Fecal pellet packaging enhances marine carbon sequestration

open access: yesLimnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Fecal pellets produced by marine zooplankton contribute substantially to transporting biologically fixed carbon from the sunlit sea surface into deeper water layers. Their occurrence and composition are often heterogeneous, and pellets may undergo various changes while sinking, making it difficult to quantitatively assess their mechanisms of ...

Engineering Nanocellulose Scaffolds: Property Modification Strategies and Mechanotransduction‐Driven Tissue Outcomes

open access: yesPolymers for Advanced Technologies, Volume 37, Issue 3, March 2026.
ABSTRACT Nanocellulose is being increasingly used in biomedical applications because of its biocompatibility, mechanical robustness, tunable surface chemistry, and adjustable rheology. This review evaluates recent strategies for engineering cellulose nanofibrils, nanocrystals, and bacterial nanocellulose into cell‐instructive scaffolds for skin, bone ...

Assessment of Bottom Trawl Impacts on the Status of Seabed Communities in European Seas

open access: yesFish and Fisheries, Volume 27, Issue 2, Page 285-299, March 2026.
ABSTRACT Bottom trawling affects seabed habitats, but its large‐scale impacts remain poorly quantified. Assessment of trawling impacts is essential to support monitoring and achieving sustainability objectives under international conventions, sustainable development goals, and seafood certification programs.
