It's Labor Day. So ahead of the Labor Department's jobs report released this Friday, we take a look at the job opportunities that are out there. As the end of summer draws near, we explore how a song becomes a summer hit. And are you planning to cook today? We look at the (dying?) business of cookbooks. Plus, Secretary of State Hillary Clinton pushes China on territorial disputes, France mulls the costs of preserving its old churches, two expatriates in the U.K. discuss life from across the pond, and there's a new way of building affordable housing in Mexico.
