Students should feel free to go beyond the artificial boundaries which seem to be present due to their particular fields of study, and try to secure research opportunities in what they are keenly interested in doing or learning about. I think they should take advantage of opportunities to put their stamp on their research projects by digging into the existing knowledge base (papers, Internet, etc.) and bringing up novel ideas or generating hypotheses. A very useful book for serious undergraduate researchers, especially those who are interested in pursuing a career in lab research, is At the Bench by Kathy Barker.
