“The road to Hue is around. The green mountains and the water are like a picture”. As the old saying goes, the place of period attracts visitors by its charming landscape paintings mixed with contemplation, characterized by ancient architectural works in the shadow of time. The Complex of Hue Monuments is the first World Cultural Heritage of Vietnam, recognized by UNESCO in 1993. Photo: Le Huy Hoang Hai. Arriving in Hue, visitors seem to go back in time to the ancient world, where the Nguyen Dynasty used to be the capital for 143 years. Hue began to become the capital of the Nguyen lords from the 16th century, associated with mystical stories. Hue’s nickname of the land of God began to appear from the Nguyen Dynasty. According to cultural researchers, Neuro is a compound word between “capital” and “mystical”. Therefore, the land of Tinh means “mystical capital”. Photo: Le Huy Hoang Hai. The complex of Hue monuments are historical and cultural relics built by the Nguyen Dynasty from the early 19th century to the first half of the 20th century, including construction items inside and outside the Hue citadel. The cultural heritages in the citadel include Ky Dai, Long An Palace, Hue Museum of Royal Antiquities, Tinh Tam Lake, Tang Tho Lau, Xa Tac instrument… Photo: Le Huy Hoang Hai. Imperial Citadel located inside the citadel, has the function of protecting the Forbidden City as well as the most important palaces of the court. The Imperial Citadel and the Forbidden City are commonly referred to as the Citadel. Important works in the Imperial Citadel include Ngo Mon, Trieu To Mieu, The To Mieu, Dien Tho palace, Hien Lam Cac… The cornflower season here attracts many tourists. Image: Kuzumi Truong. Hue Citadel is a familiar scene in Vietnamese MVs and movies that attract young people like Can’t be together forever , Kieu , Very old girls … Truong Lang This is a check-in point that visitors cannot miss here. The long corridor with vermilion doors, exquisitely carved, bears the ancient and magnificence of ancient royal architecture. Image: Nguyen Ky Anh. Located on the main axis of the Imperial Citadel, between Ky Dai and Nghinh Luong Dinh, Phu Van Lau is a unique architectural work in the complex of relics of the ancient capital. This is the floor to keep the documents of the Nguyen Dynasty, where the king’s decrees or the results of the competitions of the Association and the Dinh are listed. On rainy days, this place is even more bold and ancient. Image: Le Huy Hoang Hai. Referring to Hue, it is impossible not to mention the majestic mausoleums such as Gia Long, Khai Dinh, Tu Duc… The works are still preserved quite intact, harmoniously combining the royal architecture with bold Asian style. and modern western style. The frame layout creates a special impression in Hue architecture. Photo: Le Huy Hoang Hai. More than 10 km from Hue city, Khai Dinh mausoleum was the last work of the Nguyen Dynasty. This is also the mausoleum with the most unique architecture in the ancient capital, showing the interference of two cultures East – West. The mausoleum is not too large. The impressive point that attracts visitors is the rectangular block architecture with 127 steps and the sophistication and sophistication in each carved line and pattern. Image: Pilgrimagevillageresort. Huong river is a famous landmark of the heritage city. Hue’s natural masterpiece has long been an inspiration for poetry and music compositions… On big festival nights, you can get on a boat down the Huong Giang river, drop flowers to pray for peace. The scene of shimmering, fanciful waves at night gives you interesting experiences compared to the daytime. Image: Le Huy Hoang Hai. From Trang Tien Bridge (or Truong Tien), you can admire the beauty of the Perfume River up close. The bridge “6 and 12 spans” connects the north and south banks of Hue city, is a charming highlight for the Huong Giang river. The symbol of the ancient capital is built of steel, more than 400 m long, with a beautiful design in Gothic architectural style. The rows of red phoenixes every summer make this place an unforgettable scene. Image: Le Huy Hoang Hai. Thien Mu Pagoda (Linh Mu) is located on Ha Khe hill, on the left bank of the Perfume River. The pagoda stands out with the towering Phuoc Duyen tower, surrounded by green nature. After coming here to worship, you can go down to the waterfront in front of the temple, get on a dragon boat to travel along the Huong Giang river. Image: Le Hieu. At the beginning of 2016, the newspaper HuffingtonPost (USA) has published an article about the famous abandoned water park in Hue, attracting domestic and foreign tourists to check-in. That is Ho Thuy Tien Park , a place that hides the ghost, the strange, attracts the adventurous and adventurous souls. Image: Le Huy Hoang Hai. If you have “worn your feet” in familiar places in Hue City, visitors can move further to the sea. Lang Co (Thua Thien Hue province). Sitting on the sand, listening to the soothing sound of the waves, watching the bay and blue horizon, visitors have unforgettable emotions when they are immersed in the nature of Hue.

Not only are your hands exposed to the sun more than other parts of the body, but they are also prone to fading from daily rubbing and activity, according to Tiny Tattoo Inc . In addition, you often use your hands to do everything, have to wash them often. Therefore, if you have a tattoo on your finger, it will fade faster than other parts of your body. However, you can slow down the fading by taking care of this position. Hands are a popular tattoo location. Photo: The Australian. Thorough care Tiny Tattoo Inc said, if you decide to get a tattoo on your finger, care will begin immediately after it is done. This healing process lasts about 6 weeks when your skin is most vulnerable. This is when tattoos are susceptible to environmental factors and body movements that cause them to fade. When you finish your tattoo session, make sure you keep the tattoo covered for at least 8 hours. Next, you carefully remove the bandage, wash the tattoo with warm water and a mild, fragrance-free soap. After that, you dry with a soft towel, absolutely do not rub or scratch. Finally, you apply a moisturizer intended for post-tattoo care. According to the Cosmopolitan The general rule of thumb when looking for a tattoo lotion is that it’s unscented, soothing, and moisturizing the area. Most finger tattoos are designed in the form of thin strokes. Photo: Nahmoojungwon. During the first 2 weeks, you need to cover the new ink stain as much as possible to avoid sunlight, dust and dirt. During this time, apply moisturizer at least twice a day or more. After this point, you avoid wearing jewelry on that finger, keep the finger clean and sufficiently moist. When you notice that the ink has come off, use sunscreen every day. Do finger tattoos hurt? Finger tattoos hurt more than other parts of the body. Because there is less muscle and fat around the finger, the needle of the tattoo machine will work directly into the bones and joints of your fingers. In addition, the hand is also a concentration of sensory nerves, which control our perception of pain. These nerves combine with thin skin and less fat to create a more painful tattoo experience. Because the nerves are concentrated mainly in the hands, this position will be more painful if tattooed than other parts. Photo: Weheartit. Another factor that contributes to the level of pain you will feel during the tattooing process is time. Hand tattoos are not large, except for designs that extend up the finger or down the wrist, but they often take a long time to complete. According to tattoo expert Astris Elisabeth, handwork requires high precision. In addition, this position is small and uneven, making it difficult to move the tattoo needle. 5 beautiful tattoo positions for beginners These are the ideal suggestions for the first tattoo.

The human brain is a complex multi-scale structure in which molecules, cells and neurons coexist. It can be modeled as a multi-layered network, called a brain connection pool. Neighboring neurons are connected to form local structures, and different local structures form connections to perform cognitive functions. The human brain is estimated to have about 86 billion neurons. To decipher where consciousness comes from, the researchers used a Swiss supercomputer and used algebraic topology to build a detailed model of the cerebral cortex. Through testing the response of the mathematical model to virtual stimuli and examining the reality of the mouse brain, the researchers were able to determine the details of the neural network on a single neuron. and the entire brain structure. At the same time it was discovered that there are different types of high-powered activity in the brain consisting of a three-dimensional geometric structure – tightly connected clusters of neurons and existing regions. space (cavity) between them. These empty regions appear to be important for brain function. When the researchers applied the stimuli to their virtual brain tissue, they found that the neurons responded to the stimulus in a highly organized manner. This means that as we think about problems, clusters of neurons will gradually coalesce into higher-dimensional structures, forming holes or voids of height. The more neurons in the clusters, the higher the size of the gap, and the highest limit that can be achieved is 11 dimensions. The whole process always follows the order from low to high, the structure will become more and more complicated and eventually collapse. It’s like building a castle on the beach, the castle gets taller and taller and eventually it will collapse on its own. This is exactly like the large-scale filamentous structure of the universe, where galaxies and galaxy clusters form a giant filamentous structure with a giant hole in the middle. In a recent study, it was discovered that our Milky Way galaxy lies within a giant hole one billion light-years across. This study provides new discoveries about how the brain processes information. Scientists speculate that high-dimensional gaps in neuronal structures may be where the brain stores memories, but it’s unclear how these blocks and gaps are formed. How it works, so further studies are needed to determine the connection between the multidimensional structure of neurons and complex consciousness. The interaction between the human brain and the universe is completely different, but there have been many observations and conjectures about the similarity between the neural network and the cosmic network under observation from a microscope and telescope. The researchers quantitatively analyzed the similarity between the two factors based on optical microscopy observations of brain tissue and high-resolution cosmic-matter network imaging, with the help of the method. network analysis. First, there is a huge difference in scale between the brain network and the cosmic network, which is similar only on a specific scale. Brain neural networks are now thought to consist of tens of billions of neurons. The number of galaxies currently observed in the cosmic lattice exceeds 100 billion. In addition, in the neural network of the brain and the network of the universe, only a small amount of matter constitutes the network. There are a large number of holes between giant galaxies, and about 70% of the mass is made up of dark matter. In the human brain too, which is a biological organ, the most important component is water, in the human brain, nerve cells are only 25% and about 75% water. Up to this point, “having water in your head” has a certain scientific basis. In the universe, dense clusters of galaxies predominate, while in the human brain, specifically in neural networks, nerve fibers create uniform small patterns. However, when the researchers increased the magnification of the microscope, they were able to see some similarities to the cosmic web in brain slices.

The authors of Ho Chi Minh City University of Technology have applied blockchain technology to build a system for issuing and managing diplomas and certificates. To issue a certificate, the training institution registers an account and logs in to the system to create embryos. After filling in the student’s information, the course, etc., the training institution can print it to issue a certificate or issue a digital certificate. Each certificate is issued with a QR code, which can be looked up and verified on the student’s information and the certificate on the mobile application. The system helps to reduce time and costs for training institutions and quickly detect cases of tampering. The glue that helps regenerate nerve cells Researchers at the University of Georgia (USA) have studied a special glue in the form of hydrogel to aid in the recovery of brain cells. The researchers implanted the hydrogel into mice with traumatic brain injury. After 20 weeks, the mouse’s cell repair process was enhanced, motor function improved. The results showed that this glue not only protects tissues from damage, but also regenerates functional neurons at the affected site. The results of the study hold promise for the medical profession to prevent cognitive decline or tissue loss in patients with traumatic brain injury. New battery development Russian scientists have developed a new type of battery that can be charged about 10 times faster than commonly used lithium-ion batteries. Tests show that the new battery can work well in emergency charging situations and in low-temperature environments. The new battery is also safer for the environment.

This species is extremely toxic, it prefers to hide in coral reefs, rocks and sandy seabeds from intertidal to intertidal zones in southeastern China and tropical seas. Their bodies contain more than 200 pharmacologically active substances and a single drop of venom can kill 20 adults. To date there have been at least 100 recorded deaths from the venom of this species and the actual number could be much higher. The creature we are talking about here is the Cone Snail, also known as the cone snail, is a marine gastropod mollusk, so far more than 70 species have been found along the coast. along the coast of China and there are more than 1,000 species discovered in the world. Their venom is made up of a mixture called peptide conus. Each of them will have a unique venom formula. More than 50,000 conus peptides have been discovered, they are all neurotoxins and no vertebrate species on our planet possesses this form of venom. The Cone Snail has a mostly cone-shaped appearance and the largest can be 23 cm long. They are purely carnivores and predators, feeding mainly on sea worms, small fish, mollusks and even other cone snails. It can release venom at any time in its life, and this species is always ready to wipe out all living things around it. But surely you will find it difficult to understand because in our impression, snails are very slow-moving mollusks, how can they hunt, especially fast-moving species like fish? In fact, the secret to their hunting is not in their movement speed, instead they hunt by using their venom and developing an extremely efficient venom system. All cone snails are masters of poisons, likened to the five poisons in the animal kingdom. They have a tongue pocket in their throat, which contains many hollow toothed tongues, which resemble spearheads and are made of hard chitin. Because of their slow movement speed, cone snails often hunt by “holding a tree and waiting for rabbits”, which will lie in the sand at the bottom of the water, only revealing their long tubular mouth and tentacles in the sand. Once it detects prey such as a small fish or something passing by, it will use strong muscle contractions to shoot the tongue connected with the venom gland from its long tubular mouth at lightning speed and “close the gap”. nail” into the body, injecting poison into the prey. This venom will paralyze prey within seconds and die instantly. To prevent their prey from struggling, some species of snails have created a toxin that can reduce pain and anesthetize the prey’s nerves, making the prey feel no pain and slowly die without even realizing it. know. When the prey is fixed and no longer struggling, the conch will withdraw the “hook” (toothed tongue), pulling the paralyzed prey into the mouth. It’s worth noting that even when it’s not during mealtimes, if it feels threatened, the conch shells will shoot out without hesitation. So if you see brightly colored and beautiful cones on the beach, don’t stress. It came out by accident. Pick it up, especially the larger cone snails. This behavior can kill you because the conch’s nose can pierce the skin, gloves or wetsuit. Especially among cone snails, there is a species called Gastridium geographus, also known as geographical cone snail, killer snail, they are known as one of the most poisonous snails in the world, and one of the most dangerous snails in the world. marine animals that are extremely toxic to humans. One study estimated that this species alone caused 36 deaths. Symptoms of a snail sting include local pain, swelling, numbness, tingling, and vomiting. Symptoms may appear immediately or slowly over several days. In severe cases, muscle paralysis, vision changes and respiratory failure can lead to death. The various neurotoxins contained in cone snails are called cono toxins. In addition to being toxic to humans, in this venom mixture there are many beneficial substances, which can work accurately and quickly on the human nervous system without causing side effects. Therefore, this snail can also open up a new medical future for humans. For example, cono peptides have the potential to prevent spasticity caused by spinal cord injury and may help diagnose and treat small cell lung cancer. Conotoxins can immediately generate nerve signals that reduce heart rate or turn off pain receptors. Ziconotide isolated from it is used as an analgesic. It is said to be 1000 times more effective than morphine and not addictive. Conotoxin ACV1, isolated from Victoria cone cone in Australia, is more effective than morphine and Ziconotide, has a longer analgesic effect and is convenient to use without side effects. It has been shown to be very effective in the treatment of post-operative and neurological conditions, and even accelerates the recovery of nerve damage, and is expected to be developed as a treatment for anxiety. , Parkinson’s disease, muscle tension and hypertension.

Cutting leg nerves to have slimmer calves is being seen as a horror beauty trend in China. It’s crazy that some people will in the name of beauty, or follow so many strange beauty trends to achieve “body perfection”. Take, for example, the new and disturbing trend known as “calf block,” which is essentially young, healthy girls who assume that there are “less important” nerves in their legs to be operated on. amputation to permanently atrophy the calf muscles, thereby making the legs appear slimmer and straighter. In an interview with The Paper on May 20, Doctor Zeng Chun – Deputy Director of the Department of Joint Surgery and Sports Medicine, Affiliated Hospital 3 of Nam Medical University said: He was shocked when he heard the news. One girl had some nerves removed in her legs to make her calves look slimmer. Patients with nerve injury and calf muscle atrophy, constant pain need to find ways to recover. But I didn’t expect that there are healthy people who actively destroy their nerves,” said Dr Zeng, adding that there is no such thing as a less important nerve, and once the nerve has been If it is damaged, there is a high chance that it will never fully recover. Doctor Zheng Chun explained that to treat a broken bone is quite easy, but once the nerve is damaged, there is a high chance that it cannot be restored. On online forums, the keyword “calf block” is searched by many people in the hope of having a solution to help slimmer calves. According to information shared from these service providers, customers will have some less important nerves removed in the calf, gradually the muscles will be weak and atrophy, helping to make the legs smaller and straighter. On Good Doctor Online, a girl who has performed this surgery said that two months after the operation, she still could not walk normally, her legs were numb, and she could not stand on her feet. She was very worried, scared and asked the doctor if there was any way to fix it. Following the revelations in The Paper’s article, this disturbing beauty trend has gone viral in China, where many beauty bloggers and vloggers blame the promotion of this type of trick, but also girls. undergoing unproven surgeries in a desperate attempt to achieve unrealistic beauty standards. Unfortunately, this isn’t the only shocking beauty trend that has popped up over the years. Beauty trends such as tattooing, tattooing pupils, dilating lips, splitting tongues, piercing, surgery to resemble animals … are considered the most shocking bizarre beauty trends on the planet.

The brain produces enough electricity to light a small light bulb Our brain has about 100 billion cells called neurons. When we move, look, think, dream or laugh, electrical and chemical signals are racing between the billions of neurons on this neural highway. So even though one neuron generates a very small amount of electricity, all of them together can generate enough electricity to light a low-wattage light bulb. Illustration. The sense of smell can take you back in time When we smell something that has a connection with something significant in our past, the first thing we experience is the emotion we had at that moment, then memory often follows. Sometimes we won’t remember the event or situation, but the emotion will be there. This ability actually has a very simple evolutionary explanation. There’s a part of our brain that’s dedicated to detecting chemicals that will signal us if something is approaching, that’s what our sense of smell does. This was very important to our existence in the past. Illustration. We can lift a 60kg person but cannot lift a 60kg rock When we lift “live weight” it is easier because the person can adapt to gravity and distribute their weight in more directions. If this person chooses, they can also put their arms around you, which will make things easy. While lifting an object, such as a rock, the rock cannot choose the distribution of its gravity and weight. Gravity is in the default position and this makes lifting it a lot harder. Illustration. Women’s brains shrink during pregnancy A study confirms that “pregnancy brain” is more than just a phrase used to explain the emotional roller coaster a mother-to-be goes through. The brain actually shrinks during pregnancy, but this is not a negative thing. As it gets smaller, it becomes more effective and the woman prepares for becoming a mother. In fact, the loss of gray matter occurred in the part where it would enhance her understanding of other people’s beliefs, emotions, and nonverbal cues. These changes will boost her ability to bond with her infant and make her aware of threats so she can protect her baby and herself more quickly. To have super strength, the digestive system has to shut down Fatigue, pain, and fear are all things that prevent us from trying to use our strength in our daily lives. We’ve all heard stories about a man lifting a car to save his loved one. That superpower actually comes from adrenaline, but for it to work fully, it needs to shut down the digestive system and immune response. Then the combination of increased energy levels and increased oxygen levels strengthens our muscles beyond normal. Illustration. We can see with our ears Blind people can walk by using canes or clicking on echoes that tell them about their surroundings. But scientists have actually studied the brain of a blind man named Daniel Kish. He described his vision as “something like seeing the world in dim rays”. So when his brain is being studied, the part that controls his visual context actually lights up as he listens to the echoes that help him navigate by clicking. However, when he was listening to other sounds, the area was pretty quiet. This led the scientists to conclude that Daniel was indeed experiencing something like visions. Illustration. Headaches signal bad weather For some people, headaches are not just a signal that we are too tired or overworked, but also a prediction of the weather. In fact, research has confirmed that a number of headaches, ranging from mild to severe, are caused by weather changes. While for some people it can be a rapid increase in temperature or pressure and usually during a storm. During a storm, warm and cold air mix and create a change in air pressure (barometric pressure). In fact, this is how thunderstorms, rain and wind are created. This type of air pressure actually exerts force on a certain area, and in the case of headaches, this “zone” is you. Illustration. The brain has the capacity to store 2.5 petabytes of memory Our brain has about 1 billion neurons. Each cell makes 1,000 connections with other neurons, a trillion connections in total. This gives the brain about 2.5 petabytes – 1 million gigabytes of storage. If we compare it to the length of a digital video, it would be 3 million hours for TV shows, making the video run non-stop for over 300 years. Embryos can heal mother’s wounds There have been many studies involving pregnant women and their unborn babies. The results of these studies have given scientists a new light on the strength of the fetus. During pregnancy, the cells of the embryo move out through the placenta and reside in different parts of the woman’s body. This can affect the mother’s health. In fact, these cells remain inside the body for more than a decade even after the baby is born. They can help the mother heal from injuries during pregnancy. The human ear has the ability to “hear” molecules Illustration. You can take 2 glasses and pour hot water in one and cold water in the other, and when you do this, you can hear the difference. This is because the molecules in cold water have less energy, producing low-frequency tones while hot water has more energy and produces higher-pitched tones, and we can hear and distinguish well between the two.

Chinese blogger was criticized for sharing about “goblin ear” surgery. “Goblin ears help me look a lot younger. With the elongated earlobes, my face becomes smaller, the lines are more elegant,” Chen shared. Chen’s story quickly caused a great controversy when many people believed that the female blogger’s shares were promoting a beauty trend that was weird, toxic and dangerous to health. Li Zhengyong, deputy director of the Department of Aesthetics and Burns, West China Hospital of Sichuan University, said that “goblin ear” actually refers to a birth defect in the ear. A person with normal ears who wants to have surgery to become “goblin ears” will have to take cartilage from several places on the body to cover the earlobe. “This type of surgery can cause dangerous complications, and the consequences are unpredictable,” Dr. Li said. Not only doing “goblin ear” surgery, Chinese young people also follow many strange beauty trends to achieve “body perfection”. Another controversial cosmetic trend recently is cutting nerves to have slim calves. In an interview on May 20, Dr. Zeng Chun, Deputy Director of the Department of Joint Surgery and Sports Medicine, Affiliated Hospital 3 of Southern Medical University, said he was shocked when he heard that a girl had died. get rid of some nerves in your legs to make your calves look leaner. Many people blindly believe in neurectomy for thinner calves. “Patients with nerve injury and calf muscle atrophy are very painful, they find ways to recover. I did not expect that there are healthy people actively destroying their nerves,” said the doctor. doctor expressed. On online forums, the keyword “calf block” is searched by many people in the hope of a solution to help slim calves. According to information shared from these service providers, customers will have some less important nerves removed in the calf, gradually the muscles will be weak and atrophy, helping to make the legs smaller and straighter. Doctor Zheng Chun explained that to treat a broken bone is quite easy, but once the nerve is damaged, there is a high chance that it cannot be restored. Zheng also asserts that no nerve is considered less important in the body. On Good Doctor Online, a girl who has performed this surgery said that two months after the operation, she still could not walk normally, her legs were numb, and she could not stand on her feet. She was worried, scared and asked the doctor if there was any way to fix it. However, she could not find an answer. Many netizens expressed frustration when many girls still believe in unscientific surgery because they want to have a perfect appearance and harm themselves. On the other hand, bloggers sharing about the “calf block” method also received a lot of criticism when creating a malicious trend.

According to a recent report by the US Senate Intelligence Committee, the number of suspected cases of Havana syndrome worldwide is increasing. According to the New York Times, there have been more than 130 US officials with this neurological syndrome worldwide in the past 5 years, and at least one person has had symptoms in the past two weeks. The figures have raised concerns within the Biden administration, especially as the cause and cure for Havana’s syndrome remains a mystery. Havana syndrome first appeared in US officials five years ago. “Unusual health incident” “ How can you fight something you don’t know well? “, a US intelligence official expressed concern about the mysterious Havana syndrome. Under pressure from lawmakers and victims of Havana syndrome, the Biden administration has stepped up efforts to “identify the cause of these unusual health incidents,” according to a statement from a spokesperson at the office. Office of the Director of the National Intelligence Service (CIA) on May 18. However, the reality shows that it is difficult to pinpoint the exact causes and symptoms of Havana syndrome. Victims of the syndrome report a multitude of different symptoms. This has scientists, engineers and medical professionals fiercely arguing about whether all cases of Havana stem from a single cause. CNN’s source said the US government has found a blood test that can detect some signs of Havana syndrome. The test was applied to intelligence officers with a recently discovered neurological syndrome, and at least one of the victims was a White House official. But testing alone is not enough information to make a definite diagnosis of this strange disease. Many Havana syndrome research institutions are developing a type of sensor device that can detect abnormalities to identify victims. However, this tool only helps detect the syndrome and cannot protect or improve the condition of the sufferer. The Biden administration has stepped up efforts to determine the cause of Havana syndrome. (Photo: CNN) Foreign secret weapon? In March, the US National Academy of Sciences reported finding “directed radiofrequency energy” most likely to be responsible for a series of strange neurological symptoms of Havana syndrome. This is called the “microwave theory”. However, US officials note that this theory has not been confirmed, some scholars have openly rejected the theory. CNN’s source said that the content of the microwave theory is purely based on external symptoms. This theory is not convincing because Havana syndrome victims have many and different symptoms. In 2014, the US National Security Agency revealed that intelligence on cases of officials with Havana syndrome since 2012 indicated it could be caused by “a high-powered microwave weapon capable of can produce a variety of effects on the human body, including damage to the nervous system.” But the National Security Agency has not confirmed the existence of this dangerous weapon, or information about the country that developed it. The US National Security Agency revealed that Havana syndrome could be caused by “a type of microwave weapon”. (Photo: CNN) Many US officials question how such a weapon could be so charged and so precise that it only damages the target’s brain. And equally important is if Havana syndrome is a man-made attack, who or what organization is behind this conspiracy? According to the US official, there is some evidence that Russia is likely to be the culprit because it is one of the few countries that has researched and developed a tool that is believed to be the weapon that causes Havana syndrome. Some researchers on Havana Syndrome say that if the cause of the disease is advanced foreign equipment, the purpose of its creation is to gather information from US officials. “ I don’t know if they happened to find a mechanism that would allow it (Havana syndrome) to be used as a weapon system, or are they just trying to collect (data) that could be detrimental to the country. America “, a CNN source said. To date, the investigation into this mysterious neurological syndrome is still ongoing, there is currently no evidence to prove that Havana syndrome is created by forces hostile to the United States, or the symptoms and treatment for this disease. those infected.

The software helps to record the thoughts in the brain into writing on the computer. The combination of mental effort and modern technology has allowed a motionless man (T5) to communicate by text at a speed comparable to that of healthy colleagues texting. on smartphone. Study participant (T5) almost lost all mobility below the neck because of a spinal cord injury in 2007. The scientists placed two brain-computer interface chips, each about the same size. an aspirin pill, on the left side of T5’s brain. Each chip has 100 electrodes that pick up signals from trigger neurons in the motor cortex, an area on the outermost surface of the brain that governs hand movements. Those neural signals are sent over wires to a computer, where artificial intelligence algorithms decode the signal and infer the T5’s intended hand and finger movements. Algorithms were designed in Stanford’s Neural Prosthetic Translation Lab. T5 generated text at a rate of about 18 words per minute (the average person can say about 23 words per minute on a smartphone). Even, T5 then reached a record of 40 characters per minute. The study was published online May 12, 2021 in the journal Nature. It offers hope to hundreds of thousands of Americans and millions around the globe, who have lost the ability to use their upper limbs or speak due to spinal cord injury, stroke or amyotrophic lateral sclerosis.

Feng shui expert Phung Phuong shares the great cavalry in the bedroom area that can attract vitality in your home. The bedroom is too long and narrow If the bedroom is too narrow, it will cause inconvenience and limitation in daily activities. If people sleep in a long and narrow space, they will feel lonely and cold. Mentally sensitive people often think miscellaneously, which gives rise to many hallucinations The bedrooms of 6m2-10m2 will cause suffocation, thereby leading to fatigue and stress in study and life. The bedroom area is too big People often think that the larger the bedroom area, the better because it will feel spacious. But in fact, in feng shui, a bedroom that is too large is also a crime First of all, we see that the “human energy” mentioned in feng shui is the energy field of the human body that radiates energy out, like an air conditioner. The larger the bedroom area, the more energy is wasted, thereby reducing immunity, mental fatigue, reduced working capacity, even leading to illness. So the area of ​​the bedroom is stable and most suitable according to feng shui is from 10 -20 m2.

In their paper in the journal IEEE Trans Transaction on Biomedical Engineering, the team presented the results of trials on two men with spinal cord injury aged 35 and 63. The system works by connecting a signal generator on the user’s head to an electrode relay in the cortex, through the connection port like wired systems. From there, the tester can move, click and type on the computer keyboard with his or her brain. Transmitter connects to a relay located in the brain cortex, helping people to use wireless computers. Photo: BrainGate. In the test, both candidates were able to achieve typing speed and click accuracy on par with a wired system. At the same time, they can use the system continuously for up to 24 hours at home. “The signals are recorded and transmitted with the same fidelity as a wired system, meaning we can use the same decoding algorithms that we have,” said John Simeral, who leads the team. used with conventional wired equipment ”. “The only difference is that we are no longer physically tied to the devices, which opens up new possibilities for future research,” Simeral added. “With this system, we are able to look at brain activity at home, over the long term, in a way that was previously almost impossible,” said Leigh Hochberg, another team member. This gives us more opportunities to create algorithms that allow people with paralysis to move and work. ” According to the Mashable, The aforementioned study is a significant step forward in the field of neural communication, in which the human brain is directly connected to the computer. Recently, big names in the tech world like Facebook and Elon Musk have also expressed interest in this area. Simple device is placed on top of research candidate. Photo: Radiofiji. In 2020, Elon Musk’s startup Neuralink introduced a pig named Gertrude, with a computer chip implanted in the brain. Or, as before, in 2021, the company also succeeds in implanting a chip into the monkey brain so that the animal can play video games. However, Brown University’s first human study demonstrates that the technology can be used wirelessly, and it wouldn’t be surprising if we find wearable devices that allow people with disabilities to communicate with them. continue and work better in the future.

The team at Kyoto University Japan has created inducible pluripotent stem cells (iPS) that can overcome the immune system’s failure to accept transplanted cells in cell treatments. The research team is headed by lecturer Akitsu Hotta at the iPS Research and Application Center of Kyoto University. The team said they used gene editing to replace proteins on cell surfaces, which can cause the immune system to reject transplanted cells. According to the researchers, through animal testing and other means, they have confirmed that the iPS cells they generate reduce the risk of transplant rejection. IPS cells can be used to create cells that can regenerate any type of tissue in the body. Their method is able to generate 7 types of iPS cells and is applicable to more than 95% of the Japanese population. Previously, researchers at Keio University – Japan submitted a proposal to the Government for a clinical trial using iPS stem cells to treat patients with spinal cord injuries. Each year, about 5,000 people are said to lose the ability to move their limbs due to spinal cord injuries, the disease currently has no effective treatment. IPS cells can be used to create replacement cells for any tissue in the body. The team’s goal is to transplant cells into the patient so that these cells develop into nerve cells that transmit signals from the brain to restore the ability of the patient to move arms and legs. Japanese researchers have also made significant strides in their efforts to seek treatment for Parkinson’s disease (fibrillation paralysis). According to the group of researchers, for the first time in the world they have successfully transplanted iPS stem cells into the patient’s brain. “We did the transplant for the first time. The patient is recovering well now ”. GS. Ryosuke Takahashi at Kyoto University said. They performed this groundbreaking surgery recently, which implanted 2.4 million iPS cells into the brain of a 50-year-old male patient. The purpose of this procedure is to prevent Parkinson’s disease from causing depleted neurons. business. The research team will follow the patient for about 2 years to evaluate the safety and effectiveness of this method. Not stopping there, the above research group has developed iPS into the precursor cells of the reproductive cells. These cells were then cultured for about 3 months, in the same box as the oocytes isolated from the pups. The team claims to have obtained spherical cells with large cell nuclei. After analyzing the shape and characteristics of these cells, the team concluded that these are oocytes, the precursors of oocytes. The team says the work will help develop techniques for making human eggs from induction pluripotent stem cells. They can explain the cause of infertility through research on egg formation. Stem cells can develop into every other type of cell in the body. Breakthroughs … The pioneer in this technology is the laboratory of GS. Shinya Yamanaka at Kyoto University, Japan. In 2006, he published four genes with specially coded transcription factors that help transform from adult cells to multipotential stem cells. Together with Professor John Gurdon, he was awarded the 2012 Nobel Prize in Biomedical Sciences for “discoveries of adult cells that have the ability to be reprogrammed to become multi-potential stem cells”. Previous studies have concerned that reprogramming adult cells into iPS poses major risks, making the method limited in humans. For example, if a virus is used to alter the genotype in a cell, some oncogene expression genes are likely to be activated. However, scientists have announced the invention of a technology that helps to remove cancer-causing genes after multi-potential induction, making the application of iPS in the treatment of human diseases become more feasible. time is over. Currently, iPS cells are opening up a promising research direction in the treatment of genetic diseases in humans such as Down or polycystic kidney disease. In addition, iPS cells from impaired patients, which are not observed in iPS cells from healthy people, also provide additional physiological insights into these diseases.

1. Wrinkle reduction: Medical News Today says studies have shown pillows to compress the skin while sleeping, especially in people on their stomach or on their backs. Over time will cause wrinkles and other signs of aging. In the beginning, sleeping without a pillow can make you uncomfortable, but it has many benefits in the long run. Image: napodpktor. 2. Prevent back pain: The shape and size of many pillows can lead to an unnatural sleeping position. If you are new to not using pillows, choose a thin, light product for spinal alignment. Image: mattress express. 3. Avoid neck pain: If you don’t use a pillow, your head will be in a natural position. This helps prevent damage to nerves and muscles, helping you to experience less pain. In addition, pillows that are too soft also disrupt blood circulation to the neck, causing discomfort. Image: marylandpainandwellnesscenter. 4. Prevent acne: Acne is the result of dirt and oil build up on the face of the face clog pores. During sleep, your face will often stick to your pillow. Because pillows can become a breeding ground for bacteria, the skin condition worsens. Therefore, you should wash all pillowcases and sheets regularly. Image: skinclinics. 5. Skin is smoother: Your body needs to be hydrated to make your skin plump. However, cotton pillowcases can absorb the nutrients on your skin and make your skin less healthy. So, practice the habit of sleeping without using pillows to help smooth skin. Image: into the gloss. 6. Reduce skin irritation: If you have sensitive, acne-prone skin, sleeping on cotton pillows may not be the best option. Too coarse material rubs on the skin causing irritation, aggravating existing skin conditions. Therefore, you should switch to silk fabric instead if you are new to not using pillows while sleeping. Image: sesderma. Why are you prone to acne? Certain daily habits can cause breakouts, affecting your appearance.

Foot massage will have a good impact on your health For the massage to be most effective, you should follow these steps: Soak your feet in warm water (about 38oC) for 10-15 minutes with herbs or essential oils. Herbs will make blood circulation better. If you soak your feet in essential oil, it will feel soothing. Use a soft towel to dry your feet. Lie on the massage bed so that your feet are comfortable. Cover your feet with a towel to keep them warm. Using essential oils or massage creams, massage evenly on your hands until warm, then massage. Use your thumbs to gently, slowly massage from the top of your toes, then slide behind your feet and up your ankles. From there you go back to where your toes are. Repeat this movement about 3-5 times. Gently stretch the hand grip on the foot, pull up and down 3-5 times. This will help your feet fully relax. Use your thumb and index finger to gently massage in a circle, under the base of the foot, 1-5 times more. Use the thumb to gently squeeze from the heels down to the toes, repeat 3-5 times. Place 1 hand under the heel, the other hand embraces the foot and then rotate, perform gentle movements, 3-5 times for each rotation. This movement minimizes stiffness of the foot joints. Use your fingers to slide between the slits of your toes, from front to back, about 3-5 times. Use your thumb to circle around the ankle bone. With the soles of the feet, use your thumb to move in a continuous circle up and down, and at the same time to the sides. Then, with one middle handle behind the ankle, with the other hand, use the force of the cheek in the hand moderately to slide from head to foot (repeat about 5 times). Finish the massage by gently stroking from the ankles to the toes from the top and bottom again with your hand.

Researchers have gathered tissue samples from patients for brain research after death. Accordingly, the “zombie” gene may influence the study of brain-related diseases if the team prolongs the time to access the sample. The researchers analyzed gene expression from living brain tissue and found that in some cells, gene expression increased after death. They observed that inflamed glial cells develop and grow arm-like branches several hours after death. “Most research confirms that all activity in the brain stops when the heart stops beating, but not really,” said Dr. Jeffrey Loeb, Dean of the Department of Neurology and Rehabilitation at the University of Illinois Medical School. , Chicago. The “zombie” genes are activated after the brain stops working. They are glial genes responsible for attention to damaged brain tissue. Photo: Dr. Jeffrey Loeb / UIC. According to the Yourgenome.com Gene expression is the process of converting genetic information in DNA into functional products such as proteins or other molecules. “It’s not surprising that glial cells develop right after the heart stops beating. These cells become inflamed and their job is to clear things up after brain damage such as hypoxia or a sudden attack. Stroke, “Loeb said in a university press release. Also according to him, the connections are very remarkable. Most research uses post-mortem human brain tissue to find treatments for disorders like Autism, Schizophrenia, and Alzheimer’s disease. However, these studies did not take into account continuation of gene expression or cell activity. “Our findings will shed light on research on brain tissue in humans. It’s just that at this point, we haven’t yet quantified the changes,” said Loeb. Loeb is the director of UI NeuroRepository (at the University of Illinois), a bank that stores brain tissue, with consent, of patients with neurological disorders. Brain tissue is collected and stored when the patient dies or is in surgery. Not all brain tissue is needed to diagnose the disease, some of which is used for research. Loeb and his team noticed that the gene expression patterns in living brain tissue did not match any previous findings of brain tissue gene expression after death. Therefore, they conducted a simulation experiment to observe the expression of all genes in the human body 24 hours after death. As a result, about 80% of the genes maintain relative stability within 24 hours. These include genes that provide basic functions of the cell. Another group of genes, brain activity (such as memory, thinking, and seizure) quickly subsides within hours of death. A third group of genes – the “zombie” gene – became more active while the other groups of genes gradually decreased activity. During the first 12 hours of brain death, activity of the “zombie” gene peaked. “We found 1,427 genes clustered. A cluster of 317 rapidly depleted genes was predicted to be neuron and coincided with genes dependent on activity. The second cluster of 474 genes is predicted to be glia, consisting of astrocytes and microglia. Notably, due to the rapid decrease in the cluster of nerve cells, the glial cell cluster has significantly increased “, the scientists shared. These findings mean that researchers need to take these changes into account and minimize the time from death to study as much as possible to curb those changes that are too big, Dr. Loeb said. “The good news is that we know which genes and cells are stable, are decreasing, and which are increasing over time, which helps guide post-death brain research better,” he said. Therefore, naming the genes that are most active in the brain after death as “zombies” only makes this research more remarkable. This has nothing to do with the zombies in the sci-fi movies. Understanding the brain’s chemical signals is key to helping scientists find ways to cure brain-damaging diseases like Huntington’s chorea. This research was supported by an abundance of resources from the University of Illinois neuroscience archive, a collection of brain tissue samples with epilepsy and other ailments.

The rare disease ‘lurks’ through pain in the neck and neck pain

Ms. H. was admitted to the hospital for examination in the condition of pain in the neck and neck area, right shoulder pain, and numbness increased for nearly 2 months. The pain symptoms are not related to movement, still pain, feeling heavy and reduce the strength of the right hand muscle during work. Symptoms do not improve with rest, massage, acupressure, or warm compresses.

Doctor Vu Hai Yen – Neuroscientist Specialist at Thu Cuc General Clinic – 32 Dai Tu, Hoang Mai, Hanoi, under Thu Cuc Medical System) said that Mrs. H. had a healthy history. family and 2 children, who are office workers and travel regularly by motorbike. or degenerative cervical vertebrae, a common disease in office workers. But the special thing is that through the examination, patient H. does not recognize heat and cold in his right hand, does not know pain even though his right arm is cut, his left arm is still normal. In addition, the tendon reflexes in the patient’s right arm are also reduced, even without reflexes. In the presence of these suspicious signs, I have assigned the patient to have a MRI of the spine and spinal cord to assess the condition of the injury and to rule out other related diseases..- Dr. Hai Yen said.

Magnetic resonance imaging MRI is considered “the gold standard” in the diagnosis of diseases of the brain, eye socket, spine, neck area, pelvic abdomen, musculoskeletal area, mammary gland … (illustration)

Diagnostic radiologist Nguyen Chi Phon – Thu Cuc General Clinic said: “In Ms. H.’s case, it was MRI of the spine and spinal cord with an injection of magnetic antagonist to detect nerve damage. This is the most reliable tool to diagnose hollow spinal disease. For those who suspect that the patient has a hollow spinal cord, if only X-ray or computerized CT scan is indicated, it will be difficult to accurately assess ”.

The image obtained from the MRI of Mrs. H.’s spinal cord MRI shows that in her spinal cord a hollow of fluid is formed, which accumulates to form cavities and cavities, this is a manifestation of the root. hollow marrow disease. Immediately after the results of the subclinical examination, Thu Cuc’s doctors consulted to determine the cause of the disease and find the best treatment for Ms. H.

Early detection is an important “key” to protect health even in rare cases

According to chiropractors, osteomyelitis is caused in the spinal cord forming a hollow in the center of the gray matter containing cerebrospinal fluid. Cerebrospinal fluid accumulates to form cavities or cavities that grow and cause damage to the marrow, pinching nerves, making the disease manifest as movement disorders, sensory and nutritional disorders. The disease is often discovered by chance when examining related diseases or when having symptoms such as neck and neck pain, numbness of the hands, loss of feeling of muscle weakness, muscle atrophy, loss of tendon reflexes, loss of sensation. pain or heat, especially in the hands.

It is known that syringomyelia is an uncommon chronic disease in the spinal cord with the incidence of 8.4 / 100 000 and is common in the age of 20-50 years old .. The disease can be found in the neck, chest. and lumbar, however, the most common prevalence lies in the border between the cervical and thoracic marrow.

There are many causes of myelosuppression, including some idiopathic cases (the cause cannot be determined). Some have root causes such as: birth defects of the spine; after injury; lumbar spondylitis …

The pulp is empty due to the formation in the cavity containing fluid to gradually develop, causing pressure and damage to the marrow. (illustration)

There are many causes of myelosuppression, including some idiopathic cases (the cause cannot be determined). Some have root causes such as: birth defects of the spine; after injury; lumbar spondylitis …

In Ms. H.’s case, she was idiopathic, so doctors advised that she should visit regularly every 2 months, take MRI every 6 months to evaluate and supplement vitamins of group B, Using some medicines to help relieve the symptoms of fatigue, numbness. It is necessary to limit the work that needs a lot of bending, the jobs that need sophistication in the right hand, especially the right hand. In addition, the patient needs to exercise spinal cord damage rehabilitation exercises. If the severity causes many neurological deficiencies, doctors may have to prescribe surgical intervention to draw fluid in the hollow canal to release a compression of the marrow, stopping the progression of the disease, because the empty marrow is not present. There is a radical treatment.

Currently, Thu Cuc Medical System is equipped with MRI (magnetic resonance imaging) systems in all affiliated facilities. This is considered as the “gold standard” to help detect and early detect many diseases in important organs such as the brain, abdomen, spine, joints, … this helps detect many diseases including diseases. difficult and rare cases, from which there is a way to promptly handle and intervene. In addition, the leading team of endocrine specialists in Thu Cuc will directly examine and consult interdisciplinary not to “fall” the disease and advise the best treatment for patients.
