🚨New pub is live! It was really fun to write this with my friend @carolinamicro.bsky.social. If you're curious about how phylogenomics has shaped our understanding of early life and want guidance on how to do this kind of work yourself, then this review is for you. Enjoy! 🚀

We’re trying to put some together as well!

Looking for suggestions for concentrating multiple low concentration, replicate 50 uL DNA and RNA extractions ranging from 0-3 ng/uL. Column or mag bead preference? Or SpeedVac? TIA!! Please share.

Ecological constraints and evolutionary trade-offs shape nitrogen fixation across habitats Abstract. From its earliest beginnings, life’s expansion into new habitats has been profoundly shaped by its reciprocal interactions with a changing Earth.

Latest work! 🧬

We uncover how evolution of translation initiation factor 2 (IF2) extensions links translation to bacterial stress response. We map 7 structural architectures & show how terminal extensions are enriched in intrinsic disorder & phase-separation features.

What happened before the last universal common ancestor? Pre-LUCA evolution is hard to study. In our new Cell Genomics Perspective we spotlight how paralogous proteins open a window onto the deepest chapters of evolution. 🧬🌍

New paper! Why are some Nitrogen fixing microbes more complex?

@msobol.bsky.social et al. find that microbes with more N2-fixation genes have larger, more versatile genomes, showing how changing environments shaped this key metabolism!

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 💧

Would love to know more about that water filtering set up! 👀

This is so cool!

Safe travels!
