●On the 21st, the important zoonotic disease and severe exotic disease team of the Harbin Veterinary Research Institute of the Chinese Academy of Agricultural Sciences found that diltiazem can effectively inhibit the infection of the new crown virus in the cells and lungs of mice. Studies have shown that as a first-line drug widely used in the treatment of ischemic heart disease and hypertension, diltiazem has the potential of a new crown prevention and treatment drug. The results were published in PLOS Pathogens on the 17th. (Source: Science and Technology Daily)

Recently, the team of thomas Kenkmann, a geologist at the University of Freiburg in Germany, discovered 31 smaller craters, each no larger than the width of a football field. This is the first time secondary impact craters have been found on Earth, which may have been formed by boulders thrown by the impact and falling 200 kilometers away from the crater. The findings were published in the Bulletin of the Geological Society of America. (Source: China Science Daily)

● According to the New York Times reported on the 20th, the US Centers for Disease Control and Prevention did not disclose most of the new crown epidemic data and information it collected. When the CDC released the first data on the enhanced effectiveness of the COVID-19 vaccine against adults under the age of 65, it omitted the 18- to 49-year-old population, which makes up a large proportion of adults under the age of 65. So when U.S. federal health agencies sought advice from outside experts, experts had to rely on data from Israel to make recommendations for COVID-19 vaccinations. (Source: CCTV News Client)
