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

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

Archaeologists have discovered a bronze figurine of Jupiter in Taman

Archaeologists explored the ancient settlement of Red October-1, located in Taman. As a result of this work, they established that the fortified settlement arose at the turn of the 6th–5th centuries BC and existed until the modern era. Among the rare artifacts discovered at this site were a gray clay lamp in the shape of… Continue reading Archaeologists have discovered a bronze figurine of Jupiter in Taman

Short breaks during the day helped workers cope with fatigue

Small breaks during the workday help you feel more alert, less tired and more productive. This was found by Romanian psychologists who conducted a meta-analysis of 22 studies published over the past 30 years. Article published in the magazine PLoS ONE. In modern culture, work and personal space no longer have clear boundaries, and more… Continue reading Short breaks during the day helped workers cope with fatigue

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

Electrical brain stimulation stopped overeating in two patients

Electrical stimulation of the brain has proven to be an effective treatment against overeating and obesity. This was discovered by American scientists who worked with two patients with compulsive overeating disorder. They activated the area of ​​the brain that is responsible for food cravings with an electric current – and as a result, the women… Continue reading Electrical brain stimulation stopped overeating in two patients

An antilaser with a degenerate cavity turned out to be an excellent absorber

Physicists combined the idea of ​​a coherent ideal absorber (antilaser) with the concept of a degenerate resonator. The constructed optical system effectively absorbs light incident on it from various angles, and its operation has proven to be resistant to typical interference in optical communication lines. The study was published in Science. Absorption is an important… Continue reading An antilaser with a degenerate cavity turned out to be an excellent absorber

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

Physicists made photons interfere with magnons

Chinese physicists have demonstrated quantum interference between waves of different natures, namely between photons and magnons. They repeated the Hong-Wu-Mandel experiment, where dark polaritons excited in an atomic cloud acted as a beam splitter. By controlling the properties of polaritons using an additional laser, scientists could change the nature of the interference from bosonic to… Continue reading Physicists made photons interfere with magnons
