Ribosome -less zombies in the ocean 🦠🧟

Irrespective, I am feeling extremely honored to receive such a prestigious prize 🤩

Thanks everyone who helped me on the way!

To be honest, I don’t know …

Let me speculate:
Bruker uses MALDI to analyze ribosomal proteins and thereby identify microorganisms.

The zombie cells I discovered are devoid of ribosomes. An identification would, thus, not be possible …

Whooaaa
My zombie cells and I received the Bremer Studienpreis for my PhD 🤩🤩🤩🧟‍♂️

I received a special price sponsored by @brukercorporation.bsky.social Daltonics, who produce mainly mass specs. It was quite a surprise, considering I didn’t use mass spectrometry in my PhD. Why did they choose me? 🧵

I am very excited to announce that a fully funded PhD position is available in my group.

Topic: Synergistic coevolution in mono-specific and multi-species microbial consortia

Please RT or forward this information to interested candidates.

Deadline: 11.01.26

Benchmarking with synthetic communities provides a baseline for virus-host inferences from Hi-C proximity linking Virus discovery has accelerated but linking viruses to hosts remains challenging. This study uses synthetic microbiomes to optimize and benchmark Hi-C for virus-host linkage inference, and applies thi...

🚨NEW paper: Benchmarking Hi-C for virus–host inference
journals.plos.org/plosbiology/...

A clear baseline for anyone mapping virus–host interactions that establishes robust, benchmarked thresholds for Hi-C linkages.

Yes, some people's legacies are complicated. For example, Watson. After all, though he was racist, don't forget his other traits. For example, he was also sexist. And also anti-semitic. And a data / idea thief. So let's not forget all the different facets.

Zombie cells in the ocean, a perfect topic for Halloween here at RD3 of GEOMAR. Great talk by @janbruewer.bsky.social it was great to have you here.

Zombie cells? 🧟😨 Sounds spooky, and it is past #Halloween.

These #SAR11 are attacked by #viruses and in between life and death. Off #Helgoland, every 10th cell was a zombie. 🌊

Mineralwasser: Still, medium, sprudelnd – und ein Riesengeschäft Mineralwasser ist das meistverkaufte Getränk in Deutschland. Bisher können Hersteller das Grundwasser dafür fast kostenlos aus dem Boden holen. Dagegen regt sich Widerstand

Die SZ schreibt: “Würde ganz Deutschland auf Mineralwasser verzichten (also nur noch Trinkwasser aus der häuslichen Leitung trinken) könnten anderthalbmal so viele Treibhausgasemissionen eingespart werden, wie der gesamte innerdeutsche Flugverkehr verursacht.”

Many thanks to the great team for representing our institute and joining the fun at #BremerFirmelauf 2025!

Discover our 6 winning projects! - Pure Ocean Fund We are delighted to unveil the winning projects from the 2025 Pure Ocean Call for Projects.

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

🏆 Research integrity consultant and image forensics expert @elisabethbik.bsky.social has uncovered fraudulent data in over 7,600 scientific papers and exposed the practices of ‘paper mills’ that produce counterfeit scientific articles. She is honoured with the €200K Individual Award. Congrats!

In der Hölle. Ein verdutzt guckender Mann steht mit einem Schild im Fegefeuer, darauf steht: "Wir sind die Mehrheit", darunter der AfD-Pfeil. Vor im steht Satan und sagt freundlich: "Hier stimmt das wirklich!"

Danke an alle, die gestern auf der Straße waren.

I always thought very little of my first publication … I mean: It was my BSc thesis, so expectations should be realistic.

Anyways, today, I read it again and … I enjoyed reading it! Is this normal?

Thanks to @reefgenomics.bsky.social & Shobhit, who helped me with writing back in 2017 🙏🏼

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

Wooooooow. Congrats!

Verrucomicrobiota are found everywhere, yet we know very little about this group. Here, @iwilkie.bsky.social described and named an unrecognized marine group (previously known as MB11C04). Here, we introduce Seribacter and Chordibacter bacteria.
