Summary: Electron microscopy provides detailed view of cellular morphology, but lacks applicable pipelines for automatic extraction of comprehensive morphological descriptors. This study presents an unsupervised method to learn cellular morphology from 3D EM data, enabling the exploration of different biological questions in large EM volumes.

Summary: This study utilized metagenomic sequencing datasets to construct MAGs from 30 subtropical estuaries in South China, revealing that these genomes are dominated by taxa assigned to the phylum Proteobacteria, Bacteroidota, and Actinobacteriota. This provides valuable insights into the diversity, phylogenetic history, and metabolic potential of microbiota in estuaries, enhancing our understanding of their structure, function, evolution, and adaptation to extreme conditions in the estuarine ecosystem.

Summary: This study proposes a new physical model for wear prediction in the grinding process, based on the finite element method and numerical simulation technology. Experimental results validate the accuracy of the model. The findings are important for wear prediction and surface quality control in the grinding process.

Summary: This study reports the theoretical and experimental investigation of two polyoxometalate-based metal-organic frameworks (MOFs) as quasi-solid-state electrolytes. The primary ionic conduction mechanism was identified and detailed solvation structures were obtained. Additionally, a noninterpenetrating MOF material with better performance was proposed.

Summary: This study investigates the potential of two polyoxometalate-based metal-organic frameworks as quasi-solid-state electrolytes through theoretical and experimental methods. By simulating diffusion and ionic conduction processes, the primary ionic conduction mechanism is identified and the solvation structure of Li+ motion is obtained. Additionally, a noninterpenetrating material with improved performance is proposed.

Summary: Using a multi-omics approach, this study provides insights into the microbial communities beneath the Ross Ice Shelf in coastal Antarctica. The findings reveal a taxonomically distinct microbial community adapted to a highly oligotrophic marine environment, with aerobic lithoautotrophic archaea and bacteria driving the production of new organic carbon, and aerobic organoheterotrophic bacteria capable of degrading complex organic carbon substrates.

Summary: This study explores the relationship between the nonequilibrium generation of myosin-induced active stress and the pressure-volume relationship of cellular aggregates. It is found that the aggregate surface tension and cell number density depend on size, violating equilibrium assumptions. However, the relationship between them resembles an equilibrium equation of state with an effective temperature.

Summary: The identity and function of a cell type relies on the differential expression of gene batteries. This study uses a multidisciplinary approach to identify the molecular and morphological features of an exocrine, pancreas-like cell type within sea urchin larvae. The researchers found that these cells have unique regulatory wiring and distinct morphological features, suggesting homology with mammalian pancreatic acinar cells. This study contributes to understanding the evolution of cell types and organs.

Summary: This study found a correlation between the volume and morphology of the patella and the volume of the trochlea in trochlear dysplasia, suggesting that patellar volume can be a determining parameter in the evaluation of TD. The technique used in this study can aid in prosthesis construction and more accurate surgical planning.

Summary: In recent years, our understanding of the roles of bacterial communities in the Antarctic Ocean has significantly improved. It has been found that Antarctic marine bacteria are metabolically versatile, and even closely related strains may differ in their functionality and, therefore, affect the ecosystem differently. However, most studies have focused on entire bacterial communities, with little attention given to individual taxonomic groups. This study shows that a 1-degree Celsius increase in water temperature is enough to alter bacterial communities on a short-term temporal scale, emphasizing the importance of understanding how climate change affects bacterial species in the Antarctic.

Summary: This study found that quadriceps muscle volume is positively associated with ACL volume, even after controlling for factors like sex, height, and body mass index. This suggests that ACL size may be modifiable and could potentially be influenced by targeted lower extremity muscle mass development.

Summary: The shape of a cell is important for understanding various cellular processes, but current cell shape descriptors only capture simple geometric features. This study proposes a new framework called FlowShape, which represents cell shape by measuring curvature and mapping it onto a sphere. The framework allows for various shape analyses, including alignment and statistical comparison.

Summary: The study found that environmental factors such as temperature, irradiance, carbonate chemistry, and macronutrient limitation significantly affect the coccosphere, coccolith, and cell volume of the Southern Ocean Emiliania huxleyi ecotype A. There is a strong correlation between cell and coccolith volume, indicating that coccolith volume is primarily controlled by physiological changes in cell volume. Macronutrient limitation, particularly of phosphorus and nitrogen, has the greatest influence on coccolith volume compared to other environmental drivers.

Summary: Deep oligotrophic lakes sustain large populations of Nitrososphaeria, which are the key ammonia oxidizers in this habitat. However, their impact on N-cycling in lakes has rarely been quantified. This study followed the Nitrososphaeria population in Lake Constance and demonstrated their important role in the nitrogen cycle of deep oligotrophic lakes.
