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 ...

Enzymatic absorption promoters for non-invasive peptide delivery

Cristina Martin Olmos, Angela Steinauer

Peptide drugs offer considerable potential for treating a diverse range of diseases. Yet, their clinical application is generally restricted to injectable therapies. The main challenge hindering their broader use through globally accessible, patient-friend ...

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 ...

Symbiotic nutrient exchange enhances the long-term survival of cassiosomes, the autonomous stinging-cell structures of Cassiopea

Anders Meibom, Cristina Martin Olmos, Nils Rädecker, Claudia Isabella Pogoreutz, Guilhem Maurice Louis Banc-Prandi, Gaëlle Delphine Toullec, Niclas Heidelberg Lyndby

Medusae of the widely distributed upside-down jellyfish Cassiopea release autonomous, mobile stinging structures. These so-called cassiosomes play a role in predator defense and prey capture, and are major contributors to “contactless” stinging incidents i ...

Nanoliter Liquid Packaging in a Bioresorbable Microsystem by Additive Manufacturing and its Application as a Controlled Drug Delivery Device

Jürgen Brugger, Arnaud Bertsch, Cristina Martin Olmos, Jongeon Park

Precise packaging of nanoliter amounts of liquid in a microsystem is important for many biomedical applications. However, existing liquid encapsulation technologies have limitations in terms of liquid waste, evaporation, trapped bubbles, and liquid degrada ...

Integrating environmental variability to broaden the research on coral responses to future ocean conditions

Cristina Martin Olmos, Nils Rädecker

Our understanding of the response of reef-building corals to changes in their physical environment is largely based on laboratory experiments, analysis of long-term field data, and model projections. Experimental data provide unique insights into how organ ...

Integrated elastomer-based device for measuring the mechanics of adherent cell monolayers

Herbert Shea, Alexandre Poulin, Cristina Martin Olmos, Francesca Sorba

Cells in the body collectively sustain mechanical deformations in almost all physiological functions. From the morphogenesis stage, cells' ability to sustain stress is essential for the body's well-being. Several pathologies have been associated with abnor ...
