Scientists from the St. Petersburg Polytechnic University have developed an innovative method for producing an alternative coffee drink. The new method guarantees the absence of both caffeine and toxic acrylamide, which forms during the roasting of plant materials, in the finished product. It is based on the use of specially selected okra seed biotypes. The development has received patent Federal Service for Intellectual Property.

The current coffee substitute market offers numerous alternatives made from plant-based sources, such as Jerusalem artichoke root or cereal grains. Researchers note that the most important problem in the production of coffee, coffee drinks, and other products is the transformation of the biochemical composition of the raw materials due to the high temperatures during roasting. When foods containing sugars and starchy substances are exposed to high temperatures, the Maillard reaction occurs, leading to the formation of acrylamide. The International Agency for Research on Cancer has classified it as carcinogenic to consumers. The formation of acrylamide involving free asparagine and sugars during the thermal processing of cereal grains has been described. To reduce acrylamide content in roasted coffee beans, enzymatic treatment of the raw materials, vacuum or steam roasting, extraction of roasted beans in a supercritical fluid, final processing of the finished beverage, and, finally, yeast fermentation and the addition of amino acids have been commonly recommended. However, these time-consuming and expensive processes degrade the characteristic flavor and reduce the health benefits of the resulting coffee alternatives. The technology developed at the Polytechnic University makes it possible to prepare a delicious, safe, and inexpensive coffee drink.

The key idea behind the proposed method lies not in the subsequent removal of harmful substances from the resulting products, but in the initial use of properly selected raw materials. The technology begins with the careful selection of specific seed chemotypes with a unique biochemical composition—okra. The raw material must have extremely low levels of sugars: sucrose, glucose, fructose, maltose, and galactose. A critical requirement is a record-high level of free glycine (over 1000 mg per 100 g of dry matter) and a near-zero content of free asparagine, an amino acid that is a precursor to acrylamide.

The selected seeds are air-dried to a moisture content of no more than 18%, then gently roasted at 170°C for no longer than 40 minutes. The cooled seeds are ground to a particle size of approximately 0.5 mm. To prepare the drink, the resulting powder is steeped in water at 95-100°C for 4-7 minutes. This process maximizes the biologically active substances in the seeds and preserves the drink's original flavor and aroma, the authors note.

The health benefits of natural coffee, as well as the potential risks of excessive consumption, are being studied worldwide. The generally accepted scientific consensus is that caffeine abuse and addiction are becoming increasingly common and can lead to intoxication, withdrawal symptoms, and an increased risk of cardiovascular disease. "Our technology paves the way for the creation of a new class of healthy and safe coffee drinks that can be harmoniously integrated into a healthy diet," noted Ksenia Illarionova, Associate Professor at the Higher School of Service and Trade of the Institute of Industrial Management, Economics, and Trade.

The Institute of Electronics and Telecommunications of SPbPU and the Special Technology Center (STC) launched a jointly manufactured nanosatellite of the 16U CubeSat standard from the Vostochny Cosmodrome – it became the sixth inPolytech Universe space satellite constellation.

PU-6 was launched into orbit by the Soyuz-2.1b launch vehicle together with the Aist-2T satellites No. 1 and No. 2 and another fifty spacecraft for various purposes.

Several hours after separation from the Fregat upper stage, the Polytech Universe No. 6 (PU-6) nanosatellite contacted ground control. Specialists then began flight and space testing of the satellite platform subsystems and the spacecraft's payloads.

The new CubeSat is designed to solve scientific and applied problems in the fields of radio monitoring, geolocation, and inter-satellite communications. Its capabilities include:

Measuring the level of electromagnetic radiation in various frequency ranges; receiving and storing AIS (automatic identification system) messages; transmitting data to the control center for processing and analysis; experimental testing of the operability of the high-speed inter-satellite radio communication system.

The previous five Polytech Universe CubeSats were smaller, comprising only three units (cubes measuring 10 cm on a side). The new PU-6 satellite is significantly larger, with 16 units. This increases its battery capacity and solar panel area, significantly increasing its active orbital time.

"Furthermore, the satellite is equipped with a new version of the onboard AIS receiver with low power consumption, allowing it to operate 24/7. It also has experimental inter-satellite communication equipment, which can improve the processing efficiency of onboard data and reduce the volume of payload data transmitted to the ground control station," explained Sergei Volvenko, a senior researcher at the Higher School of Applied Physics and Space Technology at SPbPU.

The data obtained from the satellite is also planned to be used in the university's educational process, giving students the opportunity to better understand the specifics of space missions.

The project, supported by a grant from the Planet Watch program of the Foundation for Assistance to Small Innovative Enterprises (FASIE) as part of the Space-π project, will continue the development of the Polytech Universe group, including educational programs, scientific experiments, and applied research.

Russian scientists have achieved the first-ever precise determination of the origin of special waves in plasma—Alfvén oscillations. This discovery provides the key to solving one of the key problems in the safety and efficiency of controlled thermonuclear fusion, which is particularly relevant in the development of future energy sources. The measurement technique was developed at Peter the Great St. Petersburg Polytechnic University. The experiment was conducted on the unique Globus-M2 spherical tokamak at the A.F. Ioffe Physical-Technical Institute.

Alfvén oscillations are a special type of wave that occurs in plasma (an ionized gas) in the presence of a magnetic field. With a slight perturbation, the particles and the magnetic field itself begin to oscillate together, like a string carrying a wave. These oscillations propagate along magnetic fields and are observed both in laboratory setups and in space. For his theoretical description of these oscillations, Swedish physicist Hannes Alfvén received the Nobel Prize in Physics in 1970.

In laboratory settings, Alfvén oscillations are studied using toroidal (doughnut-shaped) magnetic plasma confinement devices, such as tokamaks. This design allows hot plasma, with temperatures up to 100 million degrees Celsius, to be confined using magnetic fields, preventing it from coming into contact with the walls. Tokamaks create conditions similar to those found inside the Sun, allowing energy to be generated through thermonuclear fusion. Alfvén oscillations inside tokamaks have a dual effect. While they facilitate energy and particle transfer, they can also lead to heat loss or instabilities, which can lead to plasma escaping the magnetic field and subsequent melting of the structure's walls. Therefore, studying the physical processes inside such devices is particularly important. Existing theoretical models and computer calculations have described how these oscillations should behave, but experimentally testing the theory under the challenging conditions of a real toroidal device has previously been elusive.

St. Petersburg scientists have achieved two important results for the first time in the world while studying Alfvén oscillations in the plasma of the Globus-M2 spherical tokamak at the Ioffe Institute.

"First, we experimentally determined where exactly Alfvén oscillations originate and exist within the toroidal setup. Measurements were conducted using microwave Doppler backscatter (DBS) diagnostics, developed by scientists at the Polytechnic University. This diagnostics allowed us to measure the electric field amplitude of Alfvén oscillations directly in the region of their development. Second, we discovered that different types of Alfvén oscillations and their harmonics can have different localizations," explained Alexander Yashin, PhD in Physics and Mathematics and head of the "High-Temperature Plasma Diagnostics" research laboratory at the Institute of Physics and Mechanics at St. Petersburg Polytechnic University.

Since the plasma temperature inside the tokamak is too high, the use of standard contact sensors for measurements is limited.

The Doppler backscatter method uses microwave radiation scattered by inhomogeneities in the plasma. This allows for remote and local measurement of key parameters. To ensure reliability, the Doppler backscatter data were compared with data from magnetic probes, which are traditionally used to study the dynamics of Alfvén oscillations but cannot provide information on their location or the local value of their amplitude. The comparison showed that the different methods yield consistent results, noted Arseny Tokarev, a research assistant at the Scientific Laboratory of Advanced Methods for Studying Spherical Tokamak Plasma at the Institute of Physics and Mechanics of St. Petersburg Polytechnic University.

Alfvén oscillations lead to significant losses of fast particles in the plasma. Their role in thermonuclear fusion is difficult to overestimate. Firstly, only they have sufficient energy to approach and interact, resulting in a thermonuclear fusion reaction. Secondly, they transfer part of their energy to slower particles, thereby increasing the plasma temperature. To achieve efficient and safe thermonuclear fusion, it is important to minimize the loss of high-energy particles. For example, according to calculations, the ITER experimental thermonuclear reactor, being built by an international research team in France, will withstand no more than a two percent loss of fast particles. Alfvén oscillations can cause much more significant losses. Therefore, the experimental data on the localization of Alfvén oscillations in plasma obtained by St. Petersburg scientists is a valuable contribution to the development of global thermonuclear energy.

The research was supported by the Ministry of Science and Higher Education of the Russian Federation under the state assignment in the field of science, project No. FSEG 2024 0005, using the Federal Center for Shared Use "Materials Science and Diagnostics in Advanced Technologies" of the A.F. Ioffe Physical-Technical Institute, which includes the unique scientific facility "Spherical Tokamak Globus-M."

Scientists from the Almazov National Medical Research Center and Peter the Great St. Petersburg Polytechnic University have presented a unique hardware and software system capable of assessing the state of cerebral autoregulation—a key mechanism that protects the brain from blood pressure fluctuations—in real time. This development, which has no direct analogues anywhere in the world, will allow physicians in intensive care and neurosurgery departments to instantly obtain critical data on brain blood flow and promptly adjust treatment, potentially saving the lives of patients with strokes, traumatic brain injuries, and other severe pathologies. The results of the study are presented in an international scientific journal. Sensors.

Cerebral autoregulation (CA) is a mechanism that maintains stable blood flow in the cerebral vessels despite a decrease or increase in a person's blood pressure. This "autopilot" can malfunction, for example, after a stroke or severe traumatic brain injury. Current noninvasive methods for assessing CA require post-processing of data, which is time-consuming—two to three hours to collect, process, and analyze the information. Transforming therapeutic approaches requires obtaining data on the state of CA in real time, directly during the examination. This allows for the recording of CA indicators over time, which is especially valuable when conducting functional tests and monitoring patients' condition.

To address the problem of non-invasive, real-time assessment of the central nervous system, a team of scientists from the A. L. Polenov Russian Neurosurgical Research Institute, a branch of the V. A. Almazov National Medical Research Center, and Peter the Great St. Petersburg Polytechnic University have developed a world-class hardware and software system (HSS) for the first time in Russia. The team includes programmers Professor Galina Malykhina and Associate Professor Vyacheslav Salnikov, mathematician and professor Valery Antonov, engineer Boris Govorov, and physicians Grigory Panuntsev, Anna Nikiforova, and Anastasia Vesnina. The research team is led by pathophysiologist, Honored Scientist of the Russian Federation, and laureate of the Russian Federation State Prize for Science and Technology, Professor Vladimir Semenyutin.

In intensive care settings, the use of a CAP for rapid assessment of the cerebral circulation in patients with severe brain injury significantly accelerates the decision-making process for physicians. This is crucial for timely adjustment of cerebral perfusion pressure, which is a priority in the effective treatment of cerebral edema, secondary ischemia, and recurrent hemorrhages, noted Professor Vladimir Semenyutin, Head of the Research Laboratory of Cerebrovascular Pathology at the Almazov National Medical Research Center of the Russian Ministry of Health.

The operating principle is based on monitoring very slow, spontaneous fluctuations in blood pressure and linear blood flow velocity in the middle cerebral arteries. These are recorded using non-invasive methods—photoplethysmography and transcranial Doppler ultrasound. The key indicator is the phase shift (the difference in rhythm) between these two "pulses" in a specific low-frequency range, the so-called Mayer waves.

The scientists' key innovation is specialized mathematical algorithms that analyze these signals not afterward, but directly during the study. The system utilizes two powerful data processing methods: short-time Fourier transform and wavelet analysis (continuous wavelet transform). The latter method, according to the study, proved more sensitive and allows for better detection of the moments when autoregulation is activated or deactivated, providing higher resolution in time and frequency. All processing occurs so quickly that the results are displayed on the screen almost instantly.

The effectiveness and safety of the complex have been confirmed by clinical trials. In the first phase, it was tested on 40 healthy volunteers. They underwent standard functional tests—hypercapnia (inhalation of air with elevated CO2 levels) and hypocapnia (intensive breathing). These tests consistently alter cerebral vascular tone, which the complex recorded, demonstrating predictable changes in phase shift. The AAC was then tested on 60 patients with various neurovascular pathologies, including atherosclerotic carotid stenosis and cerebral arteriovenous malformations. These patients exhibited asymmetry in CA values between the cerebral hemispheres, and their responses to functional tests often deviated from the norm. For example, a patient with an arteriovenous malformation did not show a normal vascular response to carbon dioxide. All this proves that the complex is capable of not only recording the functioning of a healthy system, but also clearly identifying its disturbances in pathologies.

The developed hardware and software system has demonstrated high efficiency and informativeness. It can be used both for real-time diagnostics of the cerebral circulation in patients and for studying the mechanisms regulating cerebral blood flow in healthy individuals. The proposed algorithms minimize the risk of methodological errors and significantly reduce the time required to obtain information, which is especially important for making urgent decisions, noted Galina Malykhina, professor at the Higher School of Computer Technologies and Information Systems at the Institute of Computer Science and Cybersecurity at SPbPU.

The introduction of this system into clinical practice opens a new era in bedside monitoring of critically ill patients. Currently, dozens of parameters are monitored in real time in intensive care units, including blood pressure, pulse rate, oxygen saturation, and intracranial pressure. However, a key parameter—the adequacy of cerebral blood flow—remained unnoticed due to the difficulty of instantaneous assessment. The new APC integrates into this system, providing physicians with a pathogenetically based tool for personalized management of cerebral perfusion pressure. This means that therapy—for example, the selection of medications to increase or decrease blood pressure—can be based not on average standards, but on precise data on how a specific patient's blood vessels are protecting their brain at a given moment.

The scientists aren't resting on their laurels. The next step is integrating artificial intelligence into the system for in-depth data analysis. The goal is not only to diagnose the current condition but also to predict the risk of secondary vascular complications in neurosurgical patients. The use of artificial intelligence will not only allow for the early detection of functional abnormalities, when they are still treatable, but also for more accurate determination of indications for surgical treatment.

The various stages of Business Informatics Day allowed participants to try their hand at being analysts, architects, and digital project managers, demonstrating their erudition, team spirit, and sense of humor. Teams also proposed their project ideas for automating various processes at Polytechnic University, which could serve as inspiration for coursework topics and future theses.

Maxim Ivanov, Deputy Director for Promising Projects and Youth Policy at the Institute of Economics, Management and Telecommunications (IPMET), emphasized: "Event formats like these help build a new level of dialogue between generations. Students see faculty not only as mentors and examiners, but also as active participants in collaborative work, while faculty receive live and meaningful feedback from future professionals. Business informatics, in this context, is a key growth area, combining economic thinking, digital technologies, and a practice-oriented approach to teaching. These formats demonstrate the demand for interdisciplinary competencies and teamwork skills today. Forward!"

The best student teams received branded gifts with the Polytechnic logo and diplomas from the director of the Higher School of Business. This added to the emotional atmosphere of the celebration and motivated the participants to pursue further professional growth.
