Example Input: (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

Example Input: (CNN) Scotland will likely seek independence for a second time this decade after the historic vote for the United Kingdom to leave the European Union, Scottish First Minister Nicola Sturgeon said Friday. Sturgeon's Scottish National Party was elected on a platform that vowed, in part, to revisit the independence issue -- last decided in a failed 2014 referendum -- should the country be "taken out of the EU against our will," Sturgeon said. "Scotland does now face that prospect," Sturgeon said. "It is a significant and material change in circumstances, and it is therefore a statement of the obvious that the option of a second referendum must be on the table, and it is on the table."Scottish First Minister Nicola Sturgeon's party has vowed to revisit independence issueIndependence rejected in 2014, but with UK vote on EU, things have changed, she says
