  1. Re:neat on Liquid Crystal Phases of DNA, Beginning of Life? · · Score: 1

    some strands of genetic material are catalytic- the point is that genetic material isn't just information encoding, it also can act as a part of the cellular machinery its self. it catalyzes its own cleaving, acts as a primitive amino acid string ribosome and catalyzes the formation of other molecules. only later do these molecular systems evolve into what we now would recognize as a functional genetic system based on DNA or RNA as the main carriers of information. is it efficient? no, not really, it is quite slow but it is an example of a very rudimentary evolutionary system that can replicate and select for DNA/RNA strands that are better than those before them. a strand of RNA that can catalyze its own replication will outcompete one that is slower- mutations happen constantly since the whole system has little in the way of genetic repair yet so things change fast. modern day ribosomes are composed of RNA and protein, this is probably an evolutionary fossil from the first "ribosomes" that strung amino acids together. for example, amino acids self assemble in the presence of higher temperature and acidity into apo-proteins which are by themselves catalytic. it is likely that these apo-proteins or any polypeptides associated with nucleic acids under conditions that later evolved into primitive ribosomes. at first these complexes probably speed up the rate and accuracy by which genetic material is replicated and further down the line had a dual purpose- to systhesize its self more efficiently and then the evolution of a genetic system with a small number of base pairs acting to encode for amino acids directly ratehr than catalyzing the synthesis and stringing together of polypeptides. specialization leads to better efficiency and eventually other components of the cell are synthesized and evolve over millions of years to form the first bacteria.

    "The key observation with respect to early life is that this aggregation of nano DNA strands is possible only if they form duplexes," Clark said. "In a sample of chains in which the bases don't match and the chains can't form helical duplexes, we did not observe liquid crystal ordering."

    The CU-Boulder and University of Milan team began a series of experiments to see how short the DNA segments could be and still show liquid crystal ordering, said Clark. The team found that even a DNA segment as short as six bases, when paired with a complementary segment that together measured just two nanometers long and two nanometers in diameter, could still assemble itself into the liquid crystal phases, in spite of having almost no elongation in shape. Subsequent tests by the team involved mixed solutions of complementary and noncomplementary DNA segments, said Clark. The results indicated that essentially all of the complementary DNA bits condensed out in the form of liquid crystal droplets, physically separating them from the noncomplementary DNA segments. "We found this to be a remarkable result," Clark said. "It means that small molecules with the ability to pair up the right way can seek each other out and collect together into drops that are internally self-organized to facilitate the growth of larger pairable molecules. "In essence, the liquid crystal phase condensation selects the appropriate molecular components, and with the right chemistry would evolve larger molecules tuned to stabilize the liquid crystal phase. If this is correct, the linear polymer shape of DNA itself is a vestige of formation by liquid crystal order."
    one of the requirements for life is that you have an environment that supports molecular self assembly and recognition, this experiment seems to show that this is the case with DNA and RNA strands as short as 6 bases and can select for more stable configurations over time. It's the beginnings of evolutionary natural selection- base pairs assemble into structures that have certain desireable characteristics.

  7. Re:Will it ever stop? on Comcast Targets Unlicensed Anime Torrenters · · Score: 1

    I bet Comcast didn't set a solid cap because it's probably based on a bell-curve of data usage. they try to keep the mean under a certain amount and so if the higher 10% or so of customers use 30% of the data for example, telling them to throttle back is an easy way to decrease Comcast's bandwidth obligations. They can't really tell anyone what the solid cap is because there'd be enough people maxing out what they can get away with under that solid cap and it wouldn't solve much under their current system. As to why they don't say you can use x gigs/month for x dollars, it's probably more profitable for them to sell "unlimited" contracts at a certain price that allows for most people's bandwidth needs and provide them with a nice cushy profit margin as well.

    Of course once she finds a way to escape, the addiction will be back... A lot of people who are "addicted" to the internet don't really have any alternatives that they consider better than browsing the web except of course, finding people that understand them in real life. They'd do just as well fixing the problem by finding friends for addicts if nothing other than to hang out with and actually do something in real life. I mean heck, most would probably settle for other geeks like them with similar problems [internet addiction for one?] and it doesn't need to be in some technology-free camp either.

    The next step in addressing the issue of genetic discrimination was taken by President Bill Clinton. The President had earlier supported proposed legislation that would have banned all health plans - group or individual - from denying coverage or raising premiums on the basis of genetic information. When the legislation failed to pass Congress, President Clinton issued an executive order ( Executive Order 13145 to Prohibit Discrimination in Federal Employment Based on Genetic Information) in February 2000 prohibiting agencies of the federal government from obtaining genetic information about their employees or job applicants and from using genetic information in hiring and promotion decisions.
    Suppose you get a genetic test that at the time shows nothing abnormal so you get your insurance coverage, then a few years later it is shown that you do indeed have a risk for a certain disease- you could very well lose your insurance or at the least have to sell a kidney to get any insurance. http://en.wikipedia.org/wiki/Genetic_discrimination
