One of his recent novels, Solar, Ian McEwan addressed climate change and had a main character who was a Nobel Prize winning scientist.
Talking Today's guest editor - the Nobel Prize winning scientist Sir Paul Nurse - Mr McEwan explained why it is difficult to write about science in fiction and so few novelists were prepared to delve into science.
"I think of literature as an investigation into human nature... an I supposed one part of the biological sciences is involved in a parallel pursuit." Mr McEwan explained.
However, literature does not "actually deepen what we know" he added.
"Daydreaming is a crucial element for novelists and scientist... there I think, we are in each other's' camps."
