  1. Re: the letters to ear candlers…nice! I had a guy from Wally’s Natural Products commenting on my ear candling blog post…those ear candling fans make weird claims. I especially love the last paragraph in the letter. I’ll be checking their website to make sure they follow through!

  2. Am I the only one that read that as “Human gut microbes hold ‘second gnome'”?

    My mind went crazy for about 3 seconds with the awesomeness of having microbial gnomes in my stomach… then I saw the ‘e’. And while a second genome is pretty bad ass, 2 gnomes living in my belly is way cooler!

  3. @Nicole: The geometry of this boggles my mind. Are they just a lot smaller than human cells by volume?

    As @catgirl said, yup. Another fun fact: there are more bacteria cells on your skin than skin cells in your skin. Just shaking hands with someone sets up a cross-cultural bacteria orgy on an epic scale.

  4. @Nicole: An e. coli bacterium is about 3 micrometers long and a skin cell is about 30 micrometers in diameter. The mitochondria in cells are not-so-coincidentally about the same size as bacteria. (mitochondria, chloroplasts and bacteria probably share a common ancestor)
