Huge congratulations to Dr. Arya Kaul on his successful thesis defense today! The fourth from my lab


this morning, while taking my golden retriever for a stroll, i walked past a middle-aged man wearing a sweatshirt that read in big bold print “never stop being kind to people.” i smiled and said “good morning” to him. he looked at me like i was an alien, said nothing, and kept walking. i’ve been thinking about this all day. i think it is the perfect metaphor for modern life.




🎉 New year, NEW PREPRINT! Bacteria exhibit astonishing genetic diversity, but where do new genes come from? My best friend Arya Kau (/labmate in the @baym lab) investigates how advantageous deletions can spawn new genes - "deletion-born fusions." 🧵:


What is the best strategy to win any contest? Eliminate your opponents of course. Recently, my colleague @fernpizza showed how plasmids compete intracellularly (check out his paper just published in Science today!). Together with @baym, we now know how they can fight.

What was antibiotic resistance like before we ever used antibiotics? How did we change what antibiotic resistance genes looked like over 100 years? Our paper looking at genomes from the NCTC historical collection now out in : microbiologyresearch.org/content/journa…

Llamas, dolphins and measles? Oh my! So thankful this story is finally breaking containment from my time in the @MangusoLab. Using pieces from viruses and llamas we engineered selective cell specific viral like particles with reduced immunogenicity for in vivo gene delivery

So happy that I can finally share the results of my first postdoc paper with @baym!! Turns out plasmids are an amazing system to study multi-scale evolution and we can track within-cell and between-cell dynamics! Here’s a photo of plasmids competing inside cells in a colony (1/n)






Being in the training data is useful. A few of the LLMs do a good “explain this like Ethan Mollick” - not nearly as good as me (in my opinion) - but kind of neat to see a form of intellectual legacy happen in real time.






Imagine you’re a plasmid conjugating into a recipient cell. How would you overcome CRISPR-Cas and other bacterial defense systems? Encoding anti-defense mechanisms is one obvious way. But where? And how? @BruriaSamuel set out to explore! 🧵 1/6 biorxiv.org/content/10.110…
