Iowa State engineers turn LEGO bricks into a scientific tool to study plant growth

Ludovico Cademartiri had what seemed like an impossibly demanding list of requirements for his lab equipment.

The Iowa State University assistant professor of materials science and engineering wants to understand environmental effects on plant growth, specifically how variations in climate and soil characteristics affect root growth. That requires highly controlled environments that expose whole plants to environmental effects such as nutrients, water, oxygen gradients as well as physical obstacles for the roots.
