One of the most mind-blowing things I learned about while writing my book Microcosm: E. coli and the New Science of Life was the incredibly diversity of microbes that call our bodies home. These microbes outnumber our cells by about ten to one, and collectively they have thousands times more genes than found in the human genome. E. coli may be the most familiar of these lodgers, but it is just small player in an inconceivably complex ecosystem on which our health depends.

So I was very excited to interview Rob Knight of the University of Colorado, a biologist who’s been co-authoring a string of stunning papers recently on the thousands of species that live on our skin, in our mouths, in our guts, and elsewhere on or in our bodies. Our conversation is now available on the latest “Meet the Scientist” podcast. We talk about how microbes help each other thrive in our bodies, the way bacteria in our guts release neurotransmitters, how microbes may regulate your weight, and much more. Check it out.

Thanks to the UK Times for including The Loom among their top science blogs. It’s great company to be in, including fellow Discover blogs Bad Astronomy and the Intersection. I am just going to assume that the Times has not yet discovered Cosmic Variance, because its omission is a gross oversight.

I also think their description of the Loom as “authoritative science writing” may be a bit of an oversight, too (as flattering as it maybe). I mean, really: Duck porn? Tattoo parlors? Cockroach zombies? Other adjectives come to mind…

I first met the writer Rebecca Skloot about eight years ago. She had been working on a book for a couple years and running late. The idea was brilliant, though, so I hoped she’d be able to get it done before too long. Many scientists who study human cell biology use a special line of cells known as HeLa. It came from a woman named Henrietta Lacks, who died of cervical cancer in 1951. Skloot was writing about Lacks, her family, and the way her body became dispersed around the world.

When I would see Skloot again, I’d ask how the book was going. Still going. After a while, I stopped asking, because I know how irritating that question can get when the answer hasn’t budged for a while. When the book was done, it would be done.

I got an email today from a college student interested in becoming a science writer, asking how I got into the field and how it works. I get these emails from time to time, and in the past I’ve replied with an email of my own. But it occurred to me today that it would be better to direct them a podcast.

In November, when I visited the University of British Columbia, I gave a talk at their journalism school about how I became a science writer, and what it’s like for me today. It may not be interesting to people who are interested in science, rather than the business of science writing. But if you’re curious about this peculiar way of life, check it out.

This link takes you to the University of British Columbia on Itunes. Scroll down to find the podcast with my name on it.

Next month I will be part of a virtual book party. Here’s the deal: the American Institute of Biological Sciences is inviting fellow Disco-blogger Chris Mooney and me to talk about our recent books via video. Registered participants can then ask questions and discuss the books. Plus, a couple lucky registrants will win a copy of our books! You can find more details and register here. (Space is limited.)
