The US Supreme Court held oral arguments on April 27, 2026, in the Durnell v. Bayer glyphosate weedkiller case, part of thousands of lawsuits alleging cancer risks from Roundup. Justices appeared divided on federal preemption of state warning claims. This follows Bayer's February 2026 multi-billion-dollar settlement for many similar cases.
The journal Regulatory Toxicology and Pharmacology has retracted a 2000 paper claiming glyphosate is safe for humans, citing undisclosed Monsanto involvement and reliance on unpublished studies. This development highlights ongoing concerns about the herbicide's regulation in the US. Meanwhile, stingless bees in Peru's Amazon have gained legal rights in two regions for the first time.
