Sampling error, flawed analysis, and miscalculation trigger Molecular Cell retraction

Guest post by Jean Hazel Mendoza A group of researchers from France has retracted a 2013 paper from Molecular Cell after realizing that their analyses of microscopy images were flawed.

The author of a controversial 2009 paper arguing that at least some amount of global warming could lead to economic gains has corrected the paper, along with a later article in a different journal. We confess to be baffled by the implications of the mix-up, although others appear to be less confused. The 2009 article, … Continue reading “Gremlins” caused errors in climate change paper showing gains from global warming

Miłość at first sight: A retraction notice worth emulating from Poland
