Summary: Exposure to farm environment can both protect from allergic diseases and increase the risk of respiratory syndromes. Proper assessment of cow stable dust characteristics is important before conducting further investigations, and unprocessed stable dust samples can trigger immune responses in studied cell models, suggesting their potential use in investigating asthma-protective mechanisms.

Summary: Dust explosions can occur when the dust exceeds its minimum explosible concentration in the presence of confinement, oxidizer, dispersing agent, and an ignition source. A study was conducted to investigate the dust properties that affect suspension in confined spaces. Dust samples from five grain types were obtained and tested for various characteristics. The results showed significant differences among the grain dust types, and the study contributed to the understanding of grain dust properties and their release into the atmosphere. Quantifying these properties is important for creating better grain handling procedures for improved health and safety.

Summary: NASA is focused on sending humans back to the Moon by 2025 and establishing a sustained presence. The lunar outpost Gateway is a crucial part of this mission, but the impact of microscopic lunar dust particles on its hardware is not well understood. A comprehensive physics-based model is being developed to investigate the interaction between charged lunar dust particles and the spacecraft, using data from experiments and on-orbit measurements.

Summary: This study characterized five different lunar regolith simulants in detail and used the data to create geopolymer concrete samples for testing and analysis. The results showed that these simulant samples are feasible for concrete technology, but their performance varies due to differences in their mineralogy, amorphous content, and particle size and shape distributions.

Summary: This paper proposes an improved calculation method to simulate lunar dust transport during removal by electric curtain-traveling waves in the lunar environment. The research shows that the final dust removal rate is positively correlated with frequency, and negatively related to the surface energy between particles and the film but positively related to applied voltage and particle charge.

Summary: This study elucidated the physicochemical properties and in vivo toxicity of a copper-based herbometallic oxide nanodrug called Thamira parpam (TP). The TP synthesized using a traditional Siddha methodology exhibited nanoscale dimensions and a carbonaceous coating on its surface. In vivo safety testing in rat models showed that TP was non-toxic at a low dose and did not cause abnormalities in major organs and their functions.

Summary: Uniaxial compression tests were conducted on 99.9% pure polycrystalline ������-tin (Sn) at different strain rates and temperatures. The results showed that the strain rate and temperature have significant effects on the stress-strain response, microstructure evolution, and stress relaxation behavior. Neutron diffraction and electron backscatter diffraction were used to characterize the crystallographic structures and deformation mechanisms. Elastic-plastic self-consistent simulations were performed to understand the macroscopic behavior.

Summary: This article presents techniques used to derive the radiometric gain for the VIIRS RSB using unscheduled lunar observations over a range of phase angles. An empirical correction is derived to account for residual phase angle dependencies, successfully applied to estimate the radiometric gain that shows good agreement with gains derived from scheduled lunar events and solar diffuser calibration.

Summary: Recently, accurate diagnosis of thyroid nodules has become crucial, but still faces challenges. Learning-based computer-aided diagnosis systems have gained attention, but there is a lack of research on a deep learning-based system that better aligns with radiologists' decision-making. This study proposes a dual-stream attention neural network, TS-DSANN, that focuses on texture and shape for improved classification performance.

Summary: This study reports isotopic and elemental abundance data for carbonaceous, ordinary, and enstatite chondrite meteorites and explores their variations in relation to other isotopic and elemental data. The study finds that carbonaceous chondrites are susceptible to disturbance in Re/Os ratios and that mineralogical variations and sample size have significant effects on element abundance. The study also expands the existing dataset of Re-Os isotope and HSE abundance measurements.

Summary: Formed in a fire-fountain eruption, the lunar 74220 orange glass beads are capable of recording volcanic plumes on the Moon. They contain high concentrations of volatiles and moderately volatile elements, with a thin and volatile-rich surface coating. The discovery of U-shaped concentration profiles of Na, K, and Cu inside the beads suggests initial outgassing and subsequent in-gassing during their flight through the cooling volcanic gas plume. Modeling based on diffusion and surface equilibrium provides estimates of the cooling time scales of individual beads, ranging from 48 to 179 seconds.

Summary: Collocated crystal sizes and mineral identities are important for understanding geological relationships. Previous Mars rovers were unable to clearly determine these properties. However, the PIXL instrument on the Perseverance rover has shown that diffracted and fluoresced x-rays can provide information about crystalline domains in minerals. Analysis of rocks from the Seitah formation in Jezero crater indicates that they were originally coarsely crystalline igneous phases, with olivine grains partially dissolved and filled with secondary silicate, carbonate, sulfate, and chloride/oxychlorine minerals.

Summary: Diaplectic feldspathic glass, also known as maskelynite, is widely used as an impact indicator for shergottites. The shock conditions of shergottites are crucial for understanding their geochemistry and launch mechanism. However, previous experiments have shown conflicting results regarding the shock pressures required for maskelynitization. This study presents new experimental results that are consistent with the high-pressure minerals found in maskelynitized shergottites.

Summary: Observations of solar system bodies suggest that sodium present in the mineral matrix could potentially sublimate and cause activity on low-perihelion asteroids. Experimental results on carbonaceous chondrite samples indicate that sodium can be released from specific mineral phases under heating conditions similar to Phaethon, supporting the hypothesis of sodium as a volatile element causing activity on these asteroids.
