More and more on the microbiome. In “Taming Your Guts” I call this the “ecology” in the colon but now the US Government is sponsoring the microbiome with big funding so it’s time for me to get on board with the new name. Symposia devoted to this topic are springing up with speakers going deep into speculation: the microbiome as a factor in aging, autoimmune diseases, psychiatric disturbances, etc. Enough on this for now, but best to keep watching.
