      DNA Found in Meteorites

      DNA Found in Meteorites --New Research Views them as Molecular Tool Kits that Provided the Building Blocks for Life

      This is awesome, and has pretty huge implications. It's been speculated before, but it's nice to see that the idea has a lot more evidence going toward it.

      Nah it doesn't. The article is a typical hunk of junk, I literally only got two words in before facepalming. I cannot stand the hyperbole that journalists put into headlines about science; it isn't even hyperbole, it's just plain lying, in this case and many others.

      They have found a jumble of various nucleobases. These are the basic types of single molecules that are used to form genetic material like RNA and DNA. But in no sense have they found DNA, which is much more refined and complex and would be a truly bizarre and revolutionary discovery.

      There isn't really anything that can be deduced from this, either. It just highlights previous (and genuinely fascinating) discoveries, which have shown that the molecules for life can in fact arise spontaneously and with relative ease, and would indeed have done so in what is thought to be Earth's early atmosphere:

      Miller

      These include amino acids, which are really the central molecules of life and are 'what DNA bosses around', and indeed nucleobases such as those found on this meteor; adenine, for example, can form when hydrogen cyanide and ammonia, two extremely basic compounds, react in water. So hopefully you see the point; contrary to what is implied by the article, all this shows is that the molecules that life on Earth is based on form spontaneously, and by no means does this just happen on meteoroids; they are not some kind of mysterious and holy entity spreading life through the universe. Indeed most of the original molecules were probably born and raised here on Earth, by the obvious virtue it has of being much much bigger.

      Oh, awesome! In the true sense of the word.

      We were once nucleobases on a meteorite.

      I still don't know why they have to make shit up for the titles always. They did not find DNA.

      Isn't it amazing enough without adding bullshit hype to it?

      EDIT: Damn you Xei. And I didn't think about that second bit, very true.

      True enough. Here's where they got the information:
      Meteorites: Tool kits for creating life on Earth | Carnegie Institution for Science

      ...which clearly doesn't say anything about it being actual "DNA." Agreed that the title is very misleading.

      News this important isn't to be believed unless it comes straight out of NASA or something.

      And even then, that doesn't prove much, assuming they continue to hold press-conferences without having done basic tests like they did last year with that "arsenic-based lifeform" crap.

      That was mostly media reporting errors. Just like this article.

      Not really, the actual 'science' was terrible and ripped to shreds in the NASA case throughout the scientific community. It wasn't poor reporting, it was just very very bad science.

      This case is definitely just silly reporting, as you say.

      Sorry yeah I remember that now. I was half-thinking of the other meteorite NASA found with bacteria on it.
