Pretty science and pretty colours is a combination hard to beat
With this working, as a first test we took two plasmids, identical save for 8 point mutations changing the color, and competed them against one another. Here’s a video of what it looked like when we activated the recombinase. You can see the two compete in real time: 4/

Now that we understood neutral dynamics, we turned to competition. What could cause one plasmid to replicate better than another? Our first thought was transcription might interfere with replication, and it turns out there was a much larger tradeoff than we expected! 7/

The proliferation of SUVs is one aspect of “carspreading,” whereby cars are becoming steadily larger over time and with this comes potential harms to health 🧵

Bacteroides Theta-Iota-Omicron is polymorphic already in its name. What are the differences between the morphotypes? We tried to answer this with a combination of mechanical separation of cells based on their shape and an ultra-low input RNA-seq protocol. Paper from @elisebor.bsky.social here 👇

Did you think you needed a promoter for CRISPRa? Think again!
6/10 dCas12f-Sigma factors are able to recruit their native RNA polymerase (RNAP) to drive RNA-guided transcription at programmable sites. Remarkably, we were able to generate RNA (see RNA-seq) without relying on promoters in intergenic sequences, even within genes, and on either DNA strand.
