How Britain Became Zombieland

Cordyceps unilateralis, colloquially known as the “zombie ant fungus”, is an organism straight out of a horror story.

After inducing its carrier to move from the leaf canopy to the humid forest floor, the fungus fruits from its victim’s head, to infect another generation of zombie ants.
