For anyone who hasn't trolled through my blogroll, I highly recommend checking out Carl Frederick's Website. It's not a blog, sadly, because I'd like to hear what the man has to say every day.
Especially recommended is his page connected to the musical fruit fly genome story. Carl is very interested in ideas connected to "first contact," and a lot of his stories are about that topic. But he always seems to do it in a way that no one else thinks of. Be sure to listen to the song.
