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

Hormone injections improve cognitive performance in Down syndrome

Injections of a hormone from the hypothalamus, which is responsible for the development of the genital organs and is commonly used to treat infertility, have been able to improve cognitive performance in people with Down syndrome. This was discovered by European scientists who conducted a study on seven young men. After six months of living… Continue reading Hormone injections improve cognitive performance in Down syndrome

Physicists were able to obtain acoustic frequency combs at 10 gigahertz

American physicists have manufactured a hybrid system from a nonlinear oscillatory circuit and an acoustic resonator connected by a piezoelectric contact. This combination made it possible to impart nonlinearity to acoustic modes at a frequency of 10 gigahertz. The authors were able to generate coherent acoustic frequency combs in their setup, which will help combat… Continue reading Physicists were able to obtain acoustic frequency combs at 10 gigahertz

A burial of a woman from the Koban culture with a bronze mirror was found in the Stavropol region

Archaeologists have discovered the grave of a woman 20–25 years old in the north-west of the Stavropol Territory. The accompanying grave goods and funeral rites made it possible to attribute this find to the Western Koban culture and date it to the second half of the 8th century BC. Among the artifacts found, scientists identified… Continue reading A burial of a woman from the Koban culture with a bronze mirror was found in the Stavropol region

Archaeologists have discovered a bronze figurine of Jupiter in Taman

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

Ozonation of the air caused the skin to create an oxidative field around a person

Chemists from Germany, the USA and Denmark have found that substances secreted by human skin lead to the formation of an oxidative field around it. Scientists placed four people in a sealed mock-up office and began ozonizing the air to a level close to the maximum permissible concentrations. The experiment showed that ozone interacts with… Continue reading Ozonation of the air caused the skin to create an oxidative field around a person

Traces of cockroach ootheca found in Jomon period ceramics

Archaeologists have examined 4,000- to 5,300-year-old Jomon period pottery discovered in Japan. In five artifacts they found traces of cockroach ootheca. One of them was laid by Japanese cockroaches (Periplaneta japonica), the rest look like smoky cockroaches (P. fulinginosa). Previously, it was believed that the latter species was brought to Japan only in the 18th–19th… Continue reading Traces of cockroach ootheca found in Jomon period ceramics

Compression socks protected the intestines of marathon runners from damage

Australian sports doctors, with the participation of fifty runners, studied how compression socks affect the effects of running on the digestive system. After the marathon, those who ran in knee socks had lower levels of a protein marker of small intestinal damage. In an article published in The Journal of Strength and Conditioning Researchthe authors… Continue reading Compression socks protected the intestines of marathon runners from damage

Tea drinking linked to reduced risk of death from all causes

American researchers have found that drinking tea is associated with a decrease in mortality from all causes, and also found a relationship with a decrease in the likelihood of death from cardiovascular diseases, coronary heart disease and stroke. The results of a survey and medical examination of half a million Britons aged 40 to 69… Continue reading Tea drinking linked to reduced risk of death from all causes

Daily inhalation of laughing gas left the patient unable to walk

American doctors described in The New England Journal of Medicine rare medical case. A patient was admitted to the hospital with symptoms of severe vitamin B deficiency.12 – impaired sensitivity and coordination of movements, up to the inability to walk. It turned out that over the past two months he had been inhaling nitrous oxide… Continue reading Daily inhalation of laughing gas left the patient unable to walk
