This is where I live! Obviously I can't vote, but I will be looking very expectantly for the results on Tuesday!
Y'all, this race is going to come down to who shows up at the polls. Trump carried this district by 22 points, and @aftynbehn.bsky.social is within 2 points in this poll!
If you live in 7, GO VOTE! Today is the last day of early voting, or you can vote on December 2nd.

Brand new preprint from my lab, showing that TnpB, the ancestor of Cas12, acts as a gene drive in plasmids! And it turns out in conjugative plasmids that it acts as a primitive anti-self defense system, providing a potential link between its transposon effect and becoming CRISPR!
What is the best strategy to win any contest?
Eliminate your opponents of course.
Recently, my friend @fernpizza.bsky.social showed how plasmids compete intracellularly (check out his paper published in Science today!). With @baym.lol, we now know they can fight.
