Keppel Bay Seabed Sediment Classification Based on Grainsize and Stress

Five distinct seabed sediment classes were identified in Keppel Bay, a macrotidal environment in Central Queensland, Australia. The Australian Ocean Data Network published this dataset, which combines sediment sampling with acoustic seabed mapping tools. Statistical techniques classified sediments based on grainsize, chemical composition, and modelled seabed shear stress from waves and tidal currents.

Genomic Prediction Models for Celiac Disease Risk Across Six European Cohorts

Gad Abraham developed a genomic risk score (GRS) model for celiac disease using statistical learning on genome-wide SNP profiles from six European cohorts. The model achieved cross-validation AUCs of 0.87–0.89 and independent replication AUCs of 0.86–0.9, explaining 30–35% of disease variance. This proof-of-concept demonstrates the potential for genomic-based risk stratification to improve clinical diagnostic pathways.

Palm Oil Metal Concentrations from Bahia, Brazil, Analyzed via FAAS

A study developed a method for determining calcium, magnesium, manganese, iron, and zinc concentrations in palm oil samples using flame atomic absorption spectrometry. The method, optimized via constrained mixture design, was applied to samples collected in Bahia State, Brazil, with reported detection limits between 0.012 and 0.057 mg L-1. Concentrations found in the samples ranged from 3.93-13.9 mg L-1 for Ca, 0.37-2.26 for Mg, >LOQ-0.32 for Mn, 1.77-8.57 for Fe, and 0.38-2.54 for Zn.

Bioaccessibility of Zinc, Calcium, and Phosphorus in Milk and Soybean Samples

250 mL of UHT cow's milk provides approximately 267% of the daily human need for phosphorus, according to in vitro simulated gastric digestion results. This dataset contains total and dialyzed levels of Zn, Ca, and P determined by ICP OES for raw sheep’s milk, soybean extract, raw cow’s milk, UHT goat’s milk, and UHT cow’s milk. Accuracy was verified using a CRM (NIST 8435) and results were statistically evaluated by Student’s t-test.
