The journal Regulatory Toxicology and Pharmacology has retracted their 2000 article that concluded Roundup poses no health risks to humans, citing “serious ethical concerns regarding the independence and accountability of the authors.”

Roundup owners Monsanto and Bayer have fielded almost 200,000 individual lawsuits over the last decade claiming that exposure to the herbicide caused cancer. But just last week, the U.S. Solicitor General filed an amicus brief with the Supreme Court urging them to protect Bayer from litigation.

Pete Hardin and Bert Zipperer share a news roundup on Roundup, in this edition of “The Milkweed.”
