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.

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.
