Determination of Virus Abundance in Marine Sediments [PDF]
Applied and Environmental Microbiology, 2001 ABSTRACT In this study, we optimized procedures to enumerate viruses from marine sediments by epifluorescence microscopy using SYBR Green I as a stain. The highest virus yields from the bulk of the sediments were obtained by utilizing pyrophosphate and 3 min of sonication.

Marine sediments tell it like it was [PDF]
Proceedings of the National Academy of Sciences, 2007 We live in a constantly changing environment. Although some changes are natural and therefore beyond our control, there is no question that many anthropogenic activities have dramatically altered our planet. The “human footprint” is now discernable around the globe, so much so that Crutzen (1) proposed a new geological epoch (the Anthropocene) to ...

Reactive iron in marine sediments [PDF]
Geochimica et Cosmochimica Acta, 1989 A combined field/laboratory study has been undertaken to explore the mineralogy, concentrations and reactivity (towards sulfide) of iron in marine sediments. Also considered is the importance of bacterial Fe liberation in regulating pore-water chemistry. Two contrasting marine environments are included; one is the relatively Fe-poor FOAM site and the

Magnetotactic symbiosis in marine sediments [PDF]
Nature Reviews Microbiology, 2019 This study reports a mutualistic symbiosis between excavate protists and ectosymbiotic Deltaproteobacteria in anoxic marine sediments, revealing a unique example of eukaryotic magnetoreception acquired by symbiosis.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Advanced Engineering Materials, EarlyView.This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.
