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

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

Physicists saw Rabi oscillations using extreme ultraviolet light

European physicists have reported the observation of characteristic doublets in the spectra of electrons knocked out of helium atoms by coherent light in the extreme ultraviolet range. The result obtained indicates the occurrence of Rabi oscillations in atoms. The shape and position of the doublets could be theoretically reproduced only after taking into account the… Continue reading Physicists saw Rabi oscillations using extreme ultraviolet light

Pork protein corneas restored vision to 20 patients with keratoconus

Swedish scientists have developed corneal prostheses based on collagen from pig skin. In a pilot trial involving Indian and Iranian researchers, the prostheses helped restore vision to 20 patients with keratoconus. The report on the work was published in the journal Nature Biotechnology. The cornea is the anterior most convex part of the fibrous membrane… Continue reading Pork protein corneas restored vision to 20 patients with keratoconus

Physicists have found the secret to the perfect pass in American football

American physicists have built the most accurate mathematical model of ball flight for American football and rugby to date. They found that the Magnus effect and the effect of the Earth's rotation have little influence on the outcome of a spiral pass, in contrast to the initial angle between the axis of the ball and… Continue reading Physicists have found the secret to the perfect pass in American football

The most expensive drug in the world is a new therapy for beta thalassemia. One injection costs $2.8 million

The United States has approved gene therapy for beta thalassemia, an inherited blood disease. The developer of the drug, Bluebird bio, claims that one injection is enough to, if not cure, then significantly improve the patient’s condition. But such an injection would cost $2.8 million. This is 700 thousand dollars more expensive than the Zolgensma… Continue reading The most expensive drug in the world is a new therapy for beta thalassemia. One injection costs $2.8 million

Jupiter has limited the parameters of dark matter

Theoretical physicists have proposed a new method for constraining the parameters of dark matter based on data obtained by the orbiting Galileo spacecraft and the Juno station. The researchers calculated the flux of relativistic charged particles produced as a result of the annihilation of dark matter particles and compared the resulting theoretical value with the… Continue reading Jupiter has limited the parameters of dark matter

Solar power plant mirrors roasted chili peppers

An American engineer used light collected by the heliostats of an experimental solar power plant to roast green chilies and compared the result with the product obtained by traditional gas burner roasting. A blind tasting showed that the new method resulted in better flavor and more uniform processing of the peppers. The developed approach can… Continue reading Solar power plant mirrors roasted chili peppers

Fluorescent macaque clones helped evaluate the safety of targeted genome editing

Chinese researchers used the ABEmax base editing method to turn off a fluorescent protein in clones of a genetically modified rhesus monkey. Using their own approach, they analyzed the number of non-target mutations that arose and came to the conclusion that there are practically none of them in DNA, but there are many of them… Continue reading Fluorescent macaque clones helped evaluate the safety of targeted genome editing

Physicists have created a split neutron interferometer

European physicists have built the world's first separated neutron interferometer. In their experiment, they worked with a symmetrical circuit in which only the analyzer is movable. Thanks to a high-precision positioning system and temperature control, they were able to obtain a contrast interferogram. In the future, their developments will help create an skew-symmetric neutron interferometer,… Continue reading Physicists have created a split neutron interferometer
