Chemists have found ideal conditions for the hydrogen borrowing reaction

Chemists from Russia studied the hydrogen borrowing reaction necessary for the formation of carbon-nitrogen bonds. They found that it often does not require a catalyst at all, and also developed recommendations for successfully carrying out the reaction in the laboratory. The study was published in the journal Journal of Catalysis. Organic compounds containing an NH… Continue reading Chemists have found ideal conditions for the hydrogen borrowing reaction

Paleogeneticists have confirmed the Ugric origin of the Hungarians

Paleogeneticists read 271 genomes to find out the origins of the Huns, Avars and Hungarians who found themselves in the Carpathian Basin in the 5th–9th centuries AD. They discovered continuity between the Asian Xiongnu and the European Huns, and also confirmed the origin of the Avars from the territory of modern Mongolia. In addition, scientists… Continue reading Paleogeneticists have confirmed the Ugric origin of the Hungarians

Alpine blacksmiths of the Iron Age feasted on hazel and bird cherry fruits

Austrian paleobotanist Marlies Ausserlechner examined materials collected during excavations of an Iron Age Alpine forge (circa 368–36 BC) to understand the diet of ancient metallurgists. It turned out that they ate cereals and legumes, meat, as well as edible fruits of wild plants, such as hazel or bird cherry. According to the researcher, the diet… Continue reading Alpine blacksmiths of the Iron Age feasted on hazel and bird cherry fruits

NASA rolled out the SLS super-heavy rocket onto the launch pad for the first time

NASA for the first time rolled out the SLS super-heavy rocket, which will send astronauts on lunar missions, to the launch pad at the Cape Canaveral spaceport. The first flight of the rocket is expected to take place in the summer of 2022. SLS is a promising super-heavy rocket that NASA plans to use for… Continue reading NASA rolled out the SLS super-heavy rocket onto the launch pad for the first time

Escape from the genome

Inheriting DNA from parents is not the only way genetic information is passed on. Even in the human genome you can find sections that were inherited by human ancestors from completely different, unrelated species of animals, and not only animals. Biologists constantly encounter traces of horizontal gene transfer in the genomes of different organisms. Viruses… Continue reading Escape from the genome

“Culture. Literature. Folklore”

Urban superstitions, jokes and children's horror stories are as important a part of folklore as fairy tales and epics. But they began to be collected and studied relatively recently, only since the late 1980s. The first who drew attention to this part of the culture – and thereby laid the foundation for a new direction… Continue reading “Culture. Literature. Folklore”

“Consumption Society: Humanity's Search for Food”

About 10 thousand years ago, we purposefully raised plants and animals. The development of agriculture led to major inventions, social stratification, economic inequality and war. In the book “The Consumption Society: Humanity in Search of Food” (Alpina Non-Fiction Publishing House), translated into Russian by Natalia Kolpakova, journalist and writer Mark Bittman explains how the desire… Continue reading “Consumption Society: Humanity's Search for Food”

“Oh wonderful perishable world”

Under normal circumstances, we rarely encounter death in person and are much more likely to encounter it in books, movies, and video games. However, for some people, dealing with someone else's death is routine. In the book “O wondrous perishable world. When death is the business of life” (publishing house Mann, Ivanov and Ferber), translated… Continue reading “Oh wonderful perishable world”

Non-Markovian heat exchange with the reservoir explained the Mpemba effect

Chinese physicists have shown numerically and analytically that the Mpemba effect can arise due to the non-Markov interaction of the system with the reservoir. To do this, they simulated the heat exchange between the reservoir and the chain of spins and showed that the energy barrier that appears on the way of cooling of the… Continue reading Non-Markovian heat exchange with the reservoir explained the Mpemba effect

Borrow from nature

The human brain is the most complex and efficient computing system, and recreating human intelligence has been one of humanity's greatest goals of all time. Today, Rosatom engineers, together with scientists, are working on the creation of neuromorphic (that is, borrowing approaches from biology) artificial intelligence systems. But aren’t neural networks already neuromorphic in themselves?… Continue reading Borrow from nature
