New seismic imaging from the Mussau Trench confirms that, under horizontal compression on an oceanic plate boundary, it is within the young and weak oceanic plate that a trench will develop, and it is the young plate, not so long after its birth, that starts to subduct toward the old plate. The Mesozoic Pacific Plate cannot easily bend, under the joint horizontal compression and vertical gravity pull, even with a pre-existing weak zone in place and with a large age offset across the plate boundary. The bending of the Caroline Plate near the northern end of the Mussau Trench started only after a long-time span of trench migration, and/or after a prolonged transition from initial compression to trench development. Highly contrasting trench deformation and sedimentary accretion between two parallel seismic sections support an evident migration of underthrusting or significant longitudinal heterogeneity along the trench. The swift transition from underthrusting to non-thrusting can be explained by a counter-clockwise rotation of the Caroline Plate. That miniature accretionary wedges develop even before the subduction initiates imply strong compression and uplifting before the underthrusting can kick-start. Rotation of the Caroline Plate have been halted as the Mussau Trench is seismically rather quiet and the Lyra Trough to the east shows relaxational extension.

Cells are the fundamental units of biological systems and exhibit unique development trajectories and molecular features. Our exploration of how the genomes orchestrate the formation and maintenance of each cell, and control the cellular phenotypes of various organismsis, is both captivating and intricate. Since the inception of the first single-cell RNA technology, technologies related to single-cell sequencing have experienced rapid advancements in recent years. These technologies have expanded horizontally to include single-cell genome, epigenome,proteome, and metabolome, while vertically, they have progressed to integrate multiple omics data and incorporate additional information such as spatial sc RNA-seq and CRISPR screening. Single-cell omics represent a groundbreaking advancement in the biomedical field,offering profound insights into the understanding of complex diseases, including cancers. Here, we comprehensively summarize recent advances in single-cell omics technologies, with a specific focus on the methodology section. This overview aims to guide researchers in selecting appropriate methods for single-cell sequencing and related data analysis.

Altered rock， often encountered in major engineering projects， can seriously affect the stability of rocks and slopes surrounding deeply buried tunnels. This study addressed the alteration mechanism， alteration degree classification， and mechanical parameters of altered rock in engineering project areas using field testing， thin slice identification， X-ray diffraction， and major element testing. Results showed that the altered rock types in the areas of the Pingjiang Pumped Storage Power Station (Hunan Province) and a diversion tunnel in northern Xinjiang include biotite granodiorite， biotite monzogranite， and cataclastic granite， and that the main alteration mechanisms are chloritization of biotite and clayization of feldspar minerals. The altered rocks were classified as slightly， moderately， or strongly altered according to their apparent characteristics， rebound value， longitudinal wave velocity， metamorphic mineral content， and porosity. The bulk density， elastic modulus， cohesion， and internal friction angle (Poisson’s ratio) of the altered rocks decreased (increased) with increase in the degree of alteration. Numerical simulations showed that in altered rock slope areas， the zone of strong rock alteration and the moderate–strong alteration contact zone exhibit locally large deformations that represent certain hazard to engineering projects. These results provide valuable guidance and support for major projects in altered rock areas.

Electron shuttles are widespread in the environments and play important role in microbe-mineral interaction. This study investigated the effects of a model electron shuttle (i.e.， anthraquinone-2， 6-disulfonate， AQDS) on Shewanella oneidensis MR-1-mediated Fenton reaction and subsequent degradation of 2， 2′， 4， 4′-tetrabrominated diphenyl ether (BDE-47). Three Fe(III)-containing minerals， namely， ferrihydrite， goethite and nontronite， were used as electron acceptors and Fe(II) sources. With each mineral， additions of 0.01 – 1 mM AQDS in the reactions significantly enhanced Fe(III) reduction by S. oneidensis MR-1 and increased the amounts of Fe(II) produced in anoxic phase. As a result， the amounts of cumulative ·OH formed in oxic phase were increased by 10% – 287%. Regression analysis revealed that ·OH cumulation has significant linear correlation with sorbed Fe(II) but not aqueous and structural Fe(II). This finding may be ascribed to the higher reactivity of sorbed Fe(II) in oxygenation than the latter two types of Fe(II). With more ·OH， the degradation efficiency of BDE-47 was elevated by 31% – 173%. Collectively， AQDS enhances ·OH formation and BDE-47 degradation by promoting production of Fe(II)， particularly sorbed Fe(II) in S. oneidensis MR-1-mediated Fenton reaction with Fe(III)-containing minerals.
