Yesterday, I wrote about how snakes use their scales to help them crawl without legs. But what if you don’t have bones–what if you’re just a single cell? I’ve always been fascinated by how cells crawl about, like minuscule versions of The Blob. I recently had an excellent time talking to some of the scientists who are figure out what goes on inside cells when they go from point A to point B. And that’s the subject of my article in today’s New York Times. Be sure to check out the video and graphics that go along with it. It’s alive!
