Cottage Grove, Minnesota, has had a 3M factory in town since 1947. It makes everything from Post-It Notes and Scotch Tape to reflective road signs. In 2017, the city found out the state was lowering the acceptable level of PFAS, a chemical made and used at the factory, in its drinking water. Scientific studies show there could be serious health consequences for people exposed to it. And now dozens of U.S. cities are discovering PFAS is in their water too. This week on Decrypted, Bloomberg's Tiffany Kary and Pia Gadkari tell the story of how a Minnesota lawyer first learned of PFAS contamination, and discuss documents revealed through lawsuits that suggest 3M knew of certain risks for decades and never disclosed them. 3M says those documents have been taken out of context and that the chemical isn't a danger to public health.

As medical technologies get cheaper and more accessible, patients and DIY tinkerers are trying something similar—and mainstream medicine is racing to catch up. Prognosis explores the leading edge of medical advances, and asks who gets—or should get—access to them. We look at how innovation happens, when it fails, and what it means to the people with a disease trying to feel better, live longer, or avoid death.

In 1987, a young couple was killed in Washington state. This case, and others like it, were unsolved for decades — until a new technology emerged. This week on Decrypted, Bloomberg's Kristen V. Brown visits CeCe Moore, who's at the forefront of using genetic genealogy to hunt killers. Her work is made possible by consumers who upload their DNA test results to the internet to learn about their family lineages and their own health.

The e-cigarette maker Juul has seen stratospheric sales since early 2017, making it one of the buzziest startups in Silicon Valley. But now a backlash over the company's popularity with teenagers could jeopardize that. This week on Decrypted, Olivia Zaleski and Pia Gadkari trace the company's story from its origins. Juul says it only ever wanted to help adults quit smoking. Instead, it's become a social media sensation. And critics fear teen vaping is nothing short of a new public health crisis in the making.
