Summary: The study investigates how viruses interact with their vector, the varroa mite, and how these interactions affect viral epidemiology. Through transcriptomic analysis and experimental validation, it is found that virus abundances are positively correlated and viruses that coexist interact with the vector's gene co-expression modules in a similar way. Furthermore, silencing candidate genes leads to a reduction in varroa gene expression and a change in viral load.

Summary: Microbial co-occurrence network analysis is widely used in plant microbiome research, but challenges remain in representing natural microbial communities and extracting ecological and evolutionary insights from the networks. This perspective highlights the kingdom-level bias in network representation and interpretation, and suggests using cross-kingdom co-occurrence networks to increase representability. The paper also recommends three approaches for ecological interpretation to overcome oversimplified interpretation of the networks.

Summary: The study investigated the biogeography and assembly mechanisms of active bacterial and archaeal communities in marine sediments from the Bohai Sea, South Yellow Sea, and the north East China Sea. It revealed higher heterogeneity in community activities than abundances, with clear geographic patterns and a greater role of deterministic processes in community assembly. Additionally, intertaxa competition was found to be the dominant interaction between active bacterial and archaeal members, contributing to dispersal limitation.

Summary: Microscopic resolution is crucial for studying the spatial structure and interactions of microbial communities. This study investigates the microbial interactions at the micron-scale in anammox consortia and reveals the significant role of biotic interactions in the assembly of anammox communities. The results suggest that there is no statistically significant symbiotic interaction between anammox bacteria and other heterotrophic populations, and the conservative metabolic cooperation among Brocadia species may be regulated by quorum sensing with secondary messenger c-di-GMP.

Summary: In this study, the influence of polytetrafluoroethylene content and distribution on liquid transport behaviors in gas diffusion layers and the performance of proton exchange membrane fuel cells was investigated. The results indicate that an increased content of polytetrafluoroethylene favors liquid removal, but an extremely high content could weaken cell performance. Additionally, a reasonably higher polytetrafluoroethylene content in the inlet region of the gas diffusion layer benefits water drainage enhancement.

The findings show that the insertion of the perforated plate increases the output power of the generator and an optimal installation position exists. Furthermore, the position of the perforated plate affects the voltage evenness of the modules, with the most uniform voltage distribution observed when the plate is in the middle of the third row of modules.

Summary: This study reconstructs the microstructure of carbon fiber-type GDL with different degrees of aging using a stochastic algorithm, and investigates water transport within the reconstructed GDLs using a multiphase lattice Boltzmann method. The results show that as the GDL ages, its water elimination performance decreases significantly, leading to water retention. The degradation of polytetrafluoroethylene (PTFE) makes the GDL more hydrophilic, causing a more severe water flooding problem. A moderate increase in PTFE content improves GDL antiaging performance, while excessive content reduces the effective porosity and fuel cell performance.

Summary: A new type of internal-arc thermoelectric leg is proposed to overcome the contradictory relationship between thermoelectric efficiency and thermal stress in solar thermoelectric generators (STEGs). The new leg shows excellent power output and lower thermal stress compared to the rectangular leg. The best configuration for STEGs depends on the concentration ratio, with the X-type leg preferred for lower ratios and the inner-arc type preferred for higher ratios. Further optimization of the inner-arc type leg can significantly increase the critical power density.

Summary: This study investigates the effect of cation exchange resin (CER) on the sequential recovery of hydrogen and methane from anaerobic digestion (AD) and the corresponding mechanisms. The results show that CER can simultaneously enhance the production of hydrogen and methane by promoting the solubilisation, hydrolysis, and acidification of organic matter. Additionally, CER facilitates effective contact between bacteria and organic particulates and reduces the energy barrier for mass transfer during methane production. The study also reveals changes in the microbial community structure and metagenomics during the AD process.

Summary: The fouling of seawater reverse osmosis membranes is a persistent challenge in desalination. This study monitored the operational performance of a desalination plant for 7 years and the fouling development in different areas of membrane modules. The findings showed that operational performance declined over time and fouling mainly occurred at the feed side of the modules, with the highest microbial diversity. Keystone species like Chloroflexi and Planctomycetes played an important role in maintaining community structure and biofilm maturation. Polysaccharides, soluble microbial products, marine humic acid-like substances, and inorganic substances contributed to fouling. Overall, biofouling had a significant impact on membrane fouling after 7 years of operation.

The results showed successful transition from flocculent-activated sludge to well-defined AGS after two months of operation. The primary pathways for pollutant removal were simultaneous nitrification, denitrification, and phosphorus removal. Moreover, the incorporation of internal separators induced shifts in the flow pattern, which promoted granulation.

Summary: By synergizing organic carbon source, thiosulfate, and zero-valent iron, efficient mixotrophic denitrification of oligotrophic secondary effluent can be achieved. Thiosulfate plays a vital role in promoting TN removal efficiency, while corrosion of Fe0 releases OH- to neutralize H+ from thiosulfate-driven denitrification, creating a suitable environment for denitrification. The coordination of thiosulfate and Fe0 maintains the dominance of Thiobacillus for denitrification.
