7000 Years of Aboriginal Mining at Sugarloaf Hill in the Riverland Region of South Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Silcrete and chert are commonly represented in Aboriginal archaeological lithic assemblages across large parts of the southwestern Murray‐Darling Basin (MDB). In South Australia (SA), these materials were sourced from a series of quarries located along the incised course of the Murray River through the upper Riverland region.

The impact of family interview on the relationship between medical students and their silent mentor

Anatomical Sciences Education, EarlyView.
Abstract The gross anatomy laboratory course often triggers significant negative emotions in medical students during dissection. While various pedagogical interventions aim to alleviate psychological burden, the fundamental question of how students' perceptions of donors evolve throughout the course remains underexplored.

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Emerging research directions in nanoparticle‐based foam control for bioprocessing: a bibliometric approach

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Overfoaming remains a critical challenge in industrial bioprocesses, compromising mass transfer, operational stability, and downstream efficiency in bioreactors and wastewater treatment systems. This study provides a bibliometric and scientometric assessment of nanoparticle‐enabled foam control to map technological trends and identify research
