Summary: This study highlights the importance of fully characterizing SiO2NS materials, as surface modifications may enhance their toxic potential. Exposure to all NSs resulted in alterations in the microvilli and mitochondria of D. magna intestine, as well as damage to egg cells. The possible Trojan horse effect was also observed, particularly in the case of chronic exposure.

Summary: Organisms with wide distribution ranges that adapt to drastically different habitats over space and time are well suited for studying ecotype formation. By studying Crustacean model Asellus aquaticus, researchers found genetic regions associated with body pigmentation, antennae length, and body size in surface stream, cave, and lake ecotypes. Genomic differentiation between natural populations and genes potentially associated with different habitats demonstrate how troglomorphic adaptations can be used as a model for related ecotype formation.

Summary: This study investigated the uptake, acute toxicity, and depuration of ZnO nanoparticles using the model fresh water organism Daphnia magna. The results showed that the toxicity of the nanoparticles depended on their size and the presence of surfactant. Contrary to previous reports, the study did not detect any depuration of ZnO nanoparticles after exposure.

Summary: In this study, Raman confocal spectroscopy-microscopy was used to successfully detect amine-functionalized and carboxy-functionalized polystyrene nanoparticles in Daphnia magna. Transmission electron microscopy confirmed the presence of these nanoparticles in the gastrointestinal tract of the organisms. It was found that carboxy-functionalized polystyrene nanoparticles could disrupt the epithelial barrier of the GI tract to a minor extent, while amine-functionalized polystyrene nanoparticles showed no overt cytotoxicity. This study demonstrates the feasibility of using label-free confocal Raman mapping to study the behavior of nanoparticles in a biological system.

Summary: The attention to rare earth oxide nanoparticles, including yttrium oxide (Y2O3), has increased in many fields due to their unique structural characteristics and functional properties. The aim of our study was to investigate how bio-corona formation on Y2O3 NPs affects their environmental fate and toxicity. Y2O3 NPs induced toxicity to Daphnia magna at particle concentrations of 1 and 10 mg/L, regardless of particle size, but the formation of an eco-corona reduced their toxic effects toward D. magna at higher particle concentration by interacting with naturally excreted biomolecules.

Summary: Experimental study on processing multicomponent nanopowders of the W-C system obtained by plasma-chemical synthesis in a microwave electromagnetic field with a frequency of 24 GHz has shown that nanosized particles of tungsten carbide can be formed during microwave treatment. The influence of processing parameters on the phase composition, morphology, and specific surface area of nanopowders has been investigated, revealing that microwave processing can significantly reduce the time of chemical transformations and lead to the formation of tungsten monocarbide while maintaining particle size in the nanometer range.

Summary: This study investigated the combined effects of food abundance and zinc oxide (ZnO) nanoparticles concentration on the development and reproductive performance of Daphnia magna. The results showed that high levels of ZnO nanoparticles and low abundance of algae had a negative effect on the life history of D. magna. Higher abundance of algae reduced the negative effect of ZnO nanoparticles, but the negative effect could not be eliminated. The findings highlight the importance of considering food abundance when evaluating the impact of pollutants on zooplankton.

Summary: This study aimed to investigate the effects of sonication on the acute toxicity and swimming behavior of polystyrene nanoparticles using Daphnia magna as the test organism. Results showed a 2-fold reduction in acute toxicity after sonication, possibly through the formation of an eco-corona on the nanoplastic surface. Additionally, mean swimming distance was reduced for both sonicated and non-sonicated samples.

Summary: Tungsten carbide nanoparticles (nano-WC) play a significant role in composite materials due to their physical and chemical properties. However, the limited studies on the cytotoxicity of nano-WC have been addressed. In this study, the cytotoxic impact of tungsten ions (W6+) on cells was evaluated and it was found that W6+ exerted a significant cytotoxic influence. This study provides valuable insight into the toxicological mechanisms underlying the exposure of lung cells to nano-WC, reducing the environmental toxicant risk to human health.

Summary: The study shows that prey exhibit active responses against predators, developing different morphological traits in response to different threats. Prey can discriminate between predators and produce countermeasures, adjusting their morphology and life-history traits to adapt to the existing predator regimes. When faced with conflicting threats from a combination of predators, prey develop intermediate, trade-off responses in all morphological traits to cope with the multiple predator pressures.

Summary: Ecological stability is a complex concept that involves multiple dimensions of functional and compositional responses to environmental change. Our study introduces an integrative metric of overall ecological vulnerability (OEV) that captures both functional and compositional aspects, providing a framework for assessing ecological risk and management. The findings highlight the importance of considering multiple stability components and their relationships in understanding ecosystems' vulnerability to environmental change.

Summary: There is a growing interest in ecotoxicological studies on the effects of polystyrene nanoparticles on aquatic organisms. However, improvements can be made in terms of particle characterization in the test medium, purification of nanoparticles before toxicity studies, and emphasis on size characterization. Short-term or direct exposure scenarios may not provide the most environmentally relevant knowledge on the toxicity of polystyrene nanoparticles.

Summary: Metal and metal oxide nanoparticles can induce ROS formation through various mechanisms, such as corrosion, photochemistry, and interactions with biomolecules. These interactions can affect the properties of the nanoparticles and their ability to generate ROS, ultimately impacting living organisms. Kinetic aspects, solution chemistry, and NP characteristics play important roles in the ROS mechanisms and formation.

Summary: The physicochemical characterization of AMPs revealed their complexity in size, shape, and chemistry. The AMPs exhibited concentration-dependent effects on the cytoskeleton, mitochondria, and cell membranes. Metabolomics and lipidomics analysis provided insight into the inflammation-related metabolites and extensive membrane remodeling induced by AMPs. Overall, AMP exposure resulted in internalization, oxidative stress, cytoskeleton disruption, mitochondrial activation, membrane remodeling, and metabolic reprogramming of lung epithelial cells and macrophages. Integrating Cell Painting with metabolomics and lipidomics offers an advanced nanosafety methodology to capture cellular and molecular phenotypes and understand the biological mechanisms of (nano)particle exposure.

Summary: This study demonstrates that the addition of 2% by weight of MoS2 to Mo feedstock significantly improves crack mitigation in Mo-based micro-lattice structures produced by selective laser melting. The enhanced crack inhibition is attributed to the formation of Mo2S3, reduced lattice strain, and decreased residual stresses. The addition of MoS2 hinders stress corrosion cracking and surface oxidation cracking, as confirmed by increased polarization resistance. However, it also leads to increased corrosion current density and occurrence of different types of corrosion. The strategy of adding MoS2 to Mo feedstock enables the fabrication of high-temperature micro-lattice components with improved corrosion resistance properties.

Summary: Although the impact of climate warming on the success of invasive species in freshwater ecosystems is not well understood, this study shows that invasion success doubles with climate warming, indicating a substantial increase in successful establishment of invaders in the future. Furthermore, the species richness increased after the invasion under warming conditions, but not under present climate conditions. This study, which uses advanced eDNA methodologies, provides important insights into how climate warming may affect invasive species and can inform management recommendations in adapting to climate change.
