Russian scientists have discovered a new physical paradox

Scientists from St. Petersburg Polytechnic University Peter the Great (Spbpu) found and theoretically explained a new physical effect, the essence of which consists in the possibility of growth of the amplitude of mechanical vibrations of an object without any external influence. In addition, they suggested that if the paradox of Fermi-Pasta-Ulam-Tsingou.

In SPbSPU is explained by a simple example: to rock the swing, they need to constantly push. It was believed that without continual external influence to achieve vibrational resonance is impossible.

A unique method of creating a powder composites developed in Russia

A new method of making composite metal powder has been developed by scientists of the South Ural state University (SUSU). The authors argue that their method allows to reduce production waste and improve the quality of electrical products and, as a consequence, to increase production efficiency by 30%. The study is published in journal Metallurgist.

A team of scientists of the University presented a unique method and design of the mixer to prepare a powder of composite materials based on graphite, coke and the polymeric component. The new method will improve the quality of the finished raw materials for the subsequent pressing process and to reduce waste production in nuclear energy, aviation and space industry, metallurgy and electric transport.

Scientists have identified the influence of wage growth in the regions of migration to the North

Scientists from Tyumen and Kazan found that wage growth in the European regions of Russia significantly affects migration in the far North, told RIA Novosti at the Tyumen state University (TSU).

According to the researchers, one of the reasons for negative migration growth of the population in the far North may be closing the gap in wages between the North and other areas of the country, including the regions of Central and southern Russia, where the salary for the last 15 years have grown faster.

In Russia have found a way to safely recycling oil

Economical and environmentally friendly method of disposal of waste from drilling wells has been developed by scientists of the Tyumen industrial University (TIU). According to the authors, their development will help considerably to reduce the toxic environmental impact of oil production on land. About it reported in a press-service of the University.

When drilling oil wells, as explained by the experts, they injected a special saline solutions, water-or oil-based. Out of the hole, breed with such additives are toxic for the environment, and the elimination of contamination is more than ten years.

Russian scientists have proposed a way to detect kidney cancer at an early stage

Professor-researcher at the Institute of living systems of the Baltic Federal University named Kant (Kaliningrad) Liudmila Matskova, together with colleagues from China have proposed a method of detecting kidney cancer at an early stage on the basis of molecular biology techniques that will improve the effectiveness of treatment of this disease, reported the press service of the BFU.

Kidney cancer in most cases are asymptomatic, and clinical manifestations occur mainly in the later stages, when the treatment is ineffective. The average life expectancy of these patients is limited to a period of five years. It is therefore important to find ways to "detect" the beginning of tumor growth as early as possible. Now scientists have found that in cells of kidney cancer compared to their healthy "brothers" are decidedly less protein 4 cadherin – molecules, whose function is to "consolidate" normal cells together.

Scientists have learned how nanoparticles kill cancer cells

Effect of magnetic nanoparticles on cancer cells human liver studied by the researchers of Baltic Federal University (BFU) to them. Kant and nust "MISIS". According to the authors, their study may improve the treatment of cancer. The results published in the journal "Nano Сonvergence".

Thanks to its unique properties, magnetic nanoparticles can be used in theranostics diagnosis and personalized treatment of oncological diseases, and also be an effective contrast agent for MRI in the examination and visualization of tumors.

Scientists have found a way to improve the drug of complications from COVID-19

Employees of the Samara national research University named after Sergey Korolev found that the pulsed magnetic field increases the effect of a drug pentoxifylline, which a number of scholars regarded as medications to prevent dangerous complications coronavirus infection, reported the press service of the University.

One of the extremely dangerous complications coronavirus infection is thrombosis (blockage by blood clots) of pulmonary artery. Pentoxifylline reduces blood viscosity, prevent aggregation ("bonding") of blood cells - trombotsitov and blood clots and increases the concentration of oxygen in the tissues.

Scientists figured out how to reduce the cost of monitoring road 400 times

The satellite observations that will improve the design and maintenance of road infrastructure, created by scientists of the Tyumen industrial University (TIU). According to them, the system not only processes data faster and more accurately than their counterparts, but also more economical to operate more than 400 times. The results were published in the journal IOP Conference Series Materials Science and Engineering.

During operation, the design and reconstruction of various road projects — streets and highways, intersections, bridges and interchanges — regularly have problems, the solution of which, as explained, scientists TIU, requires collecting and analyzing huge amount of data on the road network.

Plague in the era of the stone age: the sick and how he treated the old man

Cholera, Spanish flu, smallpox, the plague – humanity is not the first time confronted with large-scale epidemic. Many write in the history books, but what if you look a little further? Do you know something about the epidemics of the stone age? As the ancient people cope with the disease? These and other issues, RIA Novosti said the anthropologist, doctor of historical Sciences, academician of RAS, Director of Scientific research Institute and Museum of anthropology Moscow state University. M. V. Lomonosov (MSU) Alexander bojilova.

Today, according to experts, actively conducts research to understand what infections have been infected by people of the stone age. Thanks paleogenetics, new data on the existence of plague in some ancient Eurasian societies in the period of transition from the stone age to the bronze age.

Scientists have modeled the chemistry of the human brain exposed to violence

Scientists of the South Ural state University (SUSU) has created the world's first experimental model of severe mental state of a person – complex PTSD (C-PTSD). The development will help to create and test medications for the treatment of the disease. Results published in the scientific journal psychoneuroendocrinology is.

According to experts, post-traumatic stress disorder (PTSD) is a severe mental condition arising from events that had a powerful negative impact on the psyche. This can be the situation is life threatening, receiving serious injury or sexual violence.
