 Ancient viruses shaped our brains Our developed brain, the damage to viruses, especially in mammals, amphibians and fish, myelin additional) makes itself easier) owes its name to a retroviral element called "Retromelin" that plays a major role in the production According to the study, the discovery of myelin, a key factor in the evolution of the nervous system of hopeful vavonons, was facilitated by the recombination of viruses into the genome. Observing the presence of retromyelin in species and helping to treat its major role in protective myelination is not only elucidating the molecular mechanisms of myelin development, but also influencing elements in vertebrate evolution.

 A theory in science is a logical product. Based on relatively accurate experimental data, it serves for a deeper understanding of the laws of nature and the universe. However, a scientific theory may not always reflect the absolute truth. The truth is that a particular current scientific theory of the present time only represents the totality of our current knowledge. The real truth may turn out to be completely different, and it is possible that we just lack our knowledge. A scientific discovery can completely disprove a certain scientific theory and force scientists to start all over again. One such example is the development of human knowledge about the solar system As you know, in the second century AD, the Greek philosopher Ptolemy put forward the theory that the Earth is at the center of the universe and that the Sun, Moon and other planets revolve around the Earth. It was the simplest astronomical observation of the time and a satisfactory theory for social consciousness in...

  The chip works for the human brain 🧠  The first person with a Neuralink chip implanted in his brain wrote a tweet with the power of thought Earlier, he had pushed the pieces along the chessboard on the laptop screen with the power of his mind. The first patient with a Neuralink chip implanted in his brain wrote his first post on the social network X (formerly Twitter) using the power of thought. Neuralink and X company owner Elon Musk informed them about it. "The first post written with the power of thought using the Neuralink telepathy device!" wrote billionaire and patient Nolan Arbo, pointing to a post on his page. "Twitter banned me as a bot, but Elon Musk restored the page," the patient wrote in a message. Nolan Arbo, 29, was paralyzed from the shoulders down after an accident eight years ago. On January 28, neurotechnology company Neuralink implanted a neurochip in his brain for the first time. With the help of a Neuralink implant called telepathy, he can a...

  A cow has been created that produces enzymes for human insulin in its milk     In a new study, the production of "human" insulin was achieved for the first time in the milk of genetically modified cows. Scientists from the University of Illinois, Urban-Champaign, USA, placed a specific segment of human DNA that encodes proinsulin (a protein that turns into insulin) into the cell nuclei of 10 cow embryos. The embryos were then placed in the stomachs of normal cows. A transgenic calf (female) was successfully delivered in one case   After the genetically modified cow grew up, many attempts were made to artificially inseminate it, in vitro fertilization, and even old-fashioned impregnation. None of them were successful. Eventually, milk was produced using cow hormone therapy. Although she gave little milk, mass spectrometry showed that it contained C-peptide, an enzyme in such cow's milk that can convert "human" proinsulin into insulin. x

 Facts about the human body: From atoms to the Andromeda galaxy - Man is made up of approximately 7,000,000,000,000,000,000,000,000,000 (7 octillion) atoms, each billion years old. For comparison, our galaxy has about 300 billion stars - Most of the atoms that make up our body consist of space. The nucleus at the center of the atom is so small that it is the size of a golf ball in a football stadium. - The atoms that makeup matter are never intertwined. The closer they are to each other, the more their component charges are repelled. It is like trying to bring together the ends of two strong magnets with the same charge. For example, when you sit on a chair - you do not "touch" it. You stand a certain distance from the chair due to the repulsive force on the atoms. - Everything we feel is made of molecules. The largest molecule in nature is the first chromosome in our body. The largest known molecule at the moment is DNA, the first human chromosome. It holds about 10,000,000...

 What is Astronomy? Astronomy is the study of our universe beyond Earth. Everything we know about the sun, moon, planets, stars and much more comes from astronomy. Astronomers use mathematics, physics, and chemistry, as well as their signature tool, the telescope, to understand our universe. The first modern astronomer was the Polish scientist Nicolaus Copernicus. Known as the father of astronomy, Copernicus proposed in 1532 that the Earth revolves around the sun. This was the opposite of the long-held belief that everything in space revolved around the Earth. Although true, Copernicus's theory was not proven until 1632 when the Italian astronomer Galileo Galilei proved that the planets revolved around the sun. He made this revolutionary discovery using a telescope and was the first person to use it to explore the universe. In the centuries since Copernicus and Galileo, astronomers have continued to make amazing discoveries, from black holes to Jupiter's moons. They also put fo...
