Bringing people together to improve communication of research findings
I think a person without much scientitific background can practice science journalism better than others. The first main reason is that the person will not use any jargon while presenting information, secondly the person would have interviewed and researched the topic well, thirdly it will be well presented because it has been understood well by the presenter.
This goes without saying that most of the scientitific papers are complicated and not easy to understand. I have addressed this in one of my queries which you may like to see.
