Mice Brainpower Boosted With Alteration of a Single Gene 105

Zothecula writes: By altering a single gene to inhibit the activity of an enzyme called phosphodiesterase (PDE4B), researchers have given mice the opportunity to see what an increase in intelligence is like. "They tended to learn faster, remember events longer and solve complex exercises better than ordinary mice. For example, the “brainy mice” showed a better ability than ordinary mice to recognize another mouse that they had been introduced to the day before (abstract). They were also quicker at learning the location of a hidden escape platform in a test called the Morris water maze. However, the PDE4B-inhibited mice also showed less recall of a fearful event after several days than ordinary mice." While many people would welcome such a treatment, the scientists say their research could lead to new treatments for those with cognitive disorders and age-related cognitive decline.

    I would laugh so hard if they develop a drug based on this and the only skills that people gain are the ability to recognize mice better and to be less scared of open spaces and cats. Oh and to find hidden escape ways.

    But really I do look forward to what will happen someday if these cognitive enhancement drugs turn out to be safe and make people smarter. I am not talking a limitless sort of thing but what happens if a university course ends up be retuned to be just too difficult for most people unless they are taking these sorts of things? If that hasn't already happened with things like Modafinil.

    • Usually, the bottleneck associated with bigger brain isn't lifespan, but energy expenditure.

      Bigger brain eat up more energy and that must be balanced regarding cost/benefit.
      - How much more food would an animal X find with the bigger brain vs. how much more food would the animal need to eat to sustain this brain ?

      "bigger brain" mutation don't happen that much in the wild, and usually are being done by labs partly for this reason:
      because lab mice are guaranteed to receive suffisient food and not starve.

    To be competitive, I'm pretty sure certain nations would allow and/or require adjusting human brain genetics to breed a "super race" with superior intelligence, memory, and/or discipline.

    I don't know how long a nation that forbids such could compete. If the super-brain nations become a threat, the hold-outs will be forced to tinker also.

    • You're right. Somebody is going to try this. And a lot of people will loudly object.

      But depending on how it turns out, everybody else will also.

      And the result will be a caste society, with the fearless, superintelligent transhumans ruling the masses of those with random genotypes.

      Our only hope is that, if performed on humans, it produces some crippling side effect, like the inability to use language.

    However, the PDE4B-inhibited mice also showed less recall of a fearful event after several days than ordinary mice.

    Perhaps being smarter enabled them to process the "fearful event", determine the cause of the fear, the amount of actual hazard and any risk mitigation actions they could take, and thus not be as "afeard" the next time that event happened?

    That's what humans do. They get scared by something, realize that the fright was temporary and not based on an actual threat, and desensitize.

    And my fist thought was "Flowers For Algernon", too.

      'Stupid' is not just a matter of low intelligence. It's also a subject of cognitive biases and undisciplined thinking.

      For a good example, look at Ben Carson, one of the Republican candidates. He has spouted a steam of policy positions that most people would regard as stupid: He suggested abolishing all taxes in favor of a fixed 10% income 'tithe' because that is what the bible specifies, he said that homosexuality must be a choice because people turn gay in prison, and he has claimed that the affordable care act enslaves people to the government. But is he stupid? Certainly not: Before going into politics he was a neurosurgeon, and a very good one too, one actively involved in research and responsible for developing new procedures. He is literally a brain surgeon.

      What Carson shows is that it's quite possible for a person to be of brilliant intelligence, but still come to hold positions that are quite obviously ridiculous. Humans are not logical creatures by nature: Their minds are the product of a process that optimized for reproductive success. A cobbled-together tangle of heuristics.

        The idea that homosexuality has one and only one cause (either biology or choice) is silly. Most complex human behaviors have many inputs, and sexuality is very complex. The desire to reduce human sexuality to choice or biology is a desire to make a moral issue out of it or remove it from moral consideration, but not a desire to explain what is going on inside a person. If you believe that no one is predisposed to homosexuality but rather homosexuals all consciously choose to engage in homosexual acts, or i

          The idea that it is a choice is just plain silly. I noticed about the time I hit puberty tht I found a certain reaction to long legged women, tall with a nice backside, and with long hair, and not large breasts. I never woke up one day and said "Hey - I think I'll go for tall, leggy women with nice asses, long legs, lonf hair and small tits." I kinda noticed because of reactions my own personal body had when seeing one. And not the obvious one, but just a heightened interest, and a greater enjoyment in lo

          A friend once told me of a conversation he had with his dad:

          Dad: "When did you decide you were going to be gay?"
          Him: "When did you decide you were going to be straight?" ...

          If you were expecting more after that build-up, I'm happy to disappoint. I think the point is made.

      • Just because someone starts with different axioms doesn't mean they're not logical.
        • by Mr.CRC ( 2330444 )
          It's not clear that people start with any consistent set of axioms at all. And inherent logical contradictions run rampant. The brain is not logical. It's inductive. It's designed to come to a decision, any decision, which is usually better than a detailed and disciplined logical analysis when it comes to avoiding becoming a meal.
      • One could also argue that while those positions are utterly stupid, if enough people will vote for you based on your espousal of those positions than it's also highly intelligent to pay them lip service. Given that we're in the realm of politics, one could also make all manner of other arguments that normally shouldn't be plausible or worthy of much thought, but are within the realm of probability.

        It also goes without saying that most every individual is likely to hold some position or behave in some man

      Genomes are usually well balanced and it is difficult to globally "improve" healthy people with a single mutation without causing nasty side effects. If altering a single gene is the solution, evolution would likely have done it already. Illnesses are different : they are usually caused by an undesirable mutation at some point and the idea is just to revert the damage. Engineering resistance to a specific toxin or disease (like GMO crops) is also a different matter : this is a specific improvement, and it o

      • A better known and safer alternative is resveratrol. You can try taking supplements which may or may not work, or just drink the red wine.

        Resveratrol is an exceptional PDE-4 inhibitor. One supplement that has been thoroughly tested and found effective is Longevinex.

        The best alternative that I have found is the wonder drug called fuckitol. It is a stress reduction serum that dramatically lowers the levels of cortisol in your body.
