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

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 🧵

Bleaching: more than just a coral problem.

🌟 New book chapter alert! 🪸 Coral reefs are threatened by climate change, especially by mass ‘bleaching’ events. Bleaching is caused by the loss of photosymbionts under stress, resulting in a white – ‘bleached’ - phenotype. link.springer.com/chapter/10.1... #SymbioSky #MicroSky

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...

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.

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...

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...
