Remember that global increase in jellyfish populations? Apparently, the impacts of that are not limited to the field of ecology. In Scotland, an excess of jellyfish forced a nuclear power plant to temporarily shut down. There were so many jellyfish that operators were afraid the creatures would obstruct the flow of seawater used for cooling the reactors. (For clarification: The plant isn’t in trouble. It just went into a safe, controlled shutdown as a precautionary measure.) (Via TweetScience)
