TSU physicists are investigating the effects of radiation on DNA
Scientists from TSU's Laboratory of Experimental High Energy Physics and their colleagues from the University of Bordeaux are studying new ways of modeling the effects of low doses of radiation at the cellular level. For the first time, physicists will simulate the effects of radiation on DNA and calculate the probability of developing cancer in various chemical and biological environments.   This is an interdisciplinary project that combines modeling in physics, biology, and biochemistry. Scientists will investigate the processes occurring in the cell as a result of radiation exposure on environmental molecules and biological macromolecules and on subsequent physicochemical and biochemical processes.   When exposed to radiation on the human body, high-frequency radiation or high-energy particles penetrate into the living cell, knocking out electrons from the molecules that make it up. If at the same time ions appear in the cell or its DNA is damaged, then the cell cannot function normally. All these processes will be reproduced by mathematical modeling programs within the Geant4 software package.   - This integrated modeling tool is already used in nuclear medicine for treating oncological diseases and is also in demand in astronautics, for example, for preparing interplanetary expeditions, because it helps to predict the effect of radiation on astronauts and equipment during a long-term stay in space, explains Alexander Khodinov, Head of the Laboratory of Experimental High Energy Physics at TSU.   At the first stage, calculations will be made using the TSU computer facilities. The complexity of such work is that the calculation of each cycle or event takes up to an hour on a modern computer.   - The real representation of even a single cell requires the description of a number of components that is comparable to the description of a large physical installation, adds Alexander Khodinov. - We have to not only combine all the modeling processes in the same environment, but also increase the speed of calculations using hardware accelerators GPU and FPGA.   The new project became possible thanks to the participation of TSU physicists in the ATLAS and CMS experiments at the Large Hadron Collider (LHC) at the European Center for Nuclear Research (CERN). Approaches to creating computer programs for the LHC include developing methods for parallel computing and analyzing large amounts of data, which will now be used to study the effect of radiation on DNA.     Earlier, Tomsk scientists and their colleagues from France used the Geant4-DNA user application package for modeling electronic interactions in liquid water. The results are described in the article “Geant4-DNA Example Applications for Track Structure Simulations in Liquid Water: a Report from the Geant4-DNA Project”.

TSU research team will launch a start-up in the EU
A unique technology for cleaning bottom sediments of oil-contaminated bodies of water, Aeroschup, is about to enter the European market. It was developed by the Biological Institute (BI) of Tomsk State University. In April 2019, a BI research group took part in the Deep Tech Atelier conference in Riga (Latvia) and negotiated with the management team of Commercialization Reactor, an international technology commercialization platform. The product designed by the BI research team is now the basis of a start-up that will be established in the European Union for solving environmental issues there and in other regions of the world.   – Participation in the Deep Tech Atelier conference is the starting point for our collaboration with Commercialization Reactor, a platform that establishes new technological start-ups in Latvia, bringing together local entrepreneurs with scientists (mainly from Russia and the CIS), - says Danil Vorobiev, Director of the BI TSU. - Promising ideas for further markets are selected by a network of experts from big European companies. The Aeroschup project approved at the qualifying stage will be presented to experts and participants of the next commercialization reactor in Riga this autumn.     The technology for assessing and cleaning oil-contaminated bodies of water successfully passed pilot tests and was used in the northern regions of Russia. In 2018, the lake remediation project implemented in the Khanty-Mansiysk region together with Samotlorneftegaz JSC, a TSU industrial partner, was the winner in the Russian Geographical Society competition in the Best Environmental Project category. This technology is to become the basis for a company in the EU.   – During this business trip to Riga, we managed to establish a number of working contacts with entrepreneurs, including the director and founder of Commercialization Reactor, Nikolai Adamovich, who confirmed interest in the presence of TSU in the international start-up platform, – says Andrei Trifonov, Aeroschup project engineer.   Aeroschup is a potential participant in the next session to be held in October 2019. It is planned to establish a new separate start-up with TSU’s technology. This will encourage international investment in the product’s development and provide access to global markets. In addition, it will strengthen the position of TSU as one of the leading centers of innovation development in the Russian Federation.   Earlier, Ambassador of Portugal to Russia Paulo Vizeu Pinheiro and Attache for Scientific and Educational Relations João Carlos Mendonça expressed their great interest in the project. During the meeting with the director of the BI, they proposed to develop a joint Russian-Portuguese project based on TSU researchers’ ideas to design Aeroschup MARINE. It would solve the global problem of the need to clean bottom sediments in offshore shelf areas from hydrocarbon raw materials. The possibility of such collaboration with the Centre for Marine and Environmental Research (CIMA) at the University of Algarve, a leading center for marine research, is currently under discussion.   The Aeroschup technology was used to clean and restore the ecosystem of Lake Shchuchye (Komi Republic), which entered the Guinness Book of Records as a body of water that had been contaminated after one of the largest on-land oil spills on the planet. Scientists lifted 157 tons of oil from its bottom using Aeroschup technology.

What happens with the Arctic and subarctic lakes in the offseason?
Scientists at TSU, Umeå University (Sweden), and Midi-Pyrenees Observatory (France), under the SIWA (Siberian Inner Waters) international project, have studied for the first time the emission of greenhouse gases from thermokarst lakes in the cryolithozone of Western Siberia on a latitudinal gradient. The scientists have found that bodies of water formed as a result of melting permafrost emit a large number of greenhouse gases, and the maximum emission of carbon dioxide and methane is in the offseason. The research results of the international group are published in Nature Communications.   The interest in thermokarst lakes is very high, they have been actively investigated over the past few decades; however, previously Russian and international scientists worked locally, paying attention to only a few objects. As a rule, samples taken during one season were studied.   The first comprehensive studies of lakes in the Arctic zone of the Russian Federation were carried out by the TSU Bio-Geo-Clim Laboratory, headed by Oleg Pokrovsky, a scientist at TSU and the Midi-Pyrenees Observatory (Toulouse, France).   - Western Siberia has the world's largest frozen peat bog, which contains huge reserves of organic carbon,- says Ivan Kritskov of the Bio-Geo-Clim laboratory. - In the process of permafrost melting, carbon is released and partially migrates to adjacent bodies of water. However, a high concentration of dissolved carbon in the lake water does not guarantee the release of greenhouse gases into the atmosphere. In the course of research, we were able to determine the factors influencing the activeness of emissions, such as the depth of the lake, the air and water temperature, atmospheric pressure, air flow, and the intensity of greenhouse gas emissions into the atmosphere.   Sampling was carried out on 76 lakes in the Khanty-Mansi and Yamal-Nenets Autonomous Districts. Studies were conducted three times during the entire period of open water - in spring, summer, and autumn. The scientists measured the concentration of dissolved carbon in the lake water and studied the elemental composition and the volume of carbon dioxide and methane emissions from the water surface. As it turned out, the maximum emission of greenhouse gases occurs in spring, when lakes open up after winter and release reserves accumulated during the winter into the atmosphere, and in the autumn during the period of prolonged rains, when the water-covered area increases significantly.   - We tried to find out how strongly natural factors (size of lakes and watersheds, type of permafrost, and seasonality) affect greenhouse gas emissions,- says Artem Lim of the Bio-Geo-Clim Laboratory. – The results showed that latitude and seasonality have the greatest value on emissions, so emissions grow from south to north and reach their maximum in the zone of continuous permafrost, where they are 2–5 times more than in the south.   The comprehensive studies conducted by this international scientific group obtained a large array of unique data on the contribution of thermokarst lakes in Western Siberia to the greenhouse effect. This will enable a better understanding of the environmental transformation processes occurring in the Arctic zone of the Russian Federation and making much more accurate predictions about what will happen with permafrost and what climate changes humankind should expect in the future.   The authors of the article “High Carbon Emissions from Thermokarst Lakes of Western Siberia” are Svetlana Serikova (Umeå University, Sweden), Oleg Pokrovsky (TSU and Midi-Pyrenees Observatory), Rinat Manasypov (TSU), Ivan Kritskov (TSU), Artem Lim (TSU), Hjalmar Laudon (Uppsala, Sweden, Department of Forest Ecology and Management), and Jan Karlsson (University of Umeå, Sweden, Department of Ecology and Environmental Science).

Students from 8 countries discussed garbage reduction and eco-habits
The TSU Research Library held a student roundtable on the problem of rational attitudes toward consumption. International students told the audience what measures are used in their countries to reduce the amount of waste and which environmental practices help them make a personal contribution to preserving the purity of nature. This roundtable is one of the activities of EcoFest, which is taking place at the university from April 18 to May 8.   TSU students from the UK, Germany, Nigeria, India, Egypt, Pakistan, Mexico, and Brazil talked about how their governments solve the problem of garbage. Approaches are very different - from the complete prohibition of disposable packaging and legislative regulation of waste management to individual volunteer initiatives.   - We want to show that pollution of the planet with garbage is a global environmental problem that affects all nations and peoples. It was not by chance that we decided to open the EcoFest with an event in English with the involvement of international students, - says Asiya Boltovskaya, Faculty of Foreign Languages teacher and the organizer of the EcoFest. - We wanted to demonstrate that all countries have begun to realize the seriousness of the rubbish disaster and are trying to solve the problem of recycling and reducing waste. English as a language of international communication helped to unite representatives of different nationalities and made it possible to exchange views and experiences.     - I thought about my habits and about the effects they have on the environment, - says Edgar Solis Romeo, from Mexico, a student at Faculty of Innovative Technologies. - We need to understand that our lifestyle has a devastating effect on the planet. It struck me that glass decomposes for more than 1,000 years. We must act, even if it is not very convenient, to try to reduce the amount of waste we produce. For example, do not buy plastic bags.     - During the discussion, I learned that about 99% of purchased goods are thrown out by us after 6 months. I also often acquire new things before the old ones come into complete disrepair. Now I will reconsider my need for any novelties of the market, I will try to limit myself in consumption, - said the participant of the roundtable, Natalia Zakharchenko, a Faculty of Foreign Languages student. - I realized that the problem is worthy of our attention and we should reconsider our daily habits, which can lead to serious consequences and harm not only nature, but ourselves as well.   Artyom Dibrov, a student at the Faculty of Philosophy was very interested in the practice of separate garbage collection in different countries.    - For example, in England, a separate waste collection system is such that each house has 4 containers and centralized waste disposal is provided. That is, the practice of separate collection is supported at the state level, - said . - The story about the movement of the freegans and the zerowasters made me think about reducing the level of consumption. EcoFest Clean University, dedicated to International Earth Day, takes place at Tomsk State University from April 18 to May 8. The project includes a series of environmental education and educational events for TSU students and staff. The purpose of the eco-marathon is to promote an ecological culture at the university and to promote the separate collection of waste.

International students attended painting and sculpture classes
20 students from Vietnam, China, Brazil, Syria, Chile, and France have attended painting and sculpture classes at Children's Art School №1. Such classes help develop speech skills and expand vocabulary: international students learn specific terms and concepts in Russian and become more familiar with Russian culture.   - For me, this is the first experience of working with international students, and I must pay tribute to the University, that the students are well prepared and have a good command of Russian - said Olga Dvizova, director of Children's Art № 1. - These are guys who have no relation to the visual arts, but they were interested. We met with the directions of painting, materials, equipment, colors, and shades. In addition, they are well aware of realist artists, representatives of our national school – Repin and Shishkin. However, they did not quite understand the names of the impressionist artists of the French school, for example, Van Gogh, Gauguin, and Renoir. They have these names sound different, and in our pronunciation they are not completely recognizable.   The art classes were attended by students of different faculties - Faculty of Philology, Biological Institute, Faculty of Geology and Geography, Institute of Economics and Management, Faculty of Radiophysics, Faculty of Physical Education, and Faculty of Psychology. They painted watercolor with an apple from nature and also sculpted animals from clay. Then the figures will be baked, and the authors will receive them as a keepsake.   - It was very interesting. We learned new art terms, learned how to draw an apple. The lesson was unusual, it differs from our courses. When everything was done, I realized that I could still draw, - Mu Yuxi, a student from China, shared her impressions.   While studying at TSU, international students not only study their chosen specialty and improve their knowledge of the Russian language but also get acquainted with Tomsk and Russian culture. They teach Russian folk songs, types of painting and participate in the traditional festival of folk crafts Axe Festival.   - We strive to diversify the Russian language classes for international students so that they also become familiar with our culture,- said Anna Khiznichenko, Associate Professor at the Faculty of Philology.   In 2017, the Associate Professor Faculty of Philology Galina Starikova specifically for the development of speech among international students released the textbook “Let's Talk about Russian Painting: Russian Art in the Lessons of Russian as a Foreign Language”.

Well-known designers and art historians are working with TSU students
The Department of Design of the TSU Institute of Art and Culture has launched an interdisciplinary educational program Art & Science: Art. Design. Technology. Classes for undergraduates are conducted by both teachers of the Institute of Arts and Culture and the Siberian Design Center, and the best Russian and international experts in design and contemporary art.   Among them are Dmitry Bulatov, the Russian contemporary artist, art theorist, and curator; Antonio Geusa, the theorist of contemporary art and curator; Antonio Vilches-Nogerol, head of the ART-Design creative studio; and Aristarkh Chernyshev, Russian media artist.   - Art & Science is one of the modern interdisciplinary frontiers, where scientific knowledge and new technologies are conceptualized and used by artists, designers, and developers. The design is needed in scientific projects, and science is needed in modern design. Artists are working with scientific material, scientists are working with the creative possibilities of art. We have created a Master’s program for such complex interdisciplinary tasks (like other programs of the StrAU Institute of the Human of the Digital Era). The first semester of the program began in the fall of 2018. Currently we have places for a fee and 5 budget places, - says Professor Dmitry Galkin, head of the program.   Expert of the program Dmitry Bulatov, for example, is known, in particular, for implementing world-class research and exhibition projects in Russia and Europe. He has more than 20 international exhibitions. Bulatov is a member of the editorial boards of magazines on contemporary art DOC (K) S (France) and NOEMA (Italy). He is also a two-time winner of the national prize Innovation (Russia, 2008, 2013). In 2014, he was nominated for Golden Nike by Prix Ars Electronica Festival (Austria) in Visionary Pioneers of Media Art.   - I enjoy working with TSU colleagues. It's nice to see new programs and features appear. Here the personal contribution of Professor Dmitry Galkin, who is not only a world-class researcher but also the creator of new education, means a lot. I was pleasantly surprised, for example, by the gallery in the main building, which he created, - notes Dmitry Bulatov.   Dmitry Bulatov adds that Institute of Arts and Culture students are very active and offer serious projects:   - This is not the first course I read at TSU, and I always enjoy communicating with students. Now we are analyzing not only the foundations of Art & Science and technological art but also their projects and practical developments with undergraduates. I am glad about their critical thought and desire to think about current problems. I will wait for their first joint exhibition in May this year.   The program Art & Science: Art. Design. Technologies includes such areas as practical synthesis of arts, design and engineering for innovative enterprises, speculative / critical design, practices of modern art, digital design and prototyping, directing and storytelling, and FabLab workshop.
