Publication in Nature is not so much for newest information on your specific and somewhat narrow subject, but for more or less breakthroughs of various degrees.

From guidelines[1]:

- report original scientific research (the main results and conclusions must not have been published or submitted elsewhere)

- are of outstanding scientific importance

- reach a conclusion of interest to an interdisciplinary readership.
