Riddles of man 2024, March
Children call him "Eternal Grandfather". I can't even imagine how old he is. We sometimes see him on the difficult path - from home to store. It's about half a kilometer, and it takes my grandfather half a day. This is his job and cannot be canceled
Life expectancy is largely determined by genetic predisposition - which means it can be predicted based on genetic screening.At one time, the journal Science published the results of an unusual study: having studied only 150 genetic variations (single nucleotide polymorphisms), scientists are able to predict with almost 80% accuracy who will be able to live to a ripe old age
Scientists have finally decided what exactly can be done to prolong youth.The path to longevity is thorny, but completely surmountable. No supernatural effort is needed - only willpower. You cannot do without it in order to eat right and move at least a little
An unexpected discovery was made by ordinary users of social networks - humanity has ceased to age. It all started with an ordinary flash mob where people shared photos of their ancestors. Someone noticed that our 20-year-old grandparents often look older than their current 30- and 40-year-old grandchildren
Physical immortality is a long-standing dream of humanity. For no matter how much the great religious teachings tell us that death is just a transition to another world, the fact of the matter is that you do not want to cross. The vast majority of people who live are quite happy with this world
The whole life of a person: all his achievements, experience and knowledge, all this is stored in memory. But where is the memory itself stored? We used to think that memories are somewhere in our heads, but scientific research suggests otherwise
The ability of modern medicine to keep us alive makes us think that human evolution has stopped. Improving health care is destroying a key driving force of evolution, as some people live longer than they could in their natural environment, making it more likely that their genes will be passed on
For Europeans, Chanel perfumes are considered pleasant, while New Guineans hate this smell, but adore the amber of pork fat. How is it that different nations evaluate smells differently? Does the smell conceal only the taste aspect, or is there something else behind it?
The Wendigo is a very strange, frightening creature whose essence is very blurred. It is a large part of the folklore of the Algonquin Indians living in Canada.Most often, wendigo is represented as a forest monster - tall, insane and violent
The history of the twentieth century knows many dictators whose names, even decades after their overthrow or death, compatriots pronounce with fear, hatred or contempt
The method of counting the number of ideas opens a window into the "black box" of the mind.Reading other people's thoughts - what could be more interesting ?! Today, decoding the electrical signals of the brain, scientists in the most general terms are able to distinguish the content of thought - whether a person is in front of him someone's face or a multi-storey building
Do you often have nightmares? If not, then my friends and I envy you with white envy. Most people I know suffer from midnight horrors. And it would be fine if they were just some kind of phantasmagoric plots, but no
In the southwestern part of China, in the Sichuan province, there is a small village of Yangxi. It is closed to tourists, and a little less than a hundred people live in it. But almost half of the entire population of this village is dwarfs, whose height does not exceed 117 centimeters
Handwriting is a mysterious thing: many are convinced that the squiggles on paper can be used to judge a person. We decided to find out if this is really so.At school, children are taught to write according to the same pattern, but, despite this, everyone succeeds in different ways
You've probably heard about cases of spontaneous combustion of people, which are clearly impossible to explain, although scientists have different versions of this phenomenon. Quite strange is what is often said about the safety of clothes and things that were worn on a person or were next to a suddenly flaming person
Most schoolchildren suffer from loneliness and cannot live without social media. These are the results of a poll conducted by the All-Russian Popular Front. The study covered almost 80 regions of Russia. What is the reason for this state and behavior of adolescents
Scientists at Tufts University (USA) have found that the carotenoid pigment lycopene found in tomatoes reduces the risk of fatty liver disease, cancer and inflammation. This was reported in a press release on MedicalXpress
Lightning, the nature of which still remains a mystery to scientists, hides, among others, another secret: sometimes, falling into a person, they, instead of killing, heal him or endow him with superpowers. This is what we'll talk about today
About 5% of people without mental illness also see or hear something that does not exist from time to time.The study involved more than 31,000 people from 18 countries from all continents. A prerequisite was the absence of mental illness. The survey and data systematization was carried out by an international team of experts led by scientists from the Brain Institute in Queensland and Harvard Medical School; the results can be found in JAMA Psychiatry (2015)
Perhaps you believe that your body and mind are yours alone. In fact, you are a fusion of many organisms - possibly including another person, says BBC Future.Once upon a time, there was a very simple description for human origins: a man and a woman met, had fun, and then - relatively quickly - a tiny fertilized egg turned into a screaming newborn baby
The result was encouraging, although not entirely accurate.Scientists have speculated that meditation has a beneficial effect on the cardiovascular system several years ago. A group of American physicians led by Dr. Chaikrit Kittanavong tried to build an evidence base for these assumptions and conducted a study using data from surveys of more than 61,000 US residents, almost 6,000 of whom, that is, about 10%, practiced meditation in one form or another
The need to sleep a whole third of the day every day must be justified by something, right? Scientists have studied sleep for decades and can now explain some of the processes that occur in sleep.So what does the brain do in sleep?- Salik
“When I wake up, I realize that I cannot move. I try to say something, but I can't. I can very clearly hear everything that is happening around me. Sometimes I can open my eyes to see what is happening in front of me. Sometimes I get scared, and I try to fight, but nothing comes of it. I
The phenomenon, which is called apophenia - from the Greek "I make it manifest", otherwise also called "false realization". This term was proposed by the German scientist Klaus Konrad in 1958. He described the acute stage of schizophrenia, during which unrelated details of the surrounding reality and their perception are united in the patient's mind by strange common signs and meanings, which, as Konrad believed, are born only in a diseased brain
A simple experiment with a computer screen showed that women are noticeably less responsive to movements and are slower to recognize them than men. Scientists who published an article in the journal Current Biology write about this
The study authors also found out how long this condition lasts. Some of their patients after clinical death were able to tell scientists that during the "blackout" they heard the doctors and could fragmentarily retell the staff negotiations
According to scientists, about a third of birds and plants actually look different than we think. It's just that people do not distinguish between their real colors. In humans, there are only three types of cones in the eye - light-sensitive cells of the retina, in birds - four
Our vision, like all other senses, is malleable and variable depending on experience. Take, for example, those cases when people who are deprived of one sense experience a compensatory increase in others - for example, in the blind, sense of touch and hearing are sharpened
Each of us (if he is not color blind) is sure that he is well versed in colors. Men at least distinguish blue from orange, and as for women, their ability to see a dozen or two shades of, say, red nail polish always shocks a strong half of humanity
The opinion that the eye is like a camera is, of course, not without foundation. At the same time, we know that there are other optical instruments that "see" something else - a microscope and a telescope. Why, then, do we prefer only one reality and neglect others?
The human body contains many components that are interconnected. Vision is one of the main organs of perception that allows you to navigate in space. Thanks to him, the brain receives information about the environment, recognizes objects, estimates the distance to them
The authors of the paper, published in the Journal of Vision, described the phenomenon of visual processing failure. It occurs if more and more visual signals begin to arrive at the neurons that process images at too high a speed. Because of this, a "congestion" occurs, the neurons cannot cope with the flow, and some images begin to "fall out" before reaching the level of consciousness
Optical illusions, in short, are direct confirmation that our brains are damn lazy. He does not carefully analyze each trick picture, but interprets it on the basis of previous experience, thereby misleading us. People created optical illusions long before they deciphered the mechanism of their work
British scientists have compiled from the words of a born-blind rock musician, the first-ever account of psychoactive substance-induced hallucinations of a person who has never seen a single color in his life
The absolute lack of vision is not at all a reason to fall into depression - some people completely replace it with echolocation
The fact that visually impaired or blind people hear much sharper and better than sighted people has long been known. However, the specific processes occurring in the brain of such people have not been studied until now. Some of the questions were answered by researchers from Oxford and the University of Washington
Perhaps this will force you to reconsider some of the views on life. 1. Poor-quality bedding Just think - every night you touch the fabric for 6-8 hours
The entopic effect of the blue sky or the so-called Shearer effect consists in the fact that, looking with a defocused gaze, into the clear blue sky, you can see many small light points flying with a train along a small trajectory, and then quickly extinguish like sparks
When you think about something, it is likely that it appears to you in one of three forms: a specific object (for example, a cup or planet), something that you can distinguish when you look at it (for example, a color), or something abstract
Many blind and visually impaired people are helped to determine the position of objects in space by special sound signals. They turned out to be much shorter than previously thought
