“The shower should be as short as possible… If it itches, just hold on for two minutes.”

Causes and prevention of itchy skin

When dry, the skin barrier breaks down easily. External substances penetrate and cause itching Causes side effects of drugs such as blood pressure and heart.

The dry season of autumn has arrived. Dry weather adversely affects the skin. Itching is a typical symptom. There is a professor at a medical school who recently published a book on itching. Jinho Jeong, a professor of dermatology at Seoul National University Hospital, who published 'I'm Going Crazy Because It Itches', is the main character

Professor Jung has been researching skin diseases and skin aging for 30 years, especially treating pruritus, senile skin diseases, rheumatic skin diseases, and blistering skin diseases.

Itching due to various causes

Itching occurs when substances that cause itching in the skin stimulate nerves. Typical itch-causing substances are 'histamine', 'IL-31', and 'TSLP'.

Dry skin is the most common cause of making these itch-causing substances. When it dries, the stratum corneum (skin barrier) that protects our body collapses, and irritants from the outside easily penetrate through the gap. As a result, the skin becomes inflamed and the skin becomes itchy.

In addition, itching may occur as a side effect of medications such as blood pressure medications, heart medications, and diabetes medications. Nutritional supplements and healthy functional foods such as vitamins taken daily for health can also cause itching. This is because the ingredients that enter the body can cause an immune response or an inflammatory response, which can cause itching. Therefore, if it is not absolutely necessary, it is also a way to stop taking such foods for a while.

In addition, food or skin diseases can cause itching, and it can also occur when there are medical conditions such as liver disease, kidney disease, thyroid disease, diabetes, etc. Professor Jung said, “Itching can occur even when there is a lot of stress, such as emotional anxiety, psychological anxiety, and unexpected diseases that we did not even think about. said

If itching occurs, be patient for once.

When itching occurs, it is best to hold it without scratching for the first 1-2 minutes. The reason why the skin feels itchy is that the sensory nerves in the area are activated and transmit the itch signal to the brain.

Professor Jung said, “When the itch stimulus comes once, the biochemical reactions that occur at the sensory nerve endings in the skin only last for 1 to 2 minutes at most and disappear soon. It doesn't itch," he explained. Massage with ice when itchy is also helpful in improving symptoms as it reduces inflammation.

He said, “Don’t think of itching as a painful feeling, and try to change your mind for a moment. said.

Prevention of itchiness, this is a must

There are certain things that you must practice in your daily life to prevent itching. Above all, using a mildly acidic cleanser instead of solid soap when washing your body helps prevent itching. Since the normal acidity of the skin is weakly acidic, the use of alkaline ingredients may break down the skin barrier.

It is best to keep the shower as short as possible. This is because the contact time with soap and damage to the skin barrier can be minimized. It is recommended to apply a moisturizer at least twice a day and choose a moisturizer that contains lipids and sugars such as cholesterol, ceramide, and fatty acids.

Keep indoor humidity above 50%. It is helpful to keep the room temperature at 20-22 degrees. And keeping your mind calm with meditation, reflection, and positive thoughts can also help prevent itchiness. Professor Jeong said, "If you receive treatment from a specialist for medical or skin diseases that are aggravating factors for itching, and keep practicing to prevent itching, you can prevent itching from recurring."

Why doesn't monkeypox spread

noreply@blogger.com (Unknown) — Wed, 31 Aug 2022 06:10:00 +0000

Why doesn't monkeypox spread as much as Corona?

Although both Corona 19 and monkey smallpox have been declared international health emergencies, monkey smallpox is unlikely to spread explosively, so there is little mutation.

Until the last column, we looked at the viral characteristics of COVID-19, immunity, vaccine, treatment, quarantine, history, and ecosystem aspects. From this column, we will compare the newly emerged monkey pox and Corona 19 and look at it from various perspectives. Except for the fact that they are novel viruses, these two exist at polar opposites in the virus kingdom. Through this comparison, it will be possible to broaden the understanding of the factors that determine the pattern of pandemic development of various viruses.

On July 23, just over two years after COVID-19, the World Health Organization (WHO) declared monkeypox as an international health emergency. Does this mean it will have as devastating consequences as COVID-19? In conclusion, it is unlikely that it will spread explosively (although it tends to spread). However, it is difficult for the general public to determine whether the declaration of a monkeypox emergency is a big problem like COVID-19 or a precautionary warning.

SARS, novel flu, MERS, Corona 19, Ebola, monkey pox, etc. The danger warning of the new virus in the 21st century continues to fall into controversy. If we look into the decision process of the monkeypox emergency declaration, we can guess the reason why the spark of the controversy does not go away. After it was confirmed as a new virus earlier this year, consultations could not be reached at two emergency meetings of experts, and the secretary-general then ex officio declared a state of emergency. This shows that the level of risk assessment varies among experts. It cannot be easy to change these various evaluations into one voice.

Pandemic risk is probability. It can have an infinite number of values between 0, which will never happen, and 1, which will definitely happen. And each expert evaluates his or her own unique risk probabilities. However, there are only two values: whether to declare a pandemic or not. That is, the danger has an analog value, and the danger alarm has a digital value. It is natural that information loss occurs when analog information is converted to digital. In the era of frequent outbreaks of new viruses, a rational judgment standard is required for each individual, going beyond the dichotomous declaration of professional organizations. This is because the risk of a particular virus varies from person to person, situation, and environment.

Without self-judgment, we are easily swayed by misinformation, and public confusion causes an infodemic. Information derived from misinformation spreads rapidly like a pandemic. Infodemic, which spreads as quickly and strongly as it is irritating, exposes individuals to risk or fatigue, and raises social distrust of quarantine and increases costs. Reasonable value judgment is based on sound judgment. If it is a vaccine to contain the spread of the virus, it is the right knowledge to contain the infodemic.

Why vaccinia also works for monkey pox

Let's start with the story of smallpox instead of the unfamiliar monkeypox. Smallpox, infamous enough to kill one in three infected people, has plagued mankind enough to change the course of history. It is also recorded in history as the first and last virus to be wiped out by mankind through the power of science. Just as COVID-19, SARS, and MERS are coronavirus cousins, monkeypox and smallpox belong to the same poxvirus. Mammals such as cows, goats, and monkeys each have their own smallpox virus, and the human smallpox virus was smallpox.

The smallpox virus was wiped out by a vaccine made from vaccinia, a bovine smallpox. The vaccinia virus that infects humans cannot reproduce properly because of the interspecies barrier. It stimulates immunity, but only mild symptoms, and an infected person does not transmit vaccinia again to others. Importantly, antibodies to vaccinia virus also cross-react with smallpox virus antigens. This means that the antigenic sites of the two heterologous viruses are identical.

Vaccinia is a live, attenuated vaccine that exists in nature, and shows about 85% protection against monkeypox. This means that people who have previously been vaccinated against smallpox are somewhat protected against monkeypox. These facts show that smallpox viruses with DNA genes are less likely to mutate. The double-helical structure of DNA is specialized for the safe storage of vital information, and the occurrence of mutations during replication is low. This characteristic is disadvantageous as a gene of the virus because it hinders the securing of genetic diversity. So, during nearly 200 years of using the vaccine Jenner first vaccinated to the gardener's son, no resistance mutations have emerged. In contrast, a vaccine against COVID-19 that has an RNA gene has developed resistance in just a few months.

How smallpox could be eradicated

The Jenner vaccine continued to be vaccinated for over 150 years, but smallpox outbreaks were intermittent among unvaccinated children. This shows that even if there is a vaccine, application is another matter. Awareness of the common problem of mankind was formed during two world wars in succession. This led to the creation of several international organizations.

Among them, the World Health Organization (WHO), which was full of young enthusiasm, had a strong will to jointly respond to the virus threat. In order to eradicate smallpox, which still plagues people despite good vaccines, he concluded that all children in the world should be vaccinated and began to act. In 1966, the World Health Organization's smallpox eradication campaign began. Great powers provided funds, pharmaceutical companies provided cheap vaccines, and volunteers went to the jungle and desert to vaccinate children.

The World Health Organization officially declared the smallpox virus extinct in May 1980. This is probably the COVID-19 news we all want. The history of smallpox has shown that even with the best vaccine, a joint human response is important to properly apply it. However, as time passed, the perception that the new virus was a common human problem has faded.

This COVID-19 pandemic has revealed just how vulnerable vaccine nationalism is to virus mutation. While developed countries encouraged booster shots, in most countries, even the primary vaccination was not done well for a long time. The genetic diversity of Corona 19 has exploded and new mutations have continued to appear in countries that are in the dead of quarantine. Vaccine-resistant mutations have returned as a boomerang in developed countries.

In this column, we investigated the history of smallpox by introducing the monkey pox virus. In the future, we will compare monkeypox with Corona 19 in terms of genes, infection route, and transmission speed. It is hoped that this will give us a clearer understanding of what caused COVID-19 to become a serious pandemic.

Regular physical activity lowers risk of severe COVID-19 and death

People who engage in regular physical activity have a lower risk of death, seriousness, and hospitalization even if they contract COVID-19, a study found.

According to the medical community on the 24th, a research team from the University of Valencia in Spain analyzed the data of 1,853,160 people included in 16 studies to determine the relationship between physical activity and the risk of severe COVID-19, and recently published the results of the study in the British Journal of Sports Medicine.

Research shows that people who engage in regular physical activity have a lower risk of contracting COVID-19 than those who are inactive.

89% of cases of COVID-19 infection, 64% of hospitalizations, 66% of severe cases, and 57% of deaths were found to be low.

"This study appears to be associated with a lower likelihood of regular COVID-19 negative symptoms," the researchers said. It can help develop guidelines for the level of physical activity that is present.”

James Webb's discovery of carbon dioxide in exoplanet atmospheres

The James Webb Space Telescope, expanding the horizons of astronomy, has now discovered carbon dioxide in the atmosphere of an exoplanet 700 light-years from Earth.

Carbon dioxide, a representative greenhouse gas, is a substance that is released into the atmosphere in increasing amounts by human activities as part of the global carbon cycle. Scientists see the presence of carbon dioxide in the planet's atmosphere as an important step in finding chemical markers for extraterrestrial life.

Astronomers have previously hinted at the presence of carbon dioxide in the atmosphere of exoplanets through observation data from the Spitzer Space Telescope, an infrared telescope such as James Webb, but have not been able to confirm it with certainty. James Webb solved this problem at once with excellent infrared detection.

The National Aeronautics and Space Administration (NASA) announced on the 25th that James Webb had detected carbon dioxide in the atmosphere of the gas giant WASP-39b in the constellation Virgo. Discovered in 2011, this planet is receiving a lot of attention because it is estimated that it contains a significant amount of water. The analysis results were published in the pre-published thesis collection 'Archive' on the 24th, and will soon be published in the international academic journal 'Nature'.

Analysis of the wavelength of light as a planet passes in front of a star

WASP-39b is 1.3 times the size of Jupiter, but has a mass about a quarter that of Jupiter, similar to that of Saturn. In other words, it is a celestial body that has inflated like a balloon. This is due to the high temperature of 900 degrees. About 800 million kilometers from the Sun, Jupiter is very cold, but WASP-39b is very close to the star. It orbits a solar-class star about once every four days, at only about one eighth of the distance from the Sun to Mercury.

As a planet passes through a star, some of the starlight is blocked by the planet and some is transmitted to us by striking particles in the planet's atmosphere. Because the color combination of the light absorbed by each element is different, by analyzing the wavelength of the light passing through the atmosphere, it is possible to find out the elements of the planet's atmosphere. In the meantime, NASA has found water vapor, sodium and potassium in the planet's atmosphere.

James Webb's near-infrared spectrometer reads three types of wavelengths as a planet passes in front of a star, with sensing power that can detect hundreds of colors at once. The wavelengths sent by the spectrometer ranged from 3.0 to 5.5 micrometers. As a result of the analysis, carbon dioxide characteristics were clearly shown at an average wavelength of 4.3 micrometers (4.1 to 4.6). This is the first clear evidence of carbon dioxide in observational history, NASA said.

"Wavelengths in this range are important for measuring the presence of water, methane, and carbon dioxide," NASA said.

It is also essential for tracking planetary origins and evolutionary processes.

The discovery is significant in that it shows that James Webb can detect carbon dioxide in the atmospheres of smaller rocky planets in the future, NASA said.

Carbon dioxide, which is closely related to life activities on Earth, is a substance that serves as an indicator of metalicity and is important for tracking the origin and evolution of planets. Heavy element content refers to the proportion of elements heavier than helium. Therefore, the content of heavy elements in a celestial body is one of the measures of judging the age of the celestial body.

This observation was conducted for 8 hours on July 10. The time the planet passed through the star was 2.8 hours.

“Aww!” when raising the arm. If it comes out loud, get a 50 shoulder test at the hospital

Frozen shoulder is named as occurring most often in people in their 50s. The official name of the frozen shoulder is 'adhesive capsulitis' or 'frozen dog', meaning that the shoulder is stiff as if it were frozen.

Frozen shoulder occurs mainly in people in their 50s to 70s, and the distribution range is quite wide from 20s to 80s in terms of the entire age group. According to the statistics on diseases of public interest in 2021, out of about 875,000 patients with frozen shoulders, those in their 50s accounted for the most at 33.7%. Those in their 60s were followed by 29.7%, those in their 40s with 15.5%, those in their 70s with 13.8%, and those in their 80s with 4.7%. Although there are not many young patients, they accounted for 2.1% in their 30s and 0.5% in their 20s.

Frozen shoulder is a disease in which the joint capsule surrounding the shoulder joint becomes inflamed without any special trauma. Severe pain and limited activity. The cause of the disease is not clear. However, aging or inflammation caused by rupture or hardening of the muscles of the shoulder joint can lead to a frozen shoulder. It is known that patients with systemic diseases such as diabetes are more likely to develop frozen shoulder.

Frozen shoulder is often discovered by patients experiencing shoulder pain or discomfort in daily life. Pain is felt when raising your hands or facing your back, such as brushing your hair, showering, carrying your luggage, or taking your wallet out of your back pocket. Also, if the arm does not rise well, you may suspect a frozen shoulder.

Since the symptoms of a frozen shoulder can worsen over time, it is better to visit a hospital early and get an accurate diagnosis. Professor Lee Kang-woo of the Department of Rehabilitation Medicine at Myongji Hospital said, “If the frozen shoulder is detected early, the symptoms can be improved without surgery, only with physical therapy and exercise therapy.

In the initial stage of the frozen shoulder, physical therapy, exercise therapy, and injection therapy are mainly used. Physical therapy includes electrical nerve stimulation therapy and ultrasound therapy. Exercise therapy involves stretching and strengthening exercises. The important thing is that the patient must be active according to the order of the professional therapist so that the effect is fast and there are few side effects. If pain and discomfort persist even after conservative treatment for 6 months to 1 year, surgery and rehabilitation exercises are performed in parallel.

Most of the frozen shoulder gets better with treatment, but 10-20% of patients experience recurrence or a frozen shoulder develops on the opposite arm. Therefore, it is important that you continue to stretch your shoulders and exercise even after treatment.

In order to prevent frozen shoulder, it is good to perform bare-handed gymnastics using the arms regularly every day. Even in this case, you must learn gymnastics from a professional therapist. If there is pain, it is better to choose the most comfortable cold or hot compress at home and to take the position with the least pain.

“It’s 86 degrees below zero, I’m still alive”… Mars helicopter flies after two months

Humanity's first extraterrestrial powered airplane made its 30th flight from Mars.

The National Aeronautics and Space Administration (NASA) announced that the small Helicopter on Mars had flew again on the 20th, two months after completing its 29th flight. The 29th flight took place on 11 June.

NASA's Jet Propulsion Lab posted on Twitter an in-flight photo of Ingnuity's one leg and the surface of Mars, saying, "Breaking the two-month hiatus and confirming that the helicopter is still alive through a short flight over the weekend and dust from the solar panels. He was able to get rid of it.

2 meters in 33 seconds... not an easy flight

NASA designed this flight to fly 2 meters in 33 seconds. But I didn't expect it to be easy.

Robot exploration is an example where persistence is active, because the delta area of the crater was winter and the solar panel was more dusty and the battery could not be properly charged. According to NASA, temperatures in the region now drop to minus 86 degrees at night. Prior to the flight, NASA tested the wing's rotational force for a few seconds each on August 6 and 15.

As the 100-day winter gradually passes, the state of charge of Incinuity has improved, and Nasa expects that it will be able to go out to reconnaissance in the delta within a few months. To this end, it plans to upgrade its flight software in September.

Total flight distance 7km in 1 year and 4 months

Since its first flight on April 19, last year, Injinuity, weighing 1.8 kg, has gone beyond its original goal of five test flights, and has been conducting reconnaissance flights to fulfill the mission of the robot exploration vehicle Perseverance.

The flight altitude was 5 to 12 meters, the flight speed averaged 5.5 meters per second, and the flight distance was 100 to 625 meters. So far, the total flight time is 55.4 minutes and the flight distance is 7.08 km. Now, beyond the simple test flight phase, it is conducting a pre-field mission to aid persistence in its journey.

Child doing ○○ before going to bed, sleep quality deteriorates

Children who watch TV before bed are more likely to develop problems such as sleep disturbance and attention deficit, a study has found.

A research team at New York University in the United States conducted a study to find out how the habit of watching TV before going to bed affects infants (0-2 years old). The participation was conducted with 403 households living in New York and Pittsburgh. The survey was conducted twice in total, when the children of each family were 18 months old and 2 years old (24 months old).

The first survey, conducted when the child was around 18 months of age, evaluated 'how much TV is shown before going to bed', 'how many hours the child sleeps at night', and 'the quality of the child's sleep'. At the age of two, they asked about 'the child's attention problem' and 'aggressive behavior'.

As a result of the analysis, 52% of respondents said that they watched TV to their children before bedtime. Children who watched TV before bed had less than average total sleep time by the age of two. They also experienced sleep disturbances more frequently than children who did not watch TV. As the quality of sleep deteriorated, attention deficit and aggressive behavior were also observed, the researchers explained.

Miller, assistant professor of population health at New York University's Grossman University, said, "The study found that poor quality sleep can lead to problem behaviors. It led to problematic behavior.” “Parents should help their children form good sleep habits,” he said.

“Redundancy of sleep rituals. You have to frame a good habits.”

If a child's sleep disturbance persists for a long time, it can negatively affect brain development and growth and development processes such as height. According to one study, children who had irregular sleeping habits until the age of three had slower development of learning skills, such as reading, math, and spatial perception skills. Experts advised that it is recommended to repeat sleep rituals, such as giving a massage or singing a lullaby, before going to bed from 6 weeks of age.

How to select a business PC in the era of hybrid work

It's too early to give up saying "I can't do it..."! How to choose a business PC that troubled information systems should know

"Telework (remote work)", which has spread rapidly in response to the new coronavirus infection, is progressing one step further to "hybrid work" that does not choose where to work. How should I choose a PC for business in such an era? Before considering the model from the specific functions, shouldn't we consider the deployment method?

　More than two years have passed since the response to the new coronavirus infection continued. Recently, vaccination has progressed and the rate of severe cases has decreased, but the situation is still unpredictable.

　Even in Japan, the introduction of telework (remote work) has been promoted as part of work style reform, mainly by major companies. The corona crisis has accelerated this movement, and it seems that the telework system is being developed as part of the BCP (Business Continuity Plan), including during disasters. Taking a step further from there, hybrid work that does not choose where to work has become one of the keywords these days.

　This kind of movement is not unrelated to small and medium-sized enterprises and SOHOs (small/personal offices). Depending on the industry, telework and hybrid work have the advantage of not choosing a place to work, which is advantageous in terms of securing human resources. You should take some countermeasures before saying, "Our company (office) is small."

Nonetheless, regardless of the size of the company or business, the selection of a business PC assuming hybrid work is one of the major challenges. First of all, even if you can imagine that "equipment for web (video) conferencing is necessary", there may be some people who do not know (cannot think of) other points to emphasize.

　Therefore, we will explain how to choose a business PC in the hybrid work era in three parts. In the first installment , let's consider the deployment (deployment and expansion) of PCs to employees, which we want to be aware of because of "hybrid"

How can I choose a PC suitable for "hybrid work" that can work anywhere?

The first thing to think about is "kitting" rather than "corresponding to web conferencing"

As mentioned above, when considering a PC for hybrid work, many people may think that "equipment for web conferencing is necessary". However, what should be imagined in the early stages is the method of "kitting" and "distribution (delivery)" of PCs . Web conferencing is a story "after" the distribution of PCs, so there is no big problem if you put it off and consider it later.

what do you do in kitting?

　Unlike private PCs used by individuals, PCs used for business require "installation of necessary applications" and "policy settings" in line with the business and security policies of the company or organization. This is the so-called "kitting".

Kitting, which puts too much strain on the information system, carries a big risk

　The information system "goes to work", makes the necessary settings on the PC, and delivers it to the user by courier service--even with this, "hybrid work" can be realized. However, if we go back to the “origin” of hybrid work, which is to work anywhere, there are some problems with this method. Of course, the information system has to come to work, but if for some reason the information system can't come to work, the problem of not being able to do kitting and delivery work can't be solved.

　If kitting or delivery stops, the allocation of new PCs will be delayed, and employees' work may be disrupted. In order to demonstrate the "true value" of hybrid work, we should first consider ways to reduce the burden on information systems involved in kitting and distributing PCs .

　In order to improve the continuity of the business and the efficiency of future operations, I would like to keep this in mind.

WiFi 6: Get your kicks with WiFi 6!

The latest WLAN generation is called WLAN 6 or Wi-Fi 6. This standard is faster, more powerful and achieves a greater range. In addition, WLAN 6 scores in terms of energy efficiency and security. We'll show you how to get the most out of your new WiFi 6 network.

What is WiFi 6?

WiFi 6 is the latest generation of WiFi technology. The terms Wi-Fi 6 and 802.11ax are also used as synonyms for the network protocol. The latter is mainly found in technical language usage. The history of WLAN (Wireless Local Area Network) begins in the late 1990s. The transmission standard developed from the no longer used 802.11 to 802.11n (WLAN 4) to the now new 802.11ax (WLAN 6).

What are the advantages of WiFi 6?

As can be seen from the infographic, a WLAN 6 router provides you with a significantly higher data throughput. With WLAN 6 you surf up to 2.5 times as fast as with WLAN 5. However, it should be noted that these are theoretical gross values. In practice, a maximum of 50 percent of the theoretical transmission speed is realistic, but the achievable values depend on the respective Internet connection. WLAN 6 offers particular advantages when many different end devices are connected to your network. Possible applications are households with several simultaneous users , but also smart home systems with several wireless cameras, motion detectors and the like. Or offices and student flat shareswho like to celebrate extensive streaming evenings in 4K or 8K. In addition to the greater range and speed, WLAN 6 also impresses with improved energy efficiency. So you not only save nerves when downloading and uploading, but you can also reduce power consumption. Currently, the energy saving effect mainly relates to IOT applications and autonomous devices. But the increasing networking of private households can be done in the future through the use of WLAN 6-capable receivers. WPA3 ( Wi-Fi Protected Access 3) also increases WLAN security.

Five places you should never put a wireless router

You won't believe what can slow down even a good wireless router. We reveal which locations you should avoid.

Videos stutter, music stutters, transferring files takes forever - is your wireless home network so slow that not only surfing the Internet is no fun? Often the problem is not due to the technology in the router or even to the Internet connection to the outside.

The Telekom technicians who are called for help often find that the WLAN router is simply in an unfavorable position, because there are a few places where the wireless connection is disrupted by common household items.

To prevent this from happening to you, here are the five worst places you should never put a wireless router:

1. In a metal cabinet or shelf

Any metallic casing of the router drastically shields its antennas and thereby dampens the propagation of the radio signal. If you're annoyed by slow Wi-Fi - here's why!

2. On the floor behind the PC

Positioned in this way, the router is not visible – but neither is your wireless network. The pc acts as a shield preventing the radio waves from propagating - much like the metal shelf above. The effect: Other devices that are further away have poor reception.

3. In the basement

Routers are usually optimized for horizontal illumination of the premises. They emit relatively little radio power upwards. In addition, the ceiling acts as a radio brake. The reception is already bad on the ground floor.

4. In a remote corner of the room

As already mentioned, the antennas installed in routers usually transmit horizontally to all sides evenly. By positioning it in the far corner of a remote room, you may be providing optimal service to the adjacent street, but not your home.

5. Behind large leafy plants

Large leaves contain a lot of water. And this is exactly what prevents the radio waves emitted by the router from spreading. The result: the range and transmission speed decrease.

An optimal parking space is therefore as free-standing as possible without metal in the area on the floor where the connection is most needed.

By the way: plasterboard walls – often referred to colloquially as “plasterwall” – also dampen the WiFi signals. If such walls are used in the house, it can also affect the connection.

Tired Brain

noreply@blogger.com (Unknown) — Fri, 19 Aug 2022 17:51:00 +0000

The more tired the brain, the more impulsive choices... Important decisions, avoid at night

“Thinking is the most difficult and tiring of all labors. So many people avoid thinking.”

These are the words of American author Wallis Wattles (1860-1911) listed in an online collection of quotes. In fact, if you sit down and concentrate on something for a few hours, you will feel a lot of fatigue.

Although it weighs 2% of the body, it uses 20% of the energy for a long period of time because the brain was abused for a long time.

Scientists at the Paris Brain Institute (PBI) in France have recently discovered a metabolic mechanism in the brain that could explain this.

Finding the identity of substances that accumulate in the brain as a result of long-term mental labor. The research team reported in the international scientific journal 'Current Biology' that glutamate (glutamic acid) accumulates in the prefrontal cortex in the front of the brain when you concentrate on work for a long time, and this appears to cause fatigue. Researchers found that when glutamate accumulates in large amounts, it becomes difficult to concentrate and work or make decisions.

When a lot of glutamate builds up in the prefrontal cortex, it becomes difficult to concentrate and work or make decisions.

What is glutamate?

To find the source of mental fatigue, the research team used magnetic resonance spectroscopy (MRS) technology to measure chemicals secreted in the metabolic process of living tissues.

The researchers used the device to see what happens in the lateral prefrontal cortex, which is responsible for high-level mental tasks such as making decisions and making plans.

The researchers first recruited 40 experimental participants and divided them into a group dealing with a difficult task and a group dealing with an easy task.

Then, each of them was given a task and asked them to lie down on a brain scanner and perform the task. For example, a different number was displayed on the screen at 1.6-second intervals and asked to say whether the currently displayed character is the same as the previous one. 26 people were given a difficult problem judging whether they match the three previously shown characters, and 14 people were given an easier problem.

Analysis of the data recorded by the scanner revealed that the brain secreted eight chemicals, including glutamate, a signaling substance between nerve cells, while the participants were solving problems.

The electrical signal from the nerve cell itself cannot cross the synapse that connects the nerve cell. Instead, compounds such as glutamate are secreted, which transmit signals to other neurons. Glutamate is a key substance responsible for more than 90% of information transfer between neurons. The small sacs (vesicles) of the synapse, which are the junctions between neurons, contain 8,000 glutamate molecules per sac.

After the six-hour memory test, the glutamate levels of the participants who solved the high-difficulty problem increased significantly more than when the experiment began. Another indicator of fatigue, pupil dilatation, was also observed.

The glutamate levels of the participants who solved the easy problem were almost the same as at the beginning. They also complained of fatigue, but pupil dilation did not occur. Except for glutamate, seven other chemicals remained unchanged.

Location of primary visual cortex (V1) and lateral prefrontal cortex (LPFC) (A) and changes in glutamate levels in both cerebral cortex (B). Looking at the picture of B, it can be seen that glutamate was greatly increased in the lateral prefrontal cortex when performing a difficult task (orange). Current Biology

More impulsive decisions are the brain's defense strategy

The researchers also investigated whether mental fatigue affects decision-making. When people are mentally exhausted, instead of persevering, they seek immediate pleasure or act impulsively.

The researchers asked participants to choose whether they would like to receive a small amount of money right away or more money later.

Participants who felt more fatigued from solving difficult problems, and thus more glutamate, were more likely to receive a small reward immediately. The group who solved the hard problem had an 8% increase in glutamate overall and 10% more impulsive choices.

Glutamate is a key excitatory neurotransmitter in the central nervous system and plays an important role in memory. In order for the cortex to function smoothly, it must maintain a proper balance with the inhibitory neurotransmitter GABA. However, when glutamate is too much, it acts toxic to nerve cells (neurons) and causes the neurons to die. This disrupts the balance of neurotransmitters and reduces the ability to transmit information.

The researchers reasoned that making more impulsive choices in people tired of solving difficult problems may be a defense mechanism in the brain to prevent excessive build-up of glutamate, which can harm neurons. Applying the results of this study, it is best to avoid the night as much as possible if you have to make an important decision. After a full day of mental labor, you are likely to make impulsive decisions.

Glutamate is cleared from synapses while you sleep, which may be why you feel refreshed the next morning.

An indicator of how hard your brain worked

"This study shows that cognitive tasks lead to 'accumulation of harmful substances' (increased glutamate) in the brain," said Professor Matthias Pécilion of the University of Pittier-Salpetrière, a member of the research team in a press release. "It's a signal to stop what you're doing to preserve normal functioning." He added that glutamate is cleared from synapses during sleep, and that may be why you feel refreshed the next morning.

Building a 180-meter-high dam on the Hwanghe River with 3D printing technology and AI

The largest 3D printing architectural project ever started.

China is building the Yangqi Dam for hydroelectric power generation upstream of the Huanghe River in the Tibetan Plateau using 3D printing technology and artificial intelligence. did. The construction period is two years, with completion expected in 2024.

According to the newspaper, the dam is built using a 3D printing method in which construction equipment such as bulldozers, trucks, excavators and rollers are operated with artificial intelligence technology to build layer by layer.

Construction, which was approved by the National Development and Reform Commission in December last year, proceeds through approximately six steps. First, the artificial intelligence system, acting as the commander of the construction, analyzes the computer model of the dam, and based on this, assigns tasks to the robot machines mobilized for the construction of the dam.

The robot equipment assigned to the task picks up the necessary materials from the stockpile and loads it into the autonomous truck. The truck carries the material to the right place along the optimal path calculated by artificial intelligence, and the robot bulldozer receives it and stacks it layer by layer. Then, an automatic rolling press machine equipped with a sensor presses the surface to harden it.

When the stacking is completed, the sensor sends information about how far the construction has progressed to the central system, and artificial intelligence analyzes and evaluates it.

This method of using artificial intelligence to operate several automatic machines as a system does not use a 3D printer, but can be evaluated as a new 3D printing technology in that it is stacked layer by layer.

Freed from arduous and dangerous dam construction

This project is the product of ten years of research and development by Tsinghua University Professor Liu Tianyun, lead author of the thesis.

Professor Ryu argued in his thesis, “After years of development and testing, 3D printing technology for large-scale infrastructure construction is now mature enough. When robots and artificial intelligence systems are used, there is not only no risk of safety accidents, but also the advantage of being able to proceed with construction without long periods of time or rest periods. Dam construction has a high risk of accidents because the terrain is rough and the dam construction has to work in a rough environment such as large rocks and deep rivers.

Professor Ryu also added, "It can prevent mistakes that workers can make, such as placing materials in the wrong place or not stacking them upright."

Loading and transporting materials and building dams are done by automatic machines, but preparing building materials such as stones and sand is still done by human hands.

The largest structure built with 3D printing technology

The planned height of the dam is 180 meters. It is much higher than Soyanggang Dam (123m in height), which has the largest storage capacity in Korea. When the dam is completed, the hydroelectric power station will be the world's tallest structure built using 3D printing technology.

This dam construction is actually an extension, not a new construction. A hydroelectric power plant with a power generation capacity of 1200 megawatts has already been in operation here since 2016.

After completion, the Yangchu hydroelectric power plant will supply about 5 billion kwh of electricity annually to Henan Province, which has a population of 100 million. Researchers at Tsinghua University said in their paper, “Operating the Yangqi Dam has the effect of reducing annual coal consumption by 1.5 million tons and greenhouse gas emissions by 4.4 million tons.”

If the dam project is successful, the research team predicted that the 3D printing method through artificial intelligence-robot cooperation could be applied to other construction projects such as roads.

From 1 trillion to 100 views after 25 years of becoming the strongest supercom ... 1 million-fold performance improvement Expected to play a

major role in climate model, new energy and drug development

2.5 operations per second is the best

World most powerful Supercomputer 'Frontier'

100 rounds per second.

The era of supercomputers in which the number of operations per second reached the exa (100 magnification = 1,000,000,000,000,000,000 = 10^18) level has begun.

It took 11 years to transition from Terra to Peta and 14 years to transition from Peta to Exa since the first Terra (1 trillion) class supercom appeared in 1997 and the Peta (1000 trillion) class supercom was introduced in 2008. That's a million-fold improvement in skills in 25 years.

Supercomputers with outstanding computational power that cannot be surpassed by ordinary computers are another silent battlefield in the digital world.

Supercomputers were originally created for military purposes, such as cracking code, but have now become indispensable tools for solving complex problems faced by science and industrial society, from product design to vaccine development, climate change modeling, and space simulation.

Since the 2000s, Japan and China have joined the supercomputer competition structure, in which the United States has an overwhelming advantage, and the three countries have been up and down for the position of the strongest supercomputer.

Since 2013, China has introduced Tianhe 2A and Sunway one after another, overtaking the United States until 2017 to occupy the supercomputer throne for four years. Currently, 173 of the world's top 500 supercomputers are from China, far more than the 126 from the United States. Although the number of supercomputers is small, Japan is also one of the world's most powerful countries in this field. Japan's supercomputer Fugaku surpassed IBM's Summit in June 2020 to take first place.

Computing power more than doubled compared to the previous No. 1

Recently, the United States took back the throne for the first time in two years by raising the performance of supercoms by one level.

At the '2022 International Supercomputing Conference' held in Hamburg, Germany at the end of May, Supercomputer Frontier of the U.S. Department of Energy's Oak Ridge National Laboratory was selected as the world's fastest supercomputer, beating out Japan's Fugaku. In particular, for the first time ever, Frontier demonstrated exascale computing power in an official performance evaluation.

In this evaluation, the number of operations per second of the frontier measured in this evaluation is 1.102 exaflops (1 exa = about 100). Supercom evaluates performance in terms of 'FLOPS', which refers to the number of floating-point operations that can be processed per second. 1.102 exaflops means 110 to 2,000 trillion calculations per second. Assuming that one person solves one multiplication problem per second, it is equivalent to the number of problems that 7.9 billion people in the world can solve in four and a half years. One supercomputer can finish the math problem book that everyone on Earth has to work on for four and a half years in one second.

This is more than twice as fast as the previous champion, Fugaku. Fugaku showed an actual measurement performance of 442 petaflops (44 around 2,000 trillion times, 1 peta = 1,000 trillion) in an evaluation in November last year. The performance of a single frontier takes up a quarter of the total computing power of the Top 500 supercomputers.

Supercomputers are also useful for running the latest artificial intelligence algorithms. In the case of Frontier, it recorded a maximum of 6.88 exaflops in calculation speed based on the type of computing used in machine learning. Japan's Fugaku also shows Exa-level performance in this sector.

Official operation early next year... No. 1 in energy efficiency

Oak Ridge National Laboratory is currently working to verify the performance of the Frontier. When this process is completed, Frontier is expected to enter full operation in early 2023.

Frontier, which gave America the title of the strongest supercomputer again, was made by Hewlett-Packard Enterprises and consists of a total of 74 cabinets. It contains 9,400 CPUs and 37,000 GPUs manufactured by AMD. The total number of cores is 8.73 million, which is 1 million times that of a general laptop PC (5 to 9 cores). Each cabinet alone weighs 8,000 pounds (3.6 tons).

Thomas Zacharia, director of the Oak Ridge Research Institute, said, “The production of Frontier has been difficult due to COVID-19, but in the future, Frontier will be able to play a major role in studying the impact of COVID-19 and helping the transition to a clean energy source.”

The scientific community expects exascale supercomputers to show new achievements in science fields that require very complex calculations. The institute plans to use Frontier to simulate the birth and explosion of stars, analyze the properties of the world of particles smaller than atoms, search for new energy sources such as nuclear fusion, and diagnose and predict diseases using artificial intelligence.

Frontier took first place in the Green 500, which evaluates the energy efficiency of computers, with 62.68 gigaflops per watt.

[Books & Thoughts] Are all these things 'real labor'?

Corona 19, which has 'locked down' the world for over two years, has made people doubt about conventional wisdom and practices. Among them, the question of labor deserves the first place. This is because, as telecommuting and teleworking have spread widely in general workplaces, many people are starting to tilt their heads towards the way they used to work. Do I have to go to work and keep my seat to work? Did things go well without all kinds of meetings and meetings? New perspectives lead to more fundamental questions. What is labor and productivity? How is our labor measured?

Danish anthropologist, consultant, philosopher and critic, the two authors of this book (published locally before Corona) declare that much of work in modern society is an illusion. Everyone is busy and working for a long time, but if you know it, it means that there is a lot of 'fake labor' which is a meaningless waste of time. Various interviews and research cases are presented as the basis for this. Labor, which was revered as a source of value creation in classical political economy, has now been pointed out as an activity that is close to a mirage mixed with all kinds of absurdity.

Is my money in the bank safe?

Picture of some currencies

Everyone has their cherished money in the bank. Now let me ask you a creepy question. Is my money in the bank safe?

A bank is a financial institution that earns money by lending money deposited by depositors. So, banks lend most of their deposits to people or companies in need of money. With interest earned on the loan, the bank pays deposit interest to depositors.

There is always a risk of not getting your money back with a loan, as there is no guarantee that all borrowers who borrow money will pay it back. Banks are also at risk if there are a lot of places where they can't pay off their loans. The worst-case scenario could be that you don't have enough money in your safe to return your deposits and interest.

Of course, these days, such a terrible situation seldom happens because banks are strict in managing their loans. However, it is a big deal if people become anxious because of the possibility of one-on-one occurrences and hesitate to deposit in a bank.

A meteorite from Mars 200 million kilometers away... Found the hometown of 'Black Beauty'

A Martian meteorite 'Black Beauty' was discovered in the Sahara Desert in Morocco in 2011. Wikimedia Common

Mars, which is the most similar to Earth in the solar system, orbits the Sun at a distance of 56 million kilometers from Earth and 400 million kilometers from Earth. Millions of years ago, a giant asteroid struck Mars, an average of 225 million kilometers from Earth. The impact threw chunks of rock on Mars' surface into space. One of them flew hundreds of millions of kilometers and landed in the Western Sahara Desert in Morocco, northwest of the African continent. The rock, which was buried in desert sand and appeared in the world in 2011, was passed on to the United States through the hands of an American meteorite collector.

Earthlings gave the rock the nickname 'Black Beauty', along with the official name 'NWA 7034' (Northwest Africa 7034) after the area where it was discovered. The shiny black Black Beauty is a set consisting of a large rock weighing 320g and a pair of small stones. Scientists dated it and found that Black Beauty is the oldest Martian meteorite ever discovered on Earth.

An international research team led by scientists from Curtin University, Australia, with the help of artificial intelligence, confirmed where the meteorite came from on Mars, and recently published it in the international scientific journal Nature Communications. The hometown of the meteorite the researchers found is a crater in the northeastern part of Terra Cimmeria-Sirenum, in the southern highlands of Mars, where numerous craters are clustered. It is close to the area where the Mars robot rover Spirit landed in 2004. "This is the first time that the geological context of Mars specimens on Earth has been confirmed," said Professor Anthony

Possesses early material on Mars 4.5 billion years ago

The Black Beauty meteorite contains Martian matter from 4.48 billion years ago. 4.48 billion years is when only 50 million years have passed since the birth of Mars. Therefore, identifying the hometown of this meteorite is very important for elucidating the early history of Mars.

"The region identified as the home of this unique Martian meteorite is a window of truth into the early environments of planets, including Earth," said Professor Lagaine. On the other hand, the Earth has completely lost its original shape due to tectonic plate movement and erosion.

So far, about 300 Martian meteorites have been discovered on Earth. Black Beauty is the only breccia cancer among them. A breccia is a sedimentary rock that is hardened by a collection of small, angular particles. It is created by weathering, erosion, destruction of faults, or volcanic eruptions. Thus, unlike other Martian meteorites, which consist of only one type of rock, several types of rock fragments are combined.

The zircon crystals in the meteorite are the product of a devastating shock received 4.45 billion years ago. Scientists estimate that there must have been at least three impacts, given the state of matter in the meteorite.

One by one analysis with artificial intelligence and supercomputer

But among the 94 million large and small craters over 25 meters in diameter on Mars, it was very difficult to trace the home of the meteorite. The researchers analyzed the size and location of each crater using a specially developed algorithm and supercomputer.

First of all, as a result of analyzing crater photos taken by the Mars Reconnaissance Orbiter (MRO), it was found that most small craters are mainly distributed in large craters with a width of more than 3 km and formation within 10 million years. This means that the smaller craters may be secondary craters created in the aftermath of a larger primary impact.

The research team first selected 19 craters large enough to send debris from the impact into space as candidates for the hometown of the black beauty meteorite. After comparing the physical and chemical properties of each crater and Black Beauty, an exact match was found. The crater was rich in thorium and potassium, just like Black Beauty. The magnetism of the crater was similar to that of a meteorite.

The researchers named this crater 'Karata'. Karata is the name of an Australian city in the area where rocks (3.5 billion years old) that are now believed to be one of the oldest on Earth have been found.

Hope to elucidate the early history of rocky planets

According to the research team's analysis, the roots of black beauty can be traced back to the ancient times of Noakia on Mars. During this period, about 4.1 to 3.7 billion years ago, Mars had an atmosphere and was warm enough to rain, scientists estimate, and therefore had lakes, rivers and oceans. Researchers at the University of Arizona, who collaborated on the study, said Mars at the time would have had a crust similar to today's Iceland. And collisions with asteroids were very frequent.

One of the asteroids struck the Terra Cimeria-Syrenum region, creating a 25 km wide Dampier crater. Then, 1.5 billion years ago, another asteroid fell near the Dampier crater, creating the 40-kilometer-wide Kuzirat crater. In the aftermath of the devastating impact, the eruption covered the nearby Dampier crater. The eruption solidified into rock over the years. The rock that became the prototype of Black Beauty was formed at this time.

The third asteroid impact occurred between 5 and 10 million years ago. The impact left behind the Karata crater with a diameter of 10 km. In the aftermath, many fragments, including Black Beauty, were thrown from Mars and started wandering through space.

The research team believes that the algorithm used to find the hometown of Black Beauty this time can be applied to unlocking the secrets of other celestial bodies in the solar system, such as Mercury and the Moon.

The researchers also expected that the Karata crater could be an ideal landing site for future Mars exploration, which will investigate the early tens of millions of years of history of rocky planets including Earth as well as Mars.

Discriminatory words about “there are black people”

An American writer who was supposed to come to my event to meet readers and give a lecture suddenly canceled his attendance. Since he had informed many people and made reservations in advance, he had no choice but to be embarrassed. The reason for the cancellation was that the artist had sent a questionnaire in advance for the interview to be exchanged in Korea, but the questions were 'racist'. This question was carefully prepared by the interviewer who had read all of the author's books published in Korea. I looked closely at the questionnaire again. What was the problem?

He is one of America's most acclaimed writers, receiving numerous prestigious literary awards. Although he is black, he is not a writer who only focuses on black issues. But while he talks about the universal discrimination that humans face, he also uncovers deeper hidden truths because he's black. As he picks out the question, would he have made it uncomfortable for him to ask him what he thought about the poverty or situation of black people as a black person? Did he not use a word with a 'racial' smell in the process of translating it? It was not easy to find out what the obvious fault was. He also sought advice from English scholars who majored in modern literature, but he didn't get a pointed answer. Rather, there was a counter-review that the author was looking for an excuse to be capricious, or that he didn't like something else.

This is not the answer. continued to worry. Knowing this will help you to prevent this from happening in the future. The cartoonist I met at that time was <A black man sat next to me on the subway>. The author, a nursery school teacher, portrays the experiences she had while meeting her black boyfriend. When she went out with her boyfriend, she categorized the reactions of people she encountered. People staring/Screaming people/People who stop along the way/People who openly say “There is a black person”/People who point to “Look over there”/People who talk freely saying “There is something strange”/People who frown/“ Those who giggle, saying, "She can't come back anymore." What kind of person am I?

The reason for such a diverse and meticulous classification is that we have experienced so many of these reactions. When I'm having tea with my boyfriend at a cafe, I pause when Michael Jackson's music comes on. This is because when a boyfriend goes to a cafe, jazz, pop songs, or hip-hop often come out suddenly. If Korean music comes out after the song is over, it must have come out by chance, but if not, it must have been played with the intention of her boyfriend. In this case, did the cafe owner care? Or was it a manifestation of racist prejudice? How would you like to understand the heart of a person who is sensitive to even a single song in life? Like someone who sends a picture of his wife naked and asks him to go to bed, hearing stories of blatant prejudice, prejudice, and rudeness are heartbreaking. However, the highlight of this cartoon lies not in the shocking testimony, but in the pieces of prejudice that are hidden in life, saved while living with a boyfriend.

Children with smartphones in their hands instead of books

“Sir, what does this mean?” This is a question often asked by children. Blurred eyes or tilted head in class. Not only do they hear many words for the first time, but they also say that they do not know what they mean by the problem situations presented in textbooks.

Of course, I thought I would know, but to say that I don't understand the meaning is just embarrassing as a teacher. Compared to the children I met as a teacher for the first time, this situation is more common with children these days. What has changed? As I pondered, what was in the children's hands had changed. That's a smartphone.

The ability to know the meaning of words and to understand the meaning of sentences is called literacy. In order to develop literacy skills to read and understand texts, many such experiences are required. That experience comes from reading. When I was young, I read a lot of books. Reading the book, I had a lot of dreams and imaginations. But these days, kids have smartphones in their hands. Most of the chatting on smartphones by children is short, meaningless words, and there are many words with broken spelling. And images and videos are the main contents. As a result, children have fewer opportunities to access authentic texts, and their ability to understand texts declines, and they respond better to improvised photos and videos than to short texts.

Children's lack of reading has a huge impact on class time. First of all, children find it difficult to understand the contents of textbooks. And I don't understand the teacher's explanation. Because I do not know the meaning of words and lack the ability to interpret the meaning contained in the text, I lose interest in the class. I lose my concentration and I have other thoughts. In the end, you miss the flow of the class.

The reason children don't want to study is because they don't understand the content and the fun is lost. I hate listening to the next class even more because I don't understand the previous class. Because I do not participate in class and do not give presentations, I have fewer opportunities to be praised and recognized by my friends and teachers. When children have smartphones instead of books in their hands, children not only have poor reading comprehension but also have difficulties in learning, and the accumulation of such experiences can lead to a lack of confidence and a lack of challenge.

In the classroom, I meet children who read a lot of books. When I hit the paper while reading a book in the morning self-study class, I feel so sorry for it, and I can't take my eyes off of it until the moment I put the book in the drawer. I take out the book I've been reading and read it in my spare time. Such children do not find the content of the class difficult because they have accumulated background knowledge through reading and are equipped with vocabulary. These days, as the exams are written in an essay type and a narrative type, the sentences in the question are getting longer. Compared to these children, there are good reasons to have a book in hand instead of a smartphone.

Parents are worried that children who do not let their smartphones go to study will not be able to study, but the fact is that not reading books is a bigger problem. Mathematics and English studies can be taught at hagwons, but reading comprehension cannot be taught. It can only be cultivated through reading books. Even in subjects that seem to have little to do with reading comprehension, such as math or science, reading comprehension is fundamental to understanding the content.

Is your child holding a smartphone in their hand now? Instead of telling them to study, let's turn it into a fun book.

"Cradle" material that protects organic matter in Ryugu samples Hayabusa2 brought back

The Japan Aerospace Exploration Agency (JAXA) and others have discovered a substance and structure that seems to have played the role of a "cradle" that protects water and organic matter from being decomposed and changed by heat in the samples brought back from the asteroid Ryugu by the Hayabusa2 spacecraft. Research teams such as the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) made the announcement. There is a theory that water and organic matter on Earth were transported from other celestial bodies, and such structures may be the key to understanding the origin of water and the process from organic matter to life. A paper will be published in the British scientific journal Nature Astronomy on the 16th.

Motoo Ito, chief researcher at the Kochi Core Research Institute of the Ocean Organization of Japan, and others of the research team examined the sample in detail at a level of 1 micrometer (1/1000th of a millimeter) or less using a synchrotron radiation facility that analyzes the internal structure of materials. . As a result, we detected a large number of organic substances containing many hydrocarbons (aliphatic hydrocarbons) in which carbon atoms are chained together. According to the team, similar techniques have never been detected in other meteorites.

In addition, organic matter was intermingled in ``hydrated silicate minerals'' that are widely present in rocks of the earth. This mineral in the sample had a coarse-grained structure that was not easily affected by heat. For this reason, the hydrated silicate minerals can be considered to have played a role like a cradle that protects the water and organic matter from being decomposed and changed by heat when they are transported from other celestial bodies to the earth.

Meanwhile, the research team investigated the composition of "isotopes" of the same element with different mass numbers in hydrogen and nitrogen. As a result, the composition of hydrogen and nitrogen on Ryugu was found to contain more heavy isotopes than those on Earth. Previous studies have shown that materials in regions far from the center of the solar system tend to be rich in heavy isotopes of hydrogen and nitrogen. It has been suggested that Ryugu may have formed in the outer solar system, but the results of this analysis provide direct evidence.

Water-containing minerals and organic substances such as amino acids have been found in carbonaceous meteorites, a type of meteorite found on Earth. The home of these carbonaceous meteorites is asteroids such as Ryugu. While the Earth lost information about its birth due to heat and other factors, Ryugu is less affected by heat and still retains organic matter and hydrous minerals from the time the solar system was formed about 4.6 billion years ago.

How to Fix and Avoid Google Play (An Expert Guide)

There are lots of reasons why a Google Play app might not be working. It could be that your device isn't powerful enough, you have an old version of the Play Store app installed, or there's some other issue preventing you from using Google Play. Whatever the problem is, there are ways to fix it and ways to avoid these problems in the future.

1) Clear Google Play Services’s cache and data.

Clear Google Play Services’s cache and data.

Use the following steps to clear out your device's cache and data:

Go to Settings > Apps > Google Play Services.
Tap Clear Data (or Clear Cache). If you see a dialog box asking for confirmation, tap OK or Continue.

2) Make sure you have a strong Wi-Fi or mobile data connection.

If you are having trouble downloading apps, make sure that your Wi-Fi connection is strong enough. If the network is not strong enough then it could cause problems when downloading apps from Google Play.

If this happens to you, try connecting to a stronger network (such as using tethering or roaming) until your device can connect without any issues again.

3) Check your date and time settings.

Check your date and time settings.

The date and time is one of the most common causes of app crashes, especially those that occur on older devices. If you're having trouble navigating your phone or playing games, it's worth checking to see if something has gone wrong with your clock settings. You can do this by going into Settings > System > Date & Time (or Clock).

You should make sure that these are set correctly so that they match up with what's actually happening in real life—if they're too far off from what is happening outside your house or office, apps may not work properly or load properly without crashing.

4) Uninstall unnecessary apps.

The next step is to uninstall any apps that you don't use. This is a great way to free up space on your phone and make it easier to use. If there are any apps on your phone that you haven't used in a while, it's probably time for them to go.

Uninstall unused or unnecessary apps: If an app has been installed but not used since installing, then this can be removed from the list of available programs so that no other background processes are running in the background which can slow down performance and cause lag when using sensitive functions like navigation through Google Maps or searching for information online (e-commerce).

5) Remove your Google Account, restart your device, and then re-add your Account.

Remove your Google Account, restart your device, and then re-add your Account.

To remove your Google Account: Open the Play Store on your Android phone or tablet. Tap My apps & games . Select Settings from under Apps & notifications . Under "Google," tap Remove account . Tap OK to confirm that you want to remove this feature from the device. If you have multiple devices registered with a single email address (e.g., work@gmail), select Yes when prompted to delete all instances of that email address from all other devices before proceeding with steps 3-5 below.

* To restart any affected devices: Power down any affected devices by holding down both buttons until they turn off.

* Reinstall any apps using their respective links in this guide using either method described above.

* Try installing again once everything is up-to-date on all versions of Google Play Services

6) Don’t rely on auto-update.

Don’t rely on auto-update.

Auto-updates are a great way to get new features and bug fixes, but they can also cause problems if you don't know what you're doing. If an app is slow or crashes, it's more likely that auto-update is the culprit than actually being buggy software itself.

7) Update the Play Store app in the normal way (through Google Play).

Before playing again.
If an update is available, tap Update to download it immediately (if possible).

Postmodernism

noreply@blogger.com (Unknown) — Tue, 29 Mar 2022 16:13:00 +0000

What is Postmodernism?

"What is postmodernism?" is a question that has many answers, but few of them are particularly helpful. In this article, we'll try to answer this question. First, let's define postmodernism. What is postmodernism? What does it mean for our world? What is the point of this movement? This answer is important for understanding postmodernism, as it's a concept that's difficult to understand, even for those who've studied it.

Postmodernism is the result of the end of modernism. It aims to present the unpresentable by repeating the modern as if it were new and original, and demands that we acknowledge it. In other words, it's an attempt to make sense of the past by presenting the modern in a new and different way. Moreover, it demands that we acknowledge the past in order to understand and engage with postmodernism.

Postmodernism is a concept that challenges the traditional and the conventional ways of thinking and doing. This is considered an avant-garde. Its ideas have become central in works of art, literature, and architecture. It has been visible in marketing, law, and culture. It is not a new age, but a way to question the unsatisfactory circumstances of today. Despite its limitations, postmodernism recognizes the importance of the past and a desire to understand the new cultural conditions of the present.

What is postmodernism? It is a form of avant-garde that puts forward the unexpected and the estranged against the conventional. As such, it is not a style or a new age. Rather, it is an ethos that questions the unsatisfactory state of the world. Although it acknowledges the past and the influence of the modern, it reinterprets it.

Postmodernism is a phenomenon that has been the subject of intense debate for many years. In the past, it was defined as an intellectual movement that sought to redefine the modern world. Nevertheless, it has been a problem for people in various fields. For example, it is not relevant to the current situation in the United States. It does not distinguish between the past and the present. Rather, it refers to the way in which we live in the present.

While postmodernism is not a definite category, it does encompass some of the themes and orientations of postmodernism. Feminists are an example of postmodernism because they have criticized the traditional sources of power and the subordination of one sex to the other. However, this definition is not a definitive definition, and more research is needed to understand what it means for today's world.

Judith Butler was born in 1956 and argues that gender and sex are not radically different, but are socially constructed. Language, for example, is the medium through which we understand material things, including human bodies. Likewise, the era of postmodernism is a time of transition. There is no definitive definition of the term, but it is a time of societal change. Ultimately, it's a period of hyperconscious intertextuality and an overabundance of ideas and practices.

A defining characteristic of postmodernism is its tendency to conflate different aspects of the past. For example, the term pastiche means "to mix and match multiple elements". Many postmodernist authors use a combination of elements from different genres or styles. They often use historical figures and fictional characters. And some combine the elements of previous genres and styles. This is an example of a postmodernism book.

While postmodernism may seem like a new movement with some of its most influential writers, it remains the most relevant of all the genres in literature. Its goal is to challenge the notions of the past and posit an alternative reality. After all, the more we learn about the past, the more we will understand our world. The more we question, the more we understand. And the more we learn about ourselves, the more we can create the culture we want.

The term postmodernism has many definitions and branches. But it's a controversial concept, but there are some that are more helpful than others. Essentially, it says that there is no such thing as absolute truth, and that we are only limited by our own understanding of it. Its key advantage is that it acknowledges previous works in literature, which makes it more accessible. This is a big plus for many people.
