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

Bleaching: more than just a coral problem.

I just returned from my holiday in Finland. While we were looking for bears, wolves and co, one of my personal favorites were these green-alga bearing freshwater sponges. Photosymbiosis is everywhere if you look close enough. Maybe it‘s time for some freshwater work at @hifmb.de?

My first dive into Raman microscopy! 🔬 Our latest heat stress experiments on Aiptasia raised more questions than answers — until a few days of Raman spectroscopy with Dr. Peter Mojzeš at @charlesuni.cuni.cz helped connect the dots. Grateful for the collaboration and excited about what’s ahead!

Many amoebae incorporate diatoms in their shells, but Cylindrifflugia bacillariarum is the master. Third and fourth pics are close views of the glue that holds it all together. #ProtistsonSky #Amoebae #Peatlands

Looking forward to exploring how algal symbionts enable anemones to cope with the environmental conditions of the Mediterranean and the Anthropocene. Thanks @pure-ocean.bsky.social! A fun project lead by @cpogoreutz.bsky.social and together with Christine Ferrier-Pagès. tinyurl.com/pureocean

Yesterday was the darkest day of my professional life so far. Many of NSF’s best and brightest people fired indiscriminately. The terms of their firing cruel. My colleagues matter, they are valued and they make a difference. I have no words. www.npr.org/2025/02/18/n...

A beautiful evening with friends, great discussions, and even some science! Excited to call this place my (work) home.

Interested in protist parasites? Want to learn some fun bioinformatics? Think this apicomplexan looks cool? Great! Come and do some protist genomics at @uniofbath.bsky.social! We're advertising a fully-funded PhD studentship open to UK & International applicants! www.findaphd.com/phds/project...

Stoked about this manuscript, many years in the making. We present an original resource of ~700 highly curated plastid MAGs of marine pelagic algae. Among these we found a novel deep branching group of plastid genomes; we informally call them leptophytes www.biorxiv.org/content/10.1...

Application deadline now extended to January 12th, some extra time to enjoy the winter break! ☃️🛷🎅

What a great finale. Receiving the Zeno Karl Schindler Research Prize marked the perfect end to an amazing time as a postdoc at EPFL🇨🇭. Big thanks to the Laboratory for Biological Geochemistry for being awesome friends and colleagues throughout these years!

We have a new paper out today in #ScienceAdvances from a #COVIDcollab with postdocs Kevin Archibald, Suzana Leles, and Ferdi Pfab. Our #MOCHA☕💻🦠 team developed a new model to describe how #mixotrophs optimize metabolism. www.science.org/doi/10.1126/... #protistsonsky #NSFfunded (1/6)

Endosymbiosis remodels transporter expression in Phaeocystis algae. Beautiful work from the @johandecelle.bsky.social lab. It would be amazing to know whether the patterns in diurnal transporter expression also change the directionality of transport. 🧫🦠 academic.oup.com/ismej/advanc...

Welcome @radecker.bsky.social! As head of the new HIFMB focus group #Photosymbiosis, he investigates the coexistence of host animals and algae, how symbioses occur and what determines whether they succeed or fail. More about the focus group and Nils' EU-funded project “PhagoPhoRe” here:

I am thrilled to announce that this will be my new workplace. I am joining @hifmb.bsky.social today to start my new focus group on host-microbe interactions in photosymbioses. Looking forward to meeting old and new friends and exploring new collaborations. 🦠🧫🪸 #microsky

This really is an excellent paper. It shows that plastid protein import machinery can be inherited through serial transfer, and that we should not expect additional membranes in tertiary plastids. In other words, serial transfers got easier to explain www.sciencedirect.com/science/arti...

A reminder - as understood by Lynn Margulis - that cooperation is the foundation of life. And that biology does not lend itself to simplistic, mechanistic explanations. "Blurring traditional boundaries between ecto- and endosymbiosis" www.nature.com/articles/s41...

The results of a great collaboration finally out. Symbiotic carbon recycling in coral larvae is enhanced by elevated pCO2 and moderate increases in temperature. 🪸🧫 #Symbiosky

New paper alert! Does photosynthesis actually have a role in symbiosis establishment between sea anemones and their intracellular algae? A previous study suggested not, but we found otherwise, especially when looking at anemones long-term and what's going on with their larvae!

Similar to coral bleaching, heat stress disrupts the symbiosis between the upside-down jellyfish Cassiopea and its algal endosymbionts. Check out @gaelletoullec.bsky.social‘s latest paper on why bleaching in Cassiopea can be invisible nonetheless. @cpogoreutz.bsky.social 🪸🧫🦠🔬 tinyurl.com/yu55ja25

Our paper on resource competition in the cnidarian-algal symbiosis is finally out. shorturl.at/gklxP we show that host and symbiont use photosynthates to fix ammonium. The resulting resource competition shapes the phenotype and defines ecological niche of the symbiosis. @reefgenomics.bsky.social 🪸🦠🔬

Fun time in the field! You’d be forgiven to think Laura was studying Mediterranean monk seal ecology. But that well camouflaged blob next to her is actually me trying to help with sampling anemones.

bioRxiv goes big on Bluesky: accounts for all subject categories now available (Please Reskeet) connect.biorxiv.org/news/2023/09...

Ever wondered what function the white granules in Cassiopea might have? In our latest work we use OCT to investigate the micromorphology and optical properties of Cassiopea tissue, and show that white granules enhance photosynthesis of nearby symbionts. royalsocietypublishing.org/doi/10.1098/...

🎓 Congratulations to the brilliant Dr. Gaëlle Toullec on successfully defending her PhD thesis on symbiotic nutrient cycling in the upside-down jellyfish Cassiopea. 🌊🪸🪼🔬#PhD #MarineScience

Could active algal removal accelerate coral recovery? Maybe, but at what cost? Algae help retain nutrients in the ecosystem following coral mortality. In an oligotrophic ocean, “sea-weeding” could help with short-term coral recovery but slow down reef nutrient capacity recovery in the long-term. 🪸

Very exciting read! I always dreamed of visualizing osmoregulation in action. Now it’s time to look at these processes in the CryoNanoSIMS.

That feeling when you spent three weeks on a NanoSIMS mosaic just to falsify your initial hypothesis… At least 15N-ammonium uptake in the Hydra-Chlorella symbiosis looks pretty. #microsky #evosky 🧫🦠🔬
