This summer, in cornfields in Iowa and Nebraska, about a thousand small point-and-shoot digital cameras will be enclosed in waterproof cases, mounted on poles and attached to solar-powered battery chargers. They will take pictures every ten minutes as plants grow; all part of a plan to create better seeds.

“We watch plants go through their normal growth and development and also we watch them respond to environmental stressors, like drought and so forth,” says Pat Schnable, director of the Plant Sciences Institute at Iowa State University.
