Fire, the most frequent disaster in human society, often results in property damage and casualties, posing a significant threat to public safety and societal development. While flames and smoke are commonly associated with fires, few realize that toxic gases generated during combustion are among the primary causes of fire-related injuries and fatalities. Understanding the "chemical secrets" within fire smoke becomes crucial. This paper employs an anthropomorphic and exaggerated narrative approach, depicting a tale of planetary exploration, to educate readers on the toxic gases commonly encountered in fires and how to safeguard against their harmful effects.

The plasma samples of 49 CHB patients, 43 CHB-related LC patients and 50 CHB-related HCC patients were analyzed using the Hitachi L-8900 amino acid analyzer. The differences in amino acid levels were compared between groups. Simultaneously, the MetaboAnalyst website was used to analyze the relevant amino acid metabolism pathways. Results A total of 16 amino acids with different expression levels were identified. During the development from CHB to HCC, plasma levels of cystine, phenylalanine and glycine gradually increased, while the ratio of branched chain amino acids/aromatic amino acids gradually decreased. Compared with the CHB and the LC groups, levels of taurine, methionine, tyrosine, ornithine, glutamate, isoleucine and tryptophan were significantly increased in the HCC group, while the level of arginine was significantly lower. Compared with the CHB group, levels of serine, alanine and proline were higher in the LC and the HCC groups, while the level of valine was also higher in the HCC group (all P＜0.05). The metabolic pathway analysis of three groups showed significant changes in various metabolic pathways, including phenylalanine, tyrosine, tryptophan biosynthesis, phenylalanine metabolism, glycine, serine, threonine metabolism, valine, leucine, isoleucine biosynthesis, and taurine metabolism. In addition, by constructing a network diagram of amino acid enzyme gene interactions, a total of 79 metabolic enzyme genes related to amino acid expression were discovered. Conclusion Plasma levels of amino acids are of certain guiding significance for early warning and prognosis of HCC and can provide a theoretical basis and methodological basis for the diagnosis and treatment of HCC in the future.

Biochar is one of the most important carbon-rich minerals with a porous structure in the carbon sequestration, immobilization of metal and organic contaminants, as well as soil fertility improvement. However, its large-scale use is very limited in the agriculture and environment, due to the high cost of production and transportation from agricultural biowaste to plant. In this study, a new technology was explored to directly convert from agricultural biowaste to biochar in the field. The local applications had significantly reduced the costs of biochar. Inspired by nature, biochar production was also proposed in the field, where only agricultural biowaste, water, and fire were required for biomass carbonization and charcoal formation; Specifically, Litchi branches sourced from subtropical regions were utilized as feedstock to explore an on-site production of biochar. Soil (Ferralsols) slurry was applied as a coating and quenching agent to create an oxygen-limited environment during fire-water coupled carbonization of the feedstock. This self-limiting oxidation approach was used to minimize the expenses of production, transportation, and utilization. Biochar that was produced with soil slurry coating and quenching also displayed the highest carbon content (83.5%) and carbon capture capacity (83.9%), exceeding unconverted biomass and biochar produced without coating by 16.7% and 37.8%, respectively. The burning process of Litchi branches was divided into three stages: 1) Surface was charred immediately but with an unburned core; 2) Surface was grayed out, while the core was in a self-ignition state with high temperature and limited oxygen, and the dark red char fell to the ground; and 3) The dark red char gradually burned out to be ash. Spraying water on the dark red char was used to prevent the occurrence of the 3rd stage, thus favoring the formation of biochar instead of ash. Furthermore, the soil coating likely acted as a barrier, thus reducing carbon monoxide or carbon dioxide release during combustion. Additionally, the soil integration was facilitated to form the mineral-carbon composite for the carbon capture. Scanning electron microscopy and energy spectroscopy analysis show that the regular structure of the carbon skeleton was observed after coating and quenching the iron-aluminum slurry. The iron-aluminum minerals were also loaded on the surface. A novel approach to carbonization accelerated a paradigm shift in biochar production from a sophisticated stationary facility to a simple way for practical use in the field. Low cost greatly contributed to the agricultural and environmental application of biochar. The economically viable combination of fire and soil (Ferralsols) slurry coupled carbonization can be expected to provide valuable insights for biochar adoption and carbon neutrality. In conclusion, the readily available agricultural residues and soil-based coatings can be integrated to mitigate the environmental impact of biochar production, in order to enhance the efficacy as a carbon capture. These findings can offer significant implications for the broader adoption of biochar as a sustainable solution, in order to promote climate and soil health. [ABSTRACT FROM AUTHOR]

Modern education often puts the development of intelligence as priority and ignores the subjective feelings such as emotions and desires. By tracing the western knowledge tradition, Professor Jim Garrison points out that different kinds of love and desire are closely related to wisdom since Plato. Education of eros which leads to the desire for goodness is necessary for practical wisdom. Practical reasoning is rationality with passion. John Dewey develops this idea and sets up his holism thoughts, which rejects the idea of dualism. Based on his holism idea, Dewey connects with eastern thoughts of Confucianism, Daoism and Buddhism. For teachers, emotion is the sub-function of the body-heart-mind. Teachers must lead their eros to desire the good things for themselves and for students. If teachers ignore emotions of themselves and their students, they will suffer from the dis-functional operation of their souls. It will then harm the artistic and creative expression and moral development of both teachers and students. [ABSTRACT FROM AUTHOR]

The Eastern Pacific Equatorial region is an important fishing ground for China, and there is a close relationship between mesoscale eddies and the distribution of fishing grounds. In this study, a vector geometry method based on flow field was used to identify mesoscale eddies in the Eastern Pacific Equatorial region （85°W-125°W, 5°S-5°N） using 2012-2018 meteorological satellite remote sensing data and filtering out vortices with a lifespan longer than one week. The spatial distribution, radius range, lifecycle, migration path, and velocity of mesoscale eddies in this region were analyzed. The relationship between the eddy and the fishing ground distribution was also discussed. The results showed that the number of anticyclonic eddies in the Eastern Pacific Equatorial region was greater than that of cyclonic eddies. The eddy lifecycle was relatively short, with the majority lasting no more than one week. The eddy radius was mainly concentrated in the range of 250-310 km, and the migration velocity was mainly concentrated at 6-18 m/s, with a migration distance of 25-50 km. There were two regions, called as "tropical regions," near the 5°N and 5°S, which exhibited more frequent eddy activity, while near the equator, there were almost no eddies present. Additionally, some characteristics of the eddies （period and radius） showed obvious interannual variations. These findings provide a basis for analysis of fishing ground formation, temporal and spatial distribution, and the development of fishing forecasts in the Eastern Pacific Equatorial region.

Microplastics (MPs) refer to plastics with a diameter of less than 5 mm. As a new environmental pollutant, MPs can enter the body through the respiratory tract, digestive tract and skin, and then deposit in multiple tissues such as the intestine, liver and ovary. MPs exposure has toxic effects on the female reproductive system by affecting follicle development, oocyte quality and sex hormone levels through apoptosis, oxidative stress and disorders of hypothalamic-pituitary-gonadal axis, thereby reducing female fertility. Moreover, recent studies have found that MPs can enter the placenta and lead to the abnormal placental metabolism, immune imbalance at the maternal and fetal interface, and the impaired placental structure. MPs can further enter the offspring through the placental barrier after maternal exposure to MPs, causing adverse effects on the neural, digestive, reproductive and other multiple systems of the offspring. Given the toxicity of MPs and the persistence in environment, the exposure to MPs should be reduced in daily life to prevent human from the harm of MPs. [ABSTRACT FROM AUTHOR]
