I spent much of the day working on an article about what students can learn from the Seralini GMO-fed rat study. Beyond science, this controversial paper says a lot about the interactions between scientists, journals and the media. Here's an informative article from "The Conversation" that looks at the newsmedia aspect of the controversy : https://theconversation.edu.au/modifying-the-message-how-tricks-masked-home-truths-about-anti-gm-science-9767.
You don't have to look far for more examples of poor, erroneous or just mistaken science being heavily promoted to the public through a sometimes over-eager press.... think about XMRV and chronic fatigue syndrome for example, or the "arsenic life" story.
I particularly liked this post from WIRED in which Brian Switek talks about how the media blundered in covering a press release on a new theory about how pterosaurs lift off. He concludes by pointing out the deficiencies in the current system through which press release ---> news story, and how science is damaged by inadequacies in much of science journalism. Because much of what the public understands about science is filtered through the media, these organizations and individuals hold a lot of power, and you know what Stan Lee said about that....
