"That got us all thinking," said O'Halloran. "Could zinc be a signal in the fertilization process? The evidence was strong enough for us to pursue. We first want to test whether there is a zinc signal pathway and then build a model of how zinc acts in the egg. This is very exciting because zinc's primary role in the body is typically thought to involve catalysis, not signaling."
