1. The federal court reinstated the grey wolf conservation law, saying that it was still facing the crisis of "being on the verge of extinction".

[Comprehensive News]After former President Trump removed the gray wolf from the list of protected animals, many activists protested, and now there is finally a turning point. Judge White of the Federal Court for the Northern District of California ruled that the decision to remove the gray wolf from the list of protected animals was ill-considered and reversed the previous government’s regulations.

White pointed out that although the gray wolves in the Great Lakes and the northern Rocky Mountains have been successfully rehabilitated, the Fish and Wildlife Service of the United States has not considered that the gray wolves outside these areas still face great survival threats. Since Trump announced the removal of grey wolf conservation, the frequency of hunting grey wolves in some areas has soared. Last year, it was even reported that a hunter in Wisconsin killed 200 wolves within 60 hours, exceeding the state’s upper limit of 119, forcing the authorities to announce the early end of the hunting season.

2. The closure of demonstrations at individual border ports in Canada ended. Senior officials said that they would consider using the emergency law.

[Comprehensive News]On February 13th, local time, the Canadian police took enforcement action at some ports that were blocked by demonstrators who opposed epidemic prevention restrictions for many days on the Canada-US border. Among them, Ambassador Bridge Port, as one of the important logistics channels between Canada and the United States, reopened in the middle of the night. Demonstrators who have occupied the core area of the capital Ottawa for 17 days have initially reached a compromise with the municipal government.

Canadian Federal Emergency Preparedness Minister Blair confirmed in interviews with different TV media on the 13th that the federal government has discussed the possibility of using the Emergency Law to deal with the continuous large-scale demonstrations in the capital. The Canadian government has never actually used this law in the past. However, demonstrations continue in many parts of the country. At two Canadian-American border crossings, Coutts in Alberta and Emerson in Manitoba, the demonstrations continued to be blocked.

3. The injured party accepts the compensation agreement of 2.7 billion yuan for boy scout sexual abuse.

[Associated Press]Boy Scouts of America reached a compensation agreement for victims of sexual abuse, which has been supported by the Survivors’ Committee representing 82,200 claimants, and it is expected to pave the way for ending the biggest bankruptcy reorganization case of boy scouts involving child sexual abuse. When the Boy Scouts filed for bankruptcy reorganization two years ago, they proposed a plan to compensate the victims of sexual abuse for 2.7 billion yuan. However, due to criticism, they did not get wide support, and it was difficult for the bankruptcy application to pass the court.

The Boy Scout’s compensation plan must be supported by 75% survivors of sexual abuse before it can be accepted by the bankruptcy court, otherwise it will be easy to face judicial challenges. However, the support rate of the compensation plan last month was 73.6%, and now it is very important to get the support of the Survivors’ Committee. The new compensation plan adds a compensation trust for survivors of sexual assault, which can be considered separately by independent claimants, and survivors of severe sexual assault can get more compensation according to their injuries. The law firm that helped reach an agreement said that the compensation trust will strive for more funds.

4. Defending "harm reduction" The Federation emphasizes: no safe syringes are provided for drugs.

[Comprehensive News]The Biden administration announced yesterday that the publicity program aimed at preventing illegal drugs will not provide funds for crack, amphetamines and other drug users to obtain safe syringes. Health Minister Xavier Becerra and White House Drug Policy Advisor Rahul Gupta issued a joint statement saying that there will be no federal funds to provide syringes for safe drug users directly or by applying for reimbursement.

The scale of the federal program aimed at preventing illegal drug addicts from diseases, injuries and other collateral injuries reached 30 million yuan, and social service organizations and local governments applied for "harm reduction" funding subsidies last week; Specific measures of "harm reduction" include providing specific space for drug users to inject drugs, but they should be supervised to prevent drug overdose.

5. Failing to repair the automatic mail sorter, the IRS lost nearly 500 million interest in three years.

[Associated Press]The report of the inspector general of the State Administration of Taxation (IRS) pointed out that the IRS did not repair the faulty automatic mail sorter, so employees had to manually sort tax letters, which greatly slowed down the acceptance speed and caused the federal government to lose nearly 500 million yuan in interest from 2019 to 2021. According to the investigators, these machines, called "SCAMPS", play an important role in the tax refund processing system of the IRS. These machines are responsible for automatically distinguishing which envelopes contain taxes, so that the IRS can quickly accept and deposit the money.

However, these machines have been used for 20 years and have been in disrepair for a long time, often missing letters with Huijin; The IRS staff had to turn off the machine and rely on manual sorting and searching for letters, but the processing flow also slowed down. Kenneth Corbin, head of the Department of Wages and Investment of the State Administration of Taxation, asked to replace the machine before December 15, 2024; However, with a monthly loss of 10 million yuan, the United States may lose more than 350 million yuan.

6. The children of "inherited admission" alumni of prestigious schools were criticized for the "unfair cycle" and urged to abolish it.

[Associated Press] From the campus to the Congress, there is a growing call from all walks of life for top universities to abolish their preference for enrolling alumni children. When the children of top university alumni apply to study, the university will give them priority points. This practice is called "legacy admission", which has been practiced for decades. Critics accuse it of giving the least needed students an unfair advantage.

It is reported that Ivy League students are putting pressure on the school to give up the inheritance admission policy. Hundreds of students and alumni from 30 universities vowed to oppose this policy, so they no longer donated money to the school. Many prestigious schools defend the inheritance of admission. Senior officials of Harvard and other schools pointed out that the status of alumni children is only one of many factors to consider in admission applications. School grades, academic test scores and achievements in extracurricular activities all affect admission, and alumni children only give some students a slight advantage at best.

7. A new drug for the treatment of COVID-19 was authorized for emergency use in the United States. The US Drug Administration: New drugs cannot replace vaccination.

[Comprehensive News]The US Food and Drug Administration recently granted an emergency authorization for the use of a monoclonal antibody drug that can be used to treat the infection of mutant Covid-19 Omicron strain. The US Drug Administration issued a communique on the 11th, saying that this new drug, named bebtelovimab, developed by Eli Lilly, USA, is authorized to treat adults with mild to moderate diseases and adolescent COVID-19 patients who meet certain conditions, but not COVID-19 patients who have been hospitalized or need oxygen therapy.

According to the communique, this monoclonal antibody drug needs intravenous injection, and it can reduce the risk of hospitalization and death caused by Covid-19 infection by combining with the spike protein on the surface of Covid-19. The FDA stressed that this new antiviral drug cannot replace vaccination, and people who meet the vaccination conditions should also be vaccinated with COVID-19 vaccine.

9, can swim independently for over 100 days! Human cardiac muscle cells are made into "artificial fish"

Harvard University in the United States cooperated with researchers from Emory University to make a completely autonomous "artificial fish" from myocardial cells derived from human stem cells. This biological mixing device contains both biological and artificial parts, and can swim in the water for more than 100 days through myocardial contraction. This achievement is helpful to develop an artificial heart made of living muscle cells and provide a platform for studying heart diseases such as arrhythmia. Related papers were recently published in the journal Science.

The device was inspired by the shape and swimming action of zebrafish. The artificial zebrafish has two layers of muscle cells, one on each side of the caudal fin. The researchers used external light gene stimulation to control its muscle contraction and make it swim like a fish. This innovation provides a model for the study of cardiac rhythm signals, and also for understanding the pathophysiology of sinus node dysfunction and arrhythmia.

10. Musk: Star Boat may make its first orbital flight in the next few months.

[Comprehensive News]Elon musk, founder and CEO of American Space Exploration Technology Company, said recently that the company’s next-generation heavy-duty launch vehicle "Star Boat" may be approved by the regulatory authorities as soon as March, so that it may make its first orbital flight in the next few months. According to reports, Musk said at a press conference held at the "Star Boat" R&D and test base in southern Texas that Space Exploration Technology is still waiting for the relevant approval results of the US Federal Aviation Administration, and the next phase of the "Star Boat" can be launched after approval.

Musk said that although this project may fail, he is confident that the "Star Boat" will reach the scheduled orbit before the end of this year. "Star Boat" is a recyclable rocket, which is larger than the existing "Falcon 9" and "Falcon Heavy" launch vehicles of Space Exploration Technology Company. Its design goal is to send people and goods to earth orbit, the moon and Mars. The "Star Boat" can send more than 100 tons of load into Earth orbit.

11. Hundreds of sharks gather near the coast of Texas, USA.

According to the Daily Star, a rare picture of hundreds of sharks gathering near artificial coral reefs in Texas, USA, was recently posted online. Hundreds of straight-toothed sharks wandered around the reef, and the researchers called this scene a "very rare discovery." This straight-toothed shark can usually grow to more than 2 meters long and weigh more than 90 kilograms. They usually don’t attack humans.

Researchers from the Fishing Fish Science and Conservation Center took this picture at an artificial coral reef 6 miles (about 10 kilometers) away from O ‘Connor Harbor. The agency recently uploaded this video on social media. They said that "these fish schools are very rare, indicating that the fish population in this area is very healthy."

　　Breaking the "SCI supremacy" of papers is an important measure to change the pursuit of quantity into the pursuit of quality, which will have a far-reaching impact on breaking the utilitarianism and quick success in scientific and technological innovation, removing the academic bubble and shaping the excellent atmosphere of practical innovation. Recently, the Ministry of Education and the Ministry of Science and Technology issued "Several Opinions on Standardizing the Use of Relevant Indicators of SCI Papers in Colleges and Universities and Establishing Correct Evaluation Orientation" (hereinafter referred to as "Several Opinions"), and put forward ten specific opinions on breaking the "SCI supremacy" of papers and optimizing academic ecology.

　　What is the significance of cracking "SCI worship" to the establishment of scientific and technological evaluation mechanism in the new period? How to establish a scientific evaluation system after breaking the "SCI supremacy"? What explorations have universities made in this regard? The reporter recently conducted an interview.

　　Excessive pursuit of SCI papers distorts the pursuit of scientific and technological innovation value

　　Since SCI (scientific citation index) was introduced to China in the late 1980s, it has provided a source of information and data for researchers in Chinese universities and scientific research institutions to understand international academic trends, and also opened a channel for disseminating academic achievements to the outside world, which has greatly promoted the rapid development of scientific research in China, especially basic research.

　　However, in recent years, the number of SCI papers, cited times, highly cited papers, impact factors and derived ESI rankings have become the core indicators of academic evaluation, as well as professional title evaluation, performance appraisal, talent evaluation, subject evaluation, resource allocation, school ranking and other aspects, which has led to excessive pursuit of SCI papers and related indicators in scientific research work in colleges and universities, even aiming at publishing the number of SCI papers, high-impact papers and highly cited papers. There are some problems in scientific and technological innovation, such as distorted pursuit of value, exaggerated and impetuous style of study and quick success, which are not conducive to the high-quality and connotative development of higher education, can not meet the requirements of educational reform and development in the new era, and are not conducive to the construction of a strong country in education and science and technology.

　　According to Lu Jian, academician of Chinese Academy of Sciences and president of Nanjing University, since the reform and opening up, China’s scientific and technological development has roughly gone through three stages. First, the stage of comprehensive transformation: completely changing the problem of not attaching importance to science and technology during the Cultural Revolution, promoting the arrival of scientific spring and bringing scientific and technological innovation to the international stage. Second, the stage of large-scale development: the framework of scientific and technological innovation system has been fully established, major breakthroughs have been made in several fields, and many scientific and technological indicators are among the best in the world. The third is the stage of high-quality improvement: building an innovative country and blowing the horn of marching into the world’s technological power. At present, the root cause of the problem is that the economic and social development in the new era has required science and technology to enter the stage of high-quality upgrading, while the current evaluation system is still in the stage of large-scale development, which cannot keep up with the new requirements of the new era and new stage of science and technology development.

　　"In the early stage of scientific research development in domestic universities, encouraging the publication of SCI papers has a positive effect on improving the level of scientific research and should be affirmed. However, as China’s scientific and technological innovation enters the stage of promoting high-quality development with high-quality innovation, if SCI papers are still used as the only indicator to evaluate the level of scientific research, it is a manifestation of lack of self-confidence, which will lead to the loss or even alienation of goals. " Jin Li, an academician of the Chinese Academy of Sciences and executive vice president of Fudan University, believes.

　　According to Yi Fan, president of the Institute of Science and Technology of Shandong University, in recent years, the state has issued a series of policies and measures, such as the State Council’s Opinions on Strengthening Basic Scientific Research in an All-round Way, Opinions on Deepening the Reform of Project Evaluation, Talent Evaluation and Institution Evaluation, and breaking the "Five Merits" and "SCI supremacy". The core is to enhance the original ability of scientific and technological innovation and enhance the quality and contribution of scientific and technological development.

　　"The contribution of SCI papers exists, which is China’s business card in the world and the expression of China’s academic level and international influence, but this kind of competition should be of high quality. At present, improving quality on the basis of ensuring a certain amount can create a better scientific research atmosphere. " Yi Fan said that breaking the "SCI supremacy" is not to deny the publication of SCI papers, let alone to oppose them, but to encourage the publication of high-quality and constructive papers, not to follow the trend and even lead to academic misconduct.

　　According to Chen Qiang, a professor in school of economics and management, Tongji University, SCI is just a tool for document retrieval, with its specific screening angle, logic and standards, but it has been overused and distorted.

　　Chen Qiang analysis, first of all, financial investment in science and technology requires performance audit and needs the support of performance indicators. Scientific research organizations in colleges and universities have a strong administrative color, so it is necessary to promote related work. As a result, in some colleges and universities, SCI papers have become explicit indicators of scientific research level and discipline construction performance, and even turned into "baton" of scientific research activities. Secondly, after the reform and opening up, in the international academic competition in most fields, Chinese universities are mainly in a state of "following". When the academic level and governance maturity are not too high, there are also practical considerations in cost control and efficiency improvement when choosing indicators such as SCI papers. After all, at a specific stage of development, taking SCI papers as academic evaluation indicators is simple, intuitive and easy to understand and implement.

　　Establish and improve the evaluation system according to the "category"

　　In terms of how to break the "SCI supremacy" of papers, "Several Opinions" put forward a number of specific measures, such as establishing and improving the classified evaluation system, improving academic peer evaluation, vigorously reducing project evaluation, talent evaluation and institutional evaluation, and reversing the utilitarian tendency of assessment and reward.

　　Yi Fan believes that the core of Several Opinions is to adhere to the problem orientation and oppose "only papers". It is not to deny the value of papers and oppose the publication of papers. It is necessary to encourage the publication of high-quality papers, return them to the academic essence, and avoid the utilitarianism of papers. Second, adhere to classified management, strengthen peer review, pay attention to the quality of results, highlight the effectiveness of evaluation, and continuously improve scientific and technological evaluation activities. Third, adhere to the combination of breaking and establishing, not only dare to "break" and resolutely break the bad direction of "only papers" in the evaluation of scientific and technological activities, but also be good at "establishing" and establishing new regulations.

　　Jin Li also believes that the key to the current problem of "SCI supremacy" lies in the fact that the number of papers is linked to the allocation of resources. Therefore, the core of standardizing the use of related indicators of SCI papers in colleges and universities and breaking away from "only papers" and "SCI first" in scientific research evaluation is to get rid of utilitarianism. The key to breaking "SCI supremacy" is not only "breaking", but also how to "stand". Exploring the establishment of an academic evaluation index system that can reasonably measure the contribution value is the embodiment of improving the ability and level of academic governance.

　　"It is impossible to measure the diversity of scientific research and academic value by using a single index. Classified evaluation, peer evaluation and representative work system are three evaluation principles that reflect the combination of quantitative and qualitative, which is conducive to the construction of ‘ SCI first ’ After the evaluation system. " Jin Li said that the key point is to correctly use the evaluation mechanism of SCI papers, instead of simply using the number of SCI papers, the number of highly cited papers, the level of impact factors and other indicators to evaluate departments, disciplines and teachers, thus forming the orientation of blindly pursuing popularity, highly cited papers and impact factors. According to different disciplines and fields, we should classify scientific research evaluation, and combine the representative work system to distinguish the evaluation criteria of papers in different fields such as basic research, applied research and technology development. At the same time, we should emphasize solving major problems of basic research, major national needs and major industrial applications, and apply them in long-term evaluation such as title promotion and short-term evaluation such as performance accounting according to the principles of accessibility and differentiation. The existing expert peer evaluation should also be improved and refined according to the principle of traceability and accountability.

　　In Chen Qiang’s view, it is necessary to establish and improve a classified evaluation system based on "category": the laws of basic research, applied research and technological innovation are different, and the research methods and results are different. Under normal circumstances, the basic research cycle is long, with "slow research", "deep research" and "cold research" as the mainstay, and the output is relatively uncertain. Applied research aims to achieve a technological breakthrough in a specific field, or to solve practical problems in production and management practice. It has a clear result orientation and needs to race against time. Technological innovation is even different. It needs one eye to look at the supply side and one eye to look at the demand side, and its performance is more relevant to the market.

　　"Evaluation work must respect the laws and characteristics of different scientific research fields, broaden the observation dimension, and pay attention to invention patents, engineering schemes, industry standards, specifications, monographs, teaching materials, reference books, proposals, special reports, policy texts, media articles, creative designs and other forms of achievements in addition to high-level papers." Chen Qiang said.

　　"Thesis is endowed with the function of scientific and technological evaluation because it is the expression carrier of professional knowledge and achievements. Similarly, academic monographs, peer-reviewed scientific and technological reports, and research results that apply or promote technological progress all have the same function as papers as evaluation criteria. The significance of objecting to paper is to find suitable evaluation methods for scientific and technological innovations of different natures. At the same time, scientific and technological reports, academic monographs and other forms of expression can complement the time-sensitive papers in the systematic nature of the results. " Du Ozawa, dean of the Institute of Science and Technology of North China Electric Power University, said.

　　In terms of peer evaluation, Du Ozawa believes that the professionalism of modern science is getting stronger and stronger, and the division of professional direction is becoming more and more obvious. For the vast majority of researchers, their work and achievements are likely to be meaningful only to their professional fields. Therefore, peer review is the premise and foundation of scientific and objective evaluation mechanism.

　　"To implement peer review, we should vigorously create a healthy and progressive scientific culture, put an end to the erosion of the unhealthy atmosphere of human society and relationship society in the scientific community, organically combine the popular double-blind review with public review, and establish a personal credit system for researchers." Du Ozawa said.

　　In addition, Du Ozawa suggested that the long-term representative work system should be implemented in scientific and technological evaluation. Scientific and technological innovation activities have their inherent periodicity and regularity, and the output of high-level achievements is often directly proportional to the investment of researchers in time and concentration. The output of the results is a spiral accumulation process. What ultimately represents a researcher’s level should be his long-term masterpiece. In most cases, the research results in recent years required by the evaluation of professional titles and the selection of talent titles only reflect the active degree of scientific and technological innovation of researchers, and the representative works, including scientific and technological reports, academic monographs and academic papers, can better reflect the height that researchers can reach.

　　Scientific and technological evaluation should return to the origin of scientific research and technological innovation.

　　The General Secretary of the Supreme Leader pointed out at the 2018 National Education Conference and the Academician Conference of the two academies that "it is necessary to deepen the reform of the education system, improve the implementation mechanism of Lide Shuren, reverse the unscientific orientation of education evaluation, and resolutely overcome the stubborn disease of only grades, only studies, only diplomas, only papers and only hats, and fundamentally solve the baton problem of education evaluation". It is necessary to reform the evaluation system of science and technology, establish a classified evaluation system oriented to the quality, contribution and performance of scientific and technological innovation, and correctly evaluate the scientific value, technical value, economic value, social value and cultural value of scientific and technological innovation achievements. This points out the direction for the reform of evaluation system, and its profound connotation is to emphasize that scientific and technological evaluation should return to the origin of scientific research and technological innovation and liberate scientific and technological personnel from unreasonable evaluation system.

　　In Lu Jian’s view, from a macro perspective, the problems that need to be paid attention to in China’s current scientific and technological development can be summarized as follows: a pair of contradictions — — The number of papers, citations and patents in China ranks among the best in the world, but its innovation ability is around 20. Two weaknesses — — Key core technologies are controlled by people, and few Nobel Prize winners; Two deviations — — Value deviation (pursuing hats and papers as goals) and behavior deviation (impetuous and utilitarian tendency). We should fully realize the overall situation, process and complexity of the evaluation system reform. This requires planning the problems of "breaking" and "establishing" from the overall perspective.

　　Nanjing University uses the principle of "one definition", "four transformations", "three reductions" and "three lines superposition" to explore and practice a scientific evaluation system that is more suitable for the needs of the new era.

　　Lu Jian introduced that "one clarity" means that under the background of "the world is in a great change in a hundred years", standing at the height of the community of human destiny, on the basis of inheriting tradition, we will try our best to explore the original issues such as "what is a university" and "who to train" and rethink the positioning, connotation, structure and function of a university. "Four transformations" is a new paradigm of university development characterized by "new system of talent training, new model of scientific research, new mechanism of team building, new promotion of teachers and students, etc." to lead "transformation of development mode, transformation of development mode, transformation of management mode and transformation of ways of doing things". The "Three Reductions" restore the essential connotation, important extension and measurement methods of related indicators, such as scores, further studies, diplomas, papers and hats, such as personnel training, scientific research and team building, so that various indicators can return to their auxiliary means of measurement in various scenes. The so-called "three-line superposition" means that the perspective of measurement mode is changed from emphasizing only the result to emphasizing the combination of the result and the process, and the evaluation elements are transformed into the three-line superposition of "excellent leading, transformation and improvement, and indicator performance", and then new elements of evaluation are put forward.Such as mode, mechanism, method, efficiency, performance, hierarchy, etc., and their scientific combination, as an alternative path to traditional evaluation methods.

　　Focusing on the goal of improving academic governance, Nie Zuoren, academician of China Academy of Engineering and vice president of Beijing University of Technology, introduced that the academic committee of Beijing University of Technology has mainly carried out three practical explorations: First, it has established academic evaluation standards oriented to "quality and classification", and established an evaluation index system that pays attention to the quality level of landmark achievements, the contribution to the promotion of this post, the influence of solving the "stuck neck" problem in key national technical fields, and the promotion of scientific and technological progress, highlighting the characteristics of disciplines. The second is to improve the construction of operational mechanism, revise and promulgate seven rules and regulations on the work of academic committees at the two levels of schools and colleges, and enhance the status and role of academic communities in academic evaluation activities. Third, the Code of Academic Ethics and Conduct has been specially formulated, which clearly puts forward a standardized management framework for the academic behavior of teachers and students and promotes academic self-discipline.

　　"The perfection of scientific and technological evaluation and academic evaluation system is the establishment of orientation and the remolding of values. It is an important part of improving the ability and level of social governance in China and will have a far-reaching impact on China’s scientific research and personnel training. Different universities are at different stages of development and have different needs. According to the spirit of the document, according to their own characteristics and development stages, combined with the actual development of disciplines, we should formulate the management methods and implementation plans for scientific and technological evaluation of our school. " Jin Li believes.

1905 movie network news　The film is adapted from the classic original work of the same name and tells the story of affection, love and growth of the four sisters of the March family. Since the release of Christmas in North America last year, the film has won unanimous praise both inside and outside the industry with its emotional core of warm-hearted healing, vivid interpretation of the immortal cast and excellent production by the top Hollywood team, and won six heavy nominations in the 92nd Academy Awards, and finally won the best costume design award.

Among them, "diana frances" Florence Pugh, born in 1996, reshaped the role of Amy, the little sister of Ma Qi’s family in the original work, and won the Oscar nomination for best supporting actress. Little Women was previously withdrawn from the archives in China due to the epidemic, and the date of the archives will be announced another day.

Amy, who is spoiled and ignorant in the original works, has always been a controversial character, but Florence vindicates Amy in the movie Little Women, showing a more real and multifaceted new little sister image. Her self-confidence, rebellion and desire, sober self-awareness and strong personality. Although she dreams of becoming a painter, she can also recognize her lack of talent; Although she insists on the concept that marriage is an economic problem, she can bravely give up the engagement of a rich and powerful family for the sake of man next door Laurie, who has always had a crush on her. Florence accurately depicts Amy’s growing process and complex personality with her strength beyond her age, which shows that the strength of being nominated for the Oscar for Best Female Matching cannot be underestimated.

In addition to the Oscar’s affirmation, Florence’s performance in Little Women has won many praises from the industry and the media. Saoirse Ronan, who plays the second sister Joe, called her portrayal of Amy "unprecedented" and let the audience see "Amy’s struggle"; Director Guilmault del Toro praised her "infinite talent" and her performance "incredible"; Washington post even commented pertinently: "Florence’s performance in Little Women achieved a rare balance. One second she captured Amy’s smart nature, and the next she showed her solemn and reserved behavior."

Florence’s successful shaping of Amy is inseparable from her belief in pursuing realism. Before filming a fight between Amy and Joe, Florence asked Ronan to slap her hard. While filming the scene where Amy fell into the lake while skating, Florence didn’t mind that she had to soak in a big cold pool repeatedly in the cold winter of December. In her own words: "The real feeling of the body helps the performance, and I can’t stand fake things."

　　CCTV News:Recently, a video of "Banana Soaking in Unknown Liquid" was circulated, and consumers were worried that the unknown liquid was toxic, and some netizens even said it was formaldehyde. So, what is the practice of soaking bananas in the video? What exactly is "unknown liquid"?

　　In this regard, the researcher of the Academy of Agricultural Sciences explained that bananas are very perishable, and the milky white liquid in the video is a preservative. It is internationally recognized that low toxicity sterilization and degradation are fast. After being registered by the competent authorities, it is allowed to be used in banana preservation, and the corresponding recommended dosage and residue limit standards are also formulated. So consumers don’t have to worry. Feel free to use it.

　　Food fraud is abhorrent, but there are always food safety rumors that poke your "pain point". With the rapid spread of the Internet, many people have seen food safety information with pictures and videos from their circle of friends, such as "So-and-so food is toxic and carcinogenic" and "Don’t eat XX". These seemingly vivid and lively food safety information are really the truth? After all, they exposed the clues in front of science and common sense, and finally ended up being rumored.

　　Multi-department joint action to defend "safety on the tip of the tongue"　

　　In the past, food fraud was mainly based on "administrative law enforcement and insufficient judicial intervention". Now "food fraud is directly punished" is expected to change this situation.

　　Food and Drug Administration: Implementing the "Four Strictest" Food Safety Penalties to People

　　On January 18th, Comrade Jiao Hong, deputy director of the State Food and Drug Administration, presided over an expert meeting, and held a special discussion and exchange on further implementing the "four strictest" requirements of the central government on food and drug safety, implementing the spirit of the instructions of "punishing people" for illegal activities in production and operation, and promoting the direct punishment of adulteration and forgery. Comrade Jiao Hong pointed out that to implement the "four strictest" requirements of the central government on food and drug safety and the spirit of the instructions to promote adulteration and counterfeiting to be directly punished and "punished to people", the Food and Drug Administration will further intensify its work, and combine the revision of the Drug Administration Law, the Regulations on the Implementation of the Food Safety Law and the Regulations on the Supervision and Administration of Cosmetics to further improve the relevant systems for punishing natural persons, and actively promote the revision of the judicial interpretation of food and drug safety.

　　Ministry of Public Security: It will directly punish food fraud.

　　On March 17, the relevant person in charge of the Public Security Administration of the Ministry of Public Security said that in the next step, the public security organs will further intensify the criminal crackdown, actively work with relevant departments to promote the direct imprisonment of food fraud, improve the judicial interpretation of cracking down on food and drug crimes, and give full play to the deterrent effect of the criminal law.

　　Cctv newsEvery time the carrier battle group is on duty, it has to wander at sea for several months. At this time, a comprehensive supply ship with large tonnage and high speed is needed to meet the massive material demand of the carrier formation.

　　Recently, the first ship of China Navy’s new integrated supply ship — — The Hulun Lake ship officially joined the Chinese People’s Liberation Army Navy sequence. The Hulun Lake ship, known as the "super wet nurse", will make the Chinese aircraft carrier formation go further.

　　Hulun Lake Ship No.965 is a new type of integrated supply ship independently developed by China and advanced in the world. Although the official did not disclose the specific information, some analysts believe that Hulun Lake Ship is a 901 integrated supply ship. This type of supply ship is the first 40,000-ton supply ship in China, which is twice as large as the Type 903 being built in batches, and its speed has also been greatly improved.

　　Hulun Lake Ship Completes the Last Short Board of Chinese Aircraft Carrier Battle Group

　　Previously, there were eight 903 large supply ships in China. The speed of the 903 integrated supply ship is less than 20 knots, while the speed of the carrier Liaoning ship is about 29 knots, and the speed of the 052D destroyer is about 32 knots. That is to say, the speed of the supply ship owned by China could not keep up with the speed of the entire aircraft carrier formation.

　　The Hulun Lake ship, with a speed of about 25 knots, can provide the naval carrier formation of China with accompanying supplies at sea, completing the last short board in the Chinese carrier battle group.

　　The power of the new supply ship has been strengthened, which has increased the rapid supply capacity.

　　Cao Weidong, a military expert, said that the integrated supply ship mainly provides oil, fresh water and ammunition to combat ships. In the past, the supply ship had small tonnage, less materials and poor wind and wave resistance. The speed of warships is relatively fast, and the speed of supply ships is relatively slow, which is easy to slow down.

　　Nowadays, after the power of the new integrated supply ship is strengthened, it can follow behind the combat ship quickly, so that it can sail together in a formation and increase the rapid supply capacity.

　　The new supply ship can realize vertical, horizontal and three-dimensional supply.

　　As mentioned in the public information, Hulun Lake Ship has broken through a series of key technologies, such as the development of new offshore replenishment devices and the overall design and construction of large-scale replenishment ships, with diverse replenishment methods and strong replenishment capabilities. So … How to understand "various replenishment methods"?

　　Cao Weidong pointed out that the new supply ship can supply vertically, horizontally and stereoscopically. In this way,The replenishment speed can be greatly increased, and several ships can be replenished at the same time, thus enhancing the ocean-going escort and combat capability of the China Navy.

　　If the supply ship is sunk, the sustained combat capability of the aircraft carrier formation will be reduced by at least 50%.

　　With the China Navy’s more and more frequent offshore training operations, it is essential to have enough supply ships. The so-called military forces have not moved, and food and grass are first. How important is replenishment for aircraft carriers?

　　The nuclear-powered aircraft carrier in the United States carries 80 aircraft, and the average fuel consumption of each aircraft is 10 tons. Assuming that each aircraft is dispatched once a day, the fuel consumption is about 800 tons, while Nimitz-class aircraft carriers can generally carry 9000 tons of aviation fuel, and according to this fuel consumption, the operational demand can only be maintained for 8-12 days.If the supply ship is sunk, it is equivalent to a reduction of 50% or even 100% in the sustained combat capability of the aircraft carrier formation.

　　Type 901 integrated supply ship will make Chinese aircraft carrier go further.

　　The full-load displacement of the 901 integrated supply ship has reached 40,000 tons. Although the specific amount of materials carried has not been made public, for example, the supply-level fast combat support ship with similar tonnage of the US military can carry about 20,000 tons of various oils and dry goods.

　　Cao Weidong said: with the increase of our country’s guarding tasks in the open sea in the future,Supply ships must adapt to the new mode of China Navy’s offshore escort and ensure the logistics supply of combat ships, especially the supply of battle groups such as aircraft carriers.. After the formation of the aircraft carrier to the far sea, not only the aircraft carrier needs to be supplemented with raw materials, fresh water, food and ammunition, but also the surrounding ships need to be supplemented. soThe integrated supply ship in the aircraft carrier formation is indispensable, which can effectively provide corresponding logistics support for the aircraft carrier battle group to sail continuously, perform tasks continuously or fight continuously.

　　The future replenishment mode will be systematic, informative, precise and automatic.

　　At present, the world’s major naval powers are continuing to develop supply ships. From the perspective of rapid supply ships, the United States is still leading the world; Although Russia currently has only one aircraft carrier formation, the supply ships are also very complete, and Britain and France also have large-tonnage supply ships. China is also vigorously developing large-tonnage supply ships.Large-tonnage and high-speed supply ships have almost become the standard configuration of naval powers.

　　In addition to large tonnage and high speed, the informationization of future supply ships is also very important.Cao Weidong, a military expert, pointed out that in the future combat, warships emphasize systematic confrontation and informational confrontation, which is also applicable to supply ships.In the future, accurate replenishment, rapid replenishment, information-based cross-linking with other ships and improvement of automation will be the development direction of supply ships.
