In the first part of today’s episode we look at some exciting new research into treatments for the degenerative brain condition Parkinsons’s disease. We’ve known since the 1980s that transplants of brain tissue can slow the disease, but the only source was from the brains of embryos created during IVF. Now, scientists have shown they can create stem cells in the lab which can be coached to grow into the right brain tissue by itself before transplant. Could this be an ethical breakthrough, allowing a radical new Parkinson’s treatment without destroying embryos in the process?

In the second half, we think about a question sent in by a listener – why do so many doctors seem committed to futile overtreatment of the elderly in their final years and months? How did the medical profession get stuck into a ‘if in doubt, treat, and always follow the protocol’ culture, and what can Christians who want to avoid needless overtreatment as they die do to prevent this?
