“Mass production has begun. It’s no longer a test, it’s a robot that can appear in sci-fi movies because of its ability to fight independently. It’s exactly the weapon. of the future,” emphasized Sergei Shoigu. Russian Defense Minister Sergei Shoigu talks about the country’s military priorities. Photo: TASS. According to Sergei Shiogu, equipping the armed forces with such means is one of the top priorities. And Moscow has a lot of work to do to expand its line of complex, military-purpose robots. Many military experts estimate that, although Russia’s military budget is not as much as that of the US or the European Union (EU), the country has spent a great deal of it on “sharpening knives”. Earlier, the Russian Ministry of Defense said that the first unit with attack robots will be formed in the Russian armed forces to operate five robotic systems “Uranus-9” with 20 combat vehicles. Offensive and defensive strategies will be studied in a Department of Defense science center. An experimental Russian attack robot. Photo: Sohu. It is known that the Uranus-9 is a multifunctional combat platform developed by Russia’s 766 Technical Equipment Production Bureau, with a total weight of 10 tons, 4.5 m in length, 2 m in width, 1 in height. ,4 m and maximum travel speed is 40 km/h. This combat robot combines powerful firepower, is equipped with a comprehensive controlled weapon system including 4 9S120 “Bumblebee-M” anti-tank missiles, 4 9K33 SA-18 anti-aircraft missiles and 1 2A72 cannon 30mm caliber with 200 rounds ammunition and 7.62mm machine gun mounted on the vehicle. In theory, its anti-tank missile has a range of 5,800 meters, enough to threaten today’s major armored targets.

(Photo: Internet) This majestic waterfall is named after the Honokohau River – a long river that flows from the top of Puu Kukui, which receives annual rainfall of up to 9,000 mm, also the area is said to have the highest rainfall. world. Since the Honokohau waterfall has two levels, the water can be seen pouring inside into a small depression and sinking several hundred meters deep, flowing to another “natural pool” at the bottom of the mountain. (Photo: Internet) (Photo: Internet) The beautiful natural scenery here has appeared in the movie Jurassic Park , making many more passionate about this victory. With such a view, Honokohau Falls is a must-see when visiting Hawaii. (Photo: Internet) It looks so beautiful and majestic, however, coming here is not convenient. This waterfall has never been conquered by anyone, because of its incredible height and steep terrain. This waterfall cannot be reached by car or hiking, the only way to see this amazing natural wonder is by helicopter. (Photo: Internet) Sightseeing also depends on the weather because this area often receives rain, or sometimes the whole waterfall is covered by a sea of ​​clouds. So it’s best to check the weather before scheduling this scenic tour. (Photo: Internet) (Photo: Internet)

The origin of the Darvaza crater remains controversial, but the most widely accepted theory involves a Soviet expedition to explore for gas. (Photo: Internet) According to the Daily Mail, in 1971, Soviet experts drilled and dug the area and reached a large cave filled with natural gas. Unfortunately, however, the ground beneath the part being dug collapsed, creating a huge hole with a diameter of 70 meters. Concerned that the pit would lead to a toxic gas leak, the experts decided to burn it. And as a result, the amount of gas below is so abundant, that the fire in the pit keeps burning forever. It has been burning for 50 years now. (Photo: Internet) George Kourounis, a Canadian explorer, became the first known person to venture down into the pit’s interior. Footage of his expedition was first broadcast on National Geographic, which partially funded the trip. The aim is to collect soil samples from the bottom of the pit, and try to determine if life can survive in such a harsh environment. (Photo: Internet) Kourounis shared: “ The story behind how the hole was born is still a mystery, and there is no place like it on Earth. It is very unique. ” Despite being the most popular tourist attraction in Turkmenistan, the Darvaza fire pit has always kept its pristine and quiet appearance because this place is so remote and far away from traffic. The number of tourists visiting this country has been small, and it is not easy to get here. (Photo: Internet) If you go by private car, it takes nearly 4 hours to get there. For those who travel alone, they have to take a public bus, then find a car rental or walk 7-8 km to Darvaza which takes at least 6-7 hours. The red-orange fire pan appears more and more brilliant and fanciful against the background of the sky, which gradually changes from pink to purple, to blue, to black. Visitors here are eager to capture every moment of nature. A giant fire well that shines brighter and brighter in the middle of the vast, dark desert, a lonely but fierce beauty that makes anyone who sees it overwhelmed. (Photo: Internet) (Photo: Internet) Coming here the previous afternoon and leaving the next morning, visitors will admire all the wonderful moments at Hell’s Gate: an enchanting purple sunset, a magical moonlit night and a radiant morning. pristine.

According to Business Insider, a video clip recently released by Gravity Industries (UK) shows soldiers of the Royal Marines wearing a Jet Suit personal jet produced by this company. disembarking from the speedboat, ascending, and rapidly landing on the deck of the Royal Navy’s offshore patrol vessel HMS Tamar. In the video, British soldiers fly easily over the sea like the superhero character Iron Man (Iron Man) in the famous Hollywood movie of the same name. The Jet Suit personal jet suit helps the wearer move easily through the air. Photo: CNN The exercise was conducted to explore how to land on ships as an alternative to the traditional method. In a statement, the Royal Navy said the Royal Marines used the Jet Suit to practice the “visit, board, search and capture” (VBSS) operation. VBSS is considered one of the most complex and dangerous sea missions. Traditionally, soldiers would use speedboats to approach warships and use rope ladders to climb or conduct landings from helicopters with the support of snipers and drones. Both of these methods require a lot of time to prepare the means. Meanwhile, with a personal jet suit, a soldier can fly up from a speedboat, land on a ship and then release a rope ladder for teammates to climb onto the ship. The images in the video clip show the Jet Suit’s ability to support soldiers on landing missions on board ships. “The Jet Suit provides extremely rapid access to any area of ​​the target ship, making it convenient for soldiers to carry weapons and easily move or retreat,” said Gravity Industries. . This is a tactical revolution for many special forces and can be applied more widely than just landing on ships.” With an operation time of 8 minutes, the Jet Suit personal jet made by Gravity Industries is equipped with 5 mini jet engines, including 4 engines attached to the arms and one on the back. Thanks to this design, the user can easily adjust the flight direction as desired. After wearing the Jet Suit, the user can fly at speeds up to 88km/h. This technology is a big step forward in making scenes from sci-fi movies come to life. British inventor Richard Browning, founder of Gravity Industries and a former member of the British Royal Marines, has worn Jet Suits to show the world many times and has been dubbed “Real-life Iron Man real”. Commenting on the Moskovsky Komsomolets newspaper, Russian military expert Vladimir Gundarov said that, like the supporting skeleton or invisibility cloak, personal jet suits will not be widely used in military units. . “All special equipment will be provided to the special forces and can be used in an emergency,” said Vladimir Gundarov. Besides the obvious advantages, Boris Gundarov said that personal jet suits also have disadvantages such as the lack of stealth, jet engines emitting a lot of noise and emitting a lot of heat. A person flying in the air with a personal jet suit is an easy target for any weapon, the expert notes. It is not clear how effective the Jet Suit will be if used on the battlefield, but it is clear that this personal jet suit will need to be improved to overcome some disadvantages that can endanger soldiers. as well as extending the operation time to match combat operations.

Cryogenic technology and the promise of bringing the dead back to life (Photo: Internet) Cryogenics, also known as cryopreservation, is the technique of freezing a dead body or body parts to protect them from decomposition. Proponents of cryogenics see it as a magical technology to bypass death and even reach immortality. They decided to freeze and preserve the body intact, hoping to wait until science developed enough to revive the dead body and cure whatever caused them to die before. . (Photo: Internet) To date, more than 350 dead people worldwide have been preserved at low temperatures at one of four facilities providing this service: two in the US (Alcor Life Extension Foundation, Arizona and Cryonics Institute, Michigan State); 1 in Russia (KrioRus company), and 1 in Portugal (also Alcor lab). About 1,000 people have signed up for the post-mortem resurrection service. In this list, there are famous figures such as Britney Spears, Simon Cowell, Larry King, Don Laughlin (a gambling business magnate in the US) or director Charles Matthau… How are cryogenics performed? Legally, deep freezing is only performed when the patient is dead. The ideal time to start a cryogenics procedure is about 2 minutes after the patient’s heart stops and no more than 15 minutes afterward. First, the body is gradually cooled with ice and injected with chemicals to reduce clotting. After the temperature drops to near 0°C, blood is drawn to be replaced with a solution intended to protect tissues and organs. (Photo: Internet) The technicians also injected the body with another solution to prevent ice crystals from forming, then continued to cool the body down to -130°C. As a final step, the body is moved to a container of liquid nitrogen. There, it will be cooled down to -196°C. Cost of cryogenics The fee that a person has to pay if they want to deep freeze the whole body at the Cryonics Institute is from about 35,000 USD (about 800 million VND). While if you do the procedure at KrioRus in Russia, it will cost you 37,600 USD (about 860 million VND). At Alcor, the cost of preserving a person is 220,000 USD (equivalent to 5 billion VND), if you want to save more, just preserve the brain for about 80,000 USD (approximately 1.8 billion VND). This cost does not include the annual maintenance fee, which means that the longer you keep it, the more money you have to spend. (Photo: Internet) chances of success Many scientists believe that the chance to revive a dead person is almost zero. Because the body’s organs, especially vital organs such as the heart, lungs, brain, and kidneys, must have been damaged when freeze. Until now, the damage that has occurred and resulted in death is irreversible. Due to the severe damage to internal organs and the brain, the law requires technical participants to be scientifically dead, which makes it almost impossible to revive a dead person. (Photo: Internet) Alcor doesn’t offer a clear technique to resurrect someone who’s been dead too long, or a technique under development in the future to bring the dead back to life. A very vague technology on Alcor’s website is described that they will use molecular nanotechnology with microscopic nano-sized robots that can replace damaged chromosomes and can restore individual cells. . It is worth mentioning that Alcor has not researched this technology, in fact they only trade in freezing and preserving the dead and no one is responsible for the patient’s promise to revive. Alcor’s main research is only on techniques to preserve the dead as best as possible. The prospect of resurrecting a frozen body has so far been quite remote and unrealistic. And many in the scientific community even consider this to be unethical.

Fatima and one of his inventions. Building robots when you are 10 years old It all started when Fatima was 10 years old and created the first robot capable of taking pictures. She then quickly developed 12 other inventions, including solar charging bags for devices, robots that can replace sick students to school, power belts for the hearing impaired and intelligent steering systems. Block people from texting while driving. Now Fatima turns 18 and is a student in computer engineering at Virginia Polytechnic (USA). She has become an inspiration, paving the way for other women and girls to pursue innovation and STEM (science, technology, engineering and math). From a young age, Fatima was passionate about science and invention. She enjoys watching science fiction, documentary and technology shows. In addition, her parents have a technical background, which contributes to her passion for science and invention. “I was influenced a lot by the shows I watched, mainly about science. However, my living environment also has a lot of impact, including that my parents are engineers … all contributed to my hobby and personality, “said Fatima. The family plays a very supportive role for Fatima. At home, her parents help her and teach how to do small projects. Over time, Fatima became proficient with the skills and was able to enter the industry with the guidance and help of her parents. Overcoming challenges At the age of 7, Fatima is excited to learn about new industries and build exciting projects. However, over time, Fatima realized that it was very difficult to stay in the industry as a young girl. “There aren’t many opportunities and when I try to take the opportunities, people don’t take me seriously or think it’s just a temporary period and think I’ll find another job that is gender-appropriate. to me, ”Fatima said. However, over the years, Fatima said it is very happy to see the change in the gender gap that women have always suffered. “Today, there are a lot of resources that young children, especially girls, can use to educate themselves and build their own skill sets. In addition, the society is more advanced than the ideology of sexism and more open to women and girls in the field of technology, “Fatima said. The UAE’s youngest Inventor title reinforces Fatima’s progress. “It opened many doors for me and allowed me to grow as an inventor, helping me gain some validation in places where I was deemed unsuitable, even if it came with very much. many responsibilities. I am very honored to carry that title. Getting support and recognition from the government is one of the highlights of my journey ”. Fatima received the UAE Youngest Inventor Award. Inspire the younger generation Fatima is not the first female scientist and not the last to talk about it. The UAE government has made a great effort to encourage women in the field of science and technology. A 2018 Times Higher Education report states that more female students enroll in STEM than men in the UAE. The reason is attributed to the fact that the government empowers women through policies, the opportunity to ensure that female role models are included in science textbooks. Fatima said she is looking forward to the time when the title will be awarded to another ambitious inventor. For young inventors, she was determined to do all she could. She praised the companies that initiated CSR (corporate social responsibility) activities in providing young students a platform to explore more opportunities in the STEM industry. So when air-conditioning solutions provider Taqeef launched a 2020 version of the STEM iMatter curriculum, Fatima knew this was what she needed to be involved with. Designed to help students put theory into practice and familiarize themselves with the role of STEM in their future work, iMatter assigns students to find solutions to real-world climate problems. “The show has some of the brightest young brains with great ideas,” says Fatima. I took the opportunity to become a speaker at their event. I was delighted to hear that they enjoyed my speech and learned something from it. I was even happy to receive some feedback videos sharing participants’ experiences, insights and gratitude ”. Fatima said that programs like iMatter have created conditions for more students to experience STEM learning. If governments, business and society join hands to develop STEM education and embrace more opportunities, a huge difference will inevitably emerge and more scientists, innovators and entrepreneurs. next time. In addition to her studies, Fatima said, she is focusing on patenting some of her new ideas. “I hope to get masters and PhD degrees in artificial intelligence (AI). I aim to set up my own AI company in the future and become a professor in this field ”. Fatima affirms that the invention idea is very simple and anyone can do it every day in their life. What she sees as important right now is to foster gender segregation, engage girls and women in STEM, and provide them with an environment for growth.

Advantages: New and unique experience. Defect: Difficult to control, the cost is quite high. Parasailing – Parasailing canoes Canoeing is known to be one of the most exciting adventure sports in the sea. When participating in the game, visitors are fixed to a parachute, after the canoe runs to the sea at high speed, the parachute will fly high. Enjoy the vast sea air from above. Photo: Foreverwithcole. It is called an adventure game but the parasailing ensures safety for the participant with a sturdy seat belt system, in addition to a life jacket and a support canoe underneath. Join the game, visitors do not need to go through a familiarization course, just wait for the wind to pull you up, enjoy a vast sky. However, before flying, the instructor will guide visitors on some notes when flying to avoid the dangers of high altitude. In case visitors are not confident can fly with friends, and the coach is always ready to accompany when needed. Cost fluctuation: 500,000 – 800,000 VND / round Advantages: Experience a feeling of refreshing, interesting, does not take time to get used to, less dangerous. Defect: Not suitable for people with fear of heights.

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.
