You probably never thought that an animal could live without a head, heart, or bones. In fact, this species existed 500 million years ago and exists to this day, in addition they are considered “cousins” of the ancestors of many species of vertebrates today. The vertebrate family of today is extremely prosperous, with more than 60,000 members, all of them with different looks, habits and temperament, but this “cousin” has only one child. Only alive, they are called Amphioxus – Van Xuong fish, this species is also considered living fossils. Although Van Xuong fish is called fish and at first glance it is very similar to fish, it is not actually fish. On our planet today, most animals that exist are vertebrates, such as horses, cattle, sheep, chickens, dogs, cats, tigers, ba … Of course, there are us as well. What makes this particular “fish” so exotic and unlike any fish is that they are vertebrates, have no vertebrates but are still grouped with vertebrates, cord animals and form the Chordate branch. Biologists believe that Van Xuong fish are animals during the transition from invertebrates to vertebrates, today they are considered to be the ancestors of fish, but they are completely not fish. The skin layer of Van Xuong fish has 2 main layers, the outer epidermis and the dermis on the inside. Unlike most vertebrates, their epidermis has only 1 cell layer, while the epidermis is underdeveloped, mainly composed of colloid or elastic connective tissue. There are more than 66,000 species of animals in the order Phylum Chordata. The most remarkable thing is that vertebrates make up the largest proportion, with more than 66,000 species, the main caudal subsector is the sea level, and there are currently about 3,000 known species; and head vertebrates, only two families of fish Van Xuong and fish Asymmetron – there are 30 species. In fact, the skeleton of this fish is the wire that runs along the body and back from the tail to the head. The gill region, the skeleton, is a network of horizontal and vertical interconnected rods. The fins and tentacles are also supported by the connecting rod. Their central nervous system is a neural tube running along the body, located above the spinal cord but not reaching the end of the spinal cord, wrapped in a protective glue film. Although the Van Xuong looks like a fish, the biggest difference between it and its vertebrates is that it does not have a real head, sensory organs such as smell, sight and hearing, even a skull. The teeth are also something too fictional for them. This animal has only a bunch of elastic “legs” on the head to play the role of supporting the body. The most amazing thing is that it doesn’t even have a heart; instead, it relies on the beat of part of the blood vessel to carry blood. Their musculoskeletal system is less dissociated and typical dissociated. Therefore, muscles can only ensure simple bending movements, consistent with the lifestyle of being buried in the sand. The muscular system consists of many muscles (myomera), arranged from the front end to the posterior end of the body. The muscle segments are intersected by septum by connective tissue (myosepta). The muscles on both sides of the body are arranged alternately with comb teeth together. As a result, when swimming, the Pangasius swim, its body bends along the horizontal plane. Amphioxus is widely distributed in the shallow waters of the ocean, and Qingdao and Xiamen in China are their primary habitats. In addition, there are coasts of Southeast Asia and coasts of California and Florida, Norway, the Mediterranean and Africa. Due to its rich nutrition and delicious taste, Van Xuong fish is considered a delicious traditional dish in Southeast Asia. Van Xuong fish is 3 to 5cm long, the morphology is very strange. The long and flattened body looks almost like a burden. The whole body color is pink, semi-transparent, the parallel longitudinal muscle fibers can be seen. They have no scales, no fins, no vertebrae, and their internal organs are just a rhythmic, rhythmic, complex. No senses like eyes, nose, or ears. There is no differentiation to the digestive tract. Apart from the mouth and throat, just a piece of intestine that leads straight to the anus. Van Xuong fish often follows tidal water to swim in estuaries where the seabed is shallow, almost unable to defend themselves but capable of penetrating into the ground. Their lifespan is about 3-4 years, they often bury half of themselves in the sand, while the other half is exposed to the plankton from the river. Their muscles are less differentiated, so they can only move in water by simple bending movements. When not moving they often bury themselves in the sand. The way of respiration of Van Xuong fish is similar to that of fish. They vibrate to inject capillaries (mouth tassels) to carry the stream of water from the gill slits. The wall of the gill slot has many blood vessels, where gas exchange occurs.

On April 29, at the Van Xuong spacecraft launch center in Hainan province, China successfully launched the first module of the Tianhe space station with the Truong Chinh 5B rocket, marking an important step in the build the country’s own space station. However, instead of falling to a predetermined place in the sea like the previous rockets, the central stage of the Truong Chinh 5B boosters started spinning around the Earth in a low orbit in a state of out-of-control. With a weight of about 21 tons, 30m long and 5m wide, the remnants of the Truong Chinh 5B rocket are flying in orbit around the Earth every 90 minutes / rev, at a speed of 27,600 km / h at an altitude of over 300 kilometer. Since the end of last week until now, this remaining part has decreased altitude by nearly 80km. According to the observations of underground amateur astronomers, this missile is in a very unstable state. Some calculations show that the central floor of the Truong Chinh 5B missile will plunge into the atmosphere on May 8. When it crosses the Earth’s atmosphere, it could be burned, but it is likely that large pieces of the missile will remain and will fall scattered over an area of ​​160km wide. Worth mentioning, this is not the first time that China’s Truong Chinh 5B missile has fallen into a state of out-of-control during the biosphere. In May 2020, a similar incident happened. Beijing is expected to have at least 10 more similar launches, bringing all additional equipment into orbit, before completing the station by 2022. China’s Truong Chinh 5B missile was launched into orbit on April 29 at the Wenchang launch pad, southern China. . Prior to the US Space Command’s forecast that the 2021-035B Truong Chinh 5B (Long March 5B or Chang Zheng 5B) missile core, called 2021-035B, was capable of falling uncontrollably on Earth on the day. May 8-9, many people questioned: Will Russia or the US plan to use the missile to shoot the core of the Truong Chinh 5B missile, to save the planet’s citizens? On May 6, the US said it was tracking the object’s path, but had no plans to shoot it down. Cosmic garbage Australia currently holds the record as the country that contains the largest space waste in the world. In 1979, the 77-ton American SkyLab space station disintegrated in Western Australia, leaving the area around the coastal town of Esperance splashed by debris. Although no deaths or serious injuries have been reported from being hit by these cosmic debris, it is quite dangerous. Just a year before the fall of SkyLab, a Soviet remote sensing satellite, Cosmos 954, crashed into a barren area of ​​Canada’s Northwest Territory, spreading radioactive debris over several hundred square kilometers. As the Cold War was at its height, the nuclear sensitivity of the Cosmos 954 led to unfortunate delays in locating and cleaning the wreck. Who has to pay for cleaning? International law sets out a compensation regime that applies in many cases of damage on Earth, as well as when satellites collide in space. The 1972 conventions, a United Nations treaty, impose liability for the damage caused by space debris, which includes a regime of absolute liability as they fall to Earth like fragments. crumbs. In the case of Long March 5B, this would impose potential liability on China. The new treaty has only been invoked once before (for the Cosmos 954 incident) and therefore may not be considered a incentive. Of course, this legal framework only applies after the damage has occurred. In 1978, a Soviet nuclear-powered satellite crashed in northern Canada, resulting in a $ 3,000,000 fine for the tundra radioactive cleanup for Canada.
