Recently I stopped by the offices of PBS Newshour to talk with correspondent Hari Sreenivasan about viruses–from the bird flu that’s in the news today to the viruses that swarm the oceans. Here’s the video, and here’s their story about our conversation.

This month has seen a flood of new studies and reviews on the microbiome, the collection of creatures that call our bodies home. In tomorrow’s New York Times, I look at why scientists are going to so much effort to map out these 100 trillion microbes.
The microbiome is not just an opportunistic film of bugs: it’s an organ that play an important part in our well-being. It starts to form as we’re born, develops as we nurse, and comes to maturity like other parts of the body. It stabilizes our immune system, keeps our skin intact, synthesizes vitamins, and serves many other functions. Yet the microbiome is an organ made up of thousands of species–an ecosystem, really. And so a number of scientists are calling for a more ecological view of our health, rather than simply trying to wage warfare against infections.

For a century, doctors have waged war against bacteria, using antibiotics as their weapons. But that relationship is changing as scientists become more familiar with the 100 trillion microbes that call us home — collectively known as the microbiome.
“I would like to lose the language of warfare,” said Julie Segre, a senior investigator at the National Human Genome Research Institute. “It does a disservice to all the bacteria that have co-evolved with us and are maintaining the health of our bodies.”
A new book is out, called Zoobiquity: What Animals Can Teach Us About Health and the Science of Healing, coauthored by cardiologist Barbara Natterson-Horowitz and science writer Kathryn Bowers. They take a look at the surprising parallels between animal and human health. The Daily Beast asked me to review it, and you can read my piece here.
The facts that animals and humans share an evolutionary heritage, and that we can gain medical insights through a comparison between species, are not new. And Zoobiquity contains some misconceptions about how evolution works and how to analyze it. Nevertheless, I think the book well-worth reading. I learned a lot from it about things ranging from cancerous rhino horns to anorexic pigs.
Check out my review here. (You can also read a fairly long excerpt from the book in the New York Times here.)
