CCTV News:The increase of rainfall in summer is easy to cause natural disasters. Nowadays, with the progress of science and technology, more and more monitoring equipment helps people to perceive disasters in advance, and can quickly respond to grab more time to avoid danger through early warning. Today’s "Driving Force of Science and Technology" reveals how to use the power of science and technology to early warn the occurrence of geological disasters. Let’s look at a news scene first.

Not long ago, affected by continuous rainfall, the automatic monitoring equipment for geological disasters installed in Mudong Village, Jingde Town, Debao County, Guangxi triggered an early warning, and the geological monitors in Mudong Village immediately reported the situation to the County Natural Resources Bureau. According to the urgent judgment of technicians, there is a great possibility of debris flow at this hidden danger point, and it is immediately suggested that Jingde Town Government organize the evacuation of 41 people from 15 threatened households.

Liang Rongchang, a geological monitor of Tangdongtun, Mudong Village, Debao County, Baise City, Guangxi Province, recalled: "After the evacuation, it took about 10 to 20 minutes, and the mudslides came out, and the roads in the tundra were covered."

Wang Zhi, secretary of the party branch of Naliaotun, Mudong Village, Debao County, Baise City, Guangxi Province, said: "Fortunately, there was an early warning to evacuate quickly that day, so no casualties were caused."

The mudslide caused damage to nine houses. From 19: 10 on the same day to 19: 30, the mudslide occurred. Due to the timely warning, it won valuable 20 minutes for the evacuation of the people and avoided the possible casualties of 18 people in 9 households.

Combining technology with civil air defense to avoid casualties caused by geological disasters

In addition to debris flow, landslide is also a common geological disaster. According to the statistics of the Ministry of Natural Resources, among all kinds of geological disasters, landslide disasters caused by rainfall account for about 70%. The time window from receiving early warning to disaster occurrence is usually very short. How to effectively evacuate the people in the hidden danger area in a short time and avoid casualties to the maximum extent? Let’s look at a case that happened in Yunnan not long ago.

One morning not long ago, Zhao Hai, a geological monitor in Nongbing Village, Xishan Township, mangshi, Yunnan Province, received a disaster warning of a hidden danger point in the village. He immediately investigated the hidden dangers in the village and found that there was a great possibility of disasters.

The monitor knocked on the door while knocking on the gong, and the person who received the notice quickly informed the next household to move the person to a safe place. At about 6: 20 in the morning, all the villagers evacuated safely. Twenty minutes later, the landslide happened.　

The danger is imminent. How can people who are still asleep be evacuated quickly? At this time, mangshi’s "ten-household" grid mechanism played a key role. Before the flood came, Nongbing Village organized the masses to move to avoid danger in groups of ten households according to the principle of "living adjacent to each other and easy to concentrate", and the village also conducted emergency evacuation drills in advance.

Cun Daihua, secretary of the Party Committee of Xishan Township, mangshi, Dehong Prefecture, said: "We mainly put ‘ Ten households ’ Blend in After notifying one household, everyone else will be responsible for notifying the next household, which greatly shortens the time. "

Because of proper measures, all 34 people from 17 households in the village were successfully transferred, avoiding casualties. The monitoring and early warning equipment in Nongbing Village consists of multiple instruments, and the early warning horn and mud level meter installed in the debris flow ditch form a small automatic early warning unit.

Zhao Hai, a geological monitor, said: "The four sets of equipment installed in our stockade have brought us the benefits of accurate forecasting, so that ordinary people can quickly evacuate to a safe place."

Mud level meter detects the change of river bed height and transmits data.

Affected by global climate change, in recent two years, severe weather has occurred frequently, and the prevention of geological disasters is facing greater challenges. In extreme weather, how various monitoring and early warning technologies respond quickly and grab more hedging time has attracted much attention. The mud level meter mentioned in the news just now can detect the change of river bed height and achieve the purpose of early warning, and this equipment has also been put into use in Guangxi.　

In recent years, the natural resources department of Guangxi has specially installed automatic monitoring and early warning equipment in some hidden danger points of geological disasters with serious danger. On a hillside in Mudong Village, Debao County, Baise City, an early warning equipment mud level meter is installed, which can predict the possibility of debris flow disaster in advance. The mud level meter is also connected to the emergency warning horn below the hillside to inform the villagers to evacuate in time.

Nong Youyu, director of Baise Sub-station of the Geological Environment Monitoring Station of the Department of Natural Resources, said: "The mud level meter is a set of equipment specially developed for the geological disaster of debris flow. Its main principle is to monitor whether there is siltation and accumulation in the debris flow ditch, as well as to detect the change of riverbed height. After monitoring that the rainfall is relatively large and there are some signs of deformation, the monitoring equipment on the mountain will transmit the data to us. "

An Junzhu, an engineer of the Geological Environment Monitoring Station of the Department of Natural Resources, said: "This is a geological disaster monitoring and early warning system in Guangxi. It mainly manages all 3,470 monitoring stations, and more than 22,000 monitoring equipment are all included in the system management. After the monitoring equipment in the field collects the data, it uploads it to the background server. Once this data changes beyond the preset warning threshold, the platform will generate early warning information to remind the people to evacuate urgently. "

The reporter asked: "How long does it take from discovery to system response to early warning broadcast?"

An Junzhu replied: "Generally, it is 20-mdash; 30 seconds. "

At present, China is promoting the scale and industrialization of monitoring instruments and equipment. In recent years, the automatic monitoring equipment developed has higher integration and reliability.

Zhangming, director of the Geological Disaster Technology and Method Office of China Geological Environment Monitoring Institute, said: "All the instruments we have developed at present are constantly iteratively upgraded, and the cost of comprehensive monitoring of geological hazards has dropped to about 100,000 yuan."

At present, the Ministry of Natural Resources has deployed 280,000 sets of automatic monitoring equipment nationwide, covering 59,000 geological hazards. Through scientific early warning, 68 disasters have been successfully predicted this year, avoiding 216 possible casualties.

Active prevention and control of hidden dangers of major disasters by integrating "space and heaven"

In addition to achieving the purpose of early warning through automatic early warning and monitoring equipment, in recent years, through satellite, unmanned aerial vehicle and ground investigation, China has built an integrated remote sensing monitoring technology system for hidden points of geological disasters, realizing the active prevention and control of major disasters.

Since 2020, China has completed the identification of hidden dangers in 713 counties with 4.07 million square kilometers in high-risk and prone areas of geological disasters through advanced observation methods such as radar satellites, optical satellites and aerial remote sensing, lidar and drone remote sensing.

Ge Daqing, director of the Institute of Remote Sensing Technology of China Natural Resources Aviation Geophysical Prospecting and Remote Sensing Center, said: "There are 35,890 suspected hidden dangers, and 15,000 of them have been verified on the spot. The correct rate of feedback is about 50%, and more than 4,200 of them are new and unknown in the past."

The application of satellite and aerial remote sensing is aimed at key targets.

Ge Daqing introduced: "The main focus is on some mountain and canyon areas, the threat of inaccessible people and complex ground investigation conditions, and these major hidden dangers of major facilities in villages and market towns."

Due to the complex geological structure and prone to geological disasters, there are 21,896 hidden dangers of geological disasters in Gansu Province, ranking third in the country. In Gansu Institute of Geological Environment Monitoring, technicians use radar satellites running in low-earth orbit all the time to monitor more than 20,000 hidden danger points of geological disasters in the province 24 hours a day.

Shi Pengqing, director of the Information Center of Gansu Geological Environment Monitoring Institute, said: "We first obtained the surface deformation information by using radar satellites. Like this area, we can see that it has obvious deformation areas, with purple representing obvious deformation and yellow representing slight deformation."

Radar satellites can detect deformation, while high-resolution optical satellites can determine the range of hidden dangers. The 2-meter resolution satellite of "Gaofen-1" can judge the outline of large and extra-large landslides, and the range of landslides can be determined by combining the deformation information. Gansu has also achieved full coverage of 0.8-meter resolution optical images of key cities, and its ability to identify hidden dangers has been further strengthened.

The suspected hidden danger points seen on the satellite need further confirmation on the ground. In the past, geologists had to wade across mountains and rivers, measure landslides bit by bit and monitor hidden dangers on the spot. But now, a drone can take off and land several times to complete the work of the past few days.

He Peng, a senior engineer of China Natural Resources Aviation Geophysical Prospecting and Remote Sensing Center, said: "We have done a lot of work in the early stage by means of remote sensing to avoid our personnel running around the mountains and reduce the workload, so that local experts can focus more on their goals and better realize the concept of people first and life first."

　　Zhongxin Jingwei Client September 8 (Zhao Jiaran) Recently, many consumers have found that many brands of shared charging treasures have seen price increases, and even some stores have risen to 8 yuan/hour, which surprised users.

　　In addition to sharing charging treasures, bike-sharing brands such as mobike and Little Blue Car have also increased their prices, which is quite different from the situation that they once offered various concessions and seized the market. Is the overall price increase of the sharing economy accidental or inevitable? If consumers don’t buy it, will the price increase become a wrong move?

　　"Borrowing a few charging treasures is more expensive than buying one."

　　I don’t know when it started, but the price of the shared charging treasure of "1 yuan 1 hour" has quietly increased.

　　According to consumers, the prices of some cabinets of Shundian and Monster Charging brands have risen to 2.5 yuan /30 minutes, that is, 5 yuan per hour. CCTV Finance reported that some merchants said that the current maximum charging standard for shared charging treasure has reached 8 yuan per hour, mainly concentrated in areas with large traffic and good location such as scenic spots and ports; And the cabinets priced at 1 yuan per hour are few.

　　Some consumers said it was difficult to accept the situation that the price of the shared charging treasure was greatly raised. "If the price generally rises to 5 yuan or even 8 yuan, it may cost tens of yuan to borrow it once, and it is more expensive to borrow it several times than to buy a charging treasure, which is not worth the candle." Ms. Chang, a consumer, said that she recently bought a portable charging treasure to carry with her and tried not to use the shared charging treasure.

　　Recently, the Zhongxin Jingwei client visited a number of shared charging treasure stores located in Wangfujing business district in Beijing, including street power, small power, incoming calls, monster charging and other brands. It is understood that the hourly price of most shared charging treasures is around 2-3 yuan. In addition, the use price is not marked on the shared charging treasure cabinet, and consumers can only know the charging standard of the current cabinet after scanning the code. During the dinner time when the passenger flow is relatively large, many shared charging treasure cabinets are unattended.

　　In an interview with Zhongxin Jingwei client, the related staff of Caller Technology said that the price of shared charging treasure is affected by comprehensive factors and is generally measured according to the difficulty of operation and maintenance and the cost.

　　Talking about the price increase of some stores, the staff said that the shared charging treasure is not a one-size-fits-all full-scene price increase, and there is no clear price increase round, but overall, the industry charging standard is indeed slightly higher than before. Price increases are often caused by a combination of many reasons, such as merchants asking for higher pricing to obtain higher share income, and more importantly, the continuous increase in channel operating costs.

　　"The rental fee for the shared charging treasure is still a small payment, but the mobile phone is in urgent need of power, so it is basically acceptable for users to adjust the price within a reasonable range." The above staff said.

　　Street power related staff told Zhongxin Jingwei client that at present, the hourly price of street power sharing charging treasure is mostly within 2 yuan. "At the beginning of this year, the shared charging treasure enterprise has been adjusted from 1 yuan to 2 yuan’s price system. As far as street power is concerned, the price is balanced and stable according to market conditions, and there will be no sharp increase or decline in prices in a short period of time in the future. "

　　The sharing economy era of "1 yuan 1 hour" has become a thing of the past.

　　In addition to sharing charging treasures, bike-sharing, which is in the streets, has also experienced a wave of price increases.

　　Since the first half of this year, brands such as mobike, Little Blue Car and Harrow have adjusted their charging standards in some areas. Taking Beijing as an example, the starting price of a small blue bicycle rose from 1 yuan /30 minutes to 1 yuan /15 minutes, and 0.5 yuan /15 minutes after exceeding the time limit. The starting price in mobike is adjusted to 1 yuan/15min, and the duration fee is adjusted to 0.5 yuan/15min. Hellobike’s new charging rule is also 1 yuan /15 minutes. Some netizens have calculated that riding an hour will cost 4 yuan the most, which is more than taking a bus.

　　At the same time, some consumers reported that the damage probability of bike-sharing in some areas increased instead of decreasing. Miss Li, a citizen of Beijing, said that she often encountered broken cars or bicycles with incomplete functions when commuting recently, and she was more concerned about the quality guarantee of vehicles than the price. "Now finding a car that is trouble-free and easy to ride is like finding a treasure. Sometimes you can’t ride several cars in a row, which is too time consuming. If we can deal with bad cars in time and ensure the quality, it is acceptable to increase a few dollars. "

　　In the poll "bike-sharing is more expensive than a bus, can you ride it?" sponsored by official website Weibo of Zhongxin Jingwei, netizens who chose "No" accounted for the highest proportion, accounting for 36.6%, followed by "It depends", accounting for 32.2%.

　Bike-sharing Zhongxin Jingwei Zhao Jiaran photo

　　Consumers have shown different attitudes towards the sharing of charging treasures, the price increase in bike-sharing and the status quo that the "one hour in 1 yuan" era is gone forever. In the discussion on social media, some netizens believe that enterprises need income to operate for a long time, and the price increase is understandable; Some netizens also pointed out that such shared products are not just needed, and will be replaced when the price/performance ratio is too low.

　　Jinyi should strive to be your light: I thought it was convenient and cheap before, so I didn’t worry about running out of electricity without charging treasure. Now that prices are soaring, I’d rather buy a small charging treasure. Now there are many styles of charging treasures and the price is not high.

　　Snow white: I used to rely on sharing, but now the price increase is too fierce and I can’t afford it.

　　The first impression: the price increase visible to the naked eye, many times because there is no place to return the charging treasure in the popular location, in order to find it for a long time, it costs money.

　　Fat pigeon paper Xiansen: Sharing provides speed, convenience and cheapness. Isn’t that enough? You still have to enjoy free to be happy?

　　Lv Jun byr: People are not profitable. Where can I get the money to continue to provide services for you?

　　Is the next step of price increase profitable or "cool"?

　　According to the "China Sharing Economy Development Annual Report (2019)" released by the National Information Center, the transaction scale of China’s sharing economy in 2018 was 2,942 billion yuan, an increase of 41.6% over the previous year; The number of participants in the sharing economy is about 760 million, and the number of participants in providing services is about 75 million, an increase of 7.1% year-on-year. At the same time, the scale of direct financing in the sharing economy in 2018 was about 149 billion yuan, down 23.2% year-on-year. The report pointed out that after the rapid development in previous years, the development speed of the sharing economy in the field of life services has slowed down.

　　Some insiders believe that the sharing economy is cultivating users’ consumption habits, and the price increase at this time reflects that the sharing economy is coming out of the primary stage of "price war". As for whether consumers accept the price increase, it depends on whether the service of the sharing enterprise can meet the needs of consumers. If we only keep an eye on the price increase without improving the standard of service, it may be "cool" instead.

　　Li Xiaohua, a researcher at the Institute of Industrial Economics of China Academy of Social Sciences, said in an interview with Zhongxin Jingwei that the sharing economy has entered a relatively rational and mature stage, and the industry pattern tends to be stable.

　　Regarding the current price increase trend of shared charging treasure and bike-sharing enterprises, Li Xiaohua pointed out that the price increase is an inevitable process. "At present, the price increase of merchants may also be testing the acceptance of consumers and establishing their own adjustment mechanism. If the number of users drops sharply, the merchant may adjust the price again. If the price is set too high, or a new enterprise enters the market, compete at a lower price. "

　　Li Xiaohua pointed out that the sharing economy will form a more dynamic and differentiated pricing trend in the future. "Just as the price of online car will be adjusted in real time during peak hours and holidays, bike-sharing and shared charging treasure can also determine the specific price according to the relationship between supply and demand. For example, during major festivals, the number of customers in shopping malls and restaurants has increased sharply, and the number of people using charging treasures has increased, so the real-time price of shared charging treasures can be raised accordingly; On the contrary, prices can also drop during periods of less demand such as working days.

　　Xinhua News Agency, Beijing, January 1st　Special feature: 2022, Analysis of the "change" of the global market trend

　　Xinhua news agency reporter

　　Looking back on 2021, the world economy gradually recovered from the impact of the new epidemic. Under the background that developed economies generally maintained loose monetary policies and many countries continuously introduced economic stimulus plans, the market liquidity was abundant, investors’ risk appetite was enhanced, and the prices of major assets in the international market mostly rose but fluctuated obviously.

　　Looking forward to 2022, the epidemic situation in COVID-19 may still fluctuate repeatedly, and the prospect of world economic recovery is facing great uncertainty. The epidemic situation, inflation trend, fiscal and monetary policy trend and geopolitical situation are the key variables affecting the asset prices in the international market. With the increase of market variables, the risk increases. How to arrange assets to preserve and increase their value and test the wisdom of investors.

　　Will the dollar rise again?

　　In 2021, the expected warming of the US Federal Reserve’s tightening monetary policy, the rapid recovery of the US economy, and the repeated innovations in the stock market all worked together to push the US dollar exchange rate upward. On December 31st, the US dollar index, which measures the US dollar against six major currencies, closed at 95.5916 points, up 6.2% compared with the end of 2020.

　　At present, the "hawkish" stance of the Federal Reserve has become clearer, and the uncertainty faced by global economic growth has increased under repeated epidemics. Market research institutions believe that there is still room for the US dollar exchange rate to rise in 2022 under the resonance of many factors such as the weakening of the world economic recovery and the differentiation of monetary policies in major developed economies.

　　On December 7, 2021, people were shopping in a supermarket in new york, USA. (Xinhua News Agency reporter Wang Yingshe)

　　Wells Fargo Securities Co., Ltd. issued a report saying that in view of the fact that the pace of tightening monetary policy in the United States is expected to be faster than that in most other developed economies, the agency has raised its expectation of dollar appreciation in 2022 and 2023. The Global Research Department of Bank of America predicts that the US benchmark interest rate will reach 2.5% by the beginning of 2024, while the interest rates of low-risk currencies such as euro, Japanese yen and Swiss franc are still difficult to normalize, which will support the strengthening of the US dollar.

　　Georgieva, managing director of the International Monetary Fund, said recently that the IMF is considering lowering its forecast for world economic growth in 2022 due to the global spread of the mutant Omicron strain in Covid-19. Analysts believe that the slowdown in world economic growth will reduce investment opportunities, weaken market risk appetite, and highlight the safe-haven currency attribute of the US dollar.

　　Experts pointed out that the further appreciation of the US dollar has a negative impact on global asset prices and the global economy, especially the recovery of emerging market economies.

　　Can the price of gold heat up

　　In 2021, under the background of repeated global epidemics and loose monetary policy, gold as an investment haven was not as popular as expected. On December 31st, the main contract of the New York Mercantile Exchange gold futures closed at $1,828.6 per ounce, down about 3.5% from the end of 2020.

　　For the future trend of gold prices, there are obvious differences in market views. Factors such as global monetary policy, inflation level, recovery trajectory and epidemic development will determine the trend of gold price, but these restrictive factors affect each other and have large variables, which may aggravate the fluctuation of gold price.

　　ANZ predicts that with the withdrawal of major economies from monetary easing and economic stimulus plans, the price of gold will lose some support in 2022, and the trend will be strong first and then weak, with an annual average price of around $1,725 per ounce.

　　Ivy Hambro, an executive of BlackRock, an asset management giant, believes that inflation will run through 2022. If the trend exceeds expectations, the real interest rate after the interest rate hike will not increase significantly, and may even decrease, thus further highlighting the investment value of gold.

　　The World Gold Council predicts that the gold market will remain volatile in 2022 due to the combined effects of global monetary policy and inflation trend, and periodic fluctuations may occur frequently.

　　Which stock market is better?

　　Thanks to the recovery of the world economy, the improvement of corporate profits and abundant liquidity, most of the major global stock markets rose in 2021.

　　With the support of loose monetary policy and unprecedented fiscal stimulus measures, European and American stock markets performed relatively strongly in 2021, among which the Standard & Poor’s 500 Index, Dow Jones Industrial Average and Nasdaq Composite Index in new york rose by 26.89%, 18.73% and 21.39% respectively. The Financial Times average price index of 100 stocks in London stock market rose by 14.3% for the whole year. The Nikkei stock index rose 4.9% for the whole year.

　　Under the influence of the Fed’s expectation of tightening monetary policy, some emerging market economies are facing the pressure of capital outflow, and the stock market is dragged down. In 2021, the bovis Pa Index in Sao Paulo, Brazil, fell by 11.93%, ending the upward trend for six consecutive years since 2015.

　　How will the global stock market evolve in 2022? Analysts believe that countries have different recovery paths, different policy spaces and different stock market trends. Tightening monetary environment and repeated epidemics are the main risks faced by global stock markets. Geopolitical factors such as mid-term elections in the US Congress and general elections in Brazil will also have an impact on the stock market trend.

　　Larry benedikt, the founder of the market research organization Speculator Company, predicts that the major stock indexes of the US stock market may decline to varying degrees in 2022.

　　The German Business Daily believes that the share prices of German listed companies were undervalued in 2021, and it is estimated that the DAX index of Frankfurt stock market will rise by about 12% in 2022. Ulrich Cartel, chief economist of Deka Bank, Germany, believes that if the epidemic control measures in Germany continue until the spring of 2022, it will have a great impact on the economy and the stock market may be drastically revised.

　　Ueno Gangzhi, a researcher at the Institute of Japanese Basic Studies, predicts that with the gradual recovery of Japan’s economy and the improvement of corporate performance, the Tokyo stock market will continue to rise in 2022, and the Nikkei stock index is expected to rise above 30,000 points by the end of the year.

　　Joelson Sampaio, an economist with the Vargas Foundation in Brazil, said that the Fed’s interest rate hike will make funds withdraw from emerging market countries, and the Brazilian stock market may fluctuate greatly in 2022 due to factors such as the Brazilian presidential election.

　　How high can oil prices go up?

　　Against the background of shortage caused by supply constraints and strong demand, the international crude oil price fluctuated upward in 2021. On December 31, the main contracts of the New York Mercantile Exchange light crude oil futures and London Brent crude oil futures closed at 75.21 and 77.78 US dollars respectively, rising by about 55% and 50% respectively.

　　Looking forward to 2022, although the market is bullish, the oil price trend still faces high uncertainty.

　　The Organization of Petroleum Exporting Countries (OPEC) recently released a report, maintaining the expectation that the world’s average daily oil demand will increase by 4.2 million barrels in 2022, and holding that Omicron’s influence on oil demand will be moderate and short-lived.

　　Goldman Sachs Group predicts that with the rising demand in aviation, transportation and infrastructure, oil demand will reach a new high in 2022 and 2023. Damien Courvalin, head of energy research at Goldman Sachs, believes that Omicron has limited impact on the economy, and the Brent crude oil futures price will remain at around $85 per barrel in 2022 and 2023. If the supply cannot keep up with the demand growth, the oil price may exceed $100 per barrel.

　　The US Energy Information Administration predicts that the supply growth of major oil-producing countries will exceed the global oil consumption growth in 2022, and the annual average price of Brent crude oil futures will be around $70 per barrel due to the new mutation Covid-19 disturbing the market.

　　[Report from the press conference of the State Council Office] 　

　　Guangming Daily, Beijing, July 22nd, by Guangming Daily reporter Yuan Yufei

　　On July 22nd, the State Council held a press conference on the traceability of Covid-19. Xu Nanping, Vice Minister of Science and Technology, Ceng Yixin, Deputy Director of the National Health and Wellness Commission, Wang Chen, Vice President of China Academy of Engineering, Dean of Peking Union Medical College and Director of the National Respiratory Medicine Center, Liang Wannian, Chinese leader of the China-World Health Organization joint research group on Covid-19 traceability, Yuan Zhiming, director of Wuhan National Biosafety Laboratory of Chinese Academy of Sciences and researcher of Wuhan Institute of Virology, and other authoritative experts actively responded to the hot issues of the traceability of the new coronavirus concerned by Chinese and foreign media.

　　Q: Is the report on global traceability in Covid-19 released by the World Health Organization on March 30th authoritative?

　　Ceng Yixin:The problem of virus traceability is a complex scientific problem. Since the outbreak of the epidemic, every responsible country and every responsible scientist is eager to find out the source of Covid-19. This is of great significance to prevent similar epidemics from happening again.

　　On March 30th this year, the World Health Organization officially released the joint research report "Global Traceability Research in Covid-19: Part of China" convened by WHO, and the global traceability research made a good start.

　　Governments, scientists and the media all over the world are very concerned about this report. Since its release a few months ago, more and more scientific evidence shows that this report is valuable, authoritative and can stand the test of science and history. The conclusion of the report is scientific, and the process of production always adheres to scientific principles.

　　This traceability research report is the China part of the global traceability research. The expert group draws the following conclusions: Coronavirus, which is closely related to Covid-19, has the highest homology with Covid-19 in terms of sequence, but these viruses are still not enough to prove that they are the direct ancestors of Covid-19, and there is still a certain gap. Combined with the research results of clinical epidemiology, animal and environmental detection, the joint expert group finally determined several possibilities for the virus to appear: the first one is "possible to relatively possible", and zoonosis directly overflows, that is, it directly overflows from animal hosts to people. The second is "more likely to be very likely", which is introduced through an intermediate host. Generally speaking, the natural host of the virus is an animal, and then it transits to people through the intermediate host. The third is "possibility", which is introduced through the cold chain. In some sporadic epidemics in various places last year, it was found that cold chain transmission may introduce viruses. The last one is the introduction of "extremely unlikely" in the laboratory.

　　In the next stage, the traceability work should be carried out under the overall coordination of WHO, and on the basis of the first stage of research, excellent experts from many countries should be organized to carry out in-depth work, scientists should be the mainstay, exchanges and cooperation should be strengthened, and the traceability work in Covid-19 should be carried out on a scientific track.

　　Q: Is Covid-19 naturally produced or caused by human factors?

　　Ceng Yixin:I really want to talk about my views on the second phase of the virus traceability plan released by WHO on July 15th. To tell you the truth, I was very surprised. Because in this plan, the hypothesis that "China violated laboratory regulations and caused virus leakage" is one of the research focuses. From this point, I can feel the disrespect for common sense and arrogant attitude towards science revealed in this plan. It is impossible for us to accept such a traceability plan.

　　What is the purpose of traceability? It is to find out the source of the virus and then take effective measures to prevent similar epidemics from happening again. Therefore, we must promote this work in accordance with scientific principles and rules. This is the attitude of the China Municipal Government.

　　So far, none of the staff and graduate students of Wuhan Institute of Virology has been infected with COVID-19. Wuhan Institute of Virology has not carried out research on the gain function of coronavirus, and there is no so-called artificial virus. So where did the virus leak due to violation of laboratory regulations come from? Therefore, this formulation violates both common sense and scientific laws. More importantly, the WHO expert group personally visited Wuhan Virus Institute, and reached the conclusion that the virus is extremely unlikely to be leaked from the laboratory. They are all very authoritative and experienced experts in various fields carefully selected by WHO. So we should respect their conclusions.

　　Yuan Zhiming:The Wuhan Institute of Virology has repeatedly responded to the rumors about the leakage of virus laboratories. Covid-19 originated from nature, which has become a general consensus in academic circles. I want to emphasize that before December 30, 2019, Wuhan Institute of Virology had not contacted, preserved or studied Covid-19. Wuhan Virus Research Institute has never designed, manufactured or leaked Covid-19.

　　Facing the sudden outbreak of COVID-19, Wuhan Institute of Virology quickly identified novel coronavirus with the advantages of platform, technology and talents accumulated for a long time, isolated the virus strain, determined the whole genome sequence, and submitted the whole genome sequence to the United Nations World Health Organization on January 12, 2020. These important research results have provided a foundation for the global antiviral drug screening and vaccine research, and also won time for the global fight against the epidemic.

　　Q: Is the original data of early communication in Wuhan public?

　　Yuan Zhiming:The structure and content of the database of Wuhan Institute of Virology are still in the process of continuous improvement. At present, the database is shared within Wuhan Institute of Virology. After analyzing and systematically sorting out some original data in the database, the staff will publish the research results in the form of papers, and display and retrieve them in the database in a visual way. After analyzing and sorting out the original data of scientific research, it will be published in the form of papers, and then the database will be made public. This is the practice of scientific and technological circles, and the Institute of Virology will strictly follow the rules of scientific and technological circles to display and share our scientific data.

　　Wuhan Institute of Virology has always insisted on the timely sharing of scientific research information, and we released the whole genome sequence to the World Health Organization in time. As early as February 3, 2020, Shi Zhengli’s research team published a research paper in Nature, proposing that Covid-19 came from nature. After we found that several drugs have antiviral activity at the cellular level, we published the research results in international magazines on February 4. At the same time, Wuhan Virus Research Institute also actively participated in the international video and audio conference held by the World Health Organization, and timely shared our research results in animal model establishment, antiviral drug screening, inactivated vaccine development in COVID-19, etc.

　　Q: What do you think about the possibility of virus spread caused by trade in cold chain products?

　　Wang Chen:The role of cold chain in the spread of infectious diseases is a new phenomenon. From Beijing Xinfadi epidemic situation and Qingdao epidemic situation, we can see such a close relationship, that is, the patients have been exposed to the cold chain, and no other possible virus sources have been found outside the cold chain.

　　In the detection of virus nucleic acid, cold chain goods nucleic acid detection is positive. Especially in the Qingdao epidemic, not only the virus nucleic acid positive was detected on the surface of cold chain items, but also the virus was isolated and cultured, which confirmed that there was a live virus on the surface of cold chain items. Combining these two points, the chain of evidence is gradually complete.

　　In the process of further virus traceability, we especially suggest that the cold chain should be regarded as a key traceability clue. At present, under the background of international trade, people and goods exchange frequently all over the world, and people in the cold chain environment — The spread of things has increased the complexity, which is particularly worthy of investigation and research.

　　Guangming Daily (July 23, 2021, 09 edition)

　　Science and Technology Daily, Beijing, October 17 (Reporter Gu Gang) Many mammals spend the cold season by hibernating. The lower the body temperature of hibernating animals, the more energy consumption can be reduced. But this is not all good. A recent study by the Veterinary University in Vienna, Austria, found that lower temperature tends to increase telomere contraction, which may accelerate cell death. To avoid this result, animals need to consume a lot of energy to repair cells.

　　Researchers have found that during hibernation, mammals with lower body temperature can reduce their physical exertion by more than 90%. In the absence of food, reducing energy consumption is very beneficial to the survival of animals. However, animal hibernation at low temperature can cause problems such as telomere contraction. In the experiment of forest Dormouse and garden Dormouse, it was found that Dormouse wintering at higher body temperature has longer telomeres, but it also consumes more energy. Researcher Julia Novak explained: "This seems to be a compromise between maintaining complete telomeres and cell survival, and minimizing energy consumption by hibernating at low body temperature."

　　The researchers also found that there are significant differences in telomere shortening between forest Dormouse and garden Dormouse when they hibernate at different temperatures. They were put into hibernation at 3℃ and 14℃ respectively in the laboratory. Dormouse consumes more energy at 14℃ than at 3℃, while chromosome telomeres are much better at 14℃. This new understanding supports the widely accepted hypothesis that hibernation also has a price.

　　Novak believes: "Deep hibernation is related to the cost at the cellular level, that is to say, the recovery of telomere length after shortening must be at the expense of animal physical consumption. Previous scientific assumptions may overestimate the benefits of deep hibernation in animals that can reduce physical exertion. "

　　Although hibernation has many advantages, the research also found that it has related problems. Due to the decline of immune function, slow response and increased oxidative stress, frequent awakening of animals from hibernation will also lead to a rapid reduction of energy reserves, and the up-regulation of metabolism is related to the production of reactive oxygen compounds, which will lead to a faster shortening of telomeres.

　　The length of telomeres is usually used as a sign of aging, which shortens after each somatic cell division. If its length cannot be recovered, the cell will eventually die. During hibernation, telomere recovery is destroyed.

　　This study is also of great significance to human medicine. Studies have shown that chronic human stress will accelerate telomere shortening. On the contrary, lifestyle changes will slow down telomere shortening, which will have a positive impact on the aging process of cells and the whole organism.

Wen Yi Shi Qi

Editors’ entertainment circle is full of life.

Esther Yu, a "daughter of 40 billion yuan", will go home and inherit the family property if she doesn’t become popular before the age of 28?

Others have "princess disease", and she really has "princess life".

As early as "Youth has You 2", Esther Yu’s identity was questioned by netizens.

It is reported that her limited edition bag on the stage of "Youth has You 2" is as high as 220,000.

Only a few are issued in the world, and its preciousness can be imagined.

With a limited amount that money can’t buy, she can easily get into the upper body and simply interpret "Hao" to the extreme.

In real life, Esther Yu’s luxury is not restrained at all.

Any watch is hundreds of thousands, and all kinds of limited customization models are overwhelmed.

This is not the most ridiculous.

She was in the variety show "Grade One", and everyone else was dressed as a student, only he picked up the limousine.

In the later photos of life, I also filled the whole bed with limited bags.

Who doesn’t say a word of envy after reading this, but how can only a bag be enough?

On the talent show, Esther Yu once revealed that he had brought 109 sets of clothes for the show.

Not only is there a large number, but there are countless high-definition dresses.

The first set of clothes that appeared in the draft was a well-known brand dress with a limited edition of two pieces in the world, and the price was as high as 170,000.

Can be Esther Yu easily wear in the body, her strength to be reckoned with.

So what can she rely on?

Is it by parents’ "property"?

It is rumored that her father is an aviation director and her grandfather is a major figure in the steel company.

There are countless industries in the family.

Before Esther Yu was born, his fortune had reached tens of billions.

It is rumored that her school is also a famous private school.

Tuition alone is as high as hundreds of thousands every year!

Esther Yu, who is in his early twenties, has five companies.

The starting point is the end point that ordinary people can’t reach in their lifetime.

Can the entertainment industry only rely on "money"?

Netizens found Esther Yu’s figure as early as Wang Sicong’s photo.

It is reported that Wang Sicong and I spent more than 200,000 a night in a nightclub.

In fact, it is the money they buy a watch.

It can be seen that the network resources are first-class.

With the support of family property and wide connections, you don’t walk sideways in the entertainment circle?

If she can, why should she suffer this?

Early Esther Yu, like other young actors, was a walk-on.

At the age of 20 in 2015, she took her suitcase alone and went to the desert to film.

No assistant, no company.

What a good role I thought it was, but it turned out to be female number n.

Several subsequent dramas were filmed, all of which were tepid.

The family also gave Esther Yu an ultimatum: "No more, come back to do business".

But she was still unwilling, so she took part in Youth with You 2.

Become famous in World War I.

What she is really angry about is an expression pack.

A "wow doll" succeeded in making netizens notice this little girl with a perverse personality.

At the same time, her opportunity also followed.

A director saw her grandiose expression and unique voice.

Invite her to voice Polly Ma.

This is also her first step towards the entertainment circle.

Father really can’t stand her situation.

I used the "money ability" to pave the way for her.

Also successfully let her shoot "My Wonderful Boyfriend 2".

If you mean other stars, you must avoid them.

But Esther Yu said it generously in the interview, and did not intend to hide it.

It was also suspected by netizens that Wu Qian was squeezed out to get this role.

But she doesn’t seem to mind at all.

After that, Esther Yu seems to have completely "upgraded her coffee".

In The Little Forest for Two, her acting skills slowly changed.

But it seems that the fire has not completely exploded at this time.

Cai Minmin in "The Next Stop of Happiness" can be said to be Esther Yu himself.

Her performance in this play can be said to have surpassed that of Victoria Song, the leading actress.

One has a supporting role, and her acting skills have finally been experienced.

I also had the opportunity to carry the banner alone.

In 2022, a drama of god was born, "Cang Lan Ji".

It is also this drama that makes Esther Yu really popular all over the network.

"Little Orchid" was thoroughly performed by her.

She can finally say that she relies on strength, not "money".

At the beginning of the filming of Freesia, the director said that dubbing was needed.

Esther Yu insisted on using the original sound after hearing it.

However, the director replied, "Your voice is so bad, how to use it"?

She went to learn dubbing silently for a month and finally succeeded in persuading the director to use the original sound.

The final result also proves that her efforts have not been in vain!

In 2022, she succeeded because the play was nominated for the most popular actress of the year.

Although he didn’t win the prize in the end, this award was a qualitative leap for him.

Even the seniors in the entertainment circle praised her: I feel that she is laughing and laughing, but in fact she has made all the preparations behind her back.

It is her sincerity and hard work that have made today’s achievements.

Recently, Guo Xiaosi’s "Feather of the Cloud" suddenly airborne.

Under the controversy, netizens also saw the strength of Esther Yu.

Esther Yu was finally recognized by netizens.

The broadcast volume of "Cloud Feather" is the first on the hot list!

While admiring her acting skills, everyone found that she seemed different from what she had seen before.

Did she secretly go for plastic surgery to look good on camera?

In fact, it is the credit of director Guo Xiaosi, and Esther Yu said that he was "cheated".

The director fooled her: "Don’t you want to make a good-looking play at the most beautiful and youngest time?"?

After hearing this reason, she immediately made up her mind to lose weight and study, so today’s "Cloud Feather" came into being.

Conclusion:

As a "rich second generation" and a "pampered princess" in the entertainment circle, Esther Yu didn’t give up because of setbacks.

It is her spirit of not giving up on her goals that makes her present position in the entertainment circle.

So do you like Esther Yu?

　　On-the-spot analysts pointed out that QQ music keeps up with the trend of the mobile digital era. It has invested heavily in software development and copyright purchase, but it has been in a downturn in the paid music market, mainly due to the bottleneck of the hardware of digital audio playback carrier in audio technology. The release of digital audio solution has solved this problem.

Yunnan’s vegetable and fruit agricultural and sideline products are facing unsalable sales Viya helps farmers live broadcast activities

The fourth season of "Yearning for Life" continued to carry out the "helping farmers and helping farmers" public welfare activities to the end. During the recording, the guest members and program team of Mushroom House learned that the suspension of the opening of tourist attractions and dining venues has caused the fruits and related agricultural and sideline products originally grown during the peak tourism period to face slow sales, and the previous investment will also be wasted. Adhering to the tenet of "helping farmers and helping farmers" since the four seasons, the program team and guests quickly formulated a assistance plan and invited the famous live streaming host Viya to help farmers solve practical problems through live online sales. This move has also received strong support from the local government. Under the coordination and preparation of various parties, the live broadcast was officially launched at 21:00 on April 15. The 1-hour live broadcast event harvested more than 19.45 million online viewers, and sold a total of 195,759 agricultural products. The sales reached 5246,682.35 yuan, which will effectively benefit 1,750 villagers in 195 villages in Xishuangbanna.
