By the 1950s, synthetic fabrics - often wrinkle resistant and flame retardant - began to overtake cotton as the dominant U.S. textile fiber. To reverse this trend chemists and chemical engineers at the Southern Regional Research Center initiated research to modify cotton chemically. Their efforts in developing agents that crosslinked the cellulose fibers and in establishing crosslinking mechanisms led to improved durable press fabrics. SRRC studies also developed new agents that improved the durability of flame retardant cotton to laundering.

In the early 1970s, American chemist Paul C. Lauterbur demonstrated that nuclear magnetic resonance (NMR) could be used to generate images of macroscopic objects. In the years following, magnetic resonance imaging (MRI) has been refined as a technique for the detailed resolution of internal structures. Lauterbur’s invention thus created a powerful diagnostic tool for the non-invasive examination of body tissues such as the brain, heart, and muscles. It allows for the early detection of cancer and other diseases.
