I know it seems like a heretical idea, but one way to figure out if a preprint is really interesting (to you) is... to read the preprint. Then, in the spirit of sharing, send a note to authors: a simple kudos or a more detailed question. I do this a dozen times a year. It's awesome. Try it.
🚨 Abstract submission deadline is approaching for #EMBOEvoEco! If you want to be part of the EMBO Workshop focusing on uncovering the mechanistic foundations of ecological and evolutionary processes. Submit your abstract by 30 June: https://s.embl.org/eae26-01-bl
Researchers selected yeast cells for small size for 1,500 generations, achieving a fourfold modal volume reduction, and identified mutations in nutrient-sensing and cell-cycle pathways that enabled shrinkage while maintaining relatively high fitness. In PNAS: https://ow.ly/zezn50ZcU0y

🗞️ New preprint from the lab, led by our postdoc Ana Garoña (not on here) in collab with @andreagiometto.bsky.social: “Experimental evolution of cellular miniaturization reveals a mechanism for cell size evolution”, aka: “honey, we shrank the yeasts!” 🎥 www.biorxiv.org/content/10.6...
A few snapshots from the @embo.org workshop “The Rules of the Game: biophysical and molecular principles in cellular evolution” — and an excuse to thank everyone who made it such a fun, stimulating, and inspiring few days at @gimminstitute.bsky.social #EMBORulesOfTheGame
How do we fund and publish research that doesn't fit neatly into a single discipline? Last week, at the #EMBORulesOfTheGame, #HFSP Chief Scientific Officer Guntram Bauer presented how HFSP supports #frontierscience across disciplines and borders. @embo.org

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)
A study in Nature shows that the single-celled form of a tiny, aquatic organism can turn into a multicellular version by three different routes. The discovery adds insight to the possible origins of multicellular life, suggesting a previously unrecognized degree of flexibility. 🧪
EMBO was part of the group that developed DORA's new introductory course on #ResponsibleResearchAssessment. 🧪 We’re pleased to see its launch, more info here: https://sfdora.org/2026/02/23/new-introductory-course/
Fostering Responsible Research Assessment: DORA Launches New Introductory Course | DORA
DORA is delighted to announce the launch of its Introduction to Responsible Research Assessment (RRA) Course. This online, self-paced course provides an approachable, entry-level curriculum for anyone at any career stage and in a variety of roles to learn about RRA. While the course is free for individuals to take, it requires registration, and provides the option of issuing a certificate for each of its four lessons and one for its full completion.

How do new centromeres evolve while staying compatible with the division machinery? Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore. 👉 doi.org/10.1038/s41586-025-09779-1

I'm curious if other mid career PIs have considered completely abandoning the trad publication model. We've been making gradual moves towards that end goal. But it's been difficult to completely jump ship for one main reason for me at least. 1/
