Jonah Marks, a University of Iowa PhD candidate in chemical and biochemical engineering, created a better way for scientists to find "transition states" in chemical reactions that are essential to design new medicines, better catalysts, and advanced materials.

UI engineering professor and hydroscience director Larry Weber said it’s clear that nitrate concentrations have increased in Iowa over the past decades. “Not only should we have the sensors we have, we should have more out there to provide a more uniform network across the entire state,” Weber said.
