Summary: This study compared the life-cycle impacts associated with various management alternatives for recovering energy and nutrients from the organic fraction of municipal solid waste. It found that mass burn waste-to-energy and gasification scenarios generally have the lowest environmental impacts, while landfilling and gasification Fischer-Tropsch have the greatest impacts. Sensitivity analyses suggest that these conclusions are generally robust to uncertainty in input values.

Summary: This study investigated the feasibility of using coconut shell waste-based activated carbon for ammonium stripping and adsorption, achieving almost complete removal of NH3-N and 90% removal of COD at optimized conditions. However, for effluents with COD higher than 200 mg/L, further biological processes are needed for complete removal of refractory compounds.

Summary: The integration of phototrophic microalgal production and anaerobic digestion can recycle excess nutrients across European surplus hotspots to produce protein-rich biomass for nutritional applications. Improved growth of Desmodesmus sp. and Chlorella vulgaris was observed in paper-filtered digestate compared to membrane-filtered digestate, highlighting the importance of balanced growth medium for digestate utilization. Using paper-filtration as a pre-treatment technique showed promising results in maximizing digestate recycling and delivering a sustainable animal feed-grade protein alternative.

Summary: This article discusses the optimization of microalgae cultivation using landfill leachate as a nitrogen source. The results show that microalgae Chlorella sp. can achieve higher biomass concentration when grown in a medium containing 0.08 g/L nitrogen from landfill leachate. The chemical composition of the microalgae biomass is suitable for producing bioactive nitrogen fertilizer without heavy metals. The use of microalgae suspension can also reduce the moisture content in fertilizer production.

Summary: In order to meet the global demand for fertilizers, there is an urgent need to recover macro-nutrients from non-conventional sources. Sludge reject water, a by-product of sewage sludge dewatering, is considered an ideal feedstock for bioelectrochemical nutrient recovery. By mixing sludge reject water with livestock wastewater, the recovery and up-concentration of macronutrients can be optimized, leading to increased current output and NH4+ concentration factor.

Summary: A combined technique of microalgae photosynthesis and dark fermentation was proposed to efficiently reclaim nutrients and COD from landfill leachate, and convert microalgae biomass into biohydrogen and VFAs. The interaction between Scenedesmus obliquus and Chlorella vulgaris was enhanced by extracellular polymeric substances (EPS), leading to better absorption of nutrients and higher energy yield. This work fills the knowledge gaps of dual microalgal interactions and provides insights for the disposal of landfill leachate and bioenergy production.

Summary: Psychological science has traditionally viewed a good life in terms of happiness or meaningfulness. However, it is suggested that psychological richness, characterized by various interesting experiences, should also be considered as a neglected aspect of a good life. This study explores the unique causes and correlates of happiness, meaning, and psychological richness, and proposes that predictors of a psychologically rich life differ from those of a happy or meaningful life.

Summary: The savanna theory of happiness suggests that the human brain's evolutionary constraints influence our sensitivity to situations and circumstances that impact our happiness. This theory proposes that individuals with lower intelligence may be more affected by these factors. Darkness, as it represented danger to our ancestors, could still decrease our happiness today, particularly among more intelligent individuals.

Summary: In this study, four marine microalgae with different cell sizes were harvested using pilot-scale ultrafiltration. The permeate fluxes ranged from 16.75 to 33.75 L/m2h, with the smallest cell size (Synechococcus) having the lowest flux and the largest cell size (Tetraselmis) having the highest flux. The concentrating factors ranged from 39.2 to 46.6, with the highest concentration achieved for Synechococcus. The energy requirement for harvesting varied from 16.44 to 28.48 GJ/tonne biomass, with smaller cell sizes requiring less energy.

Microalgae, as a renewable energy resource, have high photosynthetic efficiencies and biomass productivity and can be converted into various biofuels. However, challenges exist before broader commercial application of microalgae as a bioenergy feedstock, such as strain selection, biomass pre-concentration techniques, and utilization of wet microalgal biomass. This article reviews the current research status and future perspective of microalgal biofuels.

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.
