The U.S. and other major powers have been holding historic negotiations with Iran to try to curb that country's nuclear program. But Washington still has many other concerns about Iranian behavior. And while some diplomats may hope to build on the nuclear talks to push Iran to play a more constructive role in the region, experts remain skeptical.
Karim Sadjadpour of the Carnegie Endowment for International Peace says there are a couple of ways to look at the negotiations with Iran.
Puddled meltwater very likely primed this ancient edge of the Antarctic's Larsen Ice Shelf to rapidly disintegrate over just several weeks. This view of the splintered mix of frozen bergs is from a Feb. 21, 2002, satellite image.
An expert panel at the National Academy of Sciences is calling for an early warning system to alert us to abrupt and potentially catastrophic events triggered by climate change.
The committee says science can anticipate some major changes to the Earth that could affect everything from agriculture to sea level. But we aren't doing enough to look for those changes and anticipate their impacts.
Keith Jarrett is a jazz legend. His catalog of recordings includes solo piano improvisations, trio and quartet works, classical performances, early sessions with Charles Lloyd and late ones with Miles Davis. But there's nothing quite like Jarrett's new double-CD set No End: It was recorded in his home studio in 1986, and he plays all the instruments — notably drums, bass and electric guitar.
Televangelist Paul Crouch, co-founder of the Trinity Broadcasting Network, died Saturday at the age of 79. The Pentecostal minister's broadcasting network came to be the world's largest Christian television system with Praise-a-Thon fundraising efforts that brought in as much as $90 million a year in mostly small donations.

The grass- and weed-strewn interior of the Church of St. John the Baptist — housed inside the Stoudios monastery — has gone to seed. An ambitious restoration project is due to begin next year, when it will open to the public as a mosque, according to the government.

Recent remarks by a Turkish official have rekindled talk that the Hagia Sophia may be reconverted into a mosque. The most famous Byzantine structure in Istanbul, it was built as a Greek Orthodox church in the fifth century, became a mosque in the 15th century, and has been a museum since 1935. Other Christian sites are already being converted into mosques.
A historically significant but now-crumbling fifth century Byzantine monastery in Istanbul is finally slated for restoration. But for Turkey's dwindling Greek community, the bad news is that the government wants to turn the Stoudios monastery into a mosque.
It's just one of several such conversions of historically Christian sites that the government is considering. And there's even talk that the Hagia Sophia, the most famous Byzantine structure in modern Istanbul, will be reconverted into a mosque.

Egypt's Mohamed Yousef won a gold medal at the kung fu championships in Russia in October. He then put on a yellow T-shirt with a four-finger salute to express solidarity with protesters opposing Egypt's military-backed government. Egyptian sports officials have suspended him and barred him from tournaments for a year.
Mohamed Yousef is a tall, handsome practitioner of kung fu. In fact, he's an Egyptian champion who recently won an international competition.
But a month ago, when he collected his gold medal at the championship in Russia, he posed for a picture after putting on a yellow T-shirt with a hand holding up four fingers.
That's the symbol of Rabaa al-Adawiya, the Cairo square where Egyptian security forces opened fire in August on supporters of ousted Islamist President Mohammed Morsi. Hundreds were killed, including seven of Yousef's friends.
Governments around the world have agreed to limit global warming to 2 degrees Celsius (3.6 degrees Fahrenheit). That would require an 80 percent reduction in energy sources like coal, oil and natural gas, which emit carbon dioxide into the air.
Nations are far from that ambitious path. There are big political and economic challenges. But technologists do see a way — at least for the United States — to achieve that goal.
The World Health Organization has declared a polio emergency in Syria.
After being free of the crippling disease for more than a decade, Syria recorded 10 confirmed cases of polio in October. Now the outbreak has grown to 17 confirmed cases, the WHO said last week. And the virus has spread to four cities, including a war-torn suburb near the capital of Damascus.
This week, a group of Seminole Indians in Florida is commemorating an important historical event — when a Seminole named Polly Parker organized and led an escape from federal troops more than 150 years ago.
It came at a time when Indians were being deported to the West in what became known as the Trail of Tears. Florida's Seminoles call themselves the "unconquered people" because, through three wars with federal troops, they resisted deportation to Indian Territory west of the Mississippi.
Workers process applications for Oregon's health exchange program. The state paid tech giant Oracle to build its online exchange, but with the site still not functional, people shopping for insurance have been forced to apply on paper.
Oregon has spent more than $40 million to build its own online health care exchange. It gave that money to a Silicon Valley titan, Oracle, but the result has been a disaster of missed deadlines, a nonworking website and a state forced to process thousands of insurance applications on paper.
Some Oregon officials were sounding alarms about the tech company's work on the state's online health care exchange as early as last spring. Oracle was behind schedule and, worse, didn't seem able to offer an estimate of what it would take to get the state's online exchange up and running.
Transportation officials are investigating what caused a Metro-North Railroad passenger train to derail along the Hudson River in New York on Sunday morning. The crash left four dead and injured dozens more.
Thousands of Ukrainian protesters blockaded government buildings in Kiev Monday seeking to oust President Viktor Yanukovich. Demonstrations over the weekend drew as many as 350,000 people in the largest rally since the Orange Revolution. The protests came after Yanukovich decided to abandon a trade deal with the European Union and instead seek closer ties with Russia. Robert Siegel talks to Steven Pifer, former U.S. ambassador to Ukraine, about the political landscape in the country and its relationship with Moscow.
A former Amazon executive who helped Jeff Bezos turn shopping into a digital experience has set out to end illiteracy. David Risher is now the head of Worldreader, a nonprofit organization that brings e-books to kids in developing countries through Kindles and cellphones.
Risher was traveling around the world with his family when he got the idea for Worldreader. They were doing volunteer work at an orphanage in Ecuador when he saw a building with a big padlock on the door. He asked a woman who worked there what was inside, and she said, "It's the library."
