A note for my regular readers: I am taking the next two weeks off to spend time with my family. I won’t be totally out of touch—I will still write the Monday Update—but I am turning the blog over to some of my colleagues so you can see what great work they do. For the next two weeks, you’ll find new posts here on Monday, Wednesday, and Friday; we will return to the usual daily schedule on Monday, August 29. Until then, take care! — Brad
