The Royal Society and Royal Academy of Engineering released on July 29, 2004, their report entitled Nanoscience and Nanotechnologies:  Opportunities and Uncertainties. To mark the five-year anniversary of the report, The Responsible Nano Forum invited representatives from science, risk, investment, non-governmental organizations (NGO), unions, business, and consumer groups to reflect on the legacy of the report and what still remains to be done. The report, A Beacon or Just a Landmark?  Reflections on the 2004 Royal Society/Royal Academy of Engineering Report, includes contributions from a range of individuals and organizations in the United Kingdom and internationally. We are pleased to announce that Lynn L. Bergeson is a contributor.
