Common reef-building coral in the Northern Red Sea resistant to elevated temperature and acidification

Julia Marie Jeanne Yvonne Bodin, Anders Meibom, Stéphane Laurent Escrig, Maria-Evangelia Giovani, Thomas Krüger, Maoz Fine

Coral reefs are currently experiencing substantial ecological impoverishment as a result of anthropogenic stressors, and the majority of reefs are facing immediate risk. Increasing ocean surface temperatures induce frequent coral mass bleaching events—the ...

Weekly to monthly time scale of melt inclusion entrapment prior to eruption recorded by phosphorus distribution in olivine from mid-ocean ridges

Lukas Baumgartner, Mélina Manzini, Anders Meibom, Stéphane Laurent Escrig, Othmar Müntener

Melt inclusions (MIs) hosted in euhedral olivine have been proposed to represent droplets of primary melt, protected from processes occurring near Earth's surface during eruption. The complex zoning of phosphorus (P) in some olivines and the presence of a ...

The importance of mantle wedge heterogeneity to subduction zone magmatism and the origin of EM1

Stéphane Laurent Escrig

The composition of the convecting asthenospheric mantle that feeds the mantle wedge can be investigated via rear-arc lavas that have minimal slab influence. This "ambient mantle wedge" composition (the composition of the wedge prior to the addition of a sl ...

Short magmatic residence times of quartz phenocrysts in Patagonian rhyolites associated with Gondwana breakup

Lukas Baumgartner, Anders Meibom, Stéphane Laurent Escrig, Susanne Seitz

A key parameter in the study of magma evolution is the time scale on which magmatic processes occur. Using nanoscale secondary ion mass spectrometry (NanoSIMS), SIMS, and cathodoluminescence (CL) analyses, we have measured titanium (Ti) diffusion profiles ...

En route to ion microprobe analysis of soluble compounds at single cell level: The CryoNanoSIMS

Arnaud Comment, Tian Cheng, Anders Meibom, Stéphane Laurent Escrig, Florent Olivier Vivien Plane, Louise Helene Soegaard Jensen

Phenotypic heterogeneity driven by nutrient limitation promotes growth in fluctuating environments

Anders Meibom, Stéphane Laurent Escrig, Martin Ackermann

Most microorganisms live in environments where nutrients are limited and fluctuate over time. Cells respond to nutrient fluctuations by sensing and adapting their physiological state. Recent studies suggest phenotypic heterogeneity(1) in isogenic populatio ...

Parental arc magma compositions dominantly controlled by mantle-wedge thermal structure

Stéphane Laurent Escrig

The processes that lead to the fourfold variation in arc-averaged compositions of mafic arc iavas remain controversial. Control by the mantle-wedge thermal structure is supported by chemical correlations with the thickness of the underlying arc crust(1-3), ...

Aragonitic scleractinian corals in the Cretaceous calcitic sea

Anders Meibom, Stéphane Laurent Escrig, Jaroslaw Hubert Stolarski

Changes in seawater chemistry have affected the evolution of calcifying marine organisms, including their skeletal polymorph (calcite versus aragonite), which is believed to have been strongly influenced by the Mg/Ca ratio at the time these animals first e ...

Imaging the time-integrated cerebral metabolic activity with subcellular resolution through nanometer-scale detection of biosynthetic products deriving from (13)C-glucose

Arnaud Comment, Graham Knott, Yuhei Takado, Anders Meibom, Stéphane Laurent Escrig, Mojgan Masoodi

Glucose is the primary source of energy for the brain but also an important source of building blocks for proteins, lipids, and nucleic acids. Little is known about the use of glucose for biosynthesis in tissues at the cellular level. We demonstrate that l ...

Imaging liver and brain glycogen metabolism at the nanometer scale

Arnaud Comment, Graham Knott, Yuhei Takado, Anders Meibom, Stéphane Laurent Escrig, Mojgan Masoodi

In mammals, glycogen synthesis and degradation are dynamic processes regulating blood and cerebral glucose-levels within a well-defined physiological range. Despite the essential role of glycogen in hepatic and cerebral metabolism, its spatiotemporal distr ...

NanoSIMS analysis of an isotopically labelled organometallic ruthenium(II) drug to probe its distribution and state in vitro

Kai Johnsson, Paul Joseph Dyson, Graham Knott, Mary-Claude Croisier-Coeytaux, Anders Meibom, Stéphane Laurent Escrig

The in vitro inter-and intra-cellular distribution of an isotopically labelled ruthenium(II)-arene (RAPTA) anti-metastatic compound in human ovarian cancer cells was imaged using nano-scale secondary ion mass spectrometry (NanoSIMS). Ultra-high resolution ...

Phenotypic heterogeneity in metabolic traits among single cells of a rare bacterial species in its natural environment quantified with a combination of flow cell sorting and NanoSIMS

Anders Meibom, Stéphane Laurent Escrig, Martin Ackermann

Populations of genetically identical microorganisms residing in the same environment can display marked variability in their phenotypic traits; this phenomenon is termed phenotypic heterogeneity. The relevance of such heterogeneity in natural habitats is u ...

Subcellular Investigation of Photosynthesis-Driven Carbon and Nitrogen Assimilation and utilization in the Symbiotic Reef Coral: Pocillopora damicornis

Anders Meibom, Stéphane Laurent Escrig, Christophe Kopp, Isabelle Domart-Coulon

UNLABELLED: Reef-building corals form essential, mutualistic endosymbiotic associations with photosynthetic Symbiodinium dinoflagellates, providing their animal host partner with photosynthetically derived nutrients that allow the coral to thrive in oligot ...

Ultrascale and Microscale Growth Dynamics of the Cidaroid Spine of Phyllacanthus imperialis Revealed by Mg-26 Labeling and NanoSIMS Isotopic Imaging

Anders Meibom, Stéphane Laurent Escrig, Jaroslaw Hubert Stolarski

Growth dynamics of the primary spine of the cidaroid sea urchin Phyllacanthus imperialis was assessed for the first time using pulsed Mg-26-labeling and NanoSIMS isotopic imaging. The sea urchin was incubated twice (for 48 h) in artificial seawater with el ...
