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: You could have been forgiven for mixing up which line-up cost £230million. Long-time Premier League title favourites Manchester City were comprehensively undone by the Stoke City pair of Marko Arnautovic and Xherdan Shaqiri, whose combined price tag of £15million was half what Manuel Pellegrini paid for holding midfielder Fernandinho alone. Arnautovic scored twice inside the first 15 minutes, both brilliantly assisted by Shaqiri, as Pellegrini's side drifted badly in the swirling Britannia cross-wind. Without Vincent Kompany, Pablo Zabaleta, Yaya Toure and Sergio Aguero – all injured – the richest club in England looked bereft of leadership. Centre halves Martin Demichelis and Nicolas Otamendi rarely looked like they inhabited the same planet, let alone being team-mates for Argentina.Marko Arnautovic fired Stoke City ahead from close range on seven minutes after Xherdan Shaqiri's crossArnautovic doubled the Potters lead on 15 minutes with a neat finish following from Shaqiri's brilliant through ballStoke's No 10 came inches to scoring a first-half hat-trick before the interval but his strike hit the postVisitors played the final 16 minutes with 10 men after Fernando was forced off with a hamstring injury

Example Input: Paul Eisen, the self-professed Holocaust denier, has given Jeremy Corbyn his support in an extraordinary blog post in which he says that he has been close to the Labour leadership contender for more than 15 years.

'I was just beginning to establish Deir Yassin Remembered [a controversial, pro-Palestinian pressure group] in the UK and I wanted him to join. 'I'd hardly begun my feverishly-rehearsed pitch before his cheque book was on the table. 'From that day on, without fuss or bother, whether DYR was flavour-of-the-month or the maggot-at-the-bottom-of-the-food-chain, he attended every single Deir Yassin commemoration.'Paul Eisen, a self-professed Holocaust denier, says that he has been close to Corbyn for more than 15 yearsHe has come out in support of Corbyn's campaign on his blogEisen wrote that Corbyn has attended 'every single' one of his annual events and has even donated money to his anti-Israel pressure groupEisen's group is seen as so extreme that it was disowned by the mainstream Palestinian Solidarity Campaign in 2007Corbyn has been sympathetic to Hamas, Hezbollah and the IRA in the past
