I’m delighted to be able to share the handsome cover of my next book. For the past couple years, I’ve joined forces with University of Montana biologist Douglas Emlen to write a textbook about evolution for biology majors. We built the book with some elements from my 2009 textbook for nonmajors, The Tangled Bank, along with much more math, additional concepts, detailed explorations of recent and classic studies on evolution, and study questions.

The book is slated to be published on August 15, 2012, in time for fall classes (here’s the book page on the publisher’s site). We’re still ripping through the final proofs, but as soon as the cover was officially approved, I had to share it. The insects are walking leaves, which are not only beautiful, but a marvelous example of evolution at work.

I think one of the biggest struggles a science writer faces is how to accurately describe the promise of new research. If we start promising that a preliminary experiment is going to lead to a cure for cancer, we are treating our readers cruelly–especially the readers who have cancer. On the other hand, scoffing at everything is not a sensible alternative, because sometimes preliminary experiments really do lead to great advances. In the 1950s, scientists discovered that bacteria can slice up virus DNA to avoid getting sick. That discovery led, some 30 years later, to biotechnology–to an industry that enabled, among other things, bacteria to produce human insulin.

This challenge was very much on my mind as I recently read two books, which I review in tomorrow’s Wall Street Journal. One is on gene therapy–a treatment that inspired wild expectations in the 1990s, then crashed, and now is coming back. The other is epigenetics, which seems to me to be in the early stages of the hype cycle. You can read the essay in full here.

In my new column for Discover, I write about Eric Courchesne, a neuroscientist at the University of California at San Diego. Courchesne survived childhood polio, went on to become a champion gymnast, and then turned his attention to another nervous system disorder: autism. Courchesne is one of the first researchers to find anatomical differences in the brains of people with and without autism. He believes his findings point to autism’s beginnings before birth, and perhaps even to new ways to treat it. Check it out.
