You really are missing the point of the headline, which purpose is to attract readers to a subject they wouldn't otherwise be interested in.. and the fact that "even a kid from a trailerpark can up-end cemented thinking in science" is very relevant. It does, in fact, change everything: the scientists' class and social background is not relevant to the science he or she performs, but the fact of extraordinary science being performed by extraordinary individuals is relevant. Maybe there was something in his trailerpark lifestyle that made him start to think differently about the things he'd learned about as a scientist; you, the reader, are invited to make your own conclusions before you walk away. The title is a part of that process.
