Johan Eklöf is a Swedish bat scientist on a mission. In The Darkness Manifesto (translated by Elizabeth DeNoma) he warns how light pollution is threatening the ancient rhythms of life. Many creatures across the world come to life at night – with bats specially adapted to fly using echolocation. By keeping the lights on we are disrupting entire ecosystems.
But darkness can appear alien and frightening. The writer Kate Summerscale explores the phobias that haunt the imagination as the lights go off: nyctophobia, xylophobia and hypnophobia – intense and morbid fears of the dark, of forests and of falling asleep.
But why do bumps in the night sound so much more unnerving than during the day? The neuroscientist Professor Geraint Rees focuses his research on seeking to understand the neural basis of consciousness and he explores how our different senses are integral to the way we perceive and experience the world around us.
The forces of light and darkness are pitted against each other in the classic children’s story The Dark is Rising by Susan Cooper, now adapted for BBC World Service radio, starting on Tuesday 20th December. Producer and co-adapter Simon McBurney creates a spine-tingling winter soundscape with the use of binaural sound, giving listeners using headphones a unique immersive experience.
