Edwards currently hosts the podcast Science(ish) alongside Dr Michael Brooks, which delves into the science behind popular films. The series proved such a hit that the duo were commissioned by Atlantic to write a book of the same name, "Science(ish): The Peculiar Science Behind The Movies", which was published in October 2017 and ranked number 1 in the Physics, Cosmology and Humorous Essays Amazon charts for several weeks as well as achieving a position of 21 in the overall book charts. The podcast itself has topped the iTunes Science & Medicine chart.
