It gives a different perspective of how salts dissolve in water. The magnesium perchlorate is clearly a major contributing factor on the freezing point of this solution and paves the way for understanding how a fluid might exist under the sub-freezing conditions of Mars&#8221;.<\/li>\n<\/ul>\n<p><strong>Reference:<\/strong><br \/>\n<a href=\"http:\/\/ddnews.gov.in\/sci-tech\/new-study-analyses-water-structure-and-possibility-life-mars\" target=\"_blank\" rel=\"noopener\">http:\/\/ddnews.gov.in\/sci-tech\/new-study-analyses-water-structure-and-possibility-life-mars<\/a><br \/>\n<a href=\"https:\/\/www.sciencedaily.com\/releases\/2017\/10\/171013091028.htm\" target=\"_blank\" rel=\"noopener\">https:\/\/www.sciencedaily.com\/releases\/2017\/10\/171013091028.htm<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A team led by Dr Lorna Dougan from the University of Leeds has analysed the structure of water in a magnesium perchlorate solution &#8212; what they refer to as &#8220;mimetic Martin water&#8221; &#8212; to better understand how the liquid could exist on the Martian surface.
