2 flight cancellations later I am on my way to Evolution 2026! I've never been to this conference before but I am very excited I was invited to speak, the whole program looks great! This is a bit outside my usual network, hit me up if you want a buddy for coffee or meals 😁 #evosky #MEvoSky

Why has nobody connected the fact that Trump roped off the entire national mall to create a stupidly perfect lawn to the bloom in the reflecting pool? (Was there two weeks ago for ASM)

Now there's TWO recent preprints on 16S primer choice! V4-EXT (V4 with broader diversity?) JEDI (V4-V5 validated for 18S as well?) Haven't wrapped my head around which is which and they're both brand new so no in-paper discussion (ppr links below)

What percent reads mapped to MAGs is "good" for soil or sediment samples? is lower than water samples OK/expected due to more complex communities? 🙏 🖥️🧬 microbiome, metagenomics

I love data.table so so much more than tidyverse. #rstats Here's an example, similar length but count the total functions outside of core syntax: dplyr: 10 group_by(), summarize(), sum(), arrange(), desc(), slice_head(), pull(), mutate(), ifelse(), %in% data.table: 3 sum(), order(), %in%

it's an image of side-by-side code to do a simple task of pulling out the top 3 phyla and combining the rest into an other category. dplyr on the left uses of course all the piping syntax, and data.table uses all the bracket syntax. They're about the same length, but for dplyr you have to remember so many distinct function names.

It has been amazing to continue this long-term research through a PhD with @quendi.bsky.social and a postdoc with @archaeal.bsky.social . Not everyone gets to see a project through like this as an ECR- thanks to supportive PI's and the NSF-PRFB fellowship that let me design my own postdoc 💙🧪

After 24 years of work, I’m thrilled to announce the TYMEFLIES dataset, which comprises metagenomes from Lake Mendota (Madison, WI), collected roughly every 10 days (471 samples) for 20 years! @quendi.bsky.social @robinrohwer.bsky.social rdcu.be/d5put A thread…

A great welcome back to work after the holidays! This is my first Nature-family paper and I really liked their publishing model with a supportive, involved, full-time editor. You can see how this paper developed on bioRxiv and in the public review documents 📝 @naturemicrobiol.bsky.social

Trying out anvi'o for the first time (!!somehow!!), but I can't find any details on the methods underlying these functions. Like anvi-refine clusters your contigs... based on.. what vectors? what distance? is everyone just using these methods blindly or am I missing something? 🖥️🧬 #microbiome
