New preprint out! Using ~75k environmental OTUs + 77 fossil calibrations, we reconstructed a Proterozoic timeline of eukaryote evolution. Our results show crown eukaryotes were already diversifying >1.6 Ga, long before the first undisputed fossils (~1.05 Ga). 🔗 DOI: www.biorxiv.org/content/10.6...

Excited to share the final version of our study on Nematostella cell type regulatory programs. Part of our @erc.europa.eu StG project, this was a challenging 5-year effort extraodinarily led by @aelek.bsky.social and @martaig.bsky.social. www.nature.com/articles/s41...

Thrilled to share that our new paper is out now in @natcomms.nature.com 🎉 Huge congrats to @vhrcabral.bsky.social and @karinaxavierlab.bsky.social on this major work. We found that our Klebsiella ARO112 can break the antibiotic/inflammation cycle in an IBD model

🧪 Dr. Emily Aguirre's final dissertation chapter is published! She isolated a putative bacterial symbiont then cocultured it with axenic algal symbionts to ask how it impacted growth and gene expression - results were unexpected but do support a beneficial relationship - read more here rdcu.be/eUKQz

A new combtooth blenny genome just dropped! Assembled from recycled ONT data + HiC + RNAseq. Thanks, Nikita Kulikov, Kim Joffroy, @ambonacolta.bsky.social @delcampolab.bsky.social for your hard work

So happy this is finally out! We reconstructed the 1st large-scale spatiotemporal dataset of 600+ MAGs from San Francisco Bay and show they have functional redundancy in key N and S pathways. These functions may better recover from disturbance in this highly urban estuary 💧

Interesting new research on the transcriptomics of Symbiodinid thermal tolerance from Xiang et al

New preprint! We explore how gutless marine worms and their bacterial symbionts use organosulfur compounds like DMSP and DMS - key molecules in marine sulfur cycling. Our results show that these compounds support carbon and energy metabolism in the Olavius algarvensis symbiosis.
