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.

HSE Scientists Reveal How Disrupted Brain Connectivity Affects Cognitive and Social Behaviour in Children with Autism
An international team of scientists, including researchers from the HSE Centre for Language and Brain, has for the first time studied the connectivity between the brain's sensorimotor and cognitive control networks in children with autism. Using fMRI data, the researchers found that connections within the cognitive control network (responsible for attention and inhibitory control) are weakened, while connections between this network and the sensorimotor network (responsible for movement and sensory processing) are, by contrast, excessively strong. These features manifest as difficulties in social interaction and behavioural regulation in children. The study has been published in Brain Imaging and Behavior.
Similar Comprehension, Different Reading: How Native Language Affects Reading in English as a Second Language
Researchers from the MECO international project, including experts from the HSE Centre for Language and Brain, have developed a tool for analysing data on English text reading by native speakers of more than 19 languages. In a large-scale experiment involving over 1,200 people, researchers recorded participants’ eye movements as they silently read the same English texts and then assessed their level of comprehension. The results showed that even when comprehension levels were the same, the reading process—such as gaze fixations, rereading, and word skipping—varied depending on the reader's native language and their English proficiency. The study has been published in Studies in Second Language Acquisition.
Mortgage and Demography: HSE Scientists Reveal How Mortgage Debt Shapes Family Priorities
Having a mortgage increases the likelihood that a Russian family will plan to have a child within the next three years by 39 percentage points. This is the conclusion of a study by Prof. Elena Vakulenko and doctoral student Rufina Evgrafova from the HSE Faculty of Economic Sciences. The authors emphasise that this effect is most pronounced among women, people under 36, and those without children. The study findings have been published in Voprosy Ekonomiki.
Scientists Discover How Correlated Disorder Boosts Superconductivity
Superconductivity is a unique state of matter in which electric current flows without any energy loss. In materials with defects, it typically emerges at very low temperatures and develops in several stages. An international team of scientists, including physicists from HSE MIEM, has demonstrated that when defects within a material are arranged in a specific pattern rather than randomly, superconductivity can occur at a higher temperature and extend throughout the entire material. This discovery could help develop superconductors that operate without the need for extreme cooling. The study has been published in Physical Review B.
Scientists Develop New Method to Detect Motor Disorders Using 3D Objects
Researchers at HSE University have developed a new methodological approach to studying motor planning and execution. By using 3D-printed objects and an infrared tracking system, they demonstrated that the brain initiates the planning process even before movement begins. This approach may eventually aid in the assessment and treatment of patients with neurodegenerative diseases such as Parkinson’s. The paper has been published in Frontiers in Human Neuroscience.
Civic Identity Helps Russians Maintain Mental Health During Sanctions
Researchers at HSE University have found that identifying with one’s country can support psychological coping during difficult times, particularly when individuals reframe the situation or draw on spiritual and cultural values. Reframing in particular can help alleviate symptoms of depression. The study has been published in Journal of Community Psychology.
Scientists Clarify How the Brain Memorises and Recalls Information
An international team, including scientists from HSE University, has demonstrated for the first time that the anterior and posterior portions of the human hippocampus have distinct roles in associative memory. Using stereo-EEG recordings, the researchers found that the rostral (anterior) portion of the human hippocampus is activated during encoding and object recognition, while the caudal (posterior) portion is involved in associative recall, restoring connections between the object and its context. These findings contribute to our understanding of the structure of human memory and may inform clinical practice. A paper with the study findings has been published in Frontiers in Human Neuroscience.
Researchers Examine Student Care Culture in Small Russian Universities
Researchers from the HSE Institute of Education conducted a sociological study at four small, non-selective universities and revealed, based on 135 interviews, the dual nature of student care at such institutions: a combination of genuine support with continuous supervision, reminiscent of parental care. This study offers the first in-depth look at how formal and informal student care practices are intertwined in the post-Soviet educational context. The study has been published in the British Journal of Sociology of Education.
