We just preprinted DropSynth-Gold where we replaced PCA with Golden Gate Assembly (GGA) inside emulsion droplets, extending multiplexed gene synthesis to ~3 kb constructs assembled from up to 12 fragments while preserving the scalability of DropSynth. 1/n

Our new Science Advances paper is out! 🎉 The Plesa Lab's first, it builds on DropSynth technology as a proof of concept for large-scale synthetic gene libraries, showcasing a synthetic metagenomics approach to studying antibiotic resistance at scale. 👉 www.science.org/doi/10.1126/...

Exploring antibiotic resistance in diverse homologs of the dihydrofolate reductase protein family through broad mutational scanning

DropSynth technology enables scalable and cost-effective exploration of antibiotic resistance across the DHFR protein family.

Huge congrats to Dr. Andrew Holston on a successful PhD defense!! Andrew has been working on the large-scale characterization and engineering of chimeric receptor histidine kinases. He’s looking for roles in biotech/academia, let’s connect if you’re hiring! -> @hkalltheway.bsky.social

Dr. Andrew Holston PhD defense
The Knight Campus at the University of Oregon@uoknightcampus.bsky.social · last yr.

Join us tomorrow, May 23, for Andrew Holston’s PhD thesis defense. Andrew is a graduate student in @calin.bsky.social’s lab, where his research has focused on the large-scale engineering of chimeric histidine kinases. 🧪

Have we hit a "scaling wall" for protein language models? 🤔 Our latest ProteinGym v1.3 release suggests that for zero-shot fitness prediction, simply making pLMs bigger isn't better beyond 1-4B parameters. The winning strategy? Combining MSAs & structure in multimodal models!

Let's talk about how close we are to a cell-free mirror image central dogma in a tube, aka Mirror-PURE! This topic has been getting a lot of attention due to the recent @science.org letter (www.science.org/doi/10.1126/...) outlining the threats posed by mirror life. 1/n
