High in the Indian Himalayas, Lake Rupkund (aka "Skull Lake") is one of the most bizarre and mysterious locations in archaeology. It is frozen for most of the year, but when the ice melted, the skeletal remains of hundreds of people were exposed. Previous studies of large numbers of bones found these people tended to be "above average" in height. Most are middle-aged, and some are elderly women without children. All are fairly healthy. 　　They were first discovered in 1942. The discovery immediately sparked a big debate, and these human bones have puzzled historians, scientists and archaeologists around the world like a mystery. Since then, people have been trying to find out the answer to this puzzle. Who are these people? How can you die in this inconspicuous place? 　　One of the studies was conducted by scientists from various countries led by cultural anthropologist Wilhelm Sachs of the University of Heidelberg in Germany. After a long journey, they came to thi...

 　　Writer Sanmao recorded many stories of Berbers in "Stories of the Sahara". Ouarzazate, a small town on the edge of the Sahara Desert, is the earliest homeland of the indigenous Berbers in Morocco. It still retains the "Pyramid" village built in the 12th century. Ouarzazate, known as the "Desert Gate", is also favored by directors because of its original style, abundant sunshine, and unpolluted natural environment. This is the filming location of hundreds of popular TV dramas such as "Operation Red Sea", "Cleopatra", "The Mummy", "Gladiator" and "Game of Thrones", known as "African Hollywood"! "Red Pyramid" Village 　　Ouarzazate, located in southeastern Morocco, is a small town on the edge of the Sahara Desert and the earliest home of the country's indigenous Berbers. It is located in the majestic Atlas Mountains, with the title of "Desert Gate" and "African Hollywood...

 Recently, the topic of "face recognition must wear clothes" has aroused hot debate. The incident came after a blogger said people must wear clothes when using the APP's facial recognition function because 'the camera doesn't just pick up part of the face'. This is confirmed by industry experts. In people's eyes, face recognition is of course face recognition. But in fact, the face recognition image shows the face, but the background can see the picture is not limited to the face. Such face recognition acquisition of images, it is true that "do not count" suspicion. Further, such face recognition APP in the law is also suspected of overstepping their authority or infringement. Face recognition applications need to be supported by citizen portraits, so portrait rights are the most likely to be infringed during face recognition. Face recognition can only collect the image information of the face provided by citizens. Once the collection scope is ex...

 Darwin called it a "pesky mystery" in the early 19th century, puzzled by the discovery of a sudden abundance of angiosperms in the Strata of the Cretaceous period (145m to 66m years ago), which seemed to contradict the evolutionary view that evolution is gradual. Four years ago, a sino-American team led by the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NANJING Institute of Palaeontology) discovered new fossils in Inner Mongolia, proving that angiosperms did not appear in "sudden abundance" and that their ancestral groups date back 126 million years. The mystery of the origin of angiosperms Angiosperms are considered to be large groups with well-evolved and rich species (about 300,000 species) and complex ecological habits in the plant kingdom. They are also an important part of human survival and closely related to human food, clothing, housing and transportation. For example, the vast majority of food, linen clothing, and bu...

 Despite of interstellar travel stories in science fiction let a person feel very childish, but Darwin pointed out that organisms cannot be survived in the interstellar travel, after all the long trek across generations, even if the vehicle running at the speed of light, also need to tens of thousands of years across the Milky Way disk of stars, at the same time, through the Milky Way halo structure of 10 times longer. So if we meet an alien, is likely to be their science and technology products, technology product debris may over several billion years accumulation in interstellar space, like a plastic bottle accumulation on the surface, the opportunity to detect an alien technology remains can be simply calculated from us in a nearby unit volume Numbers, rather than from the drake equation, Strictly speaking, this formula applies only to the communication signals of existing civilizations. Do alien intelligences follow the "fundamental theory of moral metaphysics" proposed b...

 New research has systematically defined health at multiple levels, including whole tissues, organs, cells, subcells and molecules. In a crude sense, health means "not being sick." But this simple definition does not really satisfy our understanding of health. A landmark review published in cell, a leading academic journal, details eight core markers of health, providing a systematic new definition of health at multiple levels, including the whole tissue, organ, cell, subcellular and molecular levels. The authors are professor Carlos Lopez Otin of the University of Oviedo, Spain, whose research focuses on cancer, aging and genome function analysis. The other is Professor Guido Kroemer of the Gustave Roussy Institute in France, who has done much pioneering work in the fields of cell biology and cancer research. Sign 1: Barrier intact The skin, gut, and respiratory tract provide a barrier between us and our environment. In addition, there are barriers of different scales in our...

 　　In this world, some people are addicted to smoking, some people are addicted to alcohol, some people are captured by betel nut, and some people are caught in drugs... And in Yemen, people go crazy for eating a kind of leaf. 　　This leaf is called "Qat". In order to eat Qat, Yemen paid a huge price: the juice of Qat can release unique chemical elements, and the strong stimulation is enough to seriously affect or even manipulate people's physiology and mind, and the harm is comparable to drugs; planting this plant requires a lot of consumption of water resources, a heavy burden for arid Yemen. In addition, in this extremely poor and food-poor country, farmers, in pursuit of higher economic benefits, have planted qat in their precious farmland - although after qat is planted, this land will no longer be able to grow any crops... … 　　helpless choice 　　If you come to Yemen and enter a city, you will find such a scene: 　　on the street, people are standing or sitting, or busy ...

 　　For immunologists, the global pandemic has been an eye-opener. The coronavirus has surprised them in almost every way. They've learned more than they've learned from decades of research, and one of the most important discoveries will make them rewrite immunology textbooks. 　　This finding relates to what we know about the innate immune system. Our two immune systems 　　As vertebrates, we are proud to have two immune systems: one is the innate immune system; the other is the adaptive immune system. 　　The innate immune system is relatively simple. It consists of a fast-reacting, universal defense system that can strike any intruder indiscriminately. One of its weapons is inflammation. Inflammation is a universal immune response to all pathogens, physical injury, and mental stress. 　　The adaptive immune system can be seen as an intelligent, efficient "special force" responsible for the development and deployment of highly specialized and precise weapons to deal with int...

 　　There is a saying at Harvard that a person's success depends entirely on his diligence in his spare time. If you can set aside two hours a night to read books, study homework, participate in some meaningful discussions or speeches, then you will find that your life is changing qualitatively. 　　In the same way, if you can make use of your weekends, you can make great progress for a few years. 　　However, in real life, how do most young people spend their weekends? 　　Some people overcompleted their learning tasks, some passed the game levels smoothly; some learned new knowledge from books, some people watched short videos for a day with their mobile phones... 　　After the "rest" on the weekend, some people gained a lot and made obvious progress. ; Some people suffer from "Monday Syndrome": either being late or feeling listless all day. 　　"Monday syndrome" refers to the symptoms of fatigue, chest tightness, and lethargy that office workers show on Monday...

 　　Not a single leaf of the peach tree is left, only a black, curved body is left, tough and cold, and I can't imagine that this tree will grow peach leaves and peach blossoms in the coming year. Later, I saw the leaves of the ginkgo tree. The ginkgo tree is really good. The fallen leaves are golden and fall on the ground like a sunset. It is pleasing to the eye and heartwarming. The persimmon tree is the slowest to lose its leaves. It will drop a few pieces today and a few pieces tomorrow. Keeping the solar terms and keeping the time, this reminds me of the self-discipline of trees. Winter is coming, and winter is the day of winter. Trees know it, and people know it. 　　The crown of the persimmon tree in November is still blue and rich. There are hundreds of persimmons hanging on the tree, some deep yellow, some light red, some light green, and people can't eat it. But there are a few light red persimmons that have been broken, with a few holes poked on them. The big holes are ...

 　　About 8 years ago, I came into contact with a business owner who crossed over to children's food from Chaowan Stationery. It is said that inter-line is like a mountain, but it has long been a routine operation to make profits across the line. He pays special attention to the packaging of the product, and also requires that the product design must be fun. For example, he said that the bottle cap of a product should be designed to look like a doctor's cap, which not only has the beautiful meaning of academic success, but also transforms the child's bottle-opening process into a fun experience similar to twisting a wrench. 　　This statement is deeply rooted in my heart. Later, an expert proposed "toy thinking". He believed that toy thinking, as a new trend in the evolution of product strategy in the Internet era, is rapidly replacing tool thinking. 　　New products, or new functions of products, not only meet the basic needs of users, but also provide users with deep...

 The world tide of scientific and technological innovation "Applying AI to environmental protection and emission reduction has the potential to increase global GDP by 3.1 percent to 4.4 percent by 2030, while reducing global greenhouse gas emissions by about 1.5 percent to 4.0 percent." With the worsening situation of global warming, energy conservation and emission reduction have become one of the strongest voices of The Times. Artificial intelligence (AI) technology could help the oil and gas industry find ways to drastically reduce carbon dioxide (CO2) and other greenhouse gas emissions if it wants to survive in the second half of the 21st century. Grim situation in emission reduction According to a report on the impact of atmospheric CO2 on climate change released by the US National Oceanic and Atmospheric Administration in August 2020, global CO2 concentrations, mainly caused by fossil fuel burning, rose to about 410 parts per million (one part per million) in 2019, the ...

 As scientists work to improve the strength and durability of concrete, it is perhaps not surprising that the "wonder material" graphene is proving to be a promising additive. As the world's strongest man-made material, it may have a lot to offer the construction community, and this latest example comes from researchers at Northwestern University, who have developed a new graphene-filled cement that is highly water-resistant and crack resistant. As a key ingredient in the production of concrete, the world's most widely used material, cement has a huge environmental footprint, accounting for about 8% of global greenhouse gas emissions. The researchers hope to reduce this burden by developing concrete forms that last longer, thereby reducing the need for further concrete to replace damaged structures. One of the reasons concrete structures fail is the formation of cracks, which begin as small cracks. Once water seeps into these breaks, it causes them to grow in size unt...

 Women, in their late 30s, unmarried, still living as they please. Studied medicine, psychology, photography... Moving in and out of different fields, being curious about everything and just being able to do it right, being able to do it well for a short time in any direction if you're willing to put in the effort, but it doesn't seem to stick; Boyfriends change from one to another, but they are always serious. However, they are always unable to overcome the time wasting and attraction of new love. They also make a quick decision to abandon the old love and run to new love. Nordic director Joachim Till made a film called the Worst Person in the World, and the worst person in the film is Yulia. As the last film in the director's "Oslo trilogy", this film continues the usual cold tone, still set in the streets of the Oslo Peninsula, tells a warmer and cleaner Nordic woman's story of self-exploration. Perhaps influenced by its title, the film has been interpreted...
