A tremendous story about a defense system that triggers plasmolysis! It was an incredibly exciting puzzle to crack. Huge thanks to @fnobrega.bsky.social for the opportunity to work on this!

Made a short video as a response. 3 questions remain for me.
1) What is the definition of a "DEl activity," and how is it being communicated to NIH staff so they can determine whether a grant qualifies?

β‘οΈ preprint from the lab! Bacteria have loads of antiviral defences in their mobile genetic elements (MGEs). So when MGEs move between bacteria, the defences move with them, generating a fast turnover of defences in bacteria. But what about the antiviral defence turnover in the MGEs themselves? π€

Spatial structure: shaping the ecology and evolution of microbial communities
Spatial structure naturally emerges in microbial communities, shaping growth, interactions, and evolution, and revealing how microscale processes scale up
Most microbes don't live in shaking flasks; spatial structure shapes how microbes interact and evolve at every scale, as we discuss in our recent review @jeroenmeijer.bsky.social @simonvanvliet.bsky.social @bedutilh.bsky.social @bramvandijk.bsky.social and others

Instead of forcing structures into rigid classifications, we built AFragmenter. It uses AlphaFold PAE networks for a tuneable approach to domain parsing.

Python is not a great language for data science. Part 1: The experience
It may be a good language for data science, but itβs not a great one.
I've done a lot of work in Python this fall, and it hasn't endeared me to the language at all. Why does stuff have to be so complicated when you're doing it in Python?
