At some point or another, we all experience physical pain. We push through it or turn to medicine, from aspirin to opioids. New research published in the journal Science highlights a more mechanical alternative: a biodegradable implant that cools down a nerve to block pain signals. It looks like a small, clear rubber band with tiny channels snaking through it. Marketplace’s Kimberly Adams spoke with John Rogers, a biomedical engineer at Northwestern University who led the research and design of the device. He explained how the technology works and the challenges involved in managing chronic as well as acute pain.
