Polyphenols alter κ-carrageenan gel mechanics, adhesion, and disintegration
What the study found Plant-derived polyphenols can reprogram kappa-carrageenan (κ-CRG, a seaweed-derived polysaccharide used to form hydrogels) in a structure-dependent way. The authors report that this changes gel mechanics, thermal behavior, adhesion, and how the gels break down in water-based fluids. Why the authors say this matters The authors conclude that this provides a fully…
DNA barcoding found mixed genetic patterns in alien Volga-Kama fish
—
in ZoologyDNA barcoding of non-indigenous fish in the Volga-Kama basin reveals genetic structures reflecting dispersal histories and questions current taxonomic classifications.
Phosphate shortage limits bacterial fucoidan breakdown
—
in MicrobiologyPhosphate deprivation inhibits bacterial degradation of fucoidan, a marine polysaccharide, potentially enhancing carbon sequestration in oceanic systems and extending dissolved organic matter.
Bill-fish taxonomy and angling potential in South and East Africa
Survey of billfishes in the tropical Western Indian Ocean documents high abundance, persistent taxonomic and life-history gaps for marlins, and calls for focused ontogenetic and systematic research.
