Nathan Copeland controls a robotic arm using electrodes implanted in his brain. Published in the journal Science, the team say their work demonstrates that adding sensation to the technology significantly improves the function of prostheses for quadriplegics, compared with based solely on visual cues. Nathan Copeland, 34, told AFP: “I am the first person in the world to have a device implanted in the sensory cortex that scientists can use to stimulate my brain directly. And then, I felt like I had a real feel in my flesh and blood hand.” In 2004, Copeland was involved in a car accident that left him with a severe spinal cord injury and quadriplegia. He volunteered for scientific research and six years ago he underwent major surgery to implant tiny electrodes in his brain. Two sets of 88 electrodes the width of a human hair are arranged like tiny combs and penetrate deep into the cortex, which controls motor function. According to Associate Professor Rob Gaunt of the Department of Physical Medicine and Rehabilitation at the University of Pittsburgh, co-leader of the study, fewer than 30 people in the world have received such a transplant. What’s unique about Copeland’s case is that an additional set of electrodes is connected to his dorsal cortex, which receives and processes sensations. The idea of ​​sending haptic feedback to the tactile sensory cortex dates back decades, but doing so in a controlled and understandable way by brain circuitry used to be a major challenge. After Copeland underwent surgery to install the electrodes, the team was truly thrilled. Then came the decisive moment, when they tried sending the first tactile signal. “It felt really fuzzy,” Copeland recalls. He asked them to try again to make sure it was real. Before the interface could work with the robotic arm, the scientists had to perform a series of tests on Copeland. First, they needed to learn which electrodes cause what sensation when activated and which fingers are associated with them in order to set up the robotic hand correctly. They also made him watch a video of the robotic arm moving left or right and recorded the electrodes lighting up when he was asked to “think” it was him controlling it. Copeland sat next to a black metal robotic arm and was asked to pick up a series of small objects such as rocks and spheres and place them in a box – when the tactile sensors were turned on or off. He can complete each task in an average of twice as fast when the sensors are activated, and can even perform more complex tasks like picking up a glass and pouring its contents into a glass. another cup. The team wanted to further refine the prosthetics because they didn’t want to just do science experiments in the lab, but wanted to actually make devices that would be useful to people. Copeland has set up his brain-computer interface at home when the Covid-19 pandemic shut down universities and has used his downtime to learn how to draw on a tablet and even play video games. death. He does this by using his mind to send signals directly to the computer, instead of using his arms to press buttons.

(Photo: Internet) (Photo: Internet) Iceland belongs to the Arctic Circle, made up of volcanoes belonging to an active submarine volcanic ridge. Besides glaciers, icebergs, Iceland also has many volcanoes, hot springs and huge geothermal resources due to its location on the Atlantic volcanic belt. According to Reference, it is because there are glaciers and volcanoes together that Iceland is called the land of fire and ice. (Photo: Internet) (Photo: Internet) The center of the island is an extremely cold highland area, almost uninhabited. More than three hundred thousand Icelanders live mainly on the coast, of which nearly half are concentrated in the capital Reykjavík. The capital is more than a thousand years old and Reykjavík means Smoky Bay. (Photo: Internet) As the name suggests, this city is a bit dreamy, a bit ancient and most of the architecture is simple and small. Icelanders do not need massive buildings because the magnificent nature here is enough to make anyone overwhelmed. In addition to ice and snow specialties, there are also countless beautiful waterfalls. If you come here in the summer, the best way to explore this beautiful land is to rent a self-drive car along the Ring Road. This route has a total length of 1,322km, surrounding the island and connecting most of the main city, so of course it runs through most of the main attractions, freely roaming around. In the evening, visitors can rent a hotel or bring a tent ready for camping. (Photo: Internet) Along this road, there are many fully equipped campsites, with a kitchen for you to cook for yourself, a full bathroom and toilet. Therefore, the most economical way is to bring tents and buy ready-made food at supermarkets. Although it is summer, the temperature is still quite low, so you still need to bring some warm clothes. The weather is also quite erratic, it can rain when it’s sunny, then it’s sunny again, so you can enjoy the rainbow. There are times when sitting by the waterfall, if you are lucky, you can see a double rainbow. (Photo: Internet) (Photo: Internet) Ring Road is considered very beautiful, so even sitting in the car, you can enjoy the scenery without getting bored, turn on the music and chill. Once you come here and experience driving along the roads in Iceland, it will be an unforgettable memory of your youth.

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.

Experiencing countless times of acupuncture and acupressure, she still has not regained her feeling, she used to be discouraged and wanted to give up her life. The soft woman many nights cried and swollen eyes, feeling helpless when faced with events and pressures. But then thinking about her family, her children, she told herself that she must try to overcome her circumstances and not give in to fate. A mother of two believes that only her own efforts can bring miracles. Once led to a yoga practice center by a friend, aware of the importance and effectiveness of this practice, she decided to consider yoga as a special treatment and spent several hours practicing every day. Few people expected yoga coach Vi Salano to be a half-paralyzed girl. The series of days she first came to yoga were countless times when she shed tears in pain. The muscles at that time were still tense, not to mention exercises that were not suitable for her current health condition, which made it very difficult for her to exercise. After understanding the problem, slowly listening to her body, she prepared her own practice lesson plan. Starting from the simplest movements, when her body adjusts to her, she increases the difficulty of the exercise. “At the beginning, I was not used to it, simple movements like standing up and sitting down also made me feel nauseous and dizzy. But thinking about my health, I persevered. I actively go online to find simple exercises, listen to my body to choose the right movements “, Ms. Xuan shared. The mother of two children “transformed” spectacularly thanks to yoga and cardio exercises. Every day, she spends 1-2 hours practicing. Making use of every space, every free time, she creates a habit of movement for herself. The more she practiced, the more she began to challenge herself with beautiful postures that were as difficult as professional coaches. Practicing yoga for about 2 years, she found that her muscles had recovered and did not shrink. But it was not until the following year that she officially regained all of her feelings and felt her remarkable change. From a person moving sluggishly, sickly after a long period of being paralyzed, she now has a slim, toned and sexy body. The practice even helps her eat well, sleep more deeply, her spirit is always full of optimism and joy. Ms. Vi Salano practices yoga anytime, anywhere, challenges herself with many difficult movements and terrain. Realizing that some parts are still out of proportion, out of proportion, she both practices yoga and combines physical fitness exercises, focusing on incomplete muscle groups to make her body firmer. “Everyone’s body is not perfect, there are skewed, unbalanced positions. I myself also realize that there are still some shortcomings such as the third round is atrophy, not proportionate, so try to spend time practicing to improve ”, female coach said. She focused on practicing round 3 to adjust her balanced body. After 1 year of practice, Ms. Vi Salano surprised many people with her impressive “transforming” appearance. From a person with an unattractive physique, once guilty because of being disparaged, she has regained her sexy, balanced appearance. Waist area from 76 cm to 60, abdominal muscles toned. Even the initial 3 atrophy, deviation of only 79 cm has also been markedly improved with the current measurement of 96 cm. In addition to focusing on changing the third round, the mother of two children also pays attention to training her hands, thereby performing many impressive and professional balance postures, not inferior to famous coaches. Experiencing, changing and feeling the obvious results after a long period of practice, she also inspires many people, instructing them appropriate exercises and movements to improve their physique and shape. Health promotion. A mother of two confidently exercises balanced postures with toned hands. Currently, Ms. Vi Salano is guiding yoga both online and offline for hundreds of students in Hanoi. Classes with many different time frames, focusing on each part of the body help students make suitable choices, depending on their own needs. The experience and dedication of the 35-year-old woman received a lot of support from the trainees and the majority of people achieved positive results after the practice under her guidance. The 35-year-old woman inspires many women to learn to love themselves to change and become more confident. Up to now, Ms. Vi Salano has more than 4 years working with yoga. Not only becoming healthy, seductive, affirming her own values, but she also helped hundreds of students change both physically and mentally, infusing life energy and inspiring many people. Let’s see some other pictures of a mother of two “transformed” impressively thanks to yoga! Experiencing, changing and feeling obvious results after a long period of practice, Ms. Vi Salano also inspires many people.

Ms. Vi Salano (real name is Vi Thi Thanh Xuan), 35 years old, is currently a yoga instructor in Hanoi. Having been with yoga for more than 4 years, the great thing she has done is not only helping hundreds of practitioners change, inspire and energize them, but also in the process of “transforming” successfully herself. . Few people know that, before becoming a yoga coach, Vi Salano was once paralyzed. Due to difficult circumstances, she had to borrow from her friends every dollar for treatment. Before and after pictures of her coming to yoga. Through countless times of acupuncture, acupressure and numbness still can’t regain my feeling, I used to think life ‘that’s all over’ when so many dreams are unfinished. However, she did not succumb to her fate, especially when she was only in her twenties. Only my own efforts, she thought, can bring miracles. After that thought, she decided to go to yoga and spend a lot of time practicing. At first, the muscles are still tense, so the exercise is quite difficult. When she understands the body, she prepares her own lesson plan and performs the simplest word exercises and gradually increases the difficulty as she acclimates. Every day, she spends 1-2 hours practicing yoga. Whenever she has free time, wherever she is, she also creates a habit of movement for herself. The more she practiced, the more she began to challenge herself with beautiful and difficult poses. Having persisted for about 2 years of practicing yoga, she found that her muscles had recovered and did not shrink. But it was not until the following year that she officially regained her full feeling. Not only recovering the body, eating well and sleeping more deeply, Ms. Vi Salano has also “transformed” amazingly since yoga. From a rather plump, sluggish person, she has lost weight, regained her balanced physique. Not stopping there, she also combined to practice physical fitness exercises, focusing on incomplete muscle groups to make her body firmer. After 1 year of persistent yoga practice, Ms. Vi Salano has completely “transformed” with a balanced and sexy body. Waist area from 76cm to 60, abdominal muscles toned. Even the initial 3 atrophy, deviation of only 79cm has also been markedly improved with the current measurement of 96cm. Experiencing, changing and feeling the results after a long period of practice, this female coach also inspires many people, guiding them to practice to improve their physique and improve health. . In addition to teaching yoga, Ms. Vi Salano also opened a third round practice class for those with the same passion. Photo: FB.

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.

According to the rules posted on the website of the China Cyberspace Administration (CAC), live streamers will have to provide their real names as well as a social credit number to the livestream platforms. These identifiable information should then be forwarded to the local tax authorities. Live streamers need to be over 16 years old unless supervised by an adult. In addition, livestream platforms are required to promote monitoring of live content and to immediately handle illegal and misleading information. Ly Giai Ky is known as “the prince of lipstick” in China. Photo: Baike. Acts like promoting gambling or spoofing views are prohibited. The CAC will also establish a blacklist of frequently violated live streamers. New regulations, which started to take effect on May 25, are expected to limit the misbehavior of livestreamers, false advertising, and counterfeit goods that are rampant in the streaming industry in the country. people. Since the outbreak of the Covid-19 epidemic, online sales have grown rapidly in China. According to analytical background chyxx.com The live-stream e-commerce industry is estimated to be worth nearly 971 billion yuan ($ 149 billion) in 2020, more than double the scale of 443.8 billion yuan in 2019. In China, Alibaba’s Taobao, ByteDance’s Douyin, and Tencent-backed Kuaishou are leading live-streaming e-commerce platforms. Hundreds of thousands of people across the country are selling all kinds of goods through livestream. Famous live streamers such as “lipstick king” Ly Giai Ky and “livestream queen” Viya are capable of reaching millions of yuan in sales in just one livestream. As China’s economy has been ravaged by the pandemic, the live-streaming industry has played an active role in preventing unemployment, boosting domestic demand, and alleviating poverty. However, the industry is also showing a dark side as many consumers accuse some of the streamers of misleading products or even selling fake products. By intensifying monitoring of every aspect of livestreaming, the new regulations are crucial for regulating the Internet market and maintaining the legitimate rights and interests of consumers, CAC said.

The new poster was revealed by the crew “Override”. Photo: NSX

In the poster “teasing goods,” the hammock, the familiar peaceful image of Vietnamese countryside, suddenly becomes a devilish “net” binding Lam Thanh My little girl. The little girl’s horrified expression and the devil’s creepy face behind her caused haunting viewers.

Lam Thanh My is the face of a promising child actress on the Vietnamese big screen. At a very young age like the present, she has had a series of roles in outstanding movies, including Doat Soul (director Ham Tran), I See Yellow Flowers On Green Grass (Director Victor Vu), Tinh Dau Tho Ngay (director Tran Nhan Kien) … The pure beauty like a muse with natural acting makes Lam Thanh My a very popular name for directors as well as audience. fake favor. Back in Bong De, Lam Thanh My will bring a very different image to his previous roles. In the family where the father “rooster raising children”, the character of Lam Thanh My is not only an older sister but also a mother who always takes care of and protects her little sister. Also suffering from an obsession from the past, the sister played by Lam Thanh My will show her mature, tough on the outside to hide her wounds as well as her inner bruises. This is a role that requires the ability to express complex emotions as well as concentration and deep understanding of the character.

“Sleep Sleep” is the first Vietnamese horror film to exploit the phenomenon of sleep paralysis – a phenomenon that is still controversial until now. Although there are scientific explanations about paralysis, in Vietnamese culture, it is still a phenomenon associated with many spiritual factors. Along with the Vietnamese village context and familiar items in everyday life, “Sleep Sleeper” will be a novel and haunting horror work. Not too abusive jumpscare or gore scenes, the movie will still make viewers shiver and fear during the enjoyment. “Sleep Sleep” is expected to open from May 14, 2021.

“The Sleeper” director Le Van Kiet graduated with a degree in Film and Television from the University of California, Los Angeles (USA). He has debuted movies: The House in the Alley 2012), Gentle (2014) … In 2019, he collaborated with Ngo Thanh Van on the action film Hai Phuong – about a mother who went to save her arrested daughter toads. Launched in Vietnam from February 2019, the work has caused box office fever with action elements. The work became the highest-grossing Vietnamese film of all time – over 200 billion VND (including international markets). The film is also shown in the US, China and the Netflix system under the name Furie. On Rotten Tomatoes, 95% of critics rated the film positively.

It costs hundreds of millions for the flower pots

Mr. Ngo Van Tuan (29 years old, Hoa Binh city) confided that the whole family passed away Tet just because he was hospitalized.

On the 29th of Tet, after the couple went to Tet market, they bought a peach tree. Gleefully brought out the peaches to pour out the soil and then Mr. Tuan carried the pots and put them in the house. Due to the small peach pot, he was subjective.

When just stooped, trying hard to hold the pelvis, I heard a cracking sound in the back, from which the entire spine was throbbing, the lower limbs were numb. Mr. Tuan could not sit up but lay on the floor, at that time the feeling of turning was also difficult. Burning skin, feeling like there are thousands or thousands of needles piercing the skin.

His family rushed to the hospital but could not sit, so they called an ambulance to carry a stretcher to the hospital. After pain relief treatment, the doctor reported that he had an acute disc herniation. Hearing disc herniation afraid of affecting the ability to walk later, Mr. Tuan and his wife rushed to Hanoi for treatment. After Tet, the acute stage was over, but because the herniation was too large, the doctor decided to operate.

Mr. Tuan said that just because of the calf flower pots, so far, the total cost of treatment has lost more than 100 million dong, not to mention the damage to health.

Illustration.

Not only Mr. Tuan, who is receiving rehabilitation treatment due to herniated disc, Nguyen Thuy Dieu (31 years old, Cau Giay, Hanoi) is also struggling with this disease. Last year, Mrs. Dieu said that when she washed the blankets, when she lifted the blanket to put it in the washing machine, she felt a sharp pain in her back. Then the pain gets worse and worse, standing up straight is also difficult. Ms. Dieu goes for pain relief treatment and is still suffering because her back is so painful, walking is also suffering.

Many bad habits young people have

Master, doctor Tran Quoc Khanh – Vietnam Duc Friendship Hospital Hanoi, said disc herniation is one of the most common spinal diseases today and tends to be more and more rejuvenated. In particular, young people are subjective with their own spine, there are many bad habits that affect it.

According to Master Khanh, most young people are admitted to the hospital after suddenly lifting heavy loads such as carrying containers and pot plants. When calves need to lift slowly, people often have a habit of bending over and lifting suddenly causing acute disc herniation. There are many patients who have to lie down in one place after calving the pot, their back and right leg down for emergency surgery.

In the case of a patient like Mr. Tuan, when the hernia is performed after sudden exertion, the hernia block is very large, so the patient has to operate early to avoid limb atrophy.

Occupations such as nail care, driving, watch repair are jobs where people often have spinal problems, including disc herniation.

In addition, some people gain excess weight, the heaviest pressure on the disc is the back when bending, arching, twisting, and jumping, so it is easy to have disc herniation.

Vietnamese people are fat pear shaped (belly fat), focus on forward, so the right spine arched forward is also the cause of disc herniation.

Bad habits in life are also prone to disc herniation such as smoking, sitting for a long time. Sitting at work for long periods of time, continuously crouching the disc in the damaged back and herniation easier than others.

When there are signs of pain in the spine, in the neck, the pain spreads to the shoulder, back, the thoracic spine … lasts about 1 week, the patient needs to be examined. If disc herniation is not treated in time, the patient can only lie still, unable to sit up or is paralyzed, disabled for life.

Therefore, whenever the above symptoms appear, people need to go to specialized medical facilities soon for early examination and treatment.

To prevent disc herniation, when carrying, should not exert effort. Spine can be moved before carrying heavy objects, calf in a straight-back position without stooping, those with a history of back pain should give up the habit of carrying something.

The effects of deer antler are studied very early on and there are many works that prove it is very beneficial for health. Deer antler is one of the 4 pharmaceuticals (velvet, ginseng, cinnamon, side) that have the leading effect of complementing, prevention and healing for humans.

Products from deer and deer used in medicine include: velvet: young horns used fresh or dried; reindeer – deer antlers: old horns; high sense (delivery) – high ban long: high densely cooked from old horns; dewy reindeer: antlers after cooking banlong (China, Vietnam) or black-burning deer antlers and small canes (Japan).

The flavors are taken from stellar deer (Cervus nippon Temminek.), horse deer (C. elephus L.) or deer (C. unicolor Cuv.), family of deer: Cervidae.

In terms of chemical composition, deer antler contains many inors, organic substances, fats, amino acids, catalaza enzymes, peroxydaza, male and female sex hormones (cholesterin, progestron, oestron and testosteron). The scientist Pablenko (USSR) extracted the hormone pantocrin (elk velvet) from Siberian deer antler.
