Summary: Multi-omics analyses were used to study the molecular changes in microbial communities under different conditions. Using five omics layers, the study mapped the molecular response of a synthetic community of gut bacteria to three non-antibiotic drugs. The results showed that the omics methods were consistent in estimating relative species abundances and complemented each other in capturing functional changes.

Summary: Microbial communities in the ocean play crucial roles in various biogeochemical processes and ecosystem functions. Assessing their diversity is important for understanding their structure and function. This study explores the use of deep learning tools and a novel residual network architecture to classify marine microbial communities without reliance on curated phylogenetic trees. Results show that machine learning approaches still face challenges in terms of time, compute power, and microbial genomic diversity. Improvements can be made by addressing genome coverage and class imbalance, developing alternative models, and increasing accessibility of resources for model training and refinement.

Summary: This study estimated the major sources and sinks of total mercury (THg) and methylmercury (MeHg) in Kongsfjorden using the SERAFM model. The model was calibrated based on the physical properties of the fjord, Hg runoff coefficients, transformation rate constants, etc., and validated against measured data. The results showed that tidal inflow and glacial runoff were the main sources of THg, while tidal inflow and in situ methylation in shallow halocline water were the main sources of MeHg.

Summary: This study investigated the microbial diversity and community composition of soil samples collected from different sites along the urbanized region of the Potomac River. The results revealed the presence of marine soil bacteria as well as bacterial taxa associated with urbanization and waste runoff. Commonly identified taxa were found to be associated with agricultural pollution, organochlorine pesticide contamination, and bromochloromethane pollution. The study also highlighted significant variations in microbial diversity across sampling sites, indicating the influence of environmental factors. These findings have important implications for understanding the impact of urbanization on soil microbial communities along the Potomac River and can guide management and preservation strategies for these ecosystems.

Summary: Utilizing global environmental DNA sampling projects and constructing hidden Markov models, we identified the potential of global microorganisms to degrade plastics and compiled a catalogue of nonredundant enzyme homologues with the ability to degrade 10 different plastic types. We found that ocean and soil enzyme abundance relates to depth and plastic pollution, and the abundance of these enzymes correlates significantly with marine and country-specific plastic pollution trends.

Summary: Understanding how microbial communities adapt to environmental stresses is crucial for interpreting ecological patterns and microbial diversity. In this study, we investigated the hypolithic communities in the Gobi Desert and found that hypolithic colonization rates decreased with increasing drought gradient. We also observed different community compositions in the hot and cold seasons, with cold communities dominated by Cyanobacteria and hot communities dominated by Proteobacteria and Firmicutes. Cold communities had stronger functions in photosynthesis and carbon metabolism. Our findings suggest that the hypolithic communities in the Hexi Corridor of the Gobi Desert may follow a seasonal developmental cycle.

Summary: The Indian monsoon circulation plays a crucial role in transporting mercury pollution from South Asia to the Himalayas and Tibet Plateau region. A study found a strong overlap between Lake Gokyo and Indian anthropogenic sources, indicating the source of mercury from South Asia. The findings suggest that transboundary atmospheric transport can transport mercury from South Asia northwards to at least the Tanglha Mountains in the northern Himalaya-Tibet.

Summary: A novel strain of Streptomyces, designated 3_2(T), was isolated from soil in the black Gobi rock sample of Northwest China. This strain showed high similarities to other members of the genus Streptomyces and exhibited resistance to high salt concentrations. Genomic analysis revealed the presence of multiple genes responsible for environmental stress response, as well as gene clusters associated with the production of secondary metabolites exhibiting inhibitory activity against certain bacteria. Therefore, this strain represents a new species, Streptomyces halobius sp. nov.

Summary: South Asian biomass burning is crucial for the heavy springtime air pollution over the Tibetan Plateau, contributing significantly to aerosol components. The transboundary transmissions of these aerosols are regulated by large-scale westerly winds and regional mountain-valley winds. In addition to worsening air quality, aerosols from South Asian biomass burning also lead to temperature decrease and precipitation reduction, posing a threat to the fragile ecosystem of the Tibetan Plateau during springtime.

Summary: This study analyzed the changes in river discharge and sea ice in the Kara and Laptev Seas from 1979 to 2019. The results showed that there were significant increases in discharge and heat from the rivers, while the sea ice concentration decreased. The changes in discharge and riverine heat mainly affected the initial and final stages of sea-ice melting. The cumulative riverine heat from May to September had a large impact on the sea ice changes in the Kara and Laptev Seas. However, the contribution of river discharge changes to the reduction in sea ice concentration was limited at annual scales.

Summary: Heavy metal contamination in soils at a Zn-Pb mineral processing plant in Longnan, China poses a serious threat to human health and global pollution. Different levels of heavy metal contamination have varying effects on microbial communities. Statistical analysis revealed higher average levels of all detected metals (Zn, Pb, As, Cu, Cd, Hg) in the soil compared to the background value, with Pb and As being the most serious contaminants. The heaviest contamination occurred in the raw material stacking area and production area. Closer proximity to the wastewater discharge area corresponded to higher heavy metal content and greater pollution. Microbial community diversity decreased with increasing heavy metal concentrations, but fungi showed no significant change. Cu, Cd, Hg, and pH were identified as the main factors affecting microbial community composition. Actinobacteria and Gemmatimonadetes were negatively correlated with Cu, Zn, Cd, and Pb at the uncontaminated level, while Proteobacteria and Chloroflexi were significantly correlated with pH and Hg at the severely contaminated level. However, heavy metal contamination had minimal impact on dominant fungi. In conclusion, microbial communities such as Proteobacteria, Actinobacteria, Chloroflexi, and Ascomycota exhibited greater tolerance to heavy metals, providing important insights for the remediation of heavy metal-contaminated soils.

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.

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.
