Ants Turned Into 'Supersoldiers' 80

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. [imgur.com] 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 [sciencedaily.com], 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.

      • It would be a travesty if some of the super soldiers escaped and bred a race of super ants... jk

        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).

      I think widespread genetic tinkering with the human genome will have several pressures involved. There's the parents who say "I want my baby to be normal" and the parents who say "I want my baby to be special."

      In the first category, you'll have pressure to eliminate stuff like autism or ADHD as you mention, but the second category is perhaps enough to balance that out. Those parents who might induce autistic-like conditions to make their child smarter in certain ways, or entirely new conditions that don't o

    • You have a point. However, if the disease is crippling and ends up resulting in nonviable offspring like Cystic fibrosis then I see no harm in parents who have the risk of having a child with it going and doing IVF and only choosing the offspring that don't have it for conception. Some genetic diseases like Cycle Cell have advantages, but it would be bad to assume that all genetic diseases can result in a benefit.

        Now there's thorny topic for anyone who has a fundamental disagreement with abortion. To them, killing a fetus is immoral no matter what the reasoning. And as the uncle of a boy who is autistic, I must admit I would hate to have seen my sister have him killed when he failed the genetic screening.

        I don't believe in abortion as birth control at all. It needs to be available to deal with cases of rape and occasionally to save the mother's life, but that's where I draw the line. There are far better way

          I don't really disagree with the spirit of your post there, but dumping it all on free condoms as the solution to every reproductive mishap is pretty naive. Ever had a condom break, even though it was fresh, and you stored and used it correctly? I have. The result of that unplanned event is 18 years old now.

        The big problem with your reasoning is, no doctor can guarantee that your child will be healthy and disease-free. And sometimes, you even get some false positives.

      This is not quite right; Haekel's Recapitulation theory has been rather thoroughly refuted.

      The link between savantism and autism is fairly well established, as is the link between artistic genius and schizophrenia and/or bipolar disorder. The fact that persons with atypical neurology of this type occasionally exhibit extraordinary inventiveness, creativity or insight in some areas may well account for a non-trivial portion of human cultural and technological evolution.

      The cool thing here is that, according to the article at least, they aren't actually modifying genes anywhere, just introducing a hormone to activate genes on a one-off basis. Take away the hormone and everything is back to normal.

      The next step, correcting the evolved corruption in the DNA that prevents the hive from releasing the hormone, wouldn't be too hard though.

      Who cares? Natural mutations are random and undirected. Pressure from the environment directs evolution, but that makes organisms better suited to survive in their environment, not necessarily better by all measures. For example, bats evolved their sonar system, but took a step back and lost their vision.

      We're evolved high intelligence now. We can do a better job than nature in directing our own evolution. No need to ever take a step back, just decide where we want to go and work towards that goal.

      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.

    • The ants weren't acting as a global hive, per se. They were just genetically related and so didn't attack each other in experiments, and so technically counted as members of the same colony.

  • If an ant army invades another ant colony they have huge soldiers to protect it, its not really an invasion. Its high protein free room service.
