Frankly, I think science journalism has exactly the same responsibility as regular journalism. "Report verbatim" is not, to me, the right answer in any way. That's press release journalism, which is irresponsible. A media outlet which is going to report on science ought to have at least one person working there who either understands it or can find someone to explain it in a way which will let them explain it so the average consumer of that media outlet will understand it. Necessary warnings should be stated when findings aren't conclusive, but I have to tell you, there's a limit to how much I think things based on a single study should be reported in the mainstream media at all.
