The Center for Responsible Nanotechnology has announced the first series of its research papers, in which experts in the field examine the potential outcomes of this technology; all but one of the essays are available for publishing or reprint under Gnu Free Documentation License (GFDL). SF fans may be interested to note that David Brin is one of the contributors. Another is the redoubtable Ray Kurzweil, who is hosting discussions of the papers on his futurist site KurzweilAI.net.
