New research from our lab revealing pervasive genomic islands (GIs) in giant viruses (GV). Leveraging long-read assembled GV genomes we reveal these GIs, their functional repertiore and roles in GV genome variation. Research led by PhD candidate Benjamin Minch! www.nature.com/articles/s41...

Preprint alert! Giant viruses from deep-sea hydrothermal vents aren’t isolated; they’re globally distributed. Hydrothermal plumes may carry them into the global pelagic ocean, linking distant ecosystems. www.biorxiv.org/content/10.6...

This is from 7 years ago (merenlab.org/2019/02/24/f...). We are talking about the same things today. We will be talking about the same things 7 years from now. There is no one to blame for this apart from ourselves. I find it very depressing.
