  1. By 2025 we will be able to create a molecular model of a human being, from egg to adult organism, in realtime, and the rate at which a human can be modelled increases exponentially thereafter. 50 years would place us some 30 years after this happens. I would say in 50 years we will not only know everything about the brain/consciousness, but we will have dramatically improved upon it to such a degree that consciousness at that point in time is simply incomprehensible (i.e. the Singularity). Kurzweil predicts that by 2045 a $1000 computer will be a billion times as powerful as all brains on earth.

     

    That's a bit opptimistic. What source claims we can "know everything about the brain" in 20 years? We will definitely know volumes more than we do now, but knowing everything?

  2. We have had several wars since WWII without Congress declaring war. Blind trust in any organization, particularly an advocacy group such as the ACLU, is no better than blind trust in the President.

     

     

    Actually, we haven't had an offical war since WWII. Korea was a "police action" and I think Vietnam also had some sort of euphenism as well.

     

    Also, I agree with Bascule in that I'll go with the ACLU's choice. I won't blindly trust them, but on matters of law I think they have some authority.

  3. 2. Memory research is another area I expect great progress in. In addition to better therapies for disorders like alzhiemer's, this research will also improve our knowledge about how memories are formed and how they influence decision making.

     

     

    I agree that research in memory and the neural processes associated etc, will really leap forward in the coming half-a-century. But I think the change will sort of be in the opposite direction; I belive research will focus on how to remove memories. People with PTSD especially could benefit from therapies that remove or deaden memories.

     

    This is being researched now, and there was a New Scientist article about it a few months ago. Here's a link (subscription needed but at least you can see it's there): http://www.newscientist.com/channel/health/mg18825281.200

  4. Well' date=' there really is no reason for corporate adoption to even be a factor. Truman could have been Christof's own son for all intesive purposes in the movie, without it making a difference.

     

    You could propose the child is being forced to work, due to being on the TV set 24 hrs a day. If it was filmed in the Caymen Islands or somewhere such things were legal, it would still likely make US TV. We don't let 8 yr olds make our T-shirts here, but we sure do wear the ones made in India without thinking twice.

     

     

    Also, you can teach your child that the universe was created by monsterous pasta, that foo ball is the work of the devil, and even to hate people with different skin.

     

     

    In a legal sense, I can't see any reason such a thing could not exist, because we outlaw acts, not intentions, and we allow people to do horrible things to the minds of their children due to twisted yet well intended lies and manipulation.

     

     

    In a moral sense, I'd say it should never be done, because I honestly don't think a person can gain a meaningful understanding of the world. How messed up would a person be if they spent years taking bad actors at face value? We need to be exposed to honesty and deciect to learn, often the hard way, if someone wants to harm or take advantage of us. Being deprived of that to me, would be as chilling as getting a labotomy.[/quote']

     

     

    That's all true; about it being feasible. But I still think a lawsuit over potientialchild abuse would win for the simple reason that the judge probably saw the Truman Show :P .

  5. The short answer to that is all of medicine is more of an art than a science. That is, there no three ring binder with a process written in it for producing a new therapeutic agent. There are sets of tools and there are empirical techniques that are used, plus a good bit of serendipity to discover a new drug.

     

     

    That's a good way of putting it. For all the memorization it takes to become a scientist, and to become a good one at that, blind luck and determination forged many of the discoveries we see today.

  6. Scientists can look to nature and see what are different animal behaviors and then determine if they have medical value. So, for example, there's a pain killer (Prialt) that uses a compund found in a cone-snail. The snail uses this venom to immobilize its victim before eating it. Scientists who wanted to find a natural pain-killing compund looked, logically, to animals like this rather than a deer or goat.

  7. Yeah it looks like your petri dish was contaminated by some type of mold. If you prepare another dish, try to make sure you wear gloves, don't put the dish plates on a table etc.

     

    That is a nice mold colony though, why don't you examine that while you have it?

  8. An American microbiologist, Sol Spiegelman, created the smallest possible replicating organism. He did this by taking a small virus, Qb, and giving it replicase so it could replicate. Then he added nucleotides and let it start to slowly mutate. Eventually it went from its original size, 4,500 base pairs, to 220. This little "monster" could replicate extremely fast due to its size and was the smallest organism while it was "alive."

     

    I, personally, doubt the validity of the story. 220 base pairs? That would only be enough for replicase. What about RNA polymerase or other vital proteins? In any case I think it's an interesting idea. But this all raises the question of what is the smallest organism (in theory). So then, what is the smallest theoretical organism, or does anyone think the Spiegelman account is true?

     

    (In case you want to read an account of the story: Spiegelman's Monster)

  9. You're right Phi, people's motivation would lay soley on finding batteries or getting electricity for their next "high".

     

    Also, what are the long term effects of a near-constant stream of electricity on the brain? I'd imagine that might corrupt the neuron impulses.

  10. Picking up from what Dak said, anti-virals do exist and are custom made for each virus. But they also might have to be made for each strain if they are unique enough. Even then, viral evolution is such that an anti-viral wouldn't be that effective for long. Viruses are very very messy when the transcribe their RNA and so a lot of mutation creep in, speeding up evolution.

  11. I'm all for personal freedom and orgasms for all --but this has some social problems. First off, this will quickly become the most addicting drug known to man. The brain likes sexual feelings, because that leads to more people and hence survival of the species, so it will program us to like this Button. So people will do anything they can to keep the euphoria going; and what happens when the batterys die? They'll do anything they can to get batteries and will fight for them with other addicts. It'll be a problem. Also, they're motivation will be zero and will be completely unproductive at work - if they show up at all.

  12. There have been many innovations in neuroscience lately, it seems as if the brain can't hold its secrets from us for long.

     

     

    From the first brain prosthesis:

     

    AN ARTIFICIAL hippocampus' date=' the world's first brain prosthesis, is about to be tested in California. Unlike devices like cochlear implants, which merely stimulate brain activity, this silicon chip implant will perform the same processes as the damaged part of the brain it is replacing.

     

    The prosthesis will first be tested on tissue from rats' brains, and then on live animals. If all goes well, it will then be tested as a way to help people who have suffered brain damage due to stroke, epilepsy or Alzheimer's disease.

     

    Any device that mimics the brain clearly raises ethical issues. The brain not only affects memory, but your mood, awareness and consciousness - parts of your fundamental identity, says ethicist Joel Anderson at Washington University in St Louis, Missouri. [/quote']

     

    To a man controlling a computer with his mind:

     

    A pill-sized brain chip has allowed a quadriplegic man to check e-mail and play computer games using his thoughts. The device can tap into a hundred neurons at a time' date=' and is the most sophisticated such implant tested in humans so far.

     

    Many paralysed people control computers with their eyes or tongue. But muscle function limits these techniques, and they require a lot of training. For over a decade researchers have been trying to find a way to tap directly into thoughts.

     

    In June 2004, surgeons implanted a device containing 100 electrodes into the motor cortex of a 24-year-old quadriplegic. The device, called the BrainGate, was developed by the company Cyberkinetics, based in Foxborough, Massachusetts. Each electrode taps into a neuron in the patient's brain.

     

    The BrainGate allowed the patient to control a computer or television using his mind, even when doing other things at the same time. Researchers report for example that he could control his television while talking and moving his head.

    [/quote']

     

    Neurology is taking a leap into the future, so what's next? More importantly, where do you see neuroscience in 50 years; what will be the major neurotechnological revolution? Brain chips? Cures for Parkinson's and Alzheimers'? Replacement parts? Or even the elusive answer to what makes us conscience.

  13. I highly doubt a corporation could adopt a child, who would be it's legal guardian? And if they were to actually do so (weird...imagine Enron changing diapers...) there are child abuse laws barring them from puttin the child at the center of a twisted reality show.

  14. This is more responding to the OP than what others have said. Like others have said, congratulations on overcoming your problem; it's very hard to break an addiction because it becomes ingrained in your brain. That's the big issue with trying to finesse the neurotransmitters; addiction worms its way into other parts of the brain. Biochemically, the problem is the "conflict" issue" Dopamine, the neurotransmitter involved with addiction, is involved in a few other neurologic pathways, like the Tuberoinfundibular pathway (controlling maturity and hormones) and the Nigrostriatal pathway (involved with motor functions). So, even if you were able to inhibit dopamine, a pretty formidable task, you would have the problem of severely hampering the other dopamine-focused pathways.

     

    The other aspect is that when your brain believes something is "beneficial" to your health it will send impulses to the memory section of the brain telling it to remember the chain of events that leads to that action. In the motor control area, a similar message is sent that allows it to preform what is remembered. So, it will be very hard to get rid of this ingrained response. It's near impossible to get rid of it medically so you would have to physically over-ride it by repeatedly not taking the drug and telling your body "See? I'm not taking this drug and I'm still healthy. So stfu and get rid of that response."
