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
British climatologists studied the distribution of smoke in the stratosphere after bushfires in Australia in 2019–2020. They found that black carbon particles in the smoke increased the average temperature in the lower stratosphere by 0.7 degrees worldwide, with temperatures rising by three degrees over Australia. Additionally, the reaction of smoke and ozone has caused the… Continue reading Bushfire smoke raised temperatures in Australia by three degrees
Low-temperature phase transitions in ferromagnets are characterized by destruction of the domain structure. In an article in Nature physicists write that for a theoretical description of the dynamics of such transitions, it is necessary to take into account not only microscopic, but also mesoscale symmetry. This discovery indicates the possibility of the existence of non-classical… Continue reading Physicists have proven the importance of the mesoscale for quantum phase transitions
Archaeologists explored the ancient settlement of Red October-1, located in Taman. As a result of this work, they established that the fortified settlement arose at the turn of the 6th–5th centuries BC and existed until the modern era. Among the rare artifacts discovered at this site were a gray clay lamp in the shape of… Continue reading Archaeologists have discovered a bronze figurine of Jupiter in Taman
Scientists from the USA and Cyprus have found that the gender of the experimenter can influence the results of medical experiments on mice. It turned out that the smell of men causes stress in animals and a desire to escape from its source. But if a man injects a mouse with an antidepressant, its effect… Continue reading The smell of a woman prevented an antidepressant from calming mice
Astronomers from six countries have confirmed the idea that supernova SN 1181 AD, which exploded in 1181, represents the second remnant of a rare type of Iax supernova confirmed in the Milky Way. It is assumed that two carbon-oxygen white dwarfs or a massive carbon-oxygen dwarf with a helium companion merged without the resulting white… Continue reading Supernova 1181 fits the model of the merger of two white dwarfs
Archaeologists have discovered fragments of frescoes during excavations of the 2,000-year-old Temple of Cupra in the Italian commune of Cupra Marittima, CNN reports. They are made in the third Pompeian style. Surviving interior frescoes of this kind are rare. Cupra Marittima, due to its location on the Adriatic coast, was an important port city and… Continue reading Archaeologists have found well-preserved fragments of Roman frescoes from a 2,000-year-old temple
Researchers from the United States have found out how different methods of insulin administration affect brain development in adolescents with type 1 diabetes. Typically, this disease causes changes in the structure of the brain and leads to a decrease in cognitive abilities. But as it turned out, those who used an advanced insulin pump (which… Continue reading Insulin pump restores brain structure in diabetic teenagers
Spanish archaeologists discovered a bas-relief depiction of a phallus during excavations at El Higuerón in southern Spain. It was carved on the cornerstone of a large ancient Roman building that scientists are exploring in Nueva Carteya in the province of Cordoba, El Pais reports. Phallic symbols and images were widespread in ancient Rome. They were… Continue reading In Spain, a half-meter-long ancient Roman phallus was found carved on a building.
Biologists have found out who should be blamed for the environmental disaster caused by rabbits brought to Australia. Genetic analysis has shown that almost the entire local population of these animals descends from 13 wild and domestic individuals and their descendants, which were received from England in 1859 and released on his estate by settler… Continue reading A 19th-century English farmer was accused of invading Australia by rabbits.
