin-wave propagation and interference, leading to spatially selective energy absorption and localized regions of negative imaginary permeability. Tailoring geometric connectivity to suppress spin-wave propagation enables the selective enhancement of localized resonances. Such resonance enables deterministic control over high-frequency response through structural design. The principle is further examined in nanoscale iron spheres. Their surface morphology plays a decisive role in reorganizing the internal resonance domains. This structural reconfiguration, in turn, reshapes the broadband magnetic permeability spectra. To navigate the high-dimensional space of surface defect configurations, machine learning models are integrated with micromagnetic simulations, allowing rapid prediction of magnetic performance across microwave bands. Computational modeling provides an ideal platform to complement experimental exploration. The physic-data framework reveals geometry-to-spectra design rules, validated on iron nanoparticles. This framework uniquely bridges the microscopic spin dynamics with electromagnetic response, enabling tunable high-frequency materials for communication and sensing.","PeriodicalId":19066,"journal":{"name":"Nature Communications","volume":"14 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2026-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149241787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

NYNRIN (NYN domain and retroviral integrase containing) is highly expressed in LSC-like cells and is associated with poor prognosis in patients with acute myeloid leukemia (AML). Genetic targeting of NYNRIN impairs LSC-like cell maintenance and in vivo leukemogenic capacity in MLL-AF9- and HOXA9/MEIS1-driven AML models, and compromises the in vivo pathogenicity of patient-derived LSC-like cells. Mechanistically, NYNRIN sustains thioredoxin (Trx) activity by functioning as an RNA-binding protein that directly binds and degrades TXNIP mRNA via its NYN domain. Loss of NYNRIN stabilizes TXNIP mRNA, leading to TXNIP accumulation, which disrupts Trx-mediated redox buffering, induces ROS overproduction and mitochondrial dysfunction, and triggers LSC apoptosis. Notably, NYNRIN inhibition potentiates venetoclax efficacy by compromising Trx-mediated ROS clearance, lowering the apoptotic threshold of LSCs. Collectively, our findings reveal a critical NYNRIN-TXNIP-Trx axis that safeguards LSCs by enabling efficient ROS clearance.","PeriodicalId":19066,"journal":{"name":"Nature Communications","volume":"34 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2026-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149242021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we show a multi-proxy, high-resolution dust record from the western equatorial Indian Ocean spanning the last 500,000 years, which enables evaluation of the influence of orbital-scale hydrological variations on hominin populations in Arabia. The dust evidence reinforces the view that hominin presence in Arabia was driven by enhanced monsoon precipitation during so-called Green Arabia periods. These results, coupled with hunter-gatherer demographic data, point to marked hominin population expansions during prolonged wetter periods. Hominin occupation, however, was not linked exclusively to traditional humid periods. Brief phases of high-intensity rainfall within some glacial periods, manifested by transient high dust contents associated with enhanced terrestrial moisture availability and increased supply of wind-erodible particles, also favoured hominin expansions.","PeriodicalId":19066,"journal":{"name":"Nature Communications","volume":"79 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2026-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149242011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the context of neural network-based quantum Monte Carlo, our method leverages the expressiveness of deep neural networks to capture electron correlation while enforcing exact spin adaptation via group representation theory. This framework provides a principled route to embed physical priors into otherwise black-box neural network wavefunctions, yielding a compact representation of correlated systems with neural network orbitals. To demonstrate its effectiveness, we study the spin ladder of iron-sulfur clusters, a long-standing challenge for many-body methods due to their dense spectrum of nearly degenerate spin states. Our results reveal accurate resolution of low-lying spin states and spin gaps in [Fe2S2] and [Fe4S4] clusters, offering insights into their electronic structures.

We show that more than 60% of mountain ranges are exposed to elevated human pressure and that intensification of human pressure between 2000 and 2020 is associated with the loss of 71.69 Mha of natural mountain habitat. Protected areas provide incomplete buffering from human pressure, while substantial representation gaps remain for mountain vertebrates: 4234 species have less than 10% of their mountain-specific area of habitat represented within protected areas, including 1165 threatened species. We further identify mountain ranges where high biodiversity importance coincides with limited protection and elevated future exposure to land-use change, with priority rankings remaining broadly consistent across socioeconomic scenarios.

We find that RKEC1 forms a compact structure upon ligand binding that lacks any Watson-Crick duplex regions or G-quadruplex core, in stark contrast to nearly all predicted and observed DNA aptamer folds. The atomic details explain dopamine specificity amongst structurally similar compounds, and the determined DNA fold was used to guide biosensor design.
