Welcome to the inaugural installation of Sunday Science! For those who don't already know, my lab here at HSPH has been slowly ramping up since I started last summer. Now that there's a really great group of people helping me out here, I'd like to take the time to work on some fun projects in between grantwriting. That includes posting articles here in an effort to capture in organized form questions, thoughts, or (remarkably) actual science that's come up over the past week. I'll be keeping myself honest by posting each Sunday - hence, Sunday Science. Because we never get a day of rest in academia anyhow, right?
