New "Fidelity" #rstats package release with Abbey Neat can
quantify and compare the specificity of #microbiome communities associated with certain hosts or groups!

It intelligently handles rare taxa removal.
And check that handcrafted hex sticker! 😍

Lovely visit to U of Maine. Great folks and fun conversations about microbes!

COVID vaccine gun show!
(Yeah I have asthma, diabetes, a weak heart, smoke 3 packs a day, or whatever lies you have to tell to get preventative medicine)

10 years using Ubuntu and other linux distros and I JUST NOW learned that you can mount any server address in the file browser so easily!?

Wow, that editor really used the desk-rejection of my paper to channel some of their disappointment and anger. I hope they feel better soon. We're all on the Titanic together.

Y'all, I just did this and it was total bliss, a terrifyingly immersive write-a-thon, full of excellent people, massively educational... And I wrote a whole-ass draft from scratch! 5 stars.

Come check out my talk today (last slot of the agro-eco session) to hear about restoring soils #MSAFungi25

#MSAFungi25 off to a great start. Too many cool sessions to choose from so I might just sit here instead

Coastal Virginia is so hot and muggy my legs are sticking together and I could.not.be.happier after the "longest winter of my life!"

How ugly can you make a fasta file?
Collaborator gave our class a fasta in a word doc, so we're returning our gene predictions similarly!

The Zahn lab is transitioning into the TIDAL Lab this Fall and moving to the Appl. Sci. Department at William & Mary.

Would love to chat with students interested in doing a PhD at the nexus of microbial ecology and data science (starting 2026).

RP please!

Learning so much at "spore camp" with @balachaudhary.bsky.social
Check out these AM #fungal spore micrographs. What bacteria are lurking in the sporosphere #microbiome?

Rauner special collections library at Dartmouth has given me two life dreams come true. Today I finished reading "Origin" from a historic first edition, along with an original Sherlock Holmes!

Had a great time giving a seminar about #microbiome transplantations at Ohio State.
