Fox news article claims in the headline that evidence of past life was found on Mars. Before you get too excited, it wasn't, and the article even ends up saying So, what the article's headline is getting at, is that NASA found traces of elemental boron on the Martian surface. The article then notes that borate compounds are present in some of the macromolecules used by organisms to process ribonucleic acid. Then the article makes the huge leap that this logically means that life existed on Mars. Next, the article quotes someone from NASA saying there is no evidence of ancient life on Mars. Finally, the article throws us a red herring about Space X and Elon Musk. Nice logic, Fox. http://www.foxnews.com/science/2017/09/07/life-existed-on-mars-shocking-discovery-suggests.html This is just about equivalent to finding evidence of nickel in the spectrum of a distant star and concluding that it means that there are people there playing electric guitar, "because nickel wound strings, duh."
