“ERC succeeds because it’s different. Its simple, tailored procedures allow Europe’s best researchers to thrive. Bureaucratic processes designed for other programmes should not be imposed on it.” @marialep.bsky.social spoke up for an independent ERC with a doubled budget today @europarl.europa.eu

'In Germany in the 1930s, scientific institutions and societies failed at every level to offer any significant resistance to Nazism,' writes @philipcball.bsky.social. 'Donald Trump’s United States is not Hitler’s Germany. But the point is surely to learn from it anyway.'

Still nothing.

So.. I really hope NCBI GenBank is not working just.. very temporarily and for unrelated reasons.

One of my favorite radiolarians. I call it a "little hat", but I guess it is probably Eucecryphalus sp. Here are two examples from Bermuda (Atlantic) and Puerto Rico (Caribbean). Exquisite little #protistsonsky. I love seeing these forms in different regions of the Oceans. #protistaday #marinelife

Reposting this again - We are looking for a postdoc to study the physiology, evolution, and cell biology of anaerobic ciliate-methanogen symbioses using 'omics, experiments, and/or microscopy. Still accepting inquiries, and I would love to hear from interested candidates.

Farewell, John! Thank you for the awesome visit and let's get that rad bucket of gold! @burnsajohn.bsky.social

A nasselarian radiolarian with its podoconus (cone-like arrangement of long arms) out and lots of internal movement. Beautiful to see! In the water column, that cone of arms is probably oriented "up" for catching debris/prey and managing motion with the hard skeleton pointed "down" #protistaday

Is it a repeat? Sort of, but this is a radiolarian in motion! I wanted to see how dynamic the symbionts are. They mostly stay still over a couple of minutes. With @micrott.bsky.social and @evocellbio.bsky.social #protistaday #protistsonsky #marinelife

Daniel Mendez-Sanchez & Anna Schrecengost's paper on symbionts of anaerobic ciliates featured in a nice phys:org article! @annaschreck.bsky.social @symbiosisrox.bsky.social

Also check out out other paper published in the same issue of ISME: academic.oup.com/ismej/articl... Together I think these papers tell a really nice story about the evolution and transmission dynamics of anaerobic ciliate-methanogen symbioses, both freshwater and marine #ProtistsOnSky #SymbioSky

We're so happy to have John Burns (and radiolarians) here in Puerto Rico! Thank you for all the cool science and fun! #ProtistsOnSky #MicroSky

"Hey wait for meeee!" Said the little radiolarian. #protistaday #protistsonsky #marinelife. With @micrott.bsky.social and @evocellbio.bsky.social

Today a radiolarian #protistaday from the Caribbean. It is a privilege to have the means, support, and interest to Research the curious cell biology of radiolarians. I have many like this to share and will hopefully have opportunities to dive into their cell bio in the future. 🦑 #protistsonsky

CIMA & UPRM students, our second guest seminar is TODAY at 3:30 pm in CCRI/online! See you all there!

Okay... #protistaday. I know this is a phaeodarian, but how does a cell evolve to build a glass mouth, teeth and all, to live inside? This is totally amazing. #protistsonsky #marinelife. With @evocellbio.bsky.social @micrott.bsky.social

CIMA & UPRM, see you all today at 2 pm in CCRI or online! (dm me if you haven't received the link): John Burns, Bigelow Laboratory for Ocean Sciences – Viernes 6 a las 2:00 - La visión generalista de la forma y la función en la vida eucariota 🔬🧬🧫🧪🏝️ #ProtistsOnSky #MicroSky @burnsajohn.bsky.social

This is great. Yet, protists remain hidden to science. There is a protistology starter pack, right? #protistsonsky

Understanding the origin of eukaryotic cells is one of the biggest puzzles in biology 🧩 As genomic data expand, painting a clear picture of LECA requires analytical resources and a commitment to data sharing. This paper led by T. R. emphasizes a community-driven approach to tackle this complexity.

Fun sampling mangrove sediments with my students today! Logistics difficulty: 0/10 - we literally just walked down the lab, as Isla Magueyes is surrounded by mangroves all around. Love the island!

Want to be amazed by how a symbiont can be located at the center of a cell while still being an epibiont! Please read and be amazed by the symbiosis between Anaerameoba and sulfate-reducing bacteria! Now out in Nature Communications (open access)! rdcu.be/dZGNe (1/11)
