Lactoferrin protein (LF) is a natural protein with certain emulsifying ability, but is sensitive to be affected by environmental factors and has poor oxidative stability to be used as emulsifier. In this study, the emulsifying ability of LF was significantly improved after conjugation with Rosa roxburghii Tratt fruit polysaccharides (RTFP), and the emulsion stability mechanism of LF-RTFP conjugates (L-R) were elucidated through the utilization of CLSM (confocal laser scanning microscopy), interfacial tension, apparent viscosity, and protein adsorption rate. The emulsion stabilized by L-R showed the smaller particle size (17.

Polar marine macroalgae thrive in extreme conditions, often displaying geographic isolation and high degree of endemism. The "phycosphere" refers to the zone around the algae inhabited by microrganisms. Our study used DNA metabarcoding to survey the eukaryotic communities associated with seven seaweed species obtained at King George Island (South Shetland Islands, maritime Antarctic), including two Rhodophyta, two Chlorophyta and three Phaeophyceae.

Background: Climate change has severe health impacts, particularly for populations living in environmentally sensitive areas such as riversides, slopes, and forests. These challenges are exacerbated for Indigenous communities, who often face marginalisation and rely heavily on the land for their livelihoods. Despite their vulnerability, the perspectives of Indigenous populations on climate change and its impacts remain underexplored, creating a critical gap in the literature.

The click beetles (Elateridae) represent the major and well-known group of the polyphagan superfamily Elateroidea. Despite a relatively rich fossil record of Mesozoic Elateridae, only a few species are described from the Upper Cretaceous Burmese amber. Although Elateridae spend most of their lives as larvae, our knowledge on immature stages of this family is limited, which is especially valid for the fossils.

This study presents the fabrication and characterization of mixed matrix membranes (MMMs) incorporating green-synthesized silver nanoparticles (AgNPs) using Hibiscus Rosa sinensis extract within a polyethersulfone (PES) matrix for nanofiltration (NF) application. The membranes were evaluated for their pure water permeability, salt rejection, dye removal, and antifouling performance. Results showed that the membrane with 0.
