A dual‐layer microencapsulation system composed of alginate, jujube mucilage, and whey protein isolate effectively protected Lacticaseibacillus rhamnosus under heat and simulated gastrointestinal conditions. The optimized formulation (JM:WPI, 6:4) achieved the highest encapsulation efficiency (94.16%).

Tracking Baseflow Supply Dynamics Using SWOT Data From Small Groundwater‐Dominated Lakes
Satellite‐based measurements of groundwater flow‐through kettle lakes efficiently track dynamic groundwater storage at local to regional scales (modified from USGS Scientific Investigations Report 2011–5137). ABSTRACT In situ surface‐water monitoring strategies are biased towards larger perennial streams and lakes and are generally not designed to ...

Gas Hydrates: It's A Gas! [PDF]
In this activity, students will investigate the occurrence of gas hydrates on the ocean floor. They will discover the importance of carbon, where carbon is stored on Earth, and that the largest reservoir of carbon is gas hydrates.

Deep sea cold seeps are a sink for mercury and source for methylmercury
The effect of seafloor cold seeps on the biogeochemical cycling of mercury (Hg) remains enigmatic. Here we demonstrate substantial enrichments of mercury and methylmercury, along with the presence of microbes capable of metabolizing mercury in sediments ...

Microbial Diversity Across Chemolithotrophic and Phototrophic Biofilms in Cold Sulfur Springs
Distinct microbial communities occur between adjacent sulfur‐rich and freshwater springs. Chemolithotrophic and phototrophic sulfur‐oxidizing taxa were enriched in cold sulfur spring biofilms, while adjacent freshwater biofilms supported more diverse microbial community composition.

Abstract During the Eocene‐Oligocene Transition (ca. 34 Ma), the Earth underwent a dramatic decline in atmospheric CO2, global cooling, a deepening of the carbonate compensation depth (CCD), and the formation of a permanent ice sheet on Antarctica. The expansion of Antarctic glaciers eroded the underlying bedrock and increased the weathering flux to ...

Abstract Coastal systems have seen increasing pressure from anthropogenic activities since the beginning of the century, affecting the health of these ecosystems. This increased pressure takes the form of an increase discharge of terrestrial organic matter (OM) and nutrients, leading to a higher primary productivity in the surface waters and to higher ...

Consumption of Methane and CO_2 by Methanotrophic Microbial Mats from Gas Seeps of the Anoxic Black Sea [PDF]
The deep anoxic shelf of the northwestern Black Sea has numerous gas seeps, which are populated by methanotrophic microbial mats in and above the seafloor.
