    • I believe that they've already covered such places. In fact, they would probably argue the following:

      1.) These bacteria are more toxic than those found on Capitol Hill since the ones on Capitol Hill still have expensive and delicate outer coverings on themselves. The lack of corrosion of these outer coverings is something that would occur naturally with the newly discovered bacteria, thus, they are more toxic than those on Capitol Hill.

    The most extreme posters have been found to live in caustic environments such as "Slashdot". They thrive in flames, insults, gross-out posts, and even first posts. They are known in the scientific world as "posterus slashdotterus". They are a dangerous species and should be handled with care. If you meet on, please call your local police authority immediately.

      The slag dump in the story is not highly acidic, it's highly alkalinic. Acidic would be a ph lower than 7. Alkalinic is a ph higher than 7. The dump in the story was measured to be 12.8.

    Extremophile bacteria [unsw.edu.au] are found in all sorts of extreme places. Some can live in jet fuel (they corrode the tanks and require antibiotics in jet fuel). Others live in the acidic high-temperature hotsprings in Yellowstone. And entire ecosystems thrive around the 600 degree F "black smokers" in deep-sea thermal vents.

    • Environmentalists don't have such knee-jerk reactions to the destruction of ecosystems or species: they want to preserve ecosystems and species when it makes biological sense.

    I don't know much about these kinds of bugs but I used to live in an area that was close to an old copper mine. The community tried all kinds of things to deal with the slag, including planting sunflowers (a.k.a. Jerusalem Artichokes) in it. IANABiologist, does anyone know if these things could actually be used to clean up slag? The article didn't really go in depth.
    • Well seeing as the bugs live off of the current envornment by "cleaning it up" they would be exterminating themselves.
      The concept of planting sunflowers or other species of "normal" plants is that life attampts to maintain an environment where it will survive. Thus sunflowers would attempt to change the slag dump into a envornment where it can live and thus so can we. These bug, in there attempts for survival, whould maintain the alkaline nature of the dump and thus be counter productive.
      • Um, it doesn't really work like that. Small life forms will reproduce as fast as they possibly can for as long as the food source is viable. After that, the huge population starts to die off to a level that is more sustainable by the environment. This also means there is less "food" which, if the food was a contaminant, means it has been partially processed. However, no where do they "attempt to maintain their environment". That's just, well, silly. On top of that, are the bugs in question actually feeding
        • Yeah, you're right about the bugs eating themselves out of house and home. For those who've made beer, yeast is a good example of this, they generally eat all they can until their waste product (alcohol, a.k.a the good stuff) is so strong they can't survive.

          The article mentioned the bugs feeding on the free hydrogen from the slag. It wasn't clear if that was the contaminant or just something else present in the slag.

    • It's called phytoremediation.

      The plants function as a contaminant sink - they are capable of absorbing trace amounts of elements/minerals from the soil. If you harvest the biomass, then you collect some of the pollutants along with it.

    Living in extreme environments is one thing, but completely different respiration systems is another thing entirely. This article reminds me of one I saw here [chemslash.com]. Apparently, some microbes discovered utilize iron as opposed to oxygen in order to sustain themselves. That's quite an accomplishment.

    There is no evidence that these bacteria evolved at all. This is just another case of scientific zealots bending the facts to fit their evolution-dogma. The scientific preisthood refuse to publish any paper that openly discusses the merits of creationist theory.

      Most likely the slag-dumpage occured over time as a result of industrial or mining processes. As the pH level is gradually increased, microbes that are not alkaline resistant are killed off. Those that are alkaline resistant, manage to live.
