I didn't want to re-install a bunch of software in the new year, but at least the anvi'o messages will keep me entertained (thanks, @merenbey.bsky.social and others)!

This reminds me of the poem Melinda Mae in "Where the Sidewalk Ends" where the little girl eats a whole whale.

We just submitted a manuscript for review with a "we can't get our data approved in NCBI so please believe us that we will upload it" apology note in the methods section. 😐 (which is so minor compared to what other folks are dealing with)

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 love all of this but especially that you've made anvi'o databases (I may or may not have been contemplating how long it would take me to do that for the GTDB database this week).

oooh, I like this! I like MRA too (its such a smooth publication process). @titus.idyll.org might also have some ideas on where else folks publish this type of work.

Trump memo to halt federal funds triggers confusion and constitutional questions Washington is scrambling to interpret a new Trump administration memo that appears to halt funding for many programs. The impact of the short memo, released Monday, is causing widespread confusion.

NPR also had a nice piece on it this morning. I think this is the "print" version of that www.npr.org/2025/01/28/n...

NSF cancels grant reviews to comply with Trump EOs Scheduled review panels for National Science Foundation grant applications are on pause until Feb.Β 1. Some researchers believe the pause may be connected to the new administration’s anti-DEI crusade.

www.insidehighered.com/news/governm... this article may be helpful (in the middle to bottom). As I understand it, this is proposal review and outgoing awards (I *assume* if the money is in hand already, you can continue you work, but that is an assumption on my part)

You should get a text when yours is received and counted! (though maybe If you mail it later in the cycle it may be after the race is "called" - especially in CA - but it still counts)

Physiology, Not Nutrient Availability, May Have Limited Primary Productivity After the Emergence of Oxygenic Photosynthesis The evolution of oxygenic photosynthesis in Cyanobacteria was a transformative event in Earth's history. However, the scientific community disagrees over the duration of the delay between the origin ....

Do we brag on this thing (or did we leave that behind in the other place)? Because Dawn Sumner and I wrote what I think is a pretty cool perspective on why we should consider ecology and evolution when discussing early oxygenic photosynthesis and the GOE. tinyurl.com/mwsdras5
