Les Zombies (document en anglais)

Hi, I'm going to talk about zombie. Can human really become zombie? Several scientists have studied on this subject. They have concluded they’re some situation where it could happen.

First, there are many brains parasites in our planet that can turn victims into mindless slaves. For example, the Toxoplasmosa has been found to have the ability to change the behavior of its host. This parasite can only breed inside the intestines of a cat. Therefore, it infects rats to seek out arenas marked with cat urine so that it will be able to proliferate if a cat eats the infected rat. The findings of behavioral alteration in rats and mice have led some scientists to speculate that Toxoplasma may have similar effects on humans. Humans and rats aren't all that different. That’s why they use them to test our drugs. This lead us to ask ourselves; «what will happen, if a more evolved version of Toxoplasmosa do to us the same thing it does to rats?

The second reason that it could happen is around neurotoxins. There are certain kinds of poisons that slow your bodily functions to the point that you'll be considered dead. For example, the case of Clairvius Narcissi, in Haiti. A man that said he’s been turned into a living zombie by a combination of drugs. He was declared dead by two doctors and buried in 1962. They found him wandering around the village 18 years later. It turned out the local voodoo priest had been giving a dose of chemical mixtures containing tetrodoxin (pufferflish venom) and bufotoxin (toad venom) to induce a coma which mimicked the appearance of death. He was then allowed to return to him, where he collapsed, "Died" and was buried. His body was then recovered and the victims can be brought back under the effects of the drug Datura straomonium to create a compliant zombie-like state and set to work on a plantation.

Nano-bots are microscopic, self-replicating robots can invisibly build or destroy anything. Vast sums of money are being poured into nanotechnology and at some point; scientists know Nano-bots will destroy mankind. They just don't know how yet. How it can result on zombies. Scientists have already created a Nano-cyborg, by fusing a tiny silicone chip to a virus. The first thing they found out is these cyborgs can still operate for up to a month after the death of the host. According to studies, within a decade they'll have Nano-bots that can crawl inside your brain and set up neural connections to replace damaged ones. Those Nano-bots will be programmed to keep you functioning/functional after you die. They can also form their own neural pathways, meaning they can use your brain to keep operating your limbs after you've deceased. The Nano-bots will be programmed to self-replicate, and the death of the host will mean the end of the Nano-bots. To preserve themselves, they'd need to transfer to a new host. Therefore, the last act of the Nano-bot zombie would be to bite a hole in a healthy victim, letting the Nano-bots steam in and set up camp in the new host. Once in, they can shut down the part of the brain that resists (the cortex) and leave the brain stem intact.

But those are all speculation and
