Our final Q&A episode of the year tackles two medical ethics questions in the news recently. The first is Wegovy, the ground-breaking anti-obesity drug which has been a controversial sensation in the United States. It is now available (in very limited supply) on the NHS here in the UK, but only for those with quite serious obesity with BMIs of 35 or higher. Should Christians hail this a brilliant medical advance tackling a serious public health issue, or a worrying example of big pharma trying to medicate away our self-control? Next, we discuss a new push by some scientists to soften the ground ahead of a campaign to extend the current 14-day limit on human embryo research. Why do researchers want to keep embryos alive in petri dishes for longer, and will it actually benefit any of us in the end really?
