Summary: The research findings demonstrate that in various animals, methylmercury cysteinate complexes can be transformed into selenocysteinate complexes, potentially involving the binding to selenoprotein P and formation of mercury selenide, providing new insights into mercury detoxification mechanisms.

Summary: This review paper comprehensively illustrates the leaching mechanisms of chemicals from microplastics in both biotic and abiotic environments. It identifies flame retardants, plasticizers, and antioxidants as the main chemicals that leach from microplastics and have the potential to disrupt endocrine functions and cause health issues. The review also highlights diffusion and partitioning as the main leaching mechanisms.

Summary: The organic matter in mangrove sediments accelerates the degradation of methylmercury, leading to lower levels of methylmercury observed. Sulfate-reducing bacteria play a significant role in methylating mercury.

Summary: The study found that seabirds detoxify methylmercury by demethylation in the liver and preferential excretion of heavier isotopes in feathers during molt, depending on species-specific strategies and dietary exposure levels. Higher Hg isotope variations in feathers than internal tissues suggest different detoxification processes and offer a powerful approach for investigating Hg metabolism in seabirds.

Summary: Genome editing tools are being widely used to improve crop resistance and quality, particularly in tomatoes. Researchers have successfully manipulated many genes to enhance tomato tolerance to abiotic stresses. The genome editing technologies, such as CRISPR/Cas9, are considered fast and efficient for crop improvement.

Summary: Anthropogenic mercury undergoes long-range transport to the Arctic and can be transformed into methylmercury, potentially leading to high exposure in Arctic inhabitants and wildlife. Biogeochemical and ecological processes in the Arctic play a crucial role in determining the environmental exposure of mercury, particularly the bioavailability, methylation and demethylation, bioaccumulation, and biomagnification of methylmercury. Recent scientific advances have provided insights into these processes and highlighted their importance in understanding the fate of anthropogenic mercury in Arctic ecosystems.

Summary: Photochemical demethylation of DMHg is an important source of MMHg in sunlit water. Experimental data shows that DMHg is readily degraded by photochemical processes in different natural waters and artificial seawater. The degradation rate of DMHg is comparable to or exceeds that of MMHg in most waters.

Summary: The accumulation and elimination of per- and polyfluoroalkyl substances (PFAS) in wildlife and humans are largely due to interactions with proteins such as organic anion transporters, fatty acid binding proteins, and serum proteins like albumin. Changes in the environment and physiological factors can impact the distribution of PFAS-related proteins and subsequently affect PFAS levels. Understanding these relationships between biotic and abiotic environments, protein levels, and PFAS concentrations can improve study design and interpretation in wildlife research.

Summary: Elevated CO2 has been shown to have positive effects on plant growth and metabolic processes, but can also negatively impact crop quality. The effects of elevated CO2 on plants vary under different biotic and abiotic stresses, influencing phytohormone concentrations and secondary metabolite production.

Summary: Travertine-depositing hot springs are good natural laboratories to study the precipitation of carbonate minerals. They can be categorized into near-neutral pH hot springs and hyperalkaline hot springs, and contain different microenvironments. Both abiotic and biotic processes can drive carbonate formation. Calcite and aragonite are the most common minerals, and their polymorphism is influenced by bulk water chemistry. Solute transport in microenvironments and local changes can significantly modify carbonate precipitation and polymorphism. Further research is needed to better understand carbonate precipitation in hot springs.

Summary: Research on travertine-depositing hot springs has shown that both abiotic and biotic factors can influence the precipitation of different carbonate minerals, with water chemistry and microenvironments playing crucial roles. Future studies focusing on microenvironments are needed to deepen our understanding of carbonate precipitation in hot springs and potentially provide insights for other environments.

Summary: The excessive use of chemical fertilizers due to population growth and food demand has negatively affected soil fertility. In response, scientists have turned to plant growth-promoting rhizobacteria (PGPR) for sustainable farming. These bacteria release volatile organic compounds (VOCs) that enhance plant growth and defense mechanisms.

Summary: This review discusses the plant growth promotion (PGP) mechanisms of Bacillus amyloliquefaciens (BA) and its current limitations in agriculture. BA can improve soil nutrient availability, change soil microbial community, secrete hormones and volatile organic compounds (VOCs), and enhance plant resistance against biotic and abiotic stresses. Future studies should focus on the nutrient uptake mechanisms of plants in different soil conditions.
