Our eyes are tuned only to a narrow band of possible wavelengths of electromagnetic radiation, on the order of 390-700 nanometers

Chinese scientists, who recently presented a project for the world's largest "clone factory", announced their readiness to clone people. The only obstacle to this, according to the Chinese, is - public reaction

Experimental physicians from the Queensland Clinic believe that in the not too distant future men will have a unique opportunity to bear and give birth to children

Everyone has heard of submarines, and everyone knows them well. But not everyone knows about underground boats. But such projects existed in real life. Yes, and in the future they may return, although not a fact.The concept of an underground boat may sound strange

The duel of huge combat humanoid robots (BCH) that took place the day before made, to put it mildly, an ambiguous impression. Let's try to dig deeper and understand why this happened. What is BBR?

The Mitrailleza was created as a special type of a salvo cannon capable of conducting dense barrage of fire. The first mitrailleuse in history was invented by the captain of the Belgian army Fafchamps in 1851, but it was used much later

Soon after the end of World War II, the United States experienced a rapid growth in air passenger traffic. Airplane tickets gradually, but steadily, became cheaper, which over time allowed airlines to compete with the railways

More and more countries are abandoning the integrity of human embryos and conducting research in the field of genetic manipulation. The first scientific works from the USA and China appeared, during which modified human embryos were created. "Tape

Many residents of Beijing praised the innovation. One of the cemeteries in China has launched a VR death simulator

At the moment, no matter how capable a robotic mechanism is, in most cases it acts according to pre-prescribed algorithms (or is completely controlled by a person) and cannot foresee the consequences of its actions

In 1958, Soviet biologist Ilya Darevsky described a genus of lizards that consisted only of females. It was a major world discovery

Count off five seconds to yourself, and then look at your watch. Almost exactly, right? Perception of time - one of the biggest mysteries of the brain

According to science fiction stories, clones are never perfect copies of the original organism. And copies of clones may even turn out to be strange and even "sloppy"

Scientists from China report that they have been able to use gene editing technology for the first time to breed special dogs. They created beagles with double the amount of muscle mass by removing the gene responsible for the production of myostatin protein

The numerous health problems that killed the most famous sheep in human history do not appear to have been caused by cloning. Dolly's four clones remain healthy, almost to old age

X-rays of the bones of Dolly the sheep, her daughter and two other cloned sheep showed that they did not suffer from osteoarthritis and other forms of senile disease and did not age abnormally quickly, according to an article published in the journal Scie

Researchers from China managed to get a genetically modified sheep with a gene responsible for the production of "correct" fats

On February 22, 1997, the world learned about the existence of Dolly the sheep - the first warm-blooded animal cloned with a conventional somatic cell. How the bold technology was developed and whether it has a future

Scientists at the University of California, San Diego create a Neanderthal brain rudiment (organoid) from stem cells using DNA data from an archaic person and the CRISPR genome editing system

American biologists have developed a method for the development of germ cells with half the genetic set of somatic ones in the laboratory ("gametogenesis in a test tube"). They talked about their work in the journal Science Translational Medicine

No matter how perfect the mechanism is, sooner or later it will break. So is the human body. Gradually wearing out, it ceases to perform its tasks

Polish scientists have repeated Milgram's famous experiment on their compatriots. It turned out that the Poles of the 2010s are as willing to hurt people by submitting to authority as the Americans of the 1960s

In our world, many people still perceive video games as something frivolous. But far from it

There is a lot in nature, friend Horatio, That our sages never dreamed of. Shakespeare. Hamlet (after reading this article). Is the title of the article worthy of a madman? Right

The conquest of nature by man has not yet ended. In any case, we have not yet captured the nanoworld and established our own rules in it. Let's see what it is and what opportunities the world of objects measured in nanometers gives us. What is "nano"

The contribution of Nikola Tesla to the high-tech of the twentieth century can hardly be overestimated. All the technology of the twentieth century is built on his discoveries. It was his work that made the emergence of modern electronics possible

Japanese robotics engineers are considered to be some of the best in the world. Already somewhere, but in the Land of the Rising Sun, robots are revered more strongly than anywhere else

Each of us knows that the normal body temperature of a healthy person is 36.6 degrees Celsius. When the temperature rises to 42 degrees, the protein in the body is folded, amino acids are destroyed, brain cells die off

In 1961, the Soviet Union tested a nuclear bomb of such strength that it would be too large for military use. And this event had far-reaching consequences of all kinds
