Taiwan Air Force F-16. The Taiwanese military has announced plans to sell its old F-16 radars after Taipei’s fighter squadron received new radar systems. Taiwan’s F-16 fighter aircraft is being upgraded with the new AN / APG-83 AESA radar as part of the retrofitting of the F-16 Block 70 version. However, the old APG-66 radars are still serviceable and valuable in the international arms market, Liberty Times reported. A source familiar with the matter has pointed out that APG-66 radars could also be installed on F-16A / B fighter jets, which are still in service with foreign air forces. After Taiwan completes the retrofit of its jets, a batch of more than 100 APG-66 radars will be sold in accordance with US regulations, with profits transferred to Taipei’s treasury. The value of the old radars has yet to be determined, the source said. Taiwan purchased 150 F-16 fighters from the US in 1992 and received them in 1997. According to the Northrup Grumman group, the new AN / APG-83 features high-resolution synthetic aperture radar mapping in all weather conditions to show pilots a large surface image for item identification. target and more accurate attack information.

Illustration. One of the most isolated places in the world is the Vale do Javari region in the Amazon forest area. It is home to 14 Amazon tribes and they do not have any contact with the outside world. The area covers an area of ​​86,000 square kilometers, which is about the size of Austria. According to The Guardian, in March 2019, an expedition was organized by the agency for indigenous Brazilians, with the aim of easing tensions between two rival indigenous groups in the Vale do Javari region. The slums Looking at a map of a city, you will see clearly indicated streets, parks, highways, and buildings. However, in some cities, there are areas that do not appear on the map. According to BBC Future, in cities like Rio de Janeiro in Brazil and Lagos in Nigeria, the slums are not depicted on the map because these areas are not the top priority here. In fact, many of the largest cities in the world have large communities with impoverished populations that live there and never appear on maps. Cenotes Yucatán Cenotes, Mexico According to photographer Klaus Thymann, this underwater cave system is located in the Yucatán peninsula of Mexico. This cave system is thousands of kilometers long and has not been explored since the Mayan period; and it doesn’t exist on any map. Klaus Thymann begins the exploration of the Yucatán Cenotes cave system and takes pictures of it, with a desire to raise awareness about this unique cave preservation. Rivers flow through caves and form the aquifer of Yucatán and support about 11 different ecosystems. Gangkhar Puensum Mountain, Bhutan This is probably the tallest mountain in the world that has not been conquered yet, it is estimated its height is about 3,000 meters. This mountain has not been mapped and unlike others, it has yet to be explored for spiritual reasons. For the locals, some areas on the mountain have been refugees for Buddhist saints for centuries and the mountains themselves have been home to gods and goddesses. Patagonia, Argentina and Chile regions According to Geospatial World, Patagonia region stretches almost as far as Antarctica. It is littered with tropical forests, glaciers, so remote and inhospitable that it is almost impossible to map. Mapping this area is a difficult and dangerous task, as the ice fields here are comparable to those of the polar ice. Northern mountain forest complex, Myanmar The US economic sanctions against Myanmar for many years have helped the country successfully protect most of its primary forests from the effects of economic development. But this seems to be changing, the area of ​​primary forest is disappearing and with it many vulnerable species. However, it is very difficult to assess the damage because there are almost no roads in the forest and very few people can come in to assess the situation. This means primeval forests are likely to disappear before it has been fully mapped. Cape Melville Cape, Australia Cape Melville is a cape off the coast of Queensland. And a surrounding wall made of granite has separated this headland from human exploration. Although the habitat inside the rainforest in the headland is effectively protected, it also means that the area is virtually unmapped. North Sentinel Island, India North Sentinel Island is part of the Andaman Islands between India and Myanmar. Due to the local population’s hostility towards outsiders (who are not Sentinel residents), this place has not been explored and mapped. In 2006, a boat carrying two fishermen drifted into the farmland of North Sentinel Island and they were killed there. Since then, there have been other reports of tribes firing arrows at passing helicopters. Ocean bottom The vast ocean floor and the bottom of the five oceans cover up to 71% of the earth’s surface. Even though we have mapped the ocean floor, according to The Conversation of Australia, the map is clearly low resolution. In fact, our map of the ocean floor is less detailed than our map of Mars, Moon and Venus. That is because the water flow has blocked the mapping tools. But oceanographers are still researching and conducting more perfect, detailed ocean floor mapping. Sandy Island, South Pacific Some locations that actually exist are not mapped, while areas that do not exist are shown on the map. One example is Sandy Island located in the south of the Pacific Ocean. This island appears on marine maps, world maps as well as on Google Earth and Google Maps. But when the scientists began to study this supposedly located halfway between Australia and New Caledonia, they discovered it didn’t exist there and probably never existed. Even so, the island has been on the map for many years and it is thought that it was just a mistake.

Robotic dogs are trained to fight with French military trainees. According to the Daily Mail, Spot robot, priced at $ 75,000 (equivalent to 1.7 billion) was developed by Boston Dynamics (formerly a US robotics company but now owned by the umbrella corporation. Korea Hyundai as of December 2020). Close-up of robot dog worth 75,000 USD (1.7 billion VND). The robot dog is suitable for both indoor or outdoor use, can map the environment, feel and avoid obstacles, climb stairs and open doors. In particular, it can perform dangerous missions in a variety of harsh environments such as nuclear plants, offshore oil fields and construction sites or even on battlefields. Robotic dogs are trained in 3 combat missions with French military trainees. Despite being researched and developed by Boston Dynamics for many years, the robot dog was released to the market last June. One of the first customers to buy it was billionaire Elon Musk – founder of SpaceX Technology Corporation (SpaceX). The robot dog is currently one of the robots on the payroll of the French army. Robotic dogs proved to be especially useful in urban combat. “This is an expensive robot, especially for civil or police applications. New York Police (USA) are also testing it under the name Digidog. It has also been tested for anti-Covid antiseptic missions. -19 “, Clément Levilly, a robot distributor in Europe told Ouest France. The list of customers to buy this expensive robot dog includes billionaire Elon Musk. The military school Saint-Cyr has applied to robot dogs for 3 training scenarios – one is an attack mission: capture intersections; two are defensive missions during the day and at night; Finally, the combat missions in urban areas.

Face mapping associates skin areas with various internal organs. Thousands of years ago, when this method was first developed, the location of the pimple helped doctors diagnose internal health problems. Today, this practice is still used regularly to help eliminate health-related factors or inadequate lifestyles that cause acne. You can understand your overall health based on the location of the pimple on your face. Photo: boa forma. Forehead Dr. Amanda Doyle – a dermatologist in New York, USA – said the location of acne in the forehead often related to the digestive system. These are signs that your body is having difficulty breaking down food or liver problems. In addition, blemishes on the forehead can be the result of stress, unhealthy diet, or lack of sleep. Try cutting out sugar and processed foods from your daily menu, limiting staying up late, and finding ways to relieve stress. Forehead pimples are symptoms of digestive problems. Photo: gettotext. If you have bangs, forehead pimples will appear as excess oil and bacteria are trapped under the hair. What’s more, girls tend to touch their faces all day long to adjust their hair. This makes acne worse. You should use a gentle chemical exfoliant 1-2 times a week to remove excess oil build up, and minimize pore clogging. Nose This is a popular acne spot because the concentration of many oil glands leads to clogged pores. Use moisturizers that are mildly formulated, suitable for your skin, to reduce oil intake. You need to regularly exfoliate your skin and use pimple pads for the nose area. Photo: Sohu. Mother Dermatologist Amanda Doyle says blemishes on the cheeks could be a sign that your body is consuming a lot of sugar. You need to limit sweets and change your diet properly. According to the Top Doctors , cheeks acne is also caused by the lifestyle of each person. In men, shaving cream is a contributing cause of this condition. While foundation or cosmetics is the “culprit” that makes acne appear on female cheeks. If you have persistent pimples on your cheeks, it could be the result of exposing your skin to a dirty pillowcase or phone screen. A study conducted by University College London revealed that most of the phone surface is contaminated with bacteria. So, change your pillowcase at least once a week and wipe your phone often with a disinfectant towel. In addition, you should not bring your phone to the bathroom or toilet. Cheeks acne comes from the daily routine of each person. Photo: flora health. Chin and jaw contour Acne around the chin and jawline are the result of hormonal fluctuations. Women are more likely to get acne in this area than men. Flare-ups occur about 7-10 days before a woman’s menstrual cycle. These hormones stimulate oil glands and clog pores. People need to avoid dairy, processed foods and sugars as these affect hormone levels, aggravating acne. Drinking enough water every day is an easy way to have beautiful skin. Photo: herworld. Around the mouth Pimples around your mouth are caused by an allergic reaction to lipsticks or food residues that have stuck on your skin. In addition, lip hair follicles are blocked with oil and dead skin is also a common cause. If acne recurs around the lip contour, remove the make-up before going to bed and wipe your mouth after eating. In addition, you should create a habit of exfoliating your lips with natural products such as coconut oil, coffee … 2 times / week. The position around the mouth is quite sensitive. Therefore, women should pay attention in their care. Photo: Elle. Hair roots This position is primarily caused by hair care products. If your hair has not been washed, oil will form on the roots, clog pores. In fact, acne occurs because products used for hair coloring and styling contain chemicals that can irritate the skin. Why are you prone to acne? Certain daily habits can cause breakouts, affecting your appearance.

Axolotl is a species of salamander being hunted by the world science world. The reason is its unique feature: Many lost parts can be reproduced.

According to the New York TimesAxolotl also has an unusual feature compared to other amphibians that do not undergo molting, change shape. They have a pale pink, yellow or gray, black appearance; Spotted body with a smiling face.

Today, this animal is in danger of being threatened by the environment and by human hunting. Axolotl survives only in the canals of Lake Xochimilco, the southernmost tip of Mexico.

The mystery of the genome of a self-regenerating animal

Researcher Randal Randal Voss, University of Kentucky, USA, said: “It is difficult to find things that they cannot replicate: From limbs, tail, spinal cord, eyes, even the retina in some “We have also seen the process of regenerating half of their brains.”

Thanks to this feature, the genome of Axolotl has become something of interest to the scientific community. Recently, in an upcoming article to be published in the Proceedings of the National Academy of Sciences (PNAS) on April 13, geneticists have a clearer view of the salamanders genome. This is on the chromosome scale, in the folded form. The study was chaired by the authors at the Vienna Center for Biology, BioCenter Institute for Molecular Pathology, Austria.

The study looks at how the genome of Axolotl folds inside at the molecular level and the position of the DNA sequences that regulate the genes involved in the regeneration and healing of cells. When fully stretched, each human DNA strand is longer than 1.8 m. However, Axolotl’s DNA strand is more than 9.1 m long.

“This work has arranged the DNA fragments in the Axolotl genome in the right order, as if it were on a chromosome. This is very important because in all vertebrates, genes are turned on and off with a controlled sequence located quite far from them, ”says biochemist Elly Tanaka, Vienna Institute of Molecular Pathology, BioCenter. about Axolotl but not participating in this project, reviews.

She also said that the study of the authors at the BioCenter Molecular Pathology Institute is very important because it will answer the question of whether the regeneration mechanism in Axolotl can be activated in humans.

After regenerating the entire gene in the folded form of Axolotl, the authors expect to simulate it in 3D in the future.

Two mysterious genes of Axolotl

According to Professor, Dr. Parker Flowers, Craig Crews Laboratory, Yale University, USA, Axolotl regenerates, self-healing most organs and organs after any injury. Therefore, it is difficult to have any injuries to kill this salamander.

If scientists find the genetic basis for the regenerative ability of Axolotl, they may discover something unprecedented. It is a way of restoring damaged tissues in humans.

But that job is not easy. Because the characteristics of the species Axolotl are not like humans. They have a larger genome than any other animal that humans have ever sequenced. This genome is even 10 times larger than the entire human genome.

At the end of January 2020, Professor Parker and his colleagues in the magazine post eLife revealed they have found the key to these problems. The authors found a way to disrupt the complex genome of the salamander Axolotl and identify at least two genes involved in post-traumatic body regeneration.

According to the Science Daily, the advent of next-generation gene-editing and sequencing technologies has allowed researchers to list hundreds of gene candidates that can reproduce the extremities. However, the giant size of the Axolotl genome produces repetitive DNA fragments, making it difficult to dissect and analyze them.

Researcher Lucas Sanor, co-author of the Craig Crews lab project, used multi-step gene editing to record baseline markers, tracking 25 genes believed to be involved in the regeneration process. Genus in Axolotl. Thanks to that, they identified two genes in blastema dividing cells responsible for regenerating part of their tail when injured or severed.

But that’s not all. Professor Parker emphasized that Axolotl’s body still has many similar genes. And humans have similar DNA with Axolotl so scientists can discover how to activate tissue, cells speed up wound repair, regenerate lost parts.

Decoding the entire gene of Axolotl for the first time

Before the study of Professor Parker Flowers and colleagues, at the end of November 2018, the group of authors at the University of Kentucky, USA, published the most complete simulation of Axolotl’s DNA. Research published in the journal Genome Research, is considered to pave the way for transformations in human regenerative medicine.

Many animals are able to perform some degree of regeneration and self-healing. However, Axolotl is the only species that is nearly limitless in terms of this ability. Associate Professor, Dr. Jeramiah Smith, University of Kentucky and colleagues decided to find answers about the healing superpower of Axolotl through sequencing all genes.

Based on previous research, the authors have mapped more than 100,000 pieces of DNA onto chromosomes, the genetic makeup in the nucleus of each cell. The Axolotl genome is the largest product assembled at this level.

The authors used a design mapping method, which relies on the fact that the strands of DNA are physically close together on one chromosome and tend to move together. To determine the specific DNA of Axolotl, they grafted Axolotl with the tiger salamander – a close relative. They were then mated back to generation F1 with purebred Axolotl.

Tracking genotypes on 48 out of all F2, they were able to deduce which DNA sequences belong to the Axolots and where they are located in the 14 chromosomes of amphibians. During the study, the authors identified a genetic mutation that causes heart defects in Axolotl.

“Just a few years ago, no one thought it was possible to decode genomes with more than 30 GB capacity. Now, we have many methods to approach and open up the ability to decode large genomic animals more often, “says biological researcher Jeramiah Smith.

The team also hopes that understanding the axolotl’s post-sequencing genome will help in future medicine. “Now we can go into the genome sequence, find out what makes this salamander strange. Hopefully one day, we can make the collected information useful for human therapy, the potentials that may not be fully exploited of each part of the body ”, Mr. Voss identify.
