And now it's time for "BackTalk." That's where we hear from you. Editor Ammad Omar is back with us. What do you have for us this week, Ammad?

Photographer Kirk Crippens says you can't. But that hasn't stopped him from trying. Since 2009, he has been documenting the city of Stockton, Calif., which last year became the largest city in American history to file for bankruptcy — until Detroit filed yesterday.

The Sweat Machine extracts moisture from worn clothes by spinning and heating them, then filters the resulting liquid so that only pure water remains. It was built by Swedish engineer and TV personality Andreas Hammar, and uses a technology developed by Sweden's Royal Institute of Technology and the water purification company HVR.

"Ramadan is a big change in routine," says Jehad Outteneh, a Palestinian in Jerusalem who shops and cooks for her family of eight.
