<p>CHICAGO, Illinois (AP) -- Sho Yano's mother hands him his lunch for school in a brown paper bag -- a turkey sandwich and cookies included.</p>
<p>"You don't need any bones today? No bones?" Kyung Yano asks her quiet, spectacle-wearing 12-year-old, who shakes his head "no" as they head out their apartment door. She wants to make sure he isn't supposed to take his samples of spinal bones and a human skull to class, where he's learning about human anatomy.</p>
