Roco's optimistic look at nanotechnology in "Nanotechnology's Future" [Forum], some issued thoughtful caveats about its unforeseen dangers.

The bulk of the dissent, however, was reserved for the cover story "The Expert Mind," by Philip E. Ross, which suggested that studies of the development of chess grandmasters' mental processes may reveal how expertise in all fields is fostered.
