When it comes to experiments, it should be verified at least by
another group particularly for important results.
Another step, is peer review in which different people review the
paper involved.
The final step, is vigorous proof and vigorous testing.
Unfortunately, sometimes it is hard to catch everything, and this
was shown with regard to the S.Korean Professor who fabricated data
etc.
It doesn't help when some publications, particularly those that
cater to the layman, sensationalise results when they haven't
undergone vigorous review or anything.
