02.10.2025 | L’origen de la vida i l’últim ancestre comú, amb Juli Peretó Hui parlem amb Juli Peretó, catedràtic i investigador en evolució, que acaba de publicar un article a la revista Philosophical Transactions sobre un mètode basat en la intel·ligència artificial per re...

🎙️ Ja podeu escoltar l’entrevista a @julipereto.bsky.social, investigador del #I2SysBio, en «L’Hora de la Cultura» d'@apuntmedia.es.

Peretó presenta la investigació publicada a la revista Philosophical Transactions, signada juntament amb @pablocarb.bsky.social.

To save people the reading time: the "some" making this prediction are people who don't understand the limits of current LLM technology and the ones questioning it are people who do. It is, yet again, a "both sides" article where one side has no fucking idea what they're talking about.

Resistance mutation supply modulates the benefit of CRISPR immunity against virulent phages Only a fraction of bacterial genomes encode CRISPR-Cas systems but the selective causes of this variation are unexplained. How naturally virulent bacteriophages (phages) select for CRISPR immunity has...

New preprint!

Ever wondered why only a fraction of genomes encode CRISPR immunity? 🧬 🦠

Turns out CRISPR is rarely beneficial against virulent phages, being most beneficial against those for which resistance mutations are rare!

ggplot2 4.0.0 A new major version of ggplot2 has been released on CRAN. Find out what is new here.

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN.

It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package.

Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

A tu, Toni!

Why has the Dalhousie Board @dalhousieu.bsky.social been using such strange and disrespectful tactics in this labour dispute @dalfaculty.bsky.social ? Is the playbook coming from Nous Group, the consulting company that brought us "Uniforum" and presides over cost-cutting at universities worldwide?

Huge congrats, Megan!!

Huge congrats, Hanneke!! 👏👏👏

I gave a symposium talk at the European Society for Evolutionary Biology 2025 (#eseb2025) meeting last week and this was my title slide showcasing how I was speaking as an independent scientist because @dalhousieu.bsky.social @dalhousie.bsky.social has locked us out.

Getting ready for another semester of seminars for the @eseb.bsky.social STN Internal Conflicts and Organismal Adaptation.

Gràcies a tu, Juli, sempre!

And @tonigabaldon.bsky.social introduced us to the origin of eukaryotes puzzle back in ca 2009. This, and a course by @julipereto.bsky.social, left a mark that stayed with me for years!

Please don't underestimate the importance of inspiring students -- you may influence their entire careers :)

The @uv.es has much to teach us on how to bring cool science to students from top scientists and communicators.

During my studies there, I was inspired every year by the likes of Lynn Margulis, Sydney Brenner, Antonio Lazcano, Mike Lynch, and many others. Definitely made an impact!

Thank *you* Andrew for joining us, giving a great talk, and overall sharing a fantastic week!

Final year PhD students, I know you’re desperately trying to finish experiments/revisions/submissions/write a thesis & just survive - but please spare a few minutes to apply to your dream postdoc labs.

It easily takes A YEAR from first contact, even if everything goes to plan on both sides.

Sam von der Dunk: we know that RNA structure is robust to mutation yet evolvable. What about protein structure? Take advantage of ESMfold https://doi.org/10.1126/science.ade2574
