This started in 2019 as daydreamy PhD student musings with Tatsuya Araki. We're as excited as ever about germinal centers as a platform for experimental evolution. Many thanks to PIs @victora.bsky.social @matsen.bsky.social, co-1st authors Ashni Vora and Tatsuya, and many other key collaborators!

Replaying germinal center evolution on a quantified affinity landscape
Antibody affinity maturation results from a somatic evolutionary process that takes place in the germinal center. A “parallel replay” experiment on germinal center B cells reveals the evolutionary for...

I've been getting questions about this paper all week: www.cell.com/cell/abstrac... They make EXTRAORDINARY claims - fortunately, these are trivial to verify/falsify. Unfortunately, there's other concerns.

Hot off the press! Our latest paper led by @fernpizza.bsky.social, understanding how plasmids evolve inside cells. These small, self-replicating DNA circles live inside bacteria and carry antibiotic resistance genes, but also compete with one another to replicate. 1/ www.science.org/doi/10.1126/...

So awesome to have this great paper from Sam Reffsin and Sara Cherry out! In it, we use retrospective clone tracing to show that there are particular single cell states that are more susceptible to viral infection (both SARS-CoV-2 and flu)! www.cell.com/cell/fulltex...

To dissect the gene regulatory networks used to build organisms, we need Perturb-seq-like tools that work in whole animals. For this purpose, we developed MIC-Drop-seq, a tool that couples high-throughput CRISPR in zebrafish embryos with single-cell RNAseq. www.biorxiv.org/content/10.1...

Pooled perturbation screens can reveal cellular regulatory networks, yet scaling these techniques for large-scale screens in animals remains challenging. To address this, we developed MIC-Drop-seq, wh...

A few final comments on this because it's such a perfect example of how conspiratorial thinking gets completely off the rails, when much more mundane and simple explanations exists. Below, I'll go through the main "Origin" sections, briefly, but let's first address the main question... 🧵👇
