Sunfish “invaded” Sichuan?Small but “ruthless character”, netizens have posted recipes Recently, the news that an exotic species of sunfish has invaded Sichuan has been confirmed by relevant departments: Sunfish have indeed appeared in Sichuan, but the number is not huge and will not be flooded for the time being. In this regard, many netizens are curious, are sunfish delicious? Can it be prevented by eating?

“The thorns are less like sea fish. The’garlic clove meat’ we call out is very delicious.” A fishing friend said that the sunfish are both deliciously braised and steamed. There are several relatively large reservoirs in Sichuan, as well as the urban areas, including Jinjiang Park and Donghu Park.
The staff of the Fisheries Research Institute of Sichuan Academy of Agricultural Sciences said that sunfish can be eaten, but it is definitely impossible to rely on eating to prevent flooding. In addition, there have been examples of artificial breeding of alien species for food before, such as the commonly known “barracuda”, its scientific name is channel catfish, which is native to the North American continent, and was later introduced into the country and realized artificial breeding for food. .

25 yuan a catty sold in the vegetable market
According to the boss of Guangming Road Caishi Aquatic Product District near Niuwang Temple, the sun fish is 25 yuan a catty. “Braised in braised or steamed, it’s still a bit worse than sea bass, the meat is not that fine.” The fish seller said.
Regarding the price of sunfish at 25 yuan a catty, some fishing friends said that sunfish may be expensive because it grows slowly. Crucian carp and carp can grow to half a catty in less than a year, and sunfish for several years. The biggest he has ever seen is only 7 or 8 taels. At the same time, sunfish has few small spines, like sea fish, commonly known as “garlic meat”, braised and steamed are delicious.
Both Jinjiang Park and Donghu Park in Chengdu
It is reported that sunfish is a freshwater fish native to the freshwater waters of the southern United States and northern Mexico. As the name suggests, most sunfish are brightly colored. After entering the natural waters and hybridizing, its color gradually fades, resembling a crucian carp. The spiny fin on the back is an obvious sign. It is greedy and ferocious, and can survive in water temperatures of 1℃-38℃. Even if the surface of Sichuan’s natural waters is frozen, the water temperature below it is above zero. As far as temperature is concerned, it is more suitable for sunfish to survive.
“There are several relatively large reservoirs in Sichuan, including Luban Reservoir and Sancha Lake.” According to a fishing friend, Chengdu also has Jinjiang and Donghu Parks. What needs to be reminded is that it is currently in the spring ban in Chengdu, and sport fishing is prohibited in natural waters. Although sunfish is an exotic species, it cannot be caught.
How can sunfish native to America appear in Chinese waters? The relevant person in charge of the Sichuan Fisheries Bureau said that disorderly release is the main way for alien species to invade, and captive breeding is also one of the sources. In natural waters, there are strict restrictions on whether it is official multiplication release or private release. In the case of floods during the flood season, the artificially reared alien species may also “sneak away” into natural waters. In addition to adults, such as fish eggs, it is also easy to follow the water into natural waters.
There is a precedent for the introduction of artificial breeding of alien species for food
Since it is a food, is it feasible to prevent it from spreading by eating it? “It’s definitely not enough to rely on everyone to fish for food. The amount is too small.” The staff of the Fisheries Research Institute of Sichuan Academy of Agricultural Sciences said that at present, the Yangtze River is banned from fishing and the annual fixed period of fishing is prohibited, and productive fishing cannot be carried out. Even in areas outside the ban on fishing, it is difficult to prevent sunfish from flooding by fishing. The simplest question is, who can guarantee that all sunfish are caught.
In fact, there are already artificially raised sunfish in China. Sunfish was introduced into my country’s inland farming in 1987. At present, large-scale farming has been realized in Guangdong, Fujian, Zhejiang and other places, but Sichuan has not yet. The staff of the Fisheries Research Institute of the Sichuan Academy of Agricultural Sciences said that the barracuda that everyone called is actually an exotic species. Its scientific name is Channel Catfish, which is native to the North American continent and was later introduced into China and cultivated for food. Everyone may eat it artificially, so eating and preventing it from spreading are not really relevant.
Strictly manage artificial breeding to prevent flooding
How to prevent sunfish from flooding? “Although there are a lot of exotic species, not many have truly become the dominant species,” explained the relevant person in charge of the Sichuan Fisheries Bureau.
At the same time, the relevant staff of the Fisheries Research Institute of the Sichuan Academy of Agricultural Sciences said that related science popularization and strict management of artificial breeding of exotic species are very important. At present, there are more and more non-governmental release activities. Although the amount of individual release may not be much, it is widely scattered. By reducing the artificial release of alien species through science popularization, the risk of alien species invasion can be reduced. At the same time, artificial breeding is just the opposite. The amount is larger and more concentrated. It is necessary to strictly abide by the relevant regulations to ensure that artificial breeding of foreign species does not enter natural waters.

This lotus lagoon is located about 14 km from the center of Hanoi. Coming here, visitors will be surprised to see hundreds of types of lotus flowers and water lilies blooming… Located at lane 234 Ngo Xuan Quang, Trau Quy town, Gia Lam district, this is the Center for experiment, research and development of lotus genetic resources managed by Mr. La Tien Hiep (pictured). Center under the Vietnam Academy of Agriculture. The center was established for the purpose of researching, conserving, breeding, and developing lotus varieties in Vietnam and around the world, and developing the Vietnamese lotus brand. (Photo: Trung Hieu) The lotus pond is about 7.7 hectares wide, which is the place where the most lotus species are grown in Vietnam today, said Hiep, who has many years of lotus research. Here, we are researching and breeding new varieties of lotus that have many advantages such as keeping the fragrance longer, having a variety of rich colors, and being able to grow in harsh weather conditions in the North. (Photo: Trung Hieu) This is also a place for everyone, from the people to the students of the Agricultural Academy, to visit and learn about different types of lotus… (Photo: Trung Hieu) La Tien Hiep said, the Center was established in June 2019. After 2 years of development, the Center currently has 167 species of lotus. (Photo: Trung Hieu) Here are planting and conserving precious lotus species of Vietnam and the world, from famous lotus varieties of localities in the country such as Hue, Dong Thap, Cu Chi… to lotus species from China and some countries. Asia, Australia… (Photo: Trung Hieu) The center provides to the market 8 species of lotus such as blood lotus, white lotus, white rose bordered … with thousands of flowers sold every day to serve the needs of people to play flowers, arrange flowers, enjoy lotus tea of ​​people. People in the capital – Mr. Hiep said. (Photo: Trung Hieu) The lotus pond is open to visitors to visit and learn about lotus. Many people in the capital come here to see and take pictures at the lotus pond at the weekend. However, at this time, visitors must ensure the 5K request from the Ministry of Health to be allowed to visit and take photos. (Photo: Trung Hieu) Because the lotus dress is wide and airy, ensuring a good distance, women can comfortably relax and pose on the lotus side.

Lungfish (Scientific name is Salamanderfish) is a freshwater fish famous for its ability to live on land. They can live for months without swimming around in the water, even years. The reason is that, with normal fish, the bubble is the part that helps the fish keep balance when swimming. But in lungfish, the bubbles develop into lungs to take oxygen directly from the air. Their fins also gradually change into swimmers. In the presence of water, lungfish swim normally, eating fish and small crustaceans. When the dry season comes, these places run out of water, lungfish will burrow into the mud by eating mud with their mouths and then excreting through the gills. When they reach a sufficient depth, they secrete mucus through their mouths to harden the mud, forming a cocoon around it. The mouth of the fish is the only part that is exposed to the air. Electric eel (electric eel) is a dangerous “water monster” in the Amazon River. They have a special ability, which is to generate electric current from cells called electrocyten located on the side. This current can reach 600 volts, enough to knock down a horse. Many electric shocks from this creature can cause heart attack or respiratory failure in humans. When attacked by electric eels, normal people will be stunned and drowned. Electric eels locate their prey by generating 10 volts of electricity before stunning them and killing them with stronger currents. Clownfish (clownfish) has an orange body with three white stripes. Most of them live in shallow waters in the Indian Ocean, the Red Sea and the western Pacific Ocean. According to the Mother Nature Network, clownfish are hermaphrodites with the ability to reproduce like both males and females. An interesting fact is that up to the right size and condition, clownfish will have the ability to change sex. Specifically, in a school, only the two largest clownfish are responsible for the reproductive function, they are the only couple in the school. If the dominant female dies, the male leader will change sex and become a breeding female. The second largest male will quickly develop into an adult male to pair with a new female. Siamese fish is one of the popular fish in Thailand. Possessing a variety of colors and beautiful round fins, Siamese fish are loved and kept as pets by many people. Besides the colorful appearance, Thai Siamese Siamese fish is also impressed by its unique ability to change color. The color of this fish’s body will change according to the environment, even if their mood is not good. Siamese fish is also known as an intelligent fish. They can be taught to swim with their fingers or push the ball into gold. They are also known to be aggressive and are often used in “fish fights”. Barrel eye fish (Scientific name is Macropinna Microstoma) is a strange fish with tubular eyes, located on the inside of the head and protected by a transparent shield filled with liquid. Their eyes are sensitive to light and contain a green pigment, which helps the barreleye fish to survive in the deep sea when hunting and hiding from predators. These eyes are even rotatable, allowing them to look straight ahead or look up to see everything overhead. The barreleye fish lives in the deep seas of temperate and tropical regions of the Atlantic, Pacific and Indian Oceans. They spend most of the day maintaining a fixed position in the water thanks to their large flat fins. Devil face fish Verrucosa , also known as coral fighting fish, are commonly found in coral reefs under Australian waters. Their bodies can be up to 50 cm long and possess 13 venomous spines on their backs. The venom of the devilfish can cause heart failure if humans accidentally touch its venomous spines. In addition, the devil face fish also has a large body, many fins on the back and rough red-brown patchy skin like rocks. Taking advantage of this advantage, they often hide in coral reefs to hunt. After identifying its prey, it launches a bite in just 0.015 seconds to swallow the opponent.

Overexploitation The researchers analyzed DNA to test eel products, including grilled eel and sushi, sold in restaurants. The results recorded that nearly 50% of the samples were identified as European eels (Anguilla anguilla) on the endangered animal list. This species is threatened by overexploitation due to increased consumer demand from Asia, especially China and Japan. These two countries consider eel a delicacy and aphrodisiac. Critically endangered and endangered eels are being sold in sushi restaurants in Hong Kong. Photo: South China Morning Post. European eels are listed in Appendix II of the Convention on International Trade in Endangered Species (Cites). The Ordinance for the Protection of Endangered Species of Fauna and Flora requires an export permit and inspection of the species upon arrival in Hong Kong. Of the 80 samples, 36 were confirmed as critically endangered European eels, 29 were American eels, and 5 were Japanese eels. Critically endangered European eel is sold in 45% of the 80 sushi restaurants surveyed in Hong Kong. Photo: South China Morning Post. Gap The World Wide Fund for Nature (WWF) said the results showed the animals were illegally existing in Hong Kong’s eel supply chain. The organization calls for urgent action to stop the illegal wildlife trade. To this day, Hong Kong remains one of the biggest hubs for the illegal wildlife industry, with a record number of wildlife seizures. In February, HKU published a study showing that thousands of species are legally trafficked through Hong Kong with inadequate traceability. At the heart of the problem lies a vague code system that customs officials around the world use to classify species. “The codes used for the eel trade are too general and only list products that are goods of the Anguilla species. However, those codes do not distinguish between different Anguilla species and their life stages,” said Jovy Chan, wildlife conservation manager at WWF. “Complete, specific and accurate commercial data are important to facilitate the implementation of conservation policies for eel species. In addition to European eels managed by Cites, some parts of Asia, for example the Philippines, Indonesia and Taiwan, have bans on the trade in European eels. Customs codes have a key role to play on issues of legality, traceability and sustainability of eels,” added Ms Jovy. David Baker, staff member of HKU’s Conservation Forensic laboratory and who led the eel study, said the results reflect the vulnerability of the retail market. “Our hope is to partner with WWF. This enhances surveillance at distribution points to prevent illegal seafood products from entering the market,” Mr. Baker said. A fisherman releases a Japanese eel in the Enshu Sea off Hamamatsu, Shizuoka Prefecture. Photo: South China Morning Post. In 2020, HKU published a study showing that nearly half of eel products retailed in supermarkets and convenience stores in Hong Kong are endangered European eels. Based on DNA testing, the study found that nearly half (45%) of retail eel products originate from critically endangered European eel species. Products are only labeled as “eels”. “Consumers have the right to know where their food comes from and whether it is sourced in ethical and sustainable ways. This problem is not limited to eels,” Mr. Baker said.

How did you start raising awareness about the endangered rhinoceros species? I have been involved in many activities to raise awareness about the urgency of the rhinoceros species. I was still playing cricket for England at the time and my tools and things had a lot of rhinos on them. After that, many people expressed interest in buying the items again because they looked cool, and that’s how I competed to raise awareness. Later, I used my son’s drawings of rhinoceros on the competition equipment as well as the main logo of SORAI. The drawing appeared on hats and t-shirts and received a very good response, so I thought about the next step of developing and building the organization. Kevin Pietersen and Ms. Petronel Nieuwoudt – founders of Care For Wild, the largest rhinoceros orphanage and sanctuary in the world Can you share more about the operating mechanism of the organization? We donate 20% of our profits to conservation and do our best to save endangered animals. That is the purpose of our activities and when buying our products, people also contribute to a great cause. We don’t want people to see us as a charity asking people to donate money. We have a donation page where people can contribute directly to causes you believe in. Or you can also become an ambassador, support activities related to our products, and also be the subject of discussion. It’s a way to create exchanges, thereby raising awareness across the board, with us in our efforts to stop the illegal wildlife trade. What do you think about rhinos that the public needs to be more aware of? Rhinos are in danger of extinction. In South Africa, in the last 10 years, we have lost two-thirds of the remaining rhinos here. The problem stems from black markets such as China or Vietnam, which have engaged in illegal wildlife trade activities. Africa would not be Africa without rhinos. They are one of five important wildlife species in this place. We stand firmly against the illegal wildlife trade and also rhino horn. Many texts have asserted that rhino horn has no medicinal value, and that greed and misinformation in society have used them to flaunt their status. These things need to be removed immediately! And how did the collaboration between SORAI and Hublot begin? In 2019, while the Cricket World Cup was in progress in England, Hublot and I started working together. Then we did bigger things together, and we really brought about change. The first Big Bang Unico SORAI watch was born at that time and immediately “sold out” very quickly. The feedback after that was also very positive and everything was perfect. And I believe this next watch will achieve the same success. The new Big Bang Unico SORAI watch will be released in 2021 Can you share with everyone about the similar values ​​of SORAI and Hublot? I think time is the greatest value we share with each other. Quite simply, Hublot offers very innovative timepieces. And together we are in a race against time to save the rhinoceros from extinction. This is a perfect collaboration! SORAI and Hublot’s first collaboration was the very successful Big Bang Unico SORAI watch. Can you share more about the achievements after that initial success? If it weren’t for that success, I probably wouldn’t be sitting here talking to you right now. The opportunity to approach and talk about the organization’s activities with the public in Vietnam is a wonderful thing. For me it is a very meaningful success, besides financial success. Big Bang Unico SORAI watches come with 2 sets of bands with matching colors màu What’s different about the second Big Bang Unico SORAI watch released in 2021 compared to the first one? The new Big Bang Unico SORAI is equipped with a UNICO manufacture movement and is inspired by the natural colors of the woods in summer: a harmonious blend of two greens, from the green ceramic case. tree to the camo green hue of the familiar rubber or Velcro strap. This special edition, with the SORAI logo engraved on the sapphire crystal back, is limited to just 100 pieces worldwide. Due to the impact of the pandemic, we worked together through video meetings, coming together to agree on every detail on the new watch. SORAI’s black rhino logo on the dial After working with Hublot for a while, what percentage of your initial expectations about this relationship have been met? What I expect is all that we have achieved so far. We have an organization that works for the sake of bringing about change, raising large sums of money from the profits of the first 100 watches sold for the activities of the organization. More importantly, thanks to this cooperation, I have been able to reach other countries and territories. This is like a marking exercise, every opportunity we have to raise awareness of the community, to be communicated to the public, can open certain doors. Thank you for taking the time to chat and share! Perform: Tuan Anh

Xuan Huong was born and raised in Vietnam. Then she immigrated to America. Currently, she enjoys the housewife life, taking care of her family and unleashing her passion for all kinds of quince in her garden. Ms. Huong shared: “ Before, I planted a lot of flowers, I like to plant for fun because my house is quite large. At first, I did not grow Quynh but planted a variety of varieties such as roses, chrysanthemums… However, realizing that other flowers take a lot of time to care for, prune, and water daily, I decided to choose primrose, which is both easy to care for and blooms brilliantly. I usually focus on taking my kids to school, cooking, and spending more time with myself “. Previously, she also tried to grow many different types of flowers such as chrysanthemums, roses… However, most of the flowers she planted need a lot of time to take care of. Therefore, she has researched and chosen to plant varieties of rhododendrons, flowers that bloom brilliantly but don’t take much care. Her garden is therefore always lush and impressive. A corner of rhododendrons is blooming brilliantly. Ms. Xuan Huong beside the blooming sunflowers. Initially, Ms. Huong planted a few varieties of rhododendrons and found this to be a suitable variety for warm climates. The tree also has many colors, flowers bloom beautifully, is durable and does not require much care. Up to now, Ms. Huong’s garden has more than 200 different types of Quynh. The more I grow, the more I love it, so I don’t stop buying more of my favorite varieties to plant. Among all types of Quynh, my favorite is Quynh sen (German Empress) because the flowers bloom for the longest time compared to other types of Quynh. Each flower can bloom for about 7 days while other types of rhododendrons only last 2-3 days. The color of the flowers is similar to that of Vietnam’s lotus bud, so every time Quynh blooms, she misses her hometown more. A brilliant garden corner, showing off her fragrance with the types of Quynh that she loves. The characteristic of Quynh is that it likes light sunshine, under a sheltered place, little watering, dry soil. Quynh blooms can be fresh for up to 1 week, helping her garden always shine very impressively. One corner is placed a lot of potted rhododendrons with different varieties. Ms. Xuan Huong currently grows more than 200 types of quince in her garden. In her spare time, she still spends her time collecting different types of rhododendrons to plant in her garden. Flowers are also quite diverse in color. In her spare time, Ms. Huong often walks around the garden, with time on the weekend she will take advantage of watering more fertilizer. She often plans with a periodic irrigation schedule. On average, she fertilizes flowers once a month. In winter, she gives the plant a break without fertilizing. In the summer, she watered every 3-4 days, in the winter because it was cold, the plants kept moisture well, so she only watered once every 10 days. The owner of the garden shares the secret of flower care: “If I want flowers to bloom beautifully, I usually add bloom booster to promote more flowers. In terms of soil, I plant cactus soil or potting soil that is easy to drain. I don’t like to water a lot, if the soil is moist enough, the plant can grow well. “. Quynh is a flower that does not need much effort to fertilize, does not water a lot, sometimes adding fertilizer periodically is enough to enjoy the brilliant beauty of the flowers. In her free time, Xuan Huong often takes her children to the garden to take care of the sunflowers, learn about nature, and get closer to the trees. This is also the time when she feels happy, relaxed and loves her home and garden more. Thanks to these simple experiences, the garden of Ms. Xuan Huong’s family is always brilliant with all kinds of rhododendrons racing to bloom. I love every little corner of my garden. The charming types of Quynh stand out in the garden like a highlight creating a natural feature, close to nature, helping every member to love their home more every day.

Flooring can be grouped on the market into two main types: Natural wood flooring and laminate flooring. Types of flooring have many different origins, from domestic production to imports from European countries (Germany, Sweden…), in Southeast Asia (Thailand, Malaysia…) and most are boards. Wood flooring originated in China. The price of natural wood flooring is getting higher and higher due to the scarcity of raw materials and the inevitable trend of using laminate flooring. Wooden floors have many advantages such as clean, close, warm, convenient construction. For natural wood flooring selection, you can view a few random bars in the shipment to evaluate the product. Natural wood flooring products are good for flat, matte surfaces with few wood eyes; the edges are not chipped, scratched, the bar has no cracks…; Try to put the bars together and see that it fits your hand, not too tight and not too loose. In addition, some bars can be laid out on a flat surface to evaluate the uniformity of wood grain and color. Natural wood is harvested from many different sources of raw materials, so it is easy for different finished products (even though they are the same type of wood). If the user wants to use natural wood for a large and solid surface, this factor should be carefully considered to have a uniform surface finish. With industrial wood, there are many models on the market, so it is difficult to choose. Basically, the way to distinguish is not the same as for natural wood because laminate flooring is “one hundred bars like one”; It is important to know the origin. Quality-assured laminate flooring often has the brand name imprinted on the underside, and has the words “Made in… (name of country)” (eg Made in Germany), the print is clear and sharp. Laminate flooring has different technical characteristics related to cost. For example, if you choose a wooden floor for public spaces such as restaurants, supermarkets, etc., then choose a floor with high scratch resistance and roughness (to meet the needs of walking on shoes with frequency of travel). much). Appropriate spaces for use are usually indicated on the product’s packaging. It is necessary to check whether the edges of the bars are easily chipped or not. It is necessary to preview the price of the distribution company (if any) and consult the prices of several agents on a product to avoid buying at an unreasonable and expensive price. Besides, it is possible to mention some flooring materials that have the same functions, properties, specifications and construction process as wooden floors but with other materials such as bamboo floors, composite plastic floors. These types have the same common features as wooden floors but are manufactured with different materials, have different surface and grain forms and have different physical and mechanical properties. For example, bamboo flooring has a fairly high hardness, water-resistant plastic floors can be used for paving balconies, loggias, patios… These types of materials can replace wooden floors in each specific situation to exploit. exploit the optimum properties of the material. Using wooden floors in the interior space There are two basic ways to coordinate floor colors with furniture, that is, similarity and contrast. Basically, wooden floors are very similar to the interior space of houses, in addition to the preeminent features of functions such as cleanliness, proximity, warmth, convenient construction… However, it should be noted. some points for proper and effective use. Wood floors are generally not recommended for use on the ground floor because they are very susceptible to moisture, deformation and damage, as well as being easily penetrated by insects. The kitchen area should also not be used because it is easy to have water, as well as fire, which are unfavorable factors for wooden floors. Wooden floors are suitable for use in spaces such as living rooms, bedrooms, floor halls, hallways, etc., with little negative impact in daily life. The attic should also not use wooden floors because usually this floor is rarely used for living, is subject to hot sun, can be flooded with water, rain … Wooden floors can be suitable for both modern and classic architectural – interior spaces. However, it is necessary to pay attention to interior colors (wall paint, ceiling, curtains, furniture, etc.) to choose the appropriate type/color. If using natural wood, each type of wood has its own color. For example, iron floors have dark colors, pomu floors have light colors… Industrial floors have more diverse colors and wood grain elements, the color is only a part of the aesthetic, it does not determine the quality of the flooring. There are two basic ways to match the floor color with furniture, that is, similarity and contrast. With a similar arrangement, choose wood floors and furniture of the same color (maybe a little lighter than each other); In contrast, you can use dark floors, light furniture or vice versa (light floors, dark solid furniture). It is necessary to avoid dark floors and dark furniture because it will darken the space and not honor the furniture in the space. Many laminate flooring companies advertise super water resistant laminate floors. However, it should be understood that “water resistant” here is within a certain limit, but wooden floors – whatever it is, cannot be as water-resistant as ceramic tiles or natural stone. In order not to be dazzled by the “forest” of products on the market Wooden floor “hundreds of flowers bloom” on the market of building materials. Therefore, to choose real wood flooring is not easy either. Customers should actively seek out reputable companies and suppliers with good warranty regime to search and choose products. With laminate flooring, quality is paramount. In addition to choosing the type of flooring to ensure quality, choosing the model (specification, pattern, color …) also makes sense. To have a beautiful interior space, it is necessary to have a professional eye and an expert voice for advice. When looking at the store, you can see a lot of beautiful models, but it is not certain that the model “goes” into the house, into the interior space is appropriate (and vice versa). The factors that need to be referenced and dominated are: interior style, floor plan, interior layout, style – color of furniture details, lighting conditions, etc. Usually these factors come before and decide. suitable floor pattern. Ideally, please provide the information and needs as mentioned above to architects and consultants to assist them in choosing the right flooring model. And do not let the sales people advise because they will lead with their purpose of selling the type of product they need to consume, rather than doing good for their home, and practically expert in wood flooring and professional expertise. Design is completely different.

The domestic paint market is diverse in types and models. Photo: Thanh Luan The race to attract customers The paint market has accompanied the development of the building materials industry and thrived in the last 10 years. With hundreds of brands from foreign to domestic, paint products are increasingly diverse in types, features, colors… Mr. Nguyen Tien Quan – owner of a paint agent on Phung Khoang Street (Nam Tu Liem, Ha Noi). Noi) said that the current paint market is a race to attract customers of domestic and foreign enterprises. From the “big guys” like Jotun, Dulux, Nippon Paint, 4 Oranges to many small and medium brands like Galaxy, Alex, Kavic, Joton, Jymec… are all trying to establish a foothold in the market, continuously. improved, diversified in types, features, colors… making the competition somewhat fierce.
For example, with AkzoNobel, the company’s main product line is Dulux Weathershield for exterior paint, Dulux 5 in 1 for interior paint, developed and applied cooling feature with reflective technology. Heat reduces the outside temperature of the wall compared to conventional outdoor paint. Or as Jotun Vietnam marketed anti-fading Jotashield exterior paint products, helping to prolong the time of repainting the house. Meanwhile, paint products Mykolor, Spec of 4 Oranges are integrated with environmentally friendly properties, do not contain lead, mercury…
However, according to market analysts, in the face of pressure from the “big guys”, domestic paint firms, although inferior, are not afraid to approach the market. The focus on research and development of unique features to make a difference has helped domestic enterprises maintain their brands, output, and customer market share. “For example, Kavic has launched the KA-388 interior polish product on the market, the KA-683 exterior polish is quite good, easy to install, very affordable. Besides, there are also anti-reflective paint products. KA-889 cement absorbent application Nano technology, waterproof feature, ultraviolet rays are popular “- Mr. Nguyen Tien Quan information.
Choose the right product for the function
Through reference, paint shop owners all said that the choice of water-based paint for both individual housing projects or large projects focuses on three factors: Price, quality and brand. Next, we will consider the advantages that paint brands bring (coverage, gloss, color, aesthetics and criteria such as anti-cracking, self-cleaning…), until the product line is approved. make sure to sign a contract to choose that brand. The price is also diverse for consumers to choose, on the market recorded ranging from 350,000 to 2,500,000 VND/barrel, depending on quality, good adhesion, easy to clean, anti-mold and body. environmentally friendly.
But depending on the geographical conditions, environment, weather and climate of each project, there will be appropriate paint products. The criteria for evaluating indoor wall paint are different from outdoor wall paint, so the same paint cannot be applied to evaluate good or bad. Therefore, consumers can rely on a number of criteria such as paints provided from reputable brands, sold at genuine stores. Water-based paint needs to ensure factors such as diverse and rich colors, good features, high adhesion, long-term color fastness, not affecting the user’s health as well as the environment.
Ms. Pham Hoa, owner of Phu Minh wall paint and construction agent, Linh Duong street (Hoang Mai, Hanoi) said that the trend of house paint colors this year is mostly in the direction of “tone – slick – tone” when The color of the furniture in the house is in harmony with the paint color of the wall, emerging 4 main colors, which are: gray, cream brown, dark blue and pastel blue. Gray color is for customers who love luxury for the context and decoration in the living space. With cream brown color will bring a sense of politeness, peaceful beauty, full of sunshine, like being illuminated by the sun everywhere in the house. Pastel blue or dark blue brings a feeling of coolness and relaxation, and at the same time brings a feeling of freshness, sophistication and aesthetics.
The growth of the paint market will be resonated with the recovery of the real estate market. When the market appears more and more manufacturing enterprises, the competition becomes more and more fierce, so customers have more choices. Most paint companies have launched many products with improvements in features and capacity at different prices to meet the needs of the increasingly vibrant building materials market. As more and more construction works, manufacturers also compete with each other to develop sustainable brands. Consumers also have many choices because of the variety of designs, colors, and decorative paints that have begun to invade the market before the rapidly increasing demand for use.

Trees help to regulate the indoor air. The house of Ms. Nguyen Thuy Trang (SN 1983 – Ho Chi Minh City) is located in the heart of District 5. From the noisy street, full of smoke and dust, entering here, you will be immersed in the open space, covered with green by trees mortar. With a house width of 8m, a length of 10m and a small yard, she takes advantage of all the sunlight and sunlight to grow fruit trees and ornamental plants to solve the problem of air pollution. Viewing angle from above. Thuy Trang bought the house 4 years ago. Due to the good structure of the house, she did not build a new building, but only renovated the rooms, increasing the functions and utilities. The garden was also researched by her, made from that time. The whole renovation of Thuy Trang is assigned to a design and construction unit. The project consists of 2 blocks linked together by a system of trees and light. Ms. Trang arranged the planting areas according to the characteristics of each type. Achievement after 4 years, the house is shady green trees. The green tree system not only creates a fancy beauty for the building, but also helps to condition the air, bringing a cool feeling to the occupants. Interior design is simple but still cozy and elegant. The pathways in the house are also filled with trees. Tree truss vertical on the wall. These are all trees suitable for tropical weather. All floors are arranged with big glass doors to catch the sun. The balconies and corridors of the homeowner take advantage of planting fruit trees. In addition, she added a portable awning. When there is heavy rain or heavy sun, she will pull the eaves to cover the trees. The house was completed in 2017, so far it is still like new and is used very carefully and cared by the owner. “I am a house addict, any corner must take care of me meticulously, clean it up”, she revealed. She mainly grows plants in pots, pots, but the fruit is always full of branches. The woman born in 1983 asserted that she did not have to embrace the dense planting of trees and green vegetables because she did not like the overcrowded house. Moreover, she wants to set aside space for the whole family to gather and open outdoor meals. She divided the tree into each section for convenient care. Fruit trees are preferred in sunny locations. The tree has tropical style (tropical), you can take care of it by spraying it periodically to avoid pests. Ornamental plants are planted in a cool, no-sun area and keep the humidity of at least 45-70%. With vines, most of Thuy Trang grow beef stem Philodondren (indoor plants), so it is imperative to live in a humid environment for air roots to develop. The garden has a variety of vegetation. In the past, she planted many flowers, especially roses. However, growing flowers is forced to spray many drugs to stimulate and spray regularly. In addition, the drug must be constantly changed because of hemorrhoids and drug hoppers. Therefore, she switched to planting trees. Fruit trees in the garden are quite plentiful including: Mango, pomelo, star fruit, whip, guava, orange, toad, sapoche, pomegranate … The entrance door has a large glass frame. Harvest the fruit. Reading corner, relax in the afternoon of the whole family. When commencing the renovation, she thinks that this is not only a place to live but also an environment worth living, for the children’s physical and thinking development. The owner grows a variety of fruit trees in the North. Trees help compensate for the freshness and alleviate the heat, the cramped and the hustle and bustle pace of the bustling city. The interior uses subtle dark tones on a white painted wall background. The rooms are linked together by open space.

Being passionate about plants and sticking to plant research, especially flowering plants, TS. Do Van Truong , Vietnam Museum of Nature, Vietnam Academy of Science and Technology, famous scientist for many discoveries for new species, dedicates his youth to focus on research in this field. TS. Do Van Truong on a field trip. Along with the professional work such as biodiversity research, plant resources … an important part of the TS’s indispensable work. Do Van Truong and colleagues to find and identify new species for science. And each new finding is published is a special story with lots of sweat and tears. TS. Do Van Truong recalled that in 2017, when he was on a field research trip in Kom Tum, he was on his way back to Nha Trang and happened to be surfing on Facebook and saw a young friend posting a picture of a tree wildly. See photo, TS. Do Van Truong saw that this was a very strange tree, never seen before. Immediately exceed 200 km to enter Binh Dinh area and approach strange trees. Arrived, TS. Do Van Truong received guidance from a local resident and confirmed that it only took half a day to both go and return. So at 10:00 a.m. the group set off with their inventory of a few loaves of bread for a makeshift lunch in the woods. As expected, about 2 hours later, we have reached the place where there are strange trees. The team was very happy and spent an hour observing, describing, recording, and collecting samples of strange plants to study. Due to the fact that indigenous people have a clear understanding of the terrain in the area, the group decided that when they returned, they would not return to the old road but approach another forest area to find a trail back to the village. However, the more you get lost. 5:00 pm, darkness collapses, only 2 small biscuits left, the phone has no waves, cold weather and small rain. The group decided to stop and approach the nearest mountain to hope for phone waves, because according to many years of experience in the jungle, TS. The more you know, the more you get lost and lose your energy. Hunger, cold, and even panic occasionally rekindled. 5am ​​the next morning, TS. Do Van Truong and his colleagues decided to go back to the old way. The group went continuously for 5 hours to reach a large stream flowing back to the village and met two communal militiamen who were on a mission to “find stray scientists”. As it turned out, during the night, many of the people in the village were unable to sleep because of their anxiety. The police, the military, even professional hunters were mobilized to find you. “It was a memorable trip in life. Hungry, thirsty, arriving in tattered clothes. Luckily, this strange tree was later researched and identified as genus (Michaelmoelleria F.Wen, YGWei & TVDo, gen. Nov.) And plant species (Michaelmoelleria vietnamensis F.Wen, ZBXin & TVDo, sp. nov.) new to world science ”Dr. Do Van Truong said Michaelmoelleria vietnamensis F.Wen, ZBXin & TVDo, sp. nov. The feeling of a winner TS. Do Van Truong added a memory, that is in 2018, during a trip to investigate and survey the flora of Vu Quang National Park (Ha Tinh), on the way back, colleagues discovered a tall vines. , beautiful flowers immediately take it and send it to you. At this time, TS. Do Van Truong is working in China, when he received the photo, he had a premonition that this was a very strange plant in his group. TS. Do Van Truong on a field trip When he returned home, he decided to find this vine. By the end of 2020, TS. Do Van cooperated with Vu Quang National Park to conduct a field trip to an area where strange plants were recorded before. This is a dangerous terrain and very far from the ranger station, so the group decided to sleep in the forest with determination to “hunt” with strange trees. At 6 am, the group will start their journey from the ranger station until 4pm to reach the desired area. However, within a radius of 1 km where colleagues used to take pictures, PhD. The red-eyed field still cannot see vines or regenerated seedlings of strange plants. TS. Truong commented that it is possible that individuals of strange plants have died due to the strong impact of previous droughts. At 5:30 it was dark, the group decided to camp, rest and drink wine for the sad: “Quiet space, darkness covered, and depressed mood. That feeling, I still remember until now ”, TS. Do Van Truong recalls. 7:30 the next morning, TS. Do Van Truong decided to search again, in the hope that the tree has flowers, that is to bear fruit, and is a source of seeds for regenerating seedlings. This is an area where the forest is not affected, definitely the trees are just around somewhere. He went back and forth many times, digging through the forest ropes, he finally found, it was a tree trunk lying hidden in a large cluster of trees. “At that time, she was sweaty and tired. But the feeling of victory is great ”. Up to now, on the basis of the results of analysis and research, PhD. The school has confirmed that this is a new plant species for world science, named: Aristolochia vuquangensis TVDo, sp.nov. Aristolochia vuquangensis TVDo, sp.nov. Fruit for efforts Hard, even dangerous, however, TS. Do Van Truong has received “sweet fruits”. In the period 2010-2020, PhD. Do Van Truong and colleagues have discovered and described 1 genus and 28 new species of higher plants for world science, of which 1 genus and 22 species were discovered and described in Vietnam. Also in the period from 2010-2020, PhD. Do Van Truong and colleagues have published a total of 26 scientific works describing new plant species in international journals. In which, 23 works were published in prestigious international magazines. According to TS. Do Van Truong, research to discover and describe new species for science, especially newly discovered species in Vietnam is of great significance. The first is to highlight the role and importance of biodiversity in Vietnam, which is a solid scientific basis for classification for conservation and application research. learning, probiotics …). In addition, scientists initially researched, propagated and successfully conserved a number of new species. This is an important basis to conduct research activities to develop precious plant genetic resources in Vietnam for the needs of use (medicinal herbs, ornamental plants, food for insects …), making an important contribution to the process. process of conservation and sustainable development of wild plant species. There are many concerns Being enthusiastic and pursuing plant research for many years, PhD. Do Van Truong said that he himself still has a lot of concerns. “Vietnam is a country with high biodiversity, but we do not have an in-depth research program on Vietnam’s flora. This is very unfortunate. We hope that there will be a unit with sufficient expertise and international relations to conduct a methodical and extensive research on the flora of Vietnam ”, PhD. Do Van Truong confided. One more concern of TS. Do Van Truong, that is attracting young people to participate in plant research. Part of the reason is that basic research is always a “silent” industry that has not been given adequate attention and investment. Moreover, the difficult life makes many young people who graduated from school are not eager to do research but turn to another direction. “If this situation continues, not knowing after 10-20 years, who will we marry to continue our work”.

Subconsciously, Chelsea Wood dreams of becoming an ocean biologist, studying the lives of dolphins or diving deep into the sea to solve the mystery of the vast animal world. She has a special fondness for sea snails, spending time watching each little animal slowly moving inside the mini “laboratory”, a wooden basket. It took more than 20 years, Chelsea Wood, then known in the world of marine biology at the University of Washington, realized that the childhood world in a snail shell as a child hides life from the larvae. The flatworm species Cryptocotyle lingua (a common fish parasite), in the naive thinking of a young age, looks extremely adorable and has the charm of two black-eyed dots. Wood couldn’t take his eyes off the bizarre creature, and then constantly questioned their origins, so much so that he said, “One day, I’ll know who they are.” Going to college, Wood spends most of his time in the lab with his … stupid friends. Wood’s biological world lives on its host, like an outcast in the animal universe. Apparently, the scientific community is indebted to Chelsea Wood (et al.), When the researcher initiated the movement to preserve the parasites has always been estranged by science. The microscopic, “parasitic” world must make up nearly half of all known animals on Earth, but not all species are harmful to the host, including humans. The parasites make up nearly half of all known animals on Earth. Imagine one day in the next century, 10% of parasites disappear due to climate change, there is no suitable host, what will happen? Wood is concerned, but we’re indifferent. The International Union for Conservation of Nature only lists a few species of mussels or lice parasites as “high risk”, while the parasite world is extremely large. Chelsea Wood said that, neglecting the parasite, is accepting failure in biological science research. Scientifically contested, critically opposed the views of anyone who supported Chealsea Wood. Biology preserves the fallacy, that we are taking slow steps … but surely to explore the parasite world, not forget. A few support Chelsea Wood, believing that the achievements in parasitic research open up potential for breakthroughs in medicine, ecology and the history of species development. The charm of the parasite lurks within the ancient genetic resources to evolve, from the tiny “super evil” crustacean ready to kill the fish’s tongue to the wasps with venom that paralyzes the brain of cockroaches. We still envision creatures swung, stained and frightened, but the parasitic world impresses in their own way, and holds a key part of all species’ lives. Many, but not all Humans are superior animals, but share the same fate with the vast majority of other species such as lions, zebras or even fish and shrimp. That is, we all become hosts of many parasitic groups, even though humans do not show hospitality to them. Science believes that hundreds of different parasitic species have evolved to adapt to the body, and then attach their lives, including many generations to come, to the human body. Chealsea Wood doubted, from the time she was sitting in the university lab, about the parasite’s ability to “grow like a mushroom” – a moment when she thought of herself as a nutritious buffet. energy for any hunger in the biological world. Big idea met together. When ecologist Skylar Hopkins (University of North Carolina) defined the concept of parasitism, Wood seemed to open his eyes. The nature of the parasite is an incompatible symbiotic relationship between species, in which one species is a parasite, one is a parasite, the other is a host or a host. Just imagine this simple: species of parasites are not wild “race arms” like hunting – being eaten, but the trick of choosing a “leisurely” life with a big partner. Wood, and then Hopkins, foresaw that nature doesn’t like emptiness, and if given the chance, something evolved to fill that void. This becomes the foundation for the two scientists to mobilize a wave of in-depth research on parasites towards preventing the endangered threat of many species. New England buffalo leech suddenly disappeared for the past 10 years. Life on Earth formed inside a mixed bowl of soup, with primitive drops of Coacervate, making up countless creatures. The parasite thus evolved, over billions of years, from a single-celled microorganism to today’s complex vertebral body. Amateurs will be shocked if they know that parasites exist everywhere, from parasitic fungi, parasitic worms, to parasitic birds, even demon bats with their favorite “food” being the blood of other animals. The oblivion of science made Hopkins speak, and like Wood at first, received only the shake of his head. The Wood-Kins couple did not give up, but quietly enlarged parasite conservation research groups in the US, then spread to Europe, starting to implement a global plan in early 2021 with the media front: Journal of Biological Conservation. Ten years of tracing parasitic science, underwater or on land, are frustrating days when Wood-Kins has only kept two “ancient” data samples from the 1940s. Death and death – the host dies, the parasite dies, without any recorded evidence. The endangered rare dwarf pig in the foothills of the Himalayas made Chelsea Wood and Skylar Hopkins discouraged to learn that this pig-like blood-sucking lice have hardly disappeared. And what makes Wood-Kins want to give up most is his ambition to eradicate a parasitic louse on the California Falcon, or the New England buffalo leech that has been suddenly missing for the past ten years. Normalization of relations One winter night in December 2020, Skylar Hopkins received a long email with concerns about the world of parasites. How terrible would that biological universe, if one day disappear, be? Hopkins quietly painted a pale picture: the parasite is not worrying, only afraid that the ecosystem will “explode” without the parasites. Some people consider the female parasite needs to adjust the population, limit the individual quantity of the species to keep the balance for the ecosystem. Some people assume that no parasite means that many species lose their food source. Hopkins believes this, because some parasites transform their hosts to evolve, manipulate the “mentality” of new owners, turning new hosts into good prey for other species. Hopkins called this a talent for hypnosis, she discovered in the horse mane worms (Nematomorpha) specialized in cricket parasites, thanks to the substance capable of destroying the nervous system that prompted the owner to voluntarily jump into the water and drown. The host dies, the horse maneworms will escape and begin a new cycle with the next victim, while the crickets become food for freshwater salmon. With Chelsea Wood, humans do not rush to a universe without parasites. In many countries like the United States, the disappearance of some intestinal parasites has caused many confusing autoimmune diseases. Thinking explains it in a way: the immune system evolved along with an “association” of parasites and protozoa, so losing this association begins to attack itself. That is why many people with Crohn’s disease (chronic trans-walled enteritis) have sought a cure when rebalancing the intestinal ecosystem with some parasitic species. Horse mane worms are capable of hypnosis, causing the cricket host to commit suicide. Obviously, the movement Wood-Kins initiated, which made even the hardest of people more or less happy. Dr. Bobbi Pritt, for example, famous at the Mayo Clinic for his “anti-parasitic” view, is always busy carrying blood tubes containing dozens of malaria parasites, looking closely at the diseased brain tissue. Toxoplasma curvature to nest, or cure ulcers from sandfly bites. Blog page “Poisonous, Crazy but Beautiful” was born, towards the medical point of view is to remove pathogenic parasites but need to dig deep into research and be ready to preserve when needed. It seems that Wood and Hopkins have successfully conveyed the message: we do not need to love parasites, but should “normalize” their relationship when there are many hidden parasitic mysteries to nature and species themselves. people. With mother of nature, understanding first and then knowing what the next step should be …

Office tree frog Rhacophorus vanbanicus in the wild. The Vietnam Academy of Science and Technology said that the Institute’s scientists, in collaboration with Russian and German scientists, have discovered and described three new species of tree frog in Lao Cai and Ha Giang. Based on analysis of morphology, molecular genetics and bio-sound, a team of researchers from the Vietnam Museum of Nature, Institute of Ecology and Biological Resources, under the Vietnam Academy of Science and Technology and Researchers from the Serbian Zoological Institute, Russian Academy of Sciences and the scientists of Cologne Zoo, Germany have discovered and described three new species of tree frogs including Rhacophorus vanbanicus, Zhangixalus franki and Zhangixalus jodiae. The table frog species Rhacophorus vanbanicus Kropachev, Orlov, Ninh, and Nguyen, 2019 Named after the standard sampling site in Van Ban district, Lao Cai province, Vietnam at an altitude of 900m, with evergreen forest habitat on high humidity rocky mountains with frequent fog and drizzle. The table frog frog features a brown back with two green stripes on the back from the back of the eye to the groin and forms a green triangle at the top, the underside of the thighs yellow-orange with 5-7 characteristic black nodules. This species is of medium size with an adult male body length of about 34.8 mm, head width less than head length. This finding is published in specialized journals Russian Journal of Herpetology. Zhangixalus jodiae in nature (A & B), and front and hind limbs (C & D). Goat tree frog species Zhangixalus jodiae Nguyen, Ninh, Orlov, Nguyen, and Ziegler, 2020 Named after Dr. Jodi Rowley – The Australian Museum for her outstanding contributions to the study of amphibian classification in Asia. This species was found in Quan Ba ​​district, Ha Giang province. In terms of morphology, the new species has an average body length in the range of 36.1-39.8 mm, the width and length of the head are equivalent, the tip of the snout is round, with the teeth of the cane leaves; front and hind limbs have swimming membranes; blotchy green back, cream-colored armpits with large black spots, groin and anterior-posterior part of thigh with alternating black and orange spots. Genetically, the new species is on the same branch as Z. nigropunctautus, Z. yaoshanensis, Z. pinglongensis and Z. chenfui. Z. jodiae had the closest genetic distance to Z. pinglongensis was 3.57%. Biological tones were recorded at 17.3-20.9 degrees Celsius with each vocal lasting 1.1 seconds and consisted of six notes, each note about 6 milliseconds, the distance between two notes about 15 milliseconds. . The dominant frequency is 2.0kHz. The notes of a voice have variable amplitude, with the last note having the smallest amplitude relative to the other notes. The discovery of this new species of frog was published in the journal Journal of Natural History. Standard specimen of Zhangixalus franki (A & B) and a drawing of anterior and posterior swimming membrane (C). Species Frank tree frog – Zhangixalus franki Ninh, Nguyen, Orlov, Nguyen, and Ziegler, 2020 named after the late German professor, doctor, veterinarian and amphibian conservationist Frank Mutschmann in honor and recognition of his support in amphibian research and conservation projects. residing in Vietnam. The new species can be distinguished from other species in the Zhangixalus genus based on a combination of the following characteristics: large body (from 77.9-85.8 mm in males), a blue dorsal surface with spots small dark brown, with white stripes separating the upper face and lower face of the body, developed parotid glands. This species was found at an altitude of 1,300 m in Quan Ba ​​district, Ha Giang province. The typical habitat is tropical evergreen forest on the mountains. Genetically, the new species in the same branch is most closely related to the Z. duboisi species, the genetic distance between the two species is about 2.51%. Findings about this species were published in the journal European Journal of Taxonomy.

However, progress in military science has not stopped, in order to reduce the casualties to soldiers on the battlefield, some countries are experimenting with new forms of combat with the creation and use of systems. automatic robot. In terms of strength, they have the ability to replace a mechanized company. Russia is also not lagging behind the general trend. At present, Russia owns a number of robot combinations of different classes: Platform-M and Nerekhta weigh only 1 ton, Companion weighs 7 tons and finally heavy vehicles remotely controlled. 15 tons of Vikhr, built on the basis of the BMP-3 infantry fighting vehicle. Field tests have shown that the most successful option is the Uran midsize robot program, which aims to shape the appearance of a versatile and inexpensive multi-functional platform that can be easily modified for create final dedicated versions on that basis. Unfortunately, during the mission deployment in Syria, the Uran-9 robot and the Uran-6 revealed many shortcomings, leading to the need for corrections. Until 2019, the only real result of the program was that the Uran-6 remote bomb clearance vehicle was received by the Russian engineer force. The Uran-9 combat robot begins to return to the active part of the Russian Army Then came the modernized Uran-9 infantry escort robot platform, the first version of which was briefly tested in Syria. Today this combat vehicle is equipped with a 30 mm automatic cannon, 4 Ataka anti-tank missiles and six Shmel-M thermo-missile launchers. The Uran-9 robot complex is capable of destroying any armored vehicle at a distance of up to 5 km, as well as handling reconnaissance missions, suppressing enemy laser navigation systems and smoke curtain settings. The Russian army has begun to set up an experienced unit equipped with the aforementioned robot complex. According to the current plan, after the completion of the production of the order and the training of the operator, the handover of the Uran-9 to the combat units will begin. After the above process, it is likely that the Uran-9 robot will return to the Syrian battlefield to re-evaluate the shortcomings that caused it to be “disgraced” that has been completely overcome or not.

Bright Side brings together 10 rare creatures that are on the brink of extinction. Global mountain gorilla Currently the mountain gorilla has increased to about 1,063. They can only be found in protected forests. This is evidence that conservation efforts can bring a species back on the brink of extinction. However, illegal human hunting remains a major threat to the fauna of Bwindi-Sarambwe. Sao la The saola species was discovered in the Annamite forests of Vietnam. The main threat to saola is hunting activities and environmental climate impacts. That is why many conservation organizations have collaborated to create a safe environment for them in nature. Animal with dunnart bag This tiny creature can only be found on Australia’s Kangaroo Island, with an estimated population of less than 500. The widespread cleaning of the vegetation by humans has put the dunnart in a very dangerous situation. In addition, wildfires in Australia in 2019 and 2020 have burned 95% of the species. That is why a closed sanctuary was created to keep dunnart and other endangered species safe. Iberian lynx This rare species can only be found in the jungles of southwest Spain. From 1985 to 2001, their population decreased by 87%; So far, there are about 400 lynx in the wild. Their natural habitat continues to be destroyed by new highways and cut down trees. Black-footed ferret While people thought they were extinct, tiny creatures have proven to still exist. However, their population is rapidly declining due to disease and the loss of their natural habitat. Their total population is estimated at around 370 in the wild. Massive restoration efforts by many federal agencies and zoos have provided space for the weasels to survive. Gharial crocodile In 2010, only 15 crocodiles were found in the Gandak River in Bihar. That’s why in 2014, a conservation initiative freed 30 crocodiles from captivity and returned them to the river, and their population began to increase. Kakapo For the first time in 70 years, the kakapo population is increasing with about 213 species of birds existing. Only during the 2018-2019 breeding season, 71 young survived, which is a record number for this species. The recovery team tries to make sure the birds stay healthy and protected from infection. Their next goal is to find a good habitat for the birds as disease is their main threat. Canadian harbor seals Found in Quebec, this is the only species of its kind that can only survive in fresh water thanks to fish. To date, only more than 100 live in the area. The cause can be attributed to human hunting. Also, in many cases, seals get trapped in their gears and cannot free themselves. Leopard Amur This leopard has found a way to survive in the jungle in the Russian Far East. They live up to 15 years in the wild and more than 20 years in captivity. They have an amazing ability to run very fast and jump high. However, the loss of habitat and human activity has reduced their number to about 84 individuals. Vaquita dolphin This very rare marine mammal was discovered only in 1958. However, in recent years, vaquitas dolphins have been victims of illegal fishing activities. They are often trapped in fishing nets. That is why their population is only about 10 in the Gulf of Mexico. They can be found in shallow water but will quickly swim away if a boat approaches them.

At first, his orchid garden only had a few baskets, with a value from a few hundred thousand to several million. Each orchid is carefully selected and cared for by him. Because he does not have much experience in caring for orchids, Mr. Hai chooses easy-to-raise and easy-to-grow sausages to accumulate more experience. In the process, he also encountered many difficulties, having orchid rolls because he did not know how to care but was waterlogged, the tree has not grown yet. The family also advised him to leave, because orchids are difficult to raise, with high prices, to maintain his passion is not easy. However, his love for this flower has helped Duy Trong Hai overcome difficulties, he looks to people who have experience in the profession to learn, interact with his brothers in the flower love association and gradually find a way to raise orchids. healthy. The joy of successfully cultivating an orchid manually made Duy Trong Hai forget her previous hardships and more determined to pursue her passion. Up to the modern time, the orchid garden of Duy Trong Hai owner has collected many different strains of orchids such as: Orchids, 5 CT SH, 5 CT HD, 5 CT Thao Nguyen, Anonymous Beauty, Hong Phu Hoa, Hong Runner …. Each spring roll has its own beauty. There are pure sausages with flowers and brood leaves, others blooming in brilliantly beautiful bunches. Hundreds of colorful racing flowers adorn the garden of the young boss. Mr. Duy Trong Hai specially dedicated a large garden to grow orchids, the distance between the rolls is also carefully calculated by him so that the orchid grows well, not crowded or lack of light. When a guest comes to visit Mr. Hai’s house, he will wholeheartedly introduce clues to buy beautiful orchids and how to choose like orchid rolls. These are the experiences that he gathered after years of playing orchids and growing orchids. He advised orchid players not to buy trees with thin, short, broken roots. Most orchids in your garden have a healthy root system, this is the first factor to help orchids grow and live well. Sharing more about the meaning of each orchid in the garden, Mr. Duy Trong Hai happily said “There are rolls, I have to go to the forest, it takes a few days to bring back. But when I arrived, I found the orchid so beautiful, I was fascinated by the look, so I did not feel tired. When there are friends to “hunt” beautiful orchids, he offered to go along. Just one person confided in his passion and found a satisfactory orchid “. For Duy Trong Hai, he is always lucky because his relatives and family understand and support him to pursue the joy of growing orchids. At first, seeing that he spent a lot of money in pursuit of fun, his family was a bit afraid, but gradually found this joy more rewarding and made him happier, loving and caring for his family, so the whole family. no more objections. Mr. Hai confided, “Playing orchids is not just a hobby but also helps me to change myself.” When planting orchids, he learned to be patient, to care and to listen. When he talked to people with similar interests, he learned to inspire and become more sociable. Many people believe that playing orchids is burning money, not realistic, but when you have real love, you can feel the joy and values ​​that orchids bring. He believes that everyone has their own joy, just boldly pursue your passion, not too interested in social prejudices.

According to the feng-shui concept, orchids will neutralize killing gas, bring spiritual aura, good things into the house and repel bad luck. With strong vitality, the ability to attract positive energies, a house of moth orchid is a symbol of luck, prosperity and brings wealth and fortune to the homeowner. Because of this meaning, businesses, business people, many households always choose to display orchids on holidays, Tet, and inauguration. Orchids are chosen by many people to display Tet. Increasingly, moth orchids are grown more popularly, with many beautiful and sharp colors; Proper watering can be played for one to several months, the price is not too expensive; suitable for many spaces … Therefore, over the past time, moth orchid has been favored by many families. Before the spring of Tan Suu in 2021, the market of moth orchid was quite exciting. “This year’s Tet market, people play the demand for moth orchids is very high. Garden houses are sold out every year near the end of the year, but so far they have sold almost all their gardens. Last year, the gardeners had 45,000 trees, this year increased production to nearly 80,000 trees, consumption faster than last year. The color of flowers, this is very richer than the garden color concentrating more than 20 colors such as yellow, red, purple, pink … ”- Mr. Ngo Minh Truong, owner of orchid garden in Thanh Oai district, Hanoi said. According to the home gardeners, this year due to the influence of the Covid-19 epidemic, the import of moth orchids from China is facing many difficulties, so the flower products are consumed faster than every year. The orchid pots with all kinds, colors and sizes are displayed for sale with an average price of a scallop orchid, priced from 250,000 to 300,000 VND / branch. Smallest flower pots with 3 branches cost 900,000 VND, small pots average 2-3 million VND, large size up to hundreds of million VND … Orchids are grown at home gardens in the direction of high technology. 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. . Mr. Nguyen Ngoc Khoa, a resident of Ha Dong district, shared that last year, his family also displayed a pot of moth orchids, just once a day of watering, it could be played nearly 2 months. Displaying orchid pots makes the living room more bright and luxurious. For that reason, this year, his family continued to choose to buy moth orchids to play Tet: “The indoor display is very beautiful and graceful, I have come to the garden houses to book in advance. a month to choose beautiful orchid pots, like “. 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 in Tet holiday.

Four newly announced plant species originate from Bidoup – Nui Ba National Park. On the morning of April 18, the Director of Bidoup National Park – Nui Ba, Dr. Le Van Huong informed, three famous international journals specializing in botanicals, including Brittonia, International Camellia Society and Phytotaxa, have just announced four species. New plants for science come from this national park. Of which, two species belong to the genus Tra my (Camellia) and two species belong to the genus Thu Hai Duong (Begonia). According to Dr. Le Van Huong, the new findings are published in prestigious international journals specialized in botanical science, which is the pride of the scientific staff working in Bidoup – Nui Ba National Park (Lam Copper) and associates. According to the announcement, the genus Tra my (Camellia) is the largest genus of the Tea family (Theaceae), with more than 300 species recorded globally. Vietnam and China are the two countries recording the most distribution of species of this genus. In recent years, there have been many new discoveries and announcements of species of this genus, which have significantly added to the national and regional biodiversity. Tea my Bidoup – Camellia bidoupensis (Source: National Park Bidoup-Nui Ba). Two new Tra my species were discovered and announced in the first months of 2021, at Bidoup – Nui Ba National Park, including tiny camellia (Camellia flosculora Curry, VS Le, CQ Truong & VD Luong, sp.nov. ) and Tra my Bidoup (Camellia bidoupensis Truong, Luong & Tran, sp.nov.). Tiny flower tea was first sampled in the dwarf forest on the mountain top in the area of ​​Hon Giao, Bidoup National Park – Nui Ba. This is a small to medium, evergreen tree, 3 to 8 meters high, with oblong and hairy, lanceolate leaves. The tree blooms in September – October, is white, with flower sizes from 0.5 to 0.7cm, this is Tra My with the smallest flower size in the world recorded up to the present time. Little flower tea – Camellia flosculora (Source: Bidoup-Nui Ba National Park). Tea my Bidoup is a small to medium tree, evergreen, from 3 to 7 meters high, the bark is gray-brown. The leaves are round or elliptical wide, 8 to 12cm long, 3.5 to 5.5cm wide, and thick. The tree flowers also in September – October, the flowers are white with chicken fat, 2 to 2.5 cm in diameter. This species is named after this species distribution site Bidoupensis, as an affirmation of the authors of its origin. In Vietnam, the genus Tra my has been studied for a long time by typical authors such as: Assoc.Prof. Dr. Tran Ninh, Hanoi National University; Dr. Luong Van Dung, University of Da Lat; Dr. Luu Hong Truong, Institute of Ecology in the South … increase the total number of species of this genus to more than 80 species, by 2021. With Begonia, there are more than 90 species recorded in Vietnam, many species have narrow distribution and endemic. Two species of the begonias recently announced at Bidoup – Nui Ba National Park, Hon Giao (Begonia hongiaoensis CWLin, TCHsu & Luu, sp.nov.) Are named after a mountain mass of biodiversity. Very high in Bidoup National Park – Nui Ba and Thu Hai Duong Dong Road (Begonia lamdongiana CWLin, TCHsu & Luu, sp. nov.). This species is also named after its origin in Lam Dong province, where the species was first discovered and sampled. “The above two species of begonia are the result of the cooperative project” Plant Survey in Langbiang Plateau, Vietnam “between the Botanical Conservation Center Dr. Cecilia Koo (Taiwan), Southern Institute of Ecology. and Bidoup – Nui Ba National Park ”, information Dr. Le Van Huong. Hon Giao – Begonia hongiaoensis (Source: Bidoup-Nui Ba National Park). Hon Giao begonia is a herbaceous plant, 20-30 cm high, leaves are not lobed, not symmetrical, oblong egg-shaped to wide egg, long petiole. Plants flower in January to March every year, white to pale pink petals, yellow stamens merge at the base of the flower. Lam Dong begonia is also a herbaceous plant, 10 cm tall, with many feathers. Fruit hard, light green to cream pink, triangular, 5 to 10 mm long, 4 to 8 mm wide. Leaves and petioles are small, light green to dark pink, 8.5 – 25 cm long, 2.2 – 3.5 mm thick, the leaf blade is asymmetrical, ovoid to lanceolate, 10 – 13 long, 5 cm, 5.5 – 7.5 cm wide, heart-shaped leaf base is clearer than Hon Giao, the underside of leaves is silver with many feathers. Flowers are simple, stalks 12 – 23 mm long, white to pink, blooming in September to November every year. Begonia lamdongiana (Source: Phytotaxa Magazine). The director of Bidoup National Park – Nui Ba, Dr. Le Van Huong said that to be announced a new plant species for science must undergo a rigorous and independent evaluation process by international scientists specializing in In-depth subjects on species, subspecies are close to newly discovered species. From the initial research ideas, determine the survey area, collect, dissect, find the differences, compare with hundreds of domestic and foreign samples and documents, synthesize the results and send to the journals. industry journalism, answering the questions of the independent reviewer. Expanding collaborative research and strengthening field surveys to fully assess the population level and conservation status of plants, focusing on rare species, narrow natural distribution area is a Jobs are essential in biodiversity conservation in Bidoup – Nui Ba National Park. This information is the foundation for developing a conservation strategy, planning and plan suitable for each species or species group on the basis of existing resources. The announcement of four new species for science, originating from Bidoup – Nui Ba National Park, once again affirms the very special biodiversity values ​​in this area.

Coffee stenophylla is said to have a great taste. Photo: RBG KEW. In the dense rainforest of Sierra Leone, scientists have rediscovered a species of coffee that has disappeared in the wild for decades. This is a plant that can help ensure the future of coffee, which is already affected by climate change. In 2050, climate change halves coffee production On April 19, researchers said, this coffee tree has a name Coffea stenophylla , is able to withstand higher temperatures than Arabica coffee accounts for 56% and Robusta coffee accounts for 43% of global production. Stenophylla has been shown to have a premium taste, similar to Arabica. Botanist Aaron Davis, who leads research on the anti-climate change stenophylla coffee. Photo: Inews. Botanist Aaron Davis, who led the study published in the journal Nature Plants , said, before disappearing, stenophylla plants were grown in regions of West Africa and exported to Europe until the early 20th century. According to Mr. Davis, the stenophylla coffee tree has not been seen in the wild in Sierra Leone since 1954 and in the Ivory Coast since the 1980s. This is given as an evidence. Climate change is a pressing concern for the billion-dollar coffee industry. Many coffee farmers around the world are experiencing the negative effects of this phenomenon. The taste of Arabica is considered excellent and offers a higher price than robusta, which is mainly used for instant and blended coffee. But Arabica has a limited tolerance to climate change, and research has shown that global production of this coffee can drop by at least 50% by mid-century. The fruit of the stenophylla tree is dark black. Photo: Reuters. Unlike the red and sometimes yellow berries of Arabica and robusta, the stenophylla fruit is dark black. The coffee beans are inside the fruit. The stenophylla coffee grows at an average annual temperature of 24.9 ° C, 1.9 ° C higher than Robusta and up to 6.8 ° C higher than that, the researchers said. arabica coffee. Rediscovered stenophylla “proves the future” of the coffee industry Dr Davis said the rediscovery of stenophylla could help “prove the future” of the coffee industry, to support the economies of some tropical countries and provide livelihoods for more than 100 million farmers. people. Stenophylla can be used with minimal domestication, as a high value coffee for farmers in warmer climates. “In the long run, stenophylla provides us with an important resource for breeding a new generation of climate resistant coffee, as it has great taste and good heat resistance. “If historical reports on coffee leaf rust resistance and drought tolerance are believed to be correct, this will be a useful asset for coffee plant breeding”, Mr. Davis added. This study also included the evaluation of 18 coffee tasters on the taste of stenophylla species. A small sample of this coffee bean has been roasted and made into coffee, then enjoyed by a group of coffee connoisseurs. The report showed that more than 80% of the judges were unable to distinguish the difference between Stenophylla and Arabica when tasted. Accordingly, this species has a complex flavor, with a natural sweetness, high average acidity, and a fruity taste when sipping in the mouth. The rediscovered stenophylla grows wild in Sierra Leone. Photo: RBG KEW. From December 2018, Dr. Davis and study co-author Jeremy Haggar of the University of Greenwich and coffee developer Daniel Sarmu searched wild stenophylla in Sierra Leone, where it is historically grown as a coffee tree about a century ago. Initially, they discovered a single tree in central Sierra Leone. They then discovered a healthy population of wild stenophylla some 140 kilometers southeast of Sierra Leone. “Both sites are tropical rainforest, but stenophylla tends to appear on drier, more open areas: ridges, slopes, and rocky areas,” said Dr. Davis. According to Davis, stenophylla is threatened with extinction amid massive deforestation in three countries where it is growing wild: Sierra Leone, Guinea and Ivory Coast. “I think we are extremely optimistic about the future,” said Jeremy Torz, co-founder of the Union Hand-Roasted Coffee special coffee business in East London, which hosts the tasting of the coffee. stenophylla can deliver ”. Dr. Davis hopes one day that stenophylla will be re-grown in Sierra Leone on a large scale. “I think within five to seven years we will see stenophylla enter the market as a niche, high-value coffee, and then I think it will be more popular,” he said.

The new coffee variety Coffea Stenophylla has been forgotten for decades and has just been rediscovered. Photo: Reuters. In the dense rainforests of Sierra Leone, scientists have rediscovered a new species of coffee that has not been seen in the wild for decades – a species they think could help secure the future. of valuable items but are being affected by climate change. On April 19, researchers announced that the new coffee species, Coffea stenophylla, was more resistant to temperatures than Arabica (56% of global production) and Robusta (43%). ). Stenophylla has been shown to taste superb, they added, to be similar to Arabica. Botanist Aaron Davis, who led the study, was published in the journal Nature Plants According to the report, the new species of coffee Stenophylla was grown in parts of West Africa and exported to Europe until the early 20th century, and then abandoned after Robusta coffee was popularized. Many farmers around the world coffee belt are experiencing the negative effects of climate change – a pressing concern for a multibillion-dollar industry. The taste of Arabica coffee is considered excellent and offers a higher price than Robusta, which is mainly used for the production of instant and blended coffee. But Arabica coffee is less resistant to climate change. Research has shown that its global output could decline by at least 50% by the middle of this century. Stenophylla grows at an average annual temperature of 24.9 degrees C – 1.9 degrees C higher than Robusta and up to 6.8 degrees C higher than Arabica, the researchers said. . The rediscovery of Stenophylla coffee could help in the “future proof” of the coffee industry that supports the economies of some tropical countries and provides livelihoods for more than 100 million farmers, Mr. Davis – coffee research team leader at the Royal Botanic Gardens, Kew – said. “The idea is that Stenophylla can be used with minimal domestication, as a high value coffee for farmers in warmer climates,” he said. Stenophylla coffee provided us with an important resource for breeding a new generation of climate-resistant coffee trees, as it has excellent taste and high heat resistance. “If historical reports on the coffee’s resistance to rust (a fungus that ravaged coffee trees in Central and South America – PV) and the coffee plant’s drought tolerance is correct, then it is.” This means that it becomes even more useful to propagate the coffee plant, “Davis added. The study included taste assessments with 18 coffee tasters. Stenophylla has been found to have a complex flavor, with a natural sweetness, a medium high acidity, and a fruity taste when felt in the mouth. In December 2018, Davis and study co-author Jeremy Haggar of the University of Greenwich and coffee developer Daniel Sarmu looked for Stenophylla in nature. Initially, they discovered a single tree in central Sierra Leone. About 140 km (87 miles) southeast of Sierra Leone, they found a healthy population of Stenophylla. “Both sites are rainforest, but Stenophylla tends to appear on drier, more open areas: ridges, steep slopes and rocky areas,” Davis claims. Stenophylla has not been seen in the wild in Sierra Leone since 1954 and anywhere since the 1980s in Ivory Coast, he added. Stenophylla is threatened with extinction amid massive deforestation in three countries where it is known to grow wild: Sierra Leone, Guinea and Ivory Coast, the study’s new study author wrote. Unlike the red and sometimes yellow fruit of Arabica and Robusta, the fruit of the Stenophylla tree is dark black. The coffee beans are inside the fruit. Jeremy Torz, co-founder of Union Hand-Ro Rang Coffee special coffee business in East London, where part of the flavor test took place, said: “I think we are extremely optimistic about the future Stenophylla can bring “.

The venom helps the snakes defend themselves and hunts. Explaining the venom in the snake The research was carried out by experts at the Okinawa Institute of Science and Technology (Japan) with the Australian National University (Australia) and published in the scientific journal Proceedings of the National Academy of Sciences (PNAS). . Research indicates a link between mammalian salivary glands and snake venom glands. Agneesh Barua, lead author of the paper and a graduate student in evolutionary genetics at the Okinawa Institute of Science and Technology, Japan, said: “In the past, we had the basic foundations. to find out about this. “Now, thanks to evolution, we can dig deeper and more accurately into the relationship between mammalian salivary glands and snake venom glands.” Previously, scientists believed that the venom gland evolved from the salivary gland because the venom is composed of proteins that are transformed from saliva. The oral venom system is assumed to evolve through evolution, but how it evolved and the molecular structure in the venom system remains unknown. Research by the Okinawa Institute of Science and Technology and the Australian National University are the first scientific evidence to find an answer to this fake snow. To produce toxins, snakes have evolved in the direction of converting many different substances in the body into venom. Initially, scientists suspected the gene was behind the poison formation in snake venom and a number of different species such as spiders and coolie – the only primate to have venom. However, the study did not find out what causes the venom to develop in the mouths of the animals. The research does not focus on toxins because they grow quickly, they are complex mixtures of many compounds, the Baride scientist explains. From there, the scientists decided to switch not to check the genes that produce the toxin, but to study the genes that help change the salivary system into the venom gland in the mouth. These are genes that are involved in the venom but are not responsible for the toxin production. Contact toxins in the human body Human saliva contains toxins that produce toxins. Through testing the genome of Taiwan habu snake, the researchers found the gene that supports the change, named “metavenom network”. This gene is responsible for protecting cells from the stress caused by the production of large amounts of protein. Similar genes are found in the salivary glands of some mammals such as chimpanzees, mice, even humans or terrestrial egg-laying animals such as birds and reptiles. These two genes have quite similar modes of action. Both produce large amounts of protein in saliva. With snakes, this gene helps to create large toxic saliva, suitable for their hunting and defense purposes. While in mammals such as humans, genes also make large amounts of protein in saliva but does not contain toxins. The common thing that these genes have in common is their ability to produce toxins, but snakes combine many different toxins, while mammals produce simpler venom, which has a similarity with saliva, Baride says. In fact, under certain environmental conditions, rats can make many toxic proteins in their saliva. Or in human saliva contains Kallikrein, an enzyme that helps digest proteins and they are also components in the “metavenom network”. If mutated, Kallikrein will convert saliva into venom that causes pain and death for infected objects. If so, according to evolution, in the next ten thousand years rats may have venom in their mouths, and so can humans. Mechanism of venom production However, Barua said, Kallikreins in human saliva can hardly evolve into toxins in snake venom. The “metavenom web” is a method of defense or elimination of prey and it evolves according to the animal’s way of life. The same species of snake, but living in different terrains and environments, the toxin is also different. For example, snakes live in the desert, mainly hunt rats on flat terrain, their venom slowly seeps into their prey. But snakes that live in the rocky mountains have a stronger toxin, instantly killing the lizard-like agility. Meanwhile, humans have invented tools, weapons and social structures to increase labor productivity and to process food, so there is no need to use venom. In addition, the creation of the venom is difficult. If not used regularly, the venom is lost. For example, sea snakes used to possess venom but are now harmless because they switch from eating fish to eating fish eggs, which do not require the use of toxins. New research may not raise hope for human “superpowers” but scientists have found a way for species to control venom in the body, which may be the key of medicine. . Find out how genes that control external protein expression can recognize diseases like cancer. Because most deaths from cancer are due to cancer cells growing out of control.

Ho Tay embankment, section passing Quang Khanh street, is used by people to grow clean vegetables. Every day, Ms. Nguyen Thi Hoa, a native of Vinh Phuc (a housekeeper for a family on Quang Khanh street) regularly 2 times to water and care for the vegetable garden in the morning and afternoon. The vegetable garden here is very convenient for watering because it is close to the edge of the lake. The soil is poured into concrete holes like the rock-hole cultivation of the Ha Giang people. The guard of a villa on Quang Khanh street also takes advantage of his free time to grow vegetables to improve daily meals. There are all kinds of vegetables such as amaranth, water spinach, spinach, basil, cabbage … depending on the season. Ms. Hoa said that in order to have land to grow vegetables, she had to buy 5,000 VND / bucket, then put it in each concrete hole. Planting right on the edge of the lake, vegetables are always green because water is always enough. Without using plant protection drugs, vegetables here are only fertilized with microbiological fertilizers, so every day, Ms. Hoa has to pull grass by herself and catch worms. Harvest time depends on the growth rate of each vegetable. Water spinach will be harvested after about 1 month from sowing, amaranth after 2 weeks, vegetables usually just over 1 week are already picked … Taking advantage of about 100 meters of the embankment to grow vegetables, Ms. Hoa has enough vegetables for herself and her host family. Sometimes the vegetables grow too fast, she even has to give. Unlike vegetable gardens grown in the style of cultivation on Ha Giang rocky plateau, vegetable gardens on the bank of West Lake embankment, passing Tu Hoa street, are divided into beds like normal vegetable gardens.

According to the Sohu , the only snake species recorded in China is the coral snake (scientific name: Bungarus multicinctus). This species can kill people with venom less than 1 milligram, even the king cobra when confronted with them also have to “turn off the power”. Small body Coral snakes live in southern China, they mainly live near the water’s surface and eat fish, frogs, snakes, and rats. The average body length of an adult coral snake is from 1m to 1.8m. In appearance, the coral snake has a simple black and white color, the back has hexagonal scales, the alternating black and white rings stretching throughout the body, the black part is longer and more than the white. Unlike conventional snakes with a triangular head, the coral snake’s head is oval in shape and small. Coral snakes possess an easily recognizable appearance. Photo: Sohu Although coral snakes are venomous snakes, they are very shy and often active at night. They will run away quickly when disturbed, or hide their heads under their bodies if they feel bothered. Unless intimidated, coral snakes will not actively attack people. In addition, the two fangs of coral snakes are relatively small, the other teeth are not pointed, so they cannot bite through the human skin too deeply. Therefore, when a person is bitten, the pain will be relatively mild, even some people cannot feel it. But if the anti-poison serum is not injected in time, the person who is bitten will definitely not be cured. The venom is deadly To measure the toxicity of snake venom, LD50 (a lethal dose of 50%, a dose required to kill half of the individuals used as an experiment over a given experimental period) is used as a parameter indicator. Projection for toxicity measurement. According to the experimental data of coral snake venom, LD50 of coral snake venom to mice is 0.09-0.108 mg / kg (subcutaneous injection), 0.113 mg / kg (intravenous injection) and 0.08 mg / kg (intraperitoneal injection). LD50 of the mountain wind snake has a famous large venom at about 0.35mg / kg, but only equivalent to a quarter of the toxicity of coral snakes. Therefore, after comparing the LD50 values ​​of the known poisonous snakes, it was concluded that the coral snakes are the most poisonous snakes in China as well as in Asia, in addition they are ranked 8th on the rankings. rank of poisonous snakes in the world. This is the most poisonous snake species in China as well as in Asia, in addition, they are ranked 8th on the ranking of poisonous snakes in the world. Photo: Sohu In the early stage of being bitten by a coral snake, the small molecular weight α neurotoxin first binds to acetylcholine receptors at the neuromuscular junctions, preventing the transmission of neurotransmitters, causing Injured person shows drowsiness, body stiffness, drooling, muscle spasm and other reactions, the nerve mass at this time is reversible. Several hours later, a large amount of β-neurotoxin acts directly on the motor nerve’s pre-synaptic membrane, inhibiting the release of acetylcholine, causing skeletal muscle to lose its function of contracting and transform into constant paralysis, eventually leading to to respiratory failure. This process happened very quickly and violently. What to do if bitten by a coral snake? First, what needs to be explained here is that it is completely wrong to suck venom by mouth like in a drama, then the poison will go straight through the mouth and take the life of the smoker. Therefore, the best way is to take a picture of that snake or bring it to the hospital for identification and injection of anti-venom serum as soon as possible. Although the coral snakebite is not as deep as other species, when the toxicity develops, the patient will suffer extremely severe pain with death always imminent. Photo: Medihub If you have been bitten by a coral snake in the wild and cannot get help, you can burn the wound with fire. Theoretically, proteins and enzyme peptides (the main ingredient in coral snake venom) are inactivated in the presence of acids, alkalis, electrolytes and high temperatures. The main reason is that the coral snakes have short fangs and small amount of venom that can only bite into the shallow layers of the skin. Therefore, in an emergency, burn the wound skin into blisters. However, this method only works miraculously for the wound from coral snakes, not suitable for other poisonous snakes. In fact, poisonous snakes are not as scary as we often think. Except for the king cobra, most poisonous snakes are afraid of humans. So when you see snakes, take the initiative to stay away from them at least a stride, do not blindly raise snakes if you do not have the knowledge to avoid “drawing on the body”.

Mosquitoes transmit diseases such as chikungunya, dengue fever and zika. (Source: wwmedgroup) These mosquito carriers, species rodent animals Destroying crops, wood boring insects, and even domestic cats are invasive species that are causing enormous harm to humans and the natural environment. According to a study published March 31 in the journal Nature, researchers working at the Laboratory of Ecology, Taxonomy and Evolution at the University of Paris-Sacla in France estimate invasive species. the so-called damaging alien species has cost the global economy nearly $ 1,300 since 1970, averaging $ 26.8 billion a year. The actual number could be even higher, researchers warn. The team synthesized a wide range of harms that invasive species cause to different habitats, including plants, insects, reptiles, birds, fish, mollusks, microorganisms or animals. mammal. Most harm is related to ecosystems, crops, fisheries and disease control measures. The team has made a preliminary list of the top 10 invasive pests, including the plant-eating rats and the Asian gypsy moth – two species that are devastating crops across the Northern Hemisphere. The list also includes zebra mosquitoes native to Southeast Asia that transmit diseases such as chikungunya, dengue fever and Zika. According to the researchers, the average annual damage caused by invasive species triples every decade. However, there is some evidence that the number of invasive species has increased “exponentially” due to increasing international trade, as humans import many species of organisms. In Australia, wild rabbit populations of European origin, first recorded in the early 19th century, have become invasive species causing great harm to the ecology of the Oceania nation. this over the past 150 years. They reproduce at an uncontrollable rate, consume soil, damage native species, as well as destroy crops with billions of dollars in damage. On the island of Guam, US overseas territories in the Pacific, invasive brown tree snakes native to Australia and Indonesia have “slaughtered” the majority of native bird and lizard populations since being accidentally brought in to come here in the mid-20th century. They also threaten people and sneak into equipment, causing frequent power outages. In forests in the US and more recently Europe, the longhorn beetle originating from Asia is also destroying the vegetation, causing serious damage to the ecosystem. According to the study, domestic cats are also among the top 10 invasive pests. This animal that has been “traveling” around the world for hundreds of years has now become an “invasive” species on most islands in the world, “slaughtering” birds, reptiles and animals. Amphibians in many parts of the world. The United Nations Scientific Advisory Committee on Biodiversity (IPBES) said that it is among the top 5 culprits of environmental destruction worldwide, along with changes in land use and resource exploitation. , pollution and climate change. In 2019, IPBES estimates that the number of invasive species has increased to 70% since 1970 in the 21 countries studied. Laboratory director on Franck Courchamp said international trade will increase more species of organisms introduced, while climate change will help more of these imported species survive and thrive. With the above research, scientists hope that by giving a figure of the damage caused by invasive species, people as well as authorities will raise awareness about the severity. of invasive species. Early detection, good data combined with preventive measures can significantly reduce the damage invasive species cause. The researchers also hope this issue will be included in the list of the serious environmental challenges facing humanity to receive more attention.

Towards the end of this century, organisms living on the ocean floor faced increasing dangers from ocean warming. (Photo: thiennhien.net) According to climate warming projections, the number of species has decreased in the equator and increased in the subtropics since the 1950s. This is the general state of all 48,661 species and they are divided into sub-species. seabed (benthic) and in open water (floating fish area), fish, molluscs and crustaceans. Results from a study led by the University of Auckland (New Zealand) show that open water marine species in the Northern Hemisphere tend to move more towards the North Pole than benthic species. Meanwhile, species in the southern hemisphere do not have a similar wave of movement. The reason is that the warming ocean in the Northern Hemisphere is more pronounced than the Southern Hemisphere. In the past, the tropics were always considered to be stable and have an ideal temperature for reproduction because so many species of organisms appear there. Now the defined tropics are not so stable and are becoming too hot for many species. This study is the result of doctoral work by lead author Chhaya Chaudhary at the University of Auckland and builds on a series of studies in a joint research group that delineates documents and data on taxonomy groups. Specifically, these include crustaceans, fish and worms. The data is taken from the Ocean Biodiversity Information System (OBIS), a free accessible online world database established by Professor Mark Costello of the University as part of the marine biology investigation, a global marine exploration program from 2000 to 2010. Recorded information about the time and location of species was compiled into latitude ranges and a statistical model was used. Use to calculate variables in sampling. Last year, Professor Costello co-authored a study that found that although marine biodiversity escalated and peaked at the equator during the last ice age 20,000 years ago, it was pulled flat before the status quo. global warming in the industrial era. This study uses fossil records of marine plankton buried in deep-sea sediments to track changes in species diversity over thousands of years. The latest research on a decade scale shows that this flat drag has continued over the past century, and that the number of species is now decreasing at the equator. This research, and other work underway, shows that the number of marine species declines when the average annual seawater temperature is above 20 to 25 degrees Celsius (varies with different species. ). As one of the lead authors of the current International Commission on Climate Change (IPCC) 6th Assessment Report, Professor Costello argues that these findings are of great significance. “Our work shows that man-made climate change affects marine biodiversity on a global scale across all species. Climate change is already here for us and is happening at an ever-increasing rate. We can predict general trends in species diversity, but due to the complexity of ecological interactions, it is currently unclear how rich marine life and fisheries will be. how to change according to climate change ”, said Professor Costello. According to a new study published in the journal Nature Climate Change, the rate of climate change in the depths of the world’s oceans could be seven times higher than current levels in the second half of this century even if greenhouse gas emissions have been significantly reduced. Different global warming at different depths has a major impact on the wildlife of the oceans, causing disconnections as species that rely on each other for survival are forced to move. Professor Anthony Richardson of the University of Queensland and CSIRO, who is also one of the 10 authors of the study, pointed out: “What really worries us is that when we move down deep in the ocean, the climate velocity moves downwards. transfer at different speeds ”. This can create a disconnection with species that depend on organic organisms of different layers. Tuna, for example, live in the middle layer with a depth of 200 – 1000 m, but they need plankton near the sea surface. Professor Richardson emphasized that the results of the study are of concern, with climatic speeds varying depending on the depth of the ocean and the tendency for species to move to be uneven. This may mean marine protected areas established to protect species or habitats may no longer work as species move out of protected areas into unprotected areas.

Climate change, if left unchecked, could destroy natural treasures in “biodiversity hotspots” around the world, scientists warn.

A global team of scientists has analyzed nearly 300 biodiversity hotspots on land and at sea. These are locations with a particularly high concentration of plant and animal species. Many of these hotspots include ‘endemic’ species, inhabiting only a single geographical location, such as an island or a country.

They found that if the planet heats above 3 ° C, one-third of the endemic species that live on land and about half of the endemic species living in the sea will face extinction. In mountainous regions, 84% of endemic animals and plants face extinction at these temperatures, while on islands it reaches 100%. Overall, 92% of terrestrial endemic and 95% marine endemic species face negative consequences at a 3 ° C increase, such as a reduction in numbers. Current policies are moving the world in this direction of about 3 ° C warming.

Among endemic species, there are some of the world’s most iconic animals and plants. Endemic species threatened by climate change include all lemurs that only exist in Madagascar; the blue crane – which is the national bird of South Africa; and the snow leopard, one of the most unique animals of the Himalayas.

Research shows that compared to widely available species, endemic species are 2.7 times more likely to become extinct if the temperature rise is not controlled. Since they are only found in a certain place, and if climate change changes their separate habitats, these species will inevitably disappear from the Earth’s surface. If greenhouse gas emissions continue to increase, places like the Caribbean islands, Madagascar and Sri Lanka may see most of their endemic plant species go extinct as soon as 2050. The tropics It is particularly vulnerable, with more than 60% of tropical endemic species facing extinction under the effects of climate change alone.

But everything is not necessarily over. If countries cut their emissions in line with the Paris Agreement then most of these endemic species will persist. In total, 2% of endemic soil species and 2% of endemic marine species face extinction if the temperature rises to 1.5ºC, and 4% at 2ºC. Strong commitments from global leaders ahead of the Glasgow climate change summit later this year could put the world on track to meet the Paris Agreement, and avoid the risk of treasures. The world’s most precious nature was destroyed on a large scale.

“Climate change threatens areas that are so rich in unique species of organisms,” said Stella Manes, study lead author and researcher at the Federal University of Rio de Janeiro. Found anywhere else in the world. The risk of permanently disappearing these species will increase more than 10 times if we miss out on the goals of the Paris Agreement. Biodiversity has more value than just seeing. The higher the species diversity, the better the health of nature, while also protecting against threats such as climate change. Healthy nature will provide indispensable sources of life for humans, such as water, food and materials, protect us from natural disasters, provide value for recreational relaxation and cultural connectivity, and morale.”

“Our research shows that a one-color and possibly very boring world awaits them,” said Wolfgang Kiessling, a marine expert from Friedrich-Alexander Erlangen- Nürnberg University and author of the study. We are ahead due to climate change. Organisms will benefit, while native species that contribute to the distinctive look of hot spots will disappear. ”

“This study found that species are geographically rare, especially those that live,” said Mark Costello, a marine expert from the University of Nord and the University of Auckland and author of the study. on islands and mountains, which are already in danger of extinction due to current climate change, these species cannot easily migrate to more favorable environments by their natural characteristics. that 20% of all species will be threatened with extinction by climate change in the coming decades, unless we act now. ”

According to Shobha S. Maharaj, an island expert from the Caribbean Journal of Environmental Science and Renewable Energy, and author of the study: “This study shows the relative risk of extinction due to climate change. with rare species living in the island area, it is 8 times higher than that in the mainland. The geographic rarity of these species makes them of global value to nature. Such species cannot easily migrate to more favorable environments and their end to extinction could lead to a global decline in disproportionate species.

A section of West Lake embankment on Quang Khanh Street has been used by people living around this area to grow clean vegetables for about 2 years.

The vegetable garden here is plentiful and diverse in varieties from leafy vegetables, short-term vegetables to spice vegetables. Because it is close to the edge of the lake, the watering problem is always solved.

Mr. Luu (security guard at an apartment in Quang Khanh, Tay Ho) said that there are several families here growing vegetables together. Every day, in the early morning and late afternoon, people will water and take care of vegetables.

The soil is poured into concrete holes like the rock-hole cultivation of the Ha Giang people.

Vegetables here are grown according to the season, depending on the type of vegetables that will be harvested after a few weeks.

Leafy vegetables such as spinach, spinach, amaranth … give quick harvest but quickly run out. Therefore, people here like to intercrop spices because they produce more and last longer.

In addition to watering, people here have to constantly catch worms, and snails destroy every day.

Ms. Nguyen Thi Hoa, from Vinh Phuc (as a housekeeper for a family on Quang Khanh street) regularly watered and cared for the vegetable garden twice in the morning and afternoon.

Ms. Hoa said that people had to buy land for 5,000 VND / bucket and then pour it into the rocks to grow vegetables.

“Growing vegetables like this is very difficult because the amount of soil is less, the nutrients are also low, so the vegetables grow slowly but not too large. But when growing by themselves like this, we are more assured because the vegetables are self-grown” – Ms. Hoa adds.

Taking advantage of about 100 meters of the embankment to grow vegetables, Ms. Hoa has enough vegetables for herself and her host family. Sometimes the vegetables grew too fast, she even had to give them away.

Without using chemical fertilizers or plant protection drugs, vegetable growers here have to take care of themselves from weeding, catching deep to applying microbiological fertilizers to ensure absolute clean vegetables.

Aquarium or aquatic shrimp is a common term for many types of shrimp. With a size slightly larger than the tip of a toothpick, the shrimp have many different names such as red cherry, bee, tiger, Kinh kong, red nose, white dot, green, yellow pumpkin … depending on the type.

This ornamental creature has a colorful appearance, eats vegetables in a glass tank, cleans the environment, so it easily “attracts” many players. Most of the common types of shrimp in Vietnam are originated from Japan, Taiwan, Indonesia …

Although ornamental shrimp is popular, it is quite “picky” for farmers because the life expectancy of this species is very low, susceptible to disease and highly contagious. At the same time, breeding shrimps requires farmers to have high technical skills.

.

Mr. Le Tuan Anh (Ha Huy Tap ward, Ha Tinh city) revealed: Shrimps are sensitive to weather, food, water and light so players need to be very clear about their pathology, closely monitor abnormalities to avoid them falling ill.

The most important factor for the beautiful color and healthy life of the shrimp is the water quality.

If you see shrimps swimming weak, lethargic need to change the water immediately. If there is discoloration or fading in the aquarium shrimp, the water quality is deteriorating. (In the photo are kinds of shrimp that are quite easy to live like: RC red shrimp, Chocolate shrimp, Blue Dream …)

In the summer, players of ornamental shrimp in Ha Tinh also struggle to maintain the ideal temperature because most of the ornamental shrimp lines prefer cool temperatures. At temperatures higher than 28 degrees Celsius, shrimp will not be able to lay eggs, even fading.

In order to maintain the ideal living environment for shrimp, players also have to invest in some additional tools such as filtration system, projector lamp, background distribution, cooling fan, PH meter, thermometer …

Shrimps are omnivores that do not require special food. In addition to algae, harmful algae, and plant foods, players can also add some specialized foods.

The cost of shrimp depends on the type, pattern, color of the shell and its rarity. The most popular and affordable one is the Red cherry (cherry shrimp) about 20 to 50,000 VND / pair. More expensive, there are types of yellow shrimp, black shrimp, Kingkong, Panda, Red Ruby … from 100,000 VND to several million / animal. In particular, there are types of hybrids, mutant shrimp that are offered for tens of millions of dong.

Although the hobby of playing shrimp is a bit fussy, with many people taking care and cherishing each small shrimp becomes a hobby. Mr. Nguyen Cao Cuong (Bac Ha ward, Ha Tinh city) shared: “After a long and hard day, the time I spent watching the shrimps brought me a feeling of comfort. Taking care of shrimp also trains me to be patient, because it is difficult to be impatient and impatient to control the care of the tank and keep the shrimp ”.

This worm is only available from September to October of the lunar calendar. Therefore, the selling price of bamboo in the market is quite high, 550,000 VND / kg (frozen) and 600,000 VND / kg (fresh goods). Photo: Youtube.

Despite its terrifying appearance with limbs and thorns, cassava leaf silkworms are hunted by many women to enrich their husbands with the price from 110,000 to 150,000 VND / kg. Photo: Vietnamnet

In some provinces such as Phu Tho, Tuyen Quang … raising cassava leaf silkworms has become the main source of income for many households. Photo: Vietnamnet

There is a picture that is not different from a worm, even scaring many people, but it is a specialty that city residents are looking for at prices ranging from 350,000 to 600,000 VND. Photo: Internet
