　　CCTV News:On June 8th, the the State Council Press Office held a series of press conferences on the theme of "Opening by Authorities". According to the press conference, in order to improve the emergency rescue capability, the construction of various rescue forces has been growing, and all six national regional rescue centers have started.

　　China is building an emergency rescue force system with China characteristics, with the national comprehensive fire rescue team as the main force, the professional rescue team as the coordination, the military emergency force as the assault, and the social forces as the auxiliary. The national comprehensive fire rescue team is the main force of emergency rescue. In the past, it mainly put out fires, but now it undertakes the comprehensive rescue task of all kinds of disasters and major emergencies.

　　At present, six national regional rescue centers have all started. The Emergency Management Department also made overall plans for the construction of various rescue forces, relying on enterprises to build 102 national production safety emergency rescue teams, radiating high-risk industries such as mines, hazardous chemicals and tunnel construction throughout the country. Seven professional rescue teams have been built, and more than 2,300 social emergency teams with more than 49,000 people have been incorporated into the emergency rescue force system to standardize the development of social emergency forces. In order to meet the rescue needs of complex scenes, it is difficult to strengthen training drills, quickly strengthen strength prefabrication and strictly strengthen emergency preparedness.

Male laboratory mice exposed to mobile phone radiation are more likely to suffer from rare brain and heart tumors. This is the result of a large-scale study supported by the US government.However, don’t throw away your mobile phone yet, because the research results have caused widespread doubts in the scientific community. The risk of cancer caused by mobile phone radiation may be a common concern of "low-headed people". However, this matter is still inconclusive.

A puzzling "wonderful" discovery

The reason why this research has caused ripples inside and outside the scientific community is that there are many puzzles in the research results.

For example, the incidence of cancer in male experimental mice has increased, while that in female experimental mice has not; Compared with the experimental mice that did not receive cell phone radiation, the average life span of the experimental mice that received cell phone radiation was even longer.

This study was published by the project team of "National Toxicology Program of the United States" on the bioRxiv paper pre-publishing platform on May 26th. The National Toxicology Program of the United States is a $25 million project, which was initiated at the request of the US Food and Drug Administration (FDA), because FDA is also responsible for monitoring the radiation hazards of mobile phones.

It is worth noting that this research report is not the final result of the National Toxicology Program of the United States, because the program is expected to end in 2017. The project researchers said that the experimental data were released in advance before the experimental analysis and final report were completed because they knew that the public was very concerned about it and the experimental results were "wonderful".

Unfortunately, this study did not find a reasonable biological mechanism to explain this "wonderful" discovery. What is even more disturbing is that, like other animal experiments, the report warns that the research results obtained from rodents may be of little significance to humans.

A complex animal experiment

Undeniably, this study is indeed the most complicated experiment so far in terms of the influence of mobile phone radiation on animals.

According to official website, a magazine of Science, researchers set up 21 special rooms in Chicago, USA, to distribute the radiation from mobile phones. They divided 90 experimental mice into several groups according to sex, and then placed them in these rooms and exposed them to different intensities of mobile phone radiation for two years.

After that, the researchers examined the body of the experimental mice. They found that 2% to 3% of the male mice exposed to radiation had rare brain tumors; 2% to 6% of male experimental mice have tumors called Schwann cells in their hearts. The experimental mice that did not receive radiation did not develop tumors. There was nothing unusual in the female experimental mouse group.

In the experimental results, the data about heart tumor is the most clear, and the experimental mice receiving the most radiation have the highest proportion of this tumor. In contrast, the data related to brain tumors did not show this trend.

Although the experiment doesn’t look simple, some researchers don’t buy it. Michael Raul, deputy director of the out-of-hospital research office of the National Institutes of Health, commented that the number of animals conducting experiments was relatively small, which made people worry that the results of this study were "false positive". He said that he could not accept this conclusion.

Can the mouse experiment "translate" to people?

Up to now, the scientific community has been unable to agree on the risk of cancer caused by mobile phone radiation.

In 2011, the World Health Organization’s International Agency for Research on Cancer announced that mobile phone radiation is a "possible carcinogen". Part of the reason is that epidemiological studies on people have found that cell phone radiation is potentially related to glioma and acoustic neuroma.

However, some scientists have questioned how non-ionizing radiation generated by mobile phones can cause cancer. Because the energy of non-ionizing radiation is not enough to strip electrons from atoms, it is difficult to do harm to cells. In addition, the FDA has also stated that previous studies only found "limited evidence" that cell phone radiation increased the risk of cancer.

Although the experimental data of "National Toxicology Program of the United States" echoes the previous research results, there is another problem: to what extent can the experimental results of animals be "translated" to humans?

What is worth looking forward to is that some research teams are trying to directly study the risks of mobile phone radiation to human health. One of the studies tracked the mobile phone habits of nearly 300,000 people in five European countries, and monitored the occurrence of diseases such as cancer. However, at present, these studies have not yet yielded results.

Jonathan samit, an epidemiologist at the University of Southern California, predicts that the latest results will stimulate further research. In samit’s view, almost everyone is exposed to the radiation environment of mobile phones, so it is very important to understand it, and people should know where the "red line" of acceptable risks brought by mobile phones to human health is.

CCTV News:On August 14th, News Network reported the production and operation of small and medium-sized enterprises, the progress of green field management of autumn grain, the hot summer inbound tour, the effectiveness of Shenzhen’s foreign trade development, the effectiveness of China’s flagship species protection, and the new achievements made in finance, medical care and ecology. The quality and effectiveness of China’s development in many fields have the characteristics of "stability" and "promotion", and all walks of life have gathered energy to provide strong impetus and solid "confidence" for high-quality development.

The production and operation of small and medium-sized enterprises in China rebounded steadily in the first half of the year.

According to the data of the Ministry of Industry and Information Technology, in the first half of this year, the economic operation of China’s small and medium-sized enterprises remained stable, and the added value of industrial small and medium-sized enterprises above designated size increased by 7.4% year-on-year. Among them, the development vitality of specialized and innovative small and medium-sized enterprises continued to increase, and the electricity consumption of specialized and innovative "Little Giant" enterprises increased by 9.3% year-on-year, and the production of enterprises further picked up.

In the first half of the year, among the 31 major manufacturing industries, the total profits of small and medium-sized enterprises in 23 industries maintained growth, with an increase of 6.5 percentage points over the first quarter. The equipment manufacturing industry and consumer goods manufacturing industry increased by 5.0% and 11.4% respectively year-on-year, and the growth rate was further accelerated compared with the first quarter.

From the sales situation, the domestic and foreign trade of small and medium-sized enterprises has maintained a recovery trend. Since the beginning of this year, the export of small and medium-sized enterprises has generally maintained a prosperous state, of which the export index in the second quarter was 52.8%, accelerating the expansion of overseas markets.

The Ministry of Industry and Information Technology said that the next step will be to increase policy support in promoting the specialized and innovative development and digital transformation of small and medium-sized enterprises, cultivate a new batch of characteristic industrial clusters of small and medium-sized enterprises, build a high-quality and efficient public service system for small and medium-sized enterprises, and promote the production and operation of small and medium-sized enterprises to continue to improve steadily.

Implementing green field management of autumn grain in various places to promote stable production and income increase

At present, China’s autumn grain is at a critical stage of growth. The main producing areas vigorously promote the green production model to promote stable grain production and increase farmers’ income.

In this year’s autumn grain production, a series of green models such as fertilizer saving, water saving, medicine reduction and emission reduction have been implemented in different places according to crops and agricultural conditions.

This year, Hunan Province made an overall plan to integrate 86.3 million yuan to strengthen pest monitoring, focusing on promoting the integration of green prevention and control with unified prevention and control. At present, it is the stage of frequent pests and diseases in autumn grain. In Chunkou Town, Liuyang City, Zhu Xingren, a large grain grower, has just installed more than 1,200 sets of traps, which has enabled his more than 1,100 mu of rice to achieve full coverage of biological control.

More than 33 million mu of rice in Jiangsu Province is jointing and heading, and the continuous high temperature in recent days has brought challenges to rice growth. In Yalu Village, Taicang City, an intelligent field management system has been set up for growers. The system judges which piece of land needs how much water and how much fertilizer according to soil temperature and humidity, so that the plant protection drone can work accurately.

This year, Hebei Province has comprehensively promoted water-saving technologies such as shallow drip irrigation, drip irrigation under plastic film and integration of water and fertilizer to achieve green production. The area of high-efficiency water-saving drip irrigation in Wuyi County has increased by nearly 10,000 mu compared with last year. In the farmland of Meng Qingfu, a grower, the drip irrigation system is accurately sending water and fertilizer to the roots of corn to ensure sufficient nutrients at the booting stage of corn.

This year, Heilongjiang Province has explored the planting and breeding cycle model in 14 pilot counties (cities, districts). In the high-standard farmland in Xiangbai Manchu Township, Wangkui County, farmers are herding geese into corn fields to weed. At the same time, the excrement of geese has become a natural organic fertilizer. This year, Wangkui County has developed more than 500 farmers to increase their income through this new model of planting and breeding.

At present, there are less than 50 days before the large-scale harvest of autumn grain, and most of the autumn grain in the main producing areas is growing normally, which has a foundation for winning a bumper harvest.

Summer inbound tour is hot, foreign tourists experience Chinese charm

With the continuous expansion of China’s visa-free "circle of friends", the popularity of inbound tourism continues to rise. This summer, more and more foreign tourists come to experience China.

Tourism big data shows that this summer, China’s inbound tourism orders doubled year-on-year, and the inbound tourism orders of 14 countries including France, Italy, Germany and Thailand, which can be exempted from entry, increased by 1.5 times year-on-year. These days, in Urumqi International Bazaar, Xinjiang, although the outdoor temperature is very high, it still attracts many foreign tourists to shop and taste special food.

In addition to Urumqi, from the ancient city of Kashgar in southern Xinjiang to the mountains and grasslands in northern Xinjiang, the colorful folk culture and unique natural resources have made Xinjiang "circle" countless foreign tourists. With the implementation of the 144-hour visa-free policy for foreign tour groups from Hong Kong and Macao to enter Hainan at the end of July, Hainan’s inbound tourism market has also become more intense. At the sailing and windsurfing base in Xixiu Beach, Haikou City, a research group from Britain is learning sailing and windsurfing here.

At present, the application scope of China’s 144-hour transit visa-free policy has been extended to 37 ports and 54 countries, and a number of transit visa-free policies and customs clearance facilities have been released, making it more convenient for foreign tourists to visit China.

This summer, in addition to traditional group tours, the tendency of "individual travel" for inbound tours is more obvious, and the proportion of free travel and customized tours is gradually increasing. Not only do they punch in the traditional hot spots in Beijing, Shanghai, Guangzhou, Xi ‘an and other cities, but foreign tourists also like to take the high-speed train, and they are willing to visit small towns and enter the online celebrity vegetable market to experience China deeply and explore the more diverse beauty of China.

Shenzhen’s foreign trade has reached a new high, new and old.

Customs statistics show that in the first half of this year, Shenzhen’s import and export data reached a new high. The "old three samples" grew steadily, and the "new three samples" achieved outstanding results.

According to customs statistics, in the first half of the year, Shenzhen’s import and export amounted to 2.2 trillion yuan, up 31.7% year-on-year, accounting for 10.4% of the national total. The total export of "old three samples" such as mobile phones, computers and household appliances was 168.45 billion yuan, an increase of 18.9%; The export of new energy vehicles was 12.87 billion yuan, an increase of 51.7%; The export of photovoltaic products was 2.48 billion yuan, an increase of 81.6%.

Since the beginning of this year, under the background of the vigorous development of global generative AI, intelligent networked vehicles and other fields, Shenzhen has supported related enterprises and continuously introduced new products such as audio and video equipment and LCD flat panel display modules, which have been welcomed by overseas markets and boosted the sustained growth of Shenzhen’s foreign trade.

The strong performance of Shenzhen’s foreign trade also benefits from a solid manufacturing foundation and a sound supply chain system, which gives Shenzhen a head start in international trade.

While consolidating the traditional market, Shenzhen enterprises have stepped up efforts to explore emerging markets such as Southeast Asia and Latin America, among which imports and exports to ASEAN increased by 51.2%, and imports and exports to countries that jointly built the "Belt and Road" increased by over 40%.

China’s flagship species protection has achieved remarkable results, and the ecosystem has benefited comprehensively.

In recent years, China’s flagship species protection has achieved remarkable results, and the ecosystem has benefited comprehensively.

According to the latest monitoring of Northeast Tiger and Leopard National Park, more than 20 wild Siberian tiger cubs have been added to the park this year. As the flagship species in the northeast forest region of China, it is also the largest cat in the world. The Northeast Tiger has great strength, amazing speed and excellent hunting ability. It is a carnivore at the top of the food chain and represents the health of the ecosystem in its region.

Snow leopard is the most typical flagship species on the Qinghai-Tibet Plateau in China, and it is also a cat living at the highest altitude. It can tolerate the low temperature of MINUS 40℃, has excellent jumping ability and climbing ability, and can walk freely on almost vertical cliffs.

Since the establishment of the first national parks, the total wild population of giant pandas in China has increased from about 1,100 in the 1980s to nearly 1,900. The number of the flagship species of the Wuyishan National Park has also increased from 400 to about 700. The number of gibbons in Hainan Tropical Rainforest National Park has increased from 32 in 5 groups to 37 in 6 groups, which is the only successful case based on natural restoration among the less than 10 critically endangered species in the world. In addition to national parks, the flagship species Huabei Leopard, which appears in Shanxi, Shaanxi, Henan and other places in China, is also a vivid embodiment of the achievements of the Yellow River ecological function zone in China. While the flagship species have been well restored, their "umbrella protection effect" has also benefited the entire ecosystem of their habitat.
