The Political Junkie
After months of partisan fighting, Congress finally passed a plan to reduce the debt and increase the federal borrowing limit. The president signed the bill into law yesterday without a signing ceremony, likely because the public called the debate "ridiculous," "disgusting" and "stupid." Those findings come from a Pew Research poll of the debt debate. It finds that more than 70% of Republicans, Democrats and independents had negative assessments of the negotiations. Andrew Kohut, president of the Pew Research Center, talks about the winners and losers in the debt debate with political junkie Ken Rudin and guest host Tony Cox. The two will also recap the week in politics, from a new Congressional map in California to a Rep. Gabrielle Giffords's surprise return to Congress.

MTV Turns 30
At midnight on August 1, 1981, MTV co-creator John Lack uttered the words "Ladies and gentlemen, rock and roll," and the network premiered its first music video, Video Killed the Radio Star, to an audience of a few thousand. Reality shows like "The Real World" or "Jersey Shore" had no part in the programming 30 years ago. The 24-hour network was all about music videos, VJs and music news, and it changed the way fans related to their music. Guest host Tony Cox looks at the evolution of the network and takes listeners calls about memorable MTV moments.

Counting Calories
When it comes to watching your weight, many Americans are obsessed with one thing: calories. We count them, we track them — and feel guilty when we ignore them. The nation's new health care law will soon require chain restaurants to display calorie information on their menus, as many cities already do. But many of those counts are off by hundreds of calories. And even accurate counts often don't change the way we eat. NPR's Tony Cox talks with health researchers about how we count calories, whether menus are accurate and why counting calories isn't enough to ensure a healthy diet.

Rising Temperatures And Crime Rates
When temperatures rise, the conventional wisdom goes, so do crime rates. As many cities continue to face triple-digit heat, Wired magazine examined what science has to say about any connection between heat and crime. Their finding: "The answer... is hazy and hotly contested." One theory suggests that high temperatures do appear to affect judgment, but another suggests that extremely high temperatures drive people indoors, and crime drops. Guest host Tony Cox tries to make sense of the research with Wired's Brandon Keim.
