Happy to announce that MEDI, our method to quantify dietary intake through metagenomics is out now. 🧬 🧪🧫🦠 www.nature.com/articles/s42... #metagenomics #microbiome #microbiomesky So what is MEDI? A combination of two things:

🧵 The Fight Has Come to Them: Science, Institutions & The Indirects Cut I want to take a moment to talk about the perspective behind these slides I put together. I’ve framed them to be as nonpartisan as possible—but in a moment this polarized, there are limits here. 1/

I’ve unfortunately needed to add more material to my post from yesterday. The re-election of Donald Trump is looking like the biggest act of American self-destruction since the Civil War. Same link, new title and some updates.

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. www.nature.com/articles/s41...

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 Now out in Cell: www.cell.com/cell/fulltex...

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!

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!

Diet profoundly impacts the composition and function of the microbiome having consequences for health and disease. Therefore, it is important to consider diet and the gut microbiome when designing and reporting prebiotic and probiotic clinical trials. See our recent perspectives on recommendations:

Congrats to Min Bae and the Balskus Lab on their new study! Min used a Metatranscriptomics-guided approach to find a microbiome enzyme involved in the metabolism of hydrocaffeic acid. Glad I could be involved in this fascinating study! Check it out here: www.cell.com/cell-host-mi...

Excited to share the final work from my postdoc! We explored how a ketogenic diet improves MS models, identifying bioactive compounds from the host and microbiome. Looking forward to investigating more mechanistic interactions in the Alexander Lab. Huge thanks to co-authors & Peter Turnbaugh!
