The industry’s sales pitch is incorrect,” says Daniel Pauly, director of the @seaaroundus.org project. @science.ubc.ca english.elpais.com/climate/2026...
Aquaculture is depleting the oceans: A farmed salmon can consume more than six times its weight in wild fish
The rapid growth of the industry has increased demand for fishmeal and fish oil, creating environmental and social costs that are often felt far from the consumers who buy the final products

🧬🌱 Algal chloroplast ribosomes have a unique arm domain, revealed by cryo-ET and cryo-EM. It may stabilize mRNA and organize polysomes. Chloroplast translation is more structurally diverse than expected. #plantscience @natplants.nature.com www.nature.com/articles/s41...
Chloroplast-encoded small subunit extensions reshape the Chlamydomonas chlororibosome - Nature Plants
Using in situ cryo-electron tomography, researchers found a unique ‘arm’ domain on the small subunit of Chlamydomonas chlororibosomes. This discovery suggests that chlororibosome structure is more evo...

Freaking finally! A massive compilation of data that sat on various desks for almost a decade is finally out. On the positive side, gave me time to learn expansion microscopy and make Fig 1 www.science.org/doi/10.1126/...
Emergent metabolic parasitism driven by organelle sequestration
Chloroplast-stealing ciliates evolve, increasing reliance on their prey for all aspects of metabolism, including photosynthesis.

Integration and regulation of stolen organelles in a marine protist
Abstract. Chloroplast-stealing (a.k.a., “kleptoplastidic”) plankton transiently obtain and integrate prey metabolic machinery into their own cells. To do s

Sailing in @biorxivpreprint.bsky.social ready for summer, our study on the iconic Portuguese man o' war 🪼 is out: www.biorxiv.org/content/10.6.... We use (epi)genomics to understand a critter that fascinates me since childhood. Massive team effort with @obog.bsky.social, Cummins and Neely groups. 🧵
Dives in Bermuda a couple times ---> changes research focus so that I ✨️have✨️ to dive for sample collection, and literally no other reason 🤩😍🤩😍
Every time I'm here it feels more and more like my home away from home 😊
Check it out! Deeper insights into the pyrenoid of Chlorella. More evidence Rubisco has convergently evolved as an organising hub, cool membrane architectures and evidence that most of the rest of the CCM is conserved with other green pyrenoids! 💚 Preprint here 🔗: www.biorxiv.org/content/10.6... 🔗
(1/16) Nearly two-thirds of ocean carbon fixation flows through a diverse organelle: the pyrenoid. Our new paper maps its 3D architecture in the alga Chlorella and identifies new proteins — expanding the toolkit to engineer this CO2-concentrating machine into crops🧵 #Pyrenoid #CCM #Photosynthesis
People say scientists are serious but marine biologists will spend hours quietly sitting around tables drawing on styrofoam cups and then tying said cups to deep sea submarines Because ocean pressure will squeeze the air from the cups And we are but human & we want tiny cup
Apparently the "boring billion" was actually exciting! We provide molecular evidence of complex Mesoproterozoic eukaryotic communities. So happy to see this out 🥳 Thanks to @phoebefossil.bsky.social , Hélène Morlon & @fburki.bsky.social for a lovely collab! doi.org/10.1073/pnas...
Back in Bermuda @biosstation.bsky.social again for fieldwork!!! I am here alone, despite my prolific attempts to convince people to join me on this trip 😜
Plastid endosymbiosis without gene transfer - dinoflagellates can do it #ProtistsOnSky #Kareniaceae #plastids
Recent plastid replacement in Karlodinium ballantinum (Kareniaceae, Dinoflagellata) challenges the paradigms of endosymbiotic gene transfer
Abstract. Plastids, the photosynthetic organelles of eukaryotes, arose via endosymbiosis of cyanobacteria by a eukaryotic host and were subsequently spread

It’s #WormWednesday and we’re busy processing buckets of sand we just brought back from the Florida Keys! We’re picking out Stilbonematid nematode worms to study their bacterial symbionts. We call this one “Chewbacca” because…well, it looks like a Wookie’e leg (the “hairs” are Thiosymbion bacteria)
I recently did this interview with NEB covering a lot of the work I've been involved with lately (e.g. @dudinlab.bsky.social) Hopefully there's something interesting in there and nothing too egregious! Some of the work fits #protistsonsky. Enjoy? www.neb.com/en-us/podcas...

Our paper "Gene ancestries reveal diverse microbial associations during eukaryogenesis.” is finally out in Nature. Eukaryogenesis was likely a gradual process shaped by multiple microbial partners and virus-mediated gene transfer, rather than a single binary symbiosis. doi.org/10.1038/s415...
Meet Holdonia, a new member of the chrompodellid clade. Found clinging to a polychaete, this little guy reveals that similar patterns in plastid reduction have occurred independently across chrompodellid and related lineages. @rhizalyssa.bsky.social @pjkeelinglab.bsky.social tinyurl.com/2t25xb6z

Today marks 30 years since we identified the apicoplast, a relict plastid in human and animal parasites (PMID 8632819). Apicoplasts are the target of the widely used antimalarial prophylactic doxycycline, which has saved many thousands of malaria infections.

it has been a real pleasure to co-run the Life of Retaria with such a lovely group of organizers 💕Happy two years of the Life of Retaria Seminar Series!!!! 🎉 it feels right that our paper should come out around the anniversary!
The first paper from #theLifeOfRetaria is out! doi.org/10.1002/bies... This was a very fun and enriching process, as it has been the last 2 years of our Seminar Series 🤩 #protistsonsky
