TEDYouth is in its second year of putting together an afternoon of short talks for high school students. I’ll be joining in with a quick introduction to my favorite parasite. The event, which takes place in New York City, will be live-streamed–visit this page for more information for viewing. It will run from 1 pm to 6 pm ET. I’m scheduled to talk at 2:45.

In May I wrote in Discover about a major experiment in neuroscience. Ahmad Hariri, a neuroscientist at Duke, is gathering lots of data from hundreds of college students–everything from genetic markers to psychological profiles to fMRI scans. He hopes that the Duke Neurogenetics Study, as he’s dubbed it, will reveal some of the ways in which the variations in our genes influence our brain circuitry and, ultimately, our personality and behavior.

Hariri plans to collect data from over 1000 people, but he and his colleagues are already starting to analyze the hundreds of students they’ve already examined to look for emerging patterns. In the open-access journal Biology of Mood and Anxiety Disorders, they’ve just published some of their first results. While the results are, of course, preliminary, they do offer an interesting look at the future of neuroscience. Rather than pointing to some particular gene or brain region to explain some feature of human behavior, neuroscientists are learning how to find patterns that emerge from several factors working together.

Over the past few weeks, I’ve been dipping into a project called “Moby Dick Big Read.” Plymouth University in England is posting a reading of Moby Dick, one chapter a day. The readers are a mix of writers, artists, and actors, including Tilda Swinton. They are also posting the chapters on SoundCloud, which makes them very easy to embed. Here is one of my personal favorites, Chapter 32, “Cetology.”

When I was an English major in college, I read Moby Dick under the guidance of English professors and literary critics. They only paid attention to a fraction of the book–the fraction that followed Ishmael on his adventures with Captain Ahab. This was the part of the book that they could easily compare to other great novels, the part they could use for their vague critiques of imperialism, the part–in other words–that you could read without having to bother much with learning about the particulars of the world beyond people: about ships, about oceans, and, most of all, about whales. How many teachers, assigning Moby Dick to their students, have told them on the sly that they could skip over great slabs of the book? How many students have missed the fine passages of “Cetology”?
