Our new paper in @natcomms.nature.com is now online-early! We describe independent evolution of bacterial genomes of only ~50–52 kb — the smallest known outside cellular organelles — revealing striking convergence toward minimal gene sets. 🔗 doi.org/10.1038/s414...

Niche #microsky question: if you have a Cerillo microplate reader in a shaker, how reliable is it? Do you have issues with OD reading stability? Would you recommend if there are issues with false high OD due to aggregation? Pls share! Thanks!

Announcing our next #NSFfunded workshop on "Telling Stories Through Data", co-lead by myself + @vgwschutte.bsky.social! It’s half bioinformatics data viz & half #SciComm - this year’s focus is host-associated microbiome datasets. Apply here to join us (form closes 1/10) bit.ly/TSTD2026 #symbiosky

How host and symbiont cells interface in intimately symbiotic associations is still poorly undersood. @annazaidmanremy.bsky.social and her team @inrae-umr-bf2i.bsky.social identifed now a complex network of membraneous tubules containing carbohydrates presumably feeding Sodalis symbionts of weevils!

FISH images of microbial cells in host organs/ tissues sometimes remind me of Van Gogh's starry night. Am I the only one? No? Yes? Maybe? Anyways, I just wanted to recreate it ;) #microbiomesky #microbiome #art

The 2nd edition of Comprehensive Molecular #Insect Science is out. As section editor for #Immunity and #Symbiosis, I had the privilege to work with outstanding contributors. Other sections cover #genomics, #physiology, #neurobiology, and #ecology 🔗 www.sciencedirect.com/referencewor... #SymbioSky

Hi! Florence Hommais, @nicolasparisot.bsky.social , and I are looking for a postdoctoral candidate to investigate the molecular dialogue between three weevil species and their endosymbiotic bacteria #symbiosis! Please see the #post-doc offer for more information. #SymbioSky #Bioinformatics

Had to draw a cartoon for this fascinating finding! Defensive fungal symbiosis on insect hindlegs: www.science.org/doi/10.1126/... #SymbioSky

A long, long time ago, we started this review project during the first Coron lockdown, but if finally made it out into the world - Origin and function of beneficial bacterial symbioses in insects! @naturerevmicro.bsky.social

Working on a little educational/sci-comm project about microbial life and symbiosis 🦠🧫 Pls share and send me your favorite and most interesting symbiont or pathogens from any form of life :) 👽 Happy to acknowledge all of your contributions! 🥳 #MicroSky #SymbioSky

Hi! I'm restarting my project to cartoon and post about cool animal - microbe symbioses. First up, Burkholderia bacteria, the symbiotic "superheroes" of Lagria beetles. I did my PhD work on identifying mechanisms that help this ectosymbiont establish in the host :) #SymbioSky

#SymbioSky a great continuation of the story from takema fukatsu's lab that STC reported on earlier > schaechter.asmblog.org/schaechter/2... journals.asm.org/doi/10.1128/...

Reposting for #SymbioSky, originally from @tcsengl.bsky.social. Symbiosis in context: Connecting insights across systems and scales When? 7th-10th October 2024 Where? Rothenburg Germany Some of the invited speakers in here @jillianmpetersen.bsky.social @keyfm.bsky.social

We have an opening for a PhD student in my group. Project: Understanding the mechanisms of synergistic coevolution. Approach: Coculture experiments, microscopy, analyses of fitness/ mutational effects. Deadline: 28.07.24 Please RT More info: shorturl.at/5ZP7R

Did you have no chance to attend a symbiosis conference this year in Europe or are you already looking forward for the next one? Then join us in Rothenburg o.d. Tauber this Oktober. We cover a wide spectrum, parasitism-mutualism, plants, animals, MOs, terrestrial & marine... x.com/SymbioseCont...
