Beautiful new pre-print by @lambdapp.bsky.social! Rather than asking whether microbial interactions are mainly positive or negative, Prajwal asks: how strong or weak are they and why? The answer: not Gaussian, but skewed. This is similar to larger organisms, but not for the same reason. Read it!

Very happy to share that the work I've been doing with @saramitri.bsky.social is now out on biorxiv! www.biorxiv.org/content/10.6... We broadly ask how are microbial interactions distributed, is there a common shape across datasets, what drives it, and why it matters. Summary thread below 🧵 1/17

Interested in coming to Berlin on a Humboldt Fellowship? Please consider the new modalities: There are 3 calls for applications annually, each opening 8 months before the respective selection meeting. The new call opens on 15 July 2026, closing once 800 applications are in.

Eye-opening work by @olimeacock.bsky.social (former postdoc, now PI in Sheffield). He presents an exact mapping from steady-state consumer-resource to generalized Lotka-Volterra models, revealing that cross-feeding can lead to competition for other limiting resources. Feedback pls!

New preprint from @saramitri.bsky.social and me: tinyurl.com/3dsjnm4d The headline result - we derive a general way to connect mechanistic ecosystem models to the gLV equation. This reveals that strengthening cooperative mechanisms can make effective gLV interactions increasingly competitive. Weird!

"A project by ECRs for ECRs" to quote @olimeacock.bsky.social This review of ideas in classical ecology to compile a "field guide" for microbial ecologists is the result of a year-long journal club across several labs in Switzerland. Beautiful process, beautiful outcome! Congratulations all authors!

It was a great pleasure to be a part of this and I learnt so much during the process as well! Check it out when you get some time and thanks to all the co-authors for great work! 🙌

Come and work with us in a beautiful corner of Germany: 5 years of funding for your microbiology research and lots of great colleagues 🦠🧫

Check out Snorre's latest preprint: www.biorxiv.org/content/10.6... I love this story: our 4-species synthetic bacterial community coexists across many simple environments and conditions. We show why (spoiler in the title)

Happy to finally share these results: Cross-feeding enables robust coexistence between four bacterial species www.biorxiv.org/content/10.6... With @saramitri.bsky.social @lambdapp.bsky.social @dan1elmachado.bsky.social @lhtxra.bsky.social Eric Ulrich, Alisson Gillon & Sam Testa #microsky

It looks like there will be an open postdoc position in my lab soon. I'll be looking for someone with substantial wet-lab experience in microbiology / microbial ecology / evolution / physiology. If everything goes well, an ad will be coming. But if you know someone, ask them to reach out already.
