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

Compression socks protected the intestines of marathon runners from damage

Australian sports doctors, with the participation of fifty runners, studied how compression socks affect the effects of running on the digestive system. After the marathon, those who ran in knee socks had lower levels of a protein marker of small intestinal damage. In an article published in The Journal of Strength and Conditioning Researchthe authors… Continue reading Compression socks protected the intestines of marathon runners from damage

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

Evolution forced mammals to recreate salivary proteins fifteen times

American bioinformaticians have discovered traces in the genomes of mammals of 15 independent occurrences of new proteins responsible for the viscosity of saliva. According to the findings of the authors of a study published in Science Advancesthe culprit is a region of the genome with a high mutation rate and selection pressure during the evolutionary… Continue reading Evolution forced mammals to recreate salivary proteins fifteen times

Watering with ethyl alcohol protected the rhizome from drought

Japanese geneticists have proposed increasing the drought resistance of plants using ethanol. They watered Tal's rhizomes (Arabidopsis thaliana) with a weak alcohol solution for three days and showed that this helped the plants survive the subsequent three-week drought. In response to alcohol, the plant activates the synthesis of the stress phytohormone, abscisic acid, which helps… Continue reading Watering with ethyl alcohol protected the rhizome from drought

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

Scientists introduced bacteria into artificial urine and obtained phosphate stones

Polish physicists and chemists modeled the formation of phosphate kidney stones using artificial urine and uropathogenic bacteria. Experiments in vitro in combination with computer modeling showed that the region of optimal pH values ​​(pH-optimum) for the formation of struvite, a component of phosphate stones, lies in the range of 8–9, shifting to the neutral side… Continue reading Scientists introduced bacteria into artificial urine and obtained phosphate stones

Denmark's trans fat ban prevented one in nine deaths from coronary heart disease

Danish and British researchers have found that since Denmark banned industrially produced trans fats in food in 2003, the number of deaths from coronary heart disease (CHD) in the country fell by about 11 percent. The results of the work were published in the journal PLoS ONE. Trans isomers of unsaturated fatty acids are present… Continue reading Denmark's trans fat ban prevented one in nine deaths from coronary heart disease

Butyrate saved mice from peanut allergies

Butyrate, which is produced by the intestinal bacteria Clostridium, may help people with severe peanut allergies. This was discovered by scientists who introduced polymer micelles with butyrate into the intestines of mice and relieved them of allergies. The authors believe that such micelles can also help with reactions to other food proteins. A preprint of… Continue reading Butyrate saved mice from peanut allergies

Oxytocin caused dogs to cry when reunited with their owner after separation

Japanese researchers have found that dogs cry when reunited with their owners after separation. This is due to an increase in oxytocin concentrations. The study was published in Current Biology. Dogs were domesticated and, through convergent evolution, learned to communicate with people through eye contact. For dogs, it plays a key role in the formation… Continue reading Oxytocin caused dogs to cry when reunited with their owner after separation
