Faculty and students of the Department of Solid State Chemistry Faculty of Natural Sciences (FNS) of NSU participated in the International University of California, Santa Cruz, High Pressure Workshop on High-Pressure Crystallography (IUCr High Pressure Workshop). The workshop was held in Shanghai, China, from September 21 to 26.

The seminar program included presentations on various areas of high-pressure crystallography: from geological research and the analysis of superconducting materials to technical aspects such as the design of synchrotron and neutron stations. The event brought together high-pressure crystallography specialists from around the world, with 169 participants. A competition was held among the young scientists' submissions.

Elena Boldyreva, Professor of the Department of Solid State Chemistry at the NSU Department of Natural Sciences, presented an invited talk online. Poster presentations were presented by Nikita Bogdanov, Senior Lecturer in the Department; Svetlana Sharaya and Polina Kalinina, PhD students; and Grigory Zhdankin, Master's student at the Moscow Institute of Physical Chemistry and Physics. Nikita Bogdanov and Polina Kalinina's work was awarded prizes for the best work in the Young Scientists Competition and for the best talk. The talks presented research results, including those from Russian Science Foundation projects being implemented at NSU: "The Relationship Between Crystal Structure and Photoisomerization of Cobalt Pentaammine with Various Anions" (No. 24-22-00293) and "Structural Aspects of Ferroelectric and Piezoelectric Phase Transitions in Organic Crystals under High Pressure and Low Temperature Conditions" (No. 24-23-00410).

The conference included a tour of the Shanghai Synchrotron Radiation Facility, where participants were able to see the experimental stations designed for studying substances under high pressure. They also visited the HPSTAR Center for Advanced High-Pressure Science and Technology.

The participant shared their impressions:

Grigory Zhdankin, a second-year student of the master's program "Methodological Support for Physicochemical Studies of Condensed Phases" at the Department of Chemical Technology, Faculty of Natural Sciences, NSU:

I really enjoyed the diversity of the oral and poster presentations at the conference: from projects for synchrotron radiation stations designed to study substances under extreme conditions to research in mineralogy and the synthesis of new substances at high pressures (over two million atmospheres). I had the opportunity to interact in person with a large number of interesting people whom I had previously only known through their articles. This gave me a huge boost of motivation to continue my scientific work.

Shanghai itself turned out to be quite an interesting city for tourism. Between listening to presentations, we managed to visit several interesting places: Yuyuan Garden, the Shanghai Aquarium, Nanjing Road, and People's Square.

Polina Kalinina, first-year PhD student at the Faculty of Natural Sciences:

It was fascinating to interact with various scientists, both leading experts in high-pressure crystallography and emerging young researchers. It was also helpful to see firsthand how high pressures are applied in various fields of research—it broadens your horizons and inspires new research beyond your own. For example, I was particularly interested in the work investigating the composition of the Earth's mantle, as well as the work aimed at producing hexagonal diamond—lonsdaleite. It was gratifying to see the conference participants' interest in my work and that of my colleagues; there were many positive wishes and encouragement. I am very motivated when my work is interesting to people who are seeing it for the first time.

Svetlana Sharaya, 3rd year PhD student at the Faculty of Natural Sciences:

A huge number of presentations at the conference were devoted to synchrotron topics and the use of synchrotron radiation for high-pressure crystallography research. It was very interesting to hear the experiences of colleagues from China and other countries in setting up stations and conducting experiments using synchrotron radiation. This was useful for us, as the knowledge gained can be applied at the SKIF facility currently under construction in Koltsovo.

Furthermore, the conference featured presentations that weren't directly related to crystal study methods, but focused on the fundamentals of mathematical crystallography. This was useful for me as a budding scientist. I particularly remember the presentation on predicting crystal symmetry before and after a phase transition, taking into account the structure and properties based on group theory.

The permanent exhibition "Mesozoic: Continental Flora and Fauna" has been expanded with a new display case featuring specimens of Cretaceous lake fauna—remains of bony fish, insects, and crustaceans. These specimens were collected by staff from the "Evolution of the Earth" Scientific and Educational Center. Faculty of Geology and Geophysics of Novosibirsk State University and the A.A. Trofimuk Institute of Petroleum Geology and Geophysics (IPGG) of the Siberian Branch of the Russian Academy of Sciences during expeditions to the Trans-Baikal Territory. The exhibition also includes finds from China, provided by Igor Kosenko, Associate Professor of the Department of Historical Geology and Paleontology at NSU's GGG. The uniqueness of all the specimens lies in their excellent preservation—the structure of these prehistoric creatures can be seen in exquisite detail, even with the naked eye.

The new display case presents animals belonging to the Jehol fauna. These are the fossil remains of feathered dinosaurs, birds, mammals, and plants, found in large numbers in the Lower Cretaceous deposits of northeastern China. Such localities are called lagerstätten. This is a special type of fossil burial that preserves not only the hard parts of skeletal forms but also impressions of soft tissue. Lower Cretaceous deposits containing the remains of the Jehol biota are very widespread—from Transbaikalia, Russia, in the north and Japan in the east, to Guangdong Province, China, in the south and the Xinjiang Uyghur Autonomous Region of China. Deposits characterized by typical representatives of the Jehol biota are widespread in Transbaikalia. These include the remains of crustaceans (Eosestheria conchostracans), insects (Ephemeropsis mayfly larvae), and bony fishes (Lycoptera). All of these prehistoric lake animals are on display in a new display case, said Vsevolod Efremenko, an engineer at the Evolution of the Earth Research Center and a junior researcher at the Institute of Petroleum Geology and Geophysics (IPGG SB RAS).

The Jehol Biota is a distinct lake fauna and flora characteristic of Asia. It encompasses China, Mongolia, the Transbaikal Territory, and parts of Korea. This fauna has been known for some time and was first described from finds made in the Transbaikal Territory. However, it gained notoriety and its current name after the discovery of feathered dinosaur footprints in China. Scientists from the Novosibirsk State University Geological and Geophysical Institute and the Institute of Petroleum Geology and Geophysics (IPGG SB RAS) have been studying the Jehol Biota in the Transbaikal Territory since 2021. An expeditionary team for paleontological research in the Transbaikal Territory was formed four times—in 2021, 2022, 2024, and 2025. The materials presented in the exhibition were collected during the 2021 and 2024 expeditions. A new expedition is planned for 2026.

The new display case features specimens of Jehol lake fauna from Transbaikal and China. The most striking, of course, are the fish. Among them is an ancient paddlefish—a sturgeon-like fish called Protopsephurus, which appeared in the Mesozoic era and spread across the planet. Also on display is a remarkably well-preserved bony fish called Lycoptera, quite common in the Mesozoic era. The specimen clearly displays scales that have retained their original position. For this reason, even the lateral line—a sensory organ that runs along the body—is visible on the fish's body. It senses the movement and vibrations of the water, helping the fish navigate, navigate obstacles, move in a school, and avoid predators.

Fishes of the genus Lycoptera were widespread across Asia approximately 120 million years ago, and paleontologists encounter such finds quite frequently. However, many specimens often have scales that are displaced and the lateral line is destroyed. Here, however, it is clearly visible. This means that the scales remained in place from the moment of death until burial, and the fish itself was preserved in ideal conditions. Thanks to these conditions, another specimen was also perfectly preserved—the largest fish skeleton on display. This is an Irenichthys, with a body length of approximately 15-18 cm. This is the largest complete skeleton of this species we have found—these fish typically do not grow to such a size. All the bones of the skeleton and scales are clearly visible, and the structure of the skull is clearly visible. A detailed description of the entire species could be compiled from this specimen. This specimen, like the previous one, was preserved in ideal conditions, which is why it is so beautifully preserved. But other fish of the same species, whose imprints are on display, were less fortunate—they are slightly deformed, their scales damaged. "It's likely that optimal conditions were periodically disrupted in the places where they were preserved," explained Vsevolod Efremenko.

In addition to Cretaceous fish, the exhibition also features crustaceans and insects: shield bugs, mayfly larvae, and beetles. They are as well preserved as the fish—all body segments, legs, tiny claws of small crustaceans, and antennae are clearly visible. Some insects even retain egg clutches and the internal structure of their bodies. A magnifying glass is sufficient to fully appreciate such fine details, but they are also visible to the naked eye. The silhouettes of mayflies with their triple tails are slightly less distinct on the stone slabs. On some specimens, the outlines of small fish can be seen among the numerous crustaceans.

— Locations where creatures that lived for tens or hundreds of millions of years have been preserved in ideal conditions and in wide diversity are called lagerstätt. For paleontologists, these are real treasure troves. There are several of them in Transbaikalia, and we worked at these locations. It should be noted that the lakes themselves are no longer preserved; we are working with the fossilized sediments of these paleolakes. In one such ancient reservoir, a large variety of fish was preserved in abundance, while in another, for some reason, they were not found, but many shieldfish and insects were found. To ensure such preservation for living beings and “preserve” them for many tens of millions of years, a number of conditions must be met. The animal must end up on the muddy bottom of the reservoir in an oxygen-free environment. An important condition is the absence of predators or scavengers who would eat the remains of a dead animal. In these places there should be no currents or other hydrodynamics that could disrupt the integrity of the remains. In addition, they should be gradually covered with sediment to protect them from adverse environmental influences. It is in such places that today one can study the ecology, paleobiology, food chains, and lifestyle of the lake inhabitants of the Mesozoic. Lagerstätts are also valuable because such unique specimens, which are presented in our exhibition, can be found by paleontologists without much difficulty, whereas at ordinary excavation sites the search for ancient creatures is a rather labor-intensive, lengthy task and does not guarantee success. The number of exhibits on our new showcase will be replenished, as we plan to continue to participate in excavations in the Transbaikal region,” said Vsevolod Efremenko.

The exhibition dedicated to the continental flora and fauna of the Mesozoic was recently supplemented by an installation of fragments of fossilized tree trunks. It aims to reflect the Mesozoic era as the kingdom of gymnosperms, which then reached its peak of biodiversity and distribution. Modern conifers are a well-known example of such plants. However, by the mid-Cretaceous, the first flowering plants appeared, which, by geological standards, began to displace their competitors quite quickly. Therefore, the diet of herbivorous dinosaurs at the end of the Cretaceous was already radically different from that of their Jurassic predecessors.

"When assembling the installation, we used more ancient, late Paleozoic fragments of fossilized cordaite trunks (Cordaitales) from Kuzbass, approximately 300 million years old, as the Evolution of the Earth Research Center has accumulated a large number of similar specimens, collected over the years by staff from the Geological and Geophysical Faculty of NSU. Cordaites are also gymnosperms, specifically primitive conifers. These were mighty trees, as tall as modern pines and cedars, but with large, lanceolate leaves that were shed seasonally," explained Alexander Igolnikov, head of the Evolution of the Earth Research Center.

The Novosibirsk Region boasts one of the most developed IT training ecosystems in the country. Thousands of IT specialists and engineers graduate annually from 10 universities and 14 colleges in the region. Many of them are in demand at leading Russian and international companies and become proponents of the latest technologies. This was announced by Elena Proforuk, head of the Novosibirsk Region Ministry of Digital Development, at a press briefing that kicked off the "Impulse T1" conference in Novosibirsk. The event took place on the new campus of Novosibirsk State University.

Novosibirsk has traditionally been among Russia's IT leaders. Today, the sector employs over 30,000 specialists, and approximately 3,000 IT companies are registered in the region. In 2025, the digital industry's contribution to the gross regional product reached 4%, exceeding the Russian average. In the first six months, the local IT sector contributed over 7 billion rubles to the budget, with revenue and tax revenues increasing by 20-30%.

"Our main competitive advantage is our highly qualified workforce. The region boasts a unique combination of education, science, and industry, which ensures dynamic growth in the IT sector and the digital transformation of the entire economy, as well as provides young people with opportunities to successfully find employment in their home region," said Elena Proforuk, head of the Novosibirsk Region Ministry of Digital Development, Communications, and Mass Media project office.

Mikhail Knigin, Executive Director of T1 Integration, noted that Novosibirsk is one of the key regions for the T1 IT holding company. "Today, we have over 500 employees in Novosibirsk, and the team has grown by 37% over the past year. This demonstrates the growing potential of the region's engineering workforce and the effectiveness of the practice-oriented approach to training specialists, which is achieved through the collaboration between educational institutions and businesses," Mikhail Knigin emphasized.

This year, NSU launched a bachelor's degree program in applied artificial intelligence: 176 students from more than 20 regions are studying not only technical disciplines and programming but also IT project management. All students are participating in the development of real-world solutions for Russian businesses. The program's anchor industry partner is the IT holding T1. As part of the program's training, the company provides students with access to its own IT solutions. In 2026, NSU will implement the Cybox platform for a full cycle of working with machine learning models, which will be used both in education and for research purposes.

"Artificial intelligence isn't a privilege for a select few, but a tool that should be taught to students from their first year. The sooner we introduce practical and project-based learning, the faster young specialists become marketable," says Alexey Okunev, Director of the NSU Institute of Intelligent Robotics.

As part of the conference, IT holding T1 also held a hackathon across two tracks: "Digital Dress Code: Creating Local ML Video Segmentation Modules and a Personalized Background Generator"; and "CodeMetrics: Developing a System for Automatically Assessing Team Performance Through Git Metrics Analysis." Over 630 students registered for the competition, with 10 teams reaching the finals. Third place in the "Digital Dress Code" track was taken by first-year students from the Institute of Intelligent Robotics, studying in the new bachelor's degree program "Applied Artificial Intelligence," supported by IT holding T1 and supervised by the Analytical Center under the Government of the Russian Federation.

A cooperation agreement was also signed between NSU and the IT holding T1 in the field of education. Key areas include improving the quality of IT education, taking into account current practical needs, and developing students' research activities in the field of AI.

The event demonstrated that Novosibirsk is becoming not only a magnet for high-tech companies, but also a true laboratory for new educational solutions, forming the foundation for Russia's digital future.

Novosibirsk, October 28, 2025: Researchers at the National Technology Initiative (NTI) Competence Center for Modeling and Development of New Functional Materials with Predetermined Properties (CNFM) at NSU have developed a concentrate based on multi-walled carbon nanotubes (MWCNTs) that can improve the properties of silicone rubbers. This new solution opens up potential applications in a wide range of industries, from medicine to oil and gas production. The development was funded by the National Technology Initiative Foundation.

"We've filed a Russian patent application for the invention 'concentrate composition and method for producing it.' This material is used to modify silicones, both low- and high-viscosity. It increases strength and imparts electrically conductive properties to the material, which were previously difficult to achieve," explained Andrey Skuratov, a research fellow at the NSU Center for Scientific Physics and Mathematics. Silicone rubbers are widely used in industry and medicine: they are used to make O-rings, gaskets, metal coatings, conveyor belts, and medical equipment components.

Standard methods for introducing nanotubes into silicone do not produce the desired results. According to researchers, simply adding nanotube powder to the material causes it to lose its properties, degrade more quickly, and the claimed antistatic properties are not realized. The NSU Center for Scientific Physics and Microphysics team proposed a fundamentally different approach: the nanotubes are pre-treated and distributed throughout the concentrate. This prevents the formation of agglomerates and evenly integrates them into the silicone structure.

"We use a special method in which the nanotubes are 'untangled' and dispersed. The result is a working product—a concentrate. Using this nanotube concentrate can be easily integrated into the silicone rubber manufacturing process without changing it, making our development convenient for industrial applications," explained Andrey Skuratov.

One of the key advantages of the new materials is the ability to finely tune their electrical conductivity by adjusting the concentration of MWCNTs in the silicone matrix. The effective range of nanotube content is from 0.2 to 0.8% by weight, enabling the production of materials with tailored electrical characteristics without compromising their elasticity or strength. This approach allows for tailoring the material to specific application requirements, from antistatic to conductive properties. This is particularly important in medicine, as static electricity can attract dust and contaminate the surface of products. In the oil, gas, and mining industries, controlled electrical conductivity provides an antistatic effect, preventing sparking and improving equipment safety. Furthermore, the introduction of MWCNTs significantly increases the mechanical strength of silicone: the developers were able to increase the elastic modulus and tear resistance by 25–35%. As a result, the products become more durable and more resistant to mechanical stress, including friction and contact with metal surfaces.

The developed nanotube-based concentrate paves the way for the creation of so-called "smart" silicone materials with tailored properties. These materials can be used to manufacture components for the automotive, space, and mining industries, as well as medical equipment and conveyor systems.

"We were able to not only confirm the improvement in physical properties but also demonstrate that the material becomes functionally flexible. It can be used to adjust its electrical properties to meet customer needs. This opens up a wide range of applications," the scientist noted.

Russian scientists have developed a new combined approach aimed at identifying the binding sites of drugs used in photodynamic oncotherapy with the protein responsible for drug transport in the human body. This approach will accelerate the search for the most effective cancer drugs and minimize side effects on patients. This study was conducted by a team of scientists from Novosibirsk State University, the International Tomography Center of the Siberian Branch of the Russian Academy of Sciences, and staff from the Russian Technological University MIREA.

The results of the study were published in Journal of the American Chemical SocietyThe mere fact of publication in such a prestigious and highly cited journal is already considered a success for young researchers, and this article was accepted for publication in the "Editor's Choice" section, demonstrating the recognition of the research by the international professional community. The publication's lead author, Mikhail Kolokolov, a second-year graduate student in the Department of Chemical and Biological Physics at the NSU Physics Faculty and a junior researcher at the Electron Paramagnetic Resonance Laboratory of the International Tomography Center, received the prestigious youth award from the International Society for EPR Spectroscopy for best scientific paper. The young scientist conducted his research with fourth-year graduate student Natalia Sannikova from the same department, under the supervision of Olesya Krumkacheva, Doctor of Physical and Mathematical Sciences.

When medications enter the human body, they primarily bind to proteins in the blood. The effectiveness of a particular drug depends on its binding to serum albumin, a protein found in blood plasma responsible for transporting substances within the body. The degree of binding to this protein significantly influences the drug's action. If binding is too strong, the drug's concentration in the blood will be reduced, while if binding is weak, the drug may be unevenly distributed throughout the body or even destroyed without achieving its intended effect.

“To create an effective drug and control its binding to the transport protein, it is important to know where on the protein its molecules will attach. Identifying such sites will lead to understanding the mechanism of action of drugs, predicting side effects and identifying the causes of drug resistance in some patients. However, traditional methods of structural biology are not effective enough if there are several binding sites or the interaction of the drug with the protein surface is unstable. Then researchers use the molecular modeling method, but its results are not enough, since drugs often bind to the protein in several places. Thus, several small drug molecules can be attached to one protein simultaneously and at different sites. Thus, many variants of the structure of such complexes are obtained, which becomes difficult to take into account by molecular modeling. We proposed our own combined approach that allows us to measure the distance between various elements of the complex and use them to obtain its structure. Previously used methods produce average values, but in our case it is possible to achieve atomic precision in measuring the distribution of distances between binding sites, “see” all possible conformations (that is, the spatial arrangements of atoms in a molecule of a certain configuration) and find places where small molecules of a substance bind to a protein. This is the most important element of our work. In our approach, we measure distances within the complex using spin labels. A special small molecule containing an unpaired spin is selectively introduced into a region of the protein that we know. After binding the protein to the drug, we can measure the spin-spin distances between the spin label and the drug molecules on the protein,” explained Mikhail Kolokolov.

In their approach, the scientists combined molecular modeling methods with experimental data obtained using electron paramagnetic resonance, which allows the structure of compounds to be determined based on their microwave absorption. They first identified potential drug-protein binding sites using calculations, then conducted EPR spectroscopy studies, and then applied the experimental results and computer calculations to refine the configuration of these sites. This work was carried out by Mikhail Kolokolov and Natalia Sannikova, graduate students from the NSU Physics Department and junior research fellows at the EPR Laboratory of the International Tomography Center. It was discovered that binding for various types of photosensitizers can occur at non-standard sites on albumin and at several sites simultaneously.

"In theory, you can even determine where a molecule binds to a protein without any experiments, simply using computational methods. However, in practice, it turns out that these methods lead to significant inaccuracies and even errors because the calculation algorithms are relatively simplified. For this reason, scientists are often unsure of their results. Furthermore, computational methods can yield several possible binding sites and their locations. And often, from a calculation standpoint, these options are equally likely. The question is which one is correct. For this reason, the computational method is not precise enough and should not be relied upon entirely. However, it is still useful because it provides direction for experimental research, allowing us to narrow the range of possible binding sites. Thanks to this, we can use our experimental distances, which we are confident in, along with the computational methods, to determine the presence of a molecule on a protein with sufficient accuracy," explained Mikhail Kolokolov.

The scientists tested their combined approach by studying the binding of albumin to photosensitizers.

Photosensitizers are natural or synthetic substances that are used in medicine, for example in photodynamic therapy (PDT), where they accumulate in pathological cells and are activated when irradiated with light, causing their death.

Photodynamic oncotherapy is considered a very promising method because, unlike traditional chemotherapy, it targets only the tumors that are exposed to light. However, this cancer treatment method is currently not widely used due to the imperfections of photosensitizers. Scientists are faced with the challenge of improving their light absorption, diffusion throughout the body, and accumulation in tumors. This study of the albumin-binding sites of photosensitizers is important for further improving their diffusion throughout the body and increasing their concentration in tumors, which will contribute to increased therapeutic efficacy. Therefore, work in this area has significant clinical significance.

Scientists have identified the locations of binding sites for seven compounds whose structural interactions with albumin were previously unclear. The new approach demonstrated that binding can occur at non-standard sites on albumin and at multiple sites simultaneously for different types of photosensitizers.

The scientists tested the effectiveness of their combined approach using several photosensitizers. To demonstrate different binding mechanisms, they used compounds whose molecules had different electrical charges—negative, positive, and neutral. It turned out that, depending on this charge, they bind differently to the protein, which in this case was negatively charged. Molecules with a positive or neutral charge "sit" on the negatively charged surface of the protein and form an unstable bond—they can temporarily detach and reattach.

Negatively charged molecules behave differently—they penetrate pockets on the protein surface and remain there stably. However, in this case, their size plays a key role. Relatively small molecules fit completely into these pockets and formed very effective binding, while larger molecules behave differently.

Experiments have shown that the smaller the molecule and the more completely it fits into these pockets, the higher the site population. Experiments with larger molecules that fit less freely into these pockets yield lower populations and less effective binding. The researchers observed these processes directly in experiments. This molecular behavior is logical, but computational methods don't account for it. While they can determine how a molecule binds to a protein, they don't determine how this affects the protein itself. If small molecules fit freely into the pocket, no significant changes occur. However, large molecules can alter the protein structure. Computational methods often don't capture this, but the researchers corrected these errors and inaccuracies through experiments.

"Throughout all our experiments in this study, we demonstrated with atomic precision where the molecules of these compounds bind to albumin, which is undoubtedly a novelty in terms of photostabilizer development. The combined approach we developed will make the analysis of anticancer compounds significantly more accurate, and the development of new oncotherapy drugs simpler and faster. By combining computer analysis and electron paramagnetic resonance data, we were able to significantly reduce the number of labor-intensive calculations and experiments, simplifying the determination of interactions between albumin and photosensitizers. We believe our work will enable us to predict the most promising compounds for photodynamic anticancer therapy. We now plan to apply our approach to study how photosensitizers bind to DNA molecules," explained Mikhail Kolokolov.

Scientists from the Laboratory of Nuclear and Innovative Medicine (LNIM) have begun a tomographic study of three mammoth tusks provided for study by the Department of Mammoth Fauna Studies of the Academy of Sciences of the Republic of Sakha (Yakutia). Faculty of Physics of Novosibirsk State UniversityThe next step will be radiocarbon dating of these artifacts, which will be carried out in NSU-NSC Accelerator Mass Spectrometry Center as part of the project Institute of Medicine and Medical Technologies The Priority 2030 program is currently underway. The objects of study—three mammoth tusks with various defects—were discovered several years ago in the Abyisky District, on the Tirekhtyakh and Badyarikha rivers in the Sakha Republic (Yakutia). Now, using high-tech research methods, scientists will determine the cause of the pathologies, determine the age of these paleontological finds, and identify the diet, geographic location, and migration patterns of these megafauna. The scientists claim that NSU has created optimal conditions for such research, housing the only low-voltage accelerator mass spectrometer in Russia and the only CT scanner in Siberia certified for animal studies and scientific research.

The scanned samples are mammoth tusks containing structural changes—significant deviations in shape and size, as well as abnormalities in tusk formation, clearly visible externally. The first sample clearly shows transverse "ring-shaped" constrictions of varying severity, indicating slowed or stagnant tusk growth. The second sample contains areas of nodular or irregular dentin growth. The third sample is very different from the previous ones, both in size—it is significantly smaller than normal-sized tusks—and in structure: the central portion of its cross-section differs from that normal for woolly mammoths; the dentin appears excessively dense and does not form the characteristic concentric layers. Furthermore, these samples also exhibit other types of pathologies not yet described in the scientific literature.

"Until now, there has been virtually no study of mammoth tusk pathologies worldwide. In Russia, only a few papers have been published comparing isotopic ratios in diseased and healthy tusks, and elemental analysis has been performed. At NSU, the work begins with studying the internal structure of diseased (aberrant) tusks, followed by an examination of the isotopic composition and the hereditary causes of such tusks. We chose NSU as a partner due to its highly qualified specialists in various fields and the availability of equipment. Such research is pioneering, and its importance is difficult to overestimate," commented Albert Vasilyevich Protopopov, Doctor of Biological Sciences and Head of the Mammoth Fauna Research Department at the Academy of Sciences of the Republic of Sakha (Yakutia).

In modern archaeology and paleontology, computed tomography (CT) has become an indispensable non-destructive method. For unique finds like the tusks from Yakutia, CT is a "digital scalpel," allowing one to peer inside the object and study its hidden structure without disturbing the original. The method provides a three-dimensional image of the external and internal structures, as well as information about the age, diet, and seasonal migrations of the animal. Its main value, however, lies in the detection of hidden pathologies that occurred during life, such as fractures, diseases, and injuries.

"The particular significance of our research lies in the combination of archaeology and preclinical veterinary diagnostic experience. A database of modern animal pathologies serves as a benchmark for interpreting injuries in fossil remains. By comparing the nature of the injuries, we can not only determine the probable cause of death of an individual but also reconstruct the environmental stresses experienced by the population—from competition for resources to climate change. This allows us to transform mammoth ivory into a detailed chronicle of its life and habitat," explains Vladimir Vladimirovich Kanygin, Head of the NSU Laboratory of Mammoth Illegibility and Evolution.

In the future, they plan to compare CT images of mammoth and elephant tusks to determine their similarity. Moreover, the laboratory's conditions allow for the study of more than just the tusks and skeletal remains of these large animals. LYAIM scientists hope to receive a well-preserved permafrost carcass of a baby mammoth from their colleagues in Yakutia for study. To do this, they could first conduct individual CT scans of its parts and then assemble all the images into a 3D computer reconstruction, allowing the object to be studied from any perspective.

The analysis of CT images of mammoth tusks will be carried out by a team of scientists led by Andrey Yuryevich Letyagin, Deputy Director for Research at the Institute of Cytology and Genetics of the Siberian Branch of the Russian Academy of Sciences, Deputy Head of the Institute of Clinical Experimental Lymphology for Research and Clinical Work, Doctor of Medical Sciences, Professor, and physician of the highest category in radiology. He is a leading expert at the Laboratory of Lymphatic Mechanics and Physics of the Faculty of Physics and Mammology of Novosibirsk State University. Together with other laboratory researchers, Andrey Yuryevich previously participated in the development of algorithms for the "Veterinarian Assistant" software module, designed to diagnose oncological diseases in domestic animals using CT images, and also participated in CT studies of archaeological finds conducted in the laboratory.

"We will be processing the CT images of the tusks' internal structure, paying attention to areas of destruction. We will certainly see some pathological changes of various origins, caused either by trauma or inflammatory degenerative processes. Much depends on the integrity of the bone structure, which we still need to determine, but one thing is clear: the work will be challenging due to the unusual nature of the objects being studied. Accessing the literature is practically impossible, as only a few articles on the topic exist to date. So, what we're seeing are CT images of objects that have never been studied before. We will have to develop our own protocol for conducting such studies within the technical capabilities we currently have," explained Andrey Yuryevich.

Computed tomography is only the initial stage of studying these unusual tusks. Scientists plan to conduct a comprehensive radiocarbon dating study, layer-by-layer analysis of isotopic and chemical composition, and histological analysis to determine the cause of the defects.

We want to know whether these abnormalities were the result of disease or environmental influences. It would be interesting to find any links between these pathologies and similar disorders in elephants, and even the possibility of their occurrence in humans. We suspect such a connection: mammoths became extinct at least several thousand years ago, yet the congenital defects and acquired diseases of modern elephants bear some similarities to those seen in these megafauna, which share a common ancestor with elephants. We would like to examine the situation from the perspective of disease evolution and assess how dental diseases change under the influence of various factors. Therefore, we have sent a request to zoologists and veterinarians involved in the study and treatment of elephants in India (the Center for Environmental Studies, Bangalore) and Thailand (the Center for Elephant and Wildlife Health, Faculty of Veterinary Medicine, Chiang Mai University) for the possibility of consultation. "Our Indian colleague has already responded and expressed great interest in working together," said Ekaterina Vasilyevna Parkhomchuk, Director of the NSU-NSC Accelerator Mass Spectrometry Center.

In the near future, the Isotope Research Laboratory of the Institute of Archaeology and Ethnography of the Siberian Branch of the Russian Academy of Sciences will conduct a layer-by-layer isotope analysis of all three tusks, while simultaneously preparing samples for dating. At the NSU-NSC Accelerator Mass Spectrometry Shared Use Center, the mammoths' lifespan will be determined using radiocarbon dating. Researchers will then study their elemental composition, which will reveal what the mammoths ate and how complete their diet was, the geographic locations they inhabited, and the directions they migrated. Using histological studies, the scientists hope to determine what diseases these megafauna suffered from, whether these diseases have disappeared in modern times or persist today, and whether they affect another, but surviving, lineage of elephants, a common ancestor of mammoths.

"We would be delighted to collaborate with researchers who possess other modern methods that allow us to approach the study of mammoth diseases. Until now, no one has seriously addressed this issue. Meanwhile, this is crucial in terms of contributing to the mammoth revival, which is no longer a fantasy but is becoming a reality. Our colleagues from Yakutia have established the World Mammoth Museum, where conditions are being created for the preservation and maximum prolongation of the life of all the unique specimens that are now being discovered as the permafrost melts," said Ekaterina Parkhomchuk.

Next, a histological examination of the tissues is planned. The NSU Laboratory of Nuclear and Innovative Medicine has modern, high-tech equipment that allows for ultrathin tissue sections to be prepared for microscopic examination using a digital scanner, which will yield a paleohistological data package in the form of electronic images.

"We plan to conduct microstructural paleontological research in collaboration with the Federal Research Center for Fundamental and Translational Medicine (FRC FTM) and my supervisor, Elena Koldysheva, Doctor of Biological Sciences and Head of the Laboratory of Molecular Mechanisms of Pathological Processes at the Federal Research Center for Fundamental and Translational Medicine (FRC FTM). This is the first time histological studies of paleontological specimens have been performed, and if the megafauna tissue staining is successful, we will digitize the resulting microscopic images. This will make them accessible to specialists from a number of scientific organizations involved in the project. Preserving the structure during analysis will allow us to identify damage caused during life: thermal and mechanical injuries, congenital pathologies, or diseases acquired during life and their consequences. It may also be possible to reconstruct the morphological composition of the mammoth organs whose tissues were analyzed," explained Nikolai Kanygin, Junior Researcher at the FRC FTM (Institute of Molecular Pathology and Pathomorphology).

Scientists involved in the study of defective mammoth tusks are confident that it is now crucial to develop and apply the maximum number of methods for studying megafauna specimens in order to obtain the maximum amount of information about the finds from Yakutia.

"Such samples, removed from permafrost layers, thaw and quickly deteriorate. Soft tissues decompose, and bones quickly dry out and turn to dust. As a result, we lose a great deal of important information that could shed light on the cause of the mammoths' extinction. There are two competing points of view: some scientists believe that these megafauna, and subsequently many other species, were exterminated by an expanding population of ancient humans, while others believe that a catastrophic event, triggering climate change 10,000-15,000 years ago, was to blame. On the other hand, the modern climate is still suitable for many extinct animal species, including mammoths. Our research on mammoth tusks will help solve these mysteries of the past," concluded Ekaterina Parkhomchuk.

The Department of Mammoth Fauna Studies is a research unit of the Academy of Sciences of the Republic of Sakha (Yakutia). The department's objectives include studying the anatomical and morphological characteristics of mammoth fauna, their taxonomic status, and ecological adaptations. A second important area of research is paleoecological studies of the late Pleistocene in Yakutia, including vegetation, natural environments, and prevailing landscapes. A third area of research is studying the burial conditions of mammoth fauna specimens, including mammoth tusks, a valuable commercial resource for residents of Yakutia's Arctic regions.

In addition to these studies, which the department conducts independently, joint research projects are conducted with leading Russian and international scientific institutions. Genetic research plays an important role, involving, for example, staff from the Institute of Molecular and Cellular Biology of the Siberian Branch of the Russian Academy of Sciences (A.S. Grafodatsky).

The department's projects involve numerous highly qualified specialists from various Russian institutes—Moscow, St. Petersburg, Novosibirsk, and Yekaterinburg. Many types of analyses are conducted abroad, at the most reputable genetic and isotope centers.

A practical method for achieving the shortest pulse duration in all-fiber lasers was developed by Sergei Kobtsev, Doctor of Physical and Mathematical Sciences and Head of the Department of Laser Physics and Innovative Technologies at Novosibirsk State University. The results of his work in this area were published in the article "Production of ultrashort pulses in fiber lasers" ("Obtaining ultrashort pulses in fiber lasers"). The article became one of the most downloaded publications of the journal "Journal of the Optical Society of America B" in July-September 2025. The research was conducted within the framework of the project "New fiber short-pulse laser systems incorporating advanced composite materials, intelligent technologies and metrological extensions," supported by the Ministry of Science and Higher Education of the Russian Federation.

Fiber lasers are a promising type of laser, distinguished by improved key user parameters—the elimination of the need for precise laser cavity tuning, effective natural heat dissipation, efficient generation, and compactness. However, producing ultrashort pulses in these lasers is a challenging task due to increased dispersion and nonlinearity, often requiring the use of bulk optical elements. Such elements significantly reduce the advantages of fiber (or solid fiber) lasers.

"Sometimes, fiber lasers are used to describe combined configurations containing only a minority of fiber components, while the majority of the optical elements are bulk. Such combined fiber-bulk lasers lose important advantages associated with solid-fiber lasers. Although such combined fiber-bulk lasers can produce pulses lasting a few femtoseconds, these configurations differ little from traditional solid-state bulk lasers with their inherent drawbacks. We were interested in the minimum pulse duration possible in solid-fiber lasers, especially with fixed polarization. It turned out that such lasers can generate pulses of picosecond duration and longer," explained Sergey Kobtsev.

The results of this work are of interest to a wide range of specialists using fiber components in research and development. The ability to generate picosecond light pulses in all-fiber lasers expands their applications while maintaining the advantages of this type of laser. Given the increasing prevalence of all-fiber lasers, their generation characteristics are of great interest.

"Fiber lasers are undergoing rapid development. A few years ago, it seemed that fiber lasers could replace all other laser types due to their significant advantages. However, numerous studies have shown that these advantages are inherent not to all fiber lasers (combined, etc.), but specifically to all-fiber lasers. It became interesting to determine at what pulse durations the all-fiber configuration could be combined with short pulses. A detailed study of the problem revealed a solution: starting with pulse durations in the picosecond range, they can be generated in all-fiber lasers with fixed polarization. The mechanism for generating ultrashort pulses is also important, but a fundamental solution has already been demonstrated," explained Sergey Kobtsev.
