The field of synthetic biology (the name is derived from an analogy to synthetic chemistry) has recognized itself as a "field" only since about 2002. Synthetic biology has gotten some high-profile attention recently, but most people are not aware the field even exists. Synthetic biologists apply engineering principles to genomic circuits to construct small biological devices. The Jamboree, as it was affectionately called, was the culmination of a summer of undergraduate research on five campuses across the United States. The participants shared data, frustrations, lessons learned, and plans for the future. The entire weekend was, to some extent, a pyramid turned upside down. Normally, new fields in biology are explored first by postdocs and graduate students under the watchful eyes of their Primary Investigator (PI) mentors. This National Science Foundation (NSF)-supported Jamboree featured undergraduates (some having just completed one year of college) who were pushing the boundaries of a field so new, its name is subject to debate. This report highlights some of the interesting research conducted by undergraduates during the summer and early fall of 2004. (Contains 5 figures and 1 footnote.)
