Researchers at HSE University and the London School of Hygiene and Tropical Medicine have identified 15 key motives that drive human behaviour. By analysing people's views, preferences, and actions through an evolutionary lens, they demonstrated how these motives intertwine to shape habits and interpersonal relationships. The findings have been published in Personality and Individual Differences.

Researchers at the HSE Centre for Language and Brain and Psychiatric Hospital No. 1 Named after N.A. Alexeev have developed a Russian-language adaptation of the Rey Auditory Verbal Learning Test. This classic neuropsychological test evaluates various aspects of auditory verbal memory in adults and is widely used in both clinical diagnostics and research. The study findings have been published in The Clinical Neuropsychologist.

Consumers of content about serial killers watch and read it to experience intense emotions that are often lacking in everyday life and to understand the reasons that drive people to commit crimes. However, such content does not contribute to increased aggression. These conclusions were drawn by sociologists from HSE University. The results of their study have been published in Crime, Media, Culture: An International Journal.

Researchers at HSE University's St Petersburg School of Economics and Management have been exploring methods for the efficient allocation of resources in systems involving multiple players. The scientists have proven the existence of strategies for optimal decision-making in competition for limited, discrete resources in four different cases. The developed mathematical model can be applied in various fields, ranging from education and medicine to managing networks and computing power. The paper has been published in Games and Economic Behaviour.

A team of researchers at HSE University investigated the neural mechanisms involved in how the brain processes persuasive messages. Using functional MRI, the researchers recorded how the participants' brains reacted to expert arguments about the harmful health effects of sugar consumption. The findings revealed that all unpersuaded individuals' brains responded to the messages in a similar manner, whereas each persuaded individual produced a unique neural response. This suggests that successful persuasive messages influence opinions in a highly individual manner, appearing to find a unique key to each person's brain. The study findings have been published in PNAS.

Researchers have proposed using polymer membranes modified with copper, zinc, and chromium metal ions for water purification. These polymers were used for the first time in water purification via electrodialysis. Copper-based membranes demonstrated record selectivity for monovalent ions, opening new possibilities for sustainable water recycling. The study has been published in the Journal of Membrane Science. 

Researchers at HSE MIEM have developed a model for calculating the electrical conductivity of aqueous electrolyte solutions; for the first time, it considers the spatial distribution of ion charges instead of assuming their localisation at a single point. The model remains effective even at high electrolyte concentrations and across a wide temperature range. This breakthrough will contribute to the development of more efficient batteries and enable the calculation of electrical conductivity without the need for experimental testing. The study has been published in the Journal of Chemical Physics.

A group of Russian scientists led by Professor Natalia Kryzhanovskaya at HSE Campus in St Petersburg has been researching microdisk lasers with an active region based on arsenide quantum dots. For the first time, researchers have successfully developed a microdisk laser coupled with an optical waveguide and a photodetector on a single substrate. This design enables the implementation of a basic photonic circuit on the same substrate as the radiation source (microlaser). In the future, this will help speed up data transfer and reduce equipment weight without compromising quality. The study results have been published in Semiconductors.

The accuracy of Russian GDP forecasts during periods of instability improves in 45% of cases when news reports are taken into account. However, during more stable periods, this advantage nearly disappears. News provides an up-to-date view of the economy and enables quicker responses to emerging challenges. This was revealed by an analysis of over 500,000 news reports conducted by Ivan Stankevich and Natalia Makeeva of the HSE Faculty of Economic Sciences (FES), and Nikita Lyubaykin. The study results have been published in Voprosy Ekonomiki.

Researchers at the HSE Institute for Cognitive Neuroscience have investigated how the emotional impact of advertising affects the amount people willing to donate to support animal welfare. To accomplish this, the researchers measured physiological responses such as heart rate, electrodermal activity, and facial expressions in individuals viewing various photos of dogs. The findings indicate that willingness to donate is most accurately predicted by heart rate and facial muscle activation. The study has been published in Social Psychology.
