How do #cyanobacteria keep amorphous calcium carbonate (ACC) stable inside their cells?
Our new #JACS paper shows — via solid-state NMR — that a protein shell and water molecules stabilize ACC.

Two open PhD positions in molluscan biomineralization with the amazing Dr. Victoria Sleight at U. Aberdeen! See:
sleightlab.com/vacancies/ and sleightlab.com/phd-vacancy-2/. The first deadline is 15 December.
Intracellular amorphous calcium carbonate biomineralization in methanotrophic gammaproteobacteria was acquired by horizontal gene transfer from cyanobacteria https://www.biorxiv.org/content/10.64898/2025.12.07.689555v1
Le RN est une tartufferie et a montré, une nouvelle fois, son vrai visage. En commission j’avais déposé un amendement afin de financer et d’accélérer l’accessibilité des quais de gares pour les personnes handicapées et ... ils s’y sont opposés !!Lamentable

For a fews days (and nights) @biomin-impmc.bsky.social team is at Synchrotron Soleil on the Nanoscopium beamline. We are analysing different natural samples : cyanocatena, stromatolites, ancien fossils...
After a great talk from @marcamillet.bsky.social at the Goldschmidt Conference, you are now able to contribute your ideas for our future designs.
These visuals will be featured on AGC merchandises to be sold with the sole aim of supporting journal activities.

Cette année, ce sera ma première gorgée de @pintofscience.fr. Avec Juliette Pastore, je suis sûr que j’en garderai un excellent souvenir.
J’ai été surpris de cette anecdote qu’elle a rapportée dans l’émission signes des temps du 16 Mars selon laquelle un cours sur la théorie de l’évolution a été interdit à sciences Po. On a une version très différente par les responsables de sciences Po Reims www.marianne.net/societe/educ...

Mostly preaching to the choir here, but a group of us moderators over on Reddit's AskScience put together kind of an explainer for the implications of some of the attacks on science funding and infrastructure in the US if it's useful for anyone else to share:
