Poor protein utilization contributes to neurodegeneration

Neurodegeneration can occur more quickly if nerve cells lack retromer proteins, which are responsible for breaking down toxic tau protein. This conclusion was reached by scientists who observed genetically modified fruit flies that produced human tau protein in 39 neurons of the eye. Tau protein itself already caused the death of nerve cells, and the… Continue reading Poor protein utilization contributes to neurodegeneration

Chemists have found ideal conditions for the hydrogen borrowing reaction

Chemists from Russia studied the hydrogen borrowing reaction necessary for the formation of carbon-nitrogen bonds. They found that it often does not require a catalyst at all, and also developed recommendations for successfully carrying out the reaction in the laboratory. The study was published in the journal Journal of Catalysis. Organic compounds containing an NH… Continue reading Chemists have found ideal conditions for the hydrogen borrowing reaction

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

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

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

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

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

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

Psilocybin and psychotherapy reduced cravings for alcohol

A double-blind, randomized clinical trial conducted in the United States found that psychotherapy with two doses of high-dose psilocybin significantly reduced drinking in alcohol-dependent patients for at least 32 weeks. The work report was published in JAMA Psychiatry. The potential benefits of psychedelics for the psychotherapy of alcohol dependence syndrome were indicated half a century… Continue reading Psilocybin and psychotherapy reduced cravings for alcohol
