That's why my eyes lit up (not!) when I saw this headline in Biology New Net: New mechanism in gene regulation revealed. Here's the teaser ...
The information encoded in our genes is translated into proteins, which ultimately mediate biological functions in an organism. Messenger RNA (mRNA) plays an important role, as it is the molecular template used for translation. Scientists from the Helmholtz Zentrum Muenchen and the Technische Universität Muenchen, in collaboration with international colleagues, have now unraveled a molecular mechanism of mRNA recognition, which is essential for understanding differential gene regulation in male and female organisms. The results are published in the renowned scientific journal Nature.It took me a few minutes to track down the article because there weren't many hints in the press release. Turns out it still hasn't appeared in the print copy but it's available online.

Nature published online Sept. 7, 2014 [doi:10.1038/nature13693]The "new mechanism" is the binding of a protein to mRNA to block translation.
I suppose it depends on your definition of "new." We've been teaching undergraduates about this for over thirty years.
There's nothing in the paper about a new mechanism of gene regulation and there's no evidence in the press release that any of the authors make such a claim.
