A Kurdish activist in Stockholm runs a popular Facebook page devoted to saving the Syrian city of Kobane from Islamic State militants. But the page is under attack from Facebook administrators.

Also, the Volkswagen scandal as seen from an American dealer's point of view.

And we meet Christian Ray Flores, the man who supplied the soundtrack for Boris Yeltsin's Rock the Vote.
