Summary: The 16S rRNA gene is widely used as a marker to study the evolutionary relationships and microbial composition. However, it has limitations such as variable copy numbers, intragenomic heterogeneity, and low taxonomic resolution, causing biases in estimating microbial diversity. This study analyzed prokaryotic genomes and found that the 16S rRNA gene copy number ranged from 1 to 37 in bacteria and 1 to 5 in archaea, with intragenomic heterogeneity in 60% of genomes. The study also calculated the overestimation and underestimation of microbial diversity using different regions of the 16S rRNA gene.

Summary: Electrolytic manganese residue poses potential threats to the environment and requires eco-friendly treatment. Composting has been found to effectively passivate heavy metals and mitigate their ecotoxicity. Inoculation of Phanerochaete chrysosporium promotes the passivation of manganese, prolongs the thermophilic period, and enriches the microbial community structure.

Summary: This study investigated the bacterial communities at different depths of the Arabian Sea OMZ using high-throughput sequencing. The results showed high bacterial diversity in deep waters and sediment samples, with less richness at the core OMZ depths. Bacterial community composition varied with depth and dissolved oxygen levels, and predictive functional annotation suggested the presence of active nitrogen, sulphur, carbon, and methane metabolic cycles. The study also revealed the presence of nitrogen reduction bacterial group below the core OMZ depths, which may provide insights into the expansion of OMZ region in Arabian Sea.

Summary: This article presents a microbial diversity survey of the hydrothermal vents in Straitene Hydrothermal Field (SHF) in northern Iceland. The study reveals that the community members from the vent fluids are predominantly aerobic heterotrophic bacteria, while the chimneys contain diverse habitats with putative acetogenic, sulfur-cycling, and hydrogen-metabolizing taxa. The inhabitants of SHF show more similarity to terrestrial hot spring samples than other marine sites.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
