Scientists Produce Fearless Mice

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."

      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.

      I've seen cats being bullied by a bird. At my folks' place, they had this bird fly in one day, some yellow tropical one. Because the bird wouldn't go away, and nobody responded to the ad they put up, they decided to keep it, so they got a cage and all that.

      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 pissed if they harmed the bird in any way. Or maybe they just found the bird so scary that they didn't dare to lift a paw to it.

      At any rate, we all figured that it would be good for the bird to get some exercise, so we would usually let it out of the case (somehow the bird had the decency not to shit all over the house, or try to eat everything it came across). One day, one of the cats was sleeping somewhere on the floor, and I was watching (to intervene should murder be attempted) as the bird approached the sleeping cat and pick at it with its beak. The cat stirred a bit, but otherwise paid no attention. Then the bird picked again, and again, until the cat eventually woke up, looked at the bird (who leaped back a few paces), and then decided to try sleeping again. Since that time, the bird has been positively annoying the cats, to the point that the cats wouldn't want to sleep in the room where the bird was.

      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.

      Conversely, prey animals can't cope with change or oddness, and tend to flee in a panic and hide in the shadows even when the "threat" is imaginary. They have difficulty learning what *really* is or isn't a threat, because they're unable to stop and examine the situation; indeed, they tend to react more strongly on repeat exposure to a fear stimulus, because now it's a fear-trigger point rather than becoming familiar. They can't relax, because omighod the bogeyman might get us at any moment. Generally not a fun existence.

      Occurs to me that panic disorder in humans is fundamentally prey-animal behaviour. Inherited panic disorder also commonly occurs in other carnivorous and omnivorous species (cats and dogs). "Abnormal" boldness in prey species is much more rare, tho has been to some degree selected for in domestic livestock, to make them steady enough for humans to deal with.

    "Genetic treatments may offer an alternative to pharmaceuticals." So a company has two options. Either a (theoretically and best case) one time genetic therapy which will raise the wrath of a public who leaned everything they know about science from bad movies. Or slightly less effective pills targeting the same mechanism, but which can be sold again and again to a person throughout their lives. I think the whole customer for life deal has a bit more appeal.

    Some Guinness was spilt on the bar-room floor

    He lapped up all of that dark frothy brew

    But whether you're blocking the receptor with a chemical antagonist or a biological, it's still "pharmaceutical". The submitter's notion that gene therapy is an attractive "alternative to pharmaceuticals" is simply insane.

    Incidentally, there are lab mouse strains that don't have many of the anxiety behaviors like center avoidance. The article gives the impression that the knockout animals are utterly unmouselike, which is untrue.

  38. I'm not so sure by hey! · · Score: 2, Insightful

    We're a big bag of complex chemical equillibria and messy neural wiring. We give names like "love" and "fear" to aspects of the subjective experience of existing this way, but they're seldom precise enough to be something you can switch on and off. You're bound to get either more than you intend or less than you intend, or both.

    Fear would seem to be a good candidate for a neurobiologically switchable emotion, but even fear is more complex than it seems at first glance.

    I saw a photo in some book I read on the psychology of emotions that showed a truck tipping over. The truck was loaded with maybe thirty soccer fans returning from a game, and all that rowdy weight caused the thing to overbalance. The photo was taken just as the truck was approaching 45 degrees, and the people on the top were leaping to safety. What was interesting about the photo was the peoples' faces. The people leaping to safety had no look of fear or emotion at all -- just intense concentration. The driver, however is obviously terrified.

    The point is that there is arousal in response to danger, and there is fear. Arousal in the presence of danger is not fear: fear is specifically an emotional reaction to helplessness in the presence of danger. It's evolution's way of say, "If you're going to do nothing about this situation, then you'd better do it really, really unobtrusively."

    There is already a method for controlling and eliminating fear in a soldier. It's called "training". You ingrain the right response in a danger situation into him so he can act automatically. He may be afraid before hand and traumatized afterward, but you want him aroused and as close to fearless as possible at the moment of truth.

    Because of the imprecision of language, I suspect a pill that turns off "fear" would actually make a soldier's training less effective. The physiological and emotional response to danger which is not fear, or at least not exactly fear, curiously doesn't have a distinct name. Clearly this unnamed state is a kind of emotional state -- one in which reactions are automatic and information is extensively filtered down to that which is paradigmatically most useful for survival. Perhaps "fear" is a reasonable umbrella term for all kinds of arousal reactions to danger, but we have to distinguish between being "frightened" or "scared" on one hand and being "terrified" or "petrified".

    But whatever the word is, I expect the condition of reacting to danger is on the whole more beneficial to the warrior than it is detrimental to a warrior. And, as you say, if the soldier does not react in an emotional way to danger, then the way he does react is probably unpredictable. An ideal pill from a military standpoint would narrowly block the "petrification" reflex, without altering any of the other subjective aspects of fear.

    ... and for that extra helping of protein hunt for insects and in the case of rats even small birds and other mice. Both rats and mice also eat unhatched eggs. They don't have fangs like dogs and cats, but anybody ever bitten by a rat will tell you they have razor sharp incisors and a powerful jaw and the bite hurts plenty.

    However... to set the record straight, like most other mammals a rat will
    only attack a human when cornered or provoked. I suggest you do not pickup
    or otherwise try to pet the rat you find out in the streets but they are
    actually some of the cutest mammals in existance and they
    make excellent pets.

    Not necessarily. Darwinian evolution doesn't necessarily dictate that the best mutation wins out. It generally suggests that the mutation best adapted to the species' circumstances will survive, but really, anything that works well enough to allow further breeding will still continue to exist. That's why we have all sorts of absurd animals in nature right alongside the magnificent ones, and why in our own species various forms of genetic disease and handicap continue (although for the latter, our own social evolution and co-dependency has something to do with it too).
