Microbial ecosystems sustain all forms of life -including humans—in all environments. However, there are many unknowns about how these diverse and complex communities form, evolve and survive. The study of microbial ecosystems requires biology –and a lot of physics and chemistry, all combined. Dr. Otto Cordero’s (MIT) lab is a leading force in this field. He explains the physics and chemistry involved in the formation of these amazing -and essential- ecosystems. 00:30:08
