If it is in South Asia, it may be even more difficult, because it is located in the tropics, and the temperature often reaches 50 degrees. Today’s India is a typical example. Anyone familiar with the local national conditions should know that the gap between the rich and the poor in this country is very large. There are only a few rich people who can use air conditioners. As for the poor, they can only find ways to escape the heat, such as buying ice cubes and soaking them in the Ganges water, or making simple straw air conditioners.

With the development of time, a kind of heat-reducing delicacy “watermelon pie” has also been born in the local area. This summer-specific fruit is extremely popular in many countries. India is no exception. Local vendors often treat They are cut into pieces and placed on the street for sale. People passing by also like to buy them and eat them, but for foreign tourists, they may be a bit repellent. What is going on?

In fact, anyone who has traveled to this country should know that the environment in India is very dirty, messy and poor. There are a lot of garbage piled on the roadside. Because of religious beliefs, people will not go to the bathroom at home, but will urinate and defecate outdoors. The Shanghui is full of unpleasant smells, and flies are flying everywhere, and these street foods will naturally suffer. In addition, the materials are not very hygienic, and diarrhea will inevitably occur after eating. The same is true for watermelon pie. In addition, because there is no good preservation technology, they are placed on the street carelessly, and dust and flies are allowed to fall on the top. Even if the price is cheaper, it will inevitably make people feel somewhat acceptable. No, it’s not just watermelon, like popsicle sugar cane juice, it also uses Ganges water, so don’t try it lightly for the sake of your stomach. Do you feel that you have gained knowledge when you see this? So what do you want to say about this? Welcome to leave a comment below!

F-20 leads military industry stocks to take off

As the two centuries of the founding of the party and the army are approaching, there will be more catalysts for the defense and military industry, and “a hundred years of change” will inevitably accelerate the modernization of our army. Last weekend, CCTV’s military channel reported that the second unit equipped with the J-20 was officially made public. It was the first group of the Air Force to form, participate in the war, and win the first “Strong Army Pioneer Brigade”. Compared with the J-20 equipped by the “Wang Hai Brigade”, the J-20 equipped by the “Strong Army Pioneer Brigade” has undergone many improvements, especially the engine is replaced with a domestic turbofan-10 engine, which means that the J-20 has been realized. Fully localized.

Affected by this news, the national defense and military industry sector rose heavily in early trading today. The sector index rose for the third consecutive day and hit a new high in nearly three and a half months. Dongtu Technology’s 20% daily limit, Eleda, Bright, and New Research , Anhui Technology, etc., the daily limit may rise by more than 10%. Military ETF funds also rose today, leading the rise.

The F-20 can achieve 100% localization rate, even if it is not easy in the world, except for the F-20, currently only the United States can achieve 100% localization of the fifth-generation fighter, even Russia and France currently Russia lacks high-performance electronic equipment and optical equipment, and needs to import gallium arsenide semiconductor materials from South Korea. Although France can develop Rafale fighters, France does not have the technology to manufacture ejection seats and needs to import ejection seats from the United Kingdom. chair.

Ai Leda focuses on the field of aviation manufacturing, mainly engaged in the production of aircraft structural parts and engine parts. Since the establishment of the company for more than ten years, it has accumulatively participated in the development and production of a variety of models involving more than 3000 aviation parts. On the investor interactive platform, investors have repeatedly asked whether the company’s products are available for the F-20, H-20, and Yun-20 models. Eleda did not respond directly on the grounds that military secrets were involved.

But this does not prevent investors from showing their love for Philharmonic. In 2020, Philharmonic has soared by 271%, and it has risen by more than 30% this year. Today, stimulated by the good news, the intraday straight line pulled up to the 20% daily limit. Beijing Capital Capital increased its holdings of Philharmonic by more than 50% last Friday, and its number of shares hit a four-month high.

Guohai Securities stated that the continuous installation of the J-20 aircraft will further enhance the air force’s comprehensive combat capabilities, and also shows that the national defense construction continues to advance, downstream demand is strong, and the aviation industry chain continues to rise. The 14th Five-Year Plan period is a critical period for achieving the “Hundred Years of Military Struggle” in 2027. The military industry has entered a period of accelerated growth, the industry’s production capacity is expanding, and the fundamentals of many high-quality segments will continue to improve. It is recommended to focus on such fields as missiles, military aircraft and aero-engine industrial chains, new materials for military industry with high upstream prosperity, military electronics, and military information technology.

Capital rallies to reduce chip stocks

Electronic technology stocks continued to strengthen in early trading. The semiconductor sector index hit a record high during the session, the gallium nitride sector index also hit a record high, the chip sector index hit a new high in the past year, and the lithography machine sector index approached a new high this year. The daily limit of Liyuan Information is 20%, and the daily limit of Hanwei Technology, Jingsheng Electromechanical, and Jingchen shares may rise by more than 10%.

As the problem of chip shortages continues to intensify, major domestic and foreign semiconductor manufacturing companies have raised their capital expenditure plans, vigorously expanding production capacity, and increasing prices, shortages, and expansion into “high-frequency vocabulary.” Domestic and foreign companies have raised prices in various aspects of semiconductors, but the contradiction between chip supply and demand is still prominent, which is eventually transmitted to the production links of physical enterprises such as automobiles and mobile phones. The market predicts that this round of the semiconductor industry boom cycle will last at least until the end of 2022.

However, investors should focus on the fact that at present, experts have warned that chip manufacturers may have excessive hunger marketing and large-scale production expansion, and there may be a crisis of chip surplus in the future. And market capital is also constantly flowing out taking advantage of the stock price surge. According to Wind statistics, starting from Qunengdi, the National Integrated Circuit Industry Investment Fund has successively reduced its holdings in high-quality companies such as North China Chuangchuang and Zhaoyi Innovation. Recently, Weir shares and others have also announced information on shareholder reductions. In addition, in just four trading days last week, the net outflow of chips and semiconductor-related ETFs reached nearly 5 billion yuan.

Beijing Capital Securities stated that the global core shortage has allowed the industry and capital markets to re-understand the semiconductor manufacturing process, especially semiconductor foundries and IDM-mode semiconductor manufacturers. Companies with fabs will have greater and greater say in future development, and the higher the differentiation, the better, and the valuation given by the capital market will also become higher and higher. Semiconductor is the core technology. To buy a technology company, you must have technical strength, and be able to continuously launch new products, and new products can be recognized by the market to bring income.

Cross-border “drinking” Zhongxing Fungus Industry Daily Limit

How hot the liquor industry is, companies that grow edible fungi must also acquire liquor assets.

On the evening of June 20, Zhongxing Fungus Industry (002772) announced that in order to promote the development of the company’s dual main businesses and increase new profit growth points, the company plans to acquire Liu Jian and Liu Liangyue’s Shengjiao Wine in Maotai Town, Guizhou, in cash. Industry Co., Ltd. (referred to as “Shengjiao Wine Industry”) 100% equity.

Zhongxing Fungus Industry is a modern agricultural enterprise specializing in the research and development, factory cultivation and sales of edible fungi. The main products are Flammulina velutipes and Agaricus bisporus fresh products. Judging from the current main business layout, Zhongxing Fungi is determined to “drink” across the border. Zhongxing Fungus is not the first company to be the first Zhongshengjiao Wine Company.

In October last year, *ST Garden City announced that it planned to acquire 100% equity of Shengjiao Winery and raise matching funds by issuing shares and paying cash. Subsequently, the restructuring inquiry letter from the Shanghai Stock Exchange followed one after another. The core question was to explain the reason for the sharp increase in the performance of Shengjiao Wine Industry.

One month later, in November last year, *ST Park City stated that the transaction company and the target party could not reach an agreement on the valuation of the target company and terminated the acquisition of 100% of the shares of Shengjiao Wine Industry.

It is worth mentioning that in the four trading days from June 15th to 18th, the stock price of Zhongxing Fungi Industry rose successively, with a cumulative increase of 12.16% in the interval. A person in the liquor industry believes that cases of cross-border liquor making in the capital market are not uncommon, but there are many losers. There is still some suspense whether the acquisition plan can be successfully completed. The company also reminded investors in the announcement that the equity purchase agreement has not been formally signed, and it is not yet possible to predict the impact on the company’s operating results.

These days, the road surface temperature is very high, especially on roads without perennial trees such as Nguyen Chi Thanh, Truong Chinh, Trang Tien streets… the temperature always fluctuates from 40 – 50 degrees Celsius. In order to escape the “burning” heat, many passers-by have chosen the route to go through some streets with shady trees. Walking under these ancient tree-lined streets, it is possible to find some fresh and cool air in a series of horrible suffocating days. The line of beautiful, straight black star trees on Lo Duc Street brings a feeling of closeness to nature and shade for the whole neighborhood on hot summer days. Ly Dao Thanh Street has two rows of old trees that always give shade to the road surface. Phan Dinh Phung Street has rows of ancient green crocodiles. Summer comes, the whole street is immersed in a cool space under thick foliage, making it difficult for the midday sun to penetrate. The temperature recorded at noon time on streets with many old trees was much lower than the temperature measured at the same time on roads without trees. The shady tree line helps pedestrians to somewhat reduce the “burning skin” heat. People with bare heads, walk on Phan Dinh Phung street at noon without fear of the sun. The shade of green trees on Tran Phu street not only creates a beautiful landscape but also becomes a “shield” on hot Hanoi days. The green canopy blocks the sun, helps to regulate the air, and combats the stuffiness of harsh summer weather.

1. Which river is the hottest in the world? Icon Boiling River Icon Congo River Icon Nile River The correct answer is answer A: According to the Telegraph, the Boiling River, located deep in the Amazon rainforest, is the hottest river in the world. Locals call the river “Shanay-timpishka”, which means “boiling with the heat of the Sun”. The Boiling River is about 25 m wide and 6 m deep but only extends for about 6.4 km. The river water temperature always fluctuates from 50 to 90 degrees Celsius, sometimes up to 100 degrees, enough to cause anyone who touches it even for a few seconds to get 3rd degree burns. 2. In which country is the Boiling River located? Icon Colombia Icon Peru Icon Ecuador The correct answer is answer B: Peru, officially the Republic of Peru, is located in South America, bordered to the north by Ecuador and Colombia, to the east by Brazil, to the southeast by Bolivia, to the south by Chile and to the west by Peru. is the Pacific Ocean. The national area is about 1,285,000 square kilometers, the population is more than 32.6 million, the capital is Lima. In 2011, scientist Andrés Ruzo witnessed this river with his own eyes. Mirror reports that Mr. Ruzo has heard from him about Shanay-timpishka since he was 12 years old. According to what is said, the river was discovered by the Spaniards when they were deep in the forest looking for gold. Some of the people on the way back said that this land was dangerous, filled with poisonous water, man-eating snakes, hunger and thirst, disease, a river boiling from the bottom. He was later told by his aunt that he had seen the river. Originally studying for a PhD in geology at Southern Methodist University, Ruzo was really curious about this river. He consulted with colleagues at school, oil, gas and mining companies, all suggesting that the river is not real because the boiling rivers and lakes in the world often have a relationship with volcanoes. While the Amazon has almost no sign of any volcanoes. Despite all the disproved theories, Ruzo still decided to go deep into the forest and track down the location of the river that had cured the Ashaninka people in Mayantuyacu. The boiling river seemed to be out of the world, but Ruzo discovered it. He wrote a book about this river in 2016 called The Boiling River, Adventure and Discovery in the Amazon (roughly translated as Boiling River, adventure and discovery in the Amazon jungle) in the hope that the book will draw public attention to the real natural wonder and care to protect it against the growing threat from illegal logging. 3. Where is the hottest place on Earth with the temperature like walking on a baking pan? Icon Dasht-e Lut . Desert Icon Sahara Desert Icon Kalahari Desert The correct answer is answer A: According to Oddity Central (UK), the Dasht-e Lut desert, Persian for “empty plain”, is a large salt desert. Scientists believe that this desert region known as the “fire pan” of the Earth was formed on the seabed. Millions of years ago, the tectonic change of the sea floor rose, the water also gradually evaporated due to the increased temperature. Today, Dasht-e Lut becomes a barren land with an area of ​​​​about 51,800 km, surrounded by mountains on all sides. This prevented moist air from the Mediterranean and Arabian Seas from entering the desert, contributing to the record-breaking temperatures. The medium-resolution imaging spectrometer installed on NASA’s Aqua satellite conducted global surveys between 2003 and 2010. Collected data Data collected shows that the highest temperature ever recorded in Dasht-e Lut was 70.7 degrees Celsius in 2005. According to satellite data, this Iranian desert has the highest annual temperature in 5-7. 4. Which of the following lakes boil all year round? Icon Lake in the island of Dominica, Caribbean Icon Lake Kivu, Rwanda, Africa Icon Lake Karachay, Russia The correct answer is answer A: This is a boiling lake, located in the national park of the island of Dominica, Caribbean. This lake is 61m wide, 59m deep, the water is grayish blue. The temperature at the edge of this lake reaches about 82-92 degrees Celsius, the lake surface is often covered with a layer of white mist. Many people are curious why this lake is boiling all year round. The reason is that at the bottom of the lake there is a fountain, it can spray out many different gases such as carbon dioxide, sulfur dioxide… These gases can create bubbles up to 2-3m high, looks like the lake is boiling. In fact, the most terrible thing about this lake is not the temperature but the toxic gas. The plants and animals around the lake were greatly affected. Most of the factories have gone bankrupt and the surrounding area is uninhabited. 5. Which of the following lakes is likened to an “invisible killer lake”? Icon Lake Kivu, Rwanda, Africa Icon Blue Lagoon, Iceland Icon Lake Karachay, Russia The correct answer is answer C: This lake looks beautiful from afar, but there isn’t any living creature inside. The lake looks very peaceful, quiet, looks like an ordinary lake, even more beautiful when the water is very clear, reflecting the blue sky and white clouds on the lake surface. The lake is only beautiful when viewed from a distance because the lake is full of poison underneath. If you stand near the lake for 1 hour, people will die of poisoning. Therefore, this lake is also known as “the invisible killer lake”. 6. Where is the hottest place on earth where human life exists? Icon Dallol Icon Valley of Death Icon Death Valley The correct answer is A: Dallol is the hottest place on earth, but still inhabited by the Afar people, a nomadic tribe living in portable huts. Dallol is located in the Danakil Desert Basin, a remote area in northern Ethiopia, bordering Eritrea. This is a very remote and least explored place in the world. In addition to the heat from the sun, Dallol is also subjected to heat from hot sulfur and lava lakes, making the average annual temperature here always at 34.4 degrees Celsius. 7. Where is the hottest surface temperature on Earth? Icon Dead valley Icon Lut Desert The correct answer is answer B: New research into the highest surface temperatures on Earth reveals that the Lut Desert in Iran and the Sonoran Desert in North America are hotter than Death Valley in the US. The Lut Desert holds the top spot for the world’s highest ground temperature. From 2002 to 2019, this sandy area regularly hit the highest temperature threshold, likely due to its location among the mountains, causing hot air to be trapped above the dunes, especially in areas including covered with black volcanic rock. The new findings are in line with research published in 2011 that concluded the Lut desert is one of the hottest spots on Earth. From 2004 to 2007 and 2009, the Lut Desert experienced the highest surface temperature on the planet. In 2005, preliminary data showed that the area had a temperature of up to 70.7 degrees Celsius, although the new study authors say the estimate is likely to be lower than reality. From that initial analysis, NASA announced a new version of satellite software, allowing for more accurate determination of the ground temperature on Earth. Using the updated version, the researchers were able to conclude that the temperature in the Lut Desert was in fact 10 degrees higher than previously thought. The Sonoran Desert, which lies on the border between the United States and Mexico, is similarly hot, although not as hot as the Lut desert often. The desert’s low altitude means the air is less likely to rise and cool. Result Please work harder! point

Dry landscape in a field in the town of Walgett, Australia. Photo: AFP/VNA Ms. Mami Mizutori, the UN Secretary-General’s special representative for disaster risk reduction, said that drought risks becoming the next great disaster and there is no cure. A United Nations report released on June 17 found that drought caused at least $124 billion in economic losses and affected more than 1.5 billion people between 1998 and 2017. United Nations, now that global warming has increased droughts in Southern Europe and West Africa and the number of victims will “increase significantly” unless the world acts, Ms. Mizutori said. Some 130 countries could face a major drought risk this century under the UN high-emissions scenario, another 23 would face water shortages because of population growth, and 38 countries are affected by both factors. Ms. Mizutori likens drought to a virus – which tends to be long-lasting, has a wide geographic range and causes severe damage. Countries are not affected by drought but are still affected indirectly through food insecurity and rising food prices.” The United Nations forecasts that droughts will be more frequent and severe in most of Africa, Central and South America, Central Asia, South Australia, Southern Europe, Mexico and the United States. More than 40% of European Union (EU) agricultural imports could be “vulnerable” to drought by mid-century due to climate change, according to a study published in Nature Communications in the journal Nature Communications. this week.

Bath time is just a personal decision. Whether bathing in the morning or at night, the use of poor quality products will still destroy the skin. Bath time is always a controversial topic. While many people love to shower in the morning, others find it more pleasant to have a cleanse before bed. However, for dermatologists, bathing properly impacts skin health more. Water temperature Taking a hot bath is a method that helps many people relieve stress. However, for people with dry skin, exposure to hot water does more harm than good. Water temperature is an important factor to pay attention to when bathing. Photo: Scooper. Dermatologist Ivy Lee (Los Angeles, USA) said that the relaxation factor makes many people decide to take longer baths. But this habit can dehydrate the skin. Besides, Ivy Lee and some dermatologists recommend bathing for less than 10 minutes. You can use lukewarm water or cold water to avoid dry skin. Meanwhile, Phyllis Zee – a professor of Feinberg School of Medicine – found that to be good for the body, you should take a warm bath 1-2 hours before going to bed. This is the right time for the body to start cooling down naturally before bedtime. This factor helps you sleep easily. Frequency of bathing Chad Prather (Department of Dermatology, University of Louisiana) says the frequency of bathing depends on skin type and activity level. If you have dry skin or don’t have a lot of activity that leads to sweating, you can shower less often. However, consider whether you are in an environment exposed to a lot of dirt, bacteria or irritants. Mona Gohara encourages people to bathe once a day, at most twice a day. If your hair is prone to breakage, split ends, this could be a sign that you are washing your hair too often. This habit deprives you of natural moisture. Meanwhile, lazy to wash your hair can lead to greasy and cause the scalp to accumulate a lot of dandruff. You should give preference to products with not too strong detergents. Photo: Parler. Choose products that are good for your body Dermatologists recommend reaching for body washes or soaps that are described as “gentle cleansers”. Besides, sulfate-free shampoo should be preferred. One sign that the product you are using is not suitable is when the skin feels tight. In addition, do not use products with strong antibacterial and detergents. They tend to dry out the skin. Suppress the act of scrubbing Do not scrub vigorously or exfoliate too much. Mona Gohara considers products such as bath bags or mesh towels to be a reasonable choice. Besides, exfoliation should be done gently on the skin. You can bleach more than once a week. However, it is necessary to pay attention to the force of the hands when massaging. Exercises to strengthen men’s shoulders No equipment required, these exercises can be done anywhere and only take about 10 minutes a day.

The Vietnamese football team is present in the UAE to attend the 2022 World Cup qualifiers in the support of all fans. The past two matches have brought positive results, but many people cannot help but worry about the health of the players in the coming days. The reason is because the UAE is experiencing record hot days. The highest temperature recorded at the solar park in the town of Sweihan, 70 km northwest of Al Ain city in the emirate of Abu Dhabi, United Arab Emirates (UAE) was 51, 8 degrees Celsius on 7/6. Meanwhile, the temperature in Dubai and many other places such as Abu Dhabi, Sharjah, … was also recorded extremely high, up to 49 degrees Celsius. By June 8, the temperature had dropped to 46 degrees. This level of heat is considered extreme, which can be harmful to human health. People here are advised to wear umbrellas when outdoors and avoid direct sunlight. Many people living in the UAE say that this is the hottest summer they have ever experienced and they are asked to work and stay at home. Early summer temperatures in the UAE have risen sharply in recent weeks. The country typically experiences high humidity during the first few weeks of summer, with a long dry spell throughout July and August. It is forecasted that in the coming days, the United Arab Emirates (UAE) will continue to be hot and humid. The temperature in the hottest place, the town of Sweihan, has dropped, but still ranges from 43 – 46 degrees Celsius, extremely harsh. Besides the hot sun, Dubai and some other areas of the United Arab Emirates (UAE) also face fog due to high humidity, reaching 85-90%. For people in the UAE, hot weather has become the norm for them. Even in many countries around the world, the weather is more than 30 degrees Celsius, it is very hot, but the people of Dubai think that it is a good thing to signal that winter has arrived. In the summer in Dubai, people can’t even walk, swim, surf or eat outside due to the hot weather. These are only done in winter when the average temperature fluctuates between 15 – 30 degrees Celsius. Fortunately, in Dubai, there are air conditioners installed everywhere, so the life of the people as well as the national teams participating in the Wold Cup is also less difficult and harsh. However, because they are not used to the climate and often have to practice in the sun, fans are worried that the Vietnamese team may have health problems during the competition.

Protect your body by wearing sunscreen: Please wear a mask and cover with clothing (such as sun protection skirts, long-sleeved jackets, gloves, ankle socks…) of appropriate length and thickness when going out. especially between 10am and 4pm. In particular, you should choose fabrics that are breathable, easy to absorb sweat to ensure both protection of the skin from ultraviolet rays. Limit going out at peak times: The hottest time of the day is usually from 10am to 5pm, the hottest time is around 1pm to 4pm. Therefore, people should limit working and traveling outdoors during this period. Drink a lot of water before going out: Going outside, more or less also makes you sweat. Should drink a lot of water and properly to make up for the amount of water lost through excretion. This will prevent the body from getting dehydrated if you go out for a long time. Wear cool fabrics for sun protection: There are now better fabrics that offer full body sun protection. The most popular among them is linen, which has the advantage of being thinner than the old fabric, limiting the amount of sunlight absorbed into clothes and, importantly, being breathable to make the body more comfortable. Buy sunscreens with hats and masks. This will help prevent sunlight from entering the body. Avoid continuous operation between two environments with temperature difference: Doctors recommend that, on hot days, it takes a while to get out of the air-conditioned room from the outside (or vice versa, from the hot outside into the air-conditioned room) “Excessive” time should not be rushed from the house to the street. Because at that time, the body could not adapt to the large difference between indoor and outdoor temperatures, many people could not keep up with the body, leading to nosebleeds, headaches, fainting, and drunkenness. sunny… Shower before going out: You should cool your body as much as possible before going out, the reason is that when going out, the heat around the body will not increase too quickly. Add electrolyte-rich drinks: Drinking a glass of lemonade with 1 or 2 pinches of salt, 1 teaspoon of sugar, and some baking soda before stepping out in the hot summer sun can help prevent heatstroke. Buttermilk is another great at-home drink that helps cool the body. Avoid strenuous activities: Avoid strenuous activities when outdoors or working in the sun for long periods of time. Schedule outdoor work for a shady time like early morning or late afternoon. Use an antiperspirant spray: Going out in hot weather will make you sweat more. Therefore, before going out, you should use spray cosmetics to help prevent sweating effectively. In addition, the scent from these cosmetics also helps to mask the unpleasant sweat smell on the body.

Insulation film is one of the commonly found equipment on cars today, it is very useful on hot days What is car window film? Automotive insulation film is a type of film composed of many layers of different materials (also known as multi-layer coating) forming a filter plate of spectral ranges. Currently, there are 4 popular insulation film coating technologies, including: Nano Ceramic, Sputted Film, Metalized Coating Film, and Dyed Film. Insulation film gives the user and the vehicle a lot of different benefits The benefits of car window tinting Car window film has the main effect of insulating the outside environment, does not make the environment inside the car warm, stays cool and helps the car interior equipment not be damaged by the sun. heat, ensuring durability and quality when using. According to research, the heat in the sun will be radiated from 3 main sources: 57% from infrared rays, 5% from ultraviolet rays and 38% from visible light. Car window films can eliminate more than 80% – 90% of infrared and ultraviolet rays, but still have transparency, high light transmission, ensuring visibility while driving. The current car insulation films have the ability to insulate up to 50% – 65%. In addition, the film has an effective anti-glare function, while ensuring a clear and effective vision, making you safer and more comfortable. Insulation film helps reduce the temperature in the car, limiting the hot sun nắng The effect of sun protection, temperature reduction One of the most important effects that an insulating film brings to your car is the ability to resist hot sun, reduce temperature and high performance. This will help you always feel comfortable and cool when driving and sitting in the car even when it is hot outside. The film will also ensure no heat leakage, prevent heat from escaping to the outside, and maintain a stable temperature inside the vehicle. Your eyes and skin will also be maximally protected under the effects of the sun Maximum body protection Another equally important effect of insulating film is that it can provide maximum protection for the driver’s eyes and skin in the car. Insulation film has the ability to block most sources of UV rays (the cause of skin damage, potentially causing skin cancer) from 99% or more. This will give your skin maximum protection from darkening, aging and cancer, keeping you safe and comfortable when using a car. The interior of the car will also avoid maximum aging Protect car interior accessories Car window film is effective in protecting accessories and interior equipment in the car to the maximum, avoiding interior aging and fading caused by direct sunlight. damage during use. In the event of a sudden accident that breaks the glass, the shards will not be thrown to hurt the occupants of the vehicle Protect the occupants of the car when the glass is broken Insulation film does not work to prevent car glass from breaking. However, thanks to the insulating film, the glass will not be broken. Instead, the film holds the broken pieces of glass in place so they don’t splash and injure occupants. Sticking black insulation film also helps to ensure privacy inside the car Create privacy For those who want a sense of privacy when sitting inside the car, dark tinted film is the ideal solution. This type of film helps outsiders to not be able to see inside the car while occupants can still see outside.

The idea behind the study of nuclear fusion is to recreate how the Sun generates enormous amounts of energy, a process involving a large amount of heat and pressure that combine to form plasma, in which atomic particles fuse. with super speed. Scientists are looking to trigger and study these reactions on Earth with a variety of experimental equipment, but experts say that EAST, located at the Hefei Institute of Physical Sciences of the Academy of Sciences Chinese studies, is the most promising approach. Inside China’s “Artificial Sun”, the Tokamak Superconducting Reactor (EAST). Photo: Newatlas. The EAST is a metal toroidal device consisting of magnetic coils designed to sustain streams of superheated hydrogen plasma long enough for the above reactions to occur. In 2016, scientists at EAST heated a hydrogen plasma to about 50 million degrees Celsius and maintained it for 102 seconds. Then in 2018, they hit 100 million degrees Celsius, six times hotter than the Sun’s core, and lasted 10 seconds. According to the Xinhua , the latest test marks a big step forward, achieving a new record when heating the plasma to 120 million degrees Celsius and maintaining it for 101 seconds. In separate experiments, this “artificial sun” heated plasma to 160 million degrees Celsius in 20 seconds. The goal of EAST is to maintain the plasma at 100 million degrees Celsius for more than 1,000 seconds (about 17 minutes). These experiments are not designed to generate conventional electricity, but to advance the field of synthetic physics for next-generation devices such as ITER, the world’s largest nuclear fusion reactor is expected to be. completed by 2025. Similar to EAST, experiments on South Korea’s KSTAR reactor set a world record last year, maintaining plasma at more than 100 million degrees Celsius for 20 seconds. In addition, the country also announced the development of ITER and is expected to officially operate in 2035.

In hot weather, the body increases perspiration to stabilize body temperature and release energy. This process limits the accumulation of excess energy in the form of white fat – the culprit causing overweight and obesity. Increased temperature is also one of the factors that reduce cravings and loss of appetite, so the body does not have to load a lot of food, causing excess energy. Besides, the high temperature in summer makes the body always need to be supplied with more water. Drinking plenty of water also helps to increase excretion through sweat and aids in weight loss. Taking the stairs is the best way to lose weight. People who work out to lose weight will find summer to be the ideal time to do so. Because exercise in the summer will help lose weight effectively, when this process burns a lot of excess fat, converts it into water and escapes through sweat. Even during the days when you have to limit going out to fight the epidemic, you can immediately use your daily activities. To lose weight, it is necessary to take advantage of small exercises whenever possible such as: doing housework, walking quickly, climbing stairs or doing sit-ups when doing laundry, cleaning the house, cleaning out the closet, walking at place… When you want to lose weight, find errands, walk to heat up your body. If you only move from floors 1-3, instead of taking the elevator, you should take the stairs. Take advantage of all means to be able to walk, taking a regular walk, sometimes just 15 minutes a day, is very good for burning energy and losing weight effectively. Although summer is a good time to start losing weight, however Health of life Note that you make your weight loss journey effective, without leaving complications or becoming a corpse. The exercise even indoors, with daily activities also needs to be conducted scientifically, because if performing intense exercises in a closed and hot room, it will easily cause dehydration, cardiovascular effects, even danger to life. Therefore, you should choose exercises that are suitable for your health, provide enough water before/during/and after exercise. Summer creates conditions to shorten the weight loss route, but that does not mean that weight loss is arbitrary. Women should apply a scientific way to lose weight, which has been advised by a doctor. Do not combine weight loss solutions with the use of laxatives, hot wraps, fat-burning creams, weight loss teas… Because these ways do not affect the culprit causing weight gain is white fat, but only cause dehydration, electrolyte disturbances that make the body vulnerable.

Two of China’s top track and field athletes were among 21 people who died due to extreme weather during a 100km race in Gansu province on May 22. Those are two names that are no longer strange in the world of athletics: Luong Tinh, a super-marathon champion, and Hoang Quan Quan, a deaf long-distance runner. “We have lost the masters of this sport. This is an earthquake for our sport,” wrote one Weibo user. Luong Tinh in an earlier race in Hong Kong. Photo: Sportograf. Athletes had a hard time when the race was interrupted by temperatures dropping to freezing. Survivors said the weather forecast said there would be wind and rain, but did not mention anything as extreme as what they experienced. The mountain race had to be stopped when some of the 172 runners went missing, and a major rescue operation was launched. The regional government was heavily criticized for not having a contingency plan. China’s Central Commission for Discipline Inspection (CCDI) said that some local officials had put profit above safety, which led to the tragedy that left 21 people dead. Great loss Luong Tinh is one of China’s most successful ultra-marathon runners and is fondly called “Saint Liang” or “General Liang” because of his ability. The 31-year-old has won many long-distance races in the country, including the Ultra Gobi in 2018 – a 400 km race through the Gobi desert. According to pictures taken near the start of the race on May 22, which were widely circulated on Chinese media, he was only wearing shorts, a light jacket and a cap. By the time he was found by rescuers, he was already showing no signs of life. According to pictures taken near the start of the race on May 22, which were widely circulated on Chinese media, Luong Tinh was only wearing shorts, a thin jacket and a cap when running. Photo: Weibo. On Chinese social media, fans mourned his death, describing it as a “huge loss” for the country. “Without General Salary leading the way, who will the other super marathoners look to?”, one commented. Another victim, Hoang Quan Quan, 34, is known for winning the deaf men’s marathon at China’s 2019 National Paralympic Games. According to local media, he is a native of Sichuan, became deaf at the age of one after a “drug accident”, and also cannot speak. He did not excel in his studies and struggled to get a steady job. He often had financial difficulties and had to eat instant noodles for a meal. But what he does best is run, so he competed in races for years in hopes of winning the prize money. The May 22 race rewards runners 1,600 yuan ($248) each if they complete the run. Local media reported that after learning of his death, a friend of Hoang Quan Quan cried thinking about what he may have suffered in his final moments of life. “He’s deaf and can’t speak, he can’t even call for help,” said the unnamed friend. What happened at the race? On social networks are appearing more and more sharing about this race. The race starts at 9am on May 22. One survivor said the weather forecast caught them off guard. He felt that the weather was not normal that day, but the participants were not wearing warm enough clothes, many of them wearing short clothes. “I ran 2 km before starting to warm up… but the problem is that after running this 2 km, my body still hasn’t heated up,” the contestant said on her WeChat account. About three hours after the race started, the mountain track area of ​​the race experienced hail, heavy rain and high winds, causing temperatures to plummet, according to officials in the nearby city of Baiyin. A runner named Mao Shuzhi told Reuters : “The rain was getting heavier and heavier, at that time I had run about 24 km and had not reached the mountain.” She decided to go back to the hotel, and had been struggling with severe hypothermia on the way back. “At first, I regretted it, thinking it might just be a shower, but when I saw the gusts of wind and the big storm through my hotel room window when I returned, I felt so lucky because decided to come back.” Many athletes were stranded, cold and lost their way due to the weather affecting visibility. Rescue crews at the scene. Photo: AFP. An unnamed runner quoted by The Cover described the freezing rain as “bullets in the face”. He said there was a particularly steep section of the mountain and the open ground had nowhere to hide. “The rain really hurt, and the wind was so strong that you had to close your eyes,” he said. He added that even if someone brought a thermal blanket, it would be ripped apart by strong winds. Some of the runners who ran further fell off the trail into deep ravines. It is unclear how many of them survived. State media said a rescue operation involving more than 1,200 people with the help of thermal imaging drones and radar detectors had been launched. But rescue efforts have come too late for many victims. The incident has sparked public outrage on Chinese social media, mainly aimed at the Baiyin government and condemning the organizers’ lack of contingency plans. At a press conference on May 23, Mayor of Baiyin, Zhang Xuchen – who also fired the starting shot of the race – said: “As the organizers of the event, we feel guilty and We express our deepest condolences and sympathies to the families of the victims and those injured.”

The group consists of eight first-year students: Chu Minh Nhan, Cao Khanh Gia Hy, Nguyen The Binh, Ho Huynh Gia Bao, Tran Duy Khang, Nguyen Duy, Ngo Ha Gia Bao and Mai Hoang Kim Son. The group made the fabrication under the guidance of three lecturers, Prof. Dr. Quan Thanh Tho (Deputy Dean of Faculty of Computer Science and Engineering), Dr. Le Thanh Long (lecturer of Faculty of Mechanical Engineering) and Dr. Vo Thanh Hang (Deputy Head of Faculty of Computer Science and Engineering). lecturer in the Department of Environment and Natural Resources). A group of students worked hard together to make a thermometer Dr. Vo Thanh Hang (female), Assoc. Prof. Dr. Quan Thanh Tho (shirt) and a group of students next to an automatic body temperature measuring device. Photo: NTCC Chu Minh Nhan, a member of the group, said that the group is currently completing a number of features such as the data entry table, the frame structure… according to the suggestions of the teachers and teachers. It is expected that in the middle or the end of June 2021, the group will complete the apparatus and put it into use at the school’s entrances. Compared with other machines on the market, the advantage of IoT-integrated automatic body temperature and hand washing machine is that it is programmed with IoT to recognize faces (check student IDs and faces) to remind you to wear a mask. voice. The device will automatically measure the body temperature and warn when the body temperature exceeds the normal range. Update data on user information and temperature of use, record information, when the user is using the machine… The machine also supports automatic hand washing with a sufficient amount of antiseptic solution. In particular, the data (temperature measurement results, entrance time, facial recognition images) will be stored and transmitted to the central server. Medical staff will easily access and retrieve data for control and tracing of suspected COVID-19 cases. Dr. Thanh Hang, instructor, said that the thermometer is a product developed by a community project and entered the top 10 of the soft skills class of the school’s international training program. After that, students continued to research and develop machine manufacturing, combined with smart internet usage features, to improve usage efficiency. According to Dr. Thanh Hang, the group has now registered a student scientific research project (start-up program) and manufactured according to the university’s order to use in the prevention of COVID-19 at the University of Science and Technology.

On May 21, G7 pledged to completely stop funding coal-fired power plants. On May 21, environment ministers from the Group of Top Industrialized Countries (G7) agreed to take concrete steps by the end of the year to stop government funding for coal-fired power plants as part of efforts to curb global warming. In a statement after the two-day video conference, the G7 environment ministers said: “(We) are committed to taking concrete steps towards an absolute end to the new direct government assistance. for international coal-fired power generation by the end of 2021, including through Official Development Assistance (ODA), export finance, investment, financial support and trade promotion” . However, the statement did not mention the possibility of phasing out coal-fired power generation, leading analysts to believe that the G7’s call would have little impact on global efforts to tackle the problem. climate change issue. The removal of government support for fossil fuel financing, which emits large amounts of greenhouse gases that warm the Earth, is seen as essential to limiting the growth of fossil fuels. global temperature increase at 1.5 degrees Celsius, above pre-industrial levels.

David Garcia bakes pizza on lava from the Pacaya volcano in San Vicente Pacaya, Guatemala on May 11, 2021. (Photo: AFP/VNA) Guatemala’s Picaya volcano began erupting again in February with a lava flow more than 1km long. Active volcanoes scare a lot of people, but for local resident David Garcia, this is where he came up with a unique idea – baking pizza using the heat from lava flows. That is the reason for the birth of a pizza called “Pizza .”. Picaya .” Follow Mr. Garcia, a 34-year-old auditor, to witness pizza baking at the foot of Picaya volcano and visit volcano This is a very enjoyable experience. Ingredients Pizza Picaya is like any other ordinary pizza, the main difference is that the special oven is created from lava and the mold can withstand temperatures up to 1,000 degrees Celsius. After spreading the dough into a special mold and adding the necessary ingredients such as meat, sausages, cheese, vegetables, tubers…. cake. With high heat in special “ovens”, Picaya pizza is ready to serve guests in less than 15 minutes. Visitors enjoying this cake all feel the strange taste of pizza baked on Picaya volcanic lava. Of course, in order to bake the cake, Mr. Garcia must wear protective gear. Mr. Garcia promoted this experiential tourism model in 2014 after he discovered several locations at the base of Picaya volcano that had the ideal temperature for baking pizza. Initially, there were not many customers, but gradually his Pizza shop attracted the curiosity of many people and now everyone who comes to Guatemla knows about Picaya pizza. Even as the Picaya volcano “wake up” and spewed lava over the past several weeks, Mr. Garcia baked cakes directly on the red lava. Pacaya, located 2,552 meters above sea level, is one of three active volcanoes out of a total of 32 volcanoes in Guatemala. In addition to this volcano, two other active volcanoes in the country are Fuego in the central region and Santiaguito in the west. Pacaya volcano has erupted since late February, affecting the lives of about 38,000 people in 20 surrounding areas.

Theoretically, the limit of low temperature in the universe is called “absolute zero”, the value is 0 K, converted to the commonly used temperature unit of -273.15 degrees Celsius. And to prove the existence of absolute zero, mankind has had to conduct a lot of experiments over a very long time and the story of this limit value is also quite interesting from a scientific perspective. because when the concept was introduced, no one could conduct experiments near that temperature. But the specific concept of absolute zero was not formed overnight, instead it was studied, observed and concluded by generations of scientists. As early as 1702, the French physicist Guillaume Amonton questioned whether there was a limit to cold. He improved a thermometer that used air and mercury. The volume of air changes with temperature, causing some of the mercury to move to show the scale. The minimum value of the thermometer has a limit, which is the point 0 (according to today’s calculations, it is about -240 degrees Celsius). Until the end of the 18th century, many physicists tried to discover this low temperature limit. In 1785, Jacques Charles, a French physicist discovered the relationship between the temperature and the volume of a gas at constant pressure. In his experiments, he found that in the case of constant volume, for every 1 degree Celsius decrease, the pressure of the gas will decrease by 1/273 of its pressure at 0 degrees Celsius. According to this rule, when the gas temperature drops to -273 degrees Celsius, the pressure becomes zero – vacuum environment. Later, the English physicist William Thomson (ie 1st Baron Kelvin) gave the first formal form based on the summation and speculation of his predecessors about the concept of absolute zero – understood as a state in which the interior of the object can be reduced to zero and completely stop the motion of the molecules. Accordingly, one of the ultimate goals in the field of thermodynamics is a great battle to challenge absolute zero. And of course, this goal cannot be achieved overnight. Michael Faraday. The first major figure in this race was Michael Faraday. By 1845, he had obtained various forms of liquid gases through primary compression. With his technology at the time, he was able to achieve temperatures as low as -130 degrees Celsius. However, during that time he was still unable to liquefy some gases such as oxygen, nitrogen and hydrogen. This was due to theoretical limitations at the time, so Faraday believed that these gases were “permanent gases” and could not be compressed into a liquid state. In the late 1870s, French physicist Louis Paul Cailletet pioneered the production of liquid oxygen and liquid nitrogen, which could be obtained at low temperatures of -183 degrees Celsius and -196 degrees Celsius, respectively. To achieve this, Louis Paul Cailletet applied the Joule-Thomson effect. James Dewar. The next important person was a Scottish chemist and physicist – James Dewar, who would challenge hydrogen, the last “eternal gas” at the time. Scientists at the time expected to be able to produce liquid hydrogen at as little as -250 degrees Celsius. This temperature was an impossible challenge with the technology and equipment at the time, so Dewar had to invented new devices to be able to conduct this research. His plan was to use a gas that could be compressed and liquefied at room temperature, then allowed it to expand and return to a low temperature and then continue to use this temperature to liquefy other gases that are more difficult to liquefy . In this way, after a series of stages, it is possible to reach a temperature low enough to liquefy the hydrogen. But to do that, Dewar was forced to create new equipment and tools for research, which required a lot of money. So Dewar demonstrated some of the unique properties of liquefied petroleum gas to guests in the Royal Society’s laboratory, and used experiments to attract investors’ attention. But the experiment didn’t go well, in 1886, a terrible explosion occurred in a London laboratory, Dewar accidentally mixed liquid oxygen with liquid ethylene and caused an explosion, which subsequently caused the His scientific career was almost over. Soon, however, Dewar produced 20 cubic centimeters of liquid hydrogen through a multistage cascade of methyl chloride-ethylene-oxygen-hydrogen. At that time, the tank had a pressure of 180 atm (atmosphere) and the temperature reached -205 degrees Celsius. Dewar then put liquid hydrogen into the expansion tube and watched the temperature of the thermometer gradually decrease, eventually, he achieved a new record of -252 degrees Celsius, considered to have completed the impossible challenge for the predecessors. Faraday duty. However, shortly after the experiment was successful, a new gas was born – the inert helium gas. Next, Dutch physicist Heike Kamerlingh Onnes went on to undertake this research and built a factory to produce magnetic liquid hydrogen using Dewar’s equipment and miraculously produced liquid helium, reaching temperatures lows of -269°C (4.2 K). At this near absolute zero temperature, many substances will exhibit unprecedented states, including fluid mechanics, electromagnetism and other related properties, which also earned Onnes the Nobel Prize in Physics in in 1913. But so far, no one has been able to conduct an experiment to achieve theoretical absolute zero – the value is 0 K, converted to the commonly used temperature unit of -273. ,15 degrees C.

Having to go out on the hottest days is a nightmare. But because of work, many people are forced to move in outdoor temperatures up to more than 40 degrees Celsius. In two big cities like Hanoi or Ho Chi Minh City, in addition to the green trees that can create shade, when the elevated railway appears, it creates a “paradise” between hot weather next to the “terrestrial” road. prison”. It is also thanks to the elevated railway project that many people in traffic can enjoy the cool part of the road. In particular, when stopping at a red light, you do not have to suffer from the scorching heat of the summer heat. After officially entering the summer, the shady part is created from the elevated railway works, people take advantage of it to enjoy. If you go out in the summer, surely the “heaven” part of the road has a higher traffic density than “hell”. In some roads, the “heaven” part of the road is usually reserved for cars, but because they want to avoid the sun, many motorcyclists go in. Image of stopping at a red light at an intersection in Hanoi in the middle of a hot summer. A clear line separating “heaven” and “hell”. Standing in the shade waiting to pass the intersection is no longer a strange thing. The roads without the shade from the elevated railway, the “heaven” is created from the old trees in Hanoi. Experiencing but burning moments with the hot road surface, stopping at red lights in shady places is what many people choose. Many motorbikes, when stopping at red lights, have chosen to stand under the shade of a tree, tens of meters from the prescribed line to wait for the red light. In the afternoon and early afternoon, when the outdoor temperature sometimes reaches over 40 degrees Celsius, these images are not too difficult to find at traffic junctions in the city.

According to a scientific study, 30% of unwanted heat in the house comes from glass doors. Therefore, the simplest measure to keep the house cool is to always pull the curtains and also choose dark colored curtains to avoid heat radiation from entering the room. If you don’t want to turn on the air conditioner a lot, you can use a simple trick with ice and a fan. Place ice in a bowl and place in front of a fan. The rising cold air will then be blown around the room by the fan to help reduce the heat very well. In the summer, but you still want to lie down, you should choose spring mattresses to help more ventilation. Changing your sheets regularly will also help keep you comfortable in the heat. Dirt and dirt stick for a long time, making it difficult for the air to circulate and stick to people. If you want to feel more comfortable, first lower your body temperature by wearing light, comfortable clothes, drinking cool drinks and using cold towels to cool your skin. Turn on exhaust fans in kitchens and bathrooms to help eliminate hot air from cooking or after you’ve finished showering. Putting plants in the house or planting vines as a fence will help reduce the indoor temperature significantly on hot days. Trees also work to prevent dust and filter the air, making you feel comfortable. Replace incandescent bulbs with compact fluorescent lamps. Incandescent lamps give off a huge amount of heat, the warm yellow color makes the room more stuffy. Window film is also a good idea and useful when you want your house to be cooler on a sunny day. Another trick to lower the room temperature is to put a basin of water in the room. On the high temperature background, the water evaporates, reducing the temperature significantly, helping the bedroom to be cooler. Installing 2 windows in the same room can facilitate natural air circulation, release hot air and take advantage of natural light. If your home is located in a location with a lot of harsh sunlight, choose cool colors such as turquoise, cream, white and blue, etc. to paint the walls of the house. These colors have the effect of reducing heat absorption, relieving fatigue, and relaxing the mind. Please watch the video: Another great Japanese invention. Source: Yan News

At around 11:30 a.m. on May 11, a lot of freelance workers, loading and unloading at Dong Xuan and Long Bien markets, are still working hard. They covered the towel, took advantage of the cold water and put it on their heads to fight the rising heat. Information from the National Center for Meteorological and Hydrological Forecasting people should limit going outdoors at noon because the heat can cause dehydration, exhaustion, and heat stroke due to heat stroke. people when exposed to high temperatures. Ultraviolet radiation at the index is very dangerous, people should cover up when going out, apply sunscreen, wear sunglasses and a hat is required. 12 noon on May 11, the outdoor temperature is up to 44 degrees C Freelance workers in Hanoi reel from the scorching summer heat Many labors cover their bodies to protect themselves from the sun Hanoi streets are like a fire pan. The hot weather in Hanoi makes the air become hot and uncomfortable, and people find ways to shield them when they go out on the street. Towards noon, the outdoor temperature increases, although the temperature has not reached its peak, but it also makes people shielding when traveling on the road. Streets seem to evaporate due to the heat effect Workers rest under tree canopy to avoid the scorching heat on Tran Duy Hung street

Mars probe ship. Generates oxygen on other planets The Perseverance expedition ship of the US Aeronautics and Space Administration (NASA) has just made history. It successfully experimented with converting carbon dioxide gas from the Martian atmosphere into oxygen. This is the first time that oxygen production has been performed on another planet. The Mars experiment using local oxygen resources, called MOXIE, is a device the size of an automobile battery and is placed inside the Perseverance. Massachusetts Institute of Technology (MIT) is the manufacturing unit. MOXIE is made of a heat-resistant material such as a nickel alloy. It is designed to withstand extreme temperatures of up to 800 degrees Celsius. The device is coated with a thin layer of gold to prevent heat and damage to the Perseverance vessel. On the first test run, MOXIE generated 5.4 grams of oxygen – enough for an astronaut to breathe easily for 10 minutes while still performing normal activities. Engineers will conduct additional tests and find ways to increase oxygen production. By design, MOXIE can generate 10 grams of oxygen per hour. NASA expects the development of experimental instruments not only to help generate oxygen for astronauts in the future, but also to help generate large amounts of oxygen to be used as a rocket launcher for the return journey without. must be transported from Earth. The Perseverance expedition landed on Mars on February 18 to perform a mission to search for signs of microbial life on the “Red Planet”. In the coming years, the Perseverance ship aims to collect 30 soil and rock samples to send back to Earth (estimated around 2030) for analysis. Dang Vu Tuan Son, Club of Astronomy and Astronomy of Vietnam, said that oxygen-rich atmosphere should not be seen as steel evidence for life on other planets. Nowadays, to look for signs of life, scientists often use biological structures as guides. Its biological form and life-forming compounds serve as indirect evidence for its presence. On Earth, the oxygen in our atmosphere is one of the most obvious biological characteristics that an alien astronomer can notice. It is only in our atmosphere in such large quantities because plants and bacteria photosynthesize it has been creating it for billions of years. Oxygen is not synonymous with life A new study published April 13 in the journal AGU Advances suggests that terrestrial planets around stars like the Sun can develop oxygen atmospheres without help. from life. This means that detecting oxygen on a planet does not mean that the planet is capable of life. This study uses a computer model that allows scientists to experiment and observe the evolution of a planet. In the first model test, the researchers attempted to accurately reconstruct our Earth. Then they changed the initial conditions to different from what was made up of Earth, and the results they got showed that there are many cases where the planets still contain oxygen but do not require any changes. living. In fact, they have found three main ways for a rocky planet to have an oxygen-rich atmosphere without the presence of life. The first scenario is an Earth-like liquid water planet with oceans 50 times (or more) larger than on Earth. All of that water puts great pressure on the planet’s crust, shutting down the geological activity. This prevents things like the weather and the melting of rocks being two factors that cause oxygen to disappear from the atmosphere. The second scenario is the opposite: A dry desert world with 30% less water than Earth and they will solidify with a “steam atmosphere” for about a million years. This provides a large amount of oxygen in the atmosphere, as sunlight breaks down the molecules of water and hydrogen released into space. And because the planet’s solid desert surface cannot remove any oxygen, it stays in the atmosphere. The last way for a lifeless planet to have an oxygen-rich atmosphere is if the original planet had a higher ratio of carbon dioxide to water than the early Earth. In this case, the planet undergoes a greenhouse similar to what happened on Venus and becomes too hot for oceans to form in the first place. It is also too hot for volatiles to exist in the planet’s mantle, where they will isolate oxygen through chemical reactions. Instead, these volatiles are in the atmosphere, where they can no longer remove oxygen. The planets could have better life than the Earth Researchers have identified more than 20 planets outside the Solar System that have better conditions for life than Earth. Some of these planets have orbits stars that are probably even better than the Sun. A study led by Dirk Schulze-Makuch at Washington State University published in the journal Astrobiology details the features of planets with superlative potential, including is composed of planets that are older, slightly larger and warmer, and possibly more water than Earth. Life can also easily develop on planets moving around slower-changing stars that have longer lifespans than the Sun. The top 24 candidates for habitable planets are all located more than 100 light-years away from us, but Schulze-Makuch says this rescue could help future observations to focus properly, such as the James Webb space telescope, NASA’s LUVOIR space observatory and ESA’s PLATO space telescope. Researchers have selected planetary systems that are likely to have terrestrial planets moving around the parent star in the region of the habitable zone (an area that allows water to exist as a liquid on the planet’s surface) from Kepler’s archival data on transiting exoplanets. Our sun has a relatively short lifespan, less than 10 billion years, because it takes nearly 4 billion years for complex life to form on Earth, so many stars are similar to the Sun (types of G stars). ) may run out of fuel before life can develop. Along with monitoring the types of G stars, the researchers are also observing K-stellar systems, which are colder, smaller, and fainter than the Sun. Type K stars have lifespans that can last from 20 to 70 billion years. That allows the planets moving around it to grow older and allow life to have more time to have life as complex as Earth does today. However, for the planets to stay alive, the planets could not be too much as they could end geothermal activity and no longer have a protective magnetic field. Earth is about 4.5 billion years old today, but researchers think that the most ideal time for life on a planet is between the ages of 5 billion and 8 billion.

Photo of the Ingenuity Mars helicopter taken by NASA’s Preseverance spacecraft. Photo: NASA. Open a new door Ingenuity attached to the belly of the Perseverance probe landed together inside Mars’ 45 km wide Jezero crater on February 18. On April 3, a solar-powered helicopter was dropped from Perseverance’s belly. NASA is expected to make history on the Red Planet with its first self-powered flight powered by energy. “That is extremely important. Technological inventions will open a door to completely different tools. And for me, that’s very interesting. We still haven’t envisioned all the benefits of this new technology, ”said Thomas Zurbuchen, NASA’s Deputy Administrator. Ingenuity is considered a “technology show”. Because, the expected flight of this helicopter on Mars is designed simply to demonstrate the efficiency of the technology. Although there is an onboard camera to take pictures during the mission, it’s the only feature on the plane that is not directly related to Ingenuity’s take-off. “The speed of light is too slow for us to actually control it in real time,” said Mr. Zurbuchen. In addition, the team must find a way for the helicopter to fly over Mars in a challenging environment, with a very thin atmosphere. Obviously, flying on another planet is not easy for helicopters. This is an exciting moment in the history of spacecraft and technology. Many people questioned whether Ingenuity was equipped with any technology application to achieve such a feat. Scientists hope to use Ingenuity to explore in the future, according to Zurbuchen. Because, a small helicopter can “probe many places that we can not go to by plane”. The expert also explains that Mars has some interesting things. The crater walls and other destinations will be interesting to study up close, while astronauts won’t be able to explore. In the future, helicopters could be an important asset for both robot and human exploration on the Red Planet, Mr. Zurbuchen said. However, as mentioned before, Mr. Zurbuchen said, there are many applications to this technology that are yet to be developed. Science breakthrough The deployment of the Ingenuity helicopter flight plan on Mars aims to demonstrate that humans can fly in the extremely low density, reduced gravity and extreme temperatures of the red planet. In addition, the amount of sunlight the planet receives is only half that of Earth; At night temperatures down to -90 degrees C cause electronic components to crack and freeze if left unprotected. While a mission on Mars is not an easy task, NASA is confident that this small helicopter can overcome the challenge. However, the first flight will be at low altitude and take place shortly. Members of the mission group said, Ingenuity (weighing 1.8 kg) is expected to fly no more than 3 meters above the floor of the Jezero crater on Mars. The helicopter will stay high for 40 seconds or so. However, even such a modest flight time would be an achievement. Because, Mars’ atmosphere is only 1% thicker of Earth. Aircraft generate lift by pushing air. However, according to Project Director Ingenuity – MiMi Aung, of the NASA Jet Propulsion Laboratory (JPL) in Southern California, on Mars, there are fewer molecules to propel. That disadvantage outweighs the benefit that helicopters get from Mars’ weaker gravity. So Ingenuity has to behave a little differently from its predecessors on Earth. Specifically, Ingenuity propellers are made of carbon fiber, made for Mars. They are particularly large compared to the overall 48 cm high helicopter. Each wing extends 1.2 m. Those propellers will spin at about 2,500 rpm to bring Ingenuity off the ground. This is much faster than that required by a 4lb motor. Besides, Mars is also a place where the cold is “piercing”. Perseverance measured the Red Planet’s nighttime temperature to minus 117.4 degrees F (minus 83 degrees C) on the surface of Jezero. So Ingenuity has a fireplace so it won’t freeze. Currently, it takes more than 15 minutes for an order to be sent from the control agency on Earth to Mars. Real-time operation with the joystick is therefore not an option. Flight orders must be sent in advance. However, that doesn’t mean Ingenuity is going to be in trouble. This helicopter will be able to do many tasks on its own. For example, Ingenuity can analyze photos captured by the downward-facing camera. From there, locate it. The images will be in black and white. Ingenuity is also capable of 13-megapixel color photography. There are a series of complicated devices that are inserted into the “small body” of Ingenuity, although the helicopter does not carry any scientific tools. Cameras, electrical systems, avionics systems, and communications equipment for data transfer to Perseverance were all introduced into Ingenuity. In fact, the size of devices like objects has made it impossible for many helicopter missions on Mars. Ms. Aung and her colleagues tested Ingenity extensively on Earth before launching. Ingenuity used to have to fly in a special chamber at the JPL – which simulates the conditions of the Red Planet. Thanks to that, Ingenuity has been doing well on the Jezero crater since its separation from Perseverance. Therefore, the scientists expressed confidence in Ingenuity’s mission. If successful, Ingenuity will fly again – up to 5 times in about a month. Ingenuity helicopters pave the way for future space exploration.

The Northeastern provinces today also started to have local heat with the highest temperature of over 35 degrees Celsius. In Hanoi, the highest temperature of the day is up to 33 degrees Celsius, it is cloudy but the air is still hot. , the temperature increases rapidly in about 12-16 hours. The heat wave in the North is likely to last until April 25. Immediately after that, the area received 2 consecutive cold air waves. On April 26-28, the weather in Hanoi and the Northern provinces turned cold with large-scale thunderstorms. Photo: Duy Hieu. Specifically, the meteorological agency said early next week, a wave of cold air appears compressing the low pressure trench will cause showers and thunderstorms on a large scale in the North and North Central provinces. On April 26-28, the weather turned cool, but accompanied by extreme thunderstorms. On April 29-30, another cold air appeared, combined with high wind convergence, continued to cause moderate rain, heavy rain for the two areas above. Experts warn that on small rivers and streams in the northern mountainous region, a flood is likely to occur with flood amplitude up to 1-3 m. Flash floods and landslides are likely to occur in the mountainous provinces of the Northwest and North Vietnam. Thus, on the occasion of the holidays April 30 to May 1, the weather in the North is likely to turn badly. It is cold, some places turn cold, accompanied by thunderstorms. According to the forecast page Accuweather , in Hanoi, the lowest recorded temperature in the coming cold wave is 25 degrees Celsius. It will be chilly, with showers and thunderstorms continuously on April 26-28. After that, the rain fell. In Ho Chi Minh City and the Southern provinces, local thunderstorms still appear, focusing on the afternoon and evening. In the last 10 days of April, the Central Highlands and the South had many days of showers and thunderstorms. People need to be on the lookout for cyclones, lightning, hail and strong winds. Meanwhile, the water level upstream of the Mekong River continues to rise with the tide. The meteorological agency said saline intrusion in the Mekong Delta increased gradually and is likely to reach its highest level in the last days of April. On April 23, many places in the Northwest recorded a popular temperature of 35-38 degrees Celsius. The hot sun extended to most of this area and spread down the central provinces. The highest temperature observed during the day is 40 degrees Celsius in Muong La (Son La).

Especially on the occasion of the new year, the orchid is very suitable as the messenger conveying the message of love, meaningful wishes showing the thoughtfulness and heart of the giver. Not only that, Tet’s orchid is also a symbol of longevity, because the longevity of the flower pot lasts quite a long time. With attractive colors, strong shape, large and thick petals, moth orchids will bring good things in the new year, wish for a perfect happiness, everything is as expected. In order to make a beautiful and meaningful standard orchid pot, especially on the occasion of Tet, the stages of taking care, preserving and using water … are quite sophisticated and very cautious. Talking with some employees at the garden houses, the owner of the orchid business at some points for Tet, the staff here shared that the Ho scallop is a flower symbolizing wealth and luck. Luckily and prosperous, quite picky care, especially with regard to the environment, temperature and weather. As for the market, as well as the choice of customers in this year’s Tet market, through exchange, Mr. Do Van Duc, owner of a large orchid business in Ha Dong District, Hanoi City) said, “The market for Tet this year, the demand for playing orchids is very high. In this year alone, our facility nearly doubled production (about 80,000 trees) to serve the Tet market, mainly focusing on colors such as yellow, red, purple, pink … but currently there is no stock for sale. , even though some customers booked for a few days of Tet “. … because the orchid market has only a few hundred thousand dong flower pots, but there are also large flower pots with tens or even hundreds of millions dong. According to Doan Trang, the owner of the orchid business in Dong Da district, Hanoi, this year, due to the influence of COVID-19, the import of orchids (mainly from the Taiwan market (China). There are many difficulties, so flower products are consumed faster than every year .Potted moth orchids of all types, colors and sizes are sold for an average price of moth orchid, priced from 250,000. – 300,000 VND / branch For VIP customers, there are flower pots up to several tens of millions VND. “Therefore, to take care of customers most carefully, when Tet comes, I myself and the special staff pay special attention. Respect the types of pots, flowers, decorative accessories so that there is a harmonious and beautiful combination, bringing the luxury to the house and the blessings of the homeowner with the desire to continue to retain customers “. According to Uncle Dinh Duc Thien (customers who buy orchids from Ninh Binh), because he has a passion for Ho scallop orchids, when Tet comes, the spring comes, Uncle Thien always tries to find himself a pot of Ho moth orchids. Most picky even though it has to go far to choose. For many people, when life is more prosperous than ornamental plants and ornamental flowers such as kumquat, which are indispensable every Tet to spring, in recent years, many people choose to celebrate Tet. . In 2020, although the economic conditions are affected by the COVID-19 epidemic, Mr. Thien continues to enjoy his passion. “This New Year, I see many people like yellow and white orchids, although it is more expensive. Perhaps this color means wealth, luck, satisfaction, fortune, and prosperity ”- Mr. Thien added. According to experts on orchids, depending on space, age, destiny … each person should choose for themselves large or small orchid pots, and corresponding colors. If you want a cozy Tet holiday, you should choose small beautiful white flower pots to make the house more luxurious and sophisticated, or if you want to decorate a spacious space, a colorful flower pot with Exquisite meticulous design will be the right choice. Phalaenopsis orchids in addition to their beautiful, durable and luxurious colors, but also have a meaning of peace and prosperity for the new year. Therefore, although this flower is expensive, it is still favored by consumers as gifts for relatives during Tet. However, in order to have a brilliant and unique orchid color, the player should pay attention to some notes such as: it is necessary to place the orchid pots in the bright areas of the room; should not arbitrarily change the structure of the tree; should not water too much, or watering is not hygienic… /.

It is forecasted that, due to the influence of the southeastern edge of the western hot low pressure region combined with the cyclone effect, today (April 24) and April 25, there are hot sun with the popular highest temperature of 35-38 degrees C, in some places, the hot sun with the highest temperature of over 39 degrees Celsius; In the northeastern provinces, there is local heat with the highest temperature over 35 degrees Celsius. Illustration The daily lowest relative humidity is 45-60%. The time has a temperature of over 35 degrees from 12-17 hours. Due to the effects of intense heat and heat combined with low humidity in the air and southwest wind causing strong blows, there is a high risk of fire, explosion and fire in the residential area due to demand. Demand for electricity increases and high risk of forest fire in the central provinces. In addition, hot weather can also cause dehydration, exhaustion, and heat stroke due to prolonged exposure to high temperatures.

In fact, dry skin can also occur in summer, especially in less humid climates or when the air conditioning is too low. British GQ has come up with ways to help beard “fight” dry skin. Take a cool bath A long, hot shower affects your skin. It removes moisture and natural oils with the effect of making the skin soft, smooth. Additionally, hot water can dry out as well as irritate the skin. Therefore, men should bathe with cool water. The top reason why experts recommend a cool bath is that it increases blood circulation. Men should also maintain a bath frequency once a day. According to the Healthline People with high blood pressure or cardiovascular disease when exposed to low temperatures will activate the circulatory system to reduce inflammation and help prevent heart disease. Cold water makes skin brighter, firmer and younger looking. Photo: @jackie_ish. Moisturizing the body British GQ Think the best time to hydrate your skin is when you have finished bathing. At that time, the body no longer has dirt, toxins or other barriers. As a result, skin will be fully absorbed by the benefits of the care product and with less breakouts. This is especially good when you apply it in the evening. You can keep your skin moisturized and enjoy the benefits of your care. At the same time, the body enters the regeneration and recovery cycle with a lightweight, fast-drying cream. You should prioritize skin care products with super moisturizing ingredients. Photo: The Manual. Use balm Balm (lotion) and cream (cream) tend to nourish and protect the skin’s moisture barrier better than lotions (lotions) due to their high oil content. Prioritize products with super moisturizing ingredients such as jojoba oils / extracts (anti-inflammatory, containing vitamins B and E), hyaluronic acid (increasing moisture, reducing the appearance of wrinkles) and shea butter ( anti-inflammatory, nourishing, firming and soothing). In addition, men may consider some mild exfoliating recipes including lactic acid or glycolic acid (cleanse, fade and freckles …). Skin cleaning products can sometimes dry out the skin. Photo: Best Life. Use moisturizing soaps and cleansers One of the “culprits” that cause dry skin are skin cleansing products. Their job is to remove dirt and excess oil. Sometimes, they “do too well” to do their job. Therefore, men need to stock up on products that promise to hydrate or retain moisture while they cleanse the skin. In particular, you need more moisture when winter comes. Use a humidifier Your nighttime regimen should focus more on skin products. Men, on the other hand, should apply lotion oil before bedtime to help skin cells regenerate overnight and fight dry air. Humidifiers help prevent dry skin, keep hair and scalp healthy. Photo: Healthline. But you can also improve the air quality in your room by using a humidifier. As a result, the air does not take away water from your skin. In addition, it also helps keep your throat and mouth from drying out easily. Quick beauty tips for men If the beauty items suddenly run out, take advantage of available ingredients in the kitchen to “fire fighting”.

Photo: INA FASSBENDER | AFP | Getty Images Policymakers are under increasing pressure to fulfill the commitments of the Paris Agreement ahead of COP26 in Glasgow, Scotland, November 2021. Politicians and businessmen acknowledge the need to transition to a low-carbon society, but slowing global warming and meeting global goals of reducing emissions is increasingly so difficult. According to the director of the International Center for Environmental Law Carroll Muffett, the energy transition is going too slowly from a climate change perspective, but most importantly the acknowledgment of the problem is mainly willpower. political and economic options. World leaders and business sectors repeatedly reiterate their commitment to “transform the energy”. Nearly 200 countries have ratified the Paris Agreement on Climate Change, unanimously pursuing efforts to limit global warming to 1.5 degrees Celsius. This continues to be the main focus of COP26, albeit one Some climate change scientists say that now this goal has been “unattainable”. The Intergovernmental Panel on Climate Change (IPCC) thinks that between 2030 and 2052, the global temperature will get 1.5 degrees C hotter; To reduce global warming, it is necessary to reduce carbon emissions by 45% by 2030 from 2010 levels, before reaching net zero emissions by 2050. The problem is not that there is no technology or the ability to transform, or economic choice, but the structure of power and support for an industry that will decline. The emissions balancing strategies of some Governments and companies still depend on the increasing use of fossil fuels in the “coming decades”. According to Carroll Muffett, this reality can be seen in US policy, particularly in the plan to invest heavily in carbon capture and capture. The road is bumpy ahead . According to the US National Oceanic and Atmospheric Administration, the Earth’s carbon level is higher than at any time in the past 3.6 million years; If the worst effects of climate change are to be mitigated, it is important to focus on reducing fossil fuel emissions and studying how to prevent greenhouse gases entering the atmosphere. Burning fossil fuels such as oil, gas and coal releases large amounts of carbon into the air. Fossil fuel emissions and industry accounted for 89% of global emissions in 2018, the IPCC says. The US Energy Information Administration projects that global carbon emissions from fuel sources will continue to increase over the coming decades. According to energy finance analyst Clark William Derry, the current “energy transition” process is like the “transition of energy systems from the 19th century to the 21st century”; transition is taking place but it is not clear whether it is fast enough to prevent the worst consequences of climate change, fast enough to improve air quality in cities in developing countries such as in India, China, Bangladesh, Vietnam as well as some other countries; The road ahead is very bumpy. Is the current essential issue . The IPCC Intergovernmental Group notes that the transition from fossil fuels is underway and will require “rapid, far-reaching and unprecedented” changes in all aspects of the commune. festival. However, the February 2021 United Nations report showed that countries’ commitment to reducing greenhouse gas emissions was “far from” compared to the far-reaching measures needed to avoid the dire consequences of Climate Change. Currently only 75/195 countries have signed the Paris Agreement on climate change, submitting the National Contribution Plan (NDC) on emissions reductions to 2030. USA, China and India, are emissions countries. The world’s largest has yet to release its own NDC. United Nations Executive Secretary on Climate Change Patricia Espinosa urged policymakers to “accelerate” ambitious plans to cut emissions by 2021, emphasizing it as “crucial. ” The current./.

To keep your house cool in the Vietnamese climate, first of all, is the layout of the space, the location of light, reasonable wind, and ventilation thanks to open spaces. In addition, the selection of materials also helps to reduce some of the heat. Currently, there are materials on the market that can provide both sound and heat insulation well. Here are some suggestions of architect Bui The Long CTA | Creative Architects about materials that make your house cool year round. Use unburnt lightweight bricks You can use types such as block bricks, unburnt light bricks to help reduce environmental pollution. Solid brick walls, raw and un-painted brick walls also provide good insulation. Soil wall from mountainous ethnic people is now sought by many professional construction companies to apply in construction is also a worthwhile solution in the future. “Breathing brick wall” The use of “breathing brick wall” is also an option. “Breathing brick wall” includes a garden layer of 1.2 – 1.5 m combined with open brick wall, burnt brick built in the direction of continuous brick hole. From there, creating natural air inlets to help ventilate continuously 24/24 for the house. The less building layers of a wall surface, the quicker it heats heat, limiting heat retention, and heating indoor air. Spatial architecture with many layers of side corridor walls is also a method of limiting heat. Roofing tiles The roof is a part of the project that is subject to a considerable heat impact. Roofing with tiles or insulated corrugated iron will dissipate heat better than roofs made of concrete and tile due to the air space between the roof and the ceiling. For light-absorbing glass materials, in order to reduce heat, in addition to the way of insulating film, insulating glass is a good choice with no difference in price. Glass roofs or windows, doors should incorporate slots, ventilation bars to contribute to indoor air circulation. The glass wall material that has air insulation inside the brick is a material that is in common use. Wooden materials Solid wood materials limit heat gain, high inductance but relatively high cost, as well as longevity requirements, durability, so the use accounts for a low proportion of the common materials. The wooden houses have distinct beauty, cooler temperatures than concrete houses are many people love. Depending on the financial size of the homeowner can be considered to design. Using water surface or planting trees to cover walls or roofs, trees in the house is also a natural solution to help reduce heat and cool the house.

I don’t know if you have seen a video similar to “Glass Marble Making”.

In the video, the worker master needs to heat the glass material at a high temperature and then quickly shape it in a fluid state.

Although we are across the screen, we will also sweat for the operator. After all, the bright brightness makes it very hot to look at!

However, a recent study by Science shows that Now it is possible to inject glass under low temperature conditions!

Frederik Kotz and Bastian E. Rapp of the University of Freiburg in Germany proposed a high-throughput injection molding process using silica nanocomposites.

They combined the low-temperature injection molding process (IM) with water-based degreasing and low-temperature sintering processes to develop a new glass processing technology compatible with injection molding technology, which can quickly mass produce high-precision glass products with smooth surfaces.

Processing glass is not that simple

This technological breakthrough can be said to solve the core difficulties of the current glass processing industry.

first of all, High temperature melting, castingIt has always been a problem that plagued the glass processing industry.

The high temperature requirement above 1500℃, on the one hand, causes huge energy consumption during processing (It is estimated that every ton of glass processing needs to consume 5-6 megajoules of energy); On the other hand, to a certain extent, it limits the capacity and efficiency of glass industrial processing.

Secondly, the processing of glass micro-morphology mostly uses hydrofluoric acid, laser etching, etc. The preparation process is dangerous, difficult to operate, and pollutes the environment. The shape and output that can be processed will also be limited.

How to achieve?

However, Markus Mader and others used a low-temperature injection molding process (IM) combined with a water-based degreasing and low-temperature sintering process, which just solved the above problems.

Technical core—— Injection molding process (IM)It is a kind of rapid processing technology suitable for industrialized production. It finally produces a semi-finished product with a certain shape by pressurizing, injecting, cooling, and detaching molten raw materials.

Previously, this technology was mostly used in the processing and production of polymers. This time researchers have applied it to glass processing in a breakthrough.

First, the researchers pre-mixed silica nanopowder, vinyl butyral (PVB) solution, and vinyl butyral (PEG) solution, and evaporated to obtain a thermoplastic silica composite.

Then use a twin-screw extruder to plasticize and extrude the obtained material to obtain granular raw materials;

Followed by 130°C, Injection molding at a specific pressure of 700 ~ 1000 bar, obtained Green bodysection;

Soak the green body in water at 40°C first to remove the PEG from the material, and then use high temperature to remove the remaining binder;

Finally, high-quality transparent fused silica glass is obtained by sintering in a vacuum environment at 1300°C.

Due to the optimized two-step degreasing process, the injection molded green parts (less than 2 mm in size) are converted to transparent fused silica, and only a total of 24 hours.

In addition, the researchers further used the technology to perform high-throughput manufacturing on a commercial injection molding machine (Babyplast Christmann).

It was found that even if the silica nanocomposite is fully automated injection molding with a cycle time as low as 20 seconds, it is possible to produce complex-shaped fused silica parts at the industrial production level.

More than 200 parts were produced in 18 minutes, which means One glass component can be produced every 5 seconds!

Not only that, the energy consumption of the whole process Less than 60% of traditional processing technology; And because the degreasing process is not carried out in a high temperature environment, the adhesive used in the process can still recycle and re-use.

△Frederik Kotz

Researcher Frederik Kotz said: “This method can finally get high-purity silica glass of any shape.” And said that these glass parts will eventually have Commercial telecommunications equipment and chemical reactorsThe required optical and chemical properties.

△André Studart

André Studart, a materials scientist at ETH Zurich, said that this method can lead to more new ideas.

However, he proposed that this new method of mass production of glass components still faces a bottleneck: The PEG removal process takes several days, To ensure that the glass parts will not crack.

“If this process is accelerated, glass injection molding will become as popular as plastic!”

The way eggs are processed can affect the nutritional profile. Low-time and low-temperature cooking methods cause less cholesterol oxidation and retain most nutrients.

For this reason, boiled and poached eggs are the healthiest way to eat. This method of processing also doesn’t add any unnecessary calories.

Processing eggs makes it easier to digest certain nutrients

Cooking eggs makes this food safe and makes it easier for you to digest the nutrients inside them. In fact, one study found that the human body can use 91% of the protein in cooked eggs, compared with 51% in raw eggs.

Digestibility changes occur because heat leads to structural changes in the protein of the egg.

Eggs are also a good source of biotin, which is used in the metabolism of fats and sugars.

In raw eggs, a protein in the white called avidin binds with biotin, preventing your body from using biotin.

However, when an egg is cooked, heat causes the structural changes of avidin, making it less effective at binding with biotin. This makes biotin easier to absorb.

Cooking at high heat can spoil other nutrients

While cooking eggs makes some nutrients easier to digest, there is a risk of destroying others.

Cooking most foods will deplete some of the nutrients, especially at high temperatures, over long periods of time.

One study found that cooking eggs reduced vitamin A content (17-20%), significantly reducing the amount of antioxidants (6-18%).

Overall, shorter cooking times (even at high temperatures) have been shown to retain more nutrients.

When cooked for 40 minutes (baking), eggs can lose up to 61% of their vitamin D intake, compared with 18% when fried or boiled for less time.

However, even when cooked reduces these nutrients, eggs are still a rich source of vitamins and antioxidants.

Cooking at high temperatures oxidizes the cholesterol in the eggs

One large egg contains about 212 mg of cholesterol, 71% of the recommended amount of 300 mg per day.

When eggs are cooked at high temperatures, the cholesterol in the eggs can be oxidized and form compounds called oxysterol. This is a concern for some, as oxidized cholesterol and oxysterol in the blood are linked to an increased risk of heart disease.

Tips to cook eggs with health benefits:

1. Choose a low calorie cooking method

If you’re trying to cut calories, choose boiled eggs or poached eggs.

These cooking methods do not add any fat calories, so the meal will be lower in calories than an omelet.

1. Combine with vegetables

This is a great opportunity to increase vegetable intake and add fiber and vitamins to your diet.

Artwork: Meatmerchant

1. Fry in oil that is stable at high temperatures

The best oils for cooking are those that remain stable at high temperatures and are not susceptible to oxidation to form harmful free radicals.

Examples of good options include avocado and sunflower oils. If using extra virgin olive or coconut oil, it’s best to cook at a lower temperature than the last time.

1. Choose the most nutritious eggs possible

Several factors, including the method of farming and the diet of the chicken, can affect the nutritional quality of the eggs.

In general, eggs from hens raised in pasture and organic eggs have a higher nutritional value than eggs from industrial hens.

1. Don’t overcook

The longer you cook the eggs and the higher the temperature, the more nutrients you lose. This habit can also increase the amount of oxidized cholesterol in the eggs.

An Yen (According to Healthline)

Korean experts explain that, because milk has a form of protein called casein, hot temperatures will be joined together and form a coating on the surface of the pan.

The way to refresh the non-stick pan with fresh milk is quite simple, first, you pour some fresh milk into the pan. The amount of milk is enough to cover the entire pan.

Next, you boil the milk to a full boil for 5 minutes. Be sure to keep the fire on fire so that the milk won’t spill over and contaminate the kitchen. Then, you discard the milk (can be used to fertilize the plant but not for drinking). Then you use clean water to wash the pan to remove the remaining milk on the surface of the pan.

Illustration.

Note: This method only applies to pans with moderate peeling, if all the non-stick layer is peeled off, the effect is no longer noticeable.

Note using the non-stick pan so that the pan will last as long as it is new

When frying, only use a sufficient amount of grease

Conventional pans will need a lot of grease for the food to cook evenly and not to burn. However, with the non-stick pan, you should only add a sufficient amount of oil because it prevents the food from sticking.

Using less grease is both economical and healthy, good for the longevity of the non-stick pan.

Oil should be added when the pan is not too hot

The non-stick coating that encounters high temperatures in dry conditions will easily peel off, affect the quality of the dish and not good for human health.

Do not season with salt seasoning when the pan is on high

Did you know that seasoning salty spices (such as fish sauce, salt, …) when the pan is cooking at a high temperature will make the surface of the pan pitted, the non-stick layer is easier to peel.

Use a wooden utensil to stir food in a non-stick pan

Wooden mixing objects will not scratch the surface of the pan like metal tools (aluminum, stainless steel).

Do not let the fire get too loud

At high temperatures, the non-stick coating in the basin can degrade and cause health risks. Therefore, you should keep the fire low or medium to ensure the safety of the family and ensure the durability of the pan.

Do not use the pan for baking, storage, …

Baking and storing at high temperatures can cause the non-stick coating to peel off, reducing the durability of the pan.

Red tree bark flattened beetle

This beetle about half an inch long has a habitat from North Carolina to the Arctic Circle. They live under the bark of a tree and their bodies are purposefully designed to survive the harshest conditions in mid-winter.

The arctic climate in August acts like the resting climate for this species. In laboratories, they can withstand freezing temperatures up to -150 degrees Celsius.

In fact, this is the coldest we’ve ever seen. They can overcome this extreme cold by forcing 30-40% less water in the body and preserving the remaining water by using antifreeze proteins between the cell membranes.

Thyme beef

Muskrats have lived in the Arctic for a long time, from the ice age about 200,000 years ago. With double-layer coat, the first layer is a thick dark gray outer coat that reaches the ground long and the inner undercoat gives them very good resistance to cold to temperatures down to minus 40 degrees. , to withstand the rigors of the Arctic.

Muskrats live in herds from 12-24 in winter and 8-20 in summer. During the summer, musk cows live in humid areas, such as deep valleys, and move up into higher mountainous regions in winter. Their food includes arctic willow grass, lichen and moss under the snow. Thyme is raised for meat, milk and feathers. Currently this species is protected, so the number is kept at a stable level.

Great Greenland shark

The Greenland giant sharks live in deep waters in the North Atlantic and Arctic regions, and these giant sharks not only survive in the cold water, but also have the longest lifespan of any species. are there any vertebrae on the planet – an average of 300 to 500 years old.

Greenland giant sharks have an extremely slow metabolic rate that helps control temperature and prolong life, and they are also the largest shark, can reach 6.4m in length and weigh about 1,000kg . Therefore, this shark is also very slow, often only hunting prey that has gone to sleep.

The price for a 500-year-old shark’s longevity is also not small. Specifically, it not only swim very slowly, difficult to find food, but the body also contains many parasites. Sometimes it even has to eat scavengers to relieve its hunger.

Besides, scientists are also hoping, the study of 500-year-old shark’s DNA could open a way to longevity for humans.

Before that, indigenous people in Greenland and Iceland used to believe in increasing longevity by eating Greenland shark meat.

Greenland shark meat is considered a specialty in Iceland, although toxic if not handled properly.

Snow Sheathbill

The snow Sheathbill is a brave, white, dove-like bird; This is the only native bird that lives on the surface of Antarctica and is the only species to breed here.

With their thick fur to help keep them warm, they live mostly on the ground, trying to pick up other birds’ scattered food scraps. They are also the only birds in Antarctica that do not have membranes.

So how can the snowy Sheathbill keep his toes warm while spending so much time on frozen ground? The secret lies in their life-long “bounce hobby”, they spend a lot of time hopping from leg to foot in order to reduce the coldness from the surface of the ice and snow. Furthermore, Snow Sheathbills also possess an extremely thick, fine coat that helps them retain heat well.

Weddell seals

If you are looking for a mammal that loves a few dozen degrees of negative cold every minute, then you will definitely love the Weddel seal.

They are the farthest Antarctic species of any kind, and spend most of their time living underneath the Antarctic ice, where they can hunt and avoid being caught by killer whales.

With the ability to dive deep to a depth of more than 600 meters, Weddell seals can stay underwater for up to 45 minutes and if they cannot break the ice to get the oxygen they need, they use their teeth to dig a hole. take the gas.

Antarctic seawater is actually warmer than surface air (which can drop to -70 degrees Celsius), so especially during intense winter storms, seals will stay warm by diving into the ocean. .

The arctic soil squirrel

If the current epidemic in the world makes you want to hibernate, you can consider the Arctic ground squirrel as an example.

Living in the arctic tundra in North America, where temperatures can drop below -63 degrees C in winter, they can escape the coldest winter by burrowing underground and sleeping for as long as eight. the month of the year.

When hibernation, the temperature in the brains of these squirrels can drop to just above freezing, while the body temperature can drop to -2.9 degrees C and the heart rate drops to just one beat per beat. minute. When the hibernation time is over, the squirrels need about three hours to warm up the body again.

This ability of arctic ground squirrels is due to them being able to cut off nerve connections and synapses to hibernate, then reconnect them immediately after awakening and warming the body, almost 2 – Every 3 weeks during winter.

In addition to its sublime cold tolerance, the arctic ground squirrel is also famous for its ability to fast for 8 months. The arctic ground squirrel body has the ability to recycle its own nutrients during hibernation for many months.
