The ultimate case of TMI: Behold my bellybutton's microbiome

By Carl Zimmer | January 25, 2011 9:00 am

Why is ScienceOnline a meeting like no other? Because it’s the sort of meeting where a biologist named Rob Dunn can set up shop in the lobby to ask for samples of bellybutton shmutz that he can analyze for biological diversity. Not only is it a place where such a person will not be hustled out by security, but it’s a place where a whole bunch of people respond by grabbing Q-tips to do their part for science. And you can bet every last bit of your bellybutton lint that I was right up near the front of the line.

Ten days later, my sample is now thriving nicely on a Petri dish, awaiting a more detailed analysis of its DNA. And here are the rest of the samples from the meeting.

All I can say is, #974, what is going on in there?

  1. What does it say about me that I am devastated that I couldn’t be there on the day they were testing bellybuttons?

  2. yikes…so why that? you know it is lint from your clothes and dead skin???? or do you?

    [CZ: I removed the lint before sampling--so these are regular resident of my skin.]

  3. I have a *sneaky* suspicion that #974 might be that guy who hasn’t bathed in EIGHT years! Did you talk to him?! Er, interesting.

    You and readers might be interested in the chat I had with 2 from Rob Dunn’s Belly Button Biodiversity team, Drs. Jiri Hulcr and Andrea Lucky, on our latest Science Cabaret on Air podcast: http://sciencecabaret.podomatic.com/

    Thanks for sharing your microbes! It’s fun to compare!

  4. I think the next Carnal Carnival has to be people all blogging about their belly button lint.

    We all contain multitudes.

  6. #974 has gone public, at least indirectly (compare with the samples at http://tinyurl.com/4ds4xvx). Maybe spending all that time up in the tropical canopy has something to do with it.

    But I’m jealous — my sample doesn’t seem to be ready yet.

    Its true, he did it. Actually, I helped Carl with this procedure — a bit of assistance in the men’s room, probably best spare you the linty details — and trust he’ll list me among the authors when the paper comes out.
