Cooling rates and melt extraction timescales determined by diffusion chronometry on shallow crustal plutonic rocks

Diffusion chronometry has emerged as a valuable tool to track the timescales of magmatic processes and is now routinely applied on erupted volcanic products to infer crystal residence times and mixing-to-eruption timescales. Despite some attempts to apply ...

Elemental cryo-imaging reveals SOS1-dependent vacuolar sodium accumulation

Anders Meibom, Stéphane Laurent Escrig, Cristina Martin Olmos, Priya Ramakrishna

Increasing soil salinity causes significant crop losses globally; therefore, understanding plant responses to salt (sodium) stress is of high importance. Plants avoid sodium toxicity through subcellular compartmentation by intricate processes involving a h ...

Host-derived organic acids enable gut colonization of the honey bee symbiont Snodgrassella alvi

Anders Meibom, Stéphane Laurent Escrig

Diverse bacteria can colonize the animal gut using dietary nutrients or by engaging in microbial crossfeeding interactions. Less is known about the role of host-derived nutrients in enabling gut bacterial colonization. Here we examined metabolic interactio ...

Fossil biocalcite remains open to isotopic exchange with seawater for tens of millions of years

Anders Meibom, Jaroslaw Hubert Stolarski, Stéphane Laurent Escrig, Cristina Martin Olmos, Arthur Adams, Deyanira Graciela Cisneros Lazaro

Fossilized remains of marine calcifiers constitute the physical basis for reconstructions of both deep ocean and sea-surface temperatures going back millions of years, but paleoclimate records derived from their isotope and trace-element chemistry can be b ...

Host starvation and in hospite degradation of algal symbionts shape the heat stress response of the Cassiopea-Symbiodiniaceae symbiosis

Anders Meibom, Stéphane Laurent Escrig, Cristina Martin Olmos, Nils Rädecker, Claudia Isabella Pogoreutz, Guilhem Maurice Louis Banc-Prandi, Gaëlle Delphine Toullec

Background
Global warming is causing large-scale disruption of cnidarian-Symbiodiniaceae symbioses fundamental to major marine ecosystems, such as coral reefs. However, the mechanisms by which heat stress perturbs these symbiotic partnership ...

Coupled carbon and nitrogen cycling regulates the cnidarian–algal symbiosis

Anders Meibom, Stéphane Laurent Escrig, Nils Rädecker

Efficient nutrient recycling underpins the ecological success of cnidarian-algal symbioses in oligotrophic waters. In these symbioses, nitrogen limitation restricts the growth of algal endosymbionts in hospite and stimulates their release of photosynthates ...

Stable isotope labeling and ultra-high-resolution NanoSIMS imaging reveal alpha-synuclein-induced changes in neuronal metabolism in vivo

Anders Meibom, Bernard Schneider, Graham Knott, Stéphane Laurent Escrig, Louise Helene Soegaard Jensen, Bohumil Maco, Sofia Carmen Suzanne Spataro

In Parkinson's disease, pathogenic factors such as the intraneuronal accumulation of the protein alpha-synuclein affect key metabolic processes. New approaches are required to understand how metabolic dysregulations cause degeneration of vulnerable subtype ...

Correlated cryo-SEM and CryoNanoSIMS imaging of biological tissue

Anders Meibom, Stéphane Laurent Escrig, Cristina Martin Olmos, Nils Rädecker, Florent Olivier Vivien Plane, Tian Cheng, Arnaud Comment, Louise Helene Soegaard Jensen

BackgroundThe development of nanoscale secondary ion mass spectrometry (NanoSIMS) has revolutionized the study of biological tissues by enabling, e.g., the visualization and quantification of metabolic processes at subcellular length scales. However, the a ...
