Studying hormones, Martin Rodbell and his colleagues discovered a mechanism that transformed our understanding of how cells respond to signals. In a series of pioneering experiments conducted at the NIH, Rodbell studied hormones--substances that have specific effects on cells' activity. He won the 1994 Nobel Prize for this work, explaining how our body makes sense of the world and winning a Nobel Prize.

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 The colorful glow of fluorescent chemicals can 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 Projectthe spectrophotofluorometer invented by Robert Bowman.

This looks at Discover the history of the home pregnancy test and examines test—developed at the NIH—and examine 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.
