The Chemistry of Early Self-Replicating Systems

The NASA Specialized Center of Research and Training (NSCORT) in Exobiology is a consortium of scientists at the University of California at San Diego (UCSD), The Salk Institute for Biological Studies (Salk) and The Scripps Research Institute (TSRI). All three institutions are located in close geographical proximity in La Jolla, California. The NSCORT/Exobiology is administered through the Scripps Institution of Oceanography. Since its inception in January 1992, the NSCORT in Exobiology has made major contributions with respect to the question of how life began on Earth. The Principal Investigators (PIs) and their associated Fellows have published numerous articles in peer reviewed journals on topics relevant to Exobiology. They have presented papers and sponsored symposia at several meetings of national and international scientific societies. A total of 30 undergraduate, 12 graduate and 15 postdoctoral Fellows have been supported by the NSCORT. The Fellows have met on their own at least once a month to discuss Exobiology topics and research progress. The NSCORT has arranged seminars and evening discussion meetings, and offered an undergraduate class on "Biochemical Evolution" as well as graduate courses dealing with topics in Exobiology. A visiting scientist program has allowed 11 scientists from the U.S. and 4 foreign countries to conduct cooperative research with the various PIs. An active outreach program has been initiated, which includes an Exobiology high school level teaching module and curriculum guide, and an elementary school level booklet about basic atomic structure and formation of the universe, Sun and Earth. A World Wide Web Homepage (http://www-chem.ucsd.edu/-nscort/ NSCORT.html) has been developed, which describes the NSCORT activities, research programs and Fellowship opportunities. The various activities of the NSCORT in Exobiology have received wide-spread coverage in both the scientific and public media. The major function of the NSCORT is the training of young scientists in the field of Exo- biology. Thus, the bulk of the $1,000,000 annual budget is used to support the research and training of undergraduate, graduate and post-doctoral Fellows who are selected on a competitive basis. About five Fellows at each level are supported each year. Our goal is to train scientists whose major research interest is Exobiology, but whose mastery in the classical fields of chemistry, biology and earth science is so strong that they outstanding candidates for either graduate school or academic tenure-track positions in departments at leading national and international Universities. Applicants for these Fellowships are solicited by advertisements in journals such as Science and Nature and in organizational newsletters such as the one published by the International Society for the Study of the Origin of Life (ISSOL), by contacting academic and NASA colleagues working in Exobiology or related fields and by recruiting students who have already been admitted into the various academic programs with which the PIs are affiliated.
