Episode 529 - Listening in on conversations inside your body

Your body is constantly communicating about what's happening outside and inside of it, but how can we listen in. When your immune system is responding to a virus, or a wound is healing, there are lots of signals to decode if only we could hear them. By amplifying the signals inside your body with special folding DNA and transistors we can understand how our body responds. The brain's neural networks are a treasure trove of information if we're able to blend in and listen. Using a microbot you can get precise information from on inside in the brain rather than relying on external information. Xudong Ji, Xuanyi Lin, Jonathan Rivnay.
