The next time you’re looking for something fun to do and you inevitably turn to picking up a scientific article, you may find some familiar lyrics. According to The Local, five Swedish scientists got so bored writing about science that they placed a bet with each other to see who could squeeze in the most references to Bob Dylan lyrics in their papers before they retire. The game began 17 years ago with two professors who wrote a paper about intestinal gas (isn’t science fun?) and called it “Nitric Oxide and inflammation: The answer is blowing in the wind,” which is of course a reference to Dylan’s “Blowin’ In The Wind.” They went on to recruit a few more scientists in their little game, and the winner of the bet will apparently get a free lunch at a local restaurant. Other paper titles include: “The biological role of Nitrate and Nitrite: The times they are a-changin,” “Blood on the tracks: A simple twist of fate,” “Eph receptors tangled up in two,” and “Tangled up in blue: Molecular cardiology in the postmolecular era.”
