Biodegradable metal scaffolds hold great promise for bone repair, yet their clinical translation is hindered by uncontrolled corrosion, rapid ion release, and adverse immune responses, particularly in porous architectures. Here, we report a hybrid scaffold that integrates a cancellous bone-mimicking porous zinc framework with an interpenetrating poly(vinyl alcohol)/TEMPO-oxidized cellulose nanofiber (PVA/TOCN) hydrogel. This design exploits hydroxyl- and carboxyl-mediated chelation of Zn

Oxbow lakes are common features within the agricultural landscape of the Mississippi Alluvial Plain (MAP). Yet it is unclear the role that internal nutrient loads may play in perpetuating eutrophic conditions in shallow MAP lakes. Eight years of depth-integrated water column monitoring in Beasley Lake suggests periods of high benthic PO
