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

Physicists have reproduced the chirping effect at the Kukulcan Pyramid

Colombian physicists have reproduced the unusual acoustic effect observed at the Temple of Kukulcan, located on the Yucatan Peninsula in Mexico. The echo of hand clapping at the base of the pyramid resembles the chirping or chirping of a bird. Simulations showed that this effect occurs due to the addition of many waves reflected from… Continue reading Physicists have reproduced the chirping effect at the Kukulcan Pyramid

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

Physicists have proven the importance of the mesoscale for quantum phase transitions

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

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

Ingenuity survived the Martian winter

The Martian drone Ingenuity made its first full flight after two months of inactivity, thereby confirming that it successfully survived the coldest part of the Martian winter. In the near future, the drone will receive a software update and will go to explore the delta of the ancient river in the Jezero crater. reported on… Continue reading Ingenuity survived the Martian winter

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

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 return of bison has made the prairie vegetation more diverse

The reintroduction of bison to areas of the prairie where they once lived but were exterminated by humans has a positive effect on the local flora, American ecologists have found. After analyzing the results of an experiment lasting about thirty years, they found that in the presence of bison, the species diversity of prairie plants… Continue reading The return of bison has made the prairie vegetation more diverse
