Summary: The study aimed to identify conditional reference demographic indicators of Daphnia magna populations for bioassays. It was found that groups with a density of 25 individuals/dm(3) exhibited the best demographic characteristics, but maintenance conditions and nitrate concentration in the cultivation water were crucial factors affecting the state of the populations. Regular monitoring of demographic characteristics can enhance the accuracy of bioassay results.

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 molecular mechanisms of chronic aquatic toxicity induced by different surface functional groups of graphene nanomaterials are studied using RNA sequencing. Unfunctionalized graphene (u-G) causes potential oxidative stress in Daphnia magna by altering ferritin transcription levels in the mineral absorption signaling pathway. Functionalized graphenes, including carboxylated graphene (G-COOH), aminated graphene (G-NH2), hydroxylated graphene (G-OH), and thiolated graphene (G-SH), have toxic effects on Daphnia magna through various metabolic pathways. The findings provide important insights into the safety assessment of graphene nanomaterials.

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: 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: A geochemical model combined with parametric fitting techniques was used to investigate the solidification/stabilization mechanisms of Pb-rich pyrite ash in ordinary Portland cement and calcium aluminate cement. The study revealed that ettringite and calcium silicate hydrates have strong affinities for Pb under alkaline conditions. When the hydration products are unable to stabilize all the soluble Pb, part of it may be immobilized as Pb(OH)2. Hematite from pyrite ash and newly-formed ferrihydrite, along with anglesite and cerussite precipitation, are the main controlling factors of Pb under acidic and neutral conditions. This work provides valuable insights for the development of more sustainable mixture formulations in solid waste remediation.

Summary: In recent years, noncoding RNA molecules have been discovered to play a potential role in gene regulation as components of endogenous DNA-RNA hybrid triplexes. These triplexes, which are involved in complex molecular signaling networks, hold the key to engineering biological computing components. In this study, researchers successfully constructed triplex-based molecular gates, including XOR, XNOR, and a threshold gate, through the transcription of a fluorogenic RNA aptamer. These biomolecular-integrated systems demonstrated precise modulation over a wide range of transcriptional outputs, showcasing the potential for developing molecular gates using DNA-RNA triplex nanostructures.
