Summary: This week in Studio 360, two takes on motherhood. In Isabella Rossellini’s new series of web videos, she acts out unusual childrearing strategies — abandonment, cannibalism — in the animal kingdom. And a listener explains how Mary Karr taught her what she needed to know about having a teenage boy. Plus, a physicist finds beauty in the race to find dark matter, and musician Marques Toliver finds the common ground between Quincy Jones and J.S. Bach.
