Nitrobacter NOB respond to environmental conditions by modulating their nitrite affinity, which highlights the importance of pre-culturing on experimental observations.

Very cool write-up by @ethz.ch on our recent paper in @nature.com on reconstructing dissolved organic carbon in the ocean through geologic time! Led by Nir Galili @eth-eaps.bsky.social ethz.ch/en/news-and-...

This thread is a delight.

Really glad to announce a new preprint from our lab: Global distribution of quinones in Bacteria! We here combine comparative genomics and text mining to leverage information on quinones distribution from thousands of articles describing new species and from dozens of thousands of genomes! 1/5

Happy to share that our story on the bacterial archaellum was published today in @natmicrobiol.nature.com www.nature.com/articles/s41... Congrats to the authors: @sshamphavi.bsky.social @loumollat.bsky.social @mariejoest.bsky.social Najwa Taib and @sgribaldo.bsky.social

I'm looking for a driven PhD student to join us at @au.dk and to both generate new paleoclimate data in the lab and work on computational problems to understand climate relationships across timescales. Get in touch if you'd like to hear more, and apply by Nov 1! phd.nat.au.dk/for-applican...

An assumption we long had in Earth Sci was that, in the geological past, more diversity meant more life in general. Someone finally got around to checking that, and it works! Biomass patterns follow the biodiversity curve. 🧪⚒️ Link: www.cell.com/current-biol...

🚨 Imagine a bacterium that refuses to follow the textbook: It grows as tangled filaments, divides unevenly, reshapes its own membranes… and even builds grappling hooks. Meet Litorilinea aerophila — and here’s why it blew our minds.

🚨 Paper alert! 🚨 After >1 year in review and six (6!) reviewers, I'm thrilled that this paper is finally out! Here, we provide the first data-based record of marine dissolved organic carbon in the geologic past. www.nature.com/articles/s41...

Excited to see our work about microbial interactions between anaerobic species in a synthetic community (co-, tri-, and quad-culture) degrading cellulose to methane published in ISME Communications!

🚨 In case you missed it… our 4-year time-series analysis of Arctic Ocean viruses is out now! Near-monthly samples — including through the dark, cold, polar winter ❄️ — using long-read metagenomics. Short thread 🧵👇

I have a fully funded open #position for a PhD student/postdoc in marine #biogeochemistry. As part of the MARBEDS project, we are seeking someone to study seafloor fluxes and their interactions with microbial communities in biodiversity hotspots. 🧪⚒️🌊 Contact me if you want more details.

Question for bluesky hive mind: I want to upgrade my office set up for small presentations and joined work on a document without having to squeeze around my desk. I have some ideas, but what solutions are people using? Any good recommendations or things to avoid?

Would you like to work with us? At JAMSTEC, we are recruiting postdoctoral researchers through the Young Research Fellow program. This program allows fellows to independently pursue their own research projects. www.jamstec.go.jp/recruit/e/jy...

Wonderful write-up by the amazing @fatimagulhusain.bsky.social on our recent PNAS paper: eaps.mit.edu/news-impact/...

Working on the interface of organic geochemistry and archeology? Have an exciting dataset that is ready to write up? Or one of those papers that has been a draft since the Stone Age? Consider this special issue to publish your research, submission by 01/09. shorturl.at/O3gzV

#ECR attention! Just finishing your #PhD and wondering if the DFG’s Walter Benjamin Programme might be a funding option for you? Come and find out in our info talk in our research career series #Prospects (in English). The link to the meeting will be published here: ➡️ www.dfg.de/en/research-...

In our study, we showed that intestinal Methanosarcinales have reduced genomes and obligately dependent on H2 and CH3 compounds for #CH4 production. They lost the Wood–Ljungdahl pathway and membrane complexes (Rnf, Fpo, Ech). academic.oup.com/femsec/artic... @femsjournals.bsky.social @femsmicro.org

I'm honored to be named as an Ocean Discovery Lecturer this year. If your institution doesn't have much for seminars, but you want to learn about fish and sharks through time or the awesome work by the other lecturers, this is a great chance to bring someone in! usoceandiscovery.org/lecture-seri...

#WeekendReading: Hoogakker (and 67 other people) go into the current state of low-oxygen proxies currently in use in paleoceanography. It's a small book (95 pages), more than a paper, and covers a lot. 🧪⚒️ bg.copernicus.org/articles/22/...

Part of the Pacific Ocean seabed was mined in 1979. 44 years later, marine life in the area has still not fully recovered www.newscientist.com/article/2469...

A friend included this anti-acknowledgement section on her PhD thesis. She also added the proposition: “Systematic bullying and undermining of girls and women in STEM starts early on and is the reason why they do not stay in science and related fields.” Absurd we still need to go through this 🧪👩‍🔬

Hello everyone, the STAMPS course on microbiome data analysis at @mblscience.bsky.social is open until Mar 11, 2025! Join us for a great experience! Please ALSO check out my co-Director @amydwillis.bsky.social excellent post on how to write a great application: statdivlab.github.io/blog/article...

It's a huge honor to receive the Alfred Treibs Award and to be placed in a list of researchers that I have always looked up to. I owe a lot of gratitude to my colleagues and all ECR that have been part of the organic biogeochemistry group at NIOZ for always pushing me forward.

Geochemists and seismologists unite! Both fields contribute to understanding Earth's structure and tectonic movements - now they can publish in an #OpenAccessJournal too! Welcome @weareagc.bsky.social, now accepting submissions. Support your fellow geochemists!

You know how some people like coriander and some can't stand it, but it seems there isn't anyone in between? The thing is, not liking it - is genetic. A variation in one gene affects some people's olfactory receptors, which makes it taste like soap or dirt. 🧪 link.springer.com/article/10.1...

Just published! 🎊 Effects of lipid membranes on RNA catalytic activity and stability 🧬 onlinelibrary.wiley.com/doi/full/10.... @bcube-tud.bsky.social

Back in 2019 we screened an obscure lineage of bacteria for a side project and noticed something quite unusual. A quinone, used in cellular electron transport, that looked similar to the type used by plants and algae to perform photosynthesis.

🌍❄️ Applications now open! Join the 17th ECORD Summer School at MARUM, University of Bremen, from 8–19 September 2025. 🔬 Theme: Southern Ocean – Antarctic Paleoclimate Interactions 🌊 Explore the impact of the Antarctic Circumpolar Current & ice sheet stability on global climate.

Very happy to have played a (small) part in this excellent paper in @pnas.org by @lipidorama.bsky.social! Here, Felix et al. show the existence of a new type of quinone in N-cycling bacteria, with some big implications for aerobic metabolism timing vis-à-vis the GOE 🎉 www.pnas.org/doi/10.1073/...

Well the award for most cowardly, boot-lickingest academic society has squarely gone to the American Society of Microbiology, who has taken down features of various non-white scientists. Absolutely pathetic behavior. Those articles are now coming up as “under review”. Truly sickening cowardice here.

American Society for Microbiology is scrubbing it's website of inclusivity articles and spotlights as we speak. The largest microbiology publisher in the world appears to be actively removing scientific paper papers by member-authors who might be perceived as DEI (IDEAA) #asm #mccarthyism

Final push I needed to delete my Twitter/X account.
