Altered by Gold: A Comparative Zooarchaeological Analysis of 19th to 20th Century Chinese and British Migrants in Ravenswood, a Northern Queensland Gold Mining Town

Archaeology in Oceania, Volume 61, Issue 2, Page 312-333, July 2026.
ABSTRACT Gold discoveries transformed the 19th century British colony of Queensland, Australia, driving migration, a second wave of pastoral expansion northwards, and an increasingly diverse population. This study presents a comparative and contextual zooarchaeological analysis of British and southern Chinese food waste—globally significant migrant ...

Genetic Control of Tissue Remodeling by a Non‐Coding SNP in ITGA8 Explains Carotenoid‐Based Color Polymorphism in Marine Mollusks

Advanced Science, Volume 13, Issue 27, 13 May 2026.
In this study, the orange‐muscle giant abalone (Haliotis gigantea) is used as a model to identify a non‐coding SNP that disrupts the interaction between ITGA8 pre‐mRNA and the splicing factor ILF2, leading to altered ITGA8 splicing. These splicing changes promote carotenoid accumulation in abalone muscle through the regulation of tissue remodeling ...

Crustacean and Mollusc Shell Proteins: Origin, Structure, and Functionality

Journal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT Crustacean and molluscan processing as seafood generates a significant amount of shell waste annually, owing to the dense, mineral‐rich composition of the exoskeleton. Although valorization efforts have mostly focused on chitin and chitosan, the protein fraction remains underutilized despite its prominent nutritional, functional, and sensory ...

Methods for Improving Settlement and Metamorphosis of Shelled Marine Mollusks in Aquaculture: A Review

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Settlement and metamorphosis are key developmental hurdles in marine mollusk aquaculture. Environmental signals (such as biofilms, algae, and signals from conspecifics) and biochemical pathways (including nitric oxide, thyroid hormones, catecholamines, and GABA) regulate the transition of larvae into benthic juveniles. Combining ecological observations

Assessment of Pinctada radiata extract effect in preventing cisplatin-induced kidney damage: biochemical, histopathological, and immunohistochemical evidence

Journal of Basic and Applied Zoology
Background Cisplatin (CIS) is an effective cancer therapy, but its nephrotoxicity often causes acute kidney injury, hence restricting its usage. This study assessed the nephroprotective effects of Pinctada radiata lipid extract (PRE) against cisplatin ...
