In the past 2012, many people were a little bit "terrorist", because after the interpretation of cultural works and the media's hype, the rumors of "the world will be destroyed" are almost household names. Although people sneered at this statement, thinking that it was a topic hyped by the media in order to attract eyeballs, it is undeniable that this topic brought the mysterious Mayan civilization back to the public eye. Compared with other ancient civilizations in the world, Maya civilization is inherently more mysterious: mysterious civilizations discovered by accident, disappearing suddenly for unknown reasons, prophecies of extinction, magnificent square pyramids, bloody living sacrifices, and so on. The text that has not been completely deciphered, and the location is just in the mysterious circle of 30 degrees north latitude... everything, the Mayan civilization perfectly fits all the illusions and expectations of the mysterious civilization. 　　Compare...

  On August 19, 2018, Daniel Barenboim performs at a concert at the Waldbuehne Theater in Berlin, Germany 　　In 1827, Goethe's last collection of poems "The Collection of West and East" was written. It was inspired by the works of Hafez, the most influential poet in the Arab world. Imitating the imaginary Eastern poetic world of human childhood, Goethe constructed a world of ideals that "poetry, religion and philosophy merge into one" in "The Collection of West and East". 　　But in fact, the soil in which this "Eastern poetics world" grows in the Middle East is a battleground for military strategists. Since the founding of the state of Israel, it has attacked each other with Palestine and the entire Arab world. Peace and equality have become luxuries on this land. 　　Even so, in the cracks of the war, a utopia is still struggling to grow: In 1999, Israeli conductor Daniel Barenboim and literary theorist Edward Said jointly formed a group of Isra...

 　　There is a very delicate dish in front of you. Will you eat your favorite dish first, or save your favorite dish for last? 　　The habit of investors is to eat their favorite dishes first. Investors have this habit because they pay more attention to results. If you save the food you like until the end, investors will not be able to ensure that you can eat it. This is actually a big “risk”. Investors still have a habit. They will "exclude unpredictable risks as much as possible" and will give priority to eliminating them. Therefore, if there is a risk of not being able to eat the food they like, then they will try to eat it before the risk occurs. This is the logic of investor thinking. 　　Investors already have the expected results in their minds, and then reverse the results of "what should be done now"; while the minds of workplace workers are mostly forward thinking, thinking from now to the future, and pushing forward as much as possible . Therefore, investors a...

 The macaque is an omnivorous animal, mainly vegetarian. Its brain structure, physiological functions and genes are similar to humans, and it has advanced cognitive behaviors. 　　The new crown pneumonia epidemic has been raging around the world for more than a year, and many countries have pinned their hopes on vaccination. 　　On May 3, the American Indian-born infectious disease expert Ragusa Kapila passed away in India after contracting the new crown virus, which caused widespread concern in the international world. Before going to India, Kapila had been vaccinated with two doses of Pfizer vaccine produced in the United States, but after going to India he was still infected with the new coronavirus locally and eventually died of multiple organ failure. 　　Immediately afterwards, the mutated new coronavirus that was first discovered in India was listed as a mutation of concern by the World Health Organization, indicating that the mutation of this virus is worrying. This has once agai...

 The world today is undergoing major changes unseen in a century, the international balance of power continues to change, and the geostrategic pattern is deeply adjusted. The new crown epidemic has further magnified the differences between different systems and intensified the differentiation and conflicts of interests between different countries. There are some interesting new trends, new trends and new developments in the strategic game of major powers. During Biden's just-concluded visit to Europe, the joint statement of the US-EU Summit deserves special attention. The statement not only emphasized the need for a strong "transatlantic partnership" to meet China's challenges, but also clearly stated in paragraph 24 that "cooperation in the application of sanctions must be strengthened to advance our shared foreign policy and security goals."   This is an extremely important signal. It shows that in the face of China's increasingly powerful legal counte...

 In recent years, the incidence of diabetes and colon cancer has gradually increased. More and more researchers have found that diabetes can increase the risk of colon tumors, but the mechanism by which diabetes increases the risk of colon tumors is still unclear [1-2]. Wnt inhibitor 1 (WIF1) is a secreted protein encoded by the WIF1 gene. It is an inhibitor of the Wnt/β-catenin signaling pathway. It directly binds to the Wnt protein and passes through the frizzled protein on the cell membrane. The receptor family transmits signals to the cell, causing the phosphorylation of β-catenin, a key molecule in the pathway, and promoting the degradation of β-catenin, thereby inhibiting the Wnt/β-catenin signaling pathway [3]. Studies have shown that WIF1 can inhibit tumorigenesis [4]. The Wnt/β-catenin signaling pathway plays an important role in cell proliferation, embryonic development and adult tissue regeneration. Previous studies have shown that the tumor cells of colon cancer patient...

 Most liver cancers are found in advanced stages An oncologist once said that most of the patients with cancer within 30 years of age are liver cancer, and liver cancer also causes the most deaths. The main reason is that liver cancer is difficult to detect in the early stage, and when there are clinical symptoms (fatigue, nausea, abdominal distension, pain in the liver area, etc.), the condition has developed to the point of irreversibility. Because the liver is the only organ in the body that does not have pain nerves, but it has a coating on its surface. The main function of this thin envelope is to protect the liver and separate the liver from other organs. It has no elasticity but contains a small amount of pain nerves. When the liver function is severely damaged and the liver begins to swell and stimulate the capsule, the capsule stimulates the pain sensory nerves due to the pulling, and then the person feels the feeling of hepatic pain. Therefore, there is a sentence to desc...

 In "Immortal", Milan Kundera once divided the human soul into two types, one is the soul who does addition, and the other is the soul who does subtraction. Adding people must constantly express themselves, highlight themselves, let people see themselves walking on the street, hear their own opinions and voices, and have inextricably connected with the world, otherwise they will feel lost The meaning of life. Kundera said that this kind of people are the majority. People get married and have children, constantly communicate and speak, wear fancy clothes, take photos and pose, all subconsciously to let more people remember themselves, to let the world see themselves, This emphasizes the existence of the self.   On the other hand, people who do subtraction feel that they have nothing to do with the world, and hope to live a peaceful life without being disturbed. They feel that the world is a prison, and they always want to escape from prison, so they automatically reduce the no...

 In the eyes of the public, college teachers are less expensive than middle school teachers, but the actual work content of college teachers is much more complicated than imagined: the work covers scientific research, teaching, application for scientific research projects, etc., of which the biggest pressure is the publication of papers. Recently, there have been more and more discussions on the plight of young teachers in colleges and universities. Some public opinion has pointed the spearhead at the university’s selection system for young teachers, whether they are promoted or left. Colleges and universities in most countries around the world have implemented this teacher assessment system that originated from the United States: teachers who fail the assessment will leave if they fail to reach the promotion goal. United States: Want to be hired for life, the competition is fierce The "promote or leave" system originated from the tenure system of American colleges and univer...
