Fantastic work led by @stevenjrobbins.bsky.social @ace-uq.bsky.social describing the most comprehensive (to date) microbial genomic resources from the Great Barrier Reef FINALLY, powered by @nanoporetech.com!
Very excited to present the Great Barrier Reef Microbial Genomes Database (GBR-MGD), a comprehensive DB of 1000s of high-quality prokaryote, virus, plasmid, and chromosome-level eukaryote MAGs using Nanopore long reads. Subthreads incoming. Please share widely. 🙂

But in reality, the account appears to be run by a disgruntled scientist with dozens of problematic papers.

We used Great Oxidation Event as a planet-sized "fossil" to add ancient dates to the Bacterial tree of life. @theconversation.com and @science.org articles show oxygen was used by non-cyanos before that cataclysm, surprisingly. theconversation.com/1-trillion-s... www.science.org/doi/10.1126/...
1 trillion species, 3 billion years: how we used AI to trace the evolution of bacteria on Earth
Until now, it’s been very hard for scientists to establish a detailed timeline of the early evolution of bacteria.
