Supergene associated with ant queen wing polymorphism and its evolutionary history in Myrmecina nipponica

This study identifies a large-scale supergene, characterized by a 1.75 Mbp inversion and translocation, that governs wing polymorphism in *Myrmecina nipponica* queens and likely evolved within and among *Myrmecina* species to mediate caste determination through transcriptional regulation of nutritional responses.

Heterochronic Expression of TFAP2β in Coarctation of the Aorta

This study identifies a heterochronic expression pattern of TFAP2β, revealing that while its protein levels normally decline by term in mammalian models, they persist postnatally specifically within the obstructive shelf of coarctation of the aorta, offering a potential mechanistic insight into this congenital heart defect.

Genetic susceptibility to anterior cruciate ligament rupture in athletes: a genome-wide association case–control study

This genome-wide association study of 607 athletes of European ancestry failed to identify genome-wide significant genetic variants for anterior cruciate ligament rupture but highlighted several suggestive loci involved in inflammation, cellular stress, and ciliary function that warrant further investigation in larger cohorts.

Single-cell and pseudobulk transcriptomic profiling reveals immune-enriched disease- associated signatures in human pancreatic islets from type 2 diabetes

This study reanalyzes single-cell transcriptomic data from human pancreatic islets to demonstrate that type 2 diabetes-associated signatures are subtle and compartment-specific, with immune-enriched signals like CXCL3 being best detected through donor-aware pseudobulk analysis rather than global or cell-level approaches.

Engineered Salmonella expressing IL-18 as a therapeutic strategy for colorectal cancer

This study demonstrates that attenuated *Salmonella* Typhimurium engineered to express bioactive interleukin-18 exerts potent antitumor effects against colorectal cancer by significantly reducing tumor cell viability and shifting the tumor microenvironment toward a pro-inflammatory, antitumor state.

The CYP6P4 I236M Mutation Imposes High Fitness Costs and Increases Susceptibility to Chlorfenapyr-Based Insecticide-Treated Nets in Anopheles gambiae

This study demonstrates that while the CYP6P4-I236M mutation in *Anopheles gambiae* confers strong resistance to pyrethroid and PBO-based nets, it imposes significant fitness costs and reduced efficacy against chlorfenapyr-based nets, suggesting that rotation or mixture strategies with chlorfenapyr could effectively manage resistance.

The bigfin reef squid (Sepioteuthis lessoniana Férussac, 1831) species complex in the Mediterranean Sea: genetic evidence for multiple Red Sea lineages in a Lessepsian migrant

This study reveals that the bigfin reef squid in the Mediterranean Sea comprises at least two distinct cryptic lineages of Red Sea origin, challenging the traditional view of *Sepioteuthis lessoniana* as a single species and highlighting the complexity of Lessepsian invasions.

CRISPR/Cas12a-based method to discriminate Plasmodium ovale wallikeri and Plasmodium ovale curtisi

This study developed and validated a highly specific and sensitive CRISPR/Cas12a-based detection system capable of accurately discriminating between the two genetically distinct *Plasmodium ovale* species (*P. wallikeri* and *P. curtisi*) in clinical samples, offering a promising tool for improved malaria diagnosis and surveillance.

Diversity, Nesting Ecology and Worker-level Morphometric Structure of Stingless Bees (Hymenoptera: Apidae: Meliponini) in the Bimodal Forest Zone of Central Cameroon

This study documents the diversity, nesting ecology, and worker-level morphometric structure of stingless bees in Central Cameroon's bimodal forest zone, revealing that *Hypotrigona gribodoi* and *Dactylurina staudingeri* exhibit contrasting, size-structured phenotypic variations and distinct nesting habits while establishing the first locality-resolved baseline to support conservation and meliponiculture.
