But there is something else that makes P. It is a DNA virus that contains a large number of genes — as many as , to be precise. This is in stark contrast with other DNA viruses, such as the human immunodeficiency virus HIV , which only contains about 12 genes in all. The size of giant viruses, as well as the fact that they contain such a large amount of DNA, can make them particularly dangerous, explain the researchers who discovered P.
Yet Claverie and Abergel warn that there may be similar giant viruses buried inside the permafrost that could prove dangerous to humans. Though they have remained safely contained so far, global heating and human action could cause them to resurface and come back to life, which might bring about unknown threats to health. The bacteria — which insects disseminate — infect plants such as goldenrods, which have yellow flowers.
The infection causes the goldenrods to put out leaf-like extensions instead of their usual blooms. Eventually, they only serve the spread of the bacteria. But can humans turn into zombies, too? In the s, Dr. Chavannes Douyon and Prof. Roland Littlewood decided to investigate whether Haitian zombies — reanimated, but mindless humans — were a real possibility. In , the two published a study paper in The Lancet in which they analyzed the cases of three individuals from Haiti whose communities had identified as zombies.
One was a year-old woman who had, allegedly, quickly died after having fallen ill. Douyon and Prof. Instead, medical reasons could explain their zombification. The second person had experienced brain damage, and also had epilepsy , while the third appeared merely to have a learning disability. This is because they are under the delusion that they are dead or decomposing. It remains unclear just how prevalent this condition is, but research suggests that it is a rare occurrence.
Another speaks of a year-old man who had developed a belief that his organs — including his brain — had stopped working, and that even the house in which he lived was slowly but steadily falling apart.
At some point, the man attempted to take his own life. Do such cases mean that zombies are real in some way, or, just as our fascination with the figure of the zombie in folklore and popular culture, do they merely reflect our uneasy relationship with death?

It is one of the greatest fears of humanity, inspired by a bulk of Hollywood movies, and scientists do believe that a zombie outbreak could happen.
While it would be impossible to believe that the dead would rise and feed on the living, experts do think that a parasite could affect the brain or a virus could evolve. A parasite called toxoplasmosa gondii is known to infect the brains of rodents.
Humans became extinct after close to 1, turns and more than 7, zombies were left at the end. There are ways to survive a zombie apocalypse. The best way is to get ahead of the outbreak and move somewhere with a small enough population where you can avoid it. YouTuber Matthew Patrick MatPat looked at pandemic models, global population trends, and agricultural calendars to figure out the best place to go: a tiny little town near Ontario, Canada.
Plus, MatPat is a stickler for using real science to solve fictitious problems; he even figured out the best weapon to use against zombies. I trust him. You just need to get to them before the outbreak starts:. Estately is more light-hearted in their approach than either Tomotani or MatPat. They use different data points largely drawn from Facebook interests and are not at all rigorous in their modeling.
Still, their chart does have similar useful factors for surviving a zombie apocalypse. However, states with high concentrations of people who play zombie video games had a tactical advantage as well because they understood the enemy.
