Universities today face incredible challenges, and in our latest Omnia, we aim to address those head on, like with our cover story on democracy and our feature about why fundamental research matters. Beyond that, we use a graphic-novel approach for the first time in our pages, highlighting the science behind the mud on Major League baseballs. Plus, we offer up a conversation about choice and another about anime and religion; a fruit fly mating chamber; the introduction of Mark Trodden as the new Dean of Penn Arts & Sciences; the story of a long-long Chopin waltz; Titanic archival materials; and so much more.
