I am excited to share our latest paper, Uniform bacterial genetic diversity along the gut, now out in Nature Communications! www.nature.com/articles/s41.... (1/n)

So excited to have this study live! Lead by @ee-reh-neh.bsky.social's teram and in collaboration with an incredible team at MRIN in Indonesia. This is the culmination of ~5 years of work including a ton of effort in the field. Really proud of how this came together!

Intracellular competition shapes plasmid population dynamics From populations of multicellular organisms to selfish genetic elements, conflicts between levels of biological organization are central to evolution. Plasmids are extrachromosomal, self-replicating g...

Hot off the press! Our latest paper led by @fernpizza.bsky.social, understanding how plasmids evolve inside cells. These small, self-replicating DNA circles live inside bacteria and carry antibiotic resistance genes, but also compete with one another to replicate. 1/

Selection and transmission of the gut microbiome alone can shift mammalian behavior Nature Communications - Here, the authors present evidence that the gut microbiome alone, without changes in the host genome, can shape how animals respond to selection, identifying a bacterium and...

We selected the laziest mouse at each round to inoculate the next batch of germfree mice: over rounds of selection and passaging, behavior shifted without changes to the mouse genome: rdcu.be/eM3rO

Gut fungal profiles reveal phylosymbiosis and codiversification across humans and nonhuman primates Fungi in the gut microbiome (the "mycobiome") are a neglected component of the human holobiont. This study of gut fungal profiles across natural populations of humans and non-human primates reveals si...

The gut MYCOBIOME is akin to the tiny group of kids in the corner of a huge homecoming dance. Their story is largely unknown. In our latest, @emilyvansyoc.bsky.social dives into the evolutionary associations of gut fungi with @erdavenport.bsky.social & Andres Gomez

journals.plos.org/plosbiology/...

Human fungi-associated variants (FAVs) associate with 9 fungal taxa and overlap protein-coding genes. A Manhattan plot shows all FAVs and their associated fungal taxa at the three significance levels (exploratory, black; genome-wide, red; study-wide, blue).

What determines the human gut fungal community? @emilyvansyoc.bsky.social @erdavenport.bsky.social @symbionticism.bsky.social &co present the first #GWAS of human genetic loci that influence the abundance of gut #fungi, linking these to disease risk #mycobiome @plosbiology.org 🧪 plos.io/42bCKou

Gut fungi are associated with human genetic variation and disease risk In contrast to decades of research on gut bacteria, human genetic determinants of the gut fungal community (mycobiome) remain understudied. This investigation presents the first GWAS on the number and...

We published a new lane of research today on human gut fungi. Shout out to 1st author @emilyvansyoc.bsky.social sky.social & @erdavenport.bsky.social For 20 years, bacteria received the lion's share of interest in the human gut. Yet we know little about the gut mycobiome. doi.org/10.1371/jour...

A screenshot of the termination notice with "This award is terminated effective the date of this award, due to unsafe antisemitic actions that suggest the institution lacks concern for the safety and wellbeing of Jewish students." highlighted

Yesterday, the NIH R35 “Outstanding Investigator” grant to fund scientists in my lab studying antibiotic resistance was terminated for reasons not related to the content of the science, or any actions taken by me or members of my lab

Such bullshit. I’m so sorry you’re dealing with this
