I can confirm - very nice folks at UC Davis! Come join us!

I really like this framework! There's a similar issue with psychrophiles vs. "can survive in the cold but would prefer to be a bit warmer if possible"

In my experience it's super common just to see a university. Sometimes searching scholar for the bioproject number can get you there (yours is this paper www.nature.com/articles/s41...) but it is a hard/annoying thing to do at the scale you all work at!

Wawa is fighting on two fronts?! I don't think I've ever seen Royal Farms. I'll have to visit one on my next trip that direction. Happy field-working!

Well, I guess we know where you stand on the Wawa vs Sheetz debate (but seriously, enjoy the delicious hoagies!)

I'm officially really jealous of this - my coaches insisted of classical (read - really old) music. But I did end up with Fossils (from Carnival of the Animals) so, I guess it turned out okay.

I'm happy to announce the latest release of the GlobDB, available at globdb.org. The GlobDB is a database of "species dereplicated" microbial genomes, and as of release 226 contains twice the number of species-representative genomes (306,260) than the latest GTDB release.

I think Writing Science in Plain English by Anne Green has a decent chapter or two on this. I can't find my copy now but the very last of these slides from the Dessimoz lab suggests that my memory is at least somewhat true (lab.dessimoz.org/teaching/rqb...)
