● On March 19, at the press conference of the joint prevention and control mechanism of the State Council, Zheng Zhongwei, head of the vaccine research and development special class of the scientific research group, said that according to the research that has been carried out at home and abroad, the full vaccination of the new crown vaccine can significantly reduce the risk of pneumonia and severe disease caused by the Aomi Kerong variant. Enhanced immunity and sequential immunity also further reduce the rate of breakthrough infection caused by the Ami kerong variant. That said, existing vaccines are still effective against the Ami kerong variant. (Source: Science and Technology Daily)
●In recent days, the epidemic situation in many cities in Jilin Province has been grim. On March 19, Academician Zhang Boli said in an interview with the media: The overall analysis is caused by the mutant strain of Omicron, because of its strong concealment and asymptomatic infection, once the diagnosis is found, it may be that a piece of close contact around it has been positive. It is estimated that by the middle of April, it will enter a relatively stable stage, but it is not absolutely zero, and basically this wave of epidemic can be controlled. (Source: People's Daily)

Recently, Wang Baosheng, a researcher at the South China Botanical Garden of the Chinese Academy of Sciences, and Paul S. Manos, a professor at Duke University in the United States, used phylogenetics and population genetics research methods to discover the phylogenetic relationships, differentiation history, and genetic effects of interspecific hybridization of Plants in the Family Phylloscopidae. It reveals the important role of key trait innovation and interspecific hybridization in the evolution of Shell hopper species, and provides an important reference for understanding the evolutionary laws of forests in the northern hemisphere.

New discoveries
●Recently, in a new research paper published in the international top academic journal "Science", the University of Tsukuba in Japan and Peking University found that dopamine, the signal that makes the brain happy, is elevated in the basolateral amygdala region (BLA) in the brain, which is the key to initiating RAPID EYE movement sleep.

●Recently, the research group of Zhu Jian, a researcher at the School of Life Sciences of Peking University and the Peking University-Tsinghua Joint Center for Life Sciences, used the color cells of fruit fly larvae to find that insufficient intake of essential amino acids is the "culprit" that causes malnourished people to suffer from fatty liver disease. Therefore, for malnourished people, appropriate supplementation of essential amino acids, especially branched-chain amino acids, has important guiding significance for the prevention of fatty liver disease.

Look at the weather
● From March 20 to 22, there will be a large-scale heavy precipitation process in the south of the mainland, with heavy rain in 9 provinces and cities, and local heavy rain. Precipitation in some areas such as Hubei and Anhui has certain extremes and coincides with the previous heavy rainfall areas, so it is necessary to pay attention to the prevention of secondary disasters. At the same time, the temperature will also drop significantly, the cold and warm conversion is rapid, you need to add clothes in time to keep warm, beware of colds.

Look at the world
International Space Station. Xinhua News Agency issued a data map
● On March 18, NASA announced and SpaceX adjusted the time of the launch of the manned space mission Crew-4 to the International Space Station, and the launch is currently expected to be as early as April 19. NASA said this is to allow the appropriate spacing between manned space missions to operate launch and post-flight data reviews, allowing for multiple consecutive launch attempts to the International Space Station.
