Summary: This study evaluated the toxicity of tungsten disulfide (WS2) nanosheets on nitrogen-fixing cyanobacteria and found that WS2 exposure disrupted the metabolic pathways related to energy metabolism, sulfur-containing amino acids, fatty acids, and antioxidants in the cyanobacteria. The exposure also resulted in oxidative stress and lipid peroxidation. These findings highlight the potential ecotoxicity of WS2 nanomaterials and the need for caution in their application and environmental release.

Summary: The study focused on the dynamic algal cross-feeding properties of a genetically-modified Azotobacter vinelandii strain with varied levels of glutamine synthetase accumulation. By manipulating the overaccumulation of GS and transitioning cells into a noninducing medium, the researchers observed effects on bacterial growth, ammonium-excretion, and cross-feeding with algae. The behavior of the bacterial population could be finely tuned for multiple bacterial cell generations, but eventually faster-growing cells with no ammonium excretion arose, highlighting the need for further genetic engineering improvements for safe and effective N-biofertilizer use in an open environment.

Summary: Soil N-2-fixing bacterial communities are essential for nitrogen cycling, and silver nanoparticles can significantly affect their diversity and richness, with pH value potentially playing a role in the relationship. The effects of silver nanoparticles on these communities may be mediated by released silver ions, with particle size being the key factor influencing their inhibition.

Summary: This study investigates the relationship between tree-ring delta N-15 and soil N dynamics in N-2-fixing red alder trees, and explores the influence of alder-fixed N on neighboring conifers. The findings suggest that the delta N-15 values in tree-rings can reflect N accretion rates in red alder and provide insights into the nitrogen dynamics under different tree species combinations.

Summary: The community assembly processes of UCYN-A are mainly driven by stochastic processes, accounting for 66-92%, with temperature and coastal/oceanic position as the principal environmental factors. The close linkage between assembly processes and UCYN-A abundance, diversity, and drivers provides clues to the unusual global distribution of UCYN-A.

Summary: This study examined the effects of nitrogen addition on soil nitrogen-fixing bacteria (NFB) diversity in degraded alpine meadow soils on the Tibetan Plateau. Results showed significant differences in dominant bacterial species between different slopes. The diversity indices of NFB did not differ significantly between slopes, except for the Shannon index. Interestingly, N addition had no effect on NFB diversity or the abundance of dominant bacteria, but it did lead to significant changes in some low-abundance NFB. The composition and diversity of NFB were significantly correlated with slope and soil physicochemical properties.

Summary: Nitrogen-fixing cyanobacteria play a significant role in maintaining the nitrogen pool of paddy fields. However, the fate of NFC-N and its application in rice fields have not been extensively studied. The results of the experiment showed that NFC-N is mainly retained in the topsoil and combining NFC with chemical nitrogen fertilizers could achieve a more optimized management effect.

Summary: Hard materials usually lack energy dissipation mechanism and self-healing ability, but nature solves this problem by creating multiscale interfaces between high-contrast materials like minerals and biopolymers. Inspired by the enamel-dentin junction in nature, researchers have developed an enamel-like crown with beta-FeOOH nanocolumns and a flexible self-healing layer. The top iron oxide layer has high modulus and hardness, while the bottom layer allows for energy dissipation and self-healing. The biomimetic tooth replicate shows promising adhesive properties and inhibits tooth decay-causing bacteria, making it a potential dental material.

Summary: A novel sandwich-type biosensor was developed using an AuNPs-modified glassy carbon electrode to enable electrochemical testing at a relatively high potential range. By applying an ultra-fast redox pulse, reversible oxidation of Au was alleviated, allowing for stable electrochemiluminescence (ECL) signals to be generated. Unique mechanisms were observed at different potentials, and a specific ECL reaction route involving the analyte, azithromycin, was proposed. This study provides a promising approach for the application of Au-based sandwich-type biosensors in environmental monitoring.

Summary: This study examines the interactions between polystyrene microplastics (PS) and increasing CO2 concentration in the plant-soil system. Results show that PS interferes with rice absorption of Fe, Mn, and Zn, and increases the abundance of bacteria involved in nitrogen turnover and urease activities. Elevated CO2 enhances rice photosynthesis, decreases nitrogen-fixation bacteria, and alters bacterial co-occurrence patterns. Combined exposure of PS and elevated CO2 significantly decreases rice stomatal conductance and transpiration rate, and affects soil bacterial amino acid metabolism.

Summary: This study investigated the transformation of dissolved organic sulfur (DOS) during the oxic process in municipal wastewater treatment plants (WWTPs) in China. Two groups of WWTPs were identified based on DOS variations, with some WWTPs showing decreased DOS concentrations in effluents and others showing increased DOS concentrations. The study highlights the importance of focusing on the transformation and control of DOS in the oxic process.

Summary: Electrochemical oxidation (EO) is an effective method for treating dissolved organic matter (DOM) in landfill leachate. The use of nonactive boron-doped diamond (BDD) anode has demonstrated the best performance for DOM oxidation. The decrease of Abs420 can be used as an indicator of the shift from the humic acid-like fraction (HA) to the proteinaceous biopolymer fraction (BP) during the EO treatment with BDD anode.

Summary: Climate change impacts soil microbial communities and their genetic exchange, affecting the transfer of antibiotic resistance genes (ARGs) among bacteria. However, the effects of elevated CO2 on soil antibiotic resistome are not well understood. In this study, a field experiment using a free-air CO2 enrichment system was conducted to investigate the responses of ARGs profiles and bacterial communities to elevated CO2 and sulfadiazine (SDZ) amendments in soils. The results showed that SDZ exposure induced the co-occurrence of certain resistance genes, and elevated CO2 weakened the effects of SDZ on the abundance of ARGs. Furthermore, elevated CO2 decreased the abundance of certain resistance genes and reduced the stimulation of SDZ on the dissemination of certain resistance genes.

Summary: In this study, a coal gangue recognition method based on modal fusion of RGB and infrared is proposed to improve the accuracy of coal gangue recognition and the recognition of mixed gangue rate. A fully mechanized coal gangue transportation test bed is built, and RGB and infrared images are obtained. Classification networks including AlexNet, VGG-16, and ResNet-18 are constructed with modal feature fusion. The results show that ResNet networks achieve higher classification accuracy on RGB and infrared image data compared to AlexNet and VGG-16 networks. The feasibility of the modal fusion method in coal gangue recognition is verified with a recognition rate of 97.92%.
