Sexual Behavior and Reproductive Investment in the Sapotaceae-Associated Fruit Fly Anastrepha dentata (Diptera: Tephritidae) Across Contrasting Environmental Conditions

This study provides the first detailed description of the reproductive biology of *Anastrepha dentata*, revealing that this Sapotaceae-associated fruit fly exhibits exceptionally delayed sexual maturation, complex multimodal courtship behaviors including lek formation, and unusually long copulation durations across contrasting environmental conditions in central Veracruz, Mexico.

Rapid host species identification from dried bloodspots of Culex mosquito blood meals using Mid-Infrared Spectroscopy

This study demonstrates that mid-infrared spectroscopy combined with machine learning can rapidly and cost-effectively identify host species from dried blood meals of *Culex* mosquitoes, offering a scalable alternative to traditional methods for vector-borne disease surveillance, particularly in low-resource settings.

Geometry-Aware Abdominal Aortic Aneurysm Digital Twin for Patient-Specific Wall Stress Mapping

This paper presents a graph-based deep learning framework, specifically utilizing a Graph Transformer, that rapidly and accurately predicts patient-specific abdominal aortic aneurysm wall stress distributions from CTA-derived meshes, reducing inference time from hours to seconds while maintaining high fidelity to traditional finite element analysis.

Sequentially Self-Assembled Supramolecular Nanocomplexes Enable Systemic Cas9 RNP Delivery and In Vivo Tumor Genome Editing

This study reports a sequentially self-assembled supramolecular ternary complex that enables systemic delivery of Cas9 ribonucleoproteins to tumors, achieving efficient in vivo genome editing and significant tumor growth suppression by overcoming rapid clearance and enabling selective endosomal release.

Long-term curling training reshapes region-specific patterns of prefrontal cortex resting-state activity: an expert–beginner comparison based on fNIRS

This study demonstrates that long-term curling training induces a region-specific redistribution of resting-state prefrontal cortex activity in athletes compared to novices, characterized by decreased activity in planning regions, increased activity in decision-making and control regions, and a positive correlation between training duration and inhibition-related neural activity, thereby highlighting how strategic, low-load sports reshape the brain's functional organization.

The theory of Janzen-Connell effects in corals: How dispersal and clonal growth shape pathogen-mediated coexistence

This study utilizes a lattice model to demonstrate that while long-distance coral larval dispersal and global pathogen dispersal generally promote species coexistence by mitigating Janzen-Connell effects, the specific outcome in coral communities depends on complex interactions involving clonal growth, pathogen specificity, and size-dependent demographic rates.

Longitudinal evaluation of primary uterine leiomyoma cells reveals culture-dependent shifts in molecular identity and drug responsiveness

This study demonstrates that primary uterine leiomyoma cells rapidly lose their native molecular identity and drug responsiveness during standard 2D culture, necessitating the use of early-passage cells to ensure the reliability and translational relevance of in vitro pharmacological evaluations.

Attention-Augmented Genomic Prediction of Sheep Fecundity Across Breed Boundaries: A Breed-Shared Signal From Longitudinal Phenotypes

This study demonstrates that by integrating longitudinal fertility records, cross-breed modeling, and dimensionality-reduced SNP panels, attention-augmented genomic architectures can achieve high-accuracy discrimination between high- and low-fecundity sheep across breed boundaries, enabling early-life selection for prolificacy.
