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.

Don't look for extraterrestrial civilization, there is one within the Earth, scientists: in front of it human is a higher civilization
In the wilderness of the northeastern region of Brazil, there is a large colony of huge white ant nests, presumed to have existed 3,000 to 800 years ago and still in use and under construction until now. Its total area is about 228,000 square kilometers, and the mounds of earth visible on the surface exceed 200 million, which can even be photographed in outer space. By no coincidence, there is a giant red ant 1 on the seashore of Hokkaido The colony contains more than 300 million worker ants and 1.08 million queens, which live in 45,000 interconnected crypts that spread over an area of 27,000 square kilometers.

If the Creator wanted to leave some message for humans, where would the message board be?
Scientists want to know if the existence of our universe was deliberately created and have tried to prove it through some scientific studies. However, so far it is not conclusive whether a creator exists or not.

Human life expectancy is determined at birth? Research shows that basic life expectancy depends on genetics
The topic of life expectancy, from ancient times to the present is a common concern of all people, although, with the continuous progress of medical level, the average life expectancy of human beings has been extended to a certain extent, in the natural state, the length of life of different people n there is still a great difference. It is for this reason, to completely uncover the hidden secrets of human life span, scientists are also constantly working on research.

500 million-year-old trilobite fossil, human footprints found, who actually wore shoes to the bottom of the sea?
Although the Earth now looks prosperous, but this is only the result of the Earth's evolution and development of 4.6 billion years, because the birth of the Earth to now, has been 4.6 billion years, and nurtured countless species of organisms.
