Summary: In this study, X-ray interferometer-based phase-contrast computed tomography was used for the nondestructive observation of precooked rice products. The phase-contrast images successfully captured the internal structure of cooked rice grains, while X-ray absorption images were unable to distinguish the grains.

Summary: Behaviors are integral to the daily lives of human beings, vertebrates, and to some extent, invertebrates, and can be studied through the concepts of behavioral ecology. Despite the minimal commonalities between humans and fungi, fungi also exhibit behaviors that can be better understood through the lens of behavioral ecology. Insights from fungal behavior may contribute to a broader understanding of behavioral ecology as a whole.

Summary: The complex sequences of paleosols in the NW slope of Mt. Cusna have been studied to reconstruct past environmental conditions and climate shifts, revealing distinct pedological units associated with different stability phases along the slope. This multidisciplinary study sheds light on the polygenesis of soils and the succession of stability phases and erosion/deposition processes in the area.

Summary: The formation and distribution of substrate is crucial for understanding soil evolution in Mediterranean hillslope environments, and existing soil evolution models cannot provide plausible explanations. This study investigates a limestone hillslope in western Portugal to recover information on soil substrate layering and proposes a fully substrate-genetic, allochthonous soil evolution model.

Summary: This study critically evaluates the impact of pretreatment methods on the chemical compositions of modern soils and their implications for estimating mean annual precipitation using two commonly employed climofunction indices. The research finds that acid digestion pretreatment significantly depletes calcium oxide and leads to substantial overestimation of precipitation estimates. The extent of overestimation is correlated with the calcium carbonate content of the soil material. This has important implications for the appropriate application of these indices as proxies for paleoprecipitation estimates from paleosol profiles containing carbonates.

Summary: Plaggic Anthrosol, artificially created fertile soils, serve as an archive chronicling the paleoecological and paleogeographical history of mankind. They have been discovered in Western Europe and North Asia, and are similar to Terric Anthrosols found in southwestern Pacific and South America. This article discusses the geographical distribution, genesis, key properties, and carbon stabilization mechanisms of Plaggic Anthrosol, emphasizing their potential for sustainable carbon sequestration and soil fertility enhancement.

Summary: Understanding the dynamics of soil moisture memory (SMM) is crucial, with soil texture playing a key role and organic matter content showing a strong relationship with the stored precipitation fraction (F-p). The study highlights the importance of precise characterization of water storage conditions, especially in terms of texture and organic matter content, in understanding SMM dynamics.

Summary: This study explored the factors influencing soil mass failure in hollows through experimental methods and found that initial moisture content, slope angle, and clay content have significant effects on soil mass collapse. The study also provides a detailed insight into the processes and factors involved in soil mass failure, which can be utilized to improve monitoring, early warning, and forecasting systems.

Summary: After over 8 years of successful surface operations on Mars, the Curiosity rover has revealed much about the environment in Gale crater. Most of the deposits in Gale crater seemingly did not form in an ancient lake, but were instead formed by eolian and/or volcaniclastic sediments subaerially chemically weathered by acidic precipitation in a reduced atmosphere. Despite not forming in an ancient lake, the results shed considerable light on ancient climate, environmental change, and the astrobiology of Mars.

Summary: The Guijiatun Formation in the Early Devonian period in Qujing, Yunnan, South China represents a dryland river system that contains abundant plant traces and calcareous paleosols, providing direct evidence for the development of primitive vegetation on drylands. These findings indicate that dryland floras were significant in the Early Devonian landscapes.

Summary: Desiccation cracking is a common phenomenon in purple soil subjected to rainfall-evaporation cycles, which affects the hydraulic and mechanical properties of the soil. The variability in aggregate size distribution leads to variations in crack morphology. In this study, the effects of aggregate size distribution on crack morphology were investigated, and regression analysis based on purple soil indices was conducted. The results showed that crack evolution in purple soil involves three stages, two intersection shapes, and three network forms. A cracking evolution function was proposed, and its fit for modeling the dynamic morphological characteristics of desiccation cracks was verified. The distribution of crack length, crack area, and clod area were well described, while crack width followed a bimodal Gaussian distribution. Multiple linear regression models between crack parameters and aggregate size distribution indices were established, indicating the significant effect of micro-aggregate state on crack morphology.

Summary: Original vertical joints (OVJs) have been considered a non-tectonic source of erosion and landform fragmentation in loess regions, but the current literature lacks a systematic overview of their origin. By reviewing key factors governing the formation and evolution of OVJs, a conceptual framework and case study demonstrate their genesis and dynamics. This new perspective enhances theoretical understanding of anisotropy formation and structural evolution in loess, aiding in modeling subsurface hydrology and geohazard risks in these regions.

Summary: This study used carbon isotope analysis to reconstruct bioclimatic change in buried soils from the central Great Plains of North America. The results revealed a paradoxical isotopic disequilibrium between the isotopic composition of soil organic matter (SOM) and pedogenic carbonate. Multiple hypotheses were proposed to explain this discrepancy, including climate, vegetation, parent material, and time. Overall, this study highlights the importance of assessing pedogenic carbonates for isotopic equilibrium and understanding past environmental conditions.

Summary: A study examined the durability and breadth of serum-neutralizing antibody responses against different SARS-CoV-2 variants after receiving the original COVID-19 mRNA vaccine. The decay half-lives of WA1 and Delta-nAbs were found to be approximately 60 days after the second and third vaccine doses. Surprisingly, the serum antibodies neutralizing three different Omicron subvariants showed much better durability with a half-life of >= 6 months. Furthermore, booster doses of the original COVID-19 vaccine were found to broaden antibody responses against multiple sarbecoviruses, suggesting potential protection against future spillover from animal reservoirs.
