Dual Nd isotopic archives in fossil teeth reveal bottom-current control of rare-earth element enrichment in deep-sea sediments

The global emergence of deep-sea sediments enriched in rare-earth elements and yttrium (REY) after the Late Eocene cooling coincides spatiotemporally with Antarctic bottom water (AABW) expansion, yet the underlying mechanism remains unresolved. Here, we present in situ elemental...

Deep learning detection of submesoscale eddies from MODIS SST in the South China Sea

This dataset provides daily records of submesoscale eddies in the South China Sea from 2015 to 2024, identified from MODIS Aqua and Terra sea surface temperature (SST) imagery. Distributed as daily TXT files, each record includes eddy polarity, center coordinates (longitude and l...

Asymmetric bloom lengthening drives high-latitude ocean chlorophyll accumulation imbalance

Terrestrial ecosystems maintain a stable time-allocation budget between growth and senescence, but whether this applies to the ocean remains unclear. Using fused satellite LiDAR and ocean-color data (2007–2022), we show that marine phenology is variable and asymmetric. In high la...

Contrasting climatic controls on bimodal growth of Pinus elliottii plantations between northern and southern subtropical zones

Subtropical plantation forests play a crucial role in the global carbon cycle, yet intensifying global warming may exert profound impact on tree growth and forest carbon uptake. Pinus elliottii Engelm. is a widely planted and representative plantation species in subtropical regio...

Reversible Fe exsolution enables a single-layer Sr2Fe1.5Mo0.5O6−δ ceramic interconnect for plasma-sprayed segmented-in-series solid oxide fuel cells

Double-perovskite Sr 2 Fe 1.5 Mo 0.5 O 6−δ (SFM) is promising for solid oxide fuel cell (SOFC) electrodes due to good redox stability and high conductivity, yet its performance suffers from phase degradation under strong reduction. Herein, SFM coatings were prepared via atmospher...

High-resolution late Quaternary Indo-Pacific Warm Pool benthic δ18O stratigraphy for evaluating the precession timing of the marine Asian monsoons

The timing of Quaternary precession-scale (23 kyr) monsoon variations across the Asia-Australia and the Indo-Pacific regions remains highly debated. The Asian monsoon phase differences of approximately 5 ka reported between a suite of marine sedimentary and speleothem proxy recor...

Haima Cold Seeps: Direct Evidence for the Occurrence of Gas Hydrates—A Case Study from the Qiongdongnan Sea Area, South China Sea

Cold seeps are natural “outcrop” evidence of marine gas hydrates and represent one of the most direct indicators of gas hydrate occurrence. This study used high-resolution 3D seismic data covering approximately 400 km2 in the deep-water southern Qiongdongnan Basin, northern South...

Chronic Nitrite Nitrogen Responses in Penaeus monodon: From Growth Phenotypes to Metabolic Hub Signaling

Nitrite nitrogen is a prevalent environmental stressor in intensive shrimp aquaculture that impairs growth and health, yet its chronic effects and underlying molecular mechanisms in Penaeus monodon remain incompletely understood. To address this, we exposed juvenile P. monodon (i...

Diversity and distribution of potential polyethylene terephthalate and polypropylene plastic-degrading bacteria communities in deep-sea cold-seep ecosystems

ABSTRACT Biodegradation represents a promising strategy for the remediation of marine plastic pollution. Notably, deep-sea cold-seep ecosystems nurture exceptionally abundant microbial hydrocarbon-degrading bacterial resources. Due to structural similarities between plastics and...

Temperature-dependent phage-bacterium coexistence strategy mediates the intestinal microbial community diversity in shrimp

The diversity of intestinal bacterial communities is closely associated with host health. Phage-bacterium interactions are key determinants of this diversity, and temperature represents a critical environmental factor influencing these interactions. At elevated temperatures, path...

In situ evidence of tiered adaptations buffering a chemosynthetic clam holobiont against environmental sulfide fluctuations

Deep-sea holobionts adapt to extreme environmental fluctuations, but the molecular mechanisms underlying resilience remain poorly understood. We investigated the vesicomyid clam Archivesica marissinica and its sulfur-oxidizing symbionts during sulfide shortage via in situ transpl...

Telluria xinjiangensis sp. nov., a Gram-negative bacterium isolated from ripe melon fruit and its genetic characteristics

Abstract Background The genus Telluria (family Oxalobacteraceae, phylum Pseudomonadota ) comprises phylogenetically and ecologically diverse bacteria recovered from environmental, clinical, and plant-associated habitats. However, representatives associated with fresh fruit remain...

Chronic carbonate alkalinity exposure impaired the mechanical properties of exoskeleton and the intestinal microbiota of juvenile Macrobrachium rosenbergii

Along with the global expansion of saline-alkali aquaculture, understanding the physiological adaptation of economically important species like Macrobrachium rosenbergii to alkaline stress is essential for sustainable aquaculture production. This study investigated the effects of...

AGPC: an Annual 500 m Gridded Population (1990–2020) for China incorporating 3D building volume dynamics

Gridded population datasets with long-term temporal coverage and fine spatial resolution are essential for earth system modelling, urban studies, and disaster risk assessment. However, existing population products often fail to adequately represent population distribution in vert...

Genomic and biological characterization of three lytic phages targeting Vibrio parahaemolyticus and their application in a raw salmon model

ABSTRACT Vibrio parahaemolyticus is a major seafood-borne pathogen that poses substantial threats to food safety and aquaculture. However, effective and food-compatible strategies for controlling this pathogen along the seafood supply chain remain limited. In this study, three no...

An Electrochemical Separation Process for Producing Battery-Grade FePO4 and LiOH·H2O Raw Materials from Spent LiFePO4

Abstract Along with lithium iron phosphate (LFP) batteries emerging as the core energy storage technology, the recycling of spent LFP batteries has become a critical challenge in establishing a sustainable energy storage industry. Current industrially deployed technologies typica...

Bacterial Diversity and Community Assembly in Deep-Sea Sediments: Observations from the Philippine Sea

Microorganisms are important components of marine ecosystems and are widely distributed across global marine sediments. Although studies on microbial communities in deep-sea sediments have been increasing worldwide, research in the Philippine Sea is still at an early stage. In th...
