Very excited to announce that we are hiring for three faculty positions at @universityofleeds.bsky.social in @bioscienceleeds.bsky.social: A/Prof Plant Science, A/Prof Animal Biology and Lecturer in Ecology, Zoology, Biodiversity or Ecosystem Management. Please do get in touch to chat. Links below:
🚨Preprint! Happy to share the research from my PhD “Genome delivery of a contractile tailed phage and its superinfection exclusion mechanism”. We use cryoEM to study the genome ejection of the phage T4, revealing how the tape measure protein regulates the process.

Final version @nature.com of our paper describing unconventional multicellular development in a choanoflagellate inhabiting an extreme environment. A ton of new data since the first @biorxivpreprint.bsky.social preprint (which we've kept updating).
A brief 🧵 (carried over from the old place)
Very cool!
Pleased to finally share this fun collab that began at #Ento23
@cedricaumont.bsky.social presented & I had seen NCBI annotated some cockroach genomes as "contaminated." Turns out NCBI & I were wrong (much more fun).

CBASS is a cyclic nucleotide-based antiviral system in bacteria that is related to cGAS-STING signaling in animals. One of the big questions is how CBASS is activated during phage infection? We made some progress on this during my final year in the Kranzusch lab.

Out today: We discovered new viral proteins that target immune signaling molecules, solely based on their AlphaFold-predicted shapes

Congrats Nitzan Tal and coauthors! Thank you Kranzusch lab for the fun collaboration!

#MicroSky Please RT
@erc.europa.eu-funded postdoc position in my lab to identify the molecular basis of prey-predator interactions using our favorite micro-vampire Bdellovibrio exovorus as a model.
Let's find what the bite is made of! 🧛
Flexible start date.

That’s been sent elsewhere where short papers are still allowed! I hate long papers. I really hate long Discussion sections. Get a life!
I still can’t forgive Nature for discontinuing the Letter format
New post-doctoral research position in my phage-host interactions (Phi) laboratory in @otagomicroimmuno.bsky.social at @universityofotago.bsky.social New Zealand. The project is focused on defences against jumbo phages. Please share and if interested apply using the link in the comments.
Phage therapy offers a powerful tool against AMR infections—but only if we move from isolated cases to coordinated systems. The first initiative of the ASM Health Unit, led by Colleen Kraft and Dev Mittar, will tackle this. Delighted by this scientific leadership, join us!

New preprint out on bioRxiv!

Can conjugative plasmids be used to control plasmid and pathogen spread?
Follow me down the rabbit hole that led to this story 🧵

Now out & nicely formatted in @isme-microbes.bsky.social
A big analysis of ocean genomes & metagenomes co-led by former postdocs, now PIs, @gmdouglas.bsky.social & @cyanophage.bsky.social along with co-PIs @lbobay.bsky.social & Samuel Chaffron.
A few highlights... 🧵 (1/n)

Happy 38th birthday to the #LTEE!

Keep on evolving!

Now published: our work using phylodynamics from surveillance data to quantify and experimentally validate the fitness impact of antibiotic resistance determinants & how this changes with patterns of antibiotic use: www.nature.com/articles/s41...
Thank you Mike! I encourage your colleagues to join the new initiative from ASM Health to develop and execute on synergies with phage therapy. Would be great to involve multiple societies and NGO's here as appropriate, as we share common goals.

Thanks for the heads up Vaughn — will check it out and sign up 🙌
Out now in @plosbiology.org : our big joint effort on the role of #CRISPR in plasmid competition. Read on for a really fun (I’m biased ok) analysis of how a defence system has new selective pressures when it’s mobile

Excited to share our new preprint exploring how Paramecium achieves diverse flow functions, i.e. feeding and swimming, simultaneously. This work was spearheaded by our ExM expert, PhD student Daphne Laan @daphnelaan.bsky.social :
www.biorxiv.org/content/10.6...
Up to what degree of interspecific genetic distance is it possible to form viable and fertile hybrids? A strange species of paramecium breaks the record:

Alita Burmeister (@aburmeister.bsky.social) is looking to hire a postdoc (or potentially a PhD student) for projects on phage resistance and evolution. The position description is posted to the Eco-Evo Jobs wiki and also available on her lab's website (arburmeister.weebly.com).
MENI is back! Join us in Dublin this August 2026 for our 3rd Meeting for Microbial Evolution in Ireland. We are delighted to have @rachelmwheatley.bsky.social @drrebeccajhall.bsky.social @jpjhall.bsky.social and @tweethinking.bsky.social join us as keynote speakers this year. miniurl.com/MENI
Cancer therapies exploit DNA repair defects to kill tumours. We asked whether the same logic could constrain antibiotic resistance evolution...

Thanks Zam 🙌
But some ways skin the cat faster and more predictably than others… More on the evolvability of different lineages coming soon(ish)!
Thanks Rich! 🙌
Thanks Jesse!
