Summary: Novel anti-bacterial copper telluride (CuTe) nano-clusters with superior bactericidal efficiency, easy preparation, and unique mechanism were reported. The grape-like CuTe clusters showed ultra-high sterilization efficacy, especially for Gram-negative bacteria, and effectively inhibited bacterial biofilm development. Reactive oxygen species (ROS) generation and glutathione (GSH) depletion were identified as the synergized mechanisms, and electron microscopy revealed the role of the clusters as bacterial hunters. CuTe significantly reduced bacterial number in a mouse model and increased the mouse survival rate, showing promising application potential.

Summary: This study investigated the hydroxyapatite forming ability, ion release, and antibacterial activity of bioactive glasses with different amounts of strontium oxide and zinc oxide. The results showed that SrO-doped samples had better hydroxyapatite forming ability and the content of hydroxyapatite phase increased with immersion time in modified simulated body fluid. The ion concentration results indicated that the formation of hydroxyapatite was influenced by the comprehensive action of various ions, especially the release rate of Si4+ ions. The antibacterial test showed that the antibacterial activity of the samples was related to the high pH environment and non-physiological concentration of ions in the solution.

Summary: Pesticide residues in fruit and vegetable pose a significant threat to human health. A new method utilizing WPU@AgNPs sticky tapes was developed for rapid extraction and surface-enhanced Raman scattering (SERS) assay of thiabendazole residues on fruit surfaces. The WPU@AgNPs tapes, constructed by coating silver nanoparticles (AgNPs) on waterborne polyurethane (WPU) films, demonstrated excellent sensitivity using 4-Mercaptopyridine (4-Mpy) as the probe molecule. The tapes allowed for easy detection of thiabendazole residues on pear, apple, and banana surfaces, with a detection limit of 1.44, 1.12, and 1.63 ng/cm2, respectively. This strategy could be a common method for rapid, on-site, and ultra-sensitive assay of thiabendazole residues in both chemical and biological fields.

Summary: Trehalose, a non-reducing disaccharide, acts as a protective compound against adverse conditions. The AtTPPI gene in Arabidopsis thaliana is crucial for improving plant water use efficiency and drought tolerance. In this study, we found that AtTPPI also participates in resistance to chilling stress. The expression of AtTPPI is regulated by CBF1, CBF2, and CBF3, and the jasmonic acid signaling pathway genes play a major role in this response. AtTPPI may mediate the synthesis of jasmonic acid and contribute to soluble sugar levels in response to chilling stress.

Summary: Through the chronology study of lacustrine deposits of the Upper Dingqing Formation in the Lunpola Basin, Central Tibet, it has been determined that the geological period is middle Miocene (15-12 Ma). Stable isotope and palynological records indicate a climatic transition around 13.8 Ma, characterized by cooler and drier climate. New palynological elevation reconstructions suggest a maximum paleo-elevation of 3100-3600 m (average 3350 m) for the Lunpola Basin, consistent with floating-leaf plants data. This study provides new insights into paleoenvironmental reconstructions and paleo-elevation estimates of the Lunpola Basin, Central Tibet.

Summary: The effect of solute hydrogen on shear-coupled grain boundary migration was studied and the dual role of hydrogen on grain boundary mobility was revealed. At low temperature and high loading rate, where hydrogen diffusion is slower than grain boundary motion, the grain boundary breaks away from the hydrogen atmosphere and transforms into a new stable phase with enhanced mobility. In the reverse regime, hydrogen atoms move along with the grain boundary, exerting a drag force and decreasing its mobility. These findings provide a rationale for the coexistence of hydrogen hardening and softening observed experimentally in polycrystalline materials.

Summary: Roots are vital for plants in water and nutrient absorption. The phytohormone auxin plays a crucial role in root growth by regulating its synthesis, distribution, and polar transport. The AtTPPI gene from Arabidopsis thaliana improves root architecture and the tppi1 mutant shows shortened primary roots. The mechanism underlying this phenotype, as well as the signaling pathways and genes regulated by AtTPPI, are unclear. Through experiments, it was demonstrated that the AtTPPI gene promotes auxin accumulation in plants and upregulates auxin-related genes. Furthermore, increased AtTPPI expression leads to better primary root growth and lateral root elongation under different nitrate concentrations.

Summary: The complete Gurson model (CGM) with physical void coalescence mechanism is revisited in this study to predict ductile fracture behavior. A method is proposed to determine the effective initial void volume fraction by adopting the cluster nucleation model with an effective initial void volume fraction as the only controlling parameter. The proposed equation has been experimentally verified on three high strength materials and a general procedure for damage parameter identification is suggested.

Summary: Recently, hydrogen-assisted failures have been observed on nickel alloys used in the subsea oil and gas industries. This study investigates the hydrogen diffusion behavior in a nickel Alloy 625 under various pre-strain levels. The results show that while an increase in strain levels reduces hydrogen diffusivity, there is an acceleration in hydrogen diffusion when the strain exceeds a certain level, likely due to hydrogen-enhanced strain-induced vacancy formation at grain boundaries and reduced hydrogen trapping by fractured carbides.

Summary: In this article, high spatiotemporal resolution data obtained by China's APOD satellite are used to study the hemispheric asymmetry of thermospheric density. The results show a strong hemispheric asymmetry of thermospheric atmospheric density response during the magnetic storm, with the atmospheric density in the southern polar region (SPR) on the duskside being higher than that in the northern polar region (NPR). The hemispheric density response asymmetry is related to local time (LT).

Summary: Through analyzing the whole-genome sequences of 795 wheat accessions, it was found that bread wheat originated from the southwest coast of the Caspian Sea and underwent a slow speciation process. It gradually spread across Eurasia in the past few thousand years and formed diversified adaptive landscapes in novel environments. In contrast, the cultivated relatives of bread wheat experienced a population decline due to human food choice shift, and many wheat relatives are predicted to continue shrinking in the future due to climate change. These findings will guide future efforts in protecting and utilizing wheat biodiversity to enhance global wheat production.
