<p>Hi All,</p>

<p>I am wondering if anyone has found a good example of a scientific journal article that was badly reported in the media? I'd like to find a journal article and text from the media where the findings of the article are incorrectly conveyed. This is one of the outcomes of the HSC course and I have not found any excellent examples that fall within a core topic. I found one in astrophysics but it wasn't the best example.</p>

<p>Cheers,<br />
Jeff</p>
