New paper on using #coral nurseries as experimental units for studying host x symbiont genotype interactions. Congrats to recent PhD student (now Dr.) Matt Gamache! @cmarinescience.bsky.social rdcu.be/eVA2C

🧪 Dr. Emily Aguirre's final dissertation chapter is published! She isolated a putative bacterial symbiont then cocultured it with axenic algal symbionts to ask how it impacted growth and gene expression - results were unexpected but do support a beneficial relationship - read more here rdcu.be/eUKQz

Big thanks to my supervisor @prhsteinmetz.bsky.social and coauthors @noahbruderer.bsky.social @lionlchristiaen.bsky.social at🇳🇴 @msarscentre.bsky.social ⬇️🧵

Proud to see the PhD work of @inesfournon.bsky.social out as preprint! 🌸 Cell extrusion DOES exist outside of bilaterians AND is sensitive to feeding status in sea anemones.

New preprint characterizing a protein likely required for vertical transmission. Some really stellar undergrads contributing to this work too! A secreted endosymbiont protein essential for colonizing host cells

Results I'm sad to share but must be told - branching coral are now functionally extinct in Florida - to learn more check out the full study www.science.org/doi/10.1126/... and our personal summary theconversation.com/2-iconic-cor...

After a searing ocean heat wave in 2023, two of the most historically important coral species in Florida are functionally extinct from the state’s reef, scientists have found.

This is an INCREDIBLE advance in our understanding of coral diversification. 🪸🎉 Fantastic new work led by @claudiavaga.bsky.social www.nature.com/articles/s41...

Beautiful work on characterizing the symbiosome of Aiptasia. Further evidence that “ongoing digestion” is central to a stable endosymbiosis.

We are happy to share our latest work in @nature.com . We study the genomic and cellular basis of facultative symbiosis in Oculina patagonica - a Mediterranean coral remarkable for its ability to survive long periods without algal symbionts. Led by Shani Levy and @xgrau.bsky.social rdcu.be/eLbaZ

🧪🌏 Cool results from @pcleves.bsky.social, re: basic mechanisms of coral-algal symbiosis. www.biorxiv.org/content/10.1... (1) Symbiotic vacuoles are arrested lysosomes. (2) The bicarbonate transporter for the coral's carbon concentration loop is SCL26A11

We're excited to share with everyone a preprint of our manuscript that resolves the cellular origins of the symbiosome in cnidarian-algal symbiosis through proteomics of the symbiosome, RNAi, and CRISPR/Cas9 experiments. ⬇️ www.biorxiv.org/content/10.1... Read on below! 1/12 🧵

Learning about science is always rad. But as the Animal-Microbe Symbiosis GRC wraps up, I'm most excited about whom I get to do that science with.

Just left the Animal-Microbe Symbioses GRC feeling grateful for this research community and its big heart...at a time when academia/science are under attack in the U.S. and when actual wars are raging, and people dying, the vibe reminded how the"lingua franca" that is science bridges the divides.

Started a starter pack for the presenters and attendees of the 2025 Animal-Microbe Symbiosis Gordon Research Conference. Let me know if I should add (or remove) you! go.bsky.app/Pnzz1R9

Science has published a letter I helped write, as part of Advancing Queer & Trans Equity in Science (AQTES), about why it's important for universities & other institutions to protect trans and gender-nonconforming scientists, and some practical things they can do. www.science.org/doi/10.1126/...
