I remember that in the early 1980s, Jean-Paul Sartre (1905-1980) was a hot topic among young Chinese intellectuals. Speaking of Sartre, the first thing I recall is his photo of him peddling the leftist newspaper “Dyelo Narok” on the street. He is old and unattractive, hiding behind old-fashioned short-sighted glasses that look like the bottom of a wine bottle. This photo was later included in the anthology “Sartre Research” (1981) edited by Mr. Liu Mingjiu, a French literature expert. 　　When Sartre’s theories and works were widely disseminated in China, it was the time when the Chinese youth were struggling to get out of the spiritual ruins caused by the ten-year…

Recently, American researcher Deso began testing DNA in ancient cow bones found at archaeological sites in the hope of learning more about the domestication of cattle in the Americas. When he sequenced mitochondrial DNA in fossilized bovine teeth, he found that one sample had a distinctive sequence. Upon closer inspection, he was surprised to find that the sample — a tooth fragment from an adult “cow” — belonged to a horse, and that the sequence was the earliest ever made of domestic horse DNA in the Americas. Stumble upon The piece was found in the town of Leopold, one of the first settlements of Spanish settlers in North America. The…

　　Recently, the British “Guardian” released ten major scientific advances in 2022 selected by ten scientists. Among them, China’s inhaled new crown vaccine and the use of artificial intelligence to discover antibiotics were selected. 　　Inhaled vaccines induce mucosal immunity and may provide long-term protection against respiratory viruses, the report said. For people with “needle phobia”, this type of vaccine is more attractive. If these new crown vaccines work as expected, the annual booster shots will soon be a thing of the past. In addition, antimicrobial drug resistance is listed by the World Health Organization as one of the top ten public health threats facing mankind. Antimicrobial peptides are recognized alternatives to…

　　In order to achieve the two goals of “be the first to become a clean energy-based country that does not use fossil fuels” and “strive to make vehicles on the road achieve zero emissions by 2030”, the Swedish government calls on the people of the country to purchase new energy electric vehicles. However, although new energy electric vehicles have the advantages of cleanliness and pollution-free, due to the far insufficient cruising range, the car often breaks down halfway, so the general public in Sweden is not interested in buying electric vehicles. 　　After pinpointing the “pulse” of the people in the country, the Swedish Transport Administration began to “prescribe the right…

　　The Middle Ages is often referred to as the era of retrogression of Western civilization. It was the execution ground for religious trials, the hell where the Black Death took 20 million lives, and the severe cold of swords and swords and endless wars. Women in the Middle Ages were just subordinates to their masters. This tradition of gender inequality is surprisingly similar to the oriental patriarchal thought. Peasant and petty bourgeois women toiled until they stopped breathing in order to obtain food for subsistence. Most of the high-class women spent their whole lives wandering in cold castles. Become the link to maintain the interests of the two families. But…

　　Before the Second World War, the main means of transportation used by the Dutch was bicycles. But that changed in the 1950s and 1960s with the dramatic increase in the number of cars. Like many European countries, the roads in the Netherlands have become increasingly congested, with cyclists being pushed to the side of the road. 　　The surge in the number of cars in the Netherlands has led to a sharp rise in traffic fatalities. In 1971, more than 3,000 people were killed in motor vehicle accidents, including 450 children. 　　For this reason, a social movement has emerged in the Netherlands demanding that children be provided with safety guarantees for…

　　Jürgen Naumann is the caretaker of a “forgotten world” called Wunsdorf. It is a small town about 40 kilometers from the center of Berlin. Today, as a resident of Germany, he lives with remnants of the past every day. 　　The clock on the clock tower built in the era of William II stopped forever at 11:16 am. On a hot day in August 1994, all officers and soldiers of the former Soviet army evacuated the small town named Wunsdorf forever, and the small town has been recorded in history ever since. 　　Until that day, soldiers with tacked boots had been stationed in barracks with flagstones and hardwood floors for more…
