Diabetic patients may someday reduce their insulin injections and lead more normal lives because of new insights gained through irnovative space research in which insulin crystals were grown on the Space Shuttle. Results from a 1994 insulin crystal growth experiment in space are leading to a new understanding of protein insulin. Lack of insulin is the cause of diabetes, a desease that accounts for one-seventh of the nation's health care costs. Dr. Marianna Long, associate director of the Center of Macromolecular Crystallography at the University of Alabama at Birmingham, is a co-investigator on the research.
