Caption: On Nov. 7, 2007, Kathy Nelson, a researcher at the Wisconsin Center for Dairy Research at the University of Wisconsin-Madison, mixes up a batch of protein-fortified pudding designed for people with phenylketonuria. Nelson is assessing whether a unique protein found only in whey, the liquid byproduct of cheese, can potentially help people who suffer from this rare genetic condition.
