For the final film in our advent series, the 2012 Christmas Lecturer, Dr Peter Wothers, travels to the Sheffield University MRI Unit at the Royal Hallamshire Hospital to explore how the strange properties of his favourite chemical element are being used to image living lungs.
In the build up to this year's Christmas Lectures, we've published a new video for every day of advent revealing the elements that really excite and inspire people. Explore the Ri's Online Advent Calendar here: http://advent.richannel.org
