On this week’s Tech Nation, We can track almost anything with a smart device - but is that data really private? Moira speaks with George Washington University Law Professor Andrew Ferguson about his book, “Your Data Will Be Used Against You: Policing in the Age of Self-Surveillance,” which takes a closer look at privacy in the world of smart devices. Then, Dr. Arun Swaminathan discusses how Coya Therapeutics is testing a new treatment for ALS. The goal? To stop progression of the disease in its tracks.
