  • According to a paper published in the European Journal of Preventive Cardiology on the 20th, people who watch TV for 4 hours or more a day have a 35 percent higher risk of developing blood clots。In this study, scientists investigated the relationship between watching TV and venous thromboembolism (VTE)。VTE includes pulmonary embolism and deep vein thrombosis。The researchers used meta-analyses to combine the results of studies relevant to the topic to reach more precise and reliable conclusions。The analysis included three studies with a total of 131,421 participants aged 40 years and older who did not have a pre-existing VT.

  • According to the physicists organization network recently reported that researchers from Peking University in China, the University of Washington in the United States, Michigan State University and other institutions worked together to create the world's lightest magnesium isotope so far, magnesium-18, which helps scientists better understand how atoms are formed。The Earth is rich in natural magnesium, which was produced in stars long ago and is now an important part of the minerals of the Earth's crust and an indispensable nutrient in our daily diet。This magnesium is stable, and its nuclei do not fall apart。The new magnesium isotope, magnesium-18, is unstable and cannot be found in nature.

  • A number of new studies have shown that the mutated Omicron strain of the novel coronavirus, while spreading like wildfire around the world, appears to be far less severe than initially feared。Some scientists have speculated that the outbreak is entering a new, less worrisome phase, and that Omicron's high infectivity and low pathogenicity could signal "the beginning of the end" of the outbreak.。However, the World Health Organization's European regional official warned on the 4th that the surge in global infection rates could increase the risk of the virus mutating and even emerging more dangerous mutated strains。People attend the New Year's Eve celebration at Times Square in New York, the United States, December 31, 2021。Due to the mutation of the COVID-19 Omicron virus...

  • Recently, Egyptian scientists used three-dimensional CT (computed tomography) imaging for the first time to "digitally unseal" the mummy of Pharaoh Amenhotep I and released the details of his face。Amenhotep's physical appearance, the study found, was similar to his father's: a narrow jaw, a small nose, curly hair, and slightly protruding upper teeth。This is the first time in 3,000 years that the mummy of Amenhotep I has been virtually 'opened'。They reported their findings in the journal Frontiers in Medicine on Monday。All Egyptian royal mummies discovered in the 19th and 20th centuries have long been opened for study。…
