Their host is a shrimplike crustacean called a gammarid. Gammarids, which live in ponds, typically respond to disturbances by diving down into the mud. An infected gammarid, by contrast, races up to the surface of the pond. It then scoots across the water until it finds a stem, a rock or some other object it can cling to. The gammarid’s odd swimming behavior allows the parasite to take the next step in its life cycle. Unlike baculoviruses, which go from caterpillar to caterpillar, thorny-headed worms need to live in two species: a gammarid and then a bird. Hiding in the pond mud keeps a gammarid safe from predators. By forcing it to swim to the surface, the thorny-headed worm makes it an easy target. Simone Helluy of Wellesley College studies this suicidal reversal. Her research indicates that the parasites manipulate the gammarid’s brain through its immune system. The invader provokes a strong response from the gammarid’s immune cells, which unleash chemicals to kill the parasite. But the parasite fends off these attacks, and the host’s immune system instead produces an inflammation that infiltrates its own brain. There, it disrupts the brain’s chemistry — in particular, causing it to produce copious amounts of the neurotransmitter serotonin. Serotonin influences how neurons transmit signals. Dr. Helluy proposes that the rush of serotonin triggered by the thorny-headed worms corrupts the signals traveling from the eyes to the brain. Normally, an escape reflex causes the gammarid to be attracted to the darkness at the bottom of its pond. Thorny-headed worms may cause their host to perceive sunlight as darkness, and thus swim up instead of down. Whether humans are susceptible to this sort of zombie invasion is less clear. It is challenging enough to figure out how parasites manipulate invertebrates, which have a few hundred thousand neurons in their nervous systems. Vertebrates, including humans, have millions or billions of neurons, and so scientists have made fewer advances in studying their zombification.
However, there is no known food that supplies all the needs of human adults on a long-term basis. Since Taylor is determined to follow a one-food...

Read More »One material that's pretty much guaranteed to keep zombies away is concrete. If done right, they undead can't bite through it and they can't knock it down, even when traveling in great numbers.
You hear low moaning and the shuffling of slow feet. No, it's not the line at the Apple Store on iPhone release day. That zombie apocalypse we've been hearing so much about is finally here. You're not worried, though. You have a concrete safe house, a zombie-proof bike, a survival kit and death-scented cologne to hide you from the undead. We've rounded up everything you need to coast through zombie Armageddon. A log cabin might not sound like the most secure choice of safe houses, but you'll survive the end days in style if you own the $113,000 (£69,995, about AU$129,000) Zombie Fortification Cabin from Tiger Log Cabins. It offers all the creature comforts (Xbox, TV, toilet, microwave) you could want while also keeping undead creatures out thanks to reinforced windows, barbed wire, escape hatch and arsenal storage. Flame throwers, water cannons and search lights will cost you extra. Tiger Log Cabins is ready and willing to stand behind its product by offering a 10-year anti-zombie guarantee. If you try to collect on that guarantee, you'll need to provide medical evidence of a genuine zombie outbreak. Fair's fair. At least you will have lived to tell the tale.
