while i AM looking forward to (someday) trivially assembling single contig MAGs from long-read data... picking out coherent contig clusters in #anvio will always be very satisfying!

an important piece of work, beyond just the marine realm - showing that long read tech not only can mean better genomes but more diverse and possibly previously unresolvable ones!
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. 🙂

Is your NSF grant on this list? Reach out if so!

Ted Cruz released a list of grants flagged for DEI or "neo-Marxist class warfare propaganda" from his Oct. report.

NSF is using keywords from that report for their review, though Cruz's list is likely larger.

Fellow UC professors, what can we do to advocate for the NSF postdoc fellows (and potentially additional fellows next) who cannot withdraw their paychecks?

Our most recent paper on methane seeps is out: bg.copernicus.org/articles/22/.... Two seeps in Monterey Canyon have virtually no ANME (methane oxidizers), suggesting an unabated methane flux at these and similar seeps. The microbiological methane filter in sediments is not ubiquitous.

Abstract. Marine hydrocarbon seeps typically harbor a relatively predictable microbiome, including anaerobic methanotrophic (ANME) archaea. Here, we sampled two cold seeps in Monterey Bay, CA – Clam F...

Wetting dry soil rapidly stimulates microbial activity and has important consequences for biogeochemical cycling. In our paper out today, we show that part of that response can be explained by how bacterial genomes are written (i.e. codon usage, nucleotide freq., genome size)
