A photo from open sources Well, who doesn’t like the good old secret, especially if it baffles scientists? Popular Editor Science Cliff Ransom recently performed as moderator in a discussion about such seemingly inexplicable phenomena on San Diego Comic-Con Festival. The discussion took place on the occasion of Science Debut On Inexplicable: Special materials “, which will premiere today, July 29. We thought and decided that this is an excellent occasion to ask: what phenomena science does not can explain so far? Below are five of our favorites and seemingly eternal riddles. 1. Why do people yawn? You yawn, yawn, we all yawn. When you start reading or thinking about this, you probably have the urge to yawn. (Not yet yawned?) You can even “catch” yawning from other people and from animals such as dogs. Thank you, biology, but which does yawning function? There are many ideas on this subject, but none of They do not stand up to scientific verification. There is speculation that yawning helps cool the brain by increasing blood flow to the jaw, neck and sinuses, and then removing the warmth of the blood with a deep breath. it very illogical, but a person yawns less often in hot weather when air does not cool the body so much. In short, yawning disappears when we need it most, “stated WebMD Dr. Adrian Guggisberg. There is one more a hypothesis that has not yet been abandoned: that yawning “is a signal to our body to cheer up and not relax, “wrote on the pages of the New Yorker Maria Konnikova. After yawning usually occurs increased mobility and physiological activity, and this indicates a certain “awakening” of a person. And why Is yawning contagious? Recently conducted by PLoS ONE Magazine the study found this to be a kind of demonstration empathy. But another study showed that everything is just vice versa. Like this. 2. Ghosts
Okay, you say, everything is clear about yawning, but ghosts can not be. However, a significant number of Americans – 48 percent, to be precise – believes that there are. Talk about it The results of a CBS News poll conducted in 2005. In ghosts Most women believe – about 56 percent. And every fifth of the numbers polled by CBS said it saw a ghost or sensed it presence. Modern scientists are not particularly active in this a topic, but several compelling explanations do exist. One of which relates to infrasound, or to low-frequency sounds, which are inaccessible to human hearing, and which produce storms and Appliances. Such noises create vibration in human organs, which makes people feel anxious. Vibration from infrasound can also interfere with normal vision, and in humans it seems that he sees some things. There is one more theory – that drafts create “cold spots” that seem man perfume. Finally, there is the hypothesis that visions of ghosts caused by hallucinations, the cause of which is carbon monoxide poisoning gas. 3. Déjà vu. You probably had this feeling: something happened, and it seems to you that this has already happened to you. What is the reason for this strange deja vu feeling? In short, then surely no one knows this, however some ideas on this subject exist. The authors of one study in which people placed in a virtual computer world, hinting at what a feeling occurs most often when a person enters a place, very similar to another where he once visited, but which is not will know. “One of the reasons this thrill is that accompanied by deja vu, may lie in the contrast between a sense of novelty and a simultaneous sense of something old; something a stranger that seems familiar, but should not be so, “- told Scientific American psychologist from state university Colorado Anne Cleary. In another study it turned out that one healthy man from among the experimental strong and repetitive deja vu sensation when taking two cold medicine. Deja Vu can also occur when the brain incorrectly encodes a new memory, or when it misfires, creating the feeling of something familiar. 4. Bigfoot
Bigfoot has many names – a sasquatch in the northwest coast, yeti in the Himalayas, “wild man” in Central Asia and yovi (my favorite) in Australia. But he is known to science under the name cryptid is an animal whose existence is not proven. Irrefutable evidence of the existence of Bigfoot is not there is, however, scientists say, “lack of evidence there is no evidence of absence. “Many people believe take big animals such as bears for a snowman. In a recent study, DNA from hair was studied, which supposedly belonged to a large humanoid beast. It turned out that this is the hair of “raccoon, sheep, bear, dog, human and so on, “reports the New York Times. As you can see, Snowy there is no person on this list. 5. The placebo effect of course you know about the placebo effect. If you truly believe that something will have a somatic effect on you (say, it will quench pain), something really works – even if it’s just no pharmacological slice of sugar exposure. For this reason, harmless and useless substances. used in all official medical research to show whether or not the medicine has any effect other than psychological. The placebo effect is actually more mysterious, what it might seem. Recent works show that he is acting even when the patient is told that he took sugar a pill. The same goes for sleep. If you think that slept better last night compared to other people, who slept exactly the same, you better prove yourself when deciding a variety of tasks. There are several explanations of how it works. placebo effect. For example, the authors of one study found that there were fewer people using fake analgesic ointment activity in that part of the brain that feels pain. There was also found that a similar fake ointment activates cells spinal cord. But how exactly is this manifested in numerous cases from infection control and increased rates to exams to improve sleep – no one knows.
