Plants Near Chernobyl Adapt To Contaminated Soil 293

lbalbalba writes "In April 1986, a nuclear reactor at the Chernobyl power plant in Ukraine exploded and sent radioactive particles flying through the air, infiltrating the surrounding soil. Despite the colossal disaster, some plants in the area seem to have adapted well, flourishing in the contaminated soil."

      Depends on the type and strength of radiation present. If it's mostly alpha particles then it will be blocked by your skin, but they can still penetrate mucous membranes (like in the nose and around the eyes) or be inhaled and absorbed through the lungs.

      There is also the inverse square law, standing several feet away from a lightly radioactive source is going to be less hazardous than handling it with your bare hands. Hence the gloves.

      Under the right circumstances, evolution can be quite fast. The geological history of the earth shows many massive die-offs followed by a tremendous flowering of new life forms. If there is an ecological niche available, something will adapt/evolve to fill it.

      Naturally, simpler life forms evolve faster than complex ones. Germs evolve in months. Humans evolve in tens of millennia. Plants are somewhere between the two.

      Not to mention a nifty "myth busted" moment for that old Hollywood trope of a post-nuclear wasteland.

      The explosion at Chernobyl wasn't a nuclear one, it was steam (due to a massive reactor power spike thanks to the skillful removal of pretty much all possible safety procedures in an already sub-optimal reactor design) that blew open the core and scattered radioactive material over the landscape and into the atmosphere thanks to the lack of a containment vessel. The Hollywood trope of the post-nuclear landscape typically involves the detonation of several hundred megatons of nuclear bombs and, as near as we can tell, is pretty accurate; Chernobyl isn't really comparable to a nuke in either the degree of the explosion or in the amount of radioactive fallout. /nitpick

      My understanding was that the point of this article was that this was not evolution, or at most an evolutionary switch-on of a feature that evolved long ago.

      When plants reach for the light, it's not because they are evolving into a new organism on the spot. Rather, they have long ago evolved to dynamically adapt to lighting conditions. What TFA is proposing is that plants dynamically adapt to ionizing radiation as well, and they have had that capability for some time, it's just that we haven't been in a position to observe it.

      As to the rest of your comment: If you think "environmentalists are always predicting some kind of terrible apocalypse withing the next couple of decades" and cite "global cooling" as an example - maybe you're not an AGW denialist, but you have apparently picked up some of their rhetoric style.

      This is how the BBC reports online - single sentence 'paragraphs' under headings that are closer to where you'd really divide paragraphs. I'm not sure why you're so outraged, news reports in general use short paragraphs and fragments. The NY Times, for example, frequently uses single sentence paragraphs.

      It makes articles easier to skim and ensures a consistent style between journalists, I'm not sure what your issue with it is.

        It's not just the single sentence paragraphs, but also the near total lack of flow to the text. It reads like bullet points scraped off a powerpoint. I hadn't noticed how short the NYTimes paragraphs were, mostly because there's still some craft to the prose. The NYT still reads like it was meant to be read by literate humans, not parsed by a computer.

    Troll Alert : It boggles my mind why people still don't accept evolution as being a close approximation of the truth. I say "close approximation" because even physics is an abstract collection of ideas meant to help our human minds approximate physical laws of our Universe. As a species have had numerous examples of evidence be observed or deduced which support evolution. There is observed evidence, as in this case of plants near Chernobyl as well as others like the peppered moth, and qualitative evidence paired with analysis such as in the case of the varied forms of archaeology. These plants represent a micro-evolutionary step, as some people refer to it. Macroevolution(tau) = Microevolution(100000*t) . Differentiation within a species given enough time diverges the species into parts. Simply put, give it enough time and micro-evolution becomes macro-evolution. If you have some math background you will also deduce my other point; no matter what you call it its evolution.

      Read their method.

      They first observe that plants start to spontaneously grow again in contamination sites despite the high radioactivity. Then they brought in seeds from uncontaminated origin. One batch goes to the contamination site, and another batch (the controlled group) goes to a decontaminated area near the site. Seeds grow fine in both batches, showing that seeds from uncontaminated origin is able to survive the radioactivity in the very first generation. The study is about the mechanism how plants naturally resist radioactivity. No evolution is taking place here.

Put those same catfish in areas where the rednecks would be afraid to eat them or even use the waterways for transport and guess what you'd find? These things would thrive in the right conditions.

      Oh please. I am a radiation expert in real life. I have been to Chernobyl. It is no more "eerily silent" there than it is in the non-contaminated areas. The surrounding area is mostly farmland and was cleared many years ago. Perhaps the simplest explanation is that the plants and animals are just not as sensitive to radiation as the movies and sci fi shows suggest. That plus the fact that most of the isotopes released (iodine-131 for example) have long decayed away. Humans are more sensitive to the effects of radiation than most other creatures. When we protect humans we end up protecting the environment. That said, even though I full expect the plants to grow healthy in the downwind zone, I would not eat them for fear of further concentrating any remaining contamination they contain and raising my risk of cancer. But I don't smoke, either, for similar reasons.
