1: A Mystery Solved
In 1993, sixteen years after his death, former Vice President Hubert H. Humphrey, or more accurately, a tiny part of him, participated in a remarkable experiment. Scientists in Baltimore, using new laboratory tools, solved a long-standing but little-known mystery surrounding the late politician's death. In doing so, the laboratory detectives uncovered information about Humphrey that might have changed the course of American politics in 1968.
But this experiment meant more than rewriting history; it revealed that science was in the midst of cracking open one of nature's deepest secrets: what causes cancer.
