In Vitro Sperm–Epididymosomes Interaction Immediately Before Fertilization Changes Sperm Fertility Potential

Andrology, EarlyView.
ABSTRACT Background Sperm acquire fertility ability during epididymal maturation mainly in the epididymal caput and corpus, and once matured, are stored in the epididymal cauda. During storage, interactions with cauda epididymosomes (epEVs) may influence sperm fertility potential; however, the role of such interactions on sperm fertility remains ...

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.
