Wondering why your biology textbooks never explained the “Amazon rainforest” of microbes living in and on your body? In fact, a colossal global-level project to unravel the full complexity of the microbes that accompany us in our daily lives – the Human Microbiome Project – was only recently completed. Abandoning older culture-based techniques in favor of more accurate genetic sequencing, the project was able to identify more than 500 different species co-habiting on skin alone. With myriad health benefits, the microbiome is like a brand new second skin that has just been discovered!
