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.

Doing a lecture on why it's important to be good at science communication/why it's important to communicate science in plain English on the day when we find out that there's Whooping Cough on campus.

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

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 ....
