The zombies have come, but it’s not exactly the apocalypse. Carpenter ants being taken over by fungi sounds like the beginning of a Science-Fiction film, but this time it’s just Science. From Discovery Magazine:

This cryptic cycle has been going on for at least 48 million years.
In a study forthcoming in Biology Letters, Harvard’s David Hughes argues that a fossilized leaf found in a fossil-rich part of Germany’s Rhine Rift Valley bears the scars of the ant’s trademark death bite.
