I'm very happy to share our latest manuscript published today in @nature.com !! ➡️ doi.org/10.1038/s415... We analyzed data from over 34,000 participants in the US and UK, revealing strong associations between specific gut bacteria and markers of cardiometabolic health and dietary habits.

1/9 Metagenomics lets us read microbiomes in nature without cultivation, but writing (editing) them in their native context is still a major challenge. Meet MetaEdit: a platform for pathway-scale metagenomic editing inside the gut microbiome. science.org/doi/10.1126/...

Metagenomic editing of commensal bacteria in vivo using CRISPR-associated transposases
Although metagenomic sequencing has revealed a rich microbial biodiversity in the mammalian gut, methods to genetically alter specific species in the microbiome are highly limited. Here, we introduce ...

New #preprint from the lab! Do you want to see the invisible? So did we! When DNA genomes get broken, cells somehow find related sequences to fix the break. But how do they find it? We developed a way to look at sequence *search*, not just sequence usage. doi.org/10.1101/2025...

Coffee consumption is associated with the presence and abundance of a specific member of the human gut microbiome, Lawsonibacter asaccharolyticus, and changes to the plasma metabolome, according to a paper in Nature Microbiology. go.nature.com/3CIl4as 🧪
This is figure 1, which shows the consistent global links between coffee consumption and the human gut microbiome.
