About 55,000 years ago, human beings came to Australia; 4.5 million years ago, cattle birds were exterminated with dozens of other giant species, including bags and rats. But only indirect evidence links their extinction with the advent of humanity. Although North American humans have left clear evidence of hunting and slaughtering large animals, such as the bone or stone-throwing point where the mortal remains of bruising marks, these do not exist in Australian animal remains.

A possible and conclusive evidence emerged in 2016, when researchers linked the burning of eggs near the southern and western coasts of Australia to the birds of cattle. “Many (egg shell) have been burned, which means that they are consumed by human beings.” Gifford Miller, a global scientist at Bold, Colorado University.

Other researchers, however, believe that these eggs are too small to belong to stadium birds and that they belong to another small bird with a chicken and chickens.

“In order to prove that these eggs (which are similar to the eggs or small eggs) belong to megabirds, we need some independent methods.” Miller said.

The research team attempted to extract ancient DNA from the stone eggs, but has not yet produced results. Beatrice Demarchi, a protetics expert at the University of Turin, Italy, who identified the eggs together with Miller, said: “The eggs are too old and the climate is too hot”. The Panel then turned to egg shell protein.

The egg shell is rapidly formed within the egg pipe of the birds — a 24-hour period in which protein can be captured into the stipulation and mineral crystals that shape the eggs. Demarchi stated that these proteins “shall not be affected by environmental pollution, but only by temperature and time”, on the basis of which scientists can restore protein residues related to egg formation.

Tribute of the ancient birds in the Wall

Demarchi stated that when the Panel compares these protein sequences with the protein series in modern eggs, it found that they are completely different, and that the former do not belong to all existing groups of terrestrial birds. Researchers wrote in their paper that this made it the only possible possibility for cattle-breeding birds considered to be close relatives.

Worthy, which did not participate in the study, was impressed by the results. “Researchers have accepted the challenge well — evidence of protein seems quite strong”.

However, due to insufficient evidence of osteoporosis, thrones still exist: why is this large bird yielding relatively small shell eggs? “If they are opposite, then it is a very large bird, whose egg is the smallest of known birds.” Worthy said that “we may need to find an egg shell next to a group of bird remains to consolidate this link.”

Eggs burned have shown that the first arrivals in Australia will steal and eat — rather than direct fighting with large birds. “Humanity is likely to succeed in catching up with birds.” Miller stated that “the most effective way of causing extinction of species is to capture their children”.

It was announced at the scene that the basic display of “Jijin Guanghua” in Shanxi bronze Museum won the top ten exhibition awards of national museums

Shanxi bronze Museum, a branch of Shanxi Museum, is a major measure of the Shanxi provincial Party committee and the provincial government to “build a new highland of Shanxi culture”. The “Jijin Guanghua” theme exhibition is the basic display of Shanxi bronze Museum, with an exhibition area of 11000 square meters and more than 1450 exhibits. It is the largest, richest and most complete thematic display of Chinese bronze culture in China, which is composed of five independent chapters, And complementary topics.

Zhang Yuancheng, President of Shanxi Museum (second from the left in the first row), took the stage to receive the award

Special exhibition of three cultural relics entities. “Chinese imprint” takes history as a clue, interprets the relationship between “ware” and “country”, and tells the special position of bronze culture in the development of Chinese civilization; The spring and Autumn period of rites and music takes the rites and music system as the core, discusses the relationship between “utensils” and “Rites”, and explains the spiritual connotation of bronze culture in rites and music civilization; “Skill model” takes craft as the main line to show the light of wisdom of bronze cast by Chinese ancestors.

Two special exhibitions on science and education. “Exploring the secluded and seeking victory” highlights education, expands knowledge, activates experience and combines teaching with fun; “Digital bronze” highlights science and technology and presents fresh history and culture through modern technologies such as digitization. The six characteristic exhibitions make the museum closer to public life and make it easier for the audience to understand the thick bronze culture.

“Jijin Guanghua” Prelude Hall

Shanxi bronze Museum has been built and opened for more than a year. It is committed to building a cultural communication platform with knowledge, interest, story, temperature, hope and vitality. Focusing on the theme of “Jijin Guanghua” basic display, it carried out cooperative research with domestic and foreign scientific research institutions with an open concept, and successively planned and launched a series of bronze themed exhibitions, special lectures and rich and colorful educational activities; Adhering to the concept of “Museum, art and life”, we have developed bronze themed cultural and creative products to meet the audience’s good wishes to bring bronze culture home; More than 1500 media at all levels in China publicized and reported the display of “Jijin Guanghua”. The topic of “Shanxi bronze Museum” on Sina Weibo exceeded 100 million times, winning wide praise from all walks of life. In this evaluation, Shanxi bronze Museum has been unanimously recognized by the judges, experts and colleagues of many participating museums.

The promotion of the top ten boutique exhibitions of national museums has been held for 18 times. It is the highest award of domestic museum exhibitions and is known as the “Oscar” in the field of museum exhibitions in China. A total of 25 domestic exhibitions and 3 entry-exit exhibitions in this promotion activity entered the final evaluation link. After fierce competition and careful discussion and evaluation by expert judges, ten projects such as the “Jijin Guanghua” basic display of Shanxi bronze museum were finally selected as the “top ten exhibition Excellence Award of national museums in the 18th (2020)”.

This award is also the third time that Shanxi Museum won the highest level award of National Museum exhibition after winning the 7th (2005-2006) National Museum top ten Exhibition Award and the 12th (2014) National Museum top ten Exhibition Award.

In the key year of the beginning of the 14th five year plan, this will certainly become a new starting point for the high-quality development of Shanxi Museum. At the same time, it is also a cultural gift presented by Shanxi Cultural and Expo circles to celebrate the 100th anniversary of the founding of the Communist Party of China!

It home learned that the report pointed out that the scale of China’s network market was US $10.24 billion (about 67.789 billion yuan), an increase of 12.1% compared with last year.

The park’s position as the main battlefield of economic activities has been further highlighted, and its scale and agglomeration effect have been greatly improved. Last year, the revenue of Yangpu Economic Development Zone, Haikou Jiangdong new area, Hainan Ecological Software Park and Haikou Fuxing City Internet Information Industrial Park exceeded 100 billion yuan; The tax revenue of Yangpu Economic Development Zone exceeds 20 billion yuan and that of Hainan Ecological Software Park exceeds 10 billion yuan.

Leading industries have gradually gathered and the development direction has become clearer. Hainan Ecological Software Park, Haikou Fuxing city digital economy industry, Yangpu Economic Development Zone Petrochemical new material industry, Dongfang Lingang fine chemical industry and Haikou pharmaceutical Valley pharmaceutical industry are developing well, and industrial clusters have been preliminarily formed. The future industrial development of Boao Lecheng medical and health care, yazhouwan science and technology city Nanfan and deep sea has taken shape and has the conditions to develop.

Early arrangements were implemented one after another, and the policy of Hainan free trade port was implemented in the park. The preferential tax policy of “two 15%” was fully implemented in 11 parks; The policies of “tax refund at the port of departure”, “registration at the port of registry”, “filling of bonded oil”, “list of raw and auxiliary materials”, “import tariff reduction and exemption of operating vehicles” and “30% tariff exemption for processing value-added” have been implemented and gradually promoted in Yangpu and other parks, and the policies of “financial leasing”, “qdlp and qflp” have been implemented in Haikou Jiangdong new area and Sanya central business district. At present, the main policies of Hainan free trade port have been implemented in the park.

Positive progress was made in reform and innovation. Boao Lecheng International Medical Tourism pilot area issued the province’s first park system integration and innovation scheme, taking the lead in carrying out international cutting-edge clinical real-world research in China. Yazhouwan science and technology city explores the mode of “legal institution + platform company”, uses the two hands of “market” + “specialty”, focuses on the problem of “unwilling, unable and unable”, makes use of the advantages of legal institutions, fully mobilizes the enthusiasm of all parties, gives full play to the resources and professional advantages of the two types of platform companies, the holding platform leads the development and financing, and the central local cooperation platform assists the construction of development projects and professional investment promotion, from the management system, development mechanism, investment and financing In terms of industrial introduction, a new road has been opened. In just two years, the park has entered the fast lane of development. Boao Lecheng and Haikou comprehensive protection zone make full use of the “franchise policy” to effectively lead the introduction of industries, and the highland situation of industrial platform is beginning to take shape. The reform of the investment and financing system of Yangpu Economic Development Zone and Wenchang international space city is also about to be solved. There are many highlights of system integration innovation, “minimalist approval” has been comprehensively promoted in 10 parks, and many measures such as “comprehensive reform of temporary land administrative approval” in Haikou high tech Zone and “e-enterprise benefit” in Jiangdong new area have continuously optimized the business environment.

The listener, Ms. Liu, said:

Ms. Liu: the intersection of Junfu road and Choufu road is at the west gate of Longxi community. The sidewalk on this road has been in disrepair for a long time. Especially in rainy weather, it will lead to water in the whole road area, and the bricks on the pedestrian crossing have been scattered. I feel there are some potential safety hazards, so I want to ask the teachers of our department to coordinate for us.

Ms. Liu: what should be important is that there is a big pit in the green belt, which has not been filled up. In addition, there is a power pole on the pedestrian road, and there is no sign on the power pole, and there are exposed construction muck and so on at those positions below the power pole. We have contacted the community secretary and are very enthusiastic to help us solve the problems, including finding the property, that is, the property of the community, including our Zhonghai real estate, but they all say that this thing is not in the area under their jurisdiction.

Urban construction section: if Longxi is used, I can confirm that it should not be within our jurisdiction, because Longxi belongs to commercial housing.

Urban construction section: I know that there are resettlement houses outside the community. I mean that you have resettlement houses in Huashan, that is, in area a and area B. If this area is outside the road, we can say that we are not sure whether it is the second construction or whether it has been handed over, but if you say Longxi, we are not responsible for the roads outside. It should be the developers. In this case, you can contact the urban management of the sub district office, because they are responsible for the roads in the whole Huashan Area.

Urban management section of Huashan sub district office

Urban management department: according to this location, we have to go to the road patrol first to determine this section, because sometimes our word-of-mouth may be different from its actual location. On our side, we will find the relevant department to confirm the responsible unit and call you back at that time.

Soon after, the reporter received a reply

Urban management department: the caller reported the location of the west gate of Zhonghai Longxi road and the east of Choufu road. Let’s confirm that it is on the south side of Junfu road. That road over there belongs to Zhonghai real estate. Our law enforcement team inspected the scene and found that it was under repair today.

It is reported that Hamilton will buy Chelsea club together with a consortium led by Sir Martin Broughton. Hamilton said: “Chelsea is one of the largest clubs in the world. When I hear the news that it can be acquired, I am very happy to have the opportunity to be part of a great cause. When the Jazz explained to me the objectives of the consortium, I was very excited because it is in line with my values.”

In addition to Hamilton, American tennis star Serena Williams also decided to participate in the acquisition. Hamilton said: “I talked to Williams about this. When she learned that I was involved in the acquisition, she very much wanted to join.”

It is worth mentioning that Hamilton, an Arsenal fan, is now involved in the acquisition of Chelsea, which makes him ridiculed, But he said: “when I was a child, I supported different teams, but my sister forced me to support the Gunners, so I became an Arsenal fan. But my uncle Terry is a Chelsea fan, and I have watched many Arsenal Chelsea games with him. As a child, I still dream of becoming a member of the club, and now is a good opportunity to practice.”
