Scientists Produce Fearless Mice 499

Dotnaught writes "According to New Scientist, a Rutgers University geneticist has found that turning off a specific gene for the protein stathmin makes mice fearless. The story speculates that this research might improve treatment for phobias. It does not mention obvious military applications for the discovery. As noted in this Naval Officer's guide for managing fatigue, the use of amphetamines to stay alert, followed by sedatives to sleep, has a long tradition. Genetic treatments may offer an alternative to pharmaceuticals."

    These mice escape and breed in the wild. Enormous of fearless mice terrorize the world's cat population. It's not going to be pretty.

      Three mice were sitting in a bar, each trying to impress the others with how tough they were.

      The first one said, "When I see a mousetrap, I deliberately set it off, bench press the bar fifty times, then snack on the cheese."

      The second one, not to be outdone, said, "Yeah? Well, every morning when I get out of bed, I stir in some cream and rat poison in my coffee. It gives me a good buzz that really wakes me up and gets me going."

      They both look at the third mouse who, after a few seconds, gets up and says, "I don't have time for this bullshit. I've got to go home and fuck the cat."

        Some Guinness was spilt on the bar-room floor
        Just around closing one night,
        And a wee little mousie crept out of his hole
        And into the pale moonlight.
        He lapped up all of that dark frothy brew
        And back on his haunches he sat,
        And all the night long you could hear that mouse roar,
        "Bring on that god-damned cat!"

        In fact this situation is possible and not funny at all.
        It was the night before Christmas and a creature was stirring. It was a mouse, a grey mouse, a lean and hungry grey mouse.
        A slight breeze shuffled discarded newspapers in the grimy alley as the mouse crept a little closer to its prey. The tip of its scaly tail twitched in anticipation as it tensed its muscles for the leap.

        With saliva dripping from its fangs, the mouse covered the intervening centimetres in a huge bound, jaws fastening viciously onto its prey, a high-pitched growl issuing from deep from within its belly. Snarling, the ferocious rodent tore at the flesh of its enemy, and the rottweiler leapt to its feet with a surprised yelp.

        The mouse, every muscle shaking with anger and bloodlust, bit deeper through the rottweiler's fur, amost drawing blood, until the startled dog nipped its head off and swallowed it.
        No, you're right, it isn't funny.

          They also have two cats. I tend to attribute all kinds of things to cats, and one of them is that they have a sense of what they're allowed to do and what not. I guess the cats figured that this bird was part of the household, and somebody would get very

When the cat came in the room, the bird would swoop down just above the cat's reach. Eventualy the cat grew tired of being teased and started to reduce the height of his jumps, in return the bird swooped lower untill the cat finaly nailed the bird and sent him sailing across the floor.

      Except, Krazy is deeply in love with Ignatz Mouse. Ignatz, meanwhile, finds his primary purpose in life is to throw bricks at Krazy's head. Krazy Kat interprets the hurling of said bricks as thoughtful tokens of Ignatz's affections. The dog loves Krazy, and so spends his time trying to put Ignatz in jail.

    Whatever happened to the good old days of pumping soldiers full of angel dust to rid them of fear?

    The non-military uses for such a treatment are pretty far-reaching. Would it be able to cure people that suffer anxiety attacks? Could children with night terrors be cured?

    If the rats don't feel fear, do they also lose understanding of danger? That would be a pretty bad mutation.

    Giving Methamphetamines to soldies to "stay alert" and to "strengthen confidence" has -sadly enough- a long tradition. As Wikipedia tells us [wikipedia.org] even the Nazis spreaded the drug among their Wehrmacht.

      What do you mean, "even the Nazis"? A totalitarian government, emphasizing the military and denial of the individual, would be almost expected to do this. What is more scary, is that democracies, which we expect to respect and defend the rights of the individual, even to the point of restricting what the police and military can do, are chemically altering the bodies and minds of their soldiers.

      • The purpose of amphetamines is to keep the "push" going; constantly moving forward against the enemy and keeping them off balance, unable to regroup. It's a way to win a battle and keep more of your soldiers alive. It's a standard strategy in all modern armies and would be used regardless of the availability of drugs, the drugs just help them stay awake and stay alive.

      Predators don't panic at every little oddity in their environment. They are much more inclined to explore new stuff than run from it, and to stop and think rather than run away screaming. They learn fear of bad things from experience, rather than just being generally afraid of everything. They can relax, because they learn that not everything in their environment is a threat.

      I don't think so. Fear is not the source of all human behavior. Without fear, people could still say, "Well... I could jump off the roof, but then I'd probably break a few bones, and that would hurt, and I don't like being hurt." (After all, you are arguing right now that there is something inherently bad about being shot in the head, surely a fearless person might be able to see your argument.)

      Fear is merely a mental shortcut. Instead of rationally arguing that doing something will lead to an unadvantageous situation, our brains merely automatically develop fears of the situation and we avoid it quasi-instinctually.

      That said, if you were to completely remove fear without changing anything else, I do not doubt that shit would happen. Human beings are nowhere near as smart as they could be, and are probably not capable of thinking things out clearly enough. As it stands, we probably need mental crutches like fear until we are able to augment our intelligence.

      But still, we should not imply that fear and desire are the only things capable of driving people. Fear is distinct from pain, desire is distinct from happiness.

    It does not mention obvious military applications for the discovery.

    That's because there is no military applications. You don't want the soldiers to become fearless, because if they do, they might say: "This war is wrong. I used to be too afraid to do anything about it, but now I suddenly feel fearless, and will get the heck away from here !" Basically, fearless soldiers will refuse to obey when given orders that they think are wrong, and cannot be forced to obey by fear of punishment.

    What you want is soldiers that are more afraid of their commanding officers than the enemy; that way they'll follow orders.

      What you want is soldiers that are more afraid of their commanding officers than the enemy; that way they'll follow orders.

      It is a bit of oversimplification. Soldiers can be motivated by things other than fear: the sense of friendship, pride, the feeling of responsibility and (misguided or not) patriotism. History is full with exapmles of people knowingly and willingly sacrificing their life for good of others, ranging from Spartans to Soviet atheists (neither of those could even hope for a decent afterlife: the void of Hades ain't much better than simple non-existance). I believe that in Iraq fights of today you could find such instances at both sides involved, too.

      That said, your general argument remains valid. Humans for high command are mostly numbers, and are operated from statistical point of view. They would hate to rely solely for underlings' loyalty.
    • Basically, fearless soldiers will refuse to obey when given orders that they think are wrong, and cannot be forced to obey by fear of punishment.

      My impression is that the vast majority of soldiers obey orders because they have been brainwashed into wanting to obey them.
