Dave DeAngelis interviews biologist Christopher Wills about his new book “The Darwinian Tourist: Viewing the World Through Evolutionary Eyes.” Wills discusses some of his adventures as a globe-trotting scientist, and describes how our understanding of the living world can be deepened by a Darwinian perspective. Rabia Yeaman talks with Robert Meeropol, son of Ethel and Julias Rosenberg about the constitutionality of dissent, The The US Espionage Act of 1917, and WikiLeaks.

If you use computers and internet, chances are you use open source software. Whether its word processing with OpenOffice, browsing the internet with Firefox, or serving up web pages with Apache, there's an open source solution for just about any problem. But can open source help us build a better voting system?

Dave DeAngelis speaks with Greg Miller of the Open Source Digital Voting Foundation about creating an open source, publicly owned, and trustworthy voting technology for any U.S. elections jurisdiction.

We'll also hear a recorded talk with Howard Rhinegold, Professor at Stanford and Berkeley, about how open source software encourages collaborative thinking and development.
