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

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

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

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

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

James Webb finds organic molecules in icy particles around a very young protostar

The James Webb Infrared Space Telescope has reliably discovered a number of organic molecules, including complex ones, in the composition of ice particles in the core of the very young protovesche IRAS 15398−3359. In addition, the telescope examined the structure of one of the outflows of matter from the protostar, which consists of four shells.… Continue reading James Webb finds organic molecules in icy particles around a very young protostar

Metasurfaces emit entangled photons with variable wavelengths

American and German physicists have fabricated thin metasurfaces consisting of arrays of silicon nanocavities that exhibit spontaneous parametric scattering. They showed that such structures are capable of generating entangled photons. Unlike traditional media used for this, metasurfaces have greater flexibility, which allows the wavelength of the resulting photons to be changed by changing the pump… Continue reading Metasurfaces emit entangled photons with variable wavelengths

Playing music in childhood has been linked to long-term improvements in cognitive abilities.

Playing a musical instrument in childhood and adolescence is associated with improved cognitive skills in later life, British researchers have found. The positive effect persisted even after adjusting for several factors, such as childhood environment. The study was published in Psychological Science. Developed cognitive skills can influence academic and professional achievements, as well as health.… Continue reading Playing music in childhood has been linked to long-term improvements in cognitive abilities.
