We (@thomas_day_, @dahaj1897, @dayan1406, @TonyBurnetti, @wc_ratcliff, Stephanie Hohn, and Ray Goldstein) have a new preprint on universal packing statistics in multicellularity. We also explain what multicellularity shares with piles of sand! (1/N) biorxiv.org/content/10.1101/…

Can we witness evolution’s unit shifting from individual to collective, in real-time? @ozan_g_b @wc_ratcliff @YunkerLab evolved large multicellular yeast and said YES! Great fun to spotlight this cool project & its first findings with @orshalevsk @cratzke1. @Trends_Ecol_Evo

Plus I learned the unrelated yet fascinating fact that the reverse of the one cent coin actually shows the Lincoln statue behind the Lincoln Memorial columns... which you can only see if you have the right optical reflectometer in your lab :) Thx @YunkerLab!

Provost @McLaughlin_GT and I had a blast this morning with Profs @wc_ratcliff @YunkerLab + their students, who are answering truly fascinating questions about how multicellular life came to be, how a clump of individual cells can form an organism. Blown away by their work!

#140: Entanglement in living systems @thomas_day_ @dahaj1897 @ozan_g_b @peterlconlin @yunkerlab @wc_ratcliff Unique entanglement, and resulting structural strength, of living systems that grow together, with confirmatory results in snowflake yeast! biorxiv.org/content/10.1101/…

Entanglement in living systems

Many organisms exhibit branching morphologies that twist around each other and become entangled. Entanglement occurs when different objects interlock with each other, creating complex and often...

We have a new preprint, showing that living systems can entangle in ways non-living systems can’t. In non-living systems, entanglement only occurs under specific geometric regimes. Not so for growing systems! Given time, most geometries can entangle. doi.org/10.1101/2023.06.13.5…

Hi folks, we have a new preprint out on the #MuLTEE, examining the molecular basis of multicellular evolution. We found that an ancient protein folding system, Hsp90, can be tuned to drive rapid convergent multicellular evolution. 1/24 biorxiv.org/content/10.1101/…

The yeast went from small microscopic clusters that were 100x weaker than gelatin to blobs the size of fruit flies with the toughness of wood. They’ve started evolving division of labor between their constituent cells, and a kind of circulation. theatlantic.com/science/arch…

One of Evolution’s Biggest Moments Was Re-created in a Year

A unique experiment shows how multicellular organisms might have evolved from single-celled ancestors.

I wrote about an incredible experiment in which microscopic, single-celled yeast evolved to become multicellular organisms visible to the naked eye, recreating one of evolution’s most pivotal transitions in a lab, in just one year. theatlantic.com/science/arch…

I’m delighted that our paper on the Multicellularity Long Term Evolution Experiment (MuLTEE) has, at long last, been published. This paper establishes the foundations of what I’d like to work on for the rest of my career. 1/25 Free, full access link: rdcu.be/dbPA9

Very excited to share our work on autocatalytic self-assembly of RNA and the formation of catalytic reaction networks within the confines of coacervate compartments. Walter Gilbert meets Kauffman + Dyson meets Oparin + Haldane. nature.com/articles/s42004-0…

A journey of a lot of collaboration, hard work and microscope time has just been published in Nature! Congrats to these folks, I am incredibly lucky to be a part of this project. @wc_ratcliff @ozan_g_b @YunkerLab @dahaj1897 and others I missed. Article: nature.com/articles/s41586-0…

De novo evolution of macroscopic multicellularity

Nature - After 600 rounds of selection, anaerobic snowflake yeast evolved to be macroscopic, becoming around 20,000 times larger (approximately mm scale) and about 10,000-fold more biophysically...

Vertical growth dynamics of biofilms | PNAS

During the biofilm life cycle, bacteria attach to a surface and then reproduce, forming crowded, growing communities. Many theoretical models of bi...
