My new column about the brain has just gone up on the Discover web site. In it, I take a look at what happens when our brains get stretched, smushed, and otherwise injured. Brains don’t break like bones or rip like skin. Their injuries lurk down in the realm of molecules. And perhaps that’s where scientists will find a way to treat brain injuries. Check it out.

And I have to say that I’m not much closer to figuring out what parasitic wasps have to do with the show’s plot. I guess I’ll have to watch the whole episode. But–for the record–here it is:

I have a strange job. A few weeks back I was wandering through the aisles of the local Walmart, searching for bug spray, when my phone rang. A very excited Robert Krulwich was calling.
