MOSCOW, June 1. /TASS/. Stone axes from as far back as the Bronze Age have been discovered during the construction of Zaryadie Park in downtown Moscow, the capital’s city hall said in a statement on Thursday.

"Both axes are made of stone dating back to the turn of the 2nd and 3rd centuries BC," the city hall statement read, adding that the artifacts had been found in the 16th and 17th century soil layers.

"They could have been used as amulets," the statement said.

The axes belonged to an ancient tribe that lived in the European part of Russia during the Bronze Age.

MOSCOW, June 1. /TASS/. Russian scientists together with colleagues from the US and Israel have come closer to establishing a mathematical model of how water microdroplets organize themselves, the press service of Tyumen State University (TyumSU) said.

According to the scientists, the directed droplet clusters might serve as handy model unit for detailed studies of reactions in aerosol drops.

Moreover, by researching microdroplets, insight can be gained into the working principles of various pollutants in the Earth’s atmosphere and of different biological processes inside living cells.

The scientists’ work has been published in the online mega journal, Scientific Reports.

What are water microdroplets?
Suspended water microdroplets form fogs, clouds, and steam over a cup of hot tea. Normally, these droplets move in a chaotic way and do not form any organized structures, but in 2003, Russian scientists led by Tyumen State University research assistant Alexander Fedorets demonstrated that under certain conditions, microdroplets levitating over the surface of heated water can accumulate into so-called clusters - regular structures consisting of hexagons with separate droplets "hanging" in the apices.

The study’s results
"Previously, we had already undertaken a number of studies devoted to the droplet clusters," Fedorets told a TASS correspondent.

"We studied issues linked to the levitation of microdroplets, temperature fields defining such processes, and searched for ways to control these clusters. In our new study, for the first time we conducted a complex analysis of all basic physical processes accompanying the formation of stable droplet clusters and have laid the groundwork for a physical-mathematical model for such self-organization."

In that way, the scientists evaluated the Voronoi entropy, the value characterizing the degree of order for the system of microdroplets, and have shown that they become more organized as the cluster size increases

An innovative mouth rinse solution developed at the National University of Science and Technology MISIS (NUST MISIS) in cooperation with researchers from Vyatka State University was shown to have a substantial impact on oral cavity microflora, removing 83 percent of dental plaque.

Russian Researchers Develop New Blood and Biofluids Transportation Technology
The product’s effectiveness was proven during clinical trials at the Dentistry Department of Kirov State Medical University.


Dentists currently recommend mouthwash and oral irrigators (devices that use a stream of pulsating water to remove dental plaque) as the best supplements in oral hygiene, helping kill bacteria that cause plaque, and remove food debris between teeth that cannot be removed with a toothbrush or floss. Together with medical experts, NUST MISIS researchers developed an oral rinse that, if used regularly, suppresses pathogenic oral bacteria, reducing the risk of dental carries and gum diseases. The product’s effectiveness hinges on the use of metal nanoparticles. Experiments showed that these particles stop bacteria that cause plaque from growing.

“Pathogenic bacteria can be killed through chemical destruction of cell walls and various membranes, including cell organelle membranes, specifically when metal nanoparticles enter into contact with biopolymers of microbial cells. The cell membrane breaks down, releasing its content into the environment. With its bactericidal and bacteriostatic properties, the solution exceeds antibiotics by far when it comes to dealing with staphylococcus aureus and most coccus varieties,” the project’s co-author, Svetlana Gromova, said. Gromova is dean of the Dentistry Department at Kirov State Medical University.

New Antibacterial Bioactive Coating to Protect Implants Developed in Russia
During clinical trials at Kirov’s Dentistry Department, volunteers were asked to use the new mouthwash for one month, and measurements were taken after 14 and 30 days of using the product. It turned out that bacteria that cause plaque are sensitive to various solutions that contain metal oxide nanoparticles. Microorganisms were also less prone to adhering to teeth and causing inflammation. If used regularly, the product helped reduce oral fungal microbiome, normalizing salivary pH.


Head of the research team, Associate Professor at NUST MISIS Department of Physical Chemistry, Georgy Frolov commented on the scientific outcome of the experiments: “Colloidal solutions of metal oxides are not toxic to humans. They have a lasting anti-bacterial effect against dental plaque microorganisms, while also serving as a source of microelements. As we saw during research, using a metal oxide mouthwash substantially reduces soft dental deposits, reducing pathogenic microflora, all but eliminating it.”

NUST MISIS laboratories are currently making the first test batches of the product, patents and registration documents for medical use have been filled.

Russian researchers have developed a technology that makes transportation of blood and biofluid samples in medicine and veterinary science simpler and cheaper.
Materials specialists from the National University of Science and Technology MISIS (NUST MISIS) and their colleagues from the Chemistry Department of Lomonosov Moscow State University have developed a technology that makes it simpler, more reliable and cheaper to take biofluids samples, as well as to store and transport blood and biofluid samples in medicine and veterinary science.

Russian Researchers Test Unique Implants for Bone Defect Replacement
Two approaches are currently used for transporting blood and biofluids in medicine and veterinary science: transportation of liquid samples and the manufacture of dried preparations with the subsequent restoration of solutions. Vacuum blood collection tubes used to transport liquid samples require special transportation and storage conditions, namely, containers where samples are stored at low, and often subzero, temperatures. As a rule, delivery timeframes are tight. Blood samples change their properties if preset temperatures or deadlines are violated during delivery and storage, leading to inaccurate results in medical tests.


Another method involves the use of dried samples for medical tests. For this purpose, several drops of blood are placed on special cellulose cards and dried. This method is difficult to use because Russia does not make such cellulose cards. Moreover, not every clinic has the expensive specialized equipment required to test dried preparations.

“Due to the complicated structure of cellulose, blood is distributed unevenly on the carrier and becomes sorbed by the material, and this seriously distorts results,” Assistant Professor Alexander Osipov, Ph. D. (Chemistry), a senior research associate with NUST MISIS’ faculty of functional nanosystems, noted.

Russian scientists solved the problem by replacing the cellulose from which biofluids sampling cards are made with a specially prepared porous inorganic material containing nano-particles of metals.

Russian Researchers Contribute to the Creation of a New Family of Substances
The scientists have managed to come up with the right composition and form of absorbent, so that blood would be distributed evenly over the entire volume, and so that sorption levels would be minimized. In addition, blood components that are being tested would completely mix with the solution, while being washed off from the biofluids sampling card.


Modified samples dry about two times faster on the new material, and this considerably expedites the process of preparing samples. The new material’s advantage lies in the fact that there is no need to use special containers for transportation; an ordinary paper envelope would suffice. The delivery process is considerably simpler and cheaper, as compared to the use of containers and special-purpose vehicles.

NUST MISIS sources note that each hand-made card costs almost five times less than imported cellulose equivalents. In fact, one such card costs 40 rubles, rather than 180 rubles, even when produced in limited quantities. Their price will go down after large-scale production is launched.

The technology’s creators have patented it and have so far decided to focus on veterinary diagnostics. Experts working in this area have to conduct hundreds of thousands of tests all the time. As a rule, livestock farms, especially those in remote areas, lack the required conditions for doing this. Developers hope to mass-produce biofluids sampling cards by late 2017, after completing tests and certification procedures.

ST. PETERSBURG, June 3. /TASS/. Rollout of blockchain technologies and legalization of cryptocurrencies will help to tackle the problem of funding shortage for startups, Supervisory Board Member of Ethereum Fund Vladislav Martynov told TASS in an interview on the sidelines of the St. Petersburg International Economic Forum (SPIEF) on Saturday.

"I am confident legalization of ICO [Initial Coin Offer - initial offering of cryptocurrencies on a crypto-exchange - TASS] will help to solve one of the most challenging problems of Russian startups - investments shortage problem. From my point of view, it is much more efficient than direct state funding of the innovative economy development," Martynov said.

Legalization of virtual money will also improve financial security of Russia, he said. "We are depending on SWIFT now, on global payment institutions. Our dependence will be smaller when we will have "crypto-ruble" and an absolutely new global system of mutual settlements, with China thinking about developing its counterpart," Martynov added.
