Thinking small can sometimes achieve big things. A new generation of diminutive robots can enter our bodies and deal with medical problems such as intestinal blockages. But do we really want them swimming inside us, even if they’re promising to help? You might change your mind when you hear what else is cruising through our bloodstream: microplastics! 
We take a trip into the human body, beginning with the story of those who first dared to open it up for medical purposes. But were the first surgeons really cavemen?
Guests:
