Fear of imminent death is one of the most unpleasant feelings for many people, especially for those who are afraid of dying alone. And as scientists have found, people have every reason for such fears.
According to a study by scientists at New York University Langone Medical Center, the moment of dying - if you can call it that now - is something completely different than people previously thought.
It turns out that the dead are still conscious for some time even after the official declaration of death. And moreover, they understand that they have died and fully feel the world around them.
This was discovered by a group of researchers led by Professor Sam Parnia. For many years, his team has been monitoring the condition of dying people, and also collecting testimonies from those who have experienced clinical death. After many years of work, the authors collected the data, summarized it and published the first results.
The main conclusion of the study: after the official declaration of death - that is, after cardiac arrest - the human brain still functions and remains active. The mind lives. This means that in most of these cases people can understand that they have died.
In this case, the deceased feels that his body no longer responds to external stimuli. Even if he wants to move his hand, his own body will not listen. A person seems to feel like a prisoner in his own body. He hears words, sees those around him, but can no longer give them a sign.
Some of the patients after clinical death were able to tell scientists that during the “blackout” they heard doctors and could fragmentarily retell the conversations of the staff.
As it turns out, death is something completely different from what we previously thought.
Scientists explain their findings by saying that the brain dies more slowly than the heart, so a person, his mind, lives for some time even after death is declared.
According to the American Heart Association (AHA), the terms "cardiac arrest" and "heart attack" are often used interchangeably, but they are not identical. During a heart attack, a blocked artery often prevents blood from reaching only one part of the heart, which can lead to the death of that particular part - although the heart as a whole continues to beat. During cardiac arrest, the electrical signals that drive the heart are disrupted, the heart stops beating, and death occurs.
In the vast majority of cases, doctors determine death based on the fact that the heart is no longer beating, explains Professor Sam Parnia, director of critical care and critical care medicine at the NYU Langone School of Medicine: “This is how the time of death of a person is determined in most cases.”
And it is from the moment the heart stops that blood stops flowing to the brain - its work slows down.
Slows down - but doesn't stop!
This slowing of the chain reaction of cellular processes that ultimately leads to the death of cells throughout the brain can take several hours after the death of the heart.
And the work of the cerebral cortex - the so-called “thinking part” - will continue all this time, albeit slowly. A person lives and feels.
And this means that what is usually called death (cardiac arrest), according to doctors, is just its first phase.
The brain dies more slowly than the heart, so a person lives for some time even after death is declared.
The study by scientists from New York confirms the results of an earlier discovery made by Canadian specialists from the University of Western Ontario. Then it was also stated that life after death is far from over: after the cessation of the work of many organs, the brain still continues to work, and for quite a long time.
BY THE WAY
Modern medicine, however, previously knew that the brain dies later than the heart (thanks to which, for example, heart transplantation became possible; today this operation is carried out successfully in many countries). However, it was believed that if the vital activity of the brain is not supported with special medications, the brain will soon die along with the heart. And now a study by scientists from New York has shown that this time is much longer.
But a team of doctors from Haddassah Hospital in Jerusalem analyzed the stories of people who were close to death and found that the return to memories of life may be associated with the part of the brain that stores memories. Doctors believe that this part of the brain is the last part affected by oxygen deficiency and blood loss. Therefore, it is able to work even when a person loses consciousness and slowly dies.
Doctors note that often the memories of dying people are especially emotional. At the same time, there is no linear progression between memories; a person cannot answer why these particular memories came to him and not others.
The world is actually a little different from how we see it.
1. Temporary blindness
The peculiarity of our vision is its discreteness (discontinuity). The reason for this is saccades. These are micromovements of the eyeball performed simultaneously in one direction. During them, a person becomes blind - he does not see anything. Vision seems to be paused.
We don't notice that vision is discrete because our brain itself fills in the gaps. He completes the picture, fills in the missing fragments, and imagines.
Saccades are needed in order to constantly change the angle of view a little bit. We see because the brightness of the objects around us changes.
How does it manifest itself?
Our eyes are constantly scanning the surrounding space, looking for something to latch on to. It should be something contrasting - a bright spot, a protrusion, details. That is why it is pleasant to be in the forest, where there are many contrasts, to look at objects and various elements that are interesting from an architectural point of view.
But monotony, homogeneity, the absence of elements that the eye could catch on to, seems boring to us.
2. Time stretching
Saccades have an interesting effect. After them, we can feel time slowing down. This phenomenon is called chronostasis.
How does it manifest itself?
If you look at the second hand of an analog watch jumping from division to division, its first movement will seem slower than subsequent movements. This happens because the brain slows down a little after a saccade. There is an illusion of time being stretched out.
An experiment related to the perception of time was conducted by American scientists Chess Stetson and David Eagleman. They gave participants wrist displays with large, constantly changing numbers. At low frequencies they could be easily distinguished. And when the speed of change increased, the numbers merged into a homogeneous background.
Scientists have tried to prove that if a person is stressed, he will begin to see individual numbers again. According to their hypothesis, the brain perceives time differently in critical situations. The subjects jumped from a height of 31 meters onto a safety net. The experiment was not a success, however, most likely, the stress was not as strong as required: people knew that there was insurance below and they would remain unharmed.
3. Hidden blind spots
The human eye has a blind spot - an area on the retina that is insensitive to light. There are no light receptors in this place due to the structural features of our organ of vision. But we don’t notice this because our brain deceives us.
How does it manifest itself?
When we look with both eyes, blind spots are invisible. The same thing happens if you close one eye. In this case, the brain “loads” the image it takes from the other eye.
But it is still possible to detect a blind spot. Use this picture:
Close your right eye and look with your left eye at the right cross circled.
Without blinking, move your face further or closer to the monitor.
With your peripheral vision, watch the left cross, without moving your gaze to it.
At a certain moment, the left cross will disappear.
4. Different color perception
Central and peripheral vision perceive colors differently. The thing is that there are two types of light-sensitive elements in the eye - cones (they distinguish colors better) and rods (they have higher light sensitivity). The place of maximum accumulation of cones is the center of the eye. There are more rods on the periphery.
This is where the peculiarity of our vision arises. Peripheral vision allows you to see in semi-darkness and darkness. It better captures bright, contrasting colors, such as black or red. But he perceives other shades worse.
How does it manifest itself?
Despite the difference between central and peripheral vision, we see a complete picture. The final image is created by the brain, which thinks it out and constructs it from existing data. And it’s not a fact that he doesn’t make mistakes and doesn’t distort reality.
5. Special perception
It is a psychological theory that states that we perceive the environment and events in it in terms of their ability to act. And this creates interesting visual illusions.
How does it manifest itself?
Tennis players feel that the ball is moving slower if they hit it successfully. If a person needs to catch a ball, it will appear larger to him. Mountains look steeper if you plan to climb to the top with a heavy backpack.
Visual perception is influenced by the speed of movement, shape, size of objects, as well as actions: hitting, intercepting, throwing, and so on. All this helps to survive. And if you want to see what an object looks like in reality, use a camera.
6. Upside-down vision
In fact, the image reaches the retina upside down. The cornea and lens are collective lenses that, according to the laws of physics, turn objects upside down. Information enters the brain, and it processes and adapts it - so that we see the world as it is.
How does it manifest itself?
There is a simple but revealing way.
Press your finger on the outer edge of the lower eyelid of your right eye. In the upper left corner you will see a spot. This is a real, upside-down image of your finger - as the eye perceives it.
The brain is able to adapt our vision. In 1896, University of California doctor George Stratton created an invertoscope, which inverted the image of the surrounding world. Anyone who wore this device saw objects as they appeared on the retina.
Stratton found that if you wear an invertoscope for several days, the visual system adapts to the inverted world, and disorientation decreases. This way you can train your spatial abilities.
The idea that our entire world and all of reality is just a computer simulation created by some highly developed beings has been exciting the minds of scientists since computers became powerful enough to process large amounts of data. The further into the future, the more powerful and efficient our computing systems become, and the more supporters the theory of computer simulation of the Universe gains.
The idea that we are living in a computer simulation has recently been expressed by prominent scientists, “technological” businessmen like Elon Musk, and even representatives of large banks. But not all experts share this opinion, and their argument is based on the fact that the number of possible interactions of all elements of our world is so great that physical laws simply do not allow even a single hypothetical system to process the entire amount of information.
To prove that it is impossible to create simulations of such complex systems even in theory, a group of scientists from the University of Oxford turned to the problems of calculating quantum effects. An incalculable number of particles throughout the Universe interact with each other at the quantum level every moment, the results of which can often be calculated only by a probability distribution. In particular, physicists proposed to consider the so-called quantum Hall effect, characterized by the appearance of an electric current in a metal under certain circumstances. Trying to describe quantum interactions in matter using modern techniques, scientists have come to the conclusion that even simulating a few electrons requires an extremely powerful system. Moreover, the complexity of calculations increases exponentially as new particles are added. The researchers came to the conclusion that when simulating the quantum Hall effect, there would not be enough matter in the entire space to store information about the interactions of even a few hundred electrons! And this is just one of many other quantum effects. Thus, physical limitations stand in the way of computer modeling of our world, which should reduce the ardor of supporters of the theory of reality simulation.
However, it should be noted that we are talking about modeling a system from a world with exactly the same physical laws as ours. That is, it is unlikely that a computer simulation of our reality is carried out by creatures living in a world with exactly the same parameters. But the possibility remains that we, our entire world, are a matrix created by someone from a completely different reality, where different physics works, allowing us to carry out the necessary calculations. We cannot exclude the possibility that some limitations are specially built into the simulation model, preventing us from seeing simpler ways to calculate quantum effects.
British scientists once found that British scientists are the smartest. And this is not a newspaper joke at all, such a study was actually carried out. Here is a selection of the most interesting and absurd things that British scientists have been doing.
Bowling is dangerous to your health.
This research took about two years and 250 thousand pounds sterling. Scientists have found that while playing bowling, children or teenagers can start running along the lanes and end up getting stuck in the mechanism that sets the pins. The publication notes that such cases have not been recorded previously, however, according to scientists, there is a high probability of such situations occurring. In addition, the Health, Safety and Health Administration report also noted that adults would be at just as high a risk if they decided to walk down the lane and knock down a pin with their hand.
To be successful with men, a woman must expose 40% of her body surface.
Scientists at the University of Leeds, England, have found the answer to a question that has troubled women and men for centuries: where exactly is the line between too modest and too frivolous women's clothing. The study is based on observations made by four researchers who secretly observed patrons of the city's largest nightclub from a balcony located above the dance floor. The study's authors observed how many men approached girls asking them to dance, dividing the girls by the amount of clothing they were wearing. According to research, the ideal ratio of bare skin to clothing is 40:60. At the same time, women who were naked were less successful than women who were dressed too modestly.
Pets pollute the planet more than cars.
British scientists Brenda and Robert Weil published a book with the shocking title “Time to Eat Dog?” This phrase came to us from the times when people conquered Antarctica. In cases where food ran out, travelers had to eat sled dogs. The authors have a message to the reader: at a time when natural resources are depleted, pets become a luxury that, for the sake of the planet, we cannot afford. According to the Weils' calculations, on average each dog needs 164 kg of meat and 95 kg of grain per year. To produce these products, 0.84 hectares of area is required (1.1 hectares for a German Shepherd).
According to scientists, to build and drive an SUV for 10 thousand km, energy in the amount of 55.1 gigajoules is required. And one hectare of land can produce energy equal to 135 gigajoules per year. In other words, the polluting impact of a car on the environment is half that of a dog. Similar equations apply to other pets. It turns out that a cat consumes as much energy (in terms of hectares - 0.15) as a large van, a pair of hamsters with 0.28 hectares is comparable to a plasma TV, a red fish (0.00034 hectares) consumes energy as two mobile phones.
British scientists have realized why grandmothers exist.
A large-scale study in villages in Japan, Ethiopia, Gambia and Malawi, cities in Germany, England and Canada was carried out by anthropologist Leslie Knapp together with colleagues from the University of Cambridge. An article about the research was published in the journal Proceedings of the Royal Society. After collecting some historical data and studying the features of modern life, Leslie Knapp proposed the X-chromosomal “grandmother hypothesis”. A meta-analysis in the study found that grandmothers who live close to their grandchildren influence the survival rate of their grandchildren. According to anthropologists, after reproductive age, women are able to better protect their genes, that is, the inherited parts of DNA. Losing the opportunity to care for her own children, the woman switches to caring for her grandchildren. At the same time, she passes on the accumulated experience to her grown children.
A woman passes on about 31% of her genes to her own sons' daughters. Sons' sons inherit only 23% of their grandmother's genes. Grandchildren by daughter (of both sexes) are approximately in the middle - 25%. If we talk about the X chromosome, then the son's sons have nothing to do with their grandmother at all (they receive their X chromosome from their mother). The closest to the grandmother are again the son’s daughters.
The myth of Santa Claus owes its existence to hallucinogenic mushrooms.
English scientists believe that the myth of Santa Claus traveling on flying reindeer owes its appearance to hallucinogenic mushrooms that the inhabitants of Lapland loved to indulge in. It is known that the story of Santa Claus was born in Lapland, in the north of modern Finland. Lapps lived there, who, as scientists found, quite often drank the urine of deer that ate fly agarics. In laboratory conditions, scientists obtained a powerful hallucinogenic substance from these mushrooms. It is no wonder, scientists believe, that the Lapps imagined flying deer, which then turned into the legend of the good Santa Claus. Scientists explain the bright red robe of the New Year's character with the color of a hallucinogenic mushroom. The red and white color of the fly agaric turned in the inflamed imagination of people into an old man in a red caftan with a white beard.
Miniskirts prolong life.
The less clothes a woman wears, the longer she lives - British scientists came to this interesting conclusion under the leadership of anthropologist Sir Edwin Burkhart. More than 5,000 women over 70 years old took part in the study. The result of the analysis amazed anthropologists: the less clothing the respondent wore, the more likely she was to live to an old age.
Scientists have several theories to explain this relationship. First, clothing contains residue from chemicals used during cleaning and washing, which, when reacting with sweat, can form compounds that penetrate the skin and negatively affect health, including the development of cancer. Secondly, a woman in revealing clothes attracts men and is more likely to get married. It is known that the health of married people is better and they live longer than single people. Thirdly, women who wear minimal clothing are exposed to natural factors that affect longevity. Fourthly, according to British scientists, such ladies are more open, intelligent, independent and take more care of themselves. Fifthly, lovers of revealing outfits are more likely to have sex, which, from the point of view of researchers, is another beneficial factor affecting longevity.
Communication reduces the risk of heart attack, stroke and flu.
Social activity is as important to maintaining a person's health as exercise, diet or medication. The results of a study by British and Australian scientists are published by the London newspaper Daily Express. Active communication within various social groups and teams helps reduce the risk of myocardial infarction, stroke and even influenza. The publication cites the results of a study by Professor Jolanda Jetten from the Australian University of Queensland, according to which enthusiastic conversations at the table, including in restaurants and cafes, increase brain activity, which has the most positive effect on health.
The smartest scientists live in the UK.
British scientists are the most productive in the world. According to the study, the UK ranks second after the US in the number of scientific discoveries and developments made per year. Comparing this with the amount of funding for the scientific industry and the number of people working in it, we can conclude that British scientists work much more efficiently than their overseas colleagues.
The study, based on a count of the number of scientific papers, their influence in the world of science and the frequency of citations, found that between 1997 and 2001 the UK produced 9.4 per cent of scientific publications, accounting for 12.8 per cent of the most cited papers. For comparison, the figures for Germany are 8.8 and 10.4 percent, Japan - 9.3 and 6.9. Although the United States has gone far ahead in terms of total volume - 35 and 63 percent, the efficiency of American scientists has decreased significantly compared to previous years.
Blueberries protect against senile dementia.
British scientists have found that daily consumption of blueberries or a blueberry milkshake improves concentration and prevents the development of senile dementia. For the research, scientists invited 40 volunteers aged 18 to 30 years. The subjects drank a glass of blueberry milkshake every morning and followed the diet prescribed by doctors. During the day they did several physical exercises, during which the level of concentration was monitored. After a few weeks, the berries were removed from the volunteers’ diet. As a result, the concentration level of the experiment participants after two hours of exercise decreased by 15-20 percent.
Cell phones kill bees.
Cell phone radiation has an extremely negative effect on bees, leading to the collapse of the colony and even to their mass extinction. British experts led by Dr. Daniel Favre came to this conclusion. Scientists conducted an experiment by placing a working mobile phone under the hive. It turned out that bees become very anxious if there is an incoming call on the phone. They gather in a swarm, and after the signal is interrupted, they calm down.
In previous experiments, a phone left near a hive led to the collapse of a bee colony and the mass extinction of bee colonies. Radiation from mobile communications kills 43% of bees, while, for example, pesticides kill only 3% of these insects. The fact is that cellular networks under the GSM protocol operate at frequencies from 800 to 1200 MHz. Bees communicate at these same frequencies and, most importantly, navigate. Cellular networks “clog” the channel, and disoriented bees cannot find the place where they live and feed.
It's good to swear from time to time.
British scientists report that sometimes swearing is good for your health. Moreover, swearing helps most of all those people who usually do not use profanity in their speech. In particular, strong words have a pronounced analgesic effect. The researchers conducted an experiment in which 70 students participated. They had to keep their hands in the ice water for as long as possible. When it became completely unbearable, they were asked to use obscene language. At this time, scientists measured the activity of their brain centers and other body reactions. As it turned out, the participants in the experiments who cursed were able to keep their hands in the water longer than those who could not utter these words. At the same time, the greatest effect was achieved by those who usually rarely use obscene expressions.
A person can become seriously ill in a dream.
Sound, healthy sleep can lead to serious illnesses. British scientists came to this conclusion. In particular, sleeping on your back is fraught with asthma and heart problems, since in this position the body is poorly supplied with oxygen. If a person sleeps on their side, this can lead to early formation of wrinkles. And if the sleeper assumes the “fetal position,” he risks migraines and problems with the cervical spine. The neck will also suffer when sleeping on your stomach. In addition, in this position the sleeper’s hands will go numb, and in certain cases the jaw can also become twisted. Those who like to sleep in an embrace will begin to experience pain in their back, neck, legs, and arms. British scientists did not consider other options for sleeping positions.
Women like gloomy men.
Women are more attracted to men who are moody than men who look happy. Scientists from the University of British Columbia came to this conclusion. A group of thousands of volunteers took part in the study. They were asked to look at photographs of people of the opposite sex and rate them in terms of sexual attractiveness. All photographed people had different facial expressions associated with manifestations of emotions (from a wide smile to eyes lowered to the floor).
Psychologists assessed the first impression of sexual attractiveness of the images. It turned out that women are more attracted to gloomy, concentrated faces. They don't like smiling, cheerful men. Scientists believe that women associate a man’s gloomy appearance with his status, wealth, reliability, and ability to provide for a partner and children. But a smile indicates weakness and defenselessness. In turn, men pay more attention to smiling, joyful women, since representatives of the stronger sex prefer ladies who are easier to make contact and obey.
Old mobile phones should be buried in pots with plants.
A group of British scientists have invented an original way to get rid of old mobile phones. They suggest not throwing them away, but burying them in pots with plants. Elements of a cell phone biochemically decompose over time. Together with the soil, they create favorable conditions for the growth of certain plants. Sunflowers grow best in a pot with a telephone. Scientists have not yet determined whether the phone model affects the growth rate of plants.
There are also scammers and corrupt officials among the ants.
“The first thing you notice when you look at the social structure of ants and bees is how cooperative they are,” says Bill Hughes from the University of Leeds. - However, if you look closely, you will notice that they are also characterized by conflicts and fraud - and in this they are very similar to human society. "We previously thought that ants were an exception, but our genetic analysis showed that their society is rife with corruption, particularly royal corruption." Scientists compared the inequality that is present in anthills with what happens in hives where drones and ordinary bees live. Ants, like bees, have their own carriers of “royal genes”. Dr. Hues and Jacobus Boomsma from the University of Copenhagen found that the daughters of some fathers become “queens” more often than others. In addition, ants carrying special royal genes have the ability to fool their relatives and deprive them of the opportunity to leave offspring.
The oldest joke of man.
Scientists from Great Britain have found the world's oldest joke text. It is noteworthy that this discovery allows us to conclude: humor “below the belt” was no less popular in ancient times than it is today. Researchers from the University of Wolverhampton have determined that the oldest joke was recorded in 1900 BC. It belongs to the Sumerians, who lived in what is now southern Iraq. Rough translation: “This has not happened since time immemorial for a girl to fart while sitting on her husband’s lap.”
Excess alcohol leads to mutations in DNA.
As researchers write in the journal Nature, acetaldehyde, a byproduct of ethanol processing in our bodies, can lead to catastrophic DNA damage. And we would die from the very first glass if the cells did not have a two-step defense system: the first includes enzymes that neutralize acetaldehyde itself, the second is a set of proteins that take on the emergency repair of damaged DNA. Scientists experimented with pregnant mice in which both systems were turned off - in such animals, even a small single dose of alcohol led to the death of the fetus; Moreover, the death of blood stem cells was observed in the adult mice themselves.
Scientists were prompted to check the effect of alcohol on DNA by two groups of information. Firstly, people suffering from Fanconi syndrome, a severe hereditary disease, are extremely sensitive to alcohol. In these patients, the proteins responsible for DNA repair do not work, as a result of which acetaldehyde causes irreversible damage to genes, and this leads to blood diseases and cancer. On the other hand, people with congenital alcohol intolerance are highly susceptible to esophageal cancer, and their acetaldehyde neutralization system does not work. In both cases, the consequences of alcohol intake are expressed in diseases affecting the molecular genetic apparatus of the cell.
Why are drunk men less demanding of beauty?
British scientists sometimes take on the most unexpected topics. This time they wanted to know why drunk men, as popular wisdom says, are less demanding of women’s appearance. The study involved students, the male half of whom had to... get drunk. After such an exciting stage of scientific work, they were asked to evaluate photographs of girls who had already been “sorted” in terms of attractiveness by a fairly large group of sober respondents. It goes without saying that there was no sensation: the assessments of drunken volunteers turned out to be less strict. Having looked closely at the photographs and analyzed the ratings given, scientists came to the conclusion that alcohol takes away people’s ability to adequately assess the symmetry of a face (after all, as you know, the more symmetrical a face is, the more beautiful it seems, based on current standards). Well, the vagueness of the lines always gave everything a certain mystery... That, in fact, is the whole story.
Men and women are awakened by different sounds.
Many mothers, tired of constantly getting up at night and soothing a crying child, begin to hate their husbands, sleeping peacefully next to them and, it seems, completely unable to hear the piercing baby roar. This hatred, as British scientists have proven, is in most cases completely groundless. It turns out that nature has tuned our body to perceive very specific sounds in our sleep, so men really don’t hear the crying of their tiny offspring.
For representatives of the fairer sex, children's sobs are the most annoying sound that can wake up from any, even the deepest sleep. For men, he is not even in the top ten. The most effective “alarm clocks” for the stronger sex are car alarms, the howling of the wind and a fly or mosquito buzzing over the ear.
Enormous sex differences in the perception of sounds during sleep were revealed during an experiment with measurements of the level of brain activity. It was carried out simply: subjects immersed in sleep were “played” various noises, while simultaneously taking an encephalogram. It turned out that any woman reacts sharply to a child’s cry and wakes up, even if she herself is not a mother. At the same time, nature has also provided a compensatory mechanism: representatives of the fair sex fall asleep much faster after sudden night “wake-ups”. But men, awakened by some extraneous sound, then cannot fall asleep for a long time, tossing and turning in bed and suffering.
A portion of hookah is five times more harmful than a cigarette.
A study has shown that a person smoking a hookah inhales as much carbon monoxide as if he were breathing through a car exhaust pipe. That is, one “portion” of hookah can be five times higher than one cigarette in terms of carbon monoxide content.
The best morning exercise is sex.
British scientists, in particular sexologists from Queen's University Belfast, managed to prove that morning sex is healthier than morning exercises. During sex, the arm muscles are strengthened, the chest, pelvis and buttocks are strengthened, as well as blood circulation improves and proper breathing is restored. In addition, sex has a clear preventive effect, in particular, the risk of cardiovascular diseases is significantly reduced; morning sex can fight arthritis and migraines, burn more than three hundred calories at a time, which, in turn, reduces the risk of diabetes.
Tea helps in the fight against nightmares.
In research, experts have found that those who drink more than one cup of tea a day have a 50% reduction in the risk of unpleasant dreams compared to those who practically never drink this drink. Scientists cannot say exactly why this happens. However, they believe that the active chemicals contained in tea, particularly the amino acid tannin, relieve stress and calm negative electrical activity in the brain.
The average temperature on Earth will rise by 4 degrees by 2060.
According to a published report commissioned by the Ministry of Energy and Climate Change, serious temperature changes as a result of global warming will not occur in the distant future, but within the current generations. “An average increase in global temperatures of four degrees would lead to sharper increases in some regions, along with a dramatic change in precipitation. And if greenhouse gas emissions are not reduced soon, our generation will face critical climate change,” said Dr. Richard Betts, head of the Hadley Climate Prediction Center at the British Met Office. At the same time, in the Arctic, as well as in the west and south of the African continent, warming could reach 10 degrees.
The more you run, the better you remember.
Scientists have discovered a new way to improve memory - to do this you need to constantly jog. It turns out that regular jogging has a beneficial effect not only on a person’s psyche and body, but also on his brain. Scientists from the University of Cambridge have shown that jogging stimulates the production of new gray matter cells in the area of the brain responsible for memory, notes Compulenta. Data from experiments by British scientists suggest that just a few days of running lead to the growth of hundreds of thousands of new cells in the area of the brain that is associated with memory.
A way has been found to reduce hangovers.
Scientists have found a way to reduce hangovers after drinking alcohol - to do this, saturate them with oxygen. According to British media, this discovery was made by scientists from Chungnam National University in the South Korean city of Daejeon.
It is known that oxygen is involved in the chemical process in the human body, during which consumed alcohol breaks down into water and carbon dioxide. Scientists took identical portions of the same alcoholic drink, saturated them with oxygen to varying degrees, and gave them to the volunteer participants in the experiment to drink. After some time, the scientists asked the subjects about their feelings and measured the alcohol content in their blood. It turned out that those who had a higher oxygen content in their drink felt better and had less alcohol in their blood.
The leader of the experiment, Professor Kwan Il Kwon, said that after drinking an oxygenated alcoholic drink, the alcohol content in the blood plasma decreases faster than after drinking a drink with a normal oxygen content. The scientists, however, did not specify what kind of drink they used in the experiment and how oxygen affects its taste.
