This looks at the history of the home pregnancy test and examines its place in our culture. Research that led to a sensitive, accurate pregnancy test was done by scientists in the Reproductive Research Branch of the National Institute of Child Health and Human Development at the National Institutes of Health.
In the 1950s, the NIH's Dr. Robert Bowman developed a sensitive instrument called the spectrophotofluorometer, or “SPF”, that allowed scientists to use fluorescence as a way to identify and measure tiny amounts of substances in the body. This exhibit explores the instrument and its use in scientific studies ranging from anti-depressant medication to AIDS research and the Human Genome Project.

Innovation and Invention: NIH and Prosthetic Heart Valves
The development of artificial heart valves involved surgeons, engineers, patients, and regulators. This exhibit explores their stories and presents current and future examples of artificial heart valve innovation. The exhibit is currently in the process of moving from the NIH to the FDA and is expected to be on display again by 2020. The virtual exhibit is under construction and the physical exhibit is currently on display at the FDA.
This type of balance is designed on a “seesaw” principle to measure mass precisely by placing a sample in one pan and a known weight in an opposing pan until an equilibrium was established.
