In my new podcast I take a look at Darwinian agriculture–how farmers can improve their crops by taking advantage of evolutionary history. I talk to Ford Denison of the University of Minnesota, who has done fascinating work plants such as soybeans and the bacteria that live in their roots and supply them with essential nitrogen. It’s a complicated relationship, full of cooperation, conflict, cheating, and punishment. Check it out.

When I’ve traveled abroad, I’ve gotten my share of jabs for hepatitis and other diseases. But for malaria, the best I could hope for was to take malaria-blocking drugs like Lariam, which gave me weird dreams at night and made me feel as if someone was tugging my hair all day.

For people who live in countries with malaria, these prophylactic drugs just aren’t practical. Given that 800,000 people a year die of malaria, why don’t we have a good vaccine for it? It’s not for lack of trying–in fact, this year marks the 100th anniversary of the first attempts to make a malaria vaccine.

To understand this epic fail, I talked on my latest podcast with Irwin Sherman, a malaria expert and author of The Elusive Malaria Vaccine: Miracle or Mirage?.

In my lastest podcast, I talk to Keith Klugman of Emory University about pneumonia–how its devastation worldwide is worse than we once thought, and how vaccines are proving surprisingly effective at keeping it in check. A pneumonia vaccine may even prevent a replay of the 50 million deaths during the 1918 Spanish flu pandemic. Check it out.

Did pregnancy tests help drive frogs extinct around the world? In my latest podcast, I talk to wildlife disease expert Peter Daszak about his research on how germs can drive animal species to extinctions, and jump from animals to us. Check it out.

Ed Yong, thankfully, is all over a new study on how the microbes in the guts Japanese people acquired genes from ocean germs to digest sushi. It’s yet another example of the mind-blowing science emerging from the study of our microbiome–the trillions of non-human organisms that share our body with us. For more on the microbiome, listen to my recent podcast with microbiomist (I just made that up, but it feels so right) Rob Knight.

I’d have blogged on this too, but I’m busy with something in the works for tomorrow. Stay tuned.

Line up all the viruses on Earth end to end (go ahead, I’ll wait), and they’ll stretch over 10 million light years. In my new podcast, I talk to Curtis Suttle of the University of British Columbia about what it means to live on a virus-dominated planet.

E. coli that can count? In my new podcast, I talk to James Collins, an engineer-turned-biologist who helped usher in the science of synthetic biology ten years ago. We talk about the challenges of getting cells to do what you want them to, and what synthetic biology will look like in 2020. Check it out.

In my newest podcast, I talk to a kind of viral Indiana Jones. Michael Worobey of the University of Arizona chases down the evolutionary origins of viruses such as HIV and the flu no matter what it takes–including getting dangerously ill in the middle of a civil war. Check it out.

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.

Are antibiotics weapons of war, or a microbial language for cooperation? In my latest podcast, I talk to Julian Davies about the history and future of antibiotics, the marvelous yet mysterious creation of microbes that changed the course of medicine. Check it out.

In my latest podcast, I speak to Penny Chisholm, an MIT microbiologist who studies the marine microbes that make a lot of the oxygen on which we survive, and who sees the ocean as a giant sea of virus-shuffled genes for harvesting sunlight. Check it out.

How does a scientist study a million genes? In my latest podcast I talk to John Wooley, a leading figure in the new science of metagenomics. Check it out.
