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

And including lab work work at @upvd.bsky.social and @hifmb.de

National Science Foundation fires roughly 10% of its workforce NSF fired 168 employees, leaving the agency less equipped to fund a wide range of scientific research.

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!

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

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

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. 🧫🦠

Classic GoPro 😂

But isn't this because scientists fear being considered advocates when they are just honest brokers?

Where are the fish? 😥

Also, 2 PhD and 1 postdoc positions coming in the second half of 2025.

Photosymbioses: A Coincidence of Evolution? - HIFMB Oldenburg The new working group "Photosymbiosis" investigates the coexistence of host animals and algae - the European Research Council provides funding of 1,489,000 eurosRead More

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:

Looks amazing. Congrats Raúl!

The new HIFMB building.

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

Plastid translocon recycling in dinoflagellates demonstrates the portability of complex plastids between hosts The plastids of photosynthetic organisms on land are predominantly “primary plastids,” derived from an ancient endosymbiosis of a cyanobacterium. Conv…

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

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.

Coral larvae increase nitrogen assimilation to stabilize algal symbiosis and combat bleaching under increased temperature Rising sea surface temperatures threaten coral-algal symbiosis, impacting reef ecosystems. This study shows that coral larvae alter nutrient metabolism by increasing nitrogen assimilation to maintain ...

And to thicken the plot, this aligns nicely with recent and highly complimentary excellent work by @cnidariana.bsky.social et al. journals.plos.org/plosbiology/...

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
