Question: On a day when Chris Froome has never been under greater scrutiny, when everything from his heart rate to his power output is being used as evidence against him, he responded by delivering a performance so astonishing he might just have this Tour de France won after 10 days.

Question: Washington (CNN) North Korea might not be able to reach the U.S. mainland with a nuclear weapon yet, but the political fallout from its claimed hydrogen bomb test is here already. Even before the shockwaves of the 5.1 temblor triggered by Tuesday's test wore off, Hillary Clinton was fighting off a volley of Republican attacks, GOP presidential candidates were talking tough and Donald Trump jumped on a chance to chastise China. The episode was a fresh indication of the challenge that Clinton faces in running for the White House on her record as secretary of state, which makes it impossible for her to escape deficiencies in President Barack Obama's national security legacy.The episode is a fresh indication of the challenge that Clinton faces in running for the White House on her record as secretary of stateWashington has tried punishment and inducements repeatedly with North Korea and has failed to change its calculations

Question: (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
