It’s been nearly ten years since President Bill Clinton stood on the White House lawn with a team of scientists to announce the completion of the first survey of the human genome. “Today, we celebrate the revelation of the first draft of the human book of life,” he said. It’s a pleasing metaphor, but it’s deeply flawed. There is not a single Human Book of Life. If there were, after all, Clinton and the scientists and all the rest of us would all be identical clones.

I was stunned to learn that National Geographic has never published a story on carnivorous plants. So I wrote one. It’s now out in March issue, as well as on the NG web site. It should come as no surprise that the article is accompanied by dazzling photos that will probably make most readers forget that there’s a story lurking in the shadows, too. You can look at the pictures in the NG slideshow, and see some extra outtakes on the web site of the photographer, Helene Schmitz.

Last March a new kind of flu came on the scene–the 2009 H1N1 flu, a k a swine flu. Hatched from an eldritch mingling of viruses infecting humans, birds, and pigs, it swept across the world. Here in the United States, the CDC estimates that between 41 and 84 million people came down with swine flu between April and January. Of those infected, between 8,330 and 17,160 are estimated to have died. For more details on the evolution of this new flu strain, here’s a video ofa lecture I gave in November.
The warming climate may earn carbon dioxide all the headlines (including ones about senators who can’t tell the difference between a couple blizzards and a 130-year climate record), but the gas is having another effect that’s less familiar but no less devastating. Some of the carbon dioxide we pump into the air gets sucked into the ocean, where it lowers the pH of seawater. We’ve already dropped the pH of the ocean measurably, and as we burn more fossil fuels we will drop it more. Ocean acidification has the potential to wreak world-wide havoc on marine life.
Today in Yale Environment 360, I write about scientists comparing today’s ocean acidification to the last time something comparable happened–55 million years ago. Short answer: today’s is big. Really, really big. Check it out.

Charlie writes, “I am a scientist at the University of Minnesota. In 1999, as an undergrad on a plant science internship, a friend and I were sitting on our dorm roof, wondering what the best nerdy science tattoo would be. The double helix down the leg or back was suggested, but we concluded that a chloroplast was a better fit for our scientific interests. As the photon-collecting organelle in plants, it’s the source of energy for nearly all plant life and a fascinating biochemical machine. At that point in our careers, we found something that would represent our fascination with plants, no matter what field we chose to pursue. He is in botanical education (and didn’t go through with the tattoo), I’m in horticulture.”
