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

Ice-resistant self-propelled platform “North Pole” went on its first voyage

The research vessel North Pole has set out on its maiden voyage, the Arctic and Antarctic Research Institute said in a statement. It will carry an expedition to the Central Arctic, which will continue the research of the region begun in the 1930s. The 41st Arctic drifting polar station will continue regular research of the… Continue reading Ice-resistant self-propelled platform “North Pole” went on its first voyage

The algorithm determined the mouse's pain level based on its muzzle expression

American scientists have developed a cloud platform that can assess the severity of pain in black laboratory mice. She analyzes the expression of the animal's face – the position of its nose, ears, whiskers and the degree of squinting of the eyes. Previously, researchers coped with this task manually, but, as the results show, the… Continue reading The algorithm determined the mouse's pain level based on its muzzle expression

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

Mirror light nuclei differed from heavy ones in the frequency of nucleon pair production

Physicists from 13 countries presented the results of a study of the relative frequency of production of short-range two-nucleon correlations in the lightest mirror nuclei containing three nucleons. The data were obtained for a certain kinematic range during electron scattering by nuclei. The collaboration found that in light nuclei, neutron-proton pairs are formed approximately twice… Continue reading Mirror light nuclei differed from heavy ones in the frequency of nucleon pair production

Engineers have learned to touch the touch screen without contact

Engineers from China and Germany have created the GhostTouch device, which allows contactless control of capacitive touch screens, taking advantage of their design features and susceptibility to electromagnetic interference. The device can accurately simulate taps and swipes in different directions on the screens of many popular smartphones without touching them. Despite the fact that the… Continue reading Engineers have learned to touch the touch screen without contact

Tea drinking linked to reduced risk of death from all causes

American researchers have found that drinking tea is associated with a decrease in mortality from all causes, and also found a relationship with a decrease in the likelihood of death from cardiovascular diseases, coronary heart disease and stroke. The results of a survey and medical examination of half a million Britons aged 40 to 69… Continue reading Tea drinking linked to reduced risk of death from all causes

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

Daily inhalation of laughing gas left the patient unable to walk

American doctors described in The New England Journal of Medicine rare medical case. A patient was admitted to the hospital with symptoms of severe vitamin B deficiency.12 – impaired sensitivity and coordination of movements, up to the inability to walk. It turned out that over the past two months he had been inhaling nitrous oxide… Continue reading Daily inhalation of laughing gas left the patient unable to walk
