The research team of the Department of Organic Chemistry of Samara Polytech under the leadership of Doctor of Chemical Sciences, Head of the Department Yuri Klimochkin and Doctor of Chemical Sciences, Professor Alexander Reznikov in cooperation with the crystallographic research group of Lomonosov Moscow State University (supervisor - candidate of chemical sciences, senior researcher Victor Rybakov) completed a study to obtain non-racemic 4,5-dihydrofurans based on Michael addition and study their chemical properties. The announcement of a scientific article with the results of the latest research is posted on the cover of the authoritative journal Studying the method of obtaining non-racemic 4,5-dihydrofurans will make it possible to create biologically active compounds, and it is also possible that some of them are potential drugs against cancer, neurodegenerative diseases, Dmitry Nikerov, assistant of the Department of Organic Chemistry says.

A research group from Aarhus University has developed a special biocompatible electrode for electrical muscle stimulation that the group has integrated and 3D-printed onto medical support stockings.
In the winter 2020/2021, the stockings were tested on hospitalised Covid patients. The studies were completed in March, but apart from a case study (
Danish Medical Journal) data have not yet been published. However, the project group reveal that the results are very promising.
The stockings were tested on 16 Covid-19 patients who agreed to try the support stocking during their hospitalisation. The participants were hospitalised for five to seven days and were given a support stocking on each leg, but only one of them had the printed electrodes. The leg without electrodes on the support stocking functioned as a control.

Dark Matter Particle Explorer (DAMPE) Collaboration directly observed a spectral softening of helium nuclei at about 34TeV for the first time. This work was based on measurements data of the helium spectrum with kinetic energies from 70 GeV to 80 TeV (17.5 GeV/n to 20 TeV/n for per nucleon) recorded by the DAMPE.
The relevant results were published in
Physical Review Letters.
Galactic cosmic rays (GCRs) offers important ways to deeply understand the astrophysical particle origin and accelerators and the interstellar medium of the Galaxy. Helium nuclei, the second most abundant nuclear element of cosmic rays, is a distinguishing feature of space.

Singapore University of Technology and Design (SUTD) researchers have uncovered how the environment can impact highly sensitive quantum behaviours like localisation. Their findings, published in
Chaos, could lead to future innovations in the design of superconducting materials and quantum devices, including super precise sensors.
Quantum technology, in particular quantum sensing, promises to measure and capture our world at levels of precision never before possible. Such precision has diverse applications, from speedier and more sensitive medical imaging to recording time on high-frequency market trades, and even the development of sensors that can determine whether the ground beneath us is solid rock or a natural oil-and-gas reservoir.
A breakthrough study by Bryan Shaw, Ph.D., professor of chemistry and biochemistry at Baylor University, aims to make science more accessible to people who are blind or visually impaired through small, candy-like models.
