Molecular Reproduction and Development, Volume 93, Issue 8, August 2026.ABSTRACT cAMP‐dependent protein kinase (PKA) plays a central role in regulating sperm motility in both invertebrates and mammals. The sea mussel Mytilus galloprovincialis provides a valuable model for investigating the molecular mechanisms underlying gamete activation in externally fertilizing organisms.

Unilateral ductus deferens aplasia with terminal cystic dilation in a Bernese mountain dog
Veterinary Record Case Reports, Volume 14, Issue 3, August 2026.Abstract An incidental caudal abdominal mass was discovered in a 5‐year‐old, male, entire Bernese mountain dog. Investigations showed a terminal cystic dilation of the left ductus deferens. Castration, along with surgical resection of the mass, was performed, and histopathology of the mass and ductus deferens was consistent with segmental aplasia of ...

Elevated LncRNA LINC00966 Suppresses PDE2A to Impair Sperm Motility in Asthenozoospermia
FASEB BioAdvances, Volume 8, Issue 8, August 2026.This study identifies LINC00966 as an upregulated lncRNA in asthenozoospermia associated with reduced sperm quality. Linc00966 suppresses Pde2a, disrupts cGMP signaling, and promotes oxidative stress, thereby impairing spermatogenic cell viability and migration.

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.Though drive efficiency was highly influential to model outcomes, such parameters will likely be known prior to any experimental gene drive introductions. We conclude that understanding the ecological and life‐history characteristics specific to target populations will be critical to accurately predict gene drive outcomes and inform risk assessments ...

Australian Journal of Rural Health, Volume 34, Issue 4, August 2026.ABSTRACT Objective Women in rural and remote Queensland face greater challenges in accessing fertility care than those residing in large regional or metropolitan centres of Australia. This study aims to explore the experiences of women accessing fertility care while living in a rural or remote area of Queensland and their perspectives on ways to ...

Development, Growth &Differentiation, Volume 68, Issue 6, August 2026.ABSTRACT The RNA‐binding protein NANOS2 plays a crucial role in male gonocyte development and the maintenance of spermatogonial stem cells. In the absence of the Nanos2 gene (Nanos2‐KO), germ cells fail to enter G0 arrest and initiate the male differentiation program (including DNA methylation and the piRNA pathway), ultimately undergoing apoptosis ...

Entomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 842-850, August 2026.Nymphal development took longer at 25°C than 30°C, and the Greek N. tenuis population developed more slowly than the commercial population. Nymphs clearly preferred E. kuehniella eggs over Artemia sp. cysts when both were offered equally. Egg production increased at 30°C, while female longevity declined.
