Happy to share the Biodiversity Cell Atlas white paper, out today in @nature.com. We look at the possibilities, challenges, and potential impacts of molecularly mapping cells across the tree of life. www.nature.com/articles/s41...

For some three billion years, unicellular organisms ruled Earth. Then, around one billion years ago, a new chapter of life began go.nature.com/3JyRV4S

Adaptive radiation during long-term experimental evolution of the multicellular bacterium #Streptomyces www.biorxiv.org/content/10.1...

Excited to share new #program, STEPS, which can simulate #dynamics of the E. coli Long-Term Evolution Experiment (#LTEE) or other microbes in serial transfer regime. telliamedrevisited.wordpress.com/2025/08/12/s... STEPS developed by @devinmlake.bsky.social, Zachary Matson, Minako Izutsu, and me.

Introducing the 1,000 Flower Collection 🧬🌹 I’m creating 1,000 genetically designed flowers each crafted with new colors, patterns, and shapes. Here’s how I’m making it happen… and how you can join me on this journey 🧵(1/7)

Online now @ Cell is the yeast multicellular engineering paper from Fankang Meng - the fruits of his productive PhD in our group. He developed modular synthetic biology tools to bring multicellular behaviours to yeast - specific adhesion, juxtacrine signalling and more. www.cell.com/cell/fulltex...

1/27 We have a new paper out! Turns out that snowflake yeast have been hiding a secret from us - they've evolved a (very!) crude circulatory system. Not with blood vessels or a heart, but through spontaneous fluid flows powered by their metabolism. 🧪🔬 www.science.org/doi/full/10....

I’m very excited to share our work on the early evolution of animal regulatory genome architecture - the main project of my postdoc, carried out across two wonderful and inspirational labs of @arnausebe.bsky.social and @mamartirenom.bsky.social. www.nature.com/articles/s41...

Fun Q&A with Curr Bio in which I discuss mammoths, Don Quijote, and why you should not fall in love with a hypothesis authors.elsevier.com/a/1l2MF3QW8S...

Sign ups for the fall Barcelona multicellularity meeting are now up- come join us! meetings.embo.org/event/25-mul...

We published a new xenobot-related paper today: journals.plos.org/ploscompbiol... In a nutshell: building xenobots from frog "explants" is good because explants, apparently, come with adaptive potential "built in". This paper took 6 years and 10 co-authors (see post #2) to reach the light.

Contrary to popular belief, what is important in science is as much its spirit as its product: it is as much the openmindedness, the primacy of criticism, the submission to the unforeseen, however upsetting, as the result, however new that may be. – Francois Jacob www.nature.com/articles/s41...

Striking new study from @archaeon-alex.bsky.social's lab just out in @science.org on multicellular development induced by compression in Archaea: www.science.org/doi/10.1126/...

My new paper examining how plasticity may have shaped the evolution of cellular differentiation is out! We propose that the plastic development of somatic-like cells may have been an intermediate step in the evolution of soma in the volvocine algae. #evosky #mevosky doi.org/10.1098/rspb...

This "behind the paper" is a pretty fun read. Kai includes discord chats and other pieces of day to day science that do a great job of showing how the paper came together.

1/46 Hey folks, we have a new paper out on the MuLTEE. Strap in and I’ll tell you the story of how this “little paper on polyploidy” turned into the most data rich paper our lab has produced, largely thanks to the leadership and work ethic of @kaitong25.bsky.social. www.nature.com/articles/s41...
