Summary: A new method named Shield and Vortex 1-2 (SAV1-2) was established to extract spatial texture information from sun glitter observed from satellites. The method was used to extract sea surface texture detail information around Diaoyu Dao and its affiliated islands. The results showed stable shield effects and Karman vortex streets upstream and downstream of the islands, with the dominant direction of the Kuroshio Current being east. The study also analyzed the changes in water temperature, color, and chlorophyll a concentration.

Summary: Microalgae cannot fulfill the bait demand for aquaculture due to limitations in light intensity and other unfavorable conditions. This study selected 6 mixotrophic microalgae and screened for the optimal strains and organic carbon sources. Thalassiosira pseudonana and Chlorella sp. were found to be suitable for mixotrophic culture. When glycerol was added, Thalassiosira pseudonana showed a 1.67-fold increase in maximum cell density compared to the photoautotrophic group, while Chlorella sp. exhibited a 1.69-fold increase with acetic acid. Metabolomic analysis revealed that mixotrophic bait microalgae could promote the accumulation of lipids and amino acids.

Summary: In this study, the morphological and histological characteristics of the pharyngeal sac in Pampus argenteus were examined using histochemical techniques and electron microscopy. The pharyngeal sac showed unique characteristics such as well-developed muscular walls, weakly keratinized epithelium, numerous goblet cells, and needle-like processes on the papillae. RNA-seq analysis revealed that phenotype-associated genes were upregulated, while genes related to nutrient digestion and absorption were downregulated in the pharyngeal sac.

Summary: Aluminum (Al) toxicity is a serious threat to root formation and crop growth due to soil acidification. This study focused on the effect of Al3+ on citrus roots in acidified red soil. The results showed that rapid soil acidification occurred in pomelo orchards, and optimized fertilization and liming treatments effectively reduced Al toxicity in roots and increased yield by improving soil pH and base saturation. Structural equation modeling confirmed the importance of increasing soil pH and base saturation while decreasing exchangeable Al for citrus production in acidic soil.

Summary: This study investigated the effects of different concentrations of chloroquine (CQ) on large yellow croakers and found that higher concentrations of CQ led to more obvious toxic effects, resulting in high mortality rates. The study also observed differential expressions of autophagy/inflammation/apoptosis-related genes in representative tissues.

Summary: In this article, we examine how autocratic regimes, in particular China, use political propaganda to facilitate policy reversals of major significance. Through analyzing extensive propaganda materials, we find that the Chinese Communist Party employs a systematic, precise, multi-dimensional, and multi-layered discursive engineering project to reverse its policies effectively. This coordinated maneuver of state narrative is key in achieving the smooth and successful policy reversal.

Summary: This work systematically studies the 2D alpha-In2O3 monolayer and finds that it has a stable configuration and good oxidation resistance. It is identified as a semiconductor with a direct bandgap of 1.41 eV, making it a promising candidate for modern gate technologies. The alpha-In2O3 monolayer also exhibits excellent optical absorption coefficient and superior out-of-plane piezoelectric response, making it useful for field-effect phototransistors and out-of-plane piezoelectric devices.

Summary: In this study, the effects of seven light treatments on the growth and physiological parameters of juvenile Sinonovacula constricta were investigated. The results showed that yellow light had the highest growth rates, while violet and blue light had the lowest. Yellow light also promoted feeding activity and enzymatic activity related to digestion. Moreover, yellow light exhibited higher antioxidant biomarker activities and red light had higher expression levels of genes related to antioxidation and stress response. Conversely, white light had the lowest malonaldehyde level. Overall, these findings suggest that yellow light is beneficial for the growth of juvenile S. constricta.

Summary: Allium chinense G. Don, known as Ganoderma of vegetables, has been used historically to treat blood stasis syndrome and reduce brain damage caused by reduced oxygen-carrying capacity. The anti-hypoxic effect of A. chinense was investigated using a mouse model of cerebral anoxia, and 16 compounds were isolated, showing potential anoxia-tolerant activity in vitro. These compounds also regulated oxidative stress markers and suppressed the expression of inflammatory proteins. This study provides a new nutritional strategy for A. chinense against cerebral anoxia and altitude illness.

Summary: This study revealed that the heat shock transcription factor PtHSF1 positively regulates the synthesis of triacylglycerol and fucoxanthin in Phaeodactylum tricornutum. Overexpression of PtHSF1 increased the contents of triacylglycerol and fucoxanthin and upregulated key enzyme genes involved in their biosynthesis pathways. Gene silencing of PtHSF1 had the opposite effect. This study provided insights into the regulation mechanisms of PtHSF1-mediated triacylglycerol and fucoxanthin synthesis.
