Nanotechnology has been around for more than 30 years, if you can believe it, and just the word -- nanotech! -- still seems to create wild excitement about the possibilities of being able to work at such tiny scales. More and more, though, the excitement is tempered with concern about the social and ethical issues associated with the development of nanotechnology. Who will get access to the new innovations that nanotech will usher in? Who is overseeing the research to make sure that new products are used for the good of society? Mike Skvarla, user program manager at the Cornell Nanoscale Facility (CNF), joins host Jenny Nelson to discuss these concerns as well as a new program started by CNF and the National Nanotechnology Infrastructure Network called the 'Social and Ethical Implications of Nanotechnology' program.
