Poor protein utilization contributes to neurodegeneration

Neurodegeneration can occur more quickly if nerve cells lack retromer proteins, which are responsible for breaking down toxic tau protein. This conclusion was reached by scientists who observed genetically modified fruit flies that produced human tau protein in 39 neurons of the eye. Tau protein itself already caused the death of nerve cells, and the… Continue reading Poor protein utilization contributes to neurodegeneration

Ornithologists have described a new bird species from the subantarctic islands

Ornithologists have described a new species of bird that lives on the Diego Ramirez Islands south of South America. It is called the subantarctic rayadito. In the past, the local population was thought to be the spiny-tailed rayadito, which is widespread in Chile and Argentina. However, the analysis showed that individuals from the Diego Ramirez… Continue reading Ornithologists have described a new bird species from the subantarctic islands

The water level in the Nile allowed the Egyptians to transport stone to the site of the pyramids.

At the time of the construction of the Giza pyramids, the water level in the Nile allowed the filling of an artificial reservoir near the construction site so that the Egyptians could transport materials from the quarries directly to the construction site. This was confirmed by scientists from Egypt, China and France, who examined sediment… Continue reading The water level in the Nile allowed the Egyptians to transport stone to the site of the pyramids.

Analysis of 777 ancient genomes clarifies the origins of paleometal populations

Paleogeneticists analyzed 777 ancient genomes from Anatolia, southeastern Europe and western Asia, spanning the last ten thousand years of human history. Focusing on the Palaeometallic Age, scientists found that there was no gene flow from Europe to Anatolia during the entire Bronze Age. In addition, they clarified the influence of representatives of the Yamnaya culture… Continue reading Analysis of 777 ancient genomes clarifies the origins of paleometal populations

Archaeologists have found a bronze cheekpiece in the Borre style in Novgorod

Archaeologists discovered a rare bronze cheekpiece made in the Scandinavian Borre style in the Trinity excavation site in Veliky Novgorod. The artifact was found during a study of cultural layers of the first half – mid-10th century. This was reported in a press release from Moscow State University. In 1932, the famous Russian scientist Artemy… Continue reading Archaeologists have found a bronze cheekpiece in the Borre style in Novgorod

Planetologists have confirmed the possibility of delivering volatile substances to the young Earth by asteroids

Planetologists presented new results from analyzing soil particles from the Ryugu asteroid in laboratory conditions. It turned out that the temperature inside Ryugu’s parent body could not exceed 30 degrees Celsius, and asteroids like Ryugu could indeed deliver volatile substances to the young Earth. Article published in the magazine Nature Astronomy.The near-Earth 900-meter asteroid Ryugu,… Continue reading Planetologists have confirmed the possibility of delivering volatile substances to the young Earth by asteroids

Onions that melted in Norway turned out to be about 4,000 years old

Archaeologists have radiocarbon dated a wooden bow discovered last year in Norway. It turned out that the artifact that melted from under the ice was about four thousand years old. According to researchers, this is the oldest bow ever found in Norway, as they reported on the Secrets of the Ice project Facebook page*. Climate… Continue reading Onions that melted in Norway turned out to be about 4,000 years old

Physicists have implemented optical stochastic cooling of particle beams

American physicists reported that they were the first to realize optical stochastic cooling of beams of charged particles. This type of cooling consists of damping pulse fluctuations through a feedback system. In the new work, this communication occurred at optical frequencies, which is necessary to increase the efficiency and cooling rate of accelerators and synchrotrons.… Continue reading Physicists have implemented optical stochastic cooling of particle beams

A new sauropod from Colombia reveals the early spread of long-necked dinosaurs to South America

A new species of giant, long-necked dinosaur that lived about 175 million years ago during the Jurassic period was described in Colombia. Vertebra belonging to Perijasaurus lapaz, is the earliest and northernmost sauropod specimen discovered in South America. The find provides information about the initial diversification of sauropods at low latitudes. The study was published… Continue reading A new sauropod from Colombia reveals the early spread of long-necked dinosaurs to South America

Archaeologists have found European dishes and shoes at the Novgorod German Court

Pyotr Gaidukov from the Institute of Archeology of the Russian Academy of Sciences spoke about the results of excavations of the German Court in Veliky Novgorod. When studying the cultural layers of the 13th–14th centuries, researchers found more than two thousand objects, among which were lead commercial seals, ceramic and wooden dishes and other household… Continue reading Archaeologists have found European dishes and shoes at the Novgorod German Court
