Thanks to the work of the decade-long, $3 billion Human Genome Project, human society has gained much greater insight into our bodies and our health. Scientists have identified genes that contribute to disease, stoking hope for ways to treat or eradicate cancer among many other ailments. This new Smithsonian exhibition, which will travel the country later next year, explores the work and growth in sequencing technology that helped spark this medical and scientific revolution.
