For Nov. 1: How our microbes make us who we are, TED talk by Rob Knight

For class on Tuesday, Nov. 1st, please come in having watched this TED talk by Rob Knight and worked through the items below.

  • Jot down three specific takeaways.
  • 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 a number of children who are given antibiotics within 6 months of birth?
  • What connection (even if only speculative) can you draw between this talk and probiotic products you may have seen or heard about in recent years?
