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.

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.

After 7 months in space, the U.S. Trailblazer went to work, and China's Tianwen-1 is doing
On March 10, 2021, NASA revealed the work of its fifth Mars rover, Trail, on Mars, 170 million kilometers away from Earth. The "Mars rover", which is about the size of a typical family SUV, has already begun taking close-up photos of rocky targets on Mars that it has targeted.

How long has it been on Earth since we left at the speed of light and returned at the speed of light a year later?
If an astronaut leaves Earth at the speed of light and returns at the speed of light a year later, by common sense, two years should have passed on Earth by the time the astronaut returns.

Study finds that sharks use Earth's magnetic field to guide them like a map
Sea turtles are known to rely on magnetic signals to find their way across thousands of miles to the beaches where they hatch. Now, in the May 6 issue of Current Biology, researchers report some of the earliest conclusive evidence that sharks also rely on magnetic fields for long-distance trans-oceanic voyages.
