With X-rays, doctors detect problems human eyes can't see. X-rays are a form of invisible radiation. This powerful medical technology helps experts look inside the body and even treat illnesses. But early on, X-rays caused harm too, as people used them without enough protection. This history covers the discovery of X-rays, the development of safety standards, and the rise of more powerful and precise X-ray machines. Find out how modern doctors create digital images of the inner body—even 3D images of our brains!

Chances are, you are familiar with the name Walter Reed only because you have heard of the major army medical center named after him. Maybe you have heard of his name in general references related to yellow fever. Either way, there is so much more to this humble, hard-working man than most know.

In order to bring its origin to light, Rebecca Skloot weaves together several narrative threads. One is primarily focused on Henrietta Lacks, the woman who, without her knowledge, became central to 20th century biomedical research. Another is the birth of modern biomedical research itself, and its roots in the American eugenics movement. Finally, there is the impact of this research, both of the Lacks Family and on society at large. Skloot divides the book into 3 parts: Life, Death, and Immortality.
