This week we discuss the grassroots effort to add bike lanes to LEGO modules, and we mark the passing of a giant in the field of sociology. And, I recently spoke with Professor Michael Light of the University of Wisconsin-Madison about his recent paper titled "Undocumented immigration and terrorism: Is there a connection?" The paper is to be published in Social Science Research, and is co-authored by Julia Thomas.

Segment 1 -- Michael Light on "Undocumented immigration and terrorism: Is there a connection?"
