  1. Re:Cheers for PETA on Scientists Create Artificial Meat · · Score: 1

    While I agree with you I think equating consciousness with a CNS is kind of closed minded, Im mostly thinking about all the possible weird aliens and AI here. I mean having the decision making part of you centralized makes it easier to protect and speeds up communication, but if the environment was less hostile towards the organism for whatever reason and there wasnt such a premium on quick decision making (the organism could even still have a good set of preprogrammed unconscious reflexes to get out of harms way or get sustenance or whatever) it wouldnt be that far fetched to have evolution come up with a system in which the decision making cells were more spread out, maybe even communicating with bioluminescence or fluorescence or something to speed everything up.

    You could try to just it in some solution that you pulse a nicotinic agonist into (carbachol maybe, you would want one with low affinity but long halflife in the tissue) followed by some sort of wash solution (maybe with a low affinity antagonist), then repeat with the original agonist solution. I have no idea how easy it would be to engineer such a setup though, especially at industrial levels.

    Well youre using telegraphic speech, only including the sounds most important in conveying your meaning. I think the reason for this is that it raises the signal to noise ratio by limiting the number of sounds the non-native speaker needs to decode, allowing them to fill in the missing pronouns, etc after youve said whatever it is youre saying, rather than doing it as your making the important sounds(the signal).

    (the noise=processing of possible interpretations of that sound, the size of the set will vary inversely with how familiar you are with the language)

    You could look at animals as sort of "less-evolved" humans, in that humans are the only conscious beings we really know of for sure. I mean go far back enough and youd find an ancestor who was no more conscious than that cow you ate part of for lunch. How "conscious" are fetuses or even newborns? Relative to a cow or chicken or really insert any living thing you wouldnt make a fuss about killing if it was inconveniencing you to not kill it. I'm not a vegetarian, mostly because I dont think one person would make a difference in something that big at this point in Human culture at least, but if you're someone really really cares about that 12 week old fetus... Id think it would be consistent to also be strongly against unnecessary killing of other animals (the more like humans the animal is the moreso you should feel that way).

    Use of those terms also confuse the issue... it sounds as if some people are going around advocating forced abortions or something.. The truly correct terminology would be Pro-law-against abortion and Anti-Law-against abortion. If someone could figure out a way to make that more catchy noone would have an excuse for using the terms derived from political spin.

  11. Re:Doesn't worry me on How Terahertz Waves Tear Apart DNA · · Score: 1

    So I dont really understand whats supposed to be going on here. What is absorbing the energy of the photon, and what does resonance have to do with it? To give you an idea of where Im coming from:

      So you have your dsDNA, both strands connected to each other by all those hydrogen bonds... which is basically saying protons are being held between two electrons (one from each complimentary base nitrogen or oxygen) and its energetically unfavorable for the proton to move elsewhere. But of course everything is vibrating around so youll be getting things like changes in the distance the proton is from either Nitrogen or Oxygen of the nucleotides, or changes in the angle at which it sits relative to them, etc. These "vibrations" would be constantly happening, and obviously be also affected by the movements of every other bond (hydrogen, covalent...ones that connecting together the nucleotides, water molecules, all of them) surrounding it. So these vibrations are going to have a certain amount of energy associated with them... so the 2 Terahertz photons have an energy that corresponds to some vibrational energy involved at this level? The way I understand it EM radiation interacts with matter by causing electrons to move farther away from nuclei, this movement of electrons away from and then back towards nuclei and rotation of the molecules the nuclei are part of relative to other nuclei would also be the ultimate causing the vibrations to begin with. So then could you say that that the 2 THz photons are increasing the likelihood of a certain one of these vibrations will occur (for example a push of a proton close enough to an Oxygen on one nucleotide, and thus farther away from the Nitrogen on the complementary nucleotide leading to a breaking of the hydrogen bond) but the 2 THz photon will only get absorbed when that proton is in a certain position relative to the other nuclei, and since its position is in constant flux according to some nonlinear pattern, significant effects will only be seen if a series of 2 THz photons keep hitting it at just the right pattern of timing...

    Im not sure if that makes sense or not but yea, some sort of physical explanation would be nice.

    Smoking cigarettes makes it less likely you will ever get parkinsons (source). Which chemical is it, nicotine, harmaline, what? At first noone knew... its probably nicotine. How is it doing this? Theres a crapload of different versions of nicotinic receptors, is somehow interacting with a specific protein that makes up one of them (seems most likely) or even sticking to some other thing in your body and changing what that protein/whatever does (less likely)? Probably nicotinic receptors... which kind? Theyre made of combinations of 5 different proteins that arrange together to form the receptor, theres 17 proteins that could be part of these that could theoretically arrange in any combination you want...someone had to narrow down the possibililties. So ok theres only like 6 different combinations of these subunits we find in the parts of the brain that are supposedly involved in parkinsons (knowing which parts were involved was its own whole multimillion dollar expenditure) which one (or maybe more than one) of those is what nicotine is interacting with to make smokers less likely to develop Parkinson's? Probably ones containing a4B2 (alpha4 and beta2 are names for 2 of the 17 possible subunits). Whats special about those? What type of neurons are they located on? Is nicotine doing this at the cell surface... or getting into the cell and doing something before these receptors even reach the surface? Is it increasing synthesis of these, or decreasing degradation? Where exactly is it sticking... how is the binding site shaped and what amino acids are involved... and what chemical and structural properties should a chemical have to make this anti-parkinsonian effect happen?

    Once you know that, you can design a drug to fit, but then you also want to figure out how to make it also have chemical and structural properties that make it not altered to some nonfunctional form by your liver enzymes, pass the blood brain barrier, etc, that way people can just down a pill rather than get shots... or worse need to get the drug injected into their central nervous system in some way.

    Its all very boring to anyone who doesnt like a good, complex mystery... but someone should be doing it because there are ways to figure out each step of the way (it might take a couple years and a bunch of money but its doable). And this isnt even my field.
