I imagine there are some academic types among us that would go for this sort of thing.
Gut Check: Exploring your Microbiome is a free online course offered by University of Colorado via Coursera
Dates: Oct 6 -> Nov 14, 20014
The human body harbors up to ten times as many microbial cells as human cells. What are these microbes and what are they doing? How can we study them to find out? What do they tell us about
ourselves? Just as our human genome records traces of who we are and the conditions we have adapted to during evolutionary history, our microbial genomes may record traces of what we have eaten, where we have lived, and who we have been in contact with. The microbial ecosystems in different parts of our bodies, which differ radically from one another, also supply a wide range of functions that affect many aspects of human health.
