Zanton MS, a resident of the Technopolis Moscow special economic zone (SEZ), has begun producing high-tech CT and angiography systems for the comprehensive diagnosis of tumors and cardiovascular diseases. This was announced by the Deputy Mayor of Moscow for Transport and Industry. Maxim Liksutov.

"At Sergei Sobyanin's direction, we are paying special attention to the development of the medical industry. Thanks to the city's support, one of the residents of the Technopolis Moscow SEZ has launched production of high-tech CT and angiography systems. The company plans to produce 60 such devices annually," said Maxim Liksutov.

An angiograph examines blood vessels using X-rays and contrast media. The resulting data allows doctors to accurately diagnose various conditions, such as arterial stenosis. CT scanners detect tumors in the brain, breast, pancreas, colon, lungs, and other organs.

Product improvements are possible thanks to the support of the Moscow Government. Resident companies of the Technopolis Moscow SEZ can enjoy extensive tax incentives and benefits: for 10 years, businesses are exempt from property, land, and transport taxes, and the profit tax rate is reduced to two percent instead of 25 percent. Residents also do not have to pay customs duties or VAT when importing goods and equipment under the free customs zone procedure. Companies use the savings to increase production volumes and develop and implement new high-tech solutions.

A mythical alicorn and a robot tour guide. The history and present of the Biological Museum

Translation. Region: Russian Federation –

An important disclaimer is at the bottom of this article.

K.A. Timiryazev State Biological Museum— a visual encyclopedia of the evolution of the living world, accessible to schoolchildren and useful to students, scientists, and professionals from various fields. It also features a new, modern space, "Biocluster." Moscow Culture's guide to this world is Elena Mikheecheva, a first-category methodologist. Her story is a journey through the museum's history and exhibitions.

Two halls and a corridor

"The State Biological Museum opened in 1922—and not here, but in a building on Miusskaya Square," says Elena Mikheecheva. "Now the Russian State Humanitarian University is located there, but at that time it was the Ya.M. Sverdlov Communist University, where the museum's founder and first director, Boris Zavadovsky, was head of the biology department. At the very beginning, the museum had only two halls and a corridor." In the late 1920s, the museum was forced to leave its building on Miusskaya Square and separate from the university; this was a difficult period. But in 1934, the museum moved to the former estate of merchant Pyotr Shchukin, which it still occupies today.

Boris Zavadovsky was a physiologist, and this left its mark on the collection. Elena Mikheecheva points out the exhibits in the first halls, which might confuse or even frighten the unprepared visitor—the display cases showcase medical and physiological experiments. "Boris Zavadovsky researched the endocrine system. These halls are dedicated to human and animal physiology: the nervous and circulatory systems, digestion. The direct connection between experimentation and medicine is one of the key ideas of the museum. This research was aimed at healing people. Not everyone likes it, but I assure you, children take it completely calmly. The museum's conventionality suits them perfectly," the guide notes.

Elena Mikheecheva suggests looking at this from a scientific and humanistic perspective: “You can approach the display cases with exhibits and say thank you, because without the participation of these dogs and other experimental animals, we would never have learned to treat many diseases or perform successful transplant operations.”

From truffles to witch circles

The museum's halls present biology in incredible diversity. "We display all kingdoms of the living world," explains Elena Mikheecheva. The kingdom of fungi occupies two halls, and this collection is a three-dimensional encyclopedia. "We have the opportunity to see things we don't usually see: the underground bodies of mushrooms, truffles—the most prized mushrooms," says the methodologist.

The exhibit also serves an educational purpose, highlighting its treacherous lookalikes. "For example, the death cap is a deadly poisonous mushroom. We present several variants, and show you what other mushrooms it might be confused with," the guide explains.

Here you can explore the mysterious phenomenon of a fairy circle, where mushrooms form a perfect ring. Elena Mikheecheva smiles as she recounts ancient superstitions: "It's not a dance of spirits or witches, as was once thought. The mycelium is round because it grows outward from the center, dies in the center, and young mushroom fruiting bodies appear along the outer ring. And there's no magic involved."

Flight of the Snow Leopard

The hall, which emphasizes the interaction between nature and man, is called "Nature and Man." Its dominant feature is a majestic snow leopard, frozen mid-spring. "This is a mountainous area, a cliff, where we see an endangered species—a stuffed snow leopard. All visitors are particularly interested in how it's frozen mid-spring. The complete illusion of movement, the mountings are invisible from any angle—this is the pinnacle of taxidermy art. The artist is Vadim Khrenov," explains Elena Mikheecheva.

A hall dedicated to ecology also reminds visitors of the fragility of life. "This is a stretch of coastline on the Commander Islands, and here we see parts of the skeleton of the famous Steller's sea cow. The animal disappeared in the 18th century," the guide continues.

Nearby is an urban artifact. "It's a crow's nest, made using polyethylene rope and wire. This shows that animals can, after all, adapt to life in urban environments," comments Elena Mikheecheva.

From giant mollusks to humans

Elena Mikheecheva proudly leads the way to the next hall. "Our most beautiful hall is called 'The Development of Life on Earth.' It presents vanished paleolandscapes—from ancient times to the present. The hall consists of two levels. The upper level contains models of paleolandscapes: the Silurian, Devonian, and Jurassic periods. The lower level displays authentic objects characteristic of each period," she explains.

Among them are fossilized mollusks, skeletal fragments, and imprints of ancient plants. Visitors immediately notice the models of giant reptiles and tree ferns. Among these giants of the past, the ancestors of all mammals are present, discreetly, almost unnoticed. "I want to draw attention to these little animals. They are the ones who defeated the giants in the struggle for existence," says Elena Mikheecheva.

The exhibition "How to Get Along with the People," housed in a separate hall, offers a contemporary perspective on anthropogenesis. The museum's particular pride is the plastic reconstructions of ancient people's faces, created using the method of anthropologist Mikhail Gerasimov. "Mikhail Mikhailovich worked at our museum for some time. His method is still relevant today—both in science and forensics. It has given rise to computer programs that help reconstruct the faces of people who lived in ancient times from skull fragments," the guide emphasizes.

Cave paintings and 3D of the last century

The vaulted ceiling of the "Origin and Development of Man" hall is enhanced by images replicating ancient cave paintings. Artistic motifs from various caves around the globe are used here.

The "Fundamentals of Evolutionary Theory" hall is also of interest to members of the professional community. "It primarily displays exhibits from the 1950s. Museum workers who visit us say this hall doesn't need updating because it's a monument to museum art," shares Elena Mikheecheva. At the same time, the hall remains relevant and continues to amaze modern visitors. The dioramas by People's Artist of Russia Yefim Deshalyt are the pinnacle of diorama art. Elena Mikheecheva explains: "We look at the diorama 'Sandy Desert' and see no boundary between the painting and the foreground, three-dimensional object. Children even say, 'This is 3D from the last century.'"

Alicorn guards the museum

The tour concludes with a history of the museum's building complex. It is a federal cultural heritage site, an architectural masterpiece built in the pseudo-Russian style fashionable in the late 19th and early 20th centuries: hipped roofs, red brick, ornate columns, and glazed tiles. The buildings resemble the towers of Russian fairy tales. Pyotr Shchukin, a renowned Moscow merchant and collector, built them for his own museum. The very first building (1893), the so-called Old Museum, housed Shchukin's collection of paintings and antiques. Today, it houses the administration of the Biological Museum, and the building has retained its architectural value.

Elena Mikheecheva explains that the museum has a talisman inherited from the Shchukin estate: "The creature depicted on the large medallion of the old museum is a very interesting biological specimen, a hybrid of three creatures: it has wings like a pegasus, a horn like a unicorn, and a tail like a snake or a lion. Art historians suggested that this creature is called an alicorn."

Pyotr Shchukin, along with architect Boris Freidenberg, went on expeditions to the Russian North. Many architectural and artistic designs originate from those places. The tiles decorating the old museum are copied from those in the ancient Church of St. John the Baptist in Yaroslavl.

New space

K.A. Timiryazev Biological Museum— is not just history frozen within the walls of the mansions on Malaya Gruzinskaya Street. It is developing dynamically, and the main proof of this is the large-scale project the museum is implementing. This summer, the Biocluster project was launched—a fundamentally new open museum space and research center, unique in Russia.

Currently, the Biocluster occupies two VDNKh pavilions, and in the future, there will be five, along with a greenhouse-laboratory. The idea strikingly echoes Boris Zavadovsky's original concept, who envisioned a space where scientific theory would be directly combined with practical experience for the public. Visitors to the Biocluster can encounter dinosaurs or explore the wondrous world of insects, participate in plant experiments in the greenhouse-laboratory, or learn how to grow garden flowers.

You can now visit two key sites at the Biocluster. In pavilion No. 29 Floriculture and landscaping The exhibition "Morphogenesis. Third Nature," organized in collaboration with contemporary Russian artists, is located in Pavilion No. 31, "Geology," where a large-scale exhibition is on display. "12 Signs of Life"All sections—from "Unity of Chemical Composition" to "Reproduction"—are illustrated by works of science art. A highlight of the exhibition is the robot guide Professor Boris Zemelkin, who leads visitors on tours.

Service capabilities Mospitometz The mos.ru portal has been expanded. Now, users can not only choose a pet from a city shelter but also receive care recommendations, learn more about programs supporting homeless animals, and join these projects. The service features information about the services offered by city veterinary clinics and helpful articles on animal hygiene, microchipping, and much more. The service also helps users schedule appointments with veterinarians and other pet care professionals. A special section, "Helping Homeless Animals," explains how to volunteer at city shelters.

"The Mospitometz service offers future pet owners a range of useful solutions. It helps them find a pet from a shelter, learn about the services offered by city veterinary clinics, book appointments or grooming appointments, and receive detailed care instructions. A special quiz helps users determine which animals they are compatible with, allowing them to make an informed decision and lay the foundation for a long and happy life together. For those who aren't yet ready to adopt a pet but want to help, the service has created a section on supporting homeless animals, where they can learn about volunteering or making a donation," the Moscow city's press service reported.

Department of Information Technology.

The Mospitometz super service contains dozens of useful instructions, including information on preparing for the appearance of a pet in a home. Specialists have developed a step-by-step plan that details how to set up a home, what documents are needed, and how to help the animal adjust. The instructions also explain the specifics of caring for shelter pets and the veterinary procedures you should schedule first.

There are 24 state-run veterinary clinics in Moscow, including those specializing in exotic animal care. In a separate section You can learn more about their services and which specialist to contact if needed, how to make an appointment with a doctor and receive veterinary care at home, as well as view a map of clinics and find the nearest facility.

Another chapter Provides detailed information on pet hygiene procedures and grooming appointments if owners want to entrust their pet to professionals. And in the section Helping homeless animals Information on how to become a volunteer at city shelters, marked on the interactive map, is available. You can also support the shelters by making a donation through Charity service on mos.ru, which features non-profit organizations helping cats and dogs. You can quickly access its page directly from this section.

The Mospitometz service launched in October of this year. One of its key features is to help prospective owners choose a cat or dog by reviewing profiles of existing pets and scheduling a visit to the shelter.

"Currently, the Mospitometz catalog contains over a thousand profiles of dogs and cats living in 13 city shelters. All animals are socialized, microchipped, and vaccinated, so future owners won't have to waste time with a veterinarian. Pets are handed over with documents detailing all vaccinations, microchip, gender, weight, color, and other characteristics," noted the press service of the Moscow City Services Complex.

When choosing a pet, users can use filters to select the animal's type (cat or dog) and specify its gender, age, size, coat length, and color. Additionally, prospective owners can take a special quiz to help them find the most suitable four-legged friend. The service asks users to answer six questions—it takes no more than two minutes.

Each pet's page features photos, a description of their appearance and personality, and shelter contact information. To meet the animal you like, click the "Book Now" button and provide your information. Only authorized mos.ru users with a standard or full account can do this. After receiving your request, a shelter staff member will contact you to confirm the date and time of the visit. The service will also automatically suggest profiles of other pets similar to your chosen one.

If after meeting at the shelter a person decides to take the little tail they like home, they will be asked to sign agreement, which outlines the owner's rights and responsibilities—three days are allotted for this. This will allow the future owner to weigh their decision and prepare for the pet's arrival.

The creation, development and operation of e-government infrastructure, including the provision of mass socially significant services, as well as other services in electronic form, corresponds to the objectives of the national project Data Economy and the Moscow regional project "Digital Public Administration."

Translation. Region: Russian Federation –

Source: Peter the Great St. Petersburg Polytechnic University –

An important disclaimer is at the bottom of this article.

The "Engineering League of St. Petersburg," an intensive educational program for schoolchildren, concluded at the Polytechnic University. Over 100 young engineers worked on their projects, which they presented at the final conference. The program was organized with the support of the St. Petersburg Employment Center.

Over the course of a month, participants immersed themselves in the world of modern technical creativity, going from idea to working prototype. Each project was supervised by experienced mentors from among Polytechnic University faculty and students.

Andrey Shirokikh, an engineer at the I. I. Kirillov Turbine Engineering Laboratory, and Nikita Izbyakov, an engineer at the Higher School of Power Engineering, taught the "3D Modeling of Aircraft" course. Participants mastered 3D modeling in KOMPAS-3D, working their way from designing the main components of an aircraft (chassis, fuselage, wings) to final model assembly, with a particular focus on additive manufacturing and 3D printing.

The "Virtual Designer" course focused on the fundamentals of shipbuilding. Together with Alexander Tupikov, an assistant at the Higher School of Mechanical Engineering, the students learned the basics, mastered 3D modeling, and learned how to calculate catamaran propeller parameters. This became the final project for the KOMPAS-3D modeling and propeller calculation course.

The "Circuitry" program focused on the fundamentals of designing devices using CAD and 3D printing, as well as practical application of Arduino programming. Under the guidance of Alexander Cheledkov, a student at the Institute of Mechanical Engineering, Materials, and Transport, the students created a smart lighting system and a home delivery robot for transporting small loads.

Participants in the "Warehouse Industrial Robotics" program, led by Ivan Baranov, a student at the Institute of Computer Science, completed a comprehensive study of modern warehouse technologies. The program included CAD design and process automation programming, which enabled the development of a robotic loader for the smart warehouse of the future, capable of optimizing logistics operations.

The "Prototyping and Circuit Design Fundamentals" course was taught by Maxim Ruzakov, a research assistant in the Industrial Stream Data Processing Systems laboratory. The program included a sequential dive into the full device creation cycle: 3D modeling in Kompas-3D, circuit design, working with microcontrollers, and Arduino programming. The final project was a car with a collision avoidance system.

The 3D Printing and Prototyping course was taught by student Artem Lekhnovich. Participants learned 3D modeling and slicer tools, applying their knowledge to project work. The end result was a machine for producing filament from recycled plastic, addressing the challenge of sustainable development.

At the final conference, the best projects were presented, selected from each of the six areas. Participants presented functioning prototypes, demonstrating not only technical skills but also their ability to work in a team, solve complex engineering problems, and effectively present their developments to experts.

"The Engineering League is much more than just an intensive educational program. It's a launching pad for future engineers," commented Artem Egupov, Director of the Applicant Services Center. "Here, students gained invaluable project-based experience, worked with modern equipment, and saw their theoretical knowledge materialize into real devices. We don't just teach them engineering; we help them believe in themselves and understand that they are the future leaders who will shape the technological development of our country."

The project's main idea is to give young people the opportunity to immerse themselves in the world of technology and engineering solutions right during class. Classes held at the Polytechnic University created the necessary atmosphere and provided access to modern equipment. This helps clearly demonstrate that the engineering field is developing dynamically and is full of interesting challenges. The project's main goal is to demonstrate to young people the appeal of technical specialties and inspire them to choose the professions of the future. "That's why I consider our initiative important and am pleased with its successful implementation," noted Anna Shakhova, Head of the Career Development and Professional Development Department at the St. Petersburg Employment Center.

All participants received certificates, and the authors of the best projects were awarded diplomas and prizes. The "Engineering League of St. Petersburg" project has proven its effectiveness in early career guidance and developing a talent pool for high-tech industries.

The 2nd Belarusian-Russian Media Forum, entitled "The Great Victory – Unity and Memory of Generations," concluded in Mogilev. It brought together over 100 students from 23 universities across the Union State. In his address, Deputy Minister of Science and Higher Education of the Russian Federation Konstantin Mogilevsky emphasized that the memory of the Great Victory is the spiritual support of nations and a source of resilience. He urged the participants to delve deeply into historical materials to create reliable media content and expressed hope that the forum would provide them with an opportunity to gain new knowledge and make new friends.

Mikhail Lustenkov, Rector of the Belarusian-Russian University, noted: "The forum participants face several goals. To reconnect with the events that took place 80 years ago and to recognize the significance of Victory. After all, without it, we wouldn't exist."

A team from the Higher School of International Relations at the SPbPU Institute of Humanities, consisting of Daria Zemtsova, Kirill Grebenkov, and Mikhail Kornev, presented their project on preserving historical memory. Over the course of three days, they attended master classes and lectures, discussed with renowned experts, shared experiences, and collaborated on their own projects dedicated to preserving the historical memory of the Great Patriotic War. On the final day, the media forum participants presented their work to the jury. The project by the Higher School of International Relations students came in second.

Daria Zemtsova shared her impressions: "The media forum gave us the opportunity to prove ourselves in the media sphere. We worked on a media project dedicated to the sensitive topic of the Great Patriotic War, interacted with renowned speakers, and interviewed them. The new skills we acquired are invaluable in today's reality."

An NSU graduate student demonstrated for the first time the influence of various compounds with a similar structure on the formation of new forms of carbamazepine.

Translation. Region: Russian Federation –

Source: Novosibirsk State University –

An important disclaimer is at the bottom of this article.

The template effect of a small amount of additives of compounds with a similar structure (various saturated carboxylic acids and alkanes) on the process of self-assembly and crystallization of the channel trigonal structure of carbamazepine using a mechanochemical approach, crystallization in solution and melt was demonstrated by a first-year master's student in the Chemistry program and the training profile "Methodological support for physicochemical studies of condensed phases" Faculty of Natural Sciences of Novosibirsk State University (NSU Natural Sciences Department) Daria Zheltikova, under the supervision of Evgeny Losev, a research fellow at the Boreskov Institute of Catalysis SB RAS, senior lecturer in the Department of Solid State Chemistry at the NSU Natural Sciences Department, and candidate of chemical sciences. The key focus of her research was studying the phenomenon of polymorphism and the conditions for the formation of new solid forms of medicinal compounds, particularly carbamazepine, as well as methods for their controlled production. The effect of the compounds examined in the study on carbamazepine had never been previously studied.

Polymorphism is the ability of the same substance to exist in different crystal structures (polymorphic modifications). These structures differ in the arrangement of atoms (or molecules) and may have different physicochemical properties (e.g., solubility, melting points).

"The pharmaceutical industry is focused on studying the conditions for the formation of new crystalline forms of medicinal compounds, investigating their structures and physicochemical properties, and their interconversions. These processes address such important issues as the reproducibility of obtaining the desired substances, establishing the stability of drugs prone to polymorphism, and improving fundamentally important pharmaceutical characteristics: dissolution rate, bioavailability, storage stability, hygroscopicity, and other properties. To screen new crystalline forms, we primarily used a mechanochemical approach. This is a common method for screening the conditions for obtaining new solid forms of molecular compounds. Thanks to the wide range of parameters available for mechanochemical experiments, researchers can comprehensively study a selected system and draw conclusions about the putative mechanism of the processes occurring during the experiment. In recent years, mechanochemical reactions and transformations initiated by mechanical stress have been actively studied using various in situ methods using synchrotron radiation," explained Daria Zheltikova.

The young researcher's object of study was carbamazepine, a drug with antiepileptic and anticonvulsant properties, widely used in the treatment of nervous system disorders. According to the biopharmaceutical classification system, carbamazepine belongs to class II drugs, meaning it has low solubility in aqueous solutions and high intestinal permeability. Currently, five polymorphic modifications of this drug are known, which is quite unique and places carbamazepine in the class of highly polymorphic molecular compounds. Each polymorphic modification has a different crystal structure and molecular packing. In 1987, polymorphic modification II of carbamazepine, which has a trigonal space symmetry group, was first isolated and characterized. A distinctive feature of the crystalline structure of this form is the presence of extended tubular voids (channels) formed by the CH groups of the benzene fragments of the carbamazepine molecules. This substance is a good model object for studying the influence of experimental parameters on the selective production of specific polymorphic modifications and crystalline forms. The knowledge and patterns gained can be further transferred to other systems prone to polymorphism.

— The trigonal structure of carbamazepine, since its elucidation in 1987 and for several decades, was considered a polymorph. However, using a combination of physicochemical methods, it was recently established that the trigonal structure, which should have consisted solely of carbamazepine molecules, is a host-guest inclusion compound, where the carbamazepine molecules form a channel-type framework with solvent molecules embedded within the voids. The inclusion molecules will vary depending on the experimental conditions. It is the inclusion molecules that stabilize the trigonal crystal structure and enable its formation. Currently known inclusion compounds of carbamazepine are characterized by the presence of a small number of guest molecules in a highly disordered state, making their study quite labor-intensive. Various inclusion bodies of the trigonal form of carbamazepine can be classified as clathrates—compounds in which molecules of one substance (the "guest") are trapped within the crystal lattice of another substance (the "host"). The host molecules form a framework, while the guest molecules are located within it and held in place by weak intermolecular interactions, explained Daria Zheltikova.

Research into carbamazepine polymorphism and its formation of various crystalline forms began quite some time ago and was conducted as part of several projects implemented over the years with support from the Russian Foundation for Basic Research, the Russian Science Foundation, and the Priority-2030 program. The results were published in peer-reviewed international journals. This study continues work conducted earlier in the previous stages of the NSU Physics Faculty's youth competition "X-ray, Synchrotron, and Neutron Methods of Interdisciplinary Research," with support from the Priority-2030 program.

The aim of this study is to optimize the conditions for obtaining single crystals of carbamazepine clathrates with various guest molecules using various crystallization techniques and their analysis using a set of physicochemical methods.

Such exploratory work, despite its significant fundamental component, often leads to the establishment of the existence of new, previously unknown polymorphic modifications of medicinal compounds, which has direct practical significance, and also establishes correlations between the parameters and results of crystallization experiments, which can be useful in the study of systems similar in structure and properties.

One of the new scientific results obtained in this study is the demonstration of the template effect of small amounts of structurally similar compounds on the self-assembly and crystallization of the channel trigonal structure of carbamazepine using various methods—a mechanochemical approach, solution crystallization, and melt crystallization. Saturated carboxylic acids and alkanes—compounds containing a long, unbranched carbon chain—were used as structurally similar compounds. The template effect observed in the preparation of carbamazepine clathrates is based on the ability of the template (in this case, various carboxylic acids and alkanes) to organize the reactant (carbamazepine) molecules around itself, enabling the formation of a seed cluster, which serves as a precursor for the targeted formation of the final crystalline structure. All newly obtained compounds are clathrates of the trigonal form of carbamazepine, that is, the structure of carbamazepine contains inclusion molecules of the corresponding acids and alkanes.

— Currently, we are focused on optimizing methods for obtaining single crystals of various carbamazepine clathrates for further study and investigation of their stability at elevated temperatures. We obtained nine clathrates with saturated carboxylic acids and alkanes under various conditions. Our study examined six carboxylic acids and three alkanes. We have focused on only a few compounds from each group, as obtaining single-crystal samples for each individual compound is quite labor-intensive due to differences in formation conditions and certain experimental details. The compounds obtained have an acicular morphology—in simpler terms, they are thin, needle-like crystals. In some cases, the needle size is so small that it precludes single-crystal X-ray diffraction analysis using laboratory diffractometers. For this reason, not all of them have had their crystal structures determined yet. We characterized compounds whose crystal structures had not been obtained using Raman and NMR spectroscopy, said Daria Zheltikova.

An important disclaimer is at the bottom of this article.

The Active Citizen project, in collaboration with the City of Ideas platform, launched a new voting format. A resident of the Yasenevo district proposed several initiatives for the development of the Moscow EcoPoints project.

The first proposal concerns the ability for citizens to monitor the status of recycling collection points, leave comments on their operations, and suggest new locations for containers.

The second suggestion is to add to the map portal Photos of the containers for each collection point. This will help Muscovites better navigate and understand what the eco-points look like and where they are located.

IN voting Citizens can fully support these ideas, make suggestions for their improvement, or leave the resolution of issues to the discretion of specialists.

The voting was prepared jointly with the capital Department of Nature Management and Environmental Protection.
