Independent of baseline BMI, higher BMI₂₅ was associated with much higher levels of blood glucose and diabetes prevalence at baseline. After adjusting for potential confounders e.g., age, smoking, and baseline measured BMI, BMI₂₅ had a strong positive log-linear association with all above-mentioned mortality outcomes, those being obese at young adulthood had a HR of 1.85 (95% CI: 1.75–1.95), 1.85 (1.71–2.00), 1.40 (1.26–1.56) and 2.34 (1.96–2.81), respectively, compared with participants having BMI₂₅ of 18.5–20.0 kg/m². The association with cancer mortality was more pronounced in men than in women, but no such heterogeneity was observed for total, cardiovascular diseases (CVD), and respiratory mortality.

Photocatalysis offers a promising route, while the reliance on sacrificial agents and the limited extraction capacity necessitate the development of new photocatalysts. Here, we report the first conjugated organic polymer (COP), BB-COP-AO, that enables external-sacrificial-agent-free photocatalytic uranium extraction from natural seawater. Rational incorporation of benzothiadiazole and pyridine units optimizes the band structure, enhances intramolecular donor–acceptor interactions, and facilitates charge separation, endowing it with high photocatalytic activity. Pyridine nitrogen atoms benefit dissolved oxygen adsorption and pre-activation to promote ·O₂⁻ generation, boosting the uranium recovery efficiency. Furthermore, the suitable valence band enables photogenerated holes to oxidize H₂O to H₂O₂, thereby eliminating the need for external sacrificial agents. Concurrently, amidoxime functionalities ensure selective uranyl binding. Consequently, BB-COP-AO drives selective conversion of the uranyl ions into highly stable metastudtite via a dual-pathway mechanism coupling dissolved oxygen activation and water oxidation. Benefiting from these synergistic effects, BB-COP-AO exhibits an outstanding uranium extraction capacity of 19.80 mg g⁻¹ in natural seawater within 7 d, along with excellent selectivity and recyclability. This work expands the application scope of COP-based materials and offers a generalizable molecular design strategy for developing multifunctional photocatalysts toward sustainable uranium recovery from seawater.</div></div>","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":"71 7","pages":"Pages 1686-1694"},"PeriodicalIF":21.1,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147371986","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}

Geochronological data reveal non-progressive (multi-phase) surface uplift, initiating in the central LT rather than the southern LT adjacent to the collisional front. To resolve the geodynamic drivers of this uplift pattern, we present an integrated analysis of a 345-km-long N-S deep seismic reflection profile traversing the entire LT. This unified transect reveals a critical structural continuity invisible to isolated studies: the non-reflective crust in the southern LT transitions to a continuous north-dipping crystalline basement wedge that tapers progressively northward from the central to northern LT. Integration of multi-disciplinary data with geodynamic modeling supports a three-phase orogenic evolution, suggesting that while the evolving Neo-Tethyan slab dynamics and subsequent Indian collision provided the external geodynamic drivers, the inherited across-strike crustal strength heterogeneity acted as the internal template. Initially, early-stage subduction induced northward basement tilting and early uplift. Subsequently, slab rollback (<70 Ma) drove juvenile crustal accretion and magmatic softening in the southern LT, causing delayed uplift upon Indian indentation. Finally, Late Oligocene-Miocene passive roof thrust systems modified the relief. These validated processes demonstrate that external tectonic forcing interacted with inherited crustal structures to fundamentally affect the spatial progression of thickening, thereby establishing the STP's non-progressive orogenic framework.</p>","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":21.1,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147758932","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}

However, the intrinsic recession of the solid-liquid interface away from the irradiated surface leads to gradually increasing thermal resistance and decaying charging rate with time. To address this challenge, we demonstrate that anchoring the phase change interface achieves rapid, efficient, and continuous solar thermal charging. This is enabled by dynamically circulating photothermal core-shell composite phase change particles (CPCPs) to continuously renew the irradiated surface. Scalable CPCPs, fabricated via extrusion-spheronization, consist of a MnFe₂O₄ photothermal shell and an MgO/h-BN/NaCl-KCl core integrating broadband photon absorption with high thermal conductivity within a single particle. The MnFe₂O₄ shell delivers a solar-weighted absorptance of 91.1%, facilitated by near-surface photon confinement and internal multiple scattering. Within the core, a percolated MgO skeleton combined with in-plane h-BN phonon transport pathways forms a hierarchical ceramic network. The interfacial phonon-spectrum overlap in this structure reduces Kapitza resistance, elevating the effective thermal conductivity to 6.84 W m^-1 K^-1, while maintaining a high energy storage density of 844.7 kJ kg^-1. By matching the incident solar flux with particle stream mass flow rates, the system attains a charging power of 0.54 kW under 1.08 kW solar input. This yields a solar thermal storage efficiency of 49.7%, a 26-fold improvement over conventional diffusion-limited approaches (1.9%).

Previous studies have primarily focused on the activation energy of ion transport based on classical transition state theory, lacking considerations from the perspective of nuclear quantum effects.

Our first-principles calculations based on instanton rate theory indicate that the quantum rate constants diverge significantly from their classical counterparts at low temperatures. We predict that quantum tunneling becomes dominant over thermal diffusion for concerted hydrogen migration at liquid nitrogen temperature, and emerges even at room temperature when concerted transport is suppressed. We also demonstrate the tuning of migration rates by strain, and the sensitivity of the quantum tunneling rate to the energy barrier geometry. Our findings depict a complete quantum picture of hydrogen transport in lanthanide hydrides and provide a new perspective on ionic conductivity of solid materials.</p>","PeriodicalId":421,"journal":{"name":"Science Bulletin","volume":" ","pages":""},"PeriodicalIF":21.1,"publicationDate":"2026-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147758941","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}

Guided by theoretical predictions, a series of Y₂Ru_2-_xM_xO_7-_δ (M = Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn) materials was synthesized, and Y₂Ru_1.8Zn_0.2O_7-_δ (YRZO) was identified as the optimal candidate. Both theoretical and experimental results demonstrate that Zn doping and cation vacancies synergistically optimize the adsorption energies of OER intermediates and stabilize high-valence Ru sites in YRZO, thereby accelerating reaction kinetics and reducing OER overpotentials. Meanwhile, Zn incorporation enhances the covalency of Ru-O bonds, which not only suppresses Ru dissolution but also delays the formation of surface reconstruction layers, thus significantly improving the long-term durability of the electrocatalyst. In situ characterizations verify that the OER process on YRZO proceeds via the adsorption evolution mechanism (AEM).
