Summary: Petroleum hydrocarbons are widely present in seawater, and their content and distribution in the Yellow Sea and Bohai Sea are of concern due to their high toxicity and persistent effects on the ecological environment. The study collected seawater samples from 10 sites in the two seas and analyzed the distribution of total petroleum hydrocarbons (TPH) and the diversity of oil-degrading bacteria. The TPH concentration at the sites met the China Grade II water quality standard, and the area showed obvious pollution from exogenous petroleum hydrocarbons. The study also found that certain bacteria had a good degradation effect on short-chain alkanes and phenanthrene.

Summary: Chlorinated ethene contaminants, particularly vinyl chloride (VC), pose a significant risk due to their mobility, persistence, and carcinogenicity. Traditional methods of assessing soil vapor intrusion risk may not effectively detect lower chlorinated VC, but phytoscreening has shown promise as a cost-effective alternative for indirectly detecting shallow underground contamination by higher chlorinated ethenes. This study demonstrated the efficacy of phytoscreening in detecting VC in trees near contaminated sites, challenging existing assumptions about its detectability and highlighting the potential for more effective screening compared to traditional soil gas methods.

Summary: In this study, the microbial community composition of hydrothermal plumes in the Northern Tonga arc and Northeastern Lau Basin was analyzed using multiple culture-independent techniques, with a focus on the autecology of Alcanivorax. Alcanivorax was found to dominate the community at two sites, despite no indication for hydrocarbon presence in the plumes. The high abundance and gene expression of Alcanivorax in these areas may be related to undiscovered hydrocarbon seepage from the seafloor, potentially resulting from recent volcanic activity.

Summary: This study conducted metagenomic analysis on industrially contaminated soils, revealing that the abundance of PAH degradation genes and taxa did not differ significantly between soils with different pollution levels. The most abundant taxa carrying PAH degradation genes were actinobacteria from the Terrabacteria group. In addition to well-known PAH degraders such as Gordonia and Rhodococcus, other microbes like Azoarcus, Burkholderia, and Variovorax were found to possess genes related to PAH degradation, highlighting the non-specific and multifunctional nature of metabolic pathways encoded in these microorganisms.

Summary: The health of oak trees is influenced by the abundance of ammonia-oxidizing bacteria (AOB) in the soil, with a positive correlation between AOB abundance and soil pH. In contrast, there is no clear relationship between the abundance of archaea (AOA) and tree health. The ratio of soil carbon to nitrogen (C:N) is a key factor influencing denitrifier abundance, with correlations with AOB regardless of tree health.

Summary: Stone surfaces, though seemingly uninhabitable, host microbial life that adapts to various harsh conditions by exhibiting resistance to environmental factors. Granite and granodiorite host distinct bacterial populations influenced by quartz mineral content, which plays a major role in structuring microbial communities. Other geochemical parameters such as ilmenite, albite, anorthite, and orthoclase components also impact community structure to a lesser degree than quartz. Core members of the stone microbiome community including Cyanobacteria, Rubrobacter, and Deinococcus were identified on both lithologies, with specific taxa like Sphingomonas, Geodermatophilus, and Truepera found predominantly in the granodiorite samples. Community diversity correlated with quartz mineral content indicates that microbial communities on quartz surfaces may be transient and regularly changing. This research expands our understanding of built-stone microbial community structure based on lithology and geochemistry.

Summary: This study investigated the stimulatory effect of a promising phytoremediation strategy on the cleanup of TPH-contaminated sediment. The results showed that planting S. heteroptera can effectively remove TPH from sediment, and this removal is enhanced by the addition of oil-degrading bacteria and/or N. succinea. Furthermore, the presence of N. succinea and oil-degrading bacteria can alleviate the TPH toxicity of S. heteroptera.

Summary: This study found that electroconvulsive therapy (ECT) can selectively induce structural plasticity of the amygdala and hippocampal sub-regions in patients with major depressive disorder (MDD), and these changes are associated with the antidepressant effects of ECT. Additionally, the volume of the hippocampus-amygdala transition area (HATA) can serve as a potential biomarker to predict the effectiveness of ECT.

Summary: The effects of electron beam irradiation on critical heat flux (CHF) of aluminum surfaces in downward-facing saturated flow boiling were investigated. It was found that although the contact angle decreased greatly after irradiation, no obvious CHF and heat transfer coefficient change was observed up to a total dose of 3000 kGy. The bubble coverage was calculated and believed to be strongly associated with boiling crisis. The insensitivity of CHF in aluminum may be related to easy oxidation on the aluminum surface. This finding may be helpful for future heat transfer design and anti-accident counter-measurements in radiation environments.

Summary: Changes in resting-state EEG microstate parameters were observed in patients with disorders of consciousness (DOCs) after high-definition transcranial direct current stimulation (HD-tDCS), indicating an improvement in consciousness. Specifically, the duration and coverage of class C microstates significantly increased in the responsive group (RE), while these changes have not been reported in the non-responsive group (N-RE). Our findings suggest that EEG neural signatures can be used to assess consciousness states, and that improvement in brain activity dynamics is associated with the recovery of DOCs.

Summary: This study aimed to investigate the modulatory effect of common variations in the oxytocin receptor gene (OXTR) on reward circuitry function and its relationship with empathy. Using functional connectivity and spontaneous local activity analyses in the nucleus accumbens (NAcc), the results showed that individuals with the rs2268493 TT genotype had lower functional connectivity between the NAcc and the medial prefrontal cortex (mPFC) as well as the inferior frontal gyrus (IFG). These findings suggest that common OXTR variations have a modulatory effect on the connection between the NAcc and the central hubs of empathic networks, providing insights into the neural basis of the modulatory effect of OXTR on empathic behavior.

Summary: This study focuses on the stimuli-responsive luminescence of a novel emitter, DCzPy, which emits bluegreen fluorescence in crystal form. Upon gentle grinding, the fluorescence intensity of DCzPy is significantly enhanced with a hypsochromic shift. The emission wavelength returns to its original value after heavy grinding. Moreover, DCzPy exhibits a large bathochromic-shifted and weakened fluorescence under isotropic compression. In film form, the thermoresponsive behavior of DCzPy changes the emission from green to blue. Based on this thermo-induced fluorescence switching, a two-dimensional code for information anticounterfeiting is successfully fabricated.

Summary: A novel emitter (DCzPy) was synthesized and its stimuli-responsive luminescence was studied. The emitter showed bluegreen fluorescence in the crystalline state, with dramatically enhanced and hypsochromic-shifted fluorescence upon gentle grinding. The emission wavelength returned to the original state after further heavy grinding. Under isotropic compression, the emitter exhibited a large bathochromic-shifted and weakened fluorescence. In addition, in the film state, the emission color of the emitter changed from green to blue as the temperature increased.

Summary: The wide application of excimer materials in the OLED field is mainly driven by the regulation of their stacking structure. This study designed three anthracene derivative molecules with sterically hindered substituents and prepared crystals with different aggregating structures to investigate the relationship between their structures and properties. The study found that under high pressures, these anthracene groups exhibit enhanced fluorescence during the formation of excimers, while the ones that have already formed excimers under ambient conditions show a wider red-shift range. The piezochromic fluorescence behavior observed indicates that regulating the aggregation mode of anthracene groups can meet different application requirements and guide the expansion of excimer materials' usage.
