An implantable insulin pump for diabetics is a step nearer thanks to a mathematical model that draws inferences from changing blood glucose levels. The algorithm can be encoded in a computer program that fits inside a 30-kilobyte memory chip, say its developers at the University of Delaware in Newark. Today’s external pumps deliver a continuous trickle of insulin, but Frank Doyle and Robert Parker’s program predicts the patient’s need for insulin every five minutes. “If the glucose is going up quickly, the algorithm infers that a meal has been ingested and the pump can respond quickly,
