The effects of cell density on low-dose radio-hypersensitivity and increased radioresistance using the minimum mutation load model

This study enhances the Minimum Mutation Load model by incorporating cell density as a key parameter, demonstrating that the extended framework accurately reproduces complex in vitro cell survival curves exhibiting low-dose hyper-radiosensitivity and increased radioresistance with precision comparable to the established Induced Repair model.

Organoid-Derived β-Catenin-Overexpressing Dendritic Cells Alleviate Sepsis- Induced Acute Lung Injury

This study demonstrates that engineering mouse embryonic stem cells to overexpress β-catenin enhances the generation of functional dendritic cells from blood vessel organoids, which effectively alleviate sepsis-induced acute lung injury by restoring pulmonary immune balance and improving survival in a mouse model.

Staphylococcus aureus from Italian red deer carries prophages that harbour the bovine leukocidin lukM/lukF-P83

This study demonstrates that *Staphylococcus aureus* isolates from Italian red deer, belonging to clonal complexes 350 and 425, carry inducible prophages harboring the bovine-specific leukocidin genes *lukM/lukF-P83*, highlighting the potential for these virulence factors to spread among cervids and warranting further investigation into related infections in wild and captive deer populations.

Spectral Signatures Reveal a Transient Commitment Bottleneck During Pancreatic Endocrine Differentiation

This study introduces a physics-inspired spectral framework using singular value decomposition to analyze single-cell transcriptomics data, revealing that murine pancreatic endocrine differentiation involves a transient, low-dimensional commitment bottleneck at the Ngn3-high state followed by asymmetric stabilization of lineage-specific programs.

Beyond Variance: Selecting Low-Rank Temporal Networks That Preserve Causality and Spreading

This paper proposes a process-aware rule for selecting the rank of low-rank temporal network approximations by prioritizing the preservation of causal dynamics like time-respecting reachability and outbreak sizes over traditional variance-based metrics, demonstrating that matrix-optimal compression often fails to capture essential spreading behaviors.

Dopamine Homeostasis Links Age-Dependent Metabolic Stress Resistance to Longevity in Drosophila melanogaster

This study demonstrates that dopamine homeostasis serves as a critical physiological link between age-dependent metabolic stress resistance and longevity in *Drosophila melanogaster*, where elevated dopamine levels enhance starvation tolerance and extend lifespan, while dopamine deficiency has the opposite effect.

Functional profiling of spacecraft cleanroom microbiomes through genome‑wide phenotype predictions

This study presents a genome-based framework combining metagenomics and machine learning to predict survival-relevant microbial traits in spacecraft cleanrooms, demonstrating that functional profiling offers a more accurate risk assessment for icy ocean worlds than traditional taxonomy-based or spore-focused methods.
