The Fungus That Turns Ants Into Zombies

Somewhere in a rainforest, an ant climbs to a height it would never normally choose, bites down on a leaf vein, and waits to die — because a fungus has quietly rewritten its behavior from the inside. This is Ophiocordyceps, the real parasite behind The Last of Us, and its actual biology is stranger than the fiction.

    The Attenborough sequence that launched a thousand nightmares — and directly inspired The Last of Us. Watch the fungus erupt, in real macro footage, from a dead ant's head.

  2. Ophiocordyceps unilateralis

    The scientific dossier on the zombie-ant fungus, first described by Alfred Russel Wallace in 1859. Note the eerie detail: it leaves the brain intact and controls the muscles directly.

    National Geographic's Amazon footage of the fungus commandeering an insect's body to reproduce. Each Cordyceps species targets just one host — a lock-and-key horror.

  4. How a cordyceps fungus turns ants into 'zombies'

    The play-by-play of the takeover: how the fungus forces the fabled 'death grip' at the perfect height, temperature, and humidity to launch its spores.

    A tidy primer from the LOC on the whole grim lifecycle, plus the counter-move: healthy ants haul infected nestmates far from the colony before the fungus can bloom.

    The question everyone asks after the show. Scientists weigh in on the one thing that (probably) protects us — and the caveat that makes them hesitate.

    A biologist walks through the actual evolutionary hurdles — body temperature, host specificity — that stand between the ant fungus and a human pandemic.

  8. The zombie fungus from 'The Last of Us' is real — but not nearly as deadly

    NPR's reassuring-but-not-entirely coda: the real threat from fungi isn't zombies, it's the drug-resistant infections quietly rising in a warming world.
