Ants Turned Into 'Supersoldiers'

New submitter jmcdougald.esq sends word that a team of researchers from McGill University has tinkered with the development of a type of ant to produce what they call a 'supersoldier' subcaste — ants that are much larger than average workers but only appear naturally in a few species (abstract). The team's work showed that by exposing the ant larvae to a hormone-like chemical, they could induce 'supersoldier' growth in many more species. "This result suggests that supersoldiers existed in the common ancestor of the entire genus. Even though the supersoldier subcaste eventually disappeared in most species, the ants kept the potential to make it. Because the same hormone sets the fate of both supersoldiers and soldiers, it may not have been possible to completely lose one without compromising the other. ... In some species that evolved later, such as Pheidole obtusospinosa, the supersoldiers became a permanent addition. Whereas most Pheidole species simply evacuate their nests when army ants invade, for some reason P. obtusospinosa find it beneficial to stay, which makes supersoldiers a useful addition to the community."

    Ants rule. This is the coolest article Slashdot has published all week. Just look at these things. They're oversized, phallic monsters of doom with giant fuck-off heads. Unfortunately, it's hard to find out more about this ancient caste of ant because all the Google results right now are about this story, and there's no "History of ants" article on Wikipedia. But check out Martialis heureka, a newly discovered species in the Amazon that may represent the oldest living lineage of ants today.

      I agree, this is very cool. I do worry about these induced supersoldiers getting free, but I think the risk is minimal of that. Perhaps nonexistent if the ants themselves don't know how to unlock the special caste anymore, which would seem to be the case.

      But the thing is, it's not really a mutation. The genes are there, they're just being switched on, artificially, at a specific stage in development. These supersoldiers don't reproduce. If they did get out of the lab, they'd live their normal livespan and die, and there'd be no more supersoldiers.

      I'm guessing he means Africanized ("Killer") honeybees. Though in that case, some schmuck let 26 queens loose, so it wasn't the drones or workers doing the mating...

      Well, the article states that super soldiers are disappearing among a lot of ant species. Probably because they no longer increase the chance of survival. So if these do get out, they would most likely not survive very long. Apart from that, unless they release a supersoldier making queen, they won't be able to reproduce anyway. (cue Jurassic park theme song).

    Do you realize that cancer is actually caused by the rogue and uncontrolled triggering of cellular growth that normally results in healing?

    The fetus still goes through stages of growth that trace back to our evolution, a nine-month fast replay of evolution as the zygote develops into a viable organism.

    The concept of genetic engineering is not scary because of the "risk" of GMO fields infecting natural genetics, but because of the few psychopaths who would like to use such technology to "eliminate disease." Who's to say a "disease" is not the first step of the next stage of evolution? The brilliance of many people I've met with ADHD and various levels of autism disorders are a key example -- they're not SUCCESSFUL adaptations yet, but I believe they're the beginnings of an evolution of a greater intelligence than the typical modern human.

    Yep. Don't let them out. The Argentine Ant is a big enough problem already and they're tiny little inoccuous ants, but can have over 100,000 per colony.

    the ubercast Nietzsche is talking about is not the one the Nazi understood...

    From Beyond good and evil:

    What we nowadays call a “nation” in Europe is essentially more a res facta [something made] than a res nata [something born] (indeed sometimes it looks confusingly like a res ficta et picta [something made up and unreal]—), in any case something developing, young, easily adjusted, not yet a race, to say nothing of aere perennius [more enduring than bronze], as is the Jewish type. But these “nations” should be very wary of every hot-headed competition and enmity! That the Jews, if they wanted to—or if people were to force them, as the anti-Semites seem to want to do—could even now become predominant, in fact, quite literally gain mastery over Europe, is certain; that they are not working and planning for that is equally certain. Meanwhile by contrast they desire and wish––even with a certain insistence—to be absorbed into and assimilated by Europe. They thirst to be finally established somewhere or other, allowed, respected, and to bring to an end their nomadic life, to the “Wandering Jew.” And people should pay full attention to this tendency and impulse (which in itself perhaps even expresses a moderating of Jewish instincts) and accommodate it. And for this, it might perhaps be useful and reasonable to expel the anti-Semitic ranters out of the country.
