HSE Scientists Take Important Step Forward in Development of 6G Communication Technologies
Researchers at HSE MIEM have successfully demonstrated the effective operation of a 6G wireless communication channel at sub-THz frequencies. The device transmits data at 12 Gbps and maintains signal stability by automatically switching when blocked. These metrics comply with international 6G standards. An article published on arXiv, an open-access electronic repository, provides a description of certain elements of the system.
For the first time in Russia, scientists at MIEM HSE have demonstrated the effective operation of a sixth-generation (6G) data transmission system. The experiment confirmed that the system can operate in a laboratory environment while maintaining high data transfer rates and a stable connection. The demonstrator operated at frequencies of 141–148.5 GHz and 151.5–164 GHz, achieving a data transfer rate of 12 Gbps. These metrics comply with international standards for sixth-generation (6G) and IMT-2030 network communication channels, specifically ETSI GR THz 002 V1.1.1 (March 2024) and ITU-R M.2160 of the International Telecommunication Union (ITU).
The system's key feature is real-time signal distribution control. If the signal is blocked, the system automatically switches to a different antenna. This ensures a stable connection, even in adverse conditions. Some of the system's components were developed at MIEM HSE and Moscow Pedagogical State University. These components include, for example, the RIS panel (compliant with ITU-R M.2541-0, May 2024), a frequency-selective surface that controls the direction of signal transmission, and diode detectors that enable operation at sub-terahertz frequencies.
Currently, the system's range is limited by the size of the room, but this can be adjusted by replacing the antennas. This technology can be useful for high-speed communication networks and IoT systems. The scientists plan to use machine learning to enhance signal distribution and improve protection against interference.
'We have demonstrated that the 6G system can reliably transmit data at the required frequencies and speeds. This is a significant step forward in the development of communication technologies. In the future, we will focus on making the system even more resilient by leveraging machine learning. For example, we plan to teach it how to automatically control the signal beam, ensuring stable communication even when users are in motion,' comments Prof. Evgeny Koucheryavy, Director of the MIEM HSE Telecommunications Research Institute.
Telecommunication companies have shown interest in the developed solution. Discussions are already underway regarding the creation of commercial devices that could compete with their foreign counterparts.

Chemists Simplify Synthesis of Drugs Involving Amide Groups
Chemists from HSE University and the Nesmeyanov Institute of Organoelement Compounds of the Russian Academy of Sciences (INEOS RAS) have developed a new method for synthesising amides, essential compounds in drug production. Using a ruthenium catalyst and carbon monoxide under precisely controlled reaction conditions, they successfully obtained the target product without by-products or complex purification steps. The method has already been tested for synthesising a key component of Vorinostat, a drug used to treat T-cell lymphoma. This approach could lower the cost of the drug by orders of magnitude. The paper has been published in the Journal of Catalysis. The study was supported by the Russian Science Foundation.
Scientists Examine Neurobiology of Pragmatic Reasoning
An international team including scientists from HSE University has investigated the brain's ability to comprehend hidden meanings in spoken messages. Using fMRI, the researchers found that unambiguous meanings activate brain regions involved in decision-making, whereas processing complex and ambiguous utterances engages regions responsible for analysing context and the speaker's intentions. The more complex the task, the greater the interaction between these regions, enabling the brain to decipher the meaning. The study has been published in NeuroImage.

Specialists at the HSE Faculty of Computer Science and Sber AI Lab have developed a geometric oversampling technique known as Simplicial SMOTE. Tests on various datasets have shown that it significantly improves classification performance. This technique is particularly valuable in scenarios where rare cases are crucial, such as fraud detection or the diagnosis of rare diseases. The study's results are available on ArXiv.org, an open-access archive, and will be presented at the International Conference on Knowledge Discovery and Data Mining (KDD) in summer 2025 in Toronto, Canada.
Hi-Tech Grief: HSE Researchers Explore the Pros and Cons of Digital Commemoration
Researchers at HSE University in Nizhny Novgorod have explored how technological advancements are transforming the ways in which people preserve the memory of the deceased and significant events. Digital technologies enable the creation of virtual memorials, the preservation of personal stories and belongings of the deceased, interaction with their digital footprint, and even the development of interactive avatars based on their online activity. However, these technologies not only evoke nostalgia and provide a sense of relief but can also heighten anxiety and fear, and delay the process of accepting loss. The study has been published in Chelovek (The Human Being).
Scientists Find Out Why Aphasia Patients Lose the Ability to Talk about the Past and Future
An international team of researchers, including scientists from the HSE Centre for Language and Brain, has identified the causes of impairments in expressing grammatical tense in people with aphasia. They discovered that individuals with speech disorders struggle with both forming the concept of time and selecting the correct verb tense. However, which of these processes proves more challenging depends on the speaker's language. The findings have been published in the journal Aphasiology.
Implementation of Principles of Sustainable Development Attracts More Investments
Economists from HSE and RUDN University have analysed issues related to corporate digital transformation processes. The introduction of digital solutions into corporate operations reduces the number of patents in the field of green technologies by 4% and creates additional financial difficulties. However, if a company focuses on sustainable development and increases its rating in environmental, social, and governance performance (ESG), the negative effects decrease. Moreover, when the ESG rating is high, digitalisation can even increase the number of patents by 2%. The article was published in Sustainability.
Russian Scientists Develop New Compound for Treating Aggressive Tumours
A team of Russian researchers has synthesised a novel compound for boron neutron capture therapy (BNCT), a treatment for advanced cancer that uses the boron-10 isotope. The compound exhibits low toxicity, excellent water solubility, and eliminates the need for administering large volumes. Most importantly, the active substance reaches the tumour with minimal impact on healthy tissues. The study was published in the International Journal of Molecular Sciences shortly before World Cancer Day, observed annually on February 4.
Scientists Discover Link Between Brain's Structural Features and Autistic Traits in Children
Scientists have discovered significant structural differences in the brain's pathways, tracts, and thalamus between children with autism and their neurotypical peers, despite finding no functional differences. The most significant alterations were found in the pathways connecting the thalamus—the brain's sensory information processing centre—to the temporal lobe. Moreover, the severity of these alterations positively correlated with the intensity of the child's autistic traits. The study findings have been published in Behavioural Brain Research.
Earnings Inequality Declining in Russia
Earnings inequality in Russia has nearly halved over the past 25 years. The primary factors driving this trend are rising minimum wages, regional economic convergence, and shifts in the returns on education. Since 2019, a new phase of this process has been observed, with inequality continuing to decline but driven by entirely different mechanisms. These are the findings made by Anna Lukyanova, Assistant Professor at the HSE Faculty of Economic Sciences, in her new study. The results have been published in the Journal of the New Economic Association.
