Nanotechnology breakthroughs could pose threat to Midwest crops

Fast-developing know-how makes our khakis resist stains, artificial bones more practical and diesel burn more efficiently. That nanotechnology builds microscopic wonders inhabiting a man-made universe that smothers stink and mops up pollution by working on a scale that makes a dust mite look gargantuan. Yet research still in its infancy, and trailing the deployment of emerging commercial applications, suggests those same breakthroughs in nanotechnology might some day make Midwestern crops less bountiful.
