Susan Sontag in a bear costume

Each week, I'll pick a simple topic—think "fire," "dirt," or "orca whales"—and read a recent science paper related to that idea. I'll then share what I learned in a quick five-minute email. The goal of these weekly emails is to be an easy way to learn something new about different areas of research.
