(CNN) -- X-ray data from NASA's MESSENGER probe points to high levels of magnesium and sulfur on the surface of the planet Mercury, suggesting its makeup is far different from that of other planets, scientists say. The unmanned orbiter has been beaming back data from the first planet for a year and a half. Readings from its X-ray spectrometer point to a planet whose northern volcanic plains formed through upwellings of rocks more exotic than those often found on the Earth, the Moon or Mars, said Shoshana Weider, a researcher at the Carnegie Institution of Washington. "Before this MESSENGER mission, a lot of people assumed it was very like the Moon -- it's dark, it's grey," Weider said. But while the Moon's surface formed when light materials floated to the top of an ocean of molten rock, the low level of calcium on Mercury indicates that didn't happen there.NASA probe gives insight into Mercury's formationThe surface has sulfur levels 10 times higher than Earth'sThe MESSENGER orbiter has been circling Mercury since March 2011

Atlanta (CNN) It's 3 o'clock on a Monday afternoon in Clarkston, Georgia, and Dr. Heval Mohamed Kelli is smiling ear to ear. He looks on as a group of overachieving Clarkston High School students file into a science classroom to receive their after-school lesson for the day. Kelli rubs his hands in anticipation and then he pauses, if only briefly, to look down. He stares at his hands, the same hands he used to wash dishes when he arrived to the United States in 2001. Kelli remembers how they would wrinkle like a prune from being under water for too long while working at the first job he had in the US as a Syrian refugee.Heval Kelli mentors students, many of them refugees, at high school he attendedIt's all about encouraging the American Dream, Syrian refugee says

(CNN) Omar Abdel-Rahman, the Egyptian cleric who inspired terrorist plots in New York during the early 1990s and who died in an American prison on Saturday, was also the spiritual guide of key 9/11 plotters. More specifically, he was the source of a laminated card of Arabic script that is critical to understanding why nearly 3,000 Americans lost their lives on the morning of September 11, 2001. The Arabic on the card reads: "A fatwa [religious ruling] of the captive Sheikh Omar Abdel Rahman ... To all Muslims everywhere: Destroy their countries. [The Americans, Jews and Christians]. Tear them to pieces. Destroy their economies, burn their corporations, destroy their businesses, sink their ships and bring down their airplanes. Kill them in the sea, on land and in the air."On Saturday, Egyptian cleric Omar Abdel-Rahman died in an American prisonPeter Bergen: Rahman was the inspiration behind some of the worst modern terrorist attacks, including 9/11Bergen: His death will almost certainly spark calls from al Qaeda leaders for further anti-American attacks
