Building Bodies and Mending Broken Hearts

13 September 2009
Presented by Ben Valsler, Kat Arney.

This week we find out about bionic bodies. We discover whether it's possible to mend a broken heart with stem cells as well as investigate if soft nanobots could soon be delivering drugs around our bodies. We also bring you the highlights from this years British Science Festival. Plus, in Kitchen Science, we hit the kitchen to investigate one of natures composite materials - a chicken bone!
