An important disclaimer is at the bottom of this article.

The Moscow Architectural Institute (MARCHI) will receive a new academic building, which will become a striking architectural accent and provide students and teachers with modern conditions for education and creativity. This was announced by Deputy Prime Minister Marat Khusnullin.

"Modernization and creation of new modern premises for the country's leading educational institutions is a key element in the development of the capital as a global educational and scientific center. The implementation of such projects is aimed at improving the quality of education and creating comfortable conditions for students and teachers. As part of this work, the Moscow Committee for Architecture has approved a project for a new academic building with workshops for the Moscow Architectural Institute on Rozhdestvenka Street. The work will be carried out by the Single Customer in the Sphere of Construction PPC," noted Marat Khusnullin.

The complex will be located in the depths of the block at the address: ul. Rozhdestvenka, vl. 11. It will consist of two parts: a new five-story building, which will be built from scratch, and a one-story building (an unfinished project from 2008), which is awaiting reconstruction. Both objects will be connected at the basement and first floor level into a single whole with a common entrance group. The project solves a complex urban planning problem, integrating new volumes into dense historical development near the Kuznetsky Most metro station.

The five-story new building with workshops, classrooms and recreation areas features a dynamic and complex architectural solution. The building will also feature mirrored facades reflecting the sky and the city. The second building is a single-story building, and after reconstruction it will become a modern reminder of the historic carriage house that previously stood on this site.

The internal layout of the building is designed for a comfortable educational process: different floors will house sculpture workshops, classrooms for theoretical and practical classes in drawing and painting, as well as modern spaces for rest and work.

The design for the new academic building was developed by Moscow's chief architect Sergei Kuznetsov together with the art group "Stone".

"The MARCHI campus is an architectural chronicle, where each building stands for an era. Here is the estate of the architect Sergei Solovyov – an echo of classicism. Nearby is the Art Nouveau building of the architect Alexander Kuznetsov from 1911. Now it is our turn to add our chapter to the history of this place. It was important for us to come up with something unusual, because here they teach how to create architecture, the essence of which is magic. And students should absorb this from school. We decided to make a building that continues the avant-garde traditions of VKHUTEMAS – after all, this is where MARCHI has its roots. We wanted the architecture to be complex, bold, almost an engineering challenge: powerful consoles, hovering elements, a sense of a mechanism, and not the usual appearance of buildings. This is a structure that has dynamics, precision, and a bit of the Russian ideal – in the sense that it has a sense of scale and inner poetry,” said Sergei Kuznetsov, Chief Architect of Moscow and First Deputy Chairman of the Committee for Architecture and Urban Development (Moskomarkhitektura), which is part of the Complex of Urban Development Policy and Construction of the Capital.

The implementation of the project will not only expand the educational opportunities of the academy, but also create a children's art school on its basis, which will facilitate early professional orientation and training of future personnel for the architectural and construction industry of Russia.

"At present, a utility town has been set up on the site, and preparatory work for construction and reconstruction is underway. The total area of the two buildings will be about 3,000 square meters. They will have new workshops and at least 14 new classrooms. In total, up to 210 students and university staff will be able to study and work there every day. The reconstruction of the facility will create additional space for storing the methodological fund of large-sized exhibition materials. There will also be classes in art and design disciplines for both school-age children (from the 5th grade) and university students," said Karen Oganesyan, General Director of the Unified Customer in Construction PPC.

The project received the AGR certificate from the Moscow Committee for Architecture in August 2025.

The results of the FRP's activities were discussed in the context of the task of achieving technological and industrial sovereignty, including financing projects in the field of machine tool building, mechanical engineering, chemistry and pharmaceuticals, as well as the fund's contribution to solving unique innovative problems.

From the transcript:

M. Mishustin: Dear Roman Vasilyevich!

You are in charge of an important development institute – the Industrial Development Fund. A large number of projects have been supported by the fund, including in machine tool building, mechanical engineering, manufacturing, chemistry, pharmaceuticals, that is, in those areas where our country is actually addressing issues of supporting its sovereignty, as well as ensuring all the competencies that would make it possible to build up our own, domestic base in these important industries.

What results have you managed to achieve specifically this year?

Director of the Industrial Development Fund Roman Petrutsa at a meeting with Mikhail Mishustin.

R.Petrutsa: Dear Mikhail Vladimirovich, in August we exceeded the figure of 2,000 loans provided. Over 10 years, we have sent about 700 billion rubles to industry, and every third ruble has already returned to the Fund, and the funds that were at our disposal in 2015 have been directed to the third investment cycle.

The Fund's support is in high demand from the industry. And there is a steady positive trend in demand for our product. In 2025, we have about 100 billion rubles at our disposal, with most of it coming from previously financed projects.

Today, FRP is already a thousand launched production facilities, or modernized, mastering the production of new products. And every second of our projects has gone into production. And those projects that we have financed in recent years are already in the active phase of implementation. We are waiting for new launches from production facilities.

In 2025, we expect about 300 new projects. I reported to you earlier that our average pace in recent years has been 250-280 projects per year. This year, I am sure, we will cross the 300 mark. Of course, it is worth noting the quality of the Fund's portfolio. Today, it contains only 1% of problem assets.

It is also worth noting the socio-economic indicators. Our contribution to the country's economy is about half a trillion rubles of private investment. Our clients have already paid about 300 billion rubles in taxes to budgets at various levels. It can be said that 70 kopecks of every ruble financed by the Fund have already returned to the budgets. At the same time, I repeat, the Fund's capital has been preserved to date.

In 2025, as we all know, President Vladimir Vladimirovich Putin approved new priorities for the country's development until 2030, and in some areas until 2036. And 8 national projects of technological leadership fall within the scope of the Industrial Development Fund.

In the general line of development institutes of the VEB Group, our fund is a development institute that is responsible for the technological agenda, for industry. And by today we have accumulated a huge stock of competencies, knowledge and experience in financing technological projects. Thus, more than 40% of our portfolio is mechanical engineering, primarily transport. You remember, we actively financed auto components. And the second and third places are occupied by such knowledge-intensive industries as chemistry and pharmaceuticals.

In August 2025, a meeting of the visiting supervisory board of the Industrial Development Fund was held in Chelyabinsk, where decisions were made to prioritize the Fund's resources for projects that provide for the release of products included in the technological sovereignty maps. In our flagship basic program "Development Projects", this has become a priority.

M. Mishustin: Of course, we must continue to look for effective solutions in the field of industry and the economy. And it is very important that they are innovative. The fund helps, as you said, to attract private investment in industry, and the good, effective work of the fund shows how correctly the production was laid out, how well the financial model was implemented. And of course, private finance follows this. This is very important. And they go into well-thought-out innovative solutions.

My question will be the following: to what extent do you contribute to solving unique innovative problems? After all, considerable funds are allocated for research and development work, which is currently being carried out in the country, and the Ministry of Industry and Trade supplies special tools to those who invest in R&D. The fund, as you said, has accumulated competencies. What is happening with this?

R. Petrutsa: The Industrial Development Fund finances projects of various scales. We have both the purchase of several machines and the financing of large plants from scratch, requiring serious capital-intensive investments. And here we solve two problems: we strengthen medium and small businesses that localize the component base, and we give the opportunity to develop high-tech large-scale projects. At the same time, our entrepreneurs and industrialists not only create industrial sites, equip them with equipment, but also make a significant contribution to the intellectual potential of the country.

Over the years of the fund's work, our clients have filed more than 800 applications for registration of intellectual activity. Two thirds of the registered applications are new patents, inventions and utility models. And the majority are mechanical engineering, as well as pharmaceutical and other high-tech industries.

If we give examples, of course, there are a lot of them. Currently, the fund's portfolio contains more than a thousand projects. I know that in the summer you met the OrenKlip group of companies. They built a plant in an open field – the Orenburg Plant of Automation and Robotics, which will produce robotic equipment for the food industry.

This year, a project was launched in the Nizhny Novgorod region by the company "RusSilika". This is chemistry: components for 23 industries – in fact, for all. The project was included in the list of priorities by the Ministry of Industry and Trade. And the total budget of the project was 21 billion rubles, of which 5 billion were provided by the Industrial Development Fund.

In the Sverdlovsk region, the Cyberstal company launched a project to produce seamless stainless steel pipes. Until today, we imported these products. They are in high demand, especially in the nuclear power industry. The project budget was 12 billion rubles, of which 5.2 billion rubles were again the FRP.

The well-known Ural plant. The fund has already financed a number of projects of this plant. And now the legendary Ural truck will be equipped with its own bridges, front axle. At the same time, the products of the project will be supplied to other automakers for other trucks. That is, localization and cooperation among our auto giants is still growing. Together with the plant management, we participated in laying the first stone in the foundation of the foundry of the new building.

The Industrial Development Fund not only provides preferential loan financing. We are an expert organization within the framework of another key instrument – the cluster investment platform, where enterprises can also receive funds for large-scale projects in the format of preferential financing – from 2 billion to 100 billion rubles. Here, in symbiosis with the Ministry of Industry and Trade, the Industrial Development Fund and the banking system, more than 60 projects in this area have already been approved for a budget amount of more than 1 trillion.

M. Mishustin: Thank you, Roman Vasilyevich. The fund has many tasks for the coming years. First of all, these are the tasks of technological and industrial sovereignty that the head of state sets before us. They must certainly be solved.

To achieve this, of course, we need to increase efforts in all areas so that our economy develops dynamically, so that our competencies, research and development become the basis of a modern, powerful domestic industry. And this is the creation of new jobs, new competencies and, of course, the training of qualified, high-quality personnel.

On the night of September 7-8, a total lunar eclipse could be observed across almost the entire territory of Russia

Translation. Region: Russian Federal

An important disclaimer is at the bottom of this article.

On the night of September 7-8, residents of almost the entire territory of Russia could observe a total lunar eclipse. In Novosibirsk, there were ideal weather conditions that night – a clear and bright sky, so astronomy lovers could enjoy a rather rare astronomical phenomenon.

According to Egor Konyaev, an engineer at the Vega Observatory at NSU, the next total lunar eclipse, visible over most of Russia, will occur in 3 years, on December 31, 2028.

— According to local time in Novosibirsk, its maximum will be almost midnight (23:50). Therefore, it can already be called New Year's, — adds Yegor.

What is a lunar eclipse?

A lunar eclipse occurs when the Moon, in its orbit around the Earth, enters the shadow of our planet, and the Earth at that moment is exactly between the Sun and its natural satellite.

Why is the moon red? And why is it visible?

— The most important and interesting question that arises in the observer is: why does the Moon turn red during a total eclipse? And why is it visible if an eclipse occurs? It would seem that if the Moon is immersed in the Earth's shadow, it should not be visible at all. But this is not so. And here the Earth's atmosphere plays the main role, — explains Yegor Konyaev.

According to Rayleigh's theory, there is a dependence of the intensity of light scattering on the wavelength. Blue rays, which have a shorter wavelength, are scattered in the Earth's atmosphere 4-5 times stronger than red ones, which is why the color of the daytime, clear sky is blue.

— It is for this same reason that during a lunar eclipse the Moon takes on a red hue. Some of the rays that are refracted and not scattered in the Earth's atmosphere hit the lunar surface, from which they are reflected and "return" to the observer located on the Earth's night side. And we can observe such an interesting, beautiful effect when the Moon is painted in different shades of red — from copper-yellow to dark-dark red, — says Yegor Konyaev.

How often do lunar eclipses occur?

On average, both lunar and solar eclipses occur twice a year. But an observer on Earth has a much greater chance of seeing a lunar eclipse than a solar one. Why? The reason is geometry.

— A lunar eclipse looks the same wherever the Moon is above the horizon — its area is equal to a hemisphere. In addition, the Earth is larger than the Moon, so the Earth's shadow completely covers the Moon. During a solar eclipse, when the Moon moves in front of the Sun, the shadow cast by the Moon is much smaller than the Earth's and covers an insignificant part of the Earth's surface. Therefore, the chance to see a solar eclipse is only available to people located within a narrow strip of the Earth's surface along which the Moon's shadow passes, — adds Yegor Konyaev.

So, the next total solar eclipse, which will occur on August 12, 2026, in Russia can be seen only on the Taimyr Peninsula, but observation will be extremely difficult, since it is very low above the horizon and not all phases will be visible.

A total lunar eclipse has three phases. The first phase is the penumbral phase, when the Moon is still fully illuminated by direct sunlight, but falls into the Earth's penumbra. As it continues to move along its orbit, the Moon falls into the Earth's shadow, which completely blocks sunlight for some areas of the Moon – this is the shadow phase of the eclipse. When the Moon is completely immersed in the Earth's shadow, the total phase of the lunar eclipse occurs. This is the moment when the Earth's natural satellite turns red.

This time, the maximum phase of the eclipse was 136%, it was reached at 1:12 Novosibirsk time. The total phase lasted from 0:31 to 1:52, the umbral phase from 23:27 to 2:56, and the penumbral phase from 22:28 to 3:55.

What is interesting about a lunar eclipse?

As Alfiya Nesterenko, head of the Vega observatory at NSU, notes, this lunar eclipse was quite long, unlike those observed earlier. Thus, the phase of the total lunar eclipse this time lasted more than an hour.

“Also, during a lunar eclipse, you can discern relief details that are not noticeable on the Moon during normal times, due to the greater contrast of some elements,” adds Alfiya Nesterenko.

Four NSU students received an offer for an internship at Russia's largest IT holding following an educational intensive course

An important disclaimer is at the bottom of this article.

The final of the educational intensive course has ended in Novosibirsk, during which 18 students from Siberia received offers for internships at the country's largest IT holding company, T1, with four NSU students among the winners. The competitive selection for the internship was held among more than 7,000 applications from all over Russia. The final defense of the projects, which the students had been working on for two months, took place on August 28 at the Novosibirsk State University, with 38 students from different parts of Siberia participating.

As part of the intensive course, participants developed and presented their own solutions for real business cases, including the creation of a tool for booking meeting rooms and a service for verifying digital signatures.

In Novosibirsk, following the final defense of cases from real business customers of T1, the first place was taken by a team of six students, including Natalia Bedareva from NSU. While working on the projects, Natalia's team developed the corporate discussion service "MUZA". With its help, employees of the client company will be able to quickly resolve work issues, save the best cases, and also get access to a verified knowledge base, which will reduce the time it takes to find information. The holding will use the ideas and solutions of the camp participants in the further implementation of its own IT projects. Three more students from Novosibirsk State University became winners of the IT camp: Andrey Dutkin (2nd place), Dmitry Lutsev (2nd place) and Alina Brysina (3rd place).

IT holding T1 has been holding a summer educational bootcamp for the second year in a row, so that students from all over the country could try themselves in large projects, gain practical experience and take their first steps in their careers. This year, interest in the camp has grown significantly: the organizers received more than 7,000 applications – two and a half times more than in 2024. Almost 3,000 people passed the entrance test, and the best of them – over 1,500 students from 459 universities in the country – were enrolled in the intensive course. 73% of them are students of technical specialties from regional universities. The T1 IT camp was held in a hybrid format: the first remote stage was replaced by in-person team work on projects. The final defenses, in addition to Novosibirsk, also took place in Yekaterinburg and Moscow.

— The practice of the T1 IT camp once again confirms that regional training centers are becoming no less important than the capital. Novosibirsk is one of the main scientific and educational hubs of the country, and here we see very motivated and talented students ready for serious challenges in the IT sphere. I am glad that many of those whom I was lucky enough to meet during the defense of the final projects joined the T1 team in order to implement large-scale projects with us in the future, — noted Mikhail Knigin, Executive Director of T1 Integration (part of the T1 IT holding).

At the beginning of the training, the participants were given the opportunity to choose a specialization of training. The most popular was system analytics – every fourth student from Novosibirsk chose it. No less in demand were backend and frontend development, as well as manual testing and application administration.

Alina Brysina said that the process of working on the project became a real challenge for her.

— We received a very complex and detailed technical task, which turned out to be practically impossible to implement in such a short time frame with the number of people we had on the team. It was very difficult to understand which solution to choose. We had several types of administrators for the technical task in the project, and we decided to leave one, but because we did not record this requirement, the decision was ultimately difficult. It was as if everyone was speaking different languages, — shared Alina.

Alina was a systems analyst on the team and learned to be much more punctual, attentive to details and ask precise questions.

"I learned a lot from my colleagues and realized that large IT companies need reporting that is actually used. All the documents that a system analyst prepares are not just put into a drawer," she added.

Alina also emphasized that the team’s support helped her not to give up and continue working on the project, which allowed her to show excellent results and achieve victory.

SPbPU scientists have created the first analytical platform in Russia for designing optical systems

Translation. Region: Russian Federal

Source: Peter the Great St. Petersburg Polytechnic University –

An important disclaimer is at the bottom of this article.

Scientists from Peter the Great St. Petersburg Polytechnic University have created a unified database of chalcogenide glasses, which contains more than 20,000 records of their compositions and properties. The database is based on information published in scientific studies over the past 50 years, and includes most of the existing experimental results of studying the characteristics of chalcogenide glassy materials. Database chalcogenide glasses is patented and registered by the Federal Service for Intellectual Property (Rospatent). To work with the database, the Polytechnics developed a web interface that allows sorting, exporting and analyzing data by composition and properties. Thanks to this, new opportunities are opening up for the accelerated design of promising chalcogenide glasses – key materials for modern infrared optics, thermal imagers and night vision systems.

Chalcogenide glasses are amorphous inorganic materials in which oxygen atoms are replaced by sulfur, selenium or tellurium atoms. Chalcogenide glasses have attracted attention since their discovery due to their unique properties: due to the absence of oxygen in the structure, they have wide transparency in the infrared range, a high refractive index and a low softening point. The growth of practical interest in these materials in the last five years is associated with the development of thermal imaging systems and a more than threefold increase in the price of single-crystal germanium, the main material for the infrared spectral region up to 14 μm. Due to the great fragmentation and lack of systematization of published data, as well as the lack of a system for displaying the characteristics of glass compositions, the process of developing new compositions with the required set of properties has become more complex. Traditionally, it is based on the analysis of phase diagrams and the construction of local regression models.

To solve this problem, an interdisciplinary group of scientists from the Scientific and Educational Center "Nanotechnology and Coatings" of the Institute of Mechanical Engineering, Materials and Transport and the Higher School of Software Engineering of SPbPU carried out large-scale work to create a unified database. Using large language models (LLM – Large Language Model), scientists aggregated and structured information from more than 1000 scientific publications. In addition to the database itself, using artificial intelligence methods, models were developed to predict the properties of previously unknown glass compositions.

The main result of the work was not just a database, but an entire analytical platform. For the convenience of researchers, a specialized web interface has been developed that allows for prompt data analysis, comparison of results, and export of search results. To simulate the characteristics of glass before the stage of expensive laboratory synthesis, a model for predicting key glass parameters (density, softening temperature, refractive index) was developed based on machine learning models and neural networks. The proposed approach significantly reduces the time spent on developing promising compositions at the initial stage of research. In the future, it is planned to expand the scope of application of the predicted glass parameters, – said the project manager, PhD in Physics and Mathematics Victor Klinkov.

The software package can serve as a basis for the emergence of a new approach to the design of optical systems. The platform lays the foundation for a fundamentally different methodology: now it is possible to design "from the opposite" – from the characteristics required by the system to the targeted synthesis of material with the necessary parameter values. An important aspect of the project is its general availability. The platform creates a single field for scientific work, allowing both novice scientists and experienced specialists to quickly analyze their results in the context of global research practice and plan new projects.

The practical significance of the work lies in expanding the boundaries of understanding the nature of the glassy state using AI tools and in creating prerequisites for implementing these results in industrial optics design systems.
