Astronomer Frank Drake dies

On Friday, September 2, 2022, at the age of 93, American astronomer Frank Drake, who became one of the pioneers of the search for radio signals from extraterrestrial civilizations, died. He is also one of the creators of the records for the Pioneer and Voyager probes and the Arecibo radio message, according to the SETI… Continue reading Astronomer Frank Drake dies

Bushfire smoke raised temperatures in Australia by three degrees

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

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

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

Astronomers have limited the lifetime of the first “intra-Venus” asteroid

Astronomers presented the results of studies of the recently discovered asteroid Ailohchahnim, whose orbit lies entirely within the orbit of Venus. It turned out that the body has a diameter of 1.7 kilometers, it can be classified as a silicate asteroid and in 1-2 million years it can collide with the inner planets or even… Continue reading Astronomers have limited the lifetime of the first “intra-Venus” asteroid

The Event Horizon Telescope saw the bend of the distant blazar's jet

The Event Horizon Telescope (EHT) has captured the most detailed image yet of the interior of the relativistic jet blazar J1924-2914, whose light took 3.5 billion years to reach Earth. It turned out that as it moves away from the core, the jet begins to bend, and toroidal magnetic fields can act in the region… Continue reading The Event Horizon Telescope saw the bend of the distant blazar's jet

“James Webb” for the first time reliably found carbon dioxide in the atmosphere of an exoplanet

The James Webb Infrared Space Observatory has for the first time reliably detected carbon dioxide in the atmosphere of an exoplanet. The target of the observations was the hot Saturn WASP-39b, and their results will help test models for the formation of the exoplanet. A preprint of the work was published on arXiv.org. Carbon dioxide… Continue reading “James Webb” for the first time reliably found carbon dioxide in the atmosphere of an exoplanet
