German chemical company Bayer has agreed to let an independent scientific team study the health effects of its popular weed killer, Roundup. Legal experts say the company hopes results of the study will prevent future lawsuits by people who claim the product is harmful. Bayer agreed Wednesday to pay as much as $10.9 billion to end legal cases brought by U.S. Roundup users who say the product gave them a form of blood cancer. But as part of the settlement agreement, Bayer had to find a separate solution aimed at limiting future claims without removing the product from stores. The company decided to take a risk that the scientific study will support its claim that the chemical glyphosate is safe for agricultural use. Glyphosate is the active ingredient in Roundup.
