Summary: This study conducted comprehensive chemical and microphysical observations on a persistent fog-haze process in the northern suburbs of Nanjing in 2013. It compared and analyzed the characteristics and variations of volatile organic compounds (VOCs) under different weather conditions and discussed the factors influencing VOCs during extremely dense fog. The results showed that the concentration of VOCs differed significantly under different weather conditions, mainly due to the boundary layer characteristics and photochemical reaction rate. The enhanced collision and deposition of fog droplets also played a role in removing VOCs from the atmosphere.

Summary: The study finds that the cold air outbreak is effective in reducing air pollution during winter in northern and eastern China, but air pollution tends to rapidly reappear during the decay phase. The properties of the residual cold air mass, such as depth, heat content, and slope of isentropes, are related to the reappearance of air pollution. The large-scale circulation patterns in the initial stage of the cold air outbreak can also serve as a precursor for the rapid reappearance of air pollution.

Summary: A severe haze-fog episode occurred in the Yangtze River Delta region of eastern China in November 2018. Observations showed changes in PM2.5 mass concentration, convective planetary boundary layer height, and air humidity during and after the fog days. The fog top cooling induced a potential temperature jump, limiting the development of the planetary boundary layer during daytime after fog dissipation. The wet deposition of fog on PM2.5 was found to be negligible, and aerosols were liberated from fog droplets to the atmosphere after fog dissipation.

Summary: This study measured the vertical profiles of particulates in Macao during a dust event using a 355 nm Mie scattering lidar. The results showed high aerosol concentrations in the atmosphere, which were consistent with trajectory analysis and ground-based measurements. The study also found that the correlation between PM2.5 and TSP varied with the intensity of the dust storm, and large particles dominated the aerosols during the dust episode. Additionally, the results revealed high aerosol concentrations at altitudes where the dusty aerosols were transported from northern China, Shanghai, and the Taiwan Channel to the Pearl River Delta Region.

Summary: Rising temperatures affect forests at different scales, with significant vertical variation across forest strata. This study evaluates the vertical variation in microclimate, leaf temperatures, traits, and gas exchange in forests, and discusses the implications for tree and ecosystem ecology. Integrating these patterns and mechanisms into models is critical for predicting forest-climate feedback as the climate continues to change.

Summary: Vertebrates rely on rods and cones in the retina for visual information. Fishes have evolved different numbers and amino acid compositions of cone opsin genes and show phenotypic plasticity in their expression profiles to adapt to diverse light environments. The Western mosquitofish demonstrates quick reactions in cone opsin expression to altered photic properties and is able to maintain foraging efficiency under distinct light environments. The phenotypic plasticity in cone opsin expression profiles may explain the successful colonization of a wide range of aquatic habitats by Western mosquitofish.

Summary: This study investigated the responses of maize inbred lines with different levels of drought resistance to drought stress and exogenous glycine betaine (GB) treatment. The results showed that drought treatment inhibited growth and development in the drought-sensitive inbred line, while the drought-tolerant inbred line exhibited no significant differences compared to the control. Exogenous GB mitigated the effects of drought stress in both lines. Transcriptome analysis revealed differentially expressed genes (DEGs) in response to drought stress, and the expression patterns of selected DEGs were validated using qRT-PCR. This study provides insights into the potential mechanisms of drought tolerance in maize and the role of exogenous GB in regulating drought tolerance.

Summary: Nitrous acid (HONO) is an important radical precursor that can impact secondary pollutant levels in urban environments. This study developed a new one-dimensional chemistry and transport model to better simulate the formation processes and ground sources of HONO, improving predictions of its diurnal variation and vertical distribution. The results showed that photolysis of surface HNO3/nitrate and photo-enhanced NO2 conversion are the main daytime sources of HONO, while at night, the main source is NO2 hydrolysis.

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: 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.
