The current retraction wave in Nature is still highly discussed in the scientific community. Indeed, as of September 2014, the number of retractions is 8, which is yet even higher than in 2013, where it have been „only“ six retractions. In this discussion, the record from 2003 is often referred to, which is supposed to be 10.
So, what is going on in Nature? Paul Knoepfler addresses this question intensively in his blog, also pointing out that the increased number of retraction might be the result of a lower tolerance by the staff of Nature. Although the numbers of retractions over the last years look impressive (1–2–6–8, ranging from 2011 to 2014), this high number of retractions looks different in comparison to the record in 2003. Nevertheless, I have to contradict @Richvn, as two of the ten listed papers are related to retractions, but are not actual retractions.
The contribution from my side to the ongoing discussion about Nature‘s wave of retractions is therefore, that this at least is not unique in the history of Nature. Nevertheless, 2014 has not passed yet. And several publications are, of course, retracted at a later point of time.
