Imagine a ball thrown in the air: It curves up, then down, tracing an arc to a point on the ground some distance away. The path of the ball can be described with a simple mathematical equation, and if you know the equation, you can figure out where the ball is going to land. Biological systems tend to be harder to forecast, but MIT professor of biology Jonathan Weissman, postdoc Xiaojie Qiu, and collaborators at the University of Pittsburgh School of Medicine are working on making the path taken by…
