Melvyn Bragg and guests discuss the giant molecules that form the basis of all life. Macromolecules, also known as polymers, are long chains of atoms which form the proteins that make up our bodies, as well as many of the materials of modern life. We've only known about macromolecules for just over a century, so what is the story behind them and how might they change our lives in the future? Melvyn Bragg is joined by Athene Donald, Professor of Experimental Physics at the University of Cambridge; Charlotte Williams, Reader in Polymer Chemistry and Catalysis at Imperial College London and Tony Ryan, Pro-Vice Chancellor for the Faculty of Science at the University of Sheffield.
