Interstellar visitors invade the solar system: does life on earth come from another galaxy?

  Today viewpoint

  In the autumn of 2017, the cigar-shaped Oumuamua broke into the solar system and became the first interstellar visitor discovered and confirmed by scientists, which caused a lot of noise and turmoil in the scientific community. Although it is still unknown whether it is an asteroid, a comet or an alien spacecraft, American scientists have recently said that "flying immortals from outer space" like Omo Mo may not be special, and the elements of life on earth may originate from other star systems, which arrived on Earth by hitchhiking with interstellar visitors like Omo Mo Mo.

  But at present, these are only assumptions. We need to "catch" more celestial bodies similar to Omo Mo for in-depth research with the help of large telescopes in the future to get the final answer.

  "Omo Mo" is not special

  The researchers said that "Omo Mo" is the first confirmed interstellar object we have observed in the solar system, but this does not mean that it is the first interstellar object to reach the solar system in history.

  "We think, like ‘ Omo Mo ’ Such an object … … At any time, there will be one at a distance of one astronomical unit from the sun (the average distance between the earth and the sun is about 150 million kilometers). " At the "Breakthrough Discuss" conference held at the University of California, Berkeley last month, Bill Porter, head of the Department of Space Studies at the Southwest Research Institute in Colorado, said, "This actually has a very meaningful impact, similar to ‘ Omo Mo ’ Objects may bring life from one celestial body to another. "

  This idea is called "panspermia)— — The theory put forward by scientists in the 1970s that life on earth came from space. At that time, the British physicist Lord kelvin believed that alien bacteria could reach the earth by comet or meteor and thrive on the earth; Other scientists believe that microorganisms can be embedded in dust particles and pass through galaxies, and they run from one planetary system to another through slight stellar radiation pressure.

  Can provide heat insulation and radiation protection for microorganisms.

  At present, the exact size of Omo Momo is still unknown, but researchers believe that its longest size is no more than 800 meters. The object will show "non-gravitational acceleration" when it is far away from the sun, which makes people speculate that "Omo Mo" may be some kind of alien spacecraft.

  But the more common view is that the "intruder" of this solar system is very cold, and its strange movement is caused by the exhaust gas similar to a comet. When the comet approaches the sun, the ice on it will sublimate directly from solid to gas, forming a huge comet head and a long comet tail. When these gases are released, astronomers can use telescopes to study and determine their composition.

  Karen Mitch, an astrobiologist at the Institute of Astronomy, University of Hawaii, said: "This tells us that ice can be preserved after such a long journey." Previous studies on comets and other small celestial bodies in our solar system show that objects like Omo have good heat insulation and radiation protection functions, which is good news for any microorganism that may "hitchhike". "Living organic matter can be found in ‘ Omo Mo ’ The interior is well protected. "

  Astronomers have not found the star system that gave birth to Omo, so we don’t know how long ago Omo was ejected into the dark and cold interstellar dust. But Mickey said that it may have traveled through interstellar space for 10 million years or more.

  Looking for the next interstellar object to study.

  Of course, it is still unclear whether any hypothetical creature on Omo will survive the collision with the earth. Mickey said that this icy object hit us at a speed of 215,000 km/h relative to our planet. "This is a very high impact speed."

  In this regard, Stern Sigurdsson, a professor in the Department of Astronomy and Astrophysics at Pennsylvania State University, said in another speech at the "Breakthrough Discussion" conference that "Omo Mo" and its "passengers" may be quite soft, so after hitting the earth, they may land relatively gently and disperse when they break into our atmosphere.

  Sigurdsson said that the previous work of Ivey Laueber, director of the astronomy department of Harvard University, and others, as well as his own calculations show that in the nearly 4.6 billion years of history of our planet, about 100 celestial bodies like Omo have hit the earth. "So, we don’t know whether there is a biota inside one of these celestial bodies."

  Laueber added that we don’t know where Omo is now. "Therefore, it is more meaningful to find the next interstellar object." The powerful large-scale weather measuring telescope (SST) is scheduled to take off from Chile next year and begin to observe the sky. When it runs "full of blood", it may find an interstellar object every month for our study.

  In addition, scientists suggest that it is also possible that life reached the earth only a short distance long ago. Earthlike planets in our solar system exchange rocks quite regularly, as evidenced by the increasing number of Martian meteorites on earth. In fact, some researchers believe that life on earth may have started on the red planet, and a Martian stone reached the earth in a strong impact.

  Of course, all this is just a hypothesis, and more scientific evidence is needed to reveal one of the ultimate puzzles of mankind — — Where we come from.

More than 10 tons of chemically synthesized fake jellyfish silk entering the market is harmful to long-term consumption.

  In fact, this "artificial jellyfish silk" is not a seafood at all. Its raw materials are three food additives: sodium alginate, ammonium aluminum sulfate (commonly known as alum) and anhydrous calcium chloride.

  Jellyfish silk has also been faked! Yesterday, the media in Hangzhou revealed that Huzhou police seized a large number of fake jellyfish silk in the local farmers’ market according to the report, and then traced it to a ton of fake jellyfish silk. The so-called "jellyfish silk" was all artificially synthesized with chemical raw materials. And the source of this fake jellyfish silk is actually in Changzhou.

  The Yangzi Evening News reporter contacted Changzhou police to confirm that it was true. An Anhui couple hired a coolie in Changzhou and rented a private house in Zouqu, Changzhou as a small workshop to produce and process this fake jellyfish silk.

  Yangzi Evening News All-Media Reporter Zhang Bin

  False jellyfish silk exposure

  After the information of "Fake jellyfish silk" is released, frightened friends may need a dish of real jellyfish silk to suppress the shock, so it is necessary to popularize science here — —

  How to tell true from false jellyfish silk?

  false

  Jellyfish silk:

  It’s transparent, tasteless and tough, and it’s not easy to break by pulling it gently with your hands. If you take it out of the water and put it for a while, it will be as soft as scotch tape.

  real

  Jellyfish silk:

  It looks white and yellow, and smells fishy. High-quality jellyfish silk is white or light yellow, with color and no erythema and sediment. Spread out jellyfish silk, the bigger, the whiter and the thinner the better. The meat is crisp, not hard, not broken, crunchy and chewy.

  The case is full of ups and downs

  Media exposure:

  Huzhou seized "artificial jellyfish silk"

  The suspect confessed that he was learning from Changzhou’s "master".

  On May 7th, Hangzhou media published a case that Huzhou police cracked the sale of fake jellyfish silk.

  According to the media report, "three suspects, including Yuan Mou, illegally produced and sold fake jellyfish in the farmer’s market in Shangcheng Road, Zhili Town, Huzhou for almost a year!" In late April this year, the Food and Drug Ring Detachment of Huzhou Public Security Bureau received such a report. Huzhou police immediately joined forces with the Market Supervision Bureau to enforce the law. On April 22nd, they seized more than 300 kilograms of "artificial jellyfish silk" on the spot.

  After investigation, since June, 2015, Yuan and others, knowing that the artificial jellyfish silk did not meet the food safety standards, still used sodium alginate, anhydrous calcium chloride, ammonium aluminum sulfate and other raw materials to make artificial jellyfish silk, and sold it in the frozen food store operated by Shangcheng Road Farmers’ Market in Zhili Town, making an illegal profit of more than 70,000 yuan.

  According to Yuan, he also knows that this fake jellyfish silk is harmful, but the wholesale price of jellyfish in the past two years is generally 30-50 kg, and the breeding period is about 40 days. The cost of fake jellyfish is nearly half lower than that of cultured jellyfish, and it sells well and the production cycle is not long, so they will take risks for almost a year.

  He also said that his craft was learned from the "master" in Changzhou, and the raw materials were also imported from the "master".

  Therefore, Huzhou police rushed to Changzhou, and on the afternoon of April 29, they arrested Jia, the "master" Yuan said, and his accomplices Sun and Ma. And seized 1 ton of finished and semi-finished products of "artificial jellyfish silk" at the scene! After investigation, Jia and other three people have produced more than 10 tons of fake jellyfish in the past year, making an illegal profit of more than 100,000 yuan.

  Jia confessed that people from many places came here to study art and purchase goods.

  Reporter connection:

  Changzhou police cooperate with "one pot end"

  The "counterfeiting den" is located in a private house in Zou District, Changzhou.

  Yesterday afternoon, the reporter contacted Changzhou police to confirm that it did happen. According to Changzhou police, Huzhou police, together with law enforcement officers from the local market supervision department, came to Changzhou. After knowing the specific location of the fake dens, they asked Changzhou police to cooperate with them to arrest the suspects.

  "Food cases are no small matter!" After receiving the instruction, the Public Security Bureau of Zhonglou attached great importance to it, and immediately arranged nearly 20 police officers to cooperate with the arrest. Everyone Qi Xin worked together to arrest the suspects Jia Mou, Sun Mou and Ma Mou in a private house in Qianjia Village, Zouqu Village Committee, Zouqu Town, Zhonglou District.

  A police officer involved in the arrest told reporters that they were also surprised when they saw the scene! Houses have become private workshops filled with plastic buckets of all sizes. Three people are producing and processing "fake jellyfish silk" in the workshop. Law enforcement officers in Huzhou seized a large number of raw materials and "fake jellyfish silk" at the scene. Later, I called a truck to drag these fake tools and products back to Huzhou.

  According to Changzhou police, the trial of the case, taking photos on the spot and obtaining evidence were all conducted by Huzhou police and law enforcement officers of the local market supervision department. Changzhou police mainly cooperate with the arrest work and are not very clear about the specific circumstances of the case. However, Changzhou police learned that the three suspects were all from Anhui, two of them were husband and wife, and the other was a coolie hired by the husband and wife. The couple are doing business in Changzhou, but the Huzhou police are still investigating where the "fake jellyfish silk" flows.

  Changzhou police said that there may be some action in the later stage of the case, and Changzhou police will pay close attention to the case dynamics.

  Fake jellyfish silk is very harmful.

  Long-term consumption will lead to malnutrition, neurasthenia, and even stupidity.

  Long-term consumption of "artificial jellyfish silk" is extremely harmful. Sodium alginate is a good thickener and a safe food additive in "artificial jellyfish silk". However, additives are additives after all, and it is somewhat inappropriate to eat additives as food. The reporter checked the relevant information and found that sodium alginate contains more cellulose. Although cellulose has certain benefits to the human body, eating too much will affect the absorption of nutrients. It will also adsorb minerals such as iron, calcium, magnesium and zinc existing in other foods in the intestines, so that these nutrients can not be absorbed by the human body, so eating more can cause malnutrition and other symptoms due to lack of various minerals.

  In addition, another raw material in "artificial jellyfish silk" is alum. This material has a high content of aluminum, which will affect the absorption of calcium, iron and other minerals by the human body for a long time, leading to osteoporosis, anemia and so on. In addition, long-term intake of aluminum can affect or even destroy the human nervous system, which significantly increases the incidence of neurasthenia and even makes people susceptible to Alzheimer’s disease, that is, senile dementia. After testing, the aluminum content in the "artificial jellyfish silk" made by Jia and others exceeded the standard seriously, reaching 600-800mg. Long-term consumption is extremely harmful.

Mengzhou, Henan Province: Smart Agriculture Broadens the Way to Increase Income

  Chen Xinfeng, the person in charge of the ecological park, and the staff are carrying out professional leaf splitting, flower thinning and fruit thinning on the elevated strawberries to ensure the quality after listing. This is the second year that he has cultivated strawberries without soil. Compared with the traditional cultivation of strawberries, this cultivation technology has a better planting environment and greatly improved the picking experience of tourists. 

  

Tourists pick and punch cards in the high-ridge strawberry greenhouse. 

  "Our main varieties are ice cream strawberries, chocolate strawberries and cream strawberries. The output of each greenhouse is about 4,000 kilograms, and each kilogram can be sold to 45 yuan. From now until June, it is the peak season for picking, and the total income is expected to reach 300,000 yuan." Chen Xinfeng told reporters that the strawberries he planted were well received by the market. In addition to supplying local supermarkets, many customers in Zhengzhou and Luoyang booked them, which was in short supply. 

The person in charge introduced the situation of soilless cultivation of strawberries for tourists who came to pick them. 

  Inspired by "elevated" strawberries, in 2024, Chen Xinfeng transformed the strawberry greenhouse into a smart agricultural greenhouse to plant "high-ridge" strawberries to improve quality and yield. In the transformation, he raised the ridge by 30 cm with steel frame, which is more suitable for the development of sightseeing and picking agriculture; Adopt intelligent drip irrigation and water circulation heating technology system to accurately control air humidity and nutrient supply, and ensure stable growth environment while saving water and fertilizer; Using physical pest control and biological control technology to replace traditional pesticides to ensure that strawberries are green and pollution-free; Equipped with automatic temperature control and light supplement equipment, so that strawberry growth is not limited by natural conditions; Pure water irrigation is used to provide high-quality and stable water source for strawberry growth and accurately meet water demand. At the same time, he also introduced the drone pollination technology of "low temperature tolerance, no flight and no shed collision", which not only improved the fruit setting rate of strawberries, but also improved the fruit quality, making the fruit shape correct and the taste sweet. 

  Walking into the meat rabbit breeding base in Hanxi Village, Dading Street, rows of modern breeding cages are uniform, and fat meat rabbits are eating and drinking leisurely. The head of the base, Mao Xing, observed the growth of rabbits and carefully recorded them. "At present, there are 144 groups of modern breeding cages in our base, with a total of more than 3,400 meat rabbits, with an annual slaughter of more than 60,000, which can generate income of 500,000 yuan." Mao Xing happily talked to the reporter about the "rabbit breeding". 

Technicians check the growth of meat rabbits. 

  There are only three or four workers in the clean and tidy breeding shed, thanks to the automatic breeding equipment introduced by the base. Automatic temperature control technology can adjust the temperature of the breeding shed in time, which is more suitable for the growth of meat rabbits; Set the feeding time on the computer, automatically start the feeding function at the point of arrival, and automatically cut off the power after feeding, feeding 1-6 times a day, which better caters to the physiological characteristics of rabbits with less food and more meals; The automatic excrement cleaning system can automatically clean excrement, reduce ammonia smell and flies and mosquitoes, reduce the disease probability and mortality of meat rabbits, and improve the survival rate of young rabbits. In addition, the rabbit manure is also used as agricultural fertilizer and exported to Fujian and Shaanxi, which increases the economic benefits. 

  "This meat rabbit breeding project can also increase the income of the village collective by 100,000 yuan every year. In the next step, the two village committees will encourage interested people to learn rabbit breeding technology, so that meat rabbit breeding will become a characteristic industry in the village and a project to increase people’s income." Yao Jialian, secretary of the village party branch, introduced. 

  The industry is prosperous, the countryside is strong and the villagers are rich. In recent years, mengzhou city has continuously intensified the adjustment of agricultural industrial structure. By increasing the popularization and application of intelligent agricultural technologies such as drones, Internet of Things and big data in agricultural production, it has changed the extensive production management mode of traditional agriculture, improved agricultural production efficiency, improved the output and quality of agricultural products, and promoted the sustainable development of agriculture. 

  It is reported that in the next step, mengzhou city will promote agricultural modernization and intelligence by cultivating high-quality agricultural skilled talents in the new era, accelerating the application of smart agricultural technology, strengthening the guarantee of data elements, and strengthening the construction of talent teams, empowering the masses with smart agriculture, helping the rural areas to fully revitalize, and painting a new picture of a beautiful countryside with strong agriculture, beautiful countryside and rich farmers.

Looking back at the military parades in New China from multiple perspectives, we can see that the army is revolutionizing, modernizing and regularizing.

The military parade is an extremely grand military ceremony.

It embodies the national prestige of a country, the military prestige of an army and the integrity of a nation.

It is an important form for soldiers to swear loyalty to the country and show their military style.

It is of great significance for promoting national prestige and military prestige, inspiring national spirit and inspiring patriotic enthusiasm.

Since the founding of New China, there have been 14 National Day military parades and the Victory Day of the Anti-Japanese War in 2015, and military parades have also been held in some large-scale military exercises.

There are many perspectives on how to look at these military parades.

You can see it from the reading formation

You can see from the weapons and equipment

From the clothing of the troops being read

You can see from the slogan of the military parade.

You can also look at it from the leader’s review car and so on

In short, the National Day military parade has a lot to watch.

From these perspectives, we can see that the achievements of national defense modernization and the revolutionary, modernized and regularized new features of the People’s Liberation Army reflect the comprehensive quality and economic strength of the country, as well as the military and cultural level of the country and the army.

"CNR National Defense Time and Space" specially invited Jiang Tingyu, former director and researcher of the Editorial Research Department of China People’s Revolutionary Military Museum, to tell you about it.

The formation of military parade is an important content and element of military parade. The formations read can reflect the development process of the People’s Liberation Army (PLA) from a single army to a synthetic army of various military types, the reform and changes of the PLA establishment system, and the achievements of the national defense and army building in new China and the brand-new features of the PLA’s revolutionary, modern and regular construction.

The troops being read are mainly the army.

In the founding ceremony military parade in 1949, 16,400 troops were read, which were formed in the sequence of the navy, army and air force.

Bitcoin broke the record high of 8,000 yuan, and the British media reported that its value was zero.

  Bitcoin’s "madness" in this round has been somewhat lasting.

  On January 5, according to the data of Huobi.com, a domestic bitcoin trading platform, at 1: 10 am, the price of bitcoin broke through the historical high of 8,000 yuan three years ago, setting a historical record. As of 8: 45 on January 5, the highest price of bitcoin reached 8650 yuan, and the price increased by more than 260% within one year.

  The British "Guardian" said that market analysts believe that the main driving force for this round of bitcoin price surge is in China — — In 2016, the RMB depreciated by nearly 7%, the worst performance in 20 years, which triggered a huge demand for Bitcoin.

  The historical highest price of Bitcoin was 8,000 yuan on November 19th, 2013. A month ago, the price of Bitcoin was still hovering around 1000 yuan, and it tripled in a short time. However, this price fell after less than 1 minute, and then it bottomed out all the way, reaching a minimum of 933 yuan.

  Compared with that rise, Bitcoin rose slightly steadily this time, from 2,351 yuan in early 2016 to 8,000 yuan in early 2017.

  Zhu Jiawei, COO of Huobi.com, said that this round of 8,000 yuan market is very different from that in 2013: First of all, the current bitcoin transaction volume is not the same as that of that year. When the highest price of Huobi was 8,000 yuan in 2013, the weekly transaction volume was 393,000 bitcoins, with a weekly amplitude of 103%, which was very small and was greatly affected by funds; Now, when the price of bitcoin breaks 8,000 yuan, the transaction volume in the four days after Huobi Net Festival is 7.35 million bitcoins, which is 37 times of that year’s transaction volume. The price amplitude in the four days after New Year’s Day in 2017 is 15.95%, which is much more stable than that year.

  In addition, Zhu Jiawei believes that after the application of Bitcoin is promoted, the price tends to be stable. Although Bitcoin rose by 260% from 2016 to 2017, it won the top spot among many investment varieties. However, in the whole year of 2016, according to the data of Huobi. com, the daily price of Bitcoin rose and fell by 10% or more in less than five days, while in 2013, the daily price rose and fell by about 10%.

  For Bitcoin entering the bull market in the past year, Zhu Jiawei analyzed the reasons: First, the underlying technology blockchain of Bitcoin has been recognized by major banks and financial institutions around the world; Secondly, in early 2016, the central bank held a digital currency seminar to start studying digital currency and blockchain technology; This year, domestic mainstream investment products, including stock market, property market, gold, etc., performed poorly on the whole, while bitcoin rose very well, and funds turned to bitcoin investment channels; Bitcoin halved its output for the second time in July 2016, which also promoted market sentiment fluctuations and pushed up prices.

  Xu Mingxing, founder and CEO of OKCoin, another bitcoin trading platform in China, analyzed this wave of gains: "According to the laws of the trading market, investment products will rise if they follow a long decline, and will fall if they rise for a long time. Judging from the cycle of Bitcoin, this price increase is a long-term cumulative result after the price peak in 2013. But it is investors’ confidence in Bitcoin that affects the price of Bitcoin for a long time. "

  The US "Wall Street Journal" reported in May last year that some analysts said that the rise of Bitcoin was mainly driven by the demand in China market brought about by the recent RMB depreciation, and the two major bitcoin trading platforms in China — — Huobi and OKCoin— — At present, it constitutes about 92% of the total global bitcoin transactions.

  Just as the speculators were ecstatic, the Financial Times "poured a pot of cold water", saying that the value of Bitcoin was zero.

  "A trading intermediary is always ups and downs, then it is a useless currency. In fact, Bitcoin has all the characteristics of pyramid scams. It requires that believers continue to enter the market to push up prices, and this is based on the promise that more believers will join in the future, so the value of Bitcoin will be the same as that of all pyramid scams. Zero. " The Financial Times reported on January 4th that.

  In China, bitcoin as a currency has never been recognized by the regulatory authorities. Five ministries and commissions, including the central bank, said in the Notice on Preventing Bitcoin Risks issued in December 2013 that although Bitcoin is called "currency", it is not a real currency because it is not issued by the monetary authorities, and it does not have monetary attributes such as legal compensation and compulsion. In nature, bitcoin should be a specific virtual commodity, which does not have the same legal status as currency, and cannot and should not be used as currency in the market.

Kexing COVID-19 vaccine has been discontinued and inactivated vaccine is no longer recommended.

On January 10 th, a book called"Stop issuing performance pay scheme for COVID-19 project"The document was circulated on the Internet and signed by Beijing Kexing Zhongwei Biotechnology Co., Ltd., which mentioned that the company’s COVID-19 vaccine has been completely discontinued and the company has no COVID-19 vaccine products for sale at present.

At noon on January 10th, Jimu journalist called the product consultation hotline of Kexing Holding Biotechnology Co., Ltd., and the staff confirmed it.Kexing’s COVID-19 vaccine has been discontinued. If you still need to inject this product, you should ask the local CDC if it is in stock.

It is worth noting that there are still a variety of vaccines for new strains that can be injected in various parts of China.

Kexing COVID-19 vaccine has been discontinued.

Many companies have "got off the bus" before.

According to Jimu News, on January 10th, a document named "Stop Issuing Performance Pay Scheme for COVID-19 Project" was spread on the Internet. The date of signing the scheme was January 9th, and it was stamped with the official seal of Beijing Kexing Zhongwei Biotechnology Co., Ltd., which mentioned that at this stage, the company has stopped production of COVID-19 vaccine and the company has no sales of COVID-19 vaccine products at present, and the company decided to stop issuing performance pay for COVID-19 project for existing employees from January 2024.

Beijing Kexing Zhongwei Biotechnology Co., Ltd. is a subsidiary of Kexing Holding Biotechnology Co., Ltd. At noon on January 10,The staff of the product consultation hotline of Kexing Holding Biotechnology Co., Ltd. confirmed that at present, the COVID-19 vaccine of Kexing of the company has been discontinued. If the product needs to be injected, it is necessary to ask the local CDC if it is in stock.As for the authenticity of the online transmission of "Stop Sending Performance Pay Scheme for COVID-19 Project", the other party said it was unclear, and she was only responsible for product consultation.

In fact, since 2023, a number of companies that have been developing COVID-19 vaccine have either announced a change of direction or stopped investing, or their financial data reflect the "sequela" of "slow sales" of COVID-19 vaccine.

On July 19th, 2023, COVID-19 Microorganism Tianci Factory, one of the three musketeers of domestic mRNA vaccine, suspended its trial operation because there was no demand for vaccine production in the near future. All this was only two and a half years after it obtained the clinical approval of COVID-19 mRNA vaccine in January 2021. At that time, COVID-19 mRNA vaccine of Microorganism was the second domestic COVID-19 mRNA vaccine that entered the clinical stage.

For COVID-19 vaccine, Clover Bio, a Hong Kong-listed company, can be described as "putting all your eggs in one basket". In June, 2022, Clover Bio announced that it would give priority to the allocation of all resources to COVID-19 vaccine project, suspend the investment in the other three clinical pipelines, and reduce the investment in non-COVID-19 projects and new projects. In December 2022, COVID-19 vaccine SCB-2019(CpG 1018/ aluminum adjuvant), a recombinant protein of clover, was put into emergency use in China, and was officially launched for the first time in February 2023.

However, in the semi-annual report of 2023, Clover Bio said that due to the ever-changing and low overall demand for COVID-19 vaccine from China and countries around the world since 2023, the company predicted that COVID-19 vaccine sales in 2023 would not bring meaningful financial contribution. Its vaccine layout turned to respiratory diseases such as RSV and influenza.

In April 2023, the "low-cost operation notice" of Shangyao Kangxinuo was spread on the Internet. The content of the notice shows that it is decided to suspend the production line from April 4 for a period of 180 days. According to Red Star News at that time, the staff of Kangxinuo patient answering hotline introduced that the COVID-19 (vaccine) production line here was temporarily suspended, and there was no problem here at the headquarters. Now the demand for COVID-19 vaccine is not so great, so the production line of Shanghai Kangxinuo COVID-19 (vaccine) has been temporarily stopped, which will not affect other aspects.

Chang Rongshan: Inactivated vaccine is not recommended at present.

In February 2023, a research paper published by domestic researchers in the latest issue of China CDC Weekly stated that,"Although the protective efficacy of the third dose of Kexing inactivated vaccine can be improved to more than 70% within one month after homologous inoculation, its predictive efficacy will gradually decline to less than 50% after six months."

For COVID-19 infected people whose clinical endpoint is "COVID-19’s symptoms", the research results show that after 28 days and 6 months of intensive immunization, the protective effect of three doses of inactivated Kexing vaccine is only about 30% and 10%. Among them,The predicted protective effect of three doses of Kexing inactivated vaccine on Omicron BA.4/5 is even lower.

According to the interface news, virologist Chang Rongshan reminded that,Inactivated vaccine is not recommended at present.It pointed out that the antigenicity of the current epidemic strains has changed greatly, and the effect of inactivated vaccine will be much worse than that of other technological vaccines."It is best to play mRNA vaccine and recombinant protein vaccine."

According to JingJing. com, Xu Yue, an insider of a company that had previously researched and developed vaccines in COVID-19, said, "The research and development cost is one aspect, but the key is that you have developed it, and the virus has mutated, so the research and development speed can’t keep up at all. Vaccine iteration is too fast, and enterprises really can’t afford it, especially the cost of clinical trials. Before it is commercialized, the vaccine will be outdated first. "

Xu Yue told reporters that unlike the flu virus, which may go round and round, Covid-19 has been upgrading all the way, and the popular virus will not come again, and the old virus will not come. Therefore,Once the new COVID-19 vaccine appears, the old vaccine can be said to be "out of the historical stage".

A number of XBB vaccines were approved for use.

However, people’s willingness to vaccinate has obviously decreased.

According to Jingjing.com, on December 28th, 2023, the National Health and Wellness Commission held a press conference on the prevention and treatment of respiratory diseases in winter. Peng Zhibin, director of the Department of Respiratory Infectious Diseases of the Infectious Diseases Management Office of China CDC, said that recently, the spread of JN.1 (the second-generation sub-branch of BA.2.86 mutant in Omicron, Covid-19) has risen rapidly abroad and has become the main epidemic strain.

"The mutant JN.1 belongs to Omicron. Recently, according to the existing evidence, the World Health Organization believes that JN.1 has strong transmission ability and immune escape ability, but there is no evidence to suggest that its pathogenicity is enhanced. Previous infection and vaccination with XBB (Omicron subtype variant strain) vaccine have a cross-effect of immune protection, and it is predicted that the public health risk brought by it is low. " Peng Zhibin said.

At present, many XBB vaccines have been approved for emergency use in China. In June, 2023, the recombinant trivalent Covid-19 (XBB+BA.5+Delta mutant) trimer protein vaccine (hereinafter referred to as WEEK XBB vaccine) was put into emergency use in a certain range. In December, companies such as Shenzhou Cell, Kangxinuo and Livzon Group also announced that COVID-19 vaccine was included in emergency use.

According to the interface news, a domestic vaccine industry practitioner said,At present, the proportion of people’s willingness to vaccinate COVID-19 vaccine has obviously decreased, and the official has not clarified the requirements for vaccination indicators.All this makes "promoting vaccination in COVID-19" less urgent than before, which reduces the motivation of CDC. He said, "For example, if a company has a product approved, as long as it is developed and produced, the company will definitely want to be recognized in the market, and there is no situation in which the company is not enthusiastic. But in fact, from the step of bidding access, many provinces and cities have no enthusiasm. "

Rong Shan, a virologist, also said that the public is not willing to vaccinate COVID-19 vaccine at present. If COVID-19 vaccine is purchased, but not many people come to vaccinate it, it will easily lead to a backlog. Unlike ordinary commodities, vaccines have strict requirements for transportation and storage, and they will be wasted if they are not used after expiration.

Original title: Kexing COVID-19 vaccine has been discontinued! Many companies have long since "got off the bus", inactivated vaccines have not been recommended, and many XBB vaccines have been approved.

It is shocking that the court heard Jackson’s last recording and photo before his death.


Conrad Murray had tears in his eyes during the trial.


The day before Jackson’s death and the day after his death


Jackson’s photo, which was exposed at the trial, also said "murder" in English.

  On September 27th, local time in Los Angeles, the case of Conrad Murray, Michael Jackson’s personal doctor, accused of manslaughter was heard again in the Los Angeles High Court. Jackson’s parents and family members appeared in court, and a large number of media and fans were waiting at the gate of the court.

  During the trial, the prosecutor played a final recording of Jackson’s life, which was recorded by Murray. He talked about the concert he was going to hold at that time in a slow voice, and still wanted to build a children’s hospital with the proceeds of the performance. The vague tone of Jackson in the recording was accused by the prosecutor of being evidence of Murray’s "serious dereliction of duty". In addition, the prosecutor also carefully analyzed the pictures before Jackson’s death from every angle, including the pictures of the day before his death, the pictures at home on the day of his death, and the recordings and pictures before Jackson’s death exposed this time, which surprised and shocked the world.

  Prosecutors believe that Jackson’s slow tone in this recording shows that he had taken an anesthetic at that time, which shows that Murray knew the powerful side effects of propofol, which is probably the cause of Jackson’s death. However, after Murray injected Jackson with anesthetic, he didn’t have suitable equipment to monitor the situation after taking the drug, and he didn’t tell other doctors about his medication to Jackson. Moreover, when he found that Jackson was not well, he called "911" 24 minutes later. The prosecutor said that this was Murray’s "serious dereliction of duty" and led to Jackson’s death.

  After this recording was exposed on the Internet, many netizens even called it "shocking", indicating that it sounded "creepy". The chief prosecutor told the jury that what Murray, a private doctor, had done was tantamount to "medical abandonment". Prosecutors said that the relationship between Jackson and Murray was that of employers and employees, not that of patients and doctors. "Murray didn’t give Jackson the treatment he deserved. He abandoned Jackson."

  In the evidence-giving stage, the first person to testify in court was Ortega, the director of Jackson’s concert "this is it". Ortega said that Dr. Murray had assured him of Jackson’s health. Ortega also said that Jackson told himself to spend more time on concerts and leave them to fans. He also hoped to take this opportunity to let everyone go to "heal the world" and take good care of the earth and people around him. 


A large number of fans gathered outside the court.


Conrad Murray wipes his tears

[field restore]

  Conrad Murray claimed that Jackson stopped breathing at 11 am on June 25, 2009. However, according to the telephone records at the scene, it was not until 12: 21 that someone called 911. Jackson’s former bodyguard testified that on the day of Jackson’s death, Murray asked himself to call 911 after collecting the medicine. Medical staff and emergency room doctors testified that they thought Jackson died in his own bedroom before being taken to the hospital. Murray insisted on rescuing Jackson until he was sent to the hospital. The medical staff also said that Murray did not tell them that he had injected propofol into Jackson. At the same time, Murray’s cell phone records show that he spoke by phone before and after giving Jackson propofol and sedatives.

[Case Review]

  On June 26, 2009, Jackson died, and the chief coroner of Los Angeles announced his cause of death in Houston court, saying that he was killed by injection of propofol, a powerful anesthetic, and it was a homicide.

  On February 12, 2010, Jackson’s personal doctor Conrad Murray was arraigned by a local court in Los Angeles, but in the end, the judge found Murray not guilty of manslaughter, and Jackson’s family said they would appeal.

  After a six-day pre-trial hearing on January 12, 2011, the judge of the Los Angeles High Court finally decided that Murray would be prosecuted again for manslaughter and revoked Murray’s medical license in the state, but Murray himself did not plead guilty.

  On January 25th, 2011, Murray was formally charged with manslaughter.

  On September 9, 2011, the jury selection for Jackson’s personal doctor’s manslaughter case began.

Du Zhaocai is the highest-ranking official in football, and only two vice-chairmen of the Football Association remain in operation.

On March 23, 2023, Du Zhaocai attended the annual work conference of key cities of national football development.

According to the website of the State Commission for Discipline Inspection of the Central Commission for Discipline Inspection on April 1, Du Zhaocai, a member of the Party Group and Deputy Director of the State Sports General Administration, is suspected of serious violation of the law and is currently undergoing disciplinary review and supervision investigation by the State Commission for Discipline Inspection. Du Zhaocai is currently the party secretary and vice-chairman of China Football Association, and he is also the highest-ranking official in the anti-corruption storm in football.

Du zhaocai.

Nine people were dismissed, and Du Zhaocai was the highest-ranking official.

According to public information, in the past 141 days, nine related persons of China Football Association have been investigated. As early as November 26, 2022, former China men’s football coach Li Tie was suspected of violating the law; With the final of the FA Cup, the last event of China football in the 2022 season, ending in mid-January 2023, the anti-corruption storm once again set off a climax.

On January 19, 2023, Liu Yi, former secretary general of China Football Association, accepted the supervision and investigation, and Chen Yongliang, executive deputy secretary general of China Football Association and Minister of State Administration, accepted the review and investigation; On February 14th, China Football Association President Chen Xiaoyuan was investigated.

At the "Ministerial Channel" of the National People’s Congress this year, Gao Zhidan, director of the State Sports General Administration, said in response to questions related to the "three big balls" that, realistically speaking, for a long time, the development of the three big balls in China, especially the men’s events, was not satisfactory, the level of men’s football dropped all the way, and there were many chaos in the football industry, which formed a strong contrast with the requirements and expectations of the CPC Central Committee and the people of the whole country.

Gao Zhidan said, we should focus on the outstanding problems in the current "Three Balls" work, such as lack of spirit, lack of righteousness, and weak style of work, and persist in changing our style of work, strengthening our responsibility, and grasping implementation. Resolutely crack down and severely punish corruption and fake gambling in football and other fields, correct the wind and discipline, be strict in discipline, improve the system, strengthen the rules, and comprehensively repair and reconstruct the good ecology of the healthy and sustainable development of the’ three big balls’.

On March 27th, The Politburo Standing Committee (PSC) of the CPC and Li Xi, leader of the Central Inspection Work Leading Group, attended the National Inspection Work Conference and the first round of the 20th Central Inspection Mobilization Deployment Meeting and delivered speeches. Li Xi stressed that to carry out the mobile patrol of the State Sports General Administration, we should focus on fulfilling the party’s leadership functions and responsibilities, implementing the major decision-making arrangements for building a sports power, and thoroughly find out and promote the solution of corruption and deep-seated institutional mechanisms in the sports field, especially in the football field, so as to provide a strong guarantee for building a sports power.

Du zhaocai.

After the two sessions, football anti-corruption refreshed the official level record.

On March 24th, Wang Xiaoping, director of the Commission for Discipline Inspection of China Football Association, and Huang Song, minister of competition department, were suspected of serious violation of discipline and law, and were investigated. On March 29th, Yu Hongchen, former vice chairman of China Football Association, was investigated, and Dong Zheng, former general manager of Super League Company, was investigated. It is worth mentioning that, as the chairman of the current IAAF, Yu Hongchen was a bureau-level cadre, and at that time he was already the first bureau-level cadre to fall in the anti-corruption storm in football. ?

Du Zhaocai, as the deputy director of the General Administration, is a deputy ministerial-level cadre, which has set a new record for football anti-corruption officials. In fact, the anti-corruption storm in football started at the end of 2009, and the highest-level officials such as Xie Yalong and Nan Yong were also limited to the bureau level. This time, the deputy ministerial-level cadres were dismissed, and their ranks were also the highest among the officials who were dismissed in previous football anti-corruption storms.

According to public information, Du Zhaocai, 63, who is currently the deputy director of the State Sports General Administration and the party secretary and vice chairman of the China Football Association, once served as a director of the FIFA Council, chairman of the AFC Referee Committee, executive chairman of the China Organizing Committee of the 2023 AFC Asian Cup and chairman of the East Asian Football Association.

Du Zhaocai’s personal work experience began to intersect with football in 2017-from June 2017, Du Zhaocai was appointed as the assistant director of the State Sports General Administration and the party secretary of the China Football Association by the director of the Tianguan Center; In October 2018, he was promoted to deputy director of the General Administration, responsible for football-related work; In 2019, he served as vice chairman of China Football Association and director of FIFA Council. In April last year, Du Zhaocai was elected as the new president of the East Asian Football Association (from 2022 to 2026). At the beginning of this year, Du Zhaocai failed to run for FIFA director, and he ranked last among the seven candidates.

According to official website, the State Sports General Administration, Du Zhaocai is responsible for football-related work, docking the inter-ministerial joint meeting of FIFA, AFC and the State Council football reform and development, and is responsible for the training and participation of national football teams at all levels, as well as the bidding and preparation of various events held in China, as well as youth football and mass football; Be responsible for the training and competition of track and field, swimming, synchronized swimming, diving and other summer events, and the preparation of various events held in China; And other work assigned by the main responsible comrades. Instruct the Football Association and contact the Football Development Foundation; In charge of track and field center and swimming center, guiding the work of track and field association.

Du zhaocai.

He has repeatedly denounced football corruption in public.

According to the Nanfang Daily, Du Zhaocai has repeatedly denounced football corruption in public-at the National Conference on Competition Discipline and Anti-Doping Work in the Football Industry held in August 2022, Du Zhaocai emphasized that the competition discipline and anti-doping problems, especially the problem of "fake gambling on the black", are the concentrated expression of unhealthy trends in the football industry and a cancer that affects the healthy development of the football industry.

"The vast number of football practitioners should fully understand the special significance of competition discipline and anti-doping work to football work, thoroughly investigate and analyze the problems, take resolute and effective measures to promote competition discipline and anti-doping work, crack down on the rising trend of’ fake gambling on black’ in football field with zero tolerance, create a clean and healthy football style, and promote the healthy development of football in China." Du Zhaocai said.

Just about half a month ago, the Chinese Football Association held a meeting of all cadres. At the meeting, Du Zhaocai said that in the face of the outstanding problems in the current football industry, we must have the courage to face the problems directly.

"Deeply learn from the lessons of a series of recent corruption cases, learn from mistakes, learn from cases, promote reform by cases, find out the reasons, plug loopholes, improve systems and mechanisms, be brave in taking responsibility and fighting, manage and solve ideological problems such as bad tendencies and negative slack in the association, strengthen confidence, make full efforts, change style, break through difficulties, get back on its feet, and strive to open up a new football in China.

According to the official website of the Football Association, on March 23rd, the annual work conference of key cities for national football development was held in the National Football Training Base (Xianghe). Du Zhaocai attended the meeting and delivered a speech.

After Du Zhaocai’s fall, only two vice-chairmen of the Football Association remained in operation.

There are only two vice presidents left in the Football Association to keep running.

According to Beijing Youth Daily, Du Zhaocai’s last public appearance in China Football Association was on the afternoon of March 24th. On the morning of the same day, the news that Huang Song, director of the Competition Department of China Football Association, and Wang Xiaoping, director of the Disciplinary Committee of the Association, were taken away for investigation on suspicion of violating discipline and law was confirmed by official channels.

On the afternoon of the same day, the China Football Association made a briefing on the situation of these two people internally, and at the same time took this opportunity to give a warning education to all middle-level cadres of the Football Association again. The form was the same as that of the anti-corruption warning meeting held after the original China Football Association President Chen Yuyuan, former Secretary-General Liu Yi and Executive Deputy Secretary-General Chen Yongliang were taken away for investigation.

It is worth noting that Du Zhaocai never appeared in the office of the Football Association after attending the anti-corruption warning meeting of the Football Association and speaking at the meeting. This week, Gao Zhidan, director of the General Administration of Sports, and his party went to Liaoning for investigation, and Du Zhaocai was not among them.

After Chen Xiaoyuan and Liu Yi were investigated, the daily work of the Football Association was always presided over by Du Zhaocai. Now, under the investigation of Du Zhaocai, there are only two vice-chairmen in charge of specific business, Gao Hongbo and Sun Wen, secretary of the Discipline Inspection Commission Yan Zhanhe and deputy secretary-general David He, in China Football Association.

Who will be responsible for the daily work next remains to be determined. Therefore, the outside world is also worried that whether the new season Super League can start on April 15th as scheduled will be marked with a big question mark.
