Can someone who knows this stuff better than I do tell me if Trump’s new $100K H1-B rule applies to non-profits/Universities? I’m assuming no, but probably shouldn’t be assuming anything reasonable anymore.

🚨While the world is burning down around us, I'm happy to share that I've been promoted to Associate Professor with tenure. Though this is considered a personal achievement, it was only possible due to the wonderful trainees in the lab, who carried me here❤️.

This is unacceptable. A total disgrace. Shame on the organizers. Leave science out of it! I am appalled to see this in the microbiology community 🦠

This is the kind of paper we should all be waiting for!

Because sadly we still don't have reliable methods to count bacterial abundance from microbiomes.
