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

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

People buried in an English well turned out to be victims of a medieval pogrom

Scientists from the UK and Germany examined the remains from a collective burial in a well, discovered in the center of Norwich, England in 2004. Radiocarbon dating showed that these people, many of whom were children, died between 1161 and 1216 AD. Paleogenetic research and historical evidence indicate that the remains belonged to Ashkenazi Jews,… Continue reading People buried in an English well turned out to be victims of a medieval pogrom

Watering with ethyl alcohol protected the rhizome from drought

Japanese geneticists have proposed increasing the drought resistance of plants using ethanol. They watered Tal's rhizomes (Arabidopsis thaliana) with a weak alcohol solution for three days and showed that this helped the plants survive the subsequent three-week drought. In response to alcohol, the plant activates the synthesis of the stress phytohormone, abscisic acid, which helps… Continue reading Watering with ethyl alcohol protected the rhizome from drought

Paleogeneticists read DNA from ancient Egyptian canopic jars for the first time

For the first time, paleogeneticists have sequenced DNA from samples of biological material extracted from ancient Egyptian canopic jars. Although the quality of reading in most cases turned out to be extremely low, in two cases scientists were able to determine the mitochondrial haplogroups of people: H and R0a1. Since they occur in both ancient… Continue reading Paleogeneticists read DNA from ancient Egyptian canopic jars for the first time

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

Archaeologists have found a 600-year-old kitchen in Moravia

Czech archaeologists have unearthed a well-preserved medieval kitchen during work in the town of Novy Jicin in the Moravian-Silesian Region. Archaeologists date the brick oven, hearth and surviving pottery to the beginning of the 15th century. Radio Prague International reports this. Novy Jicin was supposedly founded at the end of the 13th century at the… Continue reading Archaeologists have found a 600-year-old kitchen in Moravia

Solar power plant mirrors roasted chili peppers

An American engineer used light collected by the heliostats of an experimental solar power plant to roast green chilies and compared the result with the product obtained by traditional gas burner roasting. A blind tasting showed that the new method resulted in better flavor and more uniform processing of the peppers. The developed approach can… Continue reading Solar power plant mirrors roasted chili peppers

New Zealand cats caught hunting endangered bats

Zoologists have described two new cases of cats hunting endangered New Zealand bats. In one of them, a feral cat caught and ate a sheathwing in the forest, and in another, a free-roaming cat injured and killed several sheathwings near her home. As noted in the magazine article New Zealand Journal of Zoologymost likely cats… Continue reading New Zealand cats caught hunting endangered bats

Chinese chemists simulated the filtration of smoke from an ancient goose lamp

Chinese chemical technologists have discovered that an ancient oil goose lamp could filter combustion smoke and reduce indoor air pollution. The design of the lamp makes it possible to reduce by almost 17 percent the amount of smoke entering the room when burning oil. The study was published in PNAS. The painted bronze lamp was… Continue reading Chinese chemists simulated the filtration of smoke from an ancient goose lamp
