The entire glyphosate (Roundup herbicide) saga is an appalling example of politicized science and motivated reasoning. Now key anti-Roundup papers AND key pro-Roundup papers have been retracted. Worse, I'd be willing to take odds that partisans of both sides will be completely unbothered by this.

pretty interesting to see a retraction after 2+ decades and 1000+ citations. Journal pulled it b/c of ethical concerns (undisclosed contributions from the manufacturer), apparently not b/c of new data or research - though they do cite relevant unpublished studies that were available but not included
Boy, retraction is the thing these days. After years of critique, a foundational 25-year old paper on the safety of glyphosate herbicide has been pulled. www.sciencedirect.com/science/arti... 1/2
