And is there a creature on Earth, other than primates, that could develop civilizational capabilities? Is it the wolf, which is famous for its social nature, or the dolphin, which is known for its high intelligence? However, today, 009 will bring you a completely different answer.

Everything in the universe is fixed in an endless cycle, researchers: is there something else about the origin of the universe?
We have always had an unresolved confusion - where did the universe come from? And where did we humans come from? Although we are scientists to come up with "evidence" to tell the universe from the singularity of the big bang, and human evolution from the ape, not all people on earth believe the scientist's "testimony". Those places with ancient cultural heritage would rather believe that the universe and human beings were created by "God" than believe the scientific explanations of scientists.

Why did Soviet fertility fall off a cliff after World War II? Because of a bleak economic outlook and uncertainty
After World War II, the Soviet birth rate declined steadily until the date of its dissolution. Among them, there was a precipitous decline from 1960 to 1970, when the total fertility rate fell from 2.49 to 1.7, below the level of natural population replacement.

The "water monster" that appeared 3 times in 100 years was found in the belly of a whale, do they really exist?
Exploring the unknown is always one of the human curiosity, and the endless sea has made explorers and scientists swoon. After decades of research and investigation by marine workers, marine organisms have been identified and lists have been compiled, and there are about 15,304 species of marine fish registered, with a pre-estimate of about 20,000 species of marine fish.

To date, the most complete map of human cells has been released; plants have been planted on lunar soil for the first time | Global scientific news
The most complete map of human cells has been released so far. Today, Science magazine published four papers simultaneously, publishing the most comprehensive pan-tissue human single cell map constructed by scientists of the International Union of Human Cell Atlas. This map, which contains 33 human tissues, more than 1 million cells and more than 500 cell types, provides extremely important insights into common and rare diseases, vaccine development, anti-tumor immunity and regenerative medicine.

This kind of goose was once an endangered species, but now people have to give them family planning again.
Originally a migratory bird, the goose migrates back and forth between Canada and the United States every year, thanks to its huge size (wingspan 1.27 to 1.85 meters, weight 2.6 to 6.5 kilograms) and its natural aggressiveness, it has few natural enemies in adulthood, only hyenas, gray wolves, golden eagles, sea eagles, snow owls and so on. As a result, their original habitat is so vast that they can be seen from northern North America to areas close to Central America.

Spooky photos were taken on Venus, and moving objects appeared on the surface, causing a stir in the scientific community
The eight planets in our solar system are unique in appearance and size, and although Earth is not the largest one, it is one of the most special because this planet has land and oceans on its surface, and there are also many green areas on the land, a feature that the other planets do not have. At one time, Venus was seen as a sister planet to Earth because the two are more similar in many ways. For example, Venus has 0.82 times the mass of Earth, 0.95 times the radius of Earth, and 0.9 times the gravity of Earth.

Deng Hongkui's team of Peking University uses chemical reprogramming to completely reverse the "developmental clock" of human cells. | Global scientific news
Cell biology? Chemical reprogramming reverses the "developmental clock" of human cells Cell reprogramming can transform one cell into another type of cell, such as using oocyte cytoplasm or transcription factors, to reprogram somatic cells into pluripotent stem cells. In addition, exposure to an environment containing some small molecules (chemical stimulation) can also change the fate of cells, but it is more difficult to achieve in human cells. In a new study published in Nature, a team led by Deng Hongkui, a professor at Peking University, induced human cells into an intermediate state of plasticity, realizing the chemical reprogramming of human body cells.

The existence of dragons is not scientific? Yet science cannot completely deny its existence?
Dragons have always been magical creatures that exist in mythology, from ancient mythology to historical records, and even in recent times, there have been records of dragons being found. Are we Chinese also call ourselves the heirs of the dragon, so is the dragon a real creature or not? Many people speculate that the dragon is our Chinese totem, which was made by splicing different parts of the enemy totem during ancient wars. This seems to explain very well why dragons have a lot of divinity. Therefore, there is a view that the dragon is a fictional creature. Some even believe that the characteristics of dragons, such as the ability to go up in the air, make clouds and rain, and breathe fire, defy science. This makes it even more certain that the dragon is just a fictional totem beast.

May reappearance of unidentified flying objects? The International Space Station photographed the glowing object, and the spacecraft brushed by
According to a report on May 7, 2021, a UFO hunter Grahame claimed to have seen a mysterious unidentified glowing flying object in space in the live feed from the International Space Station. The Russian cargo ship was delivering food, water, fuel, and other supplies to the ISS at the time, and as the ship was preparing to dock with the ISS, the mysterious glowing object flew quickly past the ship and disappeared into space after flying at high speed toward the cargo ship. After a few seconds, this one unidentified luminous object returned with almost the exact same flight path. At that time this one image was shared on the social platform, which triggered a lot of enthusiasts' hot discussion and speculation.
