Pleased to share our preprint on a cultivation system for cable bacteria using artificial sediments, removing the variability of natural samples. The system supports growth, serial transfer, and recapitulates key geochemical gradients and microbial interactions.

Multiple fully funded PhD/postdoc positions available: experimental evolution of tumour suppression, egalitarian & fraternal ETIs, jumbo phage ecology & genetics. Related EoIs welcome.
Email CV/statement of motivation written in own words. Open until filled.
Grateful for reposting 🙏
Excited to share our paper in @cp-trendsmicrobiol.bsky.social
We explore how microbes can simultaneously use oxygen and alternative electron acceptors, reshaping how we think about respiration. We also discuss the evolutionary context and how it can be studied.

Retreat day 1🌿
Yesterday, CEM arrived at MolsLab in beautiful sunshine, kicking off our annual 3-day retreat dedicated to deep dives into CEM’s key research areas.
We spent the day in focused scientific group work across our core topics, bringing together diverse skills, backgrounds and disciplines
Deadline is April 20th! Let’s get those viruses

Glad to see our paper published in Nature Communications
We discovered how novel marine microorganisms interact via geoconductors to produce methane. www.nature.com/articles/s41...
The world’s oceans are losing oxygen—one of the most serious consequences of climate change. 🌊 But what impact does this have on microorganisms and organic matter cycles?🚢
To find out, biogeochemist @ggomezsaez.bsky.social and his team are traveling to Jutland:
Please help spread the word about this 3-year postdoc position in my team.
If your expertise & interest lie in studying how organisms from different domains of life (Bacteria and Archaea) communicate, come join us this summer in cozy Odense, Denmark.

Open position as an Associate Senior Lecturer/Assistant Professor in Molecular Microbiology at the Department of Biology, Lund University.
Apply before 28 April 2026. More info & application at lu.varbi.com/en/what:job/... Please share.

How do you make methane from phosphite? Through interspecies H2 transfer! Our paper on lithosyntrophy is finally published - read about how we resolved the metabolic interactions in this phosphite oxidizing, methanogenic enrichment culture! #phosphorus #methanogenesis www.pnas.org/doi/10.1073/...
Methane is the second most abundant greenhouse gas with a high heat-trapping capacity but a short lifespan in the atmosphere.
So-called “microbial methane munchers” can lower methane emissions from diverse ecosystems, as explored on the new #FEMSmicroBlog. #FascinatingMicrobes
I'm hiring my first postdoc! Apply by 20/4/26, position #20443. Seeking an environmental microbiologist with experience in metagenomics (preferably viromics) and molecular biology. Experience with targeted metabolomics is a plus.

"Previously in this class we used Prokka by @torstenseemann.bsky.social to annotate bacterial genomes. This always gave me an excuse to show an adorable picture of my daughter next to a quokka when she was a baby. Unfortunately, we are now using Bakta by @oschwengers.bsky.social."

Headline: "Scientists discover emperor penguin colony in Antarctica using satellite images"
Yesterday it was cows using tools, today its penguins using satellite imagery.
Oh that's cool, I'd never heard of shuf before. Neat exercise to try in other languages too, I just procrastinated from my real work by doing it in Julia:
