"The picture was taken by an electrical inspector, who noticed the exocell crawling out of the ocean. The exocell was moving out of the water rather deliberately, giving him an opportunity to take a fairly steady picture before the exocell disappeared into the pipe. After sending the picture out for independent digital image processing, there appears to be a human hand inside the drainpipe."Man, this would have been SO FUCKING COOL if it had been real. Oh well.
The brainworm emits chemicals that alter the behavior of the ant causing the ant to spend inordinate amounts of time hanging out on the tips of grass where it is exceedingly more likely to be eaten by a grazing sheep, cow, deer or rabbit.In fact, dendriticum is not unique in controlling its hosts' behavior, and is interesting to biologists more so because of the "altruism" of the kamikaze, which dies when the sheep eats the ant.
"Rats can usually detect subtle changes in their environment. It makes them very hard to trap or poison but this parasite overrides the innate response - they almost taunt the cats in a sense."Toxoplasma gondii is also found in human brains -- it's unknown whether it similarly alters human behavior, but some studies suggest it does:
the women infected with toxoplasma spent more money on clothes and were consistently rated as more attractive. “We found they were more easy-going, more warm-hearted, had more friends and cared more about how they looked,” he said. “However, they were also less trustworthy and had more relationships with men.”For more, see this post.
By contrast, the infected men appeared to suffer from the “alley cat” effect: becoming less well groomed undesirable loners who were more willing to fight. They were more likely to be suspicious and jealous. “They tended to dislike following rules,” Flegr said.
