Sherlock and Dr Who writer Steven Moffat, and Lucy Caldwell, winner of the BBC National Short Story Award, discuss writing short stories inspired by the science of the Large Hadron Collider for a new collection called Collision. The project pairs a team of award-winning authors with Cern physicists to explore some of the discoveries being made, through fiction. From interstellar travel using quantum tunnelling, to first contact with antimatter aliens, to a team of scientists finding themselves being systematically erased from history, these stories explore the dark matters that only physics can offer answers to.

A new documentary called Subject explores the life-altering experience of sharing one’s life on screen, through the participants of five acclaimed documentaries. Samira Ahmed talks to Camilla Hall, one of the film’s directors, about the ethics of documentary making.

Writer Mojisola Adebayo and director Matthew Xia talk about their new play Family Tree, which won the Alfred Fagon Best New Play Award. The play, which opens at the Belgrade Theatre Coventry, explores the extraordinary story of Henrietta Lacks, the African American woman whose cancer cells were taken without her permission or knowledge in 1951 and which are still informing medical science today.
