Transition Metal Catalysts Could Be Key To Origin of Life

An anonymous reader writes "One of the big, unsolved problems in explaining how life arose on Earth is a chicken-and-egg paradox: How could the basic biochemicals — such as amino acids and nucleotides — have arisen before the biological catalysts (proteins or ribozymes) existed to carry out their formation? In a paper appearing in the current issue of The Biological Bulletin, scientists propose that a third type of catalyst could have jumpstarted metabolism and life itself, deep in hydrothermal ocean vents."

    you wouldn't start with citric acid and some simple metal, like iron or copper, you'd have to use something more serious. I imagine AsO(OH)3 (arsenic acid) mixed in some proportion with Strontium and Tin. I think that's how you get Beck.

    That's a non sequitur, and you know it! Beck is one of the undead, so you can't apply the same rules to him.

    It is a good choice and happens to be atomic number 42. Google 42 if this number doen't meaning anything special to you.

    Why hasn't Glen Beck denied being a zombie yet? Why won't Glenn Beck deny these allegations? We're not accusing Glenn Beck of eating brains and feasting on the dead - in fact, we think he didn't! But we can't help but wonder, since he has failed to deny these horrible allegations. Why won't he deny that he is a zombie and that he feasts on human beings?
