Liquid Crystal Phases of DNA, Beginning of Life?

An anonymous reader writes "A team led by the University of Colorado at Boulder and the University of Milan has discovered some unexpected forms of liquid crystals of ultrashort DNA molecules immersed in water, providing a new scenario for a key step in the emergence of life on Earth. CU-Boulder physics Professor Noel Clark said the team found that surprisingly short segments of DNA, life's molecular carrier of genetic information, could assemble into several distinct liquid crystal phases that "self-orient" parallel to one another and stack into columns when placed in a water solution. Life is widely believed to have emerged as segments of DNA- or RNA-like molecules in a prebiotic "soup" solution of ancient organic molecules.

    We're plenty intelligent enough... we just don't have enough data and probably never will, but we can make guesses - more educated guesses than those made by early philosophers (religious academics and natural academics). Personally I don't see the disconnect between early science/religion and modern science. They sought answers with what information they had available.. we do the same. Just because some cult of people want to believe that we were at the pinnacle of understanding some 2 - 3 thousand years ago, doesn't discount the efforts made at the time.

    Those Rabbis, Greeks and monks were very smart people - they also had to deal with politics and ignorance however and sometimes the best way to deal with that is to dumb it down to a lowest common denominator. "That's right, God made that happen. Don't go to war over it... it was a miracle. Now give us money so we can keep teaching your kids how to read/write and count to ten."

    I'm personally of the opinion that nothing science concludes will ever be able to prove or disprove the existence of (a) God(s), so I'm not sure why this discussion keeps coming up.

    It keeps coming up because religious ideologues keep insisting that science is wrong because it contradicts their beliefs. And they want to base public policy and education on those beliefs. The beliefs themselves are a personal matter, of course, and they've got every right to believe that Rapture is imminent or that life was created in its current form 6000 years ago; the conflict occurs when they try to base things like environmental management or what's taught in high-school science classes on it.

    Honestly, the religion bashing is completely pointless and is getting really, really old hat.

    The science bashing isn't pointless at all -- it's a means of gaining political power -- but it's definitely old hat, which doesn't keep fanatics from doing it. Scientists who bash religion, e.g. Dawkins, do so out of disgust with religion's continual insistence on trying to replace knowledge with ignorance, and the consequences thereof.
