Today’s Digest includes plenty of human gut microbiome papers, and plant, soil, water microbiome papers. Today features a major expansion of human gut MAGs, evolution of human gut microbiome compared with apes, and how soil microbiome affects climate change and vice versa. A potentially revolutionary technology promises to finally bring microbiome dark matters into daylight, and don’t forget to check out our own Elies Bik’s excellent work on exposing scientific fraud! Enjoy.
