This weekend, a court in Moscow sentenced three women from a previously obscure punk band guilty of hooliganism. They got two years in prison and made Pussy Riot an international sensation. In the Washington Post today, columnist Anne Applebaum writes that for all the attention paid to the case, Madonna's was by far the most damaging, not because she's a serious political figure, but because she isn't.

There's growing evidence that the bacteria in our gut influence our health, including how much we weigh. So what happens when antibiotics knock out some of the microbes that help us?

A study, published online today in the journal Nature, finds that antibiotics make young mice fatter by changing the mix of their gut bacteria.

In Colorado and Iowa, two states considered up for grabs in the presidential race, a battle over alternative energy policy is playing a growing role in the debate between President Obama and Mitt Romney.

Both states have important wind-energy sectors, and Obama's campaign is rolling out new radio ads this week highlighting the president's support for — and Romney's opposition to — extending a tax credit on wind-energy production.

AT&T is on the defensive today, saying that its decision to limit the use of Apple's video-call app Facetime does not violate the FCC's net neutrality rules.

Ever since Apple introduced the application, AT&T has limited its use to Wi-fi. In other words, customers who were using the AT&T network could not make video calls using the built-in app. Last week, AT&T changed that policy, saying it would allow customers on its new "shared data plans" to use the app but that did not apply to those who are on unlimited or tiered plans.

Comedian Bill Hader is adept onstage and doing live performances. But he's scared to death of standup.

He says he remembers watching Chris Rock's 1996 HBO special, Bring the Pain, and thinking, "I don't know how people do that."

"I need a character," Hader tells Fresh Air's Terry Gross. "I need people out there with me."

So Hader has stuck with sketch comedy — where he has been wildly successful.

JD McPherson's "big break" came when he introduced himself to producer and bassist Jimmy Sutton of The Four Charms via MySpace. After receiving several of McPherson's demos, Sutton immediately recognized his talent, and the Oklahoma native moved to Chicago to begin recording with Sutton. The pair released a music video for "North Side Gal," which became a viral hit.

More Latino students are enrolling in college now than ever before, according to a report by the Pew Hispanic Center. But Latinos still lag behind other groups in preparing for and completing college. Guest host Viviana Hurtado discusses the report's findings with Richard Fry of the Pew Hispanic Center and the College Board's Jim Montoya.

A 2.3 percent increase in sales of previously owned homes in July from June is the latest sign that the housing market is on the mend, Reuters reports.

The National Association of Realtors said this morning that sales of existing homes increased to a seasonally adjusted annual rate of 4.47 million.

When astronomers survey the universe, the landmarks are galaxies, those gigantic agglomerates of stars and interstellar gas spread across the immensity of space. A typical spiral galaxy, like our own Milky Way, boasts hundreds of billions of stars grouped along hundreds of thousands of light-years. That means that it takes a beam of light all that time to go from one extreme of the galaxy to the other, traveling, as light does in a vacuum, at 186,282 miles per second.
