Summary: The study investigated the impact of food resources with varying C/N ratio, lipid, and omega 3-PUFA content on the fitness of three Collembola species. The results showed species-specific responses in biomass and survival rate to different diets, with wide dietary C/N ratios and roots having a negative impact on Collembola. Mixing diets mostly resulted in intermediate results, with only mixes of resources favored by Collembola in the wild showing synergistic positive effects.

Summary: By comparing the trophic structure of shallow lakes in tropical and subtropical regions in South America, researchers found that despite lower fish biomass in tropical lakes, there was no significant impact on zooplankton or phytoplankton communities. The study suggests that warming will have relatively minor impacts on the pelagic trophic structure of shallow subtropical lakes, supporting the idea of weaker trophic cascades in warm (sub)tropical lakes compared to temperate ones.

Summary: Microbes in the soil play a dominant role in the biodiversity of the planet, but there are still some shortcomings in the current research on their diversity. To address these issues, studies on soil microbiomes should be more comprehensive in terms of targeted taxa and resolution, integrate functional information with taxonomic information, and combine temporal analysis with spatial analysis.

Summary: By assessing the food assimilation of two common European anuran species at different stages using a stable isotope approach, it was found that there is a strong segregation of trophic niches for both larvae and postmetamorphic juveniles, which helps reduce potential intraspecific competition and promotes long-term co-existence of these syntopic anurans.

Summary: In coastal marine food webs, food chain length and trophic level distribution are crucial elements of ecosystem-based management. This study evaluates the hypothesis that high primary production leads to lower trophic levels and shorter food chain length in British Columbia coast. The results support this hypothesis, showing a significant inverse relationship between primary production and food chain length as well as trophic level.

Summary: Dietary metabarcoding technology has greatly improved the analysis of animal diets, but technical limitations, such as uneven DNA amplification, hinder its application. This review explores various approaches to overcome the predator problem, from deeper sequencing to excluding predator DNA during PCR, and their potential impact on multipredator-taxon studies. The use of multiprimer strategies that prioritize both depth and breadth of prey detection is suggested as a partial solution, although multitaxon studies still require further consideration. Alternative methods for reducing the prevalence of predator DNA are also discussed, highlighting the need for additional empirical examination.

Summary: This study investigated the exposure levels of trace metals and metalloids among a group of gardeners in an allotment garden, and found high concentrations of lead, cadmium, and arsenic in their blood and urine samples, which were higher than those of the local population living on contaminated soils. The study suggests that these gardeners are at risk of chronic kidney diseases due to co-exposure and additive effects of these contaminants.

Summary: Studies have shown that microplastics ingestion by wild freshwater fish increases with urbanization, although a direct correlation with surrounding water microplastics concentration has not been identified. Microplastics were found in all published articles, with more than 50% of specimens analyzed in one study showing microplastics presence. Additionally, microplastics were found in the gills of fish, and there is evidence that they can translocate to different tissues of the organism.

Summary: The widespread use of heavy metals and antibiotics in livestock farming and their subsequent presence in agricultural soils pose significant problems for human health and the environment. This study investigated the tolerance and co-tolerance of bacterial communities in soils polluted with heavy metals and antibiotics. The findings suggest that bacterial communities in polluted soils exhibit increased tolerance and co-tolerance to both heavy metals and antibiotics, which has important implications for understanding the transmission of antibiotic resistance genes to human pathogens.

Summary: This study demonstrated that Cu2O microparticles were rapidly dissolved to copper ions inside cells, followed by lysosome-mediated exocytosis. Smaller microparticles had a lower uptake rate but dissolved more quickly, leading to faster exocytosis activation. The rapid release of copper ions resulted in immediate toxic effects, mainly through necrosis, while glutathione buffering ability alleviated copper toxicity. The turnover of intracellular copper was much faster at sublethal exposure levels, but the labile copper(I) concentration only increased by a maximum of 2 times. Tolerance to copper-based nanoparticles depended on their ability to discharge released copper ions.

Summary: In this study, the intracellular fate of CuO nanoparticles (NPs) was investigated using gold-core labeling and Cu ion bioimaging technologies. It was found that the dissolution rate of CuO NPs depended on the cell type, with limited transformation of Cu(II) to Cu(I) occurring within the cellular microenvironment. Instead, Cu(II) was rapidly eliminated from the cells through the GSH-mediated pathway and lysosome exocytosis. The labile Cu(I) level in cancerous cell lines was immediately regulated upon Cu exposure, explaining their tolerance to Au@CuO NPs. These findings have important implications for assessing the health risks of CuO NPs.

Summary: Growing evidence suggests that microorganisms exhibit heterogeneous sensitivity to toxicants, but the mechanisms behind this remain unclear. This study confirmed the heterogenous responses of Chlamydomonas reinhardtii to Cu stress, and found a link with the cell cycle. The increase in labile Cu(I) was related to cell division, leading to fluctuations in labile Cu(I) with diurnal and cell cycles. Cu influenced the cell cycle and algae at different cell phases exhibited different Cu sensitivities. This study reveals the underlying mechanisms of heterogeneous Cu sensitivity in phytoplankton and can help assess the ecological risks of Cu.

Summary: In this study, we used in situ techniques to reveal the dissolution process of Cu2O nanoparticles in freshwater. Our findings indicate that cubic Cu2O nanoparticles have a higher dissolution quantity compared with spherical nanoparticles of the same surface area. The difference is mainly attributed to the crystal surface, while other factors like particle size or aggregation status have minor effects. We also demonstrated the simultaneous growth of new small nanoparticles and the dissolution of pristine Cu2O nanoparticles during the dissolution process. The solubility of cubic Cu2O nanoparticles is significantly reduced under O2-limited conditions, suggesting that the O2 concentration largely affects the dependence of dissolution on nanoparticle morphology. Our study highlights the potential application of in situ techniques in tracking the environmental fate of metal-oxide-based nanoparticles, providing important information for assessing the ecological risks of engineered nanoparticles.

Summary: Due to the COVID-19 pandemic, billions of people wear face masks daily, but the potential risks of hazardous materials released from these masks remain largely unexplored. This study evaluates the leachability and cytotoxicity of copper nanoparticles in face masks for the first time. The results show that inhalation of copper from the mask accounts for around 3% of the total copper, and a significant amount of copper attached to the fibers can be easily released into solution. The released copper causes cellular stress and oxidative damage. These findings underscore the need for careful assessment of the leaching of nanoparticles in face masks.

Summary: Divestiture is a commonly used policy tool for mitigating negative market effects of mergers. Recent studies have provided empirical evidence supporting the effectiveness of divestiture mechanisms. A case study on the 2013 merger between Anheuser-Busch InBev and Grupo Modelo found that divestiture led to a small but significant increase in the price of the divested brands. The findings highlight the importance of idiosyncratic market details that can significantly impact the effectiveness of using divestiture to address negative market effects of mergers.

Summary: This study found that bone mesenchymal stem cell-derived exosomes (BMSC-exos) can alleviate sepsis-induced acute respiratory distress syndrome (ARDS) by reversing mitochondrial dysfunction and reducing alveolar epithelial cell (AECII) apoptosis. BMSC-exos can restore mitochondrial biogenesis and inhibit p-Drp1-mediated mitochondrial fission by promoting Nrf2 expression. Additionally, BMSC-exos improve the survival rate, reduce inflammatory cytokine storm, and alleviate lung damage in sepsis mice. These findings provide a new mechanism and potential therapeutic strategy for sepsis-induced ARDS.

Summary: This article systematically discusses the cellular journey of engineered nanomaterials (NMs), including internalization, intracellular trafficking, and deposition/exocytosis, highlighting that the accumulation of NMs in cells depends not only on their crossing of the cell membrane but also on subsequent trafficking and exocytosis processes. A deeper understanding of the cellular journey of NMs implies an alternative strategy to fabricate specific targeting NMs by bypassing certain intracellular pathways for potent therapeutic effects with minimal toxicity.
