At its worst we called say this was fake news. But this is exactly the kind of example I like to use when teaching students about the difficulties of striving for readability and accuracy as well as the wonderful complication of language especially when it comes to science. So when is a giant octopus not a giant octopus? Read on to find out. Continue reading
