[EX Q]: (CNN) Since the discovery of dark streaks on the slopes of Mars in 2011, astronomers have been excited about potential evidence of water beneath the surface of the red planet. If there are subsurface water flows on Mars, they could allow life -- even on a microbial level -- to exist as well. But further study of these recurring slope lineae, known as RSL, is revealing something else. Those dark streaks may be the result of granular flows like sand and dust, according to a study published Monday in the journal Nature Geoscience. The study is the product of a research team made up of representatives from the US Geological Survey, the Planetary Science Institute, the University of Arizona and Durham University in England.The flows correlate more with sand on active dunes rather than subsurface waterResearchers studied flows at 10 sites

[EX Q]: Near Simferopol, Ukraine (CNN) -- In the wake of Russia's invasion of Crimea, the mood here Tuesday was tense, but the streets appeared eerily calm. Ukraine's Crimea region has become the flashpoint in a geopolitical crisis that has embroiled London, Washington, the United Nations and NATO. In the days since they crossed the border into this strategically important peninsula on the Black Sea, Russian forces have surrounded 10 Ukrainian military bases -- 16,000 troops in the past week, according to Ukrainian officials. There has been no fighting -- or loss of life -- but there were ample signs of preparation.NEW: A supporter of Ukrainian forces says talks, not fights, will solve problemsRumor, confusion and outlandish claims mix freely in Crimea's capital"Mother, I'm sorry I had to go," reads poem at memorial in Kiev's Independence SquareProtesters in Kiev say they are outraged, willing to fight Russian troops

[EX Q]: The inquest will be long, weary and painful. Yet the reasons Celtic suffered a second successive Champions League exit under Ronny Deila were not hard to find. On a night when they needed discipline, calm and composure, Scotland's champions contrived to make a pig's ear of it. Malmo not only had the mouth. They also had the trousers. Over two games against a modest team, Celtic's defending was dismal. Shipping three goals from corner kicks, the zonal marking was wretched. In their past five games, Deila's side have now lost nine goals, 28 in their past 18 European matches in all. The Achilles' heel is clear, brutally exposed once more to the naked eye here.Celtic failed to reach the lucrative group stage of the Champions League after losing in SwedenMarkus Rosenberg opened the scoring for the home side with a header in the first halfCeltic's Leigh Griffiths was fortunate not to see red for appearing to knee an opposition player in the privatesThe visitors had a goal disallowed when Nir Biton found the net but the referee incorrectly ruled a handballFelipe Carvalho added a second 10 minutes after the break to double Malmo's advantage
