Summary: This study presents methods for assessing the health quality of products containing betalains, comparing data on phytochemical composition of beetroot cultivars using various techniques. Identified that betalain contributes about 50% to the antioxidant activity in red beetroot. Photometric measurements are recommended for simple analysis of betacyanin and betaxanthin content, while liquid chromatography techniques provide more precise information. The combination of liquid chromatography with high-resolution mass spectrometry is recommended for more detailed metabolomics studies, identifying sixty-four phytochemicals in beetroot samples.

Summary: Iridescence is found in a wide range of organisms, with birds displaying a variety of iridescent structural colors in their feathers. The development of iridescent and non-iridescent feathers in superb starlings involves differences in the arrangement and composition of melanosomes, and gene expression related to pigmentation, metabolism, and cellular organization. Iridescent feathers may form through a combination of passive self-assembly and active processes involving gene expression.

Summary: Micro-Raman spectroscopy was used to analyze samples from shelters in Piedra Parada valley, Chubut province, Argentinian Patagonia, revealing the composition of colored layers and degradation products, as well as the impact of materials on rock paintings and support. The study positively identified minerals like haematite, goethite, and gypsum in the painted layers, and silicates, apatite, and goethite in the rock support. Point analysis and micro-Raman mappings provided a better understanding of the materials and layer sequencing in the samples.

Summary: The study investigates the mechanisms of metallic coloration in springtails, revealing that the broadband metallic color is produced through the collaboration of longitudinal ridges with thin-film effects. Spatial color mixing is observed in the production of broadband coloration, likely resulting from nanoscale variations in scale thickness and ridge height and distance.
