parasitic wasp drives zombie cockroach
    #5258710 -

this is pretty freaking cool!

http://www.boingboing.net/2006/02/03/wasp_performs_roachb.html

Ampulex compressa is a wasp that has evolved to tackle roaches, insert a stinger into their brains and disable their escape reflexes. This lets the wasp use the roach's antennae to steer the roach to its lair, where it can lay its egg in it. Parasite Rex author Carl Zimmer tells the story in gooey, graphic detail:

The wasp slips her stinger through the roach's exoskeleton and directly into its brain. She apparently use ssensors along the sides of the stinger to guide it through the brain, a bit like a surgeon snaking his way to an appendix with a laparoscope. She continues to probe the roach's brain until she reaches one particular spot that appears to control the escape reflex. She injects a second venom that influences these neurons in such a way that the escape reflex disappears.

From the outside, the effect is surreal. The wasp does not paralyze the cockroach. In fact, the roach is able to lift up its front legs again and walk. But now it cannot move of its own accord. The wasp takes hold of one of the roach's antennae and leads it--in the words of Israeli scientists who study Ampulex--like a dog on a leash.

The zombie roach crawls where its master leads, which turns out to be the wasp's burrow. The roach creeps obediently into the burrow and sits there quietly, while the wasp plugs up the burrow with pebbles. Now the wasp turns to the roach once more and lays an egg on its underside. The roach does not resist. The egg hatches, and the larva chews a hole in the side of the roach. In it goes.

The larva grows inside the roach, devouring the organs of its host, for about eight days. It is then ready to weave itself a cocoon--which it makes within the roach as well. After four more weeks, the wasp grows to an adult. It breaks out of its cocoon, and out of the roach as well. Seeing a full-grown wasp crawl out of a roach suddenly makes those Alien movies look pretty derivative.

'Pain is meant to wake us up. People try to hide their pain. But they're wrong. Pain is something to carry, like a radio. You feel your strength in the experience of pain. It's all in how you carry it. That's what matters. Pain is a feeling. Your feelings are a part of you. Your own reality. If you feel ashamed of them, and hide them, you're letting society destroy your reality. You should stand up for your right to feel your pain and leave the Shroomery.' ~ Jim Morrison

That's freakin' awesome.... It's amazing that the wasp evolved to the point that it has the capability to surgically alter the roach neuronally. Natures lobotomy experts. Amazing.


I want one. :evil:

That's kinda trippy.

You should check out this article about a type of mind-controlling bacteria that causes it's host to go against it's normal nature (I.E. a bacteria that likes cats, to get into a rat's brain and lure it towards cats). It might be able to corrupt humans too (in a different way of course):
