More than anything else what I was trying to say in my ramblings was that Im
always a bit sceptical when people publish their research in a magazine rather
than
a journal. It simply makes me wonder if the research wasnt good enough or the
conclusions made too far fetched for it to be accepted.

All the other bull I mentioned were simply potential explanations that you'd
normally
have to rule out before you can publish. And I was simply wondering if they
actually
had done that.

It takes a lot of effort to design an experiment (more work than the actual lab
work) so
that you make sure your results/measurements actually let you answer the questions
you
were trying to answer.

It reminds me of a story in one of Richard Feynmanns boooks. Back in the 50s and
60s
a lot of research was done into brainfunctions and learning abilities. One of the
favorite
experiments was to run mice through a maze and test their ability to 'memorize'
how to
find the cheese. Lots of experiments were made and one team actually did a study
on how to
construct a maze in such a way that the mice had no other ways to tell (e.g. by
the sound of
their feet on the wood or lighting etc) how to get there, i.e. they were forced to
actually be
able to memorize the path. So basically this paper established the foundation of
how to conduct the experiments and have reliable results. However very few if any
papers
published later referenced this, so you can only guess at the quality of their
results and conclusions.

In this particular case (of the fish), even if the basic work was done correctly
the interpretation of
the results may still be controversial. If the measured amounts are higher in
farmed salmon
but still far below what the general scientific community regards as the upper
level for
whats acceptable for human consumption the group may interpret it in a way which
is at odds with
their research peers i.e. not everyone agreeing what the safe level is (my fist
email). Thus your paper may not be accepted in the scientific community, but you
can probably find some journalist who is willing
to bring it simply because of the stir it will cause.
