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

An organometallic cocatalyst helped produce ammonia by electrolysis

Chemists from the USA have found a cobalt-based cocatalyst, which, together with a tungsten-based catalyst, makes it possible to effectively produce ammonia from nitrogen under electrolysis conditions. Thanks to this combination of catalysts, the process was able to be carried out at a relatively high potential of −1.35 volts and with a current efficiency of… Continue reading An organometallic cocatalyst helped produce ammonia by electrolysis

Age and laziness increased the risk of developing cognitive dysfunction in dogs

Scientists from the USA have found out what is associated with the development of cognitive dysfunction in dogs. They included age, low level of physical activity, and a history of eye and ear diseases as risk factors. It turned out that lazy dogs risk almost 6.5 times higher than active dogs. The results of the… Continue reading Age and laziness increased the risk of developing cognitive dysfunction in dogs

Physicists simulated militant Redditors with GameStop shares

European physicists used a large amount of data from the r/wallstreetbets subreddit, as well as the dynamics of securities prices, to understand the mechanisms of self-organization of a large number of people using the example of the scandal surrounding the unexpected rise of GameStop shares. The mathematical model they developed of a voter under the… Continue reading Physicists simulated militant Redditors with GameStop shares

Ecuadorian recreates 16th-century Franciscan beer

A bioengineer from Ecuador said he managed to make beer using the same recipe as the Franciscan monks of the 16th century. To do this, he studied scientific literature and also cultivated baker's yeast, a sample of which he managed to find in an old barrel from the brewery. This was reported by France 24… Continue reading Ecuadorian recreates 16th-century Franciscan beer

Physicists have obtained a flattened Wigner crystal

American physicists reported that they saw signs of an anisotropic Wigner polycrystal in aluminum arsenide films. To enhance the effect, physicists applied additional mechanical stress along one of the directions. Scientists judged the compression of the Wigner crystal by the anisotropic behavior of the differential resistance. The study was published in Physical Review Lettersbriefly reported… Continue reading Physicists have obtained a flattened Wigner crystal

The gravitational constant was measured using bending vibrations of metal beams

Swiss physicists have experimentally implemented a new way to measure the gravitational constant. They measured the amplitude of the bending vibration of a receiver beam suspended adjacent to a transmitter beam. The vibrations of the transmitter created a variable gravitational force, which caused the receiver to vibrate. Despite the large errors, the method has the… Continue reading The gravitational constant was measured using bending vibrations of metal beams

Rosetta found naphthalene on comet Churyumov-Gerasimenko

Planetologists, while analyzing observational data from the Rosetta station for the coma of comet Churyumov-Gerasimenko, discovered more than 40 organic molecules in it, including previously undetected ones, such as naphthalene and nonane. This suggests that the process of transport of organic substances from the interstellar medium to small bodies is much more complex and larger-scale… Continue reading Rosetta found naphthalene on comet Churyumov-Gerasimenko

Physicists solved the problem of the flight of a grappling hook

American physicists examined in detail the problem of the vertical flight of a grappling hook with a rope tied to it. They not only showed that the corresponding equation of motion can be derived within two different approaches, but also solved it analytically and numerically. Calculations have shown that the rope greatly reduces the degree… Continue reading Physicists solved the problem of the flight of a grappling hook

Chemists have obtained a monolayer of polymer fullerene

Chemists from China have synthesized a monolayer of polymer fullerene, a carbon modification consisting of closed carbon polyhedra. The monolayer turned out to be a stable crystalline semiconductor with anisotropic properties. The study was published in the journal Nature. Chemists study two-dimensional carbon materials because they often exhibit unusual electronic and optical properties. This occurs… Continue reading Chemists have obtained a monolayer of polymer fullerene
