This satellite image of Sudan was made available by the Satellite Sentinel Project in 2011. It appears to be a mass grave, offering the first aerial photographs from a conflict zone that outside observers can't access.
Here are two things you don't often hear mentioned in the same sentence: social media and nuclear weapons.
Rose Gottemoeller, acting undersecretary of state for arms control, quickly links those two unlikely partners in conversation. She's behind a campaign to discover how new communications tools can help rid the world of some of the dangers of nuclear weapons.
Crowdsourcing Nuclear Problems
Gottemoeller is an avid user of Twitter, and it made her wonder how Twitter and other methods of crowdsourcing a problem can help her in her work.

Children play in a traditional residential district in Beijing that is undergoing demolition, in April 2011. Despite public protest, historic and new homes are being destroyed all over the city to make way for development.
Down a quiet Beijing alleyway on a recent day, as the winter wind whistles, two men stand guard over a pile of bricks hidden behind a corrugated iron fence.
The pile of rubble was once the home of the man known as the father of modern Chinese architecture, Liang Sicheng. The Orwellian reason for its demolition? "For maintenance," according to a Xinhua news agency report, citing the developer, Fuheng Real Estate company.
Morning Edition has been asking people what music makes them move, in order to create The Ultimate NPR Workout Mix. The mix already includes a good selection of Kanye West, 2Pac and Madonna — which is just fine for some people.
The Earth's continents are in constant motion. On at least three occasions, they have all collided to form one giant continent. If history is a guide, the current continents will coalesce once again to form another supercontinent. And a study in Nature now shows how that could come about.
You can think of continents as giant puzzle pieces shuffling around the Earth. When they drift apart, mighty oceans form. When they come together, oceans disappear. And it's all because continents sit on moving plates of the Earth's crust.
Republican presidential candidate Mitt Romney's losses on Tuesday, while not very meaningful in the race to accumulate delegates, have raised questions once again about his ability to inspire passion from his party's base and about his viability in the general election.
Rival Rick Santorum's victories in Colorado, Missouri and Minnesota dealt a setback, if not exactly a body blow, to Romney — whom Santorum routinely dismisses as a candidate with a big machine but no core.
Ask Detroit teachers about their biggest challenge and many will say, "You can't teach kids who don't come to class." Last year, the average Detroit public high school student missed at least 28 days of school.
Now, as part of its effort to get parents more involved, the district has launched a major initiative to improve attendance. The effort includes parent workshops and attendance agents charged with pushing parents to send their kids to school every day.
Mother and calf common dolphins are transported to the beach by a team from the International Fund for Animal Welfare and the New England Aquarium before being released back into Cape Cod Bay on Jan. 14. So far, area rescuers have counted 147 dolphin strandings this winter alone.
Dolphins have been stranding themselves along the shores of Cape Cod, Mass., since the Pilgrims' times, and this winter is no different. What is different is how long the latest round of strandings has lasted — almost a month. So far, rescuers have counted 147 strandings and 38 successful rescues and releases.

"Kot" (left) and "Schumacher," members of the feminist collective, say their group will be staging more illegal anti-government performances around Moscow in the weeks leading up to the March 4 presidential elections. They say they were galvanized originally by their opposition to government policies against women.
Anti-government protests in Russia are taking many different forms, from mass rallies and marches to defiant street art and music.
Just recently, members of a feminist punk group were arrested in Moscow's Red Square after they performed a song ridiculing Prime Minister Vladimir Putin. The group, which calls itself Pussy Riot, says it's planning more stunts before March's presidential elections.
