Our paper "Gene ancestries reveal diverse microbial associations during eukaryogenesis.” is finally out in Nature. Eukaryogenesis was likely a gradual process shaped by multiple microbial partners and virus-mediated gene transfer, rather than a single binary symbiosis. doi.org/10.1038/s415...

🦠 How did our cells originate? A study by @gabaldonlab.bsky.social at @irbbarcelona.org & @bsc-cns.bsky.social suggests cellular complexity emerged gradually over millions of years, rather than from a single evolutionary event. 📝 Published in @nature.com #BISTCommunity 👉 bist.eu/a-study-by-i...

Monday 15th of June at 12:30 I will be giving a talk at the Faculty of Sciences of #Tetouan (Morocco). I will be talking about our recent work on the emergence of drug resistance and new pathogenic species from environmental sources in #Candida related yeasts.

Very proud of Islam, who performed part of her thesis with us at @irbbarcelona.org . Has been a pleasure to attend the defence, and has been my first chance to visit Morocco.

Congratulations to our new Doctor, Islam Ahaik who obtained her PhD today at the Faculty o Sciences in Tetouan.

Gene ancestries reveal diverse microbial associations during eukaryogenesis Fantastic paper from @microbiobits.bsky.social @tonigabaldon.bsky.social and colleagues. www.nature.com/articles/s41...

This theoretical approach (previously in this @pnas.org s.org paper by @nigelgoldenfeld.bsky.social and Carl Woese www.pnas.org/doi/abs/10.1...) seems consistent with the recent work by @tonigabaldon.bsky.social on the complex paths towards the emergence of LUCA.

I si l'origen de les nostres cèl·lules no és com ens pensàvem? 🦠🤔 Un estudi liderat pel #RecercaireICREA @tonigabaldon.bsky.social (@irbbarcelona.org @bsc-cns.bsky.social) ha descrit el rol de bacteris i virus gegants en l’origen de les cèl·lules complexes. 👇🏼 www.lavanguardia.com/ciencia/2026...

How did complex cells emerge? In this groundbreaking paper, @tonigabaldon.bsky.social & co show that eukaryotes arose through multiple waves of ancient genetic exchange involving diverse bacteria (& giant viruses!) revealing a far more complex origin than we imagined. www.nature.com/articles/s41...

Y si la aparición d las células eucariotas no hubiera sido tan sencilla como pensábamos? Gran trabajo @tonigabaldon.bsky.social 🙌🏻🙌🏻🙌🏻🥂🍾 www.expansion.com/directivos/e...

Funny to get quoted on a pun about the origin of eukaryotes being a bit of a promiscuous relationship in the 🇪🇸 press, but glad to help communicate @tonigabaldon.bsky.social & his team's fatnastic work, which highlights the importance of giant viruses 👾 in eukaryotic origins @nature.com. Congrats!

🦠Un estudio español en @Nature replantea el origen de nuestras células como una historia de alianzas microbianas 🗨️Alex de Mendoza: "El proceso de formación de los eucariotas no fue una relación monógama de dos organismos, sino más tipo ménage à trois" sciencemediacentre.es/un-estudio-e...

"Thus, the prokaryotic-to-eukaryotic transition was probably a gradual and complex process, with a constant flow of HGT from diverse sources." #SymbioSky

🦠Los restos de Ötzi, el ‘hombre de hielo’, albergan microorganismos modernos y antiguos 🗨️ Toni Gabaldón: "Los microbios, incluidas las levaduras, se abren camino en ambientes tan extremos como las temperaturas por debajo de 0" sciencemediacentre.es/los-restos-d...

Fantastic paper. Esp challenging the typical binary process of genesis or transition. Just as the first cells as we know them were possibly survivors of multitudes of attempts that did not survive to evolve. The origin of cellular life was not simple; neither was evolution to multiple cell types.

The origin of complex cells may have been far messier than we thought!

"Entender el origen de la vida nos ayuda a explicar el mundo en que vivimos, incluida nuestra propia existencia", dice @tonigabaldon.bsky.social, autor principal del estudio. También impulsa otras investigaciones y abre la puerta a "posibilidades que no imaginamos". Los superordenadores ayudan 💻 🦠👇🏼

Una investigación fundamental sobre el origen y evolución de la vida. La investigación básica - apoyada en la supercomputacion- entra en temas que parecería imposibles abordar hace unos años. Bravo por Toni y su grupo!!

No wonder it’s complicated to understand immune responses. We are part bacteria part virus too, more than we thought! Congrats superToni and Gabaldón lab

1/7 We often picture eukaryogenesis as a symbiosis between two lineages: an archaeal host & the ancestor of mitochondria. But what if the origin of eukaryotes emerged within a much more complex microbial ecosystem? A fascinating study from @tonigabaldon.bsky.social et al. explores exactly this. 🧵

¿De dónde venimos? El gran salto evolutivo del que surgieron las células complejas que nos conforman es un enigma. Un estudio de @irbbarcelona.org y @bsc-cns.bsky.social revela que hay más actores implicados de los que pensábamos El 'ménage à trois' celular 👉 www.elconfidencial.com/tecnologia/c...

Doing a PhD is not simply generating data. It’s learning how to be a scientist. It’s teaching and science communication, and writing, and presenting and FUCKING THINKING.

Possibly the best way to phish academics would be to just send them email that looks like a request to review an article and embed your malware in the "decline to review" link

I’ll be participating this year. Discussing the wonders of DNA sequencing over a “scientific coffee” with interested citizens. Come and join us!

Once more our group was present in the nice FEBS advanced course #hfp2026 at La Colle. With presentations and posters by @tonigabaldon.bsky.social Mrina, and Vlad. As always the conference was great! Thank you to the organizers!

Interested in Asgard archaea? @tonigabaldon.bsky.social and I wrote a small blog post on our most recent paper about these fascinating group of prokaryotes and their genome dynamics: go.nature.com/4uPLY5W

Was a pleasure to participate as an invited speaker at the 7th retreat of the Biology Dept of university of Padova!. This have me the chance to visit the oldest preserved botanical garden.

#paper Echinocandin-resistant Nakaseomyces glabratus can retain fitness across host niches. This could help explain breakthrough infections. FKS requirements are niche-specific: FKS1/FKS2 support gut colonization, while FKS2 is key for systemic infection. journals.asm.org/doi/10.1128/...

#ESCMIDGlobal2026 is over. The group participated with oral presentations from Hrant Hovhannisyan (computational multiplexing optimization) and @tonigabaldon.bsky.social (evolutionary genomics of #Candida ), there was a lot of learning and networking.

📣 EvolDir is now managed by @eseb.bsky.social! We are delighted to be taking the reins and express our gratitude to both Brian Golding who began this service to the community in the mid-1980s and to @rdmpage.bsky.social who ran this account until now 👏 You can now find evoldir here: evoldir.net

This is the cool stuff: phage steering - using phages to force evolutionary trade-offs in pathogen! Sounds a bit Science-fictiony but there's now clinical studies on small groups of patients! #ESCMIDGlobal2026
