Abstract ：
Cropland fragmentation (CLF) studies often overlook bidirectional land transformations. This study reassesses county-level CLF in China (1990-2023) using a 30 m-resolution Landsat-based dataset and a novel Modified Landscape Division Index to capture both cropland gains (transfer-in) and losses (transfer-out). We find pronounced CLF increases in urbanized plains, notably the Huang-Huai-Hai Plain (6.13 x 10(-2) y), Northeast China Plain (3.69 x 10(-2) y), and Sichuan Basin (4.97 x 10(-2) y), driven primarily by urbanization (39.5% contribution to CLF from impervious surfaces). Conversely, cropland gains from forests and grasslands mitigate fragmentation, with forest-to-cropland conversion reducing CLF by 40.3%. Counties with CLF increases due to losses outnumber those with decreases by 5.5 times. Regression analysis reveals strong correlations between area changes and CLF (p < 0.01). These insights are relevant for urbanizing regions globally, such as Southeast Asia and Sub-Saharan Africa, highlighting the need for policies like zoning regulations and reforestation incentives to balance urban expansion with cropland restoration for sustainable land use and food security.

Abstract ：
Electric fields in sediments and soils are critical yet overlooked drivers of microbial ecology. This review examines the importance of electrotaxis in shaping microbial community dynamics and ecology models, surpassing traditional frameworks centered on chemotaxis. We analyze evidence that electric field gradients influence microbial community structure, function, and biogeochemical cycles in natural environments. Current mechanistic models, primarily based on eukaryotic systems, insufficiently explain bacterial electrotactic responses, necessitating new conceptual frameworks that integrate electrochemical and biological perspectives. We also evaluate its applications in environmental and microbiome engineering, with future research recommendations and methodologies in electrotaxis research. This synthesis aims to establish electrotaxis as an essential consideration in microbial ecology, presenting both challenges and opportunities for advancing our understanding of microbial ecosystems.

Abstract ：
Nanobiohybrids for solar-driven methanogenesis present a promising solution to the global energy crisis. However, conventional semiconductor-based nanobiohybrids face challenges such as limited tunability and poor biocompatibility, leading to undesirable spontaneous electron and proton transfer that compromise their structural stability and CH4 selectivity. Herein, we introduced eutectic gallium-indium alloys (EGaIn), featuring a self-limiting surface oxide layer surrounding the liquid metal core after sonication, integrated with Methanosarcina barkeri (M. b). The well-designed M. b-EGaIn nanobiohybrids exhibited superior performance, achieving a maximum CH4 yield of 455.64 +/- 15.99 mu mol g(-1), long-term stability across four successive 7-day cycles, and remarkable CH4 selectivity of >99 %. These improvements stem from enhanced proton-coupled electron transfer involving hydrogen atoms at the core-shell interface, further facilitated by the elevated expression of hydrogenases at the abiotic-biotic interface. This study provides an insightful concept for nanobiohybrid design through multi-interface engineering, advancing sustainable and scalable CO2-to-biofuel conversion under ambient conditions.

Abstract ：
Agglomeration of plastic nanoparticles (NPs) is a natural process in aquatic systems, governed largely by water composition. When NPs agglomerate, their migration can be inhibited due to enhanced gravitational settling, which promotes the formation of NP clusters and facilitates their accumulation.In this paper, the agglomeration of nanoplastic particles was modeled by coupling the population balance equation (PBE) model with the extended-DLVO (XDLVO) theory. A wide range of water compositions and the effects of UV radiation were considered to provide a comprehensive analysis.Data on hydrodynamic particle diameter from the literature were selected and used to validate the model.The model contains physical parameters of the investigated systems and an adjustable parameter, such as the initial number of particles in suspension, which was not available in the datasets. Overall, the model demonstrates strong agreement with experimental measurements and successfully captures the influence of chemical and biological compounds in water, as well as the effects of sunlight.This model has significant potential applications. It can be integrated into mathematical frameworks to predict NP transport in surface water and groundwater systems. Additionally, it could guide the design and operation of advanced filtration units and be extended to predict colloid-facilitated transport of dissolved contaminants associated with NPs in aquatic environments. © 2025, The Authors.

Abstract ：
Agglomeration of nanoplastic particles (NPs) is a natural process in aquatic systems and it is governed largely by water composition and plastic polymer type. When NPs agglomerate, gravitational settling is enhanced, inhibiting NPs migration in soil and water bodies and therefore favoring NPs accumulation in sediments and on riverbeds. In this paper, the agglomeration of NPs was modeled by coupling the population balance equation (PBE) model with the extended-DLVO (XDLVO) theory. A wide range of water compositions and the effects of UV radiation were considered to provide a comprehensive analysis. Measurements of the evolution of hydrodynamic particle diameter over time in conjunction with physico-biochemical parameters of the investigated systems were taken from the literature and used to validate our calculations. Overall, the model demonstrates strong agreement with experimental measurements and successfully captures the influence of chemical and biological compounds in water, as well as the effect of sunlight. The model has the potential to be integrated into mathematical frameworks to predict NP transport in surface water and groundwater. Additionally, it can guide the design and the operation of advanced filtration units where NP agglomeration could improve removal.

Abstract ：
Hyperthermophilic composting (HTC) is a promising strategy for the treatment of organic solid waste, leveraging extreme thermophilic conditions (up to 90 degrees C) driven by specialized microbial communities. While microbial community composition and succession have been previously described during HTC, the metabolic activity and adaptation of thermophilic microbiomes remain largely unexplored. In this study, we conducted time-series metagenomic and metatranscriptomic analyses on samples from a full-scale HTC system to characterize the composition, functional potential, and metabolic activity of thermophilic bacteria. A total of 227 non-redundant metagenome-assembled genomes (MAGs) were recovered, including 45 thermophilic MAGs (optimal growth temperatures > 45 degrees C). Metatranscriptomic profiling revealed that thermophilic taxa-such as Thermus thermophilus, Planifilum fulgidum, and Thermaerobacter spp.-were highly transcriptionally active and played vital roles in heat generation through the upregulation of energy production and carbohydrate metabolism pathways. Additionally, these thermophiles exhibited survival and adaptation strategies involving physiological changes (e.g., spore formation, enhanced motility, and genome streamlining) and the induction of thermal resistance mechanisms (e.g., DNA repair systems, heat-shock proteins, and synthesis of compatible solutes). Overall, this study provides novel insights into the diverse survival strategies of thermophilic microbiomes in HTC and suggests potential avenues for optimizing thermophilic biotreatment processes for solid waste management. IMPORTANCE Despite increasing interest in hyperthermophilic composting as a sustainable waste treatment strategy, the mechanisms by which microbial communities both tolerate and drive extreme thermal conditions remain unclear. This study fills a critical knowledge gap by identifying a small group of highly active thermophilic bacteria that dominate during peak composting temperatures and orchestrate endogenous heat production. Using genome-resolved multi-omics, we demonstrate that these thermophiles couple high metabolic output with specialized survival strategies-such as genome streamlining, thermotolerance systems, and adaptive motility systems. These findings advance our understanding of microbial function under extreme conditions and provide a framework for optimizing thermophilic microbiome performance in engineered ecosystems.

Abstract ：
It has been previously shown that devices based on microbial biofilms can generate hydrovoltaic energy from water evaporation. However, the potential of hydrovoltaic energy as an energy source for microbial growth has remained unexplored. Here, we show that the electroautotrophic bacterium Rhodopseudomonas palustris can directly utilize evaporation-induced hydrovoltaic electrons for growth within biofilms through extracellular electron uptake, with a strong reliance on carbon fixation coupled with nitrate reduction. We obtained similar results with two other electroautotrophic bacterial species. Although the energy conversion efficiency for microbial growth based on hydrovoltaic energy is low compared to other processes such as photosynthesis, we hypothesize that hydrovoltaic energy may potentially contribute to microbial survival and growth in energy-limited environments, given the ubiquity of microbial biofilms and water evaporation conditions. Devices based on microbial biofilms can be used to generate hydrovoltaic energy from water evaporation. Here, Ren et al. show that, in addition, electroautotrophic bacteria can use evaporation-induced hydrovoltaic electrons for growth in biofilms.

Abstract ：
Accumulating evidences are challenging the paradigm that methane in surface water primarily stems from the anaerobic transformation of organic matters. Yet, the contribution of oxygenic photosynthetic bacteria, a dominant species in surface water, to methane production remains unclear. Here we show methanogenesis triggered by the interaction between oxygenic photosynthetic bacteria and anaerobic methanogenic archaea. By introducing cyanobacterium Synechocystis PCC6803 and methanogenic archaea Methanosarcina barkeri with the redox cycling of iron, CH4 production was induced in coculture biofilms through both syntrophic methanogenesis (under anoxic conditions in darkness) and abiotic methanogenesis (under oxic conditions in illumination) during the periodic dark-light cycles. We have further demonstrated CH4 production by other model oxygenic photosynthetic bacteria from various phyla, in conjunction with different anaerobic methanogenic archaea exhibiting diverse energy conservation modes, as well as various common Fe-species. These findings have revealed an unexpected link between oxygenic photosynthesis and methanogenesis and would advance our understanding of photosynthetic bacteria's ecological role in the global CH4 cycle. Such light-driven methanogenesis may be widely present in nature. This study has revealed a widespread yet previously undiscovered link between oxygenic photosynthesis and methanogenesis and will advance our understanding of the ecological role of photosynthetic bacteria in the global CH4 cycle.

Abstract ：
Hydrovoltaic electricity generation, being demonstrated through various forms of water movement, holds great promise for advancing green energy technologies. However, the natural transpiration of plant leaves, as the largest water flux on land accumulating immense latent energy, has rarely been directly harvested. Here we present a living leaf transpiration generator using a lotus leaf, enabling direct harvest of latent energy via leaf transpiration. The leaf transpiration generator demonstrated sustained all-day electricity generation, featuring an open-circuit voltage of 0.25 V and a short-circuit current of 50 nA, which was effectively amplified in series or parallel connections. Partial least squares path modelling analysis indicated that improved electricity generation was attributed to enhanced transpiration rate, stomatal conductivity and temperature, while increased relative humidity had a counteractive effect. This study not only uncovers the unprecedented hydrovoltaic effect of leaf transpiration but also provides a fresh perspective for advancing green energy technologies through the widespread phenomenon of leaf transpiration.

Abstract ：
Mechanical energy as a main energy form in wastewater treatment plants is generally used to enhance the physical mixing of reactor compartments. However, utilizing mechanical energy for directly driving microbial metabolism has not been explored. Here we developed an innovative mechano-driven bio-denitrification approach, whereby the electronic energy produced from mechanical energy by piezoelectric materials supported the metabolism of denitrifying microorganisms. When autotrophic denitrifying bacterium Thiobacillus denitrificans was stimulated with in situ formed struvite under mechanical agitation, a powerful cellular piezo-sensitization enabled nearly 100% nitrate reduction in synthetic wastewater with H2O as the electron donor. Such a self-sustained bio-denitrification process powered by mechanical energy was successfully implemented in real wastewater treatment, resulting in a maximum 117% increase of nitrate removal. These findings introduce a new paradigm for wastewater denitrification, unveiling previously unappreciated mechanisms for the energy-microbe-element nexus during wastewater treatment, and offer crucial insights for optimizing wastewater treatment plant operation.
