The first South Korean lunar probe sent the first photo of the Earth and the Moon

The Danuri probe, which became South Korea's first lunar probe, sent back to Earth the first image of the Earth and the Moon. Thus, engineers confirmed the functionality of the camera, which examined the far side of the Moon from an unusual distance, according to the website of the Korean Astronomy and Space Science Institute… Continue reading The first South Korean lunar probe sent the first photo of the Earth and the Moon

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

MOXIE received 50 grams of oxygen from the Martian atmosphere in 9 hours

The team of the MOXIE experiment to obtain oxygen from the Martian atmosphere presented the results of its work on Mars for 2021. The device installed on the Perseverance rover worked for a total of almost 9 hours, during which time it generated 50 grams of oxygen suitable for human use. Thus, on the basis… Continue reading MOXIE received 50 grams of oxygen from the Martian atmosphere in 9 hours

NASA has fixed a glitch in Voyager 1's telemetry sending system.

The Voyager 1 team solved the problem of sending anomalous telemetry that had been coming from the probe for several months. It turned out that the cause of the failure was a faulty on-board computer, which was mistakenly assigned the operation of sending data. The problem has now been fixed, according to NASA's website. Voyagers… Continue reading NASA has fixed a glitch in Voyager 1's telemetry sending system.

Ancient Tarim people were found among the ancestors of modern inhabitants of the Pamirs

Geneticists investigated the origins of speakers of Turkic and Indo-European languages ​​from Central Asia, for which they sequenced the DNA of 131 people and combined the data obtained with previously published ancient and modern genomes. It turned out that the origin of the Kyrgyz can be modeled from two components: the population of Xinjiang of… Continue reading Ancient Tarim people were found among the ancestors of modern inhabitants of the Pamirs

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

Evolution forced mammals to recreate salivary proteins fifteen times

American bioinformaticians have discovered traces in the genomes of mammals of 15 independent occurrences of new proteins responsible for the viscosity of saliva. According to the findings of the authors of a study published in Science Advancesthe culprit is a region of the genome with a high mutation rate and selection pressure during the evolutionary… Continue reading Evolution forced mammals to recreate salivary proteins fifteen times

The population of the ancient Carthaginian city turned out to be genetically diverse

Paleogeneticists have read 30 genomes of ancient inhabitants of Tunisia, central Italy and Sardinia dating back to the Iron Age. In all regions, they found both descendants of more ancient local populations and immigrants from other territories. Thus, in the necropolis near the Carthaginian city of Kerkuan there were the remains of the descendants of… Continue reading The population of the ancient Carthaginian city turned out to be genetically diverse

Insulin pump restores brain structure in diabetic teenagers

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

Paleogeneticists read the genome of the “warrior with a griffin” from Nestor’s palace

Paleogeneticists have studied the origins of populations whose history is known from written sources. They discovered that the Mycenaeans arose from the mixing of Minoans and migrants whose origins were connected with the Eurasian steppe. However, the famous “warrior with a griffin,” whose rich burial was found in Pylos several years ago, did not have… Continue reading Paleogeneticists read the genome of the “warrior with a griffin” from Nestor’s palace
