We explore two astonishing tales where science and industry collided with world-altering consequences. First, the untold story of how Pemex geologists uncovered clues to the Chicxulub impact crater decades before its role in the extinction of the dinosaurs was recognized—a discovery delayed by corporate priorities and scientific blind spots. Then, we delve into the legacy of Thomas Midgley Jr., whose groundbreaking innovations in tetraethyl lead and CFCs solved pressing problems of his time but left catastrophic environmental and public health legacies. These stories reveal the uneasy, often dangerous, partnership between science and industry and the unintended consequences that have shaped our world.
