Multiple spermatophore transfer during prolonged mating in the apterous Neotropical cricket Unacla meridionalis (Desutter-Grandcolas, 1994) (Orthoptera: Grylloidea: Phalangopsidae)

This study documents the mating behavior of the apterous cricket *Unacla meridionalis*, revealing a prolonged two-hour copulation involving multiple spermatophore transfers and a unique post-copulatory pattern where females consume the spermatophores, suggesting a post-nuptial gift that contrasts with typical male consumption in related species.

Interplay between actin cytoskeleton and mitochondrial remodeling in endothelial cells stimulated with malaria patient sera

This study demonstrates that proinflammatory cytokines in severe malaria patient sera induce endothelial cell dysfunction by coordinately disrupting the actin cytoskeleton and promoting mitochondrial fragmentation, thereby elucidating a key mechanism in malaria pathogenesis.

Fractal Scaling in Music and EEG Dynamics‎: ‎A Detrended Fluctuation Analysis Study

This study utilizes Detrended Fluctuation Analysis to demonstrate a strong correspondence between the fractal scaling properties of musical features (Pitch, Loudness, and Rhythm) and the distinct, scale-dependent neural responses observed in EEG signals, where calming music enhances long-range temporal correlations in slow brain waves while stimulating music promotes faster, less persistent activity in higher frequency bands.

Evaluation of human-specific RNA enrichment kits for transcriptome sequencing in a non-model organism: the African savanna elephant (Loxodonta africana)

This study demonstrates that human-specific RNA enrichment kits effectively deplete ribosomal RNA and significantly improve genome alignment efficiency in African savanna elephant whole blood samples, thereby establishing an optimized workflow for downstream transcriptomic analysis of immune responses in this non-model species.

Characterization of Porcine Parvovirus 6 detected in domestic pig in Nigeria using Metagenomic Sequencing, Immuno-informatics and Capsid Structure Modeling

This study reports the first detection and comprehensive characterization of a highly divergent Porcine Parvovirus 6 variant (NGRA4) in Nigeria, revealing its ancestral phylogenetic position, unique capsid structural features, and evidence of immune-driven evolution that underscores the need for enhanced surveillance of PPV6 in African swine populations.

LiteVax-adjuvanted influenza vaccine induces transient interferon-driven innate activation and accelerates early IgG3 responses in older adults

This study demonstrates that the LiteVax adjuvant enhances influenza vaccine immunogenicity in older adults by inducing a transient, monocyte-driven interferon response that accelerates early IgG3 production and improves T-cell memory differentiation, thereby mitigating age-related immune decline.

Evaluating Predicted Coral Heat Stress Phenotypes and Microbial Associations in Nursery- Propagated Corals During a Real-World Bleaching Event

This study demonstrates that while acute heat stress assays can predict coral thermotolerance, the real-world bleaching performance of nursery-propagated corals during the 2024 mass bleaching event is critically dependent on environmental context and species identity rather than microbial associations.
