Class Prep for Mar. 23: get to know your microbes

Now that you’ve looked at the fundamentals of cell biology, it’s time to go beyond the textbook and consider the bacteria that live in and on us. For class on Wednesday March 23th, watch this TED talk by Rob Knight and work through the items below.

  • Jot down three specific takeaways in your notebook.
  • Consider the image of “microbes” found in the gut shown at 1:15. What kind of microscope was used to produce this image? Why does it have color?
  • How are microbes in the human microbiome identified and characterized?
  • According to Rob Knight, how many “human” cells make up a typical person’s body? How many “other” cells are there?
  • What happens to many children who are given antibiotics within 6 months of birth?
  • What connection (even if only speculative) can you draw between this talk relate to the probiotic items in the recent class discussion post?
