Congrats Joel! Hope all is well with you!

The role of gut microbial metabolites in the T cell lifecycle - Nature Immunology Tran et al. discuss the role of the gut microbiome and gut microbiome-derived metabolites in T cell biology.

Interesting recent review on the links between gut microbes and T-cells, highlighting a mechanistic framework linking microbial metabolites to all stages of T-cell fate and function.

Microbiology professor, want to join a slack for microbiology professors, any career stage, diverse career types (pure teaching, med school, R1, community college, pure research fed PIs, ...)

Message me for an invite link if you are interested.

No imposter syndrome, if you are 1% micro, join!

BREAKING: A federal judge reversed National Institutes of Health's terminations of hundreds of critical research grants that were canceled because of their alleged connection to disfavored topics, including diversity, equity, inclusion, and gender identity.

This is a major win for public health.

Week 19 What now & what’s next in science and higher ed

Each Friday night, I write up what happened in science & higher ed.

- 1200+ pages of new (weird) detailed budget request
- cancellation of pandemic flu & HIV vaccine efforts
- more travel visas throttled
- FEMA, “gold standard science” & more

This was week 19: buttondown.com/liminalcreat...

A designed synthetic microbiota provides insight to community function in Clostridioides difficile resistance Clostridioides difficile, a major cause of antibiotic-associated diarrhea, is suppressed by the gut microbiome, but the precise mechanisms are not ful…

New research from @jordanbisanz.bsky.social et al. used machine learning to design C. difficile suppressive synthetic microbiomes. 🦠

This is a big step towards reducing antibiotic use & making a safer and more effective fecal microbiome transplant alternative.

Metagenomic estimation of dietary intake from human stool - Nature Metabolism Diener et al. present a method that allows the estimation of dietary intake from human stool by detecting food-derived DNA in faecal metagenomes.

Happy to announce that MEDI, our method to quantify dietary intake through metagenomics is out now. 🧬 🧪🧫🦠 www.nature.com/articles/s42...

So what is MEDI? A combination of two things:

Week 3 Figuring out what to focus on now & what to focus on next in science and higher ed

Well. I have been informed that it is the weekend, again.

It’s also okay if you’re coming in hot! “What the actual fuck??” is a sensible start place at the moment.

SAMPL-seq reveals micron-scale spatial hubs in the human gut microbiome - Nature Microbiology Split-And-pool Metagenomic Plot-sampling sequencing (SAMPL-seq) can be applied to complex microbial communities to reveal spatial co-localization of microbes at the micron scale.

Happy to share our new paper in @naturemicrobiol.bsky.social on mapping spatial relationships of the human gut microbiome. We identified distinct spatial hubs between gut bacteria that reflect sub-community assemblies at the micron-scale. Led by Miles Richardson & co.

Today we report a new compendium of human gut microbiomes with >168,000 samples

By analyzing this massive dataset, we discovered distinct microbiome patterns across the globe, and show we can predict where a person lives just from their gut bacteria

We are hiring a new faculty member in my dept at Minn State Mankato! This person will teach human anat/phys for bio majors and run a research program with undergrad and M.S. students. I'm happy to answer questions about what it's like here as new faculty!

✋We're working on some diet-microbiota-immune interactions in multiple sclerosis! Would love to be added - thanks for organizing!

Always notable when the Lamming Lab drops more insight into the geroprotective effects of BCAA restriction. Never thought I’d say isoleucine is the coolest of the 3, but it is clearly super important! 😎 Awesome work!
