This week on the show we delve into some controversial medical science. First up Chris revisits the research on Hydroxychloroquine, also known as Donald Trump's favourite COVID-19 medication, and the most recent research about this treatment that has come out, and subsequently been retracted. Also this week Stu brings us up-to-date on CRISPR and what medical advances are currently being made, and what could be done in the future using this incredibly powerful gene editing technology.
