Summary: Electrochemical reduction of CO2 (CO2RR) is a versatile technology for sustainable chemical production. In this study, CH-derived biochar is utilized to improve the performance of CO2RR by enhancing electrode conductivity. The effect of different pyrolysis temperatures on biochar fabrication and catalytic electrode performance is investigated. A life cycle assessment is conducted to compare the sustainability of CH-derived biochar and fossil fuel-derived electrode materials.

Summary: This study investigated the interactive effects of microplastics, biochar, and earthworms on greenhouse gas emissions and soil microbial functional genes in vegetable-growing soil. The addition of biochar alone or combined with microplastics decreased soil CO2 emissions, while microplastics and biochar inhibited CO2 emissions and promoted N2O emissions in the presence of earthworms. The interactions of these substances also had significant effects on soil chemical properties and microbial abundances.

Summary: This study demonstrates that the responses of soil microbial communities in Mediterranean croplands to biochar amendment are more significant than to climate manipulation. Soil chemical properties, enzyme activities, and the relative abundances of bacterial populations are not responsive to the interaction of biochar and climate manipulation, while the predicted functionality of the bacterial community is modified by both factors. Climate manipulation produces changes in the composition of the soil fungal community, with a significant impact on soil beta-glucosidase activity and microbial biomass.

Summary: Accumulating evidence suggests that climate warming is reducing soil organic carbon in drylands, but there is a lack of research on particulate and mineral-associated organic carbon pools. This study examined the effects of simulated climate change and initial biocrust cover on soil carbon accumulation and quality in a dryland ecosystem. The results showed that warming and reduced rainfall increased soil organic carbon, especially particulate organic carbon, but only in soils with low biocrust cover. In soils with high biocrust cover, climate change did not affect soil carbon. Biocrust communities were found to mitigate the negative effects of climate change on soil organic carbon.

Summary: By analyzing over 1300 topsoil samples, we found that warmer arid and tropical ecosystems, particularly in less developed countries, have the lowest contents of multiple soil micronutrients. We also provide evidence that temperature increases may result in abrupt reductions in soil micronutrient content when a temperature threshold of 12-14 degrees Celsius is crossed, potentially affecting 3% of the planet over the next century. Our findings have important implications for understanding the global distribution of soil micronutrients and their impact on ecosystem functioning, rangeland management, and food production in the warmest and poorest regions of the planet.

Summary: The sustainability of Mediterranean croplands is threatened by climate warming and rainfall reduction. The use of biochar as an amendment represents a tool to store organic carbon (C) in soil. This study focused on the distribution of soil organic matter (SOM) into particulate organic matter (POM) and the mineral-associated organic matter (MAOM) and investigated the effects of climate change and biochar application on these fractions. The results revealed an increase in thermal stability in both POM and MAOM fractions after biochar addition, and the MAOM fraction was particularly enriched in labile substances.

Summary: This study analyzed the effect of temperature and residence time on the properties of vineyard pruning waste derived biochar. The results showed that temperature had a clear influence on the biochar's properties, while residence time had a weaker effect. Increasing temperature improved various properties of the biochar, but reduced organic carbon concentration and certain element contents. Prolonged residence time increased ash and fixed carbon content, and decreased H/C and O/C ratios. The hydrophysical properties of the biochar were suitable as a growing media component, and the concentration of polycyclic aromatic hydrocarbons was below international standards. The germination index increased with temperature and decreased with residence time.

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.
