Shortlisted candidates will be invited to give a seminar at the Fellows Conference, which will be held on 10 March 2026.

Candidates who win Fellowships will be offered a Tenure Track Group Leader position from the outset, initially for 5 years.

Identification of optimal fluorophores for use in the Drosophila embryo by Timothy E Saunders and team: www.biorxiv.org/content/10.1...
Figure 1: Fluorophore intensity in the Drosophila blastoderm (n.c. 14). Comparison of (A) green and (B) red fluorescence intensity using the same intensity scaling in n.c. 14. The fluorescence signal did
not saturate. Shown are single imaging planes. Normalised histograms of fluorescence intensity for green (C) and red (D) fluorophores averaged across at least n=3 embryos per line. Scale bars = 20 μm

It is not only antibiotics but also certain viruses – known as bacteriophages – that can kill off pathogenic bacteria. However, Switzerland lacks the legal framework for the use of these viruses in therapy. What would need to change? Researcher Alexander Harms explains.

Nice work on tackling genetic interactions in the pneumococcus! If you like this, you will also like our work doing the same thing using dual CRISPRi. Coming soon in @cp-cellsystems.bsky.social www.biorxiv.org/content/10.1...

🎓 Today, I successfully defended my PhD!
It’s been a long journey and I’m incredibly grateful for all the support, lessons, and growth along the way. A huge thank you to my committee members — Nina Khanna, Dirk Bumann, @veeninglab.com , and @mkjos.bsky.social — for their guidance and encouragement.

Looking for a new approach to studying or eliminating phages? Check out our study introducing anti-phage ASOs (antisense oligos) out in @Nature today. nature.com/articles/s4158…

It will be interesting to test whether induction of RipA leads to stalled replication and subsequent increased comCDE copy numbers and that this is the mechanism for triggered competence. Seems like a simple experiment but they don't like this hypothesis for some reason 🤷‍♂️

Preprint: De-novo design of proteins that inhibit bacterial defenses

Our approach allows silencing defense systems of choice. We show how this approach enables programming of “untransformable” bacteria, and how it can enhance phage therapy applications

Congrats Jeremy Garb!

Synthetically designed anti-defense proteins overcome barriers to bacterial transformation and phage infection
Bacterial defense systems present considerable barriers to both phage infection and plasmid transformation. These systems target mobile genetic elements, limiting the efficacy of bacteriophage-based t...

🚨 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.

Lots of new conditionally essential genes identified, opening up lots of future applications and research directions for this important bug. Many congratulations to all authors and feedback is welcome!

Of course, we ( @axeljanssen.bsky.social) setup a genome browser with a track with sgRNA target sites for easy target validation and gene hunting

Great collaboration with the lab of Junkal Garmendia, spearheaded by Celia and Johann. First we setup CRISPRi for this bacterium and then generated a genome-wide sgRNA library that allows us to do CRISPRi-seq.
