Slime is an ambiguous thing. It exists somewhere between a solid and a liquid. It inspires revulsion even while it compels our fascination in fiction and on the screen. It is both a vehicle for pathogens and the strongest weapon in our immune system. Many of us know little about it, yet it is the substance on which our world turns.

Sirine Saba reads from Susanne Wedlich’s ground-breaking new book which leads us on a journey through the 3-billion-year history of slime, from the part it played in the evolution of life on Earth to its potential role in climate change and life beyond our planet.

There is probably no single living creature that does not depend on slime in some way. Most organisms use slime for a number of functions: as a structural material, as jellyfish do; for propagation, as plants do; to catch prey, as frogs do; for defence, like the hagfish; or for movement, like snails.

In this first episode, the story of how slime continues to fascinate and terrify us on the page and on the screen. From Dr Who to Ghostbusters, from the disturbing stories of HP Lovecraft to the horror of Stephen King, there is a slime for every time, guaranteed to ooze into our deepest fears.
